Description

Technical Field

[0001] This application belongs to the field of terminal technology, specifically relating to a display screen, display method, device, electronic device, medium, and computer program. Background Technology

[0002] With the development of terminal technology, electronic devices are being used more and more frequently. In public places, the private information displayed on the screens of these devices, such as payment passwords, may be spied on by others, leading to information leaks.

[0003] Currently, privacy can be achieved by installing a privacy film with a louvered structure on the display screen of electronic devices. Specifically, the louvered structure blocks light from escaping from the sides of the display screen, preventing people around the screen from seeing the content displayed on it.

[0004] However, following the above method, a privacy screen protector needs to be installed on the display screen to achieve privacy protection, and the display screen with the privacy screen protector is always in a privacy protection state, which results in a relatively limited display mode. Summary of the Invention

[0005] The purpose of this application is to provide a display screen, display method, device, electronic device, medium, and computer program that can improve the display flexibility of the display screen while achieving the privacy protection effect.

[0006] In a first aspect, embodiments of this application provide a display screen, which may include: a color filter, a frame, and a display screen body, a cover plate, and a moving mechanism sequentially disposed on the frame; the display screen body and the cover plate are disposed opposite to each other, the color filter is located between the display screen body and the cover plate and connected to the moving mechanism, and the thickness of the color filter is less than the distance between the display screen body and the cover plate; wherein, the moving mechanism is used to drive the color filter to move and adjust the offset parameter of the filter unit in the color filter relative to the light-emitting pixel in the display screen body, so as to adjust the viewing angle of the display screen body, and the viewing angle of the display screen body is negatively correlated with the offset parameter.

[0007] Secondly, embodiments of this application provide a display device, including the display screen described in the first aspect.

[0008] Thirdly, embodiments of this application provide a display method executed by the display device described in the second aspect. The display method may include: under the condition of satisfying a first condition, increasing the offset parameter of the filter unit in the color filter of the display screen relative to the light-emitting pixel in the display screen body through a moving mechanism in the display screen, so as to reduce the viewing angle of the display screen body, wherein the viewing angle of the display screen body is negatively correlated with the offset parameter; wherein the first condition includes at least one of the following: receiving a user's privacy input; and the detected observation information indicating the presence of an observer.

[0009] Thirdly, embodiments of this application provide an electronic device including a processor and a memory, the memory storing programs or instructions executable on the processor, the programs or instructions, when executed by the processor, implementing the steps of the method described in the third aspect.

[0010] Fourthly, embodiments of this application provide a readable storage medium on which a program or instructions are stored, which, when executed by a processor, implement the steps of the method described in the third aspect.

[0011] Fifthly, embodiments of this application provide a chip, the chip including a processor and a communication interface, the communication interface being coupled to the processor, the processor being used to run programs or instructions to implement the method as described in the third aspect.

[0012] In a sixth aspect, embodiments of this application provide a computer program product stored in a storage medium, which is executed by at least one processor to implement the method described in the third aspect.

[0013] In this embodiment, since the display screen includes a moving mechanism connected to a color filter, the offset parameters, such as offset distance and offset angle, of the filter unit in the color filter relative to the light-emitting pixels in the display screen body can be adjusted via the moving mechanism. This allows for adjustment of the viewing angle of each light-emitting pixel in the display screen body. It is understood that the smaller the viewing angle of the display screen, the better the privacy protection effect. Therefore, the display screen provided in this embodiment can switch between privacy protection mode and normal display mode by moving the color filter, thus not only achieving privacy protection but also improving the display screen's display flexibility.

[0025] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0026] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0027] The following description, in conjunction with the accompanying drawings, details the display screen, display method, device, electronic device, medium, and computer program provided in the embodiments of this application through specific examples and application scenarios.

[0028] The display screen, display method, device, electronic device, medium, and computer program provided in the embodiments of this application can be applied to scenarios where electronic devices display information.

[0029] For example, the display method provided in this application embodiment is applied to scenarios where a display device is used in a public place or a private place.

[0030] For example, during user operation of the display device, the user can trigger a privacy input to increase the offset parameter of the filter unit in the color filter relative to the light-emitting pixels in the display body via a moving mechanism within the screen. This reduces the viewing angle of the display body, thus putting the screen in a privacy mode. In this way, the content displayed on the screen is prevented from being seen by others, thereby preventing content leakage.

[0031] For example, when a user uses a display device in a public place, if the display device detects an observer, it increases the offset parameter of the filter unit in the color filter relative to the light-emitting pixels in the display body via a moving mechanism. This reduces the viewing angle of the display body, thus putting the display in a privacy mode. In this way, it prevents others from seeing the content displayed on the screen, thereby preventing the leakage of the displayed content.

[0032] This application provides a display screen. Figure 1 A schematic diagram of the structure of the display screen provided in an embodiment of this application is shown, such as... Figure 1As shown, the display screen 100 provided in this embodiment may include: a color filter 10, a frame 20, and a display screen body 30, a cover plate 40, and a moving mechanism 50 sequentially disposed on the frame 20. The display screen body 30 and the cover plate 40 are disposed opposite to each other, the color filter 10 is located between the display screen body 30 and the cover plate 40 and is connected to the moving mechanism 50, and the thickness of the color filter 10 is less than the distance between the display screen body 30 and the cover plate 40.

[0033] The moving mechanism 50 can be used to move the color filter 10 and adjust the offset parameter of the filter unit 11 in the color filter 10 relative to the light-emitting pixel 31 in the display body 30, so as to adjust the viewing angle of the display body 30.

[0034] Among them, the viewing angle of the display body 50 is negatively correlated with the offset parameter.

[0035] In some embodiments of this application, the aforementioned color filter replaces the polarizer layer in the display screen of the related art to reduce the reflectivity of the display screen.

[0036] In some embodiments of this application, such as Figure 2 As shown, the color filter may include: a first substrate layer 12, a plurality of filter units embedded in the first substrate layer 12, and a first organic protective layer 13 covering the first substrate layer 12.

[0037] Each of the plurality of filter units can be any of the following: a red (R) filter unit, a green (G) filter unit, and a blue (B) filter unit.

[0038] In some embodiments of this application, such as Figure 2 As shown, the display screen body may include, from bottom to top, a second base layer 32, a light-emitting pixel layer 33, and a second organic protective layer 34. The second base layer 32 is connected to the bottom wall of the frame 10, and the first base layer 12 is disposed opposite to the second organic protective layer 34. The light-emitting pixel layer 33 includes a plurality of light-emitting pixels 31 arranged in an array. It should be noted that each of the above-mentioned multiple filter units corresponds to one light-emitting pixel, and different filter units correspond to different light-emitting pixels.

[0039] In some embodiments of this application, such as Figure 2 As shown, the second base layer 32 is connected to the bottom wall of the frame 20.

[0040] In some embodiments of this application, the light-emitting pixels can be active-matrix organic light-emitting diodes (AMOLED), organic light-emitting diodes (OLED), light-emitting diodes (LED), mini LEDs, or micro LEDs.

[0041] In some embodiments of this application, each of the plurality of light-emitting pixels can emit R light, G light, B light, or white (W) light, which can be determined according to actual usage requirements.

[0042] It should be noted that when the light-emitting pixels emit white light, the display body may also include a filter layer covering the light-emitting pixel layer to filter the white light into monochromatic light, such as R, B, or B light. In other words, the light entering the filter unit is already monochromatic, thus avoiding color crosstalk.

[0043] In some embodiments of this application, the layers in the display screen body are bonded together by adhesives. The first adhesive can be glue or other adhesive components.

[0044] Similarly, the layers in a color filter can also be bonded together using a first adhesive. The second adhesive can be glue or other bonding components.

[0045] In some embodiments of this application, the area of ​​the color filter is smaller than the area of ​​the display screen body, which ensures that the moving mechanism can drive the color filter to move.

[0046] In some embodiments of this application, such as Figure 1 As shown, the cover 40 can be attached to the top of the frame 20 via a third adhesive member 60. The third adhesive member 60 can be glue or double-sided tape.

[0047] In some embodiments of this application, the offset parameters may include at least one of the following: offset angle, circumferential offset distance, and axial offset distance.

[0048] In some embodiments of this application, such as Figure 3 As shown, the aforementioned offset angle can be the angle α between the geometric center of the filter unit 11 and the geometric center of the light-emitting pixel 31 corresponding to the filter unit 11.

[0049] In some embodiments of this application, the aforementioned offset angle can be the angle between the center point of the filter unit and the center point of the corresponding light-emitting pixel of the filter unit.

[0050] In some embodiments of this application, the axial offset distance between the light-emitting pixel and the filter unit can be represented by the spacing between the color filter and the display body.

[0051] In some embodiments of this application, the circumferential offset distance between the light-emitting pixel and the filter unit can be represented by the distance between the center line of the color filter and the center line of the display body. Alternatively, it can be represented by the distance between the center line of the light-emitting pixel and the center line of the filter unit. This application does not impose any limitations.

[0052] It should be noted that the offset parameter between the filter unit and the corresponding light-emitting pixel can characterize the degree to which the color filter blocks the light emitted by the light-emitting pixel. Specifically, the larger the offset parameter, the greater the degree to which the black substrate layer of the color filter blocks the light emitted by the light-emitting pixel, and thus the smaller the viewing angle of the light-emitting pixel.

[0053] For example, such as Figure 4A As shown, when the offset parameter between the filter unit 11 and the light-emitting pixel 31 is at its minimum, the viewing angle of the light-emitting pixel 31 is a1. It can be seen that, therefore, the user and other users located on the left and right sides of the display screen cannot view the content displayed on the display screen.

[0054] like Figure 4B As shown, when the color filter shifts to the left relative to the display screen body, the light emitted by the light-emitting pixel 31 to the right of the dotted line 01 is blocked by the black base layer, i.e. the first base layer. Therefore, the viewing angle of the light-emitting pixel 31 is a2, and a2 is less than a1. As a result, other users located on the left side of the display screen cannot view the content displayed on the display screen.

[0055] like Figure 4C As shown, when the color filter is offset upward relative to the display body, that is, when the distance between the color filter and the display body increases, the light emitted by the light-emitting pixel 31 located to the left of the dashed line 02 and to the right of the dashed line 03 is blocked by the black base layer, that is, the first base layer. Therefore, the viewing angle of the light-emitting pixel 31 is a3, and a3 is less than a1. As a result, users located on the left and right sides of the display cannot view the content displayed on the display.

[0056] In some embodiments of this application, the offset parameters are different, and the distance between the display body and the cover plate is also different.

[0057] Specifically, assuming the offset parameter is the first distance between the display body and the cover plate when the offset angle is the first distance, and the offset parameter is the second distance between the display body and the cover plate when the axial offset distance is the second distance, then: the first distance is less than the second distance.

[0058] For example, the first spacing can be 100 μm, and the second spacing can be 1.2 or 1.5 times the thickness of the color filter.

[0059] It is understandable that when the offset parameter is the axial offset distance, it will inevitably lead to an increase in the total thickness of the display screen. However, since the thickness of the color filter is relatively small, the increase in the total thickness of the display screen is only about 100μm. Therefore, the increase in the thickness of the display screen has little impact on display devices with an overall thickness of 8-10mm.

[0060] It should be noted that the above descriptions of the first spacing and the overall thickness are for illustrative purposes only and do not constitute a limitation on the embodiments of this application.

[0061] In some embodiments of this application, the type of offset parameter is determined by the movement mode of the moving mechanism. If the moving mechanism can move the color filter in a plane parallel to the display screen body, then the offset parameter is an offset angle or a circumferential offset distance.

[0062] If the moving mechanism can drive the color filter to move in a direction perpendicular to the display body, including directions away from or close to the display body, then the offset parameter can include the axial offset distance.

[0063] In some embodiments of this application, when the offset parameter is an offset angle or a circumferential offset distance, if the offset parameter increases, the viewing angle of the luminescent pixel in the opposite direction of the offset direction decreases, such as... Figure 4B The included angle a2 is shown. When the offset parameter is the axial offset distance, if the offset parameter increases, the viewing angle of the emitting pixel decreases proportionally in all directions, such as... Figure 4C The included angle a3 is shown.

[0064] In the display screen provided in this application embodiment, since the display screen includes a moving mechanism connected to a color filter, the offset parameters of the filter unit in the color filter relative to the light-emitting pixels in the display screen body, such as offset distance and offset angle, can be adjusted by the moving mechanism, thereby realizing the adjustment of the viewing angle of each light-emitting pixel in the display screen body. It is understood that the smaller the viewing angle of the display screen, the better the privacy protection effect of the display screen. Therefore, the display screen provided in this application embodiment can switch between privacy protection mode and normal display mode by moving the color filter, thus not only realizing privacy protection, but also improving the display flexibility of the display screen.

[0065] It should be noted that the moving mechanism may differ depending on the offset parameter. The following description uses offset angle or circumferential offset distance as the offset parameter (I) and axial offset distance as the offset parameter (II) as examples to illustrate the display screen provided in the embodiments of this application.

[0066] 1. The offset parameter is either the offset angle or the circumferential offset distance.

[0067] In some embodiments of this application, when the offset parameter is an offset angle or a circumferential offset distance, the moving mechanism may include... Figure 2 At least one circumferential moving component 51 is shown, which is disposed on the side wall of the frame 20, and at least one circumferential moving component 50 is connected to the color filter 10.

[0068] Among them, different circumferential moving components 51 can be used to drive the color filter 10 to move in different directions along the first plane, which is parallel to the display screen body 30.

[0069] In some embodiments of this application, the number of circumferential moving components and the relative positions of the circumferential moving components and the color filter are determined in relation to the privacy orientation of the display screen.

[0070] For example, suppose Figure 5 This is a top view of color filter 50.

[0071] 1) If the privacy protection direction of the display screen includes the X direction, then the number of circumferential moving components is 1, and the circumferential moving component 51-1 can be set on the side of the color filter 50 parallel to the Y axis. Thus, the circumferential moving component 51-1 can drive the color filter to move to the left along the X axis to achieve privacy protection for the right side area of ​​the display screen, or the circumferential moving component 51-1 can drive the color filter 50 to move to the right along the X axis to achieve privacy protection for the left side area of ​​the display screen.

[0072] 2) If the privacy protection direction of the display screen includes the Y direction, then the number of circumferential moving components is 1, and the circumferential moving component 51-2 can be set on the side of the color filter parallel to the X axis. Thus, the circumferential moving component 51-2 can drive the color filter to move to the left along the Y axis to achieve privacy protection of the lower area of ​​the display screen, or the circumferential moving component 51-2 can drive the color filter to move downward along the Y axis to achieve privacy protection of the upper area of ​​the display screen.

[0073] 3) If the privacy protection direction of the display screen includes the X direction and the Y direction, then the number of circumferential moving components is 2. The circumferential moving component 51-1 can be set on the side of the color filter parallel to the X axis, and the circumferential moving component 51-2 can be set on the side of the color filter parallel to the Y axis. Thus, privacy protection in the Y direction of the display screen is achieved by moving component 511, and privacy protection in the X direction of the display screen is achieved by moving component 51-2.

[0074] In essence, achieving privacy protection along the X-axis means preventing people located in the X direction of the display from peeping at the content shown on the screen. Similarly, achieving privacy protection along the Y-axis means preventing people located in the Y direction of the display from peeping at the content shown on the screen.

[0075] Thus, when the offset parameter is an offset angle or a circumferential offset distance, since at least one circumferential moving component can be provided between the color filter and the side wall of the frame, the color filter can be moved along at least one direction parallel to the display body by the at least one circumferential moving component, thereby achieving privacy protection of the display in at least one direction, which can improve the flexibility of privacy protection.

[0076] In some embodiments of this application, each of the circumferential moving components described above may include any one of the following:

[0077] Method 1: A telescopic motor and a first spring arranged symmetrically; Method 2: Two telescopic motors arranged symmetrically; Method 3: Two spool structures arranged symmetrically; Method 4: A spool structure and a second spring arranged symmetrically.

[0078] Methods 1 through 4 will be explained below.

[0079] Method 1: Each circumferential moving component includes a symmetrically arranged telescopic motor and a first spring.

[0080] In some embodiments of this application, the first spring may be a compression spring or a tension spring. It is understood that a compression spring shortens its length and stores elastic potential energy when subjected to force, while a tension spring extends its length and stores elastic potential energy when subjected to force.

[0081] In some embodiments of this application, a telescopic motor provides power for the movement of the color filter, and the first spring supports the color filter, ensuring that the color filter is stably parallel to the display screen body.

[0082] It is understandable that the extension and retraction states of the telescopic motor will differ depending on the first spring and when the first spring is not under force.

[0083] For example, taking a tension spring as the first spring, when the first spring is not under force, the telescopic motor is in the extended state, and the color filter is offset to the maximum distance from the first spring. When the telescopic motor retracts, the offset distance of the color filter gradually decreases until the color filter is directly opposite the display screen body. If the telescopic motor continues to retract, the color filter is offset in the direction of the telescopic motor, and the offset distance gradually increases.

[0084] For example, taking a tension spring as the first spring, when the first spring is not under force, the telescopic motor is in the retracted state, and the color filter is offset by the maximum distance in the direction of the telescopic motor. When the telescopic motor extends, the offset distance of the color filter gradually decreases until the color filter is directly opposite the display screen body. If the telescopic motor continues to extend, the color filter is offset by the direction of the first spring, and the offset distance gradually increases.

[0085] In some embodiments of this application, in mode 1, the extension length of the telescopic shaft of the telescopic motor is different, and the display mode of the display screen may be different.

[0086] For example, using the privacy orientation of the display screen as... Figure 5 Taking the X direction as an example: When the telescopic motor's extension shaft is retracted, the color filter is offset to the left relative to the display body, reaching its maximum offset distance, and the viewing angle on the right side of the display is minimized, placing the display in right-side privacy mode. When the extension shaft is extended by 50%, the color filter is directly opposite the display body, ideally aligned with the center line, and the offset distance is minimized, resulting in the maximum viewing angle and normal display mode. When the extension shaft is extended by 100%, the color filter is offset to the left relative to the display body, reaching its maximum offset distance, and the viewing angle on the left side of the display is minimized, placing the display in left-side privacy mode. For a description of privacy in the Y direction, please refer to the relevant description of privacy in the X direction.

[0087] Thus, when the circumferential moving component includes a symmetrically arranged telescopic motor and a first spring, privacy protection in two opposite directions of the display screen can be achieved through the cooperation of the telescopic motor and the first spring. This not only improves the flexibility of privacy protection but also simplifies the structure of the display screen.

[0088] Method 2: Each circumferential moving component includes two symmetrically arranged telescopic motors.

[0089] In some embodiments of this application, when the color filter is directly opposite the display screen body, that is, when the offset angle and horizontal offset distance are at their minimum, both of the above-mentioned telescopic motors extend by a certain size.

[0090] When the color filter needs to move toward one of the two telescopic motors, the first telescopic motor can retract at a first speed, and the other telescopic motor can extend at the same speed. Thus, the color filter can gradually move toward the direction of the first telescopic motor with the cooperation of the two telescopic motors.

[0091] Thus, by having two symmetrically arranged telescopic motors work together to move the color filter along the axis of these two motors, and by having the color filter experience less tension when the two motors stop extending or retracting, damage to the color filter can be avoided. Therefore, not only can the movement of the color filter be achieved, but the service life of the color filter can also be improved.

[0092] Method 3: Each circumferential moving component includes: two symmetrically arranged scroll structures.

[0093] In some embodiments of this application, the roller structure may include a motor and a winding rope, with the motor fixed to the side wall of the frame, one end of the winding rope wound around the output shaft of the motor, and the second end of the winding rope connected to the color filter.

[0094] In some embodiments of this application, for two symmetrically arranged scroll structures, assuming that these two scroll structures are scroll structure 1 and scroll structure 2 respectively, and scroll structure 1 and scroll structure 2 are arranged on the left and right sides of the color filter, then:

[0095] When privacy protection is needed on the left side of the display screen, the motor in the scroll structure 2 can rotate to wind up the rope, while the motor in the scroll structure 1 can rotate in the opposite direction to extend the rope. Thus, with the cooperation of the scroll structures 1 and 2, the color filter is moved to the right to reduce the viewing angle on the left side of the display screen, thereby achieving privacy protection on the left side. When privacy protection is needed on the right side of the display screen, the motors in the scroll structures 1 and 2 can interchange their rotation directions, thereby moving the color filter to the left to reduce the viewing angle on the right side of the display screen, thereby achieving privacy protection on the right side.

[0096] In some embodiments of this application, the motors in the two symmetrically arranged roller structures maintain the same rotational speed.

[0097] Thus, by cooperating between two symmetrically arranged scroll structures, the color filter can move along the line parallel to the connection between the two scroll structures. Therefore, the circumferential offset distance and offset angle between the filter unit in the color filter and the light-emitting pixel in the display body can be adjusted, thereby enabling precise adjustment of the viewing angle of the display body in this line direction. This allows the display to be privacy-protected in a specific direction.

[0098] Method 4: Each circumferential moving component includes a symmetrically arranged scroll structure and a second spring.

[0099] In some embodiments of this application, when the offset parameter is at its minimum, the reel structure applies a certain tension to the compression spring through the color filter, allowing the compression spring to extend by a certain dimension. If the reel structure continues to wind the rope, the offset parameter can gradually increase, and the extension dimension of the compression spring also increases accordingly. If the reel structure loosens the rope, such as when the motor rotates in the reverse direction, the compression spring can reset, thereby driving the color filter to move towards the compression spring. When the compression spring completes its reset, the offset parameter reaches its maximum again.

[0100] Thus, by using the combination of the compression spring and the roller structure to move the color filter along the line connecting the two, the circumferential offset distance and offset angle between the filter unit in the color filter and the light-emitting pixels in the display body can be adjusted. This allows for precise adjustment of the viewing angle of the display body along that line, thereby enabling privacy protection of the display in a specific direction.

[0101] In some embodiments of this application, in mode 1 and mode 2, when the circumferential moving component includes a telescopic motor and the number of circumferential moving components is multiple, each telescopic motor can be connected to the color filter through an elastic connector.

[0102] The elastic connector can be used to buffer the stress between the connected telescopic motor and the color filter, wherein the direction of the stress is perpendicular to the axis of the connected telescopic motor.

[0103] In some embodiments of this application, the elastic connector may include any of the following: a third spring, a sponge column, an elastic titanium alloy or soft rubber column, etc.

[0104] Therefore, when there are multiple telescopic motors, since these multiple telescopic motors are used to drive the color filter to move in different directions, there is an included angle between the output shafts of these multiple telescopic motors. As a result, when one telescopic motor drives the color filter to move, there will be stress at the connection between the color filter and the other telescopic motors in the direction of movement of the color filter, which may cause damage to the color filter. However, after setting an elastic connector at the connection, the elastic connector can buffer this stress, thereby improving the reliability and service life of the display screen.

[0105] II. The offset parameter is the axial offset distance.

[0106] In some embodiments of this application, when the aforementioned offset parameter includes an axial offset distance, such as Figure 6 As shown, the aforementioned moving mechanism may include at least two axial moving components 52 distributed circumferentially along the color filter 10. These at least two axial moving components 52 are disposed on the bottom wall of the frame 20 and are connected to the color filter 10; wherein the extension and retraction directions of the different axial moving components 52 are the same.

[0107] It is understood that, in the above two cases, the at least two axial moving components can drive the color filter to move away from or towards the display screen body.

[0108] In some embodiments of this application, the above-mentioned at least two axial moving components work synchronously to ensure that the color filter smoothly approaches or moves away from the display body.

[0109] In some embodiments of this application, a receiving groove for accommodating an axially moving component can be provided on the bottom wall of the frame. The axially moving component can be installed in the receiving groove. This can reduce the thickness of the display screen on the one hand, and ensure that the display screen can be displayed in normal display mode on the other hand, that is, achieve the minimum circumferential offset distance.

[0110] In some embodiments of this application, each of the above-mentioned axial movement components can be: a telescopic motor, a hydraulic lift, a pneumatic lift, a lead screw and slider, etc. It is understood that when the axial movement component is a lead screw and slider, the lead screw is fixed to the bottom wall of the frame, and the slider is connected to the color filter.

[0111] In some embodiments of this application, when each axial movement component is a telescopic motor, and at least two telescopic motors are in the retracted state, the color filter can be attached to the display screen body to achieve normal display of the display screen.

[0112] In some embodiments of this application, the above-mentioned at least two telescopic motors may include: 2 telescopic motors, 3 telescopic motors or 4 telescopic motors, and this application does not limit them.

[0113] In some embodiments of this application, in order to save power consumption, the above-mentioned at least two telescopic motors may include two telescopic motors.

[0114] Thus, by using at least two telescopic motors mounted on the bottom wall of the frame to move the color filter away from or towards the display screen body, the axial offset angle between the filter unit in the color filter and the light-emitting pixels in the display screen body can be adjusted. This allows for synchronous adjustment of the viewing angle of the display screen body in all directions, thereby achieving privacy protection for the display screen in all directions and further improving the privacy protection effect.

[0115] In some embodiments of this application, the display screen may further include at least one infrared sensor distributed circumferentially along the cover plate.

[0116] Among them, at least one infrared sensor can be used to sense observation information, which can be used to indicate whether there is an observer;

[0117] The aforementioned moving mechanism can be used to move the color filter according to the observation information, and adjust the offset parameter of the filter unit in the color filter relative to the light-emitting pixel in the display body, so as to adjust the viewing angle of the display body.

[0118] In some embodiments of this application, the at least one infrared sensor can be embedded on the surface of the cover plate facing the color filter. For example, at least one groove can be provided on the surface of the cover plate facing the color filter, and an infrared sensor can be provided in each groove.

[0119] In some embodiments of this application, the aforementioned at least one infrared sensor may be located between the cover plate and the frame. For example, at least one groove may be provided on the frame, and an infrared sensor may be disposed in each groove.

[0120] In some embodiments of this application, the at least one infrared sensor may include: one infrared sensor, two infrared sensors, three infrared sensors, or four infrared sensors.

[0121] For example, when the display includes an infrared sensor, the infrared sensor can be set in a first area near the cover plate, where the first area of ​​the cover plate corresponds to the front-facing camera.

[0122] For example, when the display includes four infrared sensors, these four infrared sensors are respectively located on the upper edge, lower edge, left edge, and right edge of the cover plate.

[0123] In some embodiments of this application, an infrared sensor can measure the observer's position information, and then the infrared sensor can transmit the position information to a display device, such as a processor in the display device, and then the processor can calculate the observer's observation direction, observation distance and observation angle based on the position information.

[0124] In some embodiments of this application, when the display screen includes multiple infrared sensors, such as four infrared sensors arranged along the upper, lower left, and right edges of the cover plate, the processor can use the left-side infrared sensor to measure whether there is an observer on the left side of the display screen, the right-side infrared sensor to measure whether there is an observer on the right side of the display screen, the lower-side infrared sensor to measure whether there is an observer on the lower side of the display screen, and the upper-side infrared sensor to measure whether there is an observer on the upper side of the display screen. Alternatively, the processor can comprehensively calculate based on the measurement data from these sensors to determine the observer's viewing angle, viewing direction, and viewing distance. This application does not impose any limitations.

[0125] Thus, since the display screen includes at least one infrared sensor distributed circumferentially along the cover plate, the presence of an observer can be detected by these sensors. This allows the moving mechanism to accurately move the color filter based on the observation information detected by the infrared sensors, thereby more accurately preventing observers from peeping at the content displayed on the screen and improving the anti-peeping reliability of the display screen.

[0126] In some embodiments of this application, the aforementioned moving mechanism can be specifically used to increase the offset parameter of the filter unit in the color filter relative to the light-emitting pixel in the display body when the observation information indicates that there is a spy, so as to reduce the viewing angle of the display body; or, the moving mechanism can be specifically used to decrease the offset parameter of the filter unit in the color filter relative to the light-emitting pixel in the display body when the observation information indicates that there is no spy, so as to increase the viewing angle of the display body.

[0127] It is understandable that when the observation information indicates that there is no observer, if the viewing angle of the display screen has reached its maximum, that is, the display screen is in normal display state, the moving mechanism keeps the position of the color filter unchanged in order to keep the viewing angle of the display screen unchanged.

[0128] In some embodiments of this application, when the offset parameter is an offset angle, the observation information may include at least one of the following: observation angle, observation direction, and observation distance. The movement direction of the color filter is opposite to the observation direction, and the movement distance of the color filter is determined by at least one of the observation angle and the observation distance. The movement distance of the color filter is positively correlated with both the observation angle and the observation distance.

[0129] In some embodiments of this application, the observation distance can be the distance between the observer's position and the center of the display screen, or the distance between the observer's position and the infrared sensor.

[0130] In some embodiments of this application, the viewing angle can be the angle between the observer's position and the center line of the display screen.

[0131] In some embodiments of this application, the offset parameter is the offset distance, and the above observation information may include at least one of the following: observation angle, observation distance, the movement distance of the color filter is determined by the observation information, and the movement distance is positively correlated with the observation information.

[0132] In some embodiments of this application, the above embodiments are illustrated by taking LED, OLED or AMOLED as examples of display screen bodies. In actual implementation, the display screen body can also be an LED display screen.

[0133] This application embodiment also provides a display device, which may include... Figures 1 to 6 The display screen shown.

[0134] In the display device provided in this application embodiment, since the display screen of the display device includes a moving mechanism connected to a color filter, the offset parameters of the filter unit in the color filter relative to the light-emitting pixels in the display screen body, such as offset distance and offset angle, can be adjusted by the moving mechanism, thereby realizing the adjustment of the viewing angle of each light-emitting pixel in the display screen body. It is understood that the smaller the viewing angle of the display screen, the better the privacy protection effect of the display screen. Therefore, the display screen provided in this application embodiment can switch between privacy protection mode and normal display mode by moving the color filter, thus not only realizing privacy protection, but also improving the display flexibility of the display screen.

[0135] This application also provides a display method. Figure 7 This illustration shows a schematic flowchart of a display method provided in an embodiment of this application. This method can be executed by the display device described in the above embodiments, such as... Figure 7 As shown, the display method may include steps 700 and 701.

[0136] Step 700: The display device determines whether the first condition is met.

[0137] Step 701: When the first condition is met, the display device increases the offset parameter of the filter unit in the color filter of the display screen relative to the light-emitting pixel in the display screen body through the moving mechanism in the display screen, so as to reduce the viewing angle of the display screen body.

[0138] Among them, the viewing angle of the display screen itself is negatively correlated with the offset parameter;

[0139] The first condition may include at least one of the following: Condition 1: The display device receives user input; Condition 2: The observation information detected by the display device indicates the presence of an observer.

[0140] In some embodiments of this application, the above-mentioned privacy input can be used to trigger the display device to enable the privacy function.

[0141] In some embodiments of this application, when the first condition is condition 1, the display device can detect the observation information by a detection element before executing step 701.

[0142] The aforementioned detection element may include any one of the following: at least one infrared sensor in the display screen, or a front-facing camera in the display device.

[0143] For example, the display device can capture images using a front-facing camera, thereby allowing the display device to determine observation information based on the images.

[0144] For example, a display device can determine observation information based on information such as the number of faces, face size, and face position in an image.

[0145] It is understood that the description of information detected and observed through infrared sensors can be found in the relevant description in the above-mentioned display screen embodiment.

[0146] It should be noted that the observation information indicating the presence of an observer can include: if the infrared sensor detects other users besides the user, it indicates the presence of an observer, i.e., other users; or, the image captured by the front-facing camera includes facial images of people other than the user.

[0147] In the display method provided in this application embodiment, since the offset parameter of the filter unit in the color filter relative to the light-emitting pixel in the display body can be increased by the moving mechanism when the first condition is met, the viewing angle of the display body can be reduced. That is, the privacy of the display device can be achieved by reducing the viewing angle, thus improving the privacy flexibility.

[0148] In some embodiments of this application, the "increasing the offset parameter of the filter unit in the color filter of the display screen relative to the light-emitting pixel in the display screen body by means of the moving mechanism in the display screen" in step 701 above can be achieved by the following step A.

[0149] Step A: When the observation information indicates that there is an observer, the display device moves the color filter through the moving mechanism according to the observation information, so as to increase the offset parameter of the filter unit in the color filter relative to the light-emitting pixel in the display body.

[0150] The observation information may include at least one of the following: observation distance, observation angle, and observation direction.

[0151] In some embodiments of this application, the offset parameter may include at least one of the following: circumferential offset distance, offset angle, and axial offset distance.

[0152] Thus, when an observer is detected, the color filter can be moved by a moving mechanism based on at least one of the observer's observation distance, observation angle, and observation direction. This ensures that the observer cannot see the content displayed on the screen after the color filter is moved, thereby improving the accuracy of privacy protection.

[0153] In some embodiments of this application, the above observation information may include the observation angle or the observation distance; step A above can be implemented by step A1 below.

[0154] Step A1: When the observation information indicates that there is an observer, the display device moves the color filter a first distance in the first direction through the moving mechanism to increase the offset parameter of the filter unit in the color filter relative to the light-emitting pixel in the display body.

[0155] Among them, the first distance is positively correlated with the observed information, and the first direction is any one of the following: the direction away from the display screen body, or the direction parallel to the display screen body.

[0156] It can be understood that when the first direction is away from the display screen body, the above offset parameter is: axial offset distance. When the first direction is parallel to the display screen body, the above offset parameter is: offset angle or circumferential offset distance.

[0157] In some embodiments of this application, the moving mechanism is different, and the first direction described above is also different.

[0158] For example, when the moving mechanism is at least one circumferential moving component, the first direction is parallel to the display body; when the moving mechanism is at least two axial moving components, the first direction is away from the display body.

[0159] In some embodiments of this application, when the moving mechanism includes at least one horizontal moving component, the observation information may also include the observation direction. The first direction is opposite to the observation direction.

[0160] Thus, when an observer is detected, the moving mechanism drives the color filter to move in a direction parallel to the display screen body or in a direction away from the display screen body, which can reduce the viewing angle of the display screen body, thereby achieving privacy protection for the display screen and improving privacy protection flexibility.

[0161] It is understandable that since privacy is achieved by blocking part of the light from the light-emitting pixels in the display body through the first base layer in the color filter, the brightness of the display at the normal viewing angle may decrease after reducing the viewing angle of the display body. However, since the light-emitting pixels are not completely blocked, the resolution of the display remains unchanged.

[0162] In some embodiments of this application, after step 701 described above, the display method provided in the embodiments of this application may further include step 702.

[0163] Step 702: The display device increases the brightness of the screen.

[0164] In some embodiments of this application, the electronic device can increase the brightness of the display screen according to the viewing angle of the display screen.

[0165] For example, the smaller the viewing angle, the greater the increase in the display's brightness.

[0166] Thus, by reducing the viewing angle of the display screen, the brightness reduction caused by the color filter blocking some of the light from the light-emitting pixels can be compensated by increasing the brightness of the display screen, thereby improving the display effect.

[0167] In some embodiments of this application, after step 701 above, the display method provided in the embodiments of this application may further include step 703 below.

[0168] Step 703: If the second condition is met, the offset parameter of the filter unit in the color filter relative to the light-emitting pixel in the display body is reduced by the moving mechanism to increase the viewing angle of the display body.

[0169] The second condition may include at least one of the following: receiving the user's anti-peeping cancellation input; or the detected observation information indicating that there is no observer.

[0170] In some embodiments of this application, the aforementioned anti-spy cancellation input is used to trigger the display device to disable the anti-spy function.

[0171] In some embodiments of this application, the display device can increase the viewing angle of the display screen body to the maximum value in order to achieve normal display.

[0172] It is understandable that step 703 can also be referred to as the reset operation of the color filter.

[0173] It should be noted that when the display screen has its maximum viewing angle, the first substrate layer in the color filter does not block the light from the light-emitting pixels, so there is no loss of display screen brightness.

[0174] Thus, when the display device receives the user's privacy cancellation input or when the observation information indicates that there is no observer, it can move the color filter through the moving mechanism to reduce the offset parameter between the filter unit and the light-emitting pixel, thereby increasing the viewing angle of the display screen and improving the display angle to achieve normal display.

[0175] The display device in this application embodiment can be an electronic device or a component within an electronic device, such as an integrated circuit or a chip. The electronic device can be a terminal or other devices besides a terminal. For example, the electronic device can be a mobile phone, tablet computer, laptop computer, PDA, in-vehicle electronic device, mobile internet device (MID), augmented reality (AR) / virtual reality (VR) device, robot, wearable device, ultra-mobile personal computer (UMPC), netbook, or personal digital assistant (PDA), etc., and can also be a personal computer (PC), television (TV), ATM, or self-service machine, etc. This application embodiment does not specifically limit the specific type of device.

[0177] The display device provided in this application embodiment can achieve... Figures 1 to 6 The various processes implemented in the method embodiments achieve the same technical effect, and will not be described again here to avoid repetition.

[0178] Optionally, such as Figure 8 As shown, this application embodiment also provides an electronic device 800, including a processor 801 and a memory 802. The memory 802 stores a program or instructions that can run on the processor 801. When the program or instructions are executed by the processor 801, they implement the various steps of the above-described display device method embodiment and can achieve the same technical effect. To avoid repetition, they will not be described again here.

[0179] It should be noted that the electronic devices in the embodiments of this application include the aforementioned mobile electronic devices and non-mobile electronic devices.

[0180] Figure 9 A schematic diagram of the hardware structure of an electronic device provided in this application embodiment.

[0181] The electronic device 1500 includes, but is not limited to, components such as: radio frequency unit 1501, network module 1502, audio output unit 1503, input unit 1504, sensor 1505, display unit 1506, user input unit 1507, interface unit 1508, memory 1509, and processor 1510.

[0182] Those skilled in the art will understand that the electronic device 1500 may also include a power supply (such as a battery) for supplying power to various components. The power supply may be logically connected to the processor 1510 through a power management system, thereby enabling functions such as managing charging, discharging, and power consumption through the power management system. Figure 9 The electronic device structure shown does not constitute a limitation on the electronic device. The electronic device may include more or fewer components than shown, or combine certain components, or have different component arrangements, which will not be elaborated here.

[0183] The processor 1510 can, under the condition of satisfying the first condition, increase the offset parameter of the filter unit in the color filter in the display screen relative to the light-emitting pixel in the display screen body through the moving mechanism in the display screen, so as to reduce the viewing angle of the display screen body. The viewing angle of the display screen body is negatively correlated with the offset parameter.

[0184] The first condition may include at least one of the following:

[0185] Received user's privacy input;

[0186] The detected observation information indicates the presence of an observer.

[0187] In some embodiments of this application, the processor 1510 can be specifically used to increase the offset parameter of the filter unit in the color filter of the display screen relative to the light-emitting pixels in the display screen body through a moving mechanism in the display screen, which may include:

[0188] When the observation information indicates the presence of an observer, the color filter is moved by the moving mechanism according to the observation information, so as to increase the offset parameter of the filter unit in the color filter relative to the light-emitting pixel in the display body.

[0189] The observation information may include at least one of the following: observation distance, observation angle, and observation direction.

[0191] The processor 1510 can be used to move the color filter a first distance in a first direction via a moving mechanism, so as to increase the offset parameter of the filter unit in the color filter relative to the light-emitting pixel in the display body.

[0192] Among them, the first distance is positively correlated with the observed information, and the first direction can be any of the following: the direction away from the display screen body, or the direction parallel to the display screen body.

[0193] In some embodiments of this application, the processor 1510 may specifically be used to detect observation information via a front-facing camera or at least one infrared sensor in an electronic device before increasing the offset parameter of the filter unit in the color filter of the display screen relative to the light-emitting pixels in the display body of the display screen via a moving mechanism in the display screen.

[0194] In some embodiments of this application, the display unit 1506 may be used to increase the brightness of the display screen after the processing unit 1510 reduces the viewing angle of the display screen body.

[0195] In some embodiments of this application, the processing unit 1510 may also be used to, after reducing the viewing angle of the display body, reduce the offset parameter of the filter unit in the color filter relative to the light-emitting pixel in the display body by means of a moving mechanism, thereby increasing the viewing angle of the display body, provided that a second condition is met; wherein the second condition may include at least one of the following: receiving a user's anti-peeping cancellation input; or the detected observation information indicating that there is no observer.

[0196] In the electronic device provided in this application embodiment, since the offset parameter of the filter unit in the color filter relative to the light-emitting pixel in the display screen can be increased by the moving mechanism when the first condition is met, the viewing angle of the display screen body can be reduced. In other words, the privacy protection of the electronic device can be achieved by reducing the viewing angle, thus improving the privacy protection flexibility.
