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 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 accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

Electronic devices, such as mobile phones or tablet computers, generally have infrared sensors installed to detect the distance between the electronic device and a user. Taking a mobile phone as an example, an infrared sensor is arranged in the upper area of the mobile phone. When a user carries out voice call or related operation, the mobile phone is close to the head, the infrared sensor feeds distance information back to the processor, and the processor executes corresponding instructions, such as closing light of the display screen assembly. In the related art, the infrared sensor disposed on the electronic device needs to be provided with corresponding holes for transmitting and receiving infrared signals, but with the development of the electronic device, the requirements of people on the appearance and the operation experience of the mobile phone are higher and higher. The mobile phone has been developed towards the direction of the full-screen, and the full-screen mobile phone forms an ultra-narrow frame between the casing and the display screen assembly, and because the width of the ultra-narrow frame is too small, the ultra-narrow frame may not have enough space to open a hole, so that the overall strength of the frame is reduced even if the hole is opened, and further the reliability of the electronic equipment is low.

Referring to fig. 1, an electronic device 100 according to an embodiment of the invention includes a housing 20. The electronic device 100 may be a mobile phone or a tablet computer. The electronic device 100 according to the embodiment of the present invention is described by taking a mobile phone as an example, but it is to be understood that the specific form of the electronic device 100 may be other, and is not limited herein.

Referring to fig. 2-4, in the embodiment of the invention, the electronic device 100 includes a cover plate 11, a display 13, a light sensor 40 and a processor (not shown), the display 13 is disposed below the cover plate 11, the light sensor 40 is laterally juxtaposed with the cover plate 11, and the light sensor 40 is configured to sense a light signal laterally transmitted from inside the cover plate 11. The processor controls the display 13 according to the light signals sensed by the light sensors.

The lateral arrangement of the light sensor 40 is understood to mean that the light receiving surface of the light sensor 40 faces the end of the cover plate 11 where light is incident, i.e. the end receiving light, so that the light sensor 40 can normally receive light. The juxtaposition is to be understood in a broad sense, for example, the light sensor 40 and the cover plate 11 may be arranged at a distance, i.e. there may be a certain gap between the light sensor 40 and the cover plate 11, for example, the light sensor 40 may be partially or fully arranged on the cover plate 11, i.e. there may be an overlap between the light sensor 40 and the cover plate 11. Generally, the cover plate 11 can transmit light, the light is reflected and transmitted in the cover plate 11, and the light is transmitted along the transverse direction of the cover plate 11, so that the light can be transmitted to the optical sensor 40 transversely arranged in parallel with the cover plate 11, so that the optical sensor 40 and the cover plate 11 are transversely arranged in parallel to ensure that the electronic device 100 realizes the effect of a full screen, and in addition, the space utilization rate of the electronic device 100 is improved. The processor automatically controls the display 13 to enhance the user experience and convenience of the electronic device 100.

When the light sensor 40 receives different light intensities, currents with different intensities are generated, so that the ambient light brightness is sensed. For example, when the user is under the sun, the ambient light is strong, the light sensor 40 feeds back the light intensity of the environment to the processor, and the processor executes corresponding instructions to enhance the brightness of the display 13 to adapt to the light intensity of the current environment, so that the content of the screen viewed by the user is clearer. When the user is in a dark environment, the ambient light is weak, the light sensor 40 feeds back the light intensity of the environment to the processor, and the processor executes corresponding instructions to reduce the brightness of the display 13 to adapt to the light intensity of the current environment, so that the user does not feel dazzling when watching the screen content, thereby giving the optimal visual effect to the user. Therefore, the method is not only beneficial to protecting the eyesight of the user, but also saves the electric quantity of the mobile phone and can further achieve the effect of prolonging the service life of the battery. Further, the light sensor 40 may also be used to adjust the white balance when the user is using the photographing function.

Referring to fig. 3-5, in some embodiments, the electronic device 100 includes a housing 20, the housing 20 includes a bottom wall 22 and a side wall 24 extending from an edge of the bottom wall 22, the bottom wall 22 and the side wall 24 define a groove 26, the side wall 24 surrounds the cover plate 11, and the light sensor 40 is located between the cover plate 11 and the side wall 24 and partially extends into the side wall 24.

The housing 20 is provided with a recess 26 for receiving the electronic device 100, so as to protect the electronic device 100. The casing 20 encloses the electronic device 100 by disposing the electronic device 100 in the casing 20, so as to prevent external factors from directly damaging the internal components of the electronic device 100. The housing 20 may be formed by CNC machining of an aluminum alloy, or may be injection molded using Polycarbonate (PC) or PC + ABS material. Since the cover plate 11 is limited in area, there may be a case where it is not enough to completely receive the optical sensor 40, and thus a part of the optical sensor 40 may be protruded into the sidewall 24 to save the space of the cover plate 11.

Referring to fig. 4-5 and 7-8, in some embodiments, the cover plate 11 includes a cover plate upper surface 115, a cover plate lower surface 115 disposed opposite to the cover plate upper surface, and a side surface 112 surrounding the cover plate upper surface 111 and the cover plate lower surface 113, wherein a receiving groove 114 is formed on the side surface 112, and the optical sensor 40 is at least partially received in the receiving groove 114. The optical sensor 40 is accommodated in the accommodating groove 114, so that the space utilization rate of the cover plate 11 can be improved, the optical sensor 40 can be protected to a certain extent, and the arrangement of the optical sensor 40 is stable.

In some embodiments, the light shielding layer 118 is disposed on the top 1142 of the receiving groove 114. In this way, ambient light can be prevented from entering the light sensor 40 from other places of the cover plate 11 to reduce the accuracy of the light sensor 40 in detecting ambient light, and the light sensor 40 can be shielded to maintain the consistency of the appearance of the electronic device 100.

In some embodiments, the light sensor 40 comprises an ambient light sensor for sensing ambient light, and the processor is configured to adjust the brightness of the display 13 based on the intensity of light sensed by the ambient light sensor 40.

Specifically, when the user is under the sun, the ambient light is strong, the ambient light receiver feeds back the light intensity of the environment to the processor, and the processor executes corresponding instructions to enhance the brightness of the display screen 13 to adapt to the light intensity of the current environment, so that the content of the screen viewed by the user is clearer. When the user is in a dark environment, the ambient light is weak, the ambient light receiver feeds back the light intensity of the environment to the processor, and the processor executes corresponding instructions to reduce the brightness of the display 13 to adapt to the light intensity of the current environment, so that the user does not feel dazzling when watching the screen content, and the optimal visual effect is provided for the user. Therefore, the method is not only beneficial to protecting the eyesight of the user, but also saves the electric quantity of the mobile phone and can further achieve the effect of prolonging the service life of the battery.

In some embodiments, the number of the light sensors 40 is two, and two light sensors 40 are respectively disposed on two opposite sides of the cover plate 11 in the lateral direction.

Specifically, when being mounted, the optical sensor 40 is disposed in the receiving groove 114 on both lateral sides of the cover plate 11. Because the cover plate 11 includes the curved surface portion 112 and the light sensor 40 receives visible light through the curved surface portion 112, if only one light sensor 40 is adopted, when a user uses the cover plate in the same environment, the angle at which the light sensor 40 receives visible light changes when the user tilts the display 13, so that the brightness of the display 13 changes obviously, and the user experience is affected. Therefore, the left side and the right side of the display screen 13 or the two sides of the cover plate 11 are respectively provided with the optical sensors 40, the angles of the two for receiving visible light are mutually compensated, and the accuracy of dimming can be ensured.

In the embodiment of the invention, when the display 13 is laid flat, the angles at which the two light sensors 40 receive visible light are the same, the received data are the same, and the data received by the two light sensors 40 are specified as the difference value of 0; when the display 13 is tilted, one of the light sensors 40 receives a larger data value, and the other light sensor 40 receives a smaller data value, and if the increased data value is the same as the decreased data value, the ambient light is determined to be unchanged without adjusting the brightness of the display 13. Further, in some examples, the processor may take 50% of the data from each light sensor 40 as the value to adjust the brightness. In other examples, when the display 13 is tilted toward any one of the light sensors 40, the angle at which the light sensor 40 in the tilted direction receives the visible light is reduced, and the angle at which the other light sensor 40 receives the visible light is increased, so that the received data of the two light sensors are inconsistent, at this time, the processor may use the average value of the two data as the value for adjusting the brightness, and accurately adjust the brightness of the display 13, thereby ensuring better user experience. In addition, in some examples, two photosensors 40 may be symmetrically disposed within the formed receiving slot 114. In other examples, the two photosensors 40 may be asymmetrically disposed within the formed receiving slot 114. Of course, the number of the light sensors 40 is not limited to two, and the embodiment of the invention uses two light sensors 40 to achieve higher detection accuracy, and in other embodiments, the number of the light sensors may be 1 to reduce the complexity of the structure of the electronic device 100, or 3 to 4, and so on, to further improve the detection accuracy of the ambient light.

In some embodiments, the display 13 includes a display area 1311 and a non-display area 1312, the cover 11 includes a middle portion 111 covering the display area 1311 and a rim portion 113 connecting the middle portion 111, the rim portion 113 covers the non-display area 1312, and the light sensor 40 extends at least partially into the rim portion 113.

The display area 1311 is disposed corresponding to the middle portion 111, the non-display area 1312 and the edge portion 113, so that the cover plate 11 can be matched with the functional areas of the display 13, and cooperate with the functional areas, so that the display function of the electronic device 100 can be performed normally and orderly, and the edge portion 113 is opposite to the non-display area 1312, so that other light rays can be blocked, and the accuracy of detecting the light ray intensity by the light sensor 40 can be improved when the light sensor 40 at least partially extends into the edge portion.

In some embodiments, the ratio of the area of the display region 1311 to the cover plate 11 is greater than 90%. For example, the ratio of the area of the display region 1311 to the area of the cover plate 11 is a ratio of 95%, 96%, or the like.

Specifically, by setting the proportion of the display area 1311 and the cover plate 11, after the display screen 13 is attached to the cover plate 11, the display area 1311 can display the content effect in a large size area, so that not only is good user experience improved, but also the screen occupation ratio of the electronic device 100 is effectively increased, and a comprehensive screen effect is achieved. The non-display area 1312 can also be used to shield other components and metal traces underneath the display 13 to maintain the appearance of the product consistent. The non-display area 1312 may be printed with ink to increase the optical density of the display 13, so as to ensure the light-shielding effect and provide a good visual effect.

In some embodiments, the electronic device 100 includes the touch layer 12 disposed between the display 13 and the cover 11, and the light transmittances of the touch layer 12 and the cover 11 for visible light and infrared light are both greater than 90%.

Specifically, the touch layer 12 is mainly used for receiving an input signal generated when a user touches the touch layer 12 and transmitting the input signal to the circuit board for data processing, so as to obtain a specific position where the user touches the touch layer 12. The touch layer 12 and the display screen 13 can be bonded by using an In-Cell or On-Cell bonding technology, so that the weight of the display screen 13 can be effectively reduced, and the overall thickness of the display screen 13 can be reduced. In addition, the 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 screen 13 are prevented from being damaged by external force. The light transmittance of the 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 screen 13 to better display the content effect, but also beneficial to the infrared sensor 16 arranged below the display screen 13 to stably emit and receive infrared light, and ensures the normal operation of the infrared sensor 16.

Referring to fig. 4-7, in some embodiments, the electronic device 100 includes an infrared sensor 16 and a light blocking member 30 disposed below the display region 1311, the infrared sensor 16 includes an emitter 161 and a receiver 162, the emitter 161 is disposed below the non-display region 1312, the receiver 162 is disposed below the display region 1311, the emitter 161 is configured to emit infrared light, and the receiver 162 is configured to receive infrared light. The light blocking member 30 is disposed between the emitter 161 and the display region 1311, and the light blocking member 30 serves to block red light emitted from the emitter 161 from entering the display region 1311.

The emitter 161 is used to emit infrared light, which may be understood as, for example, the emitter 161 emitting infrared light through the non-display region 1312. The receiver 162 is used for receiving infrared light, for example, the receiver 162 receives infrared light through the display region 1311. The light blocking member 30 is disposed between the emitter 161 and the display region 1311, and the light blocking member 30 is used to block infrared light emitted from the emitter 161 from entering the display region 1311.

It is understood that the display 13 includes a display upper surface 131 and a display lower surface 132, and the display 13 is configured to emit light through the display upper surface 131. The display 13 is transparent so that infrared light from the emitter 161 is transmitted through the display 13 and, similarly, reflected infrared light is received by the receiver 162 through the display 13.

The transmitter 161 is used for transmitting infrared light, when the transmitted infrared light meets an obstacle in the detection direction, a part of the infrared light is reflected back to be received by the receiver 162, and the processor calculates the time from the transmission of the infrared light to the reflection of the infrared light, so that the distance between the electronic device 100 and the obstacle can be determined and corresponding adjustment can be made. In one example, when the user is answering or making a call, the electronic device 100 is close to the head, the transmitter 161 emits infrared light, the receiver 162 receives the infrared light reflected back by the head, the processor calculates the time from emission to reflection of the infrared light, and sends a corresponding instruction to control the screen to close the background light, and when the electronic device 100 is far away from the head, the processor calculates again according to the data fed back and sends an instruction to re-open the screen background light. Therefore, misoperation of the user is prevented, and the electric quantity of the mobile phone is saved.

Since the emitter 161 has a certain emission angle, even if the emitter 161 is located outside the display area 1311, there is no guarantee that infrared light emitted by the emitter 161 cannot enter the display area 1311. Therefore, the light blocking element 30 blocks the infrared light emitted by the emitter 161 from entering the display region 1311, and prevents the infrared light from adversely affecting the optoelectronic elements in the display region 1311. In one example, the light blocking member 30 is foam. Of course, the light blocking member 30 may be other non-light transmissive materials such as plastic.

In the electronic device 100, the receiver 162 serves as an input element of the electronic device 100, and the receiver 162 can receive an infrared signal and input the signal into the electronic device 100. The display 13 serves as an output element of the electronic device 100, and the display 13 can output display contents to the outside of the display 13 for a user to obtain corresponding information.

In summary, in the electronic device 100 according to the embodiment of the invention, the display 13 has the infrared sensor 16 disposed below the display 13, so as to further ensure that the electronic device 100 achieves a full-screen effect, and in addition, the orthographic projection of the emitter 161 of the infrared sensor 16 on the lower surface 132 of the display 13 is located outside the display area 1311 and the light blocking element 30 blocks infrared light from entering the display area 1311, so that the infrared light emitted by the emitter 161 can be prevented from affecting the operating stability of the TFT of the display area 1311, and thus the display 13 and the infrared sensor 16 can achieve their respective functions without interfering with each other.

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

In particular, an Organic Light-Emitting Diode (OLED) display screen has good Light transmittance and can transmit visible Light and infrared Light. Therefore, the OLED display screen does not influence the infrared sensor to emit and receive infrared light under the condition of showing the content effect. The display screen 13 may also be a Micro LED display screen, which also has good transmittance for visible light and infrared light. Of course, these display screens 13 are merely exemplary and embodiments of the present invention are not limited thereto.

Referring to fig. 4 and 5, in some embodiments, the light blocking member 30 is adhered and fixed at the connection between the display region 1311 and the non-display region 1312. In this way, the fixing manner of the light blocking member 30 is easily achieved, so that the electronic device 100 is easily manufactured. In one example, when the light blocking member 30 is fixed to the lower surface 132 of the display 13, a double-sided adhesive tape may be attached to one surface of the light blocking member 30, and then the light blocking member 30 may be fixedly attached to the joint between the display region 1311 and the non-display region 1312 by the double-sided adhesive tape.

Referring to fig. 6-9, in some embodiments, the infrared sensor 16 includes an encapsulation 163 encapsulating the emitter 161 and the receiver 162, and the light blocking member 30 is fixed on the encapsulation 163 and located between the emitter 161 and the receiver 162. In this manner, the light blocking member 30 is fixedly installed, so that the infrared sensor 16 and the light blocking member 30 are fitted with the display screen 13 as a whole.

In some embodiments, the light blocking member 30 is a soft material, and the light blocking member 30 abuts the lower surface 132. Thus, the light blocking element 30 has a better light blocking effect, and ensures that the infrared light emitted by the emitter 161 cannot enter the display region 1311. In addition, the matching structure of the infrared sensor 16 and the display screen 13 is more compact.

In some embodiments, the light blocking member 30 is a unitary structure with the encapsulant 163. In this way, the material of the light blocking member 30 is consistent with the material of the package body 163, and the light blocking member 30 can be formed at the same time of manufacturing the infrared sensor 16, so that the number of parts of the electronic device 100 can be saved to improve the assembly efficiency of the electronic device 100.

In some embodiments, the front projection of the receiver 162 on the lower surface 132 is located within the display area 1311, and the receiver 162 is configured to receive infrared light transmitted through the display area 1311. In this manner, the receiver 162 has a sufficient spatial arrangement. Of course, in some embodiments, the orthographic projection of receiver 162 on lower surface 132 may also be located at a position corresponding to non-display region 1312.

In some embodiments, the electronic device 100 further includes a first coating layer 14, the first coating layer 14 is coated on the bottom surface 132 and covers the emitter 161, the first coating layer 14 is used for transmitting infrared light and intercepting visible light, and the emitter 161 is used for transmitting infrared light through the first coating layer 14.

Specifically, the emitter 161 is usually mounted with a gap during the process of assembly, which results in a gap between the emitter 161 and other components, and visible light enters the gap to leak light. Therefore, in the direction in which the emitter 161 and the display 13 are stacked, the orthographic projection area of the first coating layer 14 on the lower surface 132 covers the orthographic projection area of the emitter 161 on the lower surface 132, so that the emitter 161 can be sufficiently shielded by the first coating layer 14 without affecting the normal operation of the emitter 161, and the effect that the emitter 161 is not visible when the electronic device 100 is viewed from the outside is achieved.

The first coating layer 14 transmits infrared light, so that when the transmitter 161 transmits infrared light outwards for detection, the intensity of the infrared light transmitted through the first coating layer 14 is attenuated to a small extent, or the attenuation degree does not affect the detection process, thereby ensuring the normal operation of the transmitter 161. The first coating layer 14 blocks visible light, so that the visible light cannot pass through the first coating layer 14, and the emitter 161 is visually shielded, thereby achieving the effect that the emitter 161 is not visible when the electronic device 100 is viewed from the outside.

In some embodiments, the infrared sensor 16 comprises a proximity sensor, the emitter 161 for emitting infrared light through the first coating layer 14 and the non-display area 1312, and the receiver 162 for receiving infrared light reflected by an object to detect the distance of the object from the display screen upper surface 131.

Specifically, in one example, when the user is answering or making a call, the electronic device 100 is close to the head, the transmitter 161 emits infrared light, the receiver 162 receives the reflected infrared light, the processor (not shown) calculates the time from the emission of the infrared light to the reflection of the infrared light, and emits a corresponding instruction to control the screen to close the backlight, and when the electronic device 100 is far away from the head, the processor performs calculation again according to the data fed back and emits an instruction to re-open the screen backlight. Therefore, misoperation of the user is prevented, and the electric quantity of the mobile phone is saved.

In certain embodiments, the first coating layer 14 comprises an IR ink having a transmittance of greater than 85% for infrared light and a transmittance of less than 6% for visible light, the IR ink being transparent to infrared light at a wavelength of 850nm to 940 nm.

Specifically, since the IR ink has a characteristic of low transmittance to visible light, the emitter 161 disposed under the first coating layer 14 is not observed based on the visual perception of human eyes when the electronic device 100 is viewed from the outside. Meanwhile, the IR printing ink has the characteristic of high light transmittance to infrared light, so that the emitter 161 can stably emit the infrared light, and the normal work of the emitter 161 is ensured.

In some embodiments, the transmitter 161 and receiver 162 are of a split construction.

In particular, since the transmitter 161 and the receiver 162 are separate structures, a compact arrangement or a dispersed arrangement may be selected when arranging the components, which is not only beneficial for the electronic device 100 to fully allocate the spatial positions of the components and apply the transmitter 161 and the receiver 162 with various shapes, but also beneficial for the transmitter 161 and the receiver 162 to provide possible positions for other components in the electronic device 100.

In one example, the split emitters 161 and receivers 162 are each disposed below a length edge of the non-display area 1312.

In another example, the split emitters 161 and receivers 162 are each disposed below a corner corresponding location of the non-display area 1312.

In yet another example, the split emitters 161 and receivers 162 are respectively disposed below both length edges of the non-display area 1312.

In some embodiments, the transmitter 161 and receiver 162 are of unitary construction.

Specifically, the transmitter 161 and the receiver 162 are of an integral structure, so that line connection between split structures can be omitted, the reduction of line process flow is facilitated, the production efficiency of products is improved, and the production cost is reduced.

In the infrared sensor 16, the transmitter 161 is located at a position corresponding to the non-display region 1312, and the receiver 162 is located at a position corresponding to the display region 1311.

The transmitter 161 and the receiver 162 of the entire structure are disposed at positions corresponding to the width edges of the non-display region 1312.

In some embodiments, the electronic device 100 further includes a second coating layer 15 coated on the bottom surface 132 and covering the receiver 162, wherein the second coating layer 15 is used for transmitting infrared light and intercepting visible light, and the receiver 162 is used for receiving infrared light through the display region 1311 and the second coating layer 15.

Specifically, the receiver 162 is usually mounted with a gap during the process of assembly, which results in a gap between the receiver 162 and other components, so that visible light enters from the gap and light leakage occurs. Therefore, in the direction in which the receiver 162 and the display 13 are stacked, the orthographic projection area of the second coating layer 15 on the lower surface 132 covers the orthographic projection area of the receiver 162 on the lower surface 132, so that the receiver 162 can be sufficiently shielded by the second coating layer 15 without affecting the normal operation of the receiver 162, and the effect that the receiver 162 is not visible when the electronic device 100 is viewed from the outside is achieved.

The second coating layer 15 may also be an IR ink, which has a characteristic of low transmittance of visible light, so that the receiver 162 disposed under the second coating layer 15 is not perceived by the human eye when the electronic device 100 is viewed from the outside. Meanwhile, since the IR ink has a characteristic of high transmittance to infrared light, the receiver 162 can stably receive infrared light, and normal operation of the receiver 162 is ensured.

In some embodiments, electronic device 100 further includes a buffer layer 17 covering lower surface 132 and avoiding infrared sensor 16.

Specifically, the buffer layer 17 is used to buffer impact force and prevent shock so as to protect the touch layer 12, the display screen 13 and the internal structure thereof, and prevent the display screen 13 from being damaged due to external impact. Cushioning layer 17 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. The purpose of avoiding the infrared sensor 16 during the process of providing the buffer layer 17 is to prevent the buffer layer 17 from blocking the signal received by the infrared sensor 16, so that the infrared sensor 16 is not affected during the process of receiving infrared light.

In some embodiments, electronic device 100 further includes a metal sheet 18 covering buffer layer 17 and avoiding infrared sensor 16.

Specifically, the metal sheet 18 is used for shielding electromagnetic interference and grounding, and has a function of diffusing temperature rise. The metal sheet 18 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, avoiding the infrared sensor 16 during the process of disposing the metal sheet 18 is to prevent the metal sheet 18 from blocking the signal received by the infrared sensor 16 so as not to affect the infrared sensor 16 during the process of receiving infrared light.

In another example, the processor (not shown) is configured to control the display 13 from the lock state to the unlock state according to the light signal sensed by the light sensor 40. This may facilitate the user to use the electronic device 100, improving the user experience. For example, when the user puts the electronic device 100 in a pocket, the electronic device 100 is in a screen-locking state, the light sensor 40 senses a weak light signal, when the user takes the electronic device 100 out of the pocket, the light sensor 40 senses a strong light signal, and at this time, the processor controls the display screen 13 to be unlocked so that the user can use the electronic device 100.

In yet another example, the processor (not shown) is configured to control the display 13 from the lock state to the unlock state according to the light signal sensed by the light sensor 40. This may facilitate the user to use the electronic device 100, improving the user experience. For example, when the user uses the electronic device 100 normally, the electronic device 100 is in an unlocked state, and the light sensor 40 senses that the intensity of the light signal is strong; when the user places the electronic device 100 in a pocket, the light sensor 40 senses that the intensity of the light signal is weak, and at this time, the processor controls the display 13 to lock the screen to prevent the electronic device 100 from being touched by mistake, so as to prevent adverse effects, such as mistaken call making by the electronic device 100.
