The specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may each refer to one or more of the same or different embodiments in accordance with the disclosure.
Hereinafter, a display apparatus and a method of controlling an image display viewing angle according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, the display device of the embodiment of the invention includes a light emitting module 1, an optical module and a display module 3.
The light emitting module 1 is capable of generating an initial light set for supplying backlight light to the display device for passing through the display module. Preferably, the light emitting module can provide sufficient brightness and uniformly distributed light.
The optical module is located in an irradiation area of the initial light set generated by the light-emitting module 1, and can at least form a first adjusting light set or a second adjusting light set. And the first illumination angle of the first adjusting light ray set is different from the second illumination angle of the second adjusting light ray set. In the embodiment of the present invention, the illumination angle refers to a projection angle of a light set generated by each module, that is, an included angle between two light rays with the largest included angle in the light set.
The display module 3 is located in an irradiation range of the adjusting light set formed by the optical module, and can form a display light set according to the image to be displayed, so that a viewer can perceive content corresponding to the image to be displayed. The display module can be a liquid crystal module and is used for enabling the arrangement direction of nematic liquid crystal molecules at each pixel position to be changed orderly under the action of an electric field and a magnetic field according to an image to be displayed, so that the liquid crystal molecules are controlled by a time sequence control technology to realize the modulation of light flux, bright and dark light rays or transmission and non-transmission of the light rays are presented, RGB pixel points are formed by colored films, and the imaging is displayed by utilizing the inertia of human eyes and the color mixing principle.
In the embodiment of the present invention, the first adjusting light set enables viewers in a first range to perceive the content corresponding to the image to be displayed, and the second adjusting light set enables viewers in a second range to perceive the content corresponding to the image to be displayed, where the first range is different from the second range.
For example, in one embodiment of the present invention, the first illumination angle of the first set of adjusted rays may be greater than the second illumination angle of the second set of adjusted rays. When shining the display module assembly through first adjustment light set, display device can treat the display image with wide visual angle display to the viewer that supplies in the first scope can see and treat the display image, and the viewer can adjust angle and the position of sitting of watching display device at will, improves viewer's comfort level and use experience. When the display module assembly is irradiated through the second irradiation angle of the second adjusting light set, the display device can display the image to be displayed at a narrow viewing angle, only the viewer in the second range can see the image to be displayed, and the viewer out of the second range cannot see any image, so that the effects of peeping prevention and light pollution reduction are achieved. For example, the first illumination angle of the first adjustment light set may be greater than 130 °, the second illumination angle of the second adjustment light set may be less than 60 °, and the viewer may generate the first adjustment light set or the second adjustment light set by setting the optical module, so that the switching between the wide viewing angle and the narrow viewing angle may be achieved without manually installing an additional privacy sheet outside the display device.
In the embodiment of the present invention, the optical module may be further configured to be a third adjusting light set which can be formed at different illumination angles of the first adjusting light set and the second adjusting light set according to actual requirements, and the third adjusting light set enables a viewer in a third range to perceive content corresponding to the image to be displayed, where the third range is different from both the first range and the second range.
In an embodiment of the present invention, the third illumination angle of the initial set of light generated by the light-emitting module 1 is smaller than or equal to or approximately equal to the second illumination angle, and in this case, the optical module may include the first optical element 2. Wherein the first optical component 2 may have at least a first state and a second state. In the first state, the initial set of light rays can form a first set of adjusted light rays after being transmitted through the first optical element 2 (the initial set of light rays is diffused into the first set of adjusted light rays), and in the second state, the first optical element 2 can form a second set of adjusted light rays after being transmitted through the initial set of light rays (the initial set of light rays is kept as the second set of adjusted light rays).
The first optical element 2 may be a controllable diffuser, and the principle of forming the first and second adjusted light sets using the controllable diffuser is: when the controllable diffusion sheet is electrified, the haze of the film of the controllable diffusion sheet can be controlled by changing the voltage. Where haze (haze) refers to the percentage of transmitted light intensity above an angle of 2.5 ° from the incident light to the total transmitted light intensity, and a greater haze means a decrease in film gloss and transparency, particularly image clarity, expressed as a percentage of the ratio of diffuse light flux to light flux through the material. Thus, by varying the haze of the film sheet of the controlled diffuser, the diffusion of the initial set of light rays through the controlled diffuser can be varied. When the haze of a film sheet of a controllable diffuser is increased, the degree of diffusion of the initial set of rays becomes greater, resulting in a larger angle of illumination for the adjusted set of rays; when the haze of a film sheet of a controllable diffuser is reduced, the degree of diffusion of the initial set of rays becomes smaller, resulting in a smaller illumination angle for the adjusted set of rays. Therefore, the illumination angle of the adjusted light set can be adjusted by controlling the haze of the film sheet of the controllable diffusion sheet.
When the controllable diffusion sheet is not electrified, the controllable diffusion sheet is in a first state, and the film sheet has higher haze. At this time, when the initial set of light rays transmit through the controllable diffusion sheet, as shown in fig. 2, the liquid crystal molecules in the controllable diffusion sheet are arranged and scattered in the non-energized state, so that the light rays incident into the controllable diffusion sheet are diffused, and therefore, the set of light rays transmitting through the controllable diffusion sheet can form a first adjusted set of light rays having a larger irradiation angle (i.e., a first irradiation angle). When the controllable diffuser is energized, the controllable diffuser is in a second state with a film sheet having low or even no haze. At this time, when the initial set of light rays transmit through the controllable diffusion sheet, as shown in fig. 3, the liquid crystal molecules in the controllable diffusion sheet are aligned in the energized state, and the light rays incident into the controllable diffusion sheet are not diffused, so that the set of light rays transmitting through the controllable diffusion sheet can form a second adjusted set of light rays having a smaller illumination angle (i.e., a second illumination angle).
As shown in fig. 4, in another embodiment of the present invention, the third illumination angle of the initial light set generated by the light emitting module 1 is larger than the second illumination angle, and in this case, the optical module includes a second optical element 4 in addition to the first optical element 2. The second optical assembly 4 may be located between the light emitting module 1 and the first optical assembly 2, and is configured to adjust the initial set of light rays having the third illumination angle to a transitional set of light rays having a fourth illumination angle smaller than the third illumination angle, and then irradiate the transitional set of light rays toward the first optical assembly 2.
In the embodiment of the present invention, the second optical assembly 4 may be a peep-proof sheet, the peep-proof sheet adopts a micro-louver optical technology, the irradiation angle of the light set passing through the peep-proof sheet can be changed, and the light set passing through the peep-proof sheet can be changed into a preset angle by using peep-proof sheets with different angles. For example, when it is desired to control the fourth illumination angle of the transition light ray set to be 7 °, the initial light ray set may be adjusted by using a 7 ° privacy sheet, and at this time, the fourth illumination angle of the transition light ray set is 7 °. At this time, the first illumination angle of the first adjusted light ray set may be set to 15 ° at minimum, and the second illumination angle of the second adjusted light ray set may be set to 7 ° at minimum. Compared with a 60-degree peeping prevention area in the prior art, the peeping prevention effect is better, and the secrecy of the image to be displayed is improved, so that the privacy of a user is protected.
Then, the transition light set is adjusted by the first optical assembly 2, so that the transition light set with the fourth illumination angle is diffused into the first adjustment light set with the first illumination angle in the first state by the first optical assembly 2, or the transition light set is kept as the second adjustment light set with the second illumination angle in the second state, and the peep-proof setting can be performed on the light-emitting module 1 emitting the initial light set with a large angle.
In the embodiment of the invention, the display equipment further comprises a detection module and a control module. The detection module is used for detecting input data, and the control module is used for processing the input data detected by the detection module. The control module can judge that if the input data meets the preset condition, the optical module is controlled to switch the first adjusting light ray set and the second adjusting light ray set. In the embodiment of the present invention, since the first optical element 2 is a controllable diffusion sheet, if the input data satisfies the predetermined condition, the controllable diffusion sheet can be controlled to be powered on, so as to switch the first adjusting light ray set and the second adjusting light ray set.
In an embodiment of the present invention, the detecting module further includes an input module, configured to detect operation data generated by operation of the operating body, and use the operation data as input data. At this time, the control module may switch the energization control of the controllable diffusion sheet according to the manual input data of the operation body (viewer). The preset condition can be first instruction data which is pre-stored in the electronic equipment and does not start peeping or second instruction data which starts peeping, and the control module can judge that the operation data is consistent with the first instruction data or the second instruction data. When the operation data generated by the operation of the operation body is matched with the first instruction data, the control module does not electrify the controllable diffusion sheet, and when the operation data generated by the operation of the operation body is matched with the second instruction data, the control module electrifies the controllable diffusion sheet. The operation data may be different input modes, for example, the operation data may be trigger signal data of different keys/combination keys, and when it is detected that the trigger signal data of the key/combination key matches the first instruction data (a preset trigger mode data of the key/combination key), the controllable diffusion sheet is not controlled to be powered on, so that the controllable diffusion sheet forms a first adjustment light ray set; when the trigger signal data of the key/combination key is matched with the second instruction data (the preset other trigger mode data of the key/combination key), the power-on of the controllable diffusion sheet is controlled, so that the controllable diffusion sheet forms a second adjusting light ray set. The operation data may be the same input mode, but the input time or the input times are different, for example, the operation data may be trigger signal time number data/multiple trigger signal time interval data of the same key/combination key, when the detected trigger signal time number data/multiple trigger signal time interval data matches with the first instruction data (preset trigger signal time number data/multiple trigger signal time interval data), the controllable diffusion sheet is not controlled to be powered on, so that the controllable diffusion sheet forms the first adjusting light ray set; and when the detected trigger signal time data/trigger signal time interval data is matched with second instruction data (preset other trigger signal time data/trigger signal time interval data), controlling the energization of the controllable diffusion sheet so that the controllable diffusion sheet forms a second adjusting light ray set.
In another embodiment of the present invention, the detection module further includes an acquisition module, and the acquisition module is configured to acquire image data within the first range or the second range and use the image data as input data, and at this time, the control module is capable of automatically switching the power-on control of the controllable diffusion sheet according to the image data acquired by the acquisition module.
Specifically, the control module may detect a face in the image data through face recognition, and then automatically switch the energization control of the controllable diffusion sheet according to the detected face. For example, when the number of detected faces is 1, the control module may determine that the viewer in front of the display device has only 1 person, and there is no possibility that the related content in the image to be displayed is perceived by other people, and therefore, the control module may not energize the controllable diffusion sheet, so that the image to be displayed may be perceived in the first range with the larger range. At the moment, the angle and the sitting posture of the display equipment can be adjusted at will by the viewer, and the comfort level and the use experience of the viewer are improved. When the number of the detected faces is larger than 1, the control module can judge that a viewer in front of the display device has a plurality of people and the possibility that the related content in the image to be displayed is sensed by other people exists, so that the control module can electrify the controllable diffusion sheet, only the viewer in a second range with a smaller range can see the image to be displayed, and the viewer outside the second range cannot see any image, thereby achieving the effect of peep prevention. For another example, when the number of detected faces is greater than 1, the detected faces may be continuously compared with faces prestored in the electronic device, and when the detected faces can be all matched with faces prestored in the electronic device, the control module may determine that all viewers are users, under this condition, the control module may not energize the controllable diffusion sheet, so that the image to be displayed may be perceived within a first range with a larger range, so that all viewers located within the first range can share image content, and convenience in use of the display device is improved. When at least one detected face cannot be matched with a face prestored in the electronic equipment, the control module can judge whether the viewer exists, under the condition, the control module can electrify the controllable diffusion sheet, only the viewer in a second range with a smaller range can see the image to be displayed, and the viewer out of the second range cannot see any image, so that the peeping prevention effect is achieved.
As shown in fig. 5, the present invention also provides a display method, including:
and S10, generating an initial light set by using the light emitting module.
S20, forming a first adjusted light set or a second adjusted light set by using the optical module located in the illumination area of the initial light set, wherein a first illumination angle of the first adjusted light set is different from a second illumination angle of the second adjusted light set.

The first adjusting light ray set enables a viewer in a first range to perceive content corresponding to the image to be displayed, the second adjusting light ray set enables the viewer in a second range to perceive content corresponding to the image to be displayed, and the first range is different from the second range.
Specifically, in the embodiment of the present invention, the minimum first illumination angle of the first adjusting light set may be set to 15 °, at this time, the display device may display the image to be displayed at a wide viewing angle, so that a viewer in the first range may see the image to be displayed, and the viewer may adjust an angle and a sitting posture of viewing the display device at will, so as to improve comfort and user experience of the viewer. The minimum second illumination angle of the second adjusting light set can be set to 7 °, at this time, the display device can display the image to be displayed at a narrow viewing angle, only the viewer in the second range can see the image to be displayed, and the viewer out of the second range cannot see any image, so that the peep-proof effect is achieved. Compared with a 60-degree peeping prevention area in the prior art, the peeping prevention effect is better, and the secrecy of the image to be displayed is improved, so that the privacy of a user is protected.
In an embodiment of the present invention, forming the first set of adjusting rays or the second set of adjusting rays comprises:
and S21, obtaining input data. The input data includes at least one of operation data generated by operation of an operation body and image data in a first range or a second range.
S22, judging whether the input data meet the preset conditions, and adjusting the initial light set generated by the light-emitting module into a first adjusting light set or a second adjusting light set according to the judgment result. Specifically, if the input data meets a predetermined condition, the initial ray set is adjusted to a second adjusted ray set; if the input data does not satisfy the predetermined condition, the initial ray set is adjusted to a first adjusted ray set.
In an embodiment of the present invention, when the input data includes operation data generated by an operation of an operator, the initial set of light rays generated by the light emitting module may be adjusted to the first adjusted set of light rays or the second adjusted set of light rays according to manual input data of the operator (viewer). The preset condition may be that the preset condition is first instruction data which does not start peeping or second instruction data which starts peeping, and is pre-stored in the electronic device, at this time, it may be determined that the operation data matches the first instruction data or the second instruction data, when the operation data generated by the operation of the operation body matches the first instruction data, the initial light set generated by the light-emitting module may be adjusted to a first adjustment light set, and when the operation data generated by the operation of the operation body matches the second instruction data, the initial light set generated by the light-emitting module may be adjusted to a second adjustment light set.
In another embodiment of the present invention, when the input data is image data in a first range or a second range, at least one face image in the image data may be determined, and then it is determined whether the face image satisfies a preset condition, and the initial light set generated by the light emitting module is adjusted to be the first adjustment light set or the second adjustment light set according to the determination result. For example, when the number of detected faces is 1, the initial light set generated by the light emitting module may be adjusted to a first adjusted light set; when the number of the detected faces is more than 1, the initial light set generated by the light-emitting module can be adjusted to be a second adjusted light set.
