Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

With the development of electronic devices, a full screen has become a development trend of mobile phones. The characteristics that the high screen of full face screen accounts for the ratio make the screen top reserve the position for proximity sensor or other components limited, when proximity sensor sets up under the printing opacity display screen, because photoelectric effect, thereby the electron of proximity sensor in the in-process messenger screen of emission infrared receives arousing printing opacity display screen scintillation to form with the normal demonstration of printing opacity display screen and interfere, influence user's experience.

Referring to fig. 1-3, an embodiment of the invention provides an electronic device 100. The electronic device 100 includes a touch display screen 10, a proximity sensor 16, a temperature sensor 21, and a processor 23. The touch display screen 10 includes a display layer 13, and the display layer 13 includes a display area 1311. The proximity sensor 16 is disposed below the touch display screen 10. Further, the proximity sensor 16 is disposed below the display area 1311. The proximity sensor 16 is used to emit infrared light and receive infrared light reflected by an object to detect a distance of the object to the electronic device 100.

By way of example, the electronic device 100 may be any of various types of computer system equipment (only one modality shown in FIG. 1 by way of example) that is mobile or portable and that performs wireless communications. Specifically, the electronic apparatus 100 may be a mobile phone or a smart phone (e.g., an iPhone (TM) based phone), a Portable game device (e.g., Nintendo DS (TM), PlayStation Portable (TM), game Advance (TM), iPhone (TM)), a laptop computer, a PDA, a Portable internet appliance, a music player and a data storage device, other handheld devices and a headset such as a watch, an in-ear headphone, a pendant, a headset, etc., and the electronic apparatus 100 may also be other wearable devices (e.g., a Headset (HMD) such as electronic glasses, electronic clothing, an electronic bracelet, an electronic necklace, an electronic tattoo, an electronic device, or a smart watch).

The electronic apparatus 100 may also be any of a number of electronic devices including, but not limited to, cellular phones, smart phones, other wireless communication devices, personal digital assistants, audio players, other media players, music recorders, video recorders, cameras, other media recorders, radios, medical devices, vehicle transportation equipment, calculators, programmable remote controllers, pagers, laptop computers, desktop computers, printers, netbook computers, Personal Digital Assistants (PDAs), Portable Multimedia Players (PMPs), moving Picture experts group (MPEG-1 or MPEG-2) Audio layer 3(MP3) players, portable medical devices, and digital cameras, and combinations thereof.

In some cases, electronic device 100 may perform multiple functions (e.g., playing music, displaying videos, storing pictures, and receiving and sending telephone calls). If desired, the electronic apparatus 1000 may be a portable device such as a cellular telephone, media player, other handheld device, wrist watch device, pendant device, earpiece device, or other compact portable device.

The mobile phone can prevent misoperation of a user and is beneficial to saving the electric quantity of the mobile phone by arranging the proximity sensor 16 to determine the distance between the mobile phone and the obstacle and making corresponding adjustment. For example, when the user is receiving or making a call and brings the mobile phone close to the head, the proximity sensor 16 generates detection information by counting the time when the transmitter emits infrared light and the receiver receives reflected infrared light, and the processor 23 touches the display screen 10 according to the detection information. When the mobile phone is far away from the head, the processor 23 turns on the touch display screen 10 again according to the detection information fed back by the proximity sensor 16.

In some embodiments, the display layer 13 comprises an OLED display layer.

Specifically, the OLED display layer has good light transmittance and can better transmit visible light and infrared light. Thus, the OLED display layer may exhibit content effects without affecting the emission and reception of infrared light by the proximity sensor 16. The display layer 13 may also be a Micro LED display layer, which also has good transmittance to visible light and infrared light. Of course, these display layers are merely exemplary and embodiments of the present invention are not limited in this respect. In addition, the touch display screen 10 may be provided on the housing 20.

Referring to fig. 3, in some embodiments, the touch display screen 10 further includes a light-transmissive cover plate 11 and a touch layer 12. The light-transmitting cover plate 11 is disposed on the touch layer 12. The touch layer 12 is disposed on the display layer 13. The upper surface 131 of the display layer 13 faces the touch layer 12. The light transmittance of the light-transmitting cover plate 11 and the light transmittance of the touch layer 12 to visible light and infrared light are both greater than 90%.

Specifically, the touch layer 12 is mainly used for receiving a user input signal and transmitting the user input signal to the circuit board for data processing, so as to obtain a specific position where the user touches the touch layer 12. It is noted that the touch layer 12 being disposed on the display layer 13 may mean that the touch layer 12 is in contact with the display layer 13. For example, the touch layer 12 and the display layer 13 may be bonded using In-Cell or On-Cell technology, which can effectively reduce the weight of the display layer 13 and the overall thickness of the display layer 13. The touch layer 12 being disposed on the display layer 13 may also mean that the touch layer 12 is disposed above the display layer 13 and spaced apart from the display layer 13.

In addition, the transparent cover plate 11 is disposed on the touch layer 12, so that the touch layer 12 and the internal structure thereof can be effectively protected, and the touch layer 12 and the display layer 13 are prevented from being damaged by external force. The light transmittance of the light-transmitting cover plate 11 and the light transmittance of the touch layer 12 to visible light and infrared light are both greater than 90%, which is not only beneficial to the display layer 13 to better display the content effect, but also beneficial to the proximity sensor 16 arranged below the display layer 13 to stably emit and receive infrared light, and ensures the normal operation of the proximity sensor 16.

Referring to FIG. 4, in some embodiments, the display layer 13 includes an upper surface 131 and a lower surface 132. The electronic device 100 also includes a first coating layer 14 coated on the lower surface 132 and covering the proximity sensor 16. The first coating layer 14 serves to transmit infrared light and intercept visible light. The proximity sensor 16 is used to emit and/or receive infrared light through the first coating layer 14 and the display layer 13.

Specifically, the first coating layer 14 is configured to transmit infrared light to ensure proper operation of the proximity sensor 16. The first coating layer 14 intercepts visible light, so that the electronic device 100 can be viewed from the outside, and the effect that the proximity sensor 16 is not visible is achieved.

Referring to fig. 4 and 5, in some embodiments, the proximity sensor 16 includes a transmitter 1611 and a receiver 1612. The emitter 1611 serves to emit infrared light through the first coating layer 14 and the display layer 13. The receiver 1612 is for receiving the infrared light emitted by the object to detect a distance of the object from the electronic device 100.

Specifically, in general, when the user is receiving or making a call, the electronic device 100 is close to the head of the human body, the transmitter 1611 emits infrared light, and the receiver 1612 receives the reflected infrared light. The processor 23 calculates the time from the emission of the infrared light to the reflection of the infrared light, and then sends a corresponding instruction to control the screen to be closed. When the electronic device 100 is far away from the head, the processor 23 performs calculation again according to the data fed back and sends an instruction, so that the screen is turned on again. Therefore, misoperation of the user is prevented, and the electric quantity of the mobile phone is saved.

In certain embodiments, the orthographic projection of the proximity sensor 16 on the lower surface 132 is within the orthographic projection of the first coating layer 14 on the lower surface 132.

Specifically, the proximity sensor 16 is usually installed with a reserved assembly gap during the process of assembly, which results in a gap between the proximity sensor 16 and other elements, so that visible light enters from the gap and leaks. Therefore, in the direction in which the proximity sensor 16 and the display layer 13 are stacked, the area of the orthographic projection of the first coating layer 14 on the lower surface 132 is larger than the area of the orthographic projection of the proximity sensor 16 on the lower surface 132, so that the proximity sensor 16 can be sufficiently shielded by the first coating layer 14 without affecting the normal operation of the proximity sensor 16, and the effect that the proximity sensor 16 is not visible when the electronic device 100 is viewed from the outside can be achieved.

Referring to fig. 5, in some embodiments, an orthographic projection of the proximity sensor 16 on the lower surface 132 is coincident with the first coating layer 14.

Specifically, in the direction in which the proximity sensor 16 and the display layer 13 are laminated, the area of the lower surface 132 onto which the first coating layer 14 is orthographically projected may also be set equal to the area of the lower surface 132 onto which the proximity sensor 16 is orthographically projected. In this way, the first coating layer 14 can just shield the proximity sensor 16 without affecting the normal operation of the proximity sensor 16, and the effect that the proximity sensor 16 is not visible when the electronic device 100 is viewed from the direction towards and perpendicular to the upper surface 131 of the display layer 13 is achieved.

Referring to fig. 6, further, in this embodiment, the electronic device 100 further includes a light shielding layer 17 disposed on the lower surface 132 and surrounding the proximity sensor 16.

Specifically, when the area on which the first coating layer 14 is disposed to be projected on the lower surface 132 is equal to the area on which the proximity sensor 16 is disposed to be projected on the lower surface 132, a light leakage phenomenon occurs around the space around the proximity sensor 16 when the electronic device 100 is viewed from the external environment due to the fact that the volume of the space where the proximity sensor 16 is placed is larger than the volume of the proximity sensor 16. Therefore, by providing the light shielding layer 17 surrounding the proximity sensor 16, the gap between the proximity sensor 16 and the surrounding space is filled, and this light leakage phenomenon can be eliminated. The light shielding layer 17 may be foam made of black material, or other black foam plastics or rubber. Of course, these materials are merely exemplary and embodiments of the present invention are not limited in this respect.

In certain embodiments, the first coating layer comprises an IR ink having a transmittance of greater than 85% for infrared light, a transmittance of less than 6% for visible light, and a wavelength of infrared light that is visible through the IR ink in the range of 850nm to 940 nm.

Specifically, since the IR ink has a characteristic of low transmittance to visible light, the proximity sensor 16 disposed under the first coating layer 14 is not observed based on the visual sense of human eyes when the electronic device 100 is viewed from the outside. Meanwhile, the IR ink has a characteristic of high transmittance to infrared light, and can enable the proximity sensor 16 to stably emit and receive infrared light, thereby ensuring normal operation of the proximity sensor 16.

Referring to fig. 7 and 8, in some embodiments, the electronic device 100 further includes a second coating layer 15 coated on the lower surface 132 and connected to the first coating layer 14.

Specifically, the first coating layer 14 is mainly used for transmitting infrared light and blocking the proximity sensor 16, but since the cost of the IR ink used for the first coating layer 14 is higher than that of the ordinary black ink, it is not favorable to reduce the production cost if the lower surface 132 is entirely coated with the IR ink, and the ordinary black ink can achieve lower transmittance of visible light than the IR ink and more excellent blocking effect. Therefore, the second coating layer 15 is arranged, so that the production cost is reduced, and the shielding effect meets the process requirement.

Referring to fig. 9 and 10, in some embodiments, electronic device 100 further includes a buffer layer 18 covering lower surface 132 and avoiding proximity sensor 16.

Specifically, the buffer layer 18 is used to buffer impact and resist shock so as to protect the touch layer 12 and the display layer 13 and the internal structure thereof, and prevent the display layer 13 from being damaged due to external impact. Cushioning layer 18 may be made of foam or rubber or other soft material. Of course, these cushioning materials are merely exemplary and embodiments of the present invention are not limited in this respect. In addition, the proximity sensor 16 is shielded during the process of disposing the buffer layer 18 in order to prevent the buffer layer 18 from shielding the proximity sensor 16 from being affected during the process of emitting and receiving infrared light by the proximity sensor 16.

Referring to fig. 11 and 12, further, in such an embodiment, electronic device 100 further includes a metal sheet 19 covering buffer layer 18 and avoiding proximity sensor 16.

Specifically, the metal sheet 19 is used for shielding electromagnetic interference and grounding, and has a function of diffusing temperature rise. The metal sheet 19 may be cut out of a metal material such as copper foil or aluminum foil. Of course, these metal materials are merely exemplary and embodiments of the present invention are not limited thereto. In addition, the proximity sensor 16 is avoided during the process of disposing the metal sheet 19 in order to prevent the metal sheet 19 from shielding the proximity sensor 16 from being affected during the process of emitting and receiving infrared light by the proximity sensor 16.

Referring to fig. 13-15, in some embodiments, the electronic device 100 further includes a housing 20, a housing case 200, a light guide 51, and a light sensor 5. The receiving case 200 is slidably coupled to the housing 20 and can be extended out of the housing 20 or retracted into the housing 20. The receiving case 200 is provided with a light inlet hole 2006, and the light guide 51 is received in the receiving case 200 and partially extends into the light inlet hole 2006. The light guide 51 has a light incident surface 511 and a light emitting surface 512 opposite to each other. The light incident surface 511 faces the outside of the housing case 200. The light emitting surface 512 faces the interior of the accommodating case 200. The light sensor 5 is accommodated in the accommodating case 200 and faces the light emitting surface 512.

In this way, since the light inlet 2006 is provided in the housing case 200 of the electronic device 100, not in the touch display screen 10 of the electronic device 100, the light inlet 2006 can satisfy the requirement of the photosensor 5 for receiving ambient light, and the screen occupation ratio of the touch display screen 10 is not limited, so that the screen occupation ratio of the electronic device 100 is large.

Specifically, referring to fig. 13-14, the electronic device 100 is defined with reference to the viewing angle, and the electronic device 100 has a width direction X, a length direction Y and a thickness direction Z, wherein the length direction Y is perpendicular to the width direction X, and the thickness direction Z is perpendicular to the width direction X and the length direction Y.

The housing 20 also includes a top face 1002 and a bottom face 1003 disposed opposite the top face 1002. Generally, the top end face 1002 and the bottom end face 1003 may extend in the width direction X. I.e., the top 1002 and bottom 1003 surfaces are the short sides of the electronic device 100. The bottom face 1003 is used for arranging connectors, microphones, speakers, etc. of the electronic device 100.

As shown in fig. 14, a receiving groove 1004 is formed on the top of the housing 20, and the receiving groove 1004 is recessed from the top of the housing 20 to the inside of the housing 20. The receiving groove 1004 penetrates through a side surface of the housing 20. The accommodating case 200 is slidably connected to the housing 20 in the accommodating groove 1004. In other words, the receiving case 200 is slidably coupled to the housing 20 to extend or retract the receiving groove 1004.

The housing case 200 may further include a functional element 300, the functional element 300 may be, for example, a camera, an earpiece, a laser emitter, or the like, the camera is exposed through the light inlet 2006, and for example, the functional element 300 is exposed through the light inlet 2006 on the side surface of the housing case 200. When the receiving case 200 is extended out of the housing 20, the camera may capture an external image of the electronic device 100. The camera is, for example, a camera such as an RGB camera.

In some embodiments, the receiving case 200 has an outer side surface, and the light incident surface 511 partially or totally protrudes from the outer side surface. Thus, the housing 200 has less shielding effect on the light incident surface 511, and even does not shield the light incident surface 511 at all, so that the light incident surface 511 can receive more ambient light, and the light guide member 5151 can better guide the external light to enter the light sensor 5.

In the present embodiment, the outer side surface of the housing case 200 includes a top surface 2003, and the top surface 2003 is provided with a light entrance hole 2006. The light guide 51 corresponds to the light entry hole 2006 in the top surface 2003. Alternatively, the light sensor 5 receives light through the light guide 51 through the light entry hole 2006 in the top surface 2003. In this way, the light sensor 5 can sense ambient light regardless of whether the housing case 200 is extended or retracted into the housing body 20. The light incident surface 511 is partially or entirely convex with respect to the top surface 2003.

Referring to fig. 15-17, the light incident surface 511 has a central region 5111 and an edge region 5112 surrounding the central region 5111. The central zone 5111 is convex relative to the edge zone 5112. At this time, the area of the light incident surface 511 is larger, and more external light can enter the light guide 51. The light incident surface 511 is an arc surface.

In some embodiments, the housing case 200 has an inner side surface 2063, the inner side surface 2063 forms a positioning groove 2064, the positioning groove 2064 communicates with the light incident hole 2006, the light guiding member 51 includes a light incident portion 513 and a light emergent portion 514, the light incident portion 511 is an end surface of the light incident portion 513 facing away from the light emergent portion 514, the light emergent portion 512 is an end surface of the light emergent portion 514 facing away from the light incident portion 513, the light incident portion 513 penetrates through the light incident hole 2006, and part or all of the light emergent portion 514 is embedded in the positioning groove 2064.

At this time, the light guide 5151 and the receiving case 200 are fixed to each other and are not easily slid. Meanwhile, a sealing member may be bonded to a surface of the light exit portion 514 facing the light entrance portion 513513, and the sealing member may be continuously provided around the light entrance portion 513513. The sealing member is pressed against the light emitting portion 514 and the groove wall surface of the positioning groove 2064 to achieve sealing, so as to prevent external dust, water vapor and the like from entering the interior of the accommodating case 200 through the light inlet 2006.

In some embodiments, the area of the light exiting surface 512 is larger than that of the light entering surface 511, and the cross-sectional area of the light entering portion 513 increases in a direction from the light entering surface 511 to the light exiting surface 512.

Specifically, the shape of the light incident portion 513 is substantially a truncated cone, which facilitates the transmission of light in the light incident portion 3513, and can be diffused to uniformly enter the light exit portion 514.

In some embodiments, the light guide 51 further includes a positioning portion 515, the positioning portion 515 and the light emitting portion 514 enclose an accommodating space 516, and the accommodating space 516 is used for accommodating the light sensor 5. The light sensor 5 accommodated in the accommodating space 516 can be protected by the positioning portion 515 and the light emitting portion 514, so as to avoid damage when the electronic device 100 falls or is impacted. A gap is formed between the light-emitting surface 512 and the photosensitive area 52 of the light sensor 5.

Referring to fig. 18, a method for controlling an electronic device 100 is provided. The control method comprises the following steps:

s10, controlling the touch display screen 10 to enter a proximity detection state;

s11, acquiring an output signal of the touch display screen 10;

s12, judging whether the touch display screen 10 triggers touch operation according to the output signal;

s13, if the touch display screen 10 triggers a touch operation, controlling the touch display screen 10 to enter a touch detection state; and

s14, controlling the touch screen 10 to return to the proximity detection state after controlling the electronic device 100 to perform an operation corresponding to the touch operation according to the output signal.

In some embodiments, the processor 23 is configured to control the touch display screen 10 to enter a proximity detection state, and further configured to collect an output signal of the touch display screen 10, and determine whether the touch display screen 10 triggers a touch operation according to the output signal. When the touch display screen 10 triggers a touch operation, the processor 23 is configured to control the touch display screen 10 to enter a touch detection state, and control the touch display screen 10 to return to a proximity detection state after controlling the electronic device 100 to perform an operation corresponding to the touch operation according to the output signal.

Referring to fig. 19, an embodiment of the present invention further provides a control device 2000 of the electronic device 100, and a control method of the electronic device 100 according to the embodiment of the present invention can be implemented by the control device 2000 of the electronic device 100 according to the embodiment of the present invention.

Specifically, the control device 2000 includes an acquisition module 210, a processing module 220, and a control module 230. The control module 230 is used for controlling the touch display screen 10 to enter a proximity detection state. The collecting module 210 is used for collecting the output signal of the touch display screen 10. The processing module 220 is configured to determine whether the touch display screen 10 triggers a touch operation according to the output signal. The control module 230 is further configured to control the touch display screen 10 to enter a touch detection state, and control the touch display screen 10 to return to a proximity detection state after controlling the electronic device 100 to perform an operation corresponding to the touch operation according to the output signal.

That is, steps S10, S13, and S14 may be implemented by the control module 230. The step S11 may be implemented by the acquisition module 210, and the step S12 may be implemented by the processing module 220.

In the control method, the control device 2000 and the electronic device 100 of the embodiment of the application, the conventional state of the touch display screen 10 is set to be the proximity detection state, so that the proximity action can be detected at any time, and compared with the conventional state in which the touch display screen is in the touch detection state, the communication service is switched to be the proximity detection mode, so that the time for initializing after the touch detection state is switched to be the proximity detection state is saved, the speed of proximity detection of the touch display screen 10 is increased, and the user experience is improved.

Specifically, the touch display screen 10 is, for example, a capacitive touch display screen, the touch display screen 10 may output different capacitance values according to the distance between the object and the touch display screen 10, and whether the touch display screen 10 is shielded or not may be determined according to the capacitance value output by the touch display screen 10 and the number of the capacitance values. For example, the number of capacitance values output by the touch display screen 10 is 10, and when the 10 capacitance values are all larger than the threshold value and substantially consistent, it is determined that the touch display screen 10 is blocked.

In one example, when the electronic device 100 enters a call service, a user generally places the electronic device 100 near the ear, and in the process of placing the electronic device 100 near the ear, because parts with skin, such as the face and the ear, are conductors, the touch display screen 10 may generate different signal values according to the distance between the electronic device 100 and the head of the human body, so as to determine whether the user has finished placing the electronic device 100 near the ear, and thus control whether the proximity sensor 16 is turned on.

The touch display screen supporting the floating touch control comprises two capacitance signals, namely a mutual capacitance signal and a self-capacitance signal. The self-capacitance signal has higher strength than the mutual capacitance signal, can detect farther finger induction, and the detection distance range can reach 20 mm. The electric field of the mutual capacitance signal is so small that the signal strength is so low that very weak signals cannot be sensed. Therefore, when the user's finger hovers over the screen, hover detection of the finger is not possible according to the mutual capacitance signal.

In this embodiment, when the touch display screen 10 performs proximity detection, it is determined whether an object is close to the touch display screen 10 according to the self-capacitance signal, when touch determination is performed in a proximity detection state, it may be determined whether touch operation is performed according to a change degree of the self-capacitance signal, and when the touch display screen is in a touch detection state, it may be determined whether touch operation is performed according to the mutual capacitance signal.

In the operation process, the touch display screen 10 enters a touch detection state after the electronic device 100 is started, and in the touch detection state, whether a user has a touch operation is detected by detecting a mutual capacitance signal of the touch display screen 10, when the electronic device 100 enters a call service, the touch display screen 10 is switched to a proximity detection state, after the touch detection state is switched to the proximity detection state, reference data of a capacitor needs to be acquired in the proximity detection state for initialization, and then whether an object is close to the touch display screen 10 is detected according to a self-capacitance signal, so that the display state of the touch display screen 10 is controlled.

Because the self-capacitance signal intensity is high, and the interference of external environmental factors such as brightness, temperature and the like on the self-capacitance signal is high, the capacitance reference data needs to be obtained again according to the current environment for initialization after entering the proximity detection state every time, the time consumption of the initialization process is generally 0.3-0.5s, and the identification speed of the proximity detection of the touch display screen is influenced.

The call service includes incoming call, outgoing call or call connection. Further, the call service may be a process of voice conversation for the user, for example, the call service is a process of the user making a call to another person and waiting for the other party to answer, that is, an outgoing call state; the process that the user is conversing with other people through voice, namely the call-on state can also be realized; the electronic device 100 may also wait for the user to answer the incoming call, i.e., the incoming call state, for the incoming call to be made from the outside.

In the present application, the conventional state of the touch display screen 10 is set to be the proximity detection state, that is, the proximity detection can be performed at any time without waiting for the initialization process, and in the process that the touch display screen 10 is in the proximity detection state, it can still be determined whether the touch operation is performed according to the self-capacitance signal of the touch display screen 10. Generally, the amount of change of the self-capacitance signal caused by the touch operation of the finger is larger than the amount of change of the self-capacitance signal caused by the approach of the ear or the face. When the finger touch is judged, the fact that the user triggers the touch operation can be confirmed. At this time, the touch display 10 is controlled to switch from the proximity detection state to the touch detection state, and for the touch detection state, since the influence of the environmental factors on the mutual capacitance signal is small and can be ignored, after the initialization is completed by the initial start of the electronic device 100, the operation such as re-acquiring the calibration value to perform the initialization is not needed any more, so that the touch detection can be performed immediately.

After the electronic device 100 performs the operation corresponding to the touch operation, the touch display screen 10 returns to the proximity detection state again, and the initialization is completed. It can be understood that the initialization after switching to the proximity detection state is completed before the proximity detection is actually needed, so that the initialization time is saved, the touch display screen 10 can perform the touch detection and the proximity detection in real time, and the user experience is improved.

Referring to fig. 20, in some embodiments, the control method further includes the steps of:

s15: judging whether the touch display screen 10 triggers the approach operation according to the output signal;

s16: if the touch display screen 10 triggers the approach operation, the display state of the touch display screen 10 is controlled according to the output signal.

In some embodiments, the processor 23 is configured to determine whether the touch display screen 10 triggers a proximity operation according to the output signal, and control a display state of the touch display screen 10 according to the output signal when the touch display screen 10 triggers the proximity operation.

In certain embodiments, step S15 may be implemented by the processing module 220 and step S16 may be implemented by the control module 230. Or, the processing module 220 is configured to output a signal to determine whether the touch display screen 10 triggers the proximity operation, and the control module 230 is configured to control the display state of the touch display screen 10 according to the output signal when the touch display screen 10 triggers the proximity operation.

Specifically, when the electronic device 100 is shipped from a factory, a data model for proximity detection may be stored in the electronic device 100, that is, data of a change in a self-capacitance signal of the touch display screen 10 when a human ear or a human face approaches the touch display screen 10, and in an actual operation, the processor 23 compares the change in the data of the self-capacitance with the data model to determine whether to trigger a proximity operation. It should be noted that, in the embodiment of the present application, the touch display screen 10 can only be used for detecting the proximity action, but cannot detect the distance action, and it can be understood that, after the proximity action is determined to be triggered, the touch display screen 10 is turned off and no electric signal is generated any more, at this time, the proximity sensor 16 is turned on, and whether the distance action is triggered is determined by the proximity sensor 16. In the embodiment of the present application, the proximity sensor 16 is provided below the touch display screen 10.

Referring to fig. 21, in some embodiments, step S16 includes:

s161: judging whether the touch display screen 10 is shielded or not according to the output signal; and

s162: and when the touch display screen 10 is shielded, controlling the touch display screen 10 to enter an off state.

In some embodiments, the processor 23 is configured to determine whether the touch display screen 10 is blocked according to the output signal, and control the touch display screen 10 to enter an off state when the touch display screen 10 is blocked.

In some embodiments, the steps S161 and S162 may be implemented by the control module 230, or the control module 230 is configured to determine whether the touch display screen 10 is blocked according to the output signal, and control the touch display screen 10 to enter the off state when the touch display screen 10 is blocked.

Specifically, the display state of the touch display screen 10 can be controlled according to the output signal of the touch display screen 10, so that the electronic device 100 controls the touch display screen 10 to enter the off state when the call is made and the touch display screen 10 is blocked, so as to save power.

Specifically, in step S122, the extinguished state of the touch display screen 10 includes the display area 1311 being in a fully extinguished state; or a part of the display area 1311 displays predetermined contents while the other part of the display area 1311 is in a turned-off state. When the display area 1311 is in the fully-off state, the touch display screen 10 is powered off, and the display area 1311 appears black.

A part of the display area 1311 displaying predetermined content and the other part of the display area 1311 being in a turned-off state means that only a part of the display area 1311 is in a lit state and predetermined content is displayed, and the other part of the display area 1311 is in a turned-off state.

For example, when only a part of the display area 1311 is in an on state and predetermined content is displayed, the touch display screen 10 is in an off aod (always on display) mode. The predetermined content is, for example, time, that is, the display area 1311 can display time information regardless of whether the touch display screen 10 enters a sleep state or an awake state. Of course, the predetermined content may be a date, a signal strength of the electronic device 100, or the like.

In contrast, the lighting state of the touch display screen 10 means that the touch display screen 10 is powered on and all areas of the display area 1311 are lit so that the display area 1311 can display content.

Referring to fig. 22, in some embodiments, step S162 includes:

s1621: judging whether the distance between the touch display screen 10 and an external object is smaller than a preset distance or not according to the output signal;

s1622: determining that the touch display screen 10 is occluded when the distance is less than the predetermined distance; and

s1623: and controlling the touch display screen 10 to enter an off state.

In some embodiments, the processor 23 is configured to determine whether the distance between the touch display screen 10 and the external object is less than a predetermined distance according to the output signal, determine that the touch display screen 10 is blocked when the distance is less than the predetermined distance, and control the touch display screen 10 to enter the off state.

In some embodiments, steps S1621 to S1623 may be implemented by the control module 230, or the control module 230 is configured to determine whether a distance between the touch display screen 10 and an external object is less than a predetermined distance according to the output signal, and determine that the touch display screen 10 is blocked and control the touch display screen 10 to enter the off state when the distance is less than the predetermined distance.

Preferably, the control method further includes the step of detecting whether the posture of the electronic device 100 is a predetermined posture.

In this step, the attitude of the electronic device 100 may be detected by a sensor such as a gyroscope of the electronic device 100.

In this way, the process of controlling the display state of the touch display screen 10 is more accurate. It can be understood that, in some scenarios, even if the electronic device 100 enters a call service, it is not necessarily determined that the user has finished placing the electronic device 100 to the ear according to the signal output by the touch display screen 10. For example, after the electronic device 100 enters a call service, a finger of the user touches the touch display screen 10, and in this process, the electronic device 100 is not placed at the ear of the user, but the touch display screen 10 may output different capacitance signals.

Through the determination of the posture of the electronic device 100, it can be further determined whether the electronic device 100 is placed beside the user's ear. Specifically, the posture of the electronic device 100 may be determined by a sensor such as a gyroscope or a gravity sensor. In addition, the electronic apparatus 100 has a plurality of postures, such as horizontal, upside down, and vertical, since the user generally has a hand-raising action to place the electronic apparatus 100 at the ear of the user vertically when the user is in a call, the predetermined posture may be set such that the electronic apparatus 100 is in the vertical posture after the user raises his hand. It is understood that the process of the user lifting the hand may be detected by a sensor such as a gyroscope, a gravity sensor, etc. of the electronic device 100.

For example, when the posture of the electronic device 100 is detected by the gravity sensor, the gravity sensor can detect changes in acceleration of the electronic device 100 in three directions, i.e., the width direction X, the length direction Y, and the thickness direction Z. The gravity sensor continuously acquires data in the X direction, the Y direction, and the Z direction of the electronic device 100. It can be understood that when the electronic device 100 is placed beside the ear and in the process of talking, the electronic device 100 moves a small distance in both the X direction and the Y direction. Therefore, the gravity sensor detects a small amount of data change in the X direction and the Y direction.

If the electronic device 100 is held from the ear to the front of the eye, the moving distance of the electronic device 100 in at least two directions of the X direction, the Y direction, and the Z direction is large, and thus, the data change amount acquired by the gravity sensor in at least two directions of the X direction, the Y direction, and the Z direction is large.

Thus, the posture of the electronic device 100 can be obtained from the data change amounts obtained by the gravity sensor in the X direction, the Y direction, and the Z direction.

As another example, when the attitude of the electronic device 100 is detected by a gyroscope, the gyroscope measures the rotational angular velocity at which the electronic device 100 is deflected and tilted. The gyroscope can detect and sense the linearity and motion of a 3D space, and thus can recognize a direction, determine a posture, and calculate an angular velocity. In this way, it can be determined whether the posture of the electronic apparatus 100 is an upright posture, a flat posture, a tilted posture, or the like, based on the detection data of the gyroscope.

In step S1621, as described above, the distance between the touch display screen 10 and the object may be determined according to the different capacitance values output by the touch display screen 10 and the number of capacitance values.

In certain embodiments, step S161 comprises:

and judging whether the touch display screen 10 is shielded or not according to the control signal output by the top area of the touch display screen 10.

In some embodiments, the processor 23 is configured to determine whether the touch display screen 10 is occluded based on the output signal of the top area of the touch display screen 10.

In some embodiments, the control module 230 is configured to determine whether the touch display screen 10 is occluded according to the output signal of the top area of the touch display screen 10.

Since the receiver of the electronic device 100 is typically arranged on top of the electronic device 100. In one example, the top of the electronic device 100 is closer to the ear when the user answers the phone call, and therefore, determining whether the touch screen 10 is occluded based on the signal output from the top area of the touch screen 10 may improve the accuracy of determining that the electronic device 100 is close to the head.

In this embodiment, the top area of the touch display screen 10 refers to an area where the touch display screen 10 is close to the top end surface 1002 of the electronic device 100 in the Y direction.

In some embodiments, the control method further comprises the steps of:

after controlling the display state of the touch display screen 10 according to the output signal, the touch display screen 10 is controlled to return to the proximity detection state.

In some embodiments, the processor 23 is configured to control the touch display screen 10 to return to the proximity detection state after controlling the display state of the touch display screen 10 according to the output signal.

In some embodiments, the control module 230 is configured to control the touch display screen 10 to return to the proximity detection state after controlling the display state of the touch display screen 10 according to the output signal.

When the current proximity detection is completed, the touch display screen 10 enters the proximity detection state again and completes the required initialization operation instead of returning to the touch detection state, so that the subsequent proximity detection can be performed quickly.
