[0002] With the development of terminal technology, the frequency of use of electronic devices is increasing. When using electronic devices in public places, private content displayed on the display screen of the electronic device, such as payment passwords, may be peeped by others, resulting in information leakage.

[0003] At present, anti-peeping can be achieved by installing an anti-peeping film with a louver structure layer on the display screen of an electronic device. Specifically, the louver structure can block light from emitting from the side of the display screen, so that people around the display screen cannot see the content displayed on the display screen.

[0004] However, according to the above method, since an anti-peeping film needs to be installed on the display screen to achieve the anti-peeping of the display screen, and the display screen with the anti-peeping film is always in the anti-peeping state, the display mode of the display screen is relatively simple. Summary of the invention

[0007] In a second aspect, an embodiment of the present application provides a display device, comprising the display screen described in the first aspect.

[0008] In a third aspect, an embodiment of the present application provides a display method, which is executed by the display device described in the second aspect. The display method may include: when a first condition is met, increasing, through a moving mechanism in the display screen, an offset parameter of a filter unit in a color filter in the display screen relative to a light-emitting pixel in a display screen body in the display screen to reduce a viewing angle of the display screen body, and 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 an anti-peep input from a user; and the detected observation information indicates that there is an observer.

It can be understood that the smaller the viewing angle of the display screen, the better the anti-peeping effect of the display screen. Therefore, the display screen provided in the embodiment of the present application can switch between the anti-peeping mode and the normal display mode by moving the color filter, so that not only anti-peeping can be achieved, but also the display flexibility of the display screen can be improved.

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0026] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0027] The following, in conjunction with the accompanying drawings, describes in detail the display screen, display method, device, electronic device, medium and computer program provided in the embodiments of the present application through specific embodiments and their application scenarios.

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

[0029] Exemplarily, the display method provided in the embodiments of the present application is applied to a scenario where a display device is used in a public place or a private place.

[0030] For example, when a user is using a display device, the user can trigger the display device to increase the offset parameter of the filter unit in the color filter in the display screen relative to the luminous pixel in the display screen body in the display screen through the anti-peep input, so as to reduce the viewing angle of the display screen body, thereby putting the display screen in an anti-peep state. In this way, it is possible to prevent others from seeing the content displayed on the display screen of the display device, thereby preventing the content displayed on the display screen from being leaked.

[0031] For example, when a user uses a display device in a public place, if the observation information detected by the display device indicates that there is an observer, the display device increases 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 in the display screen through the moving mechanism in the display screen to reduce the viewing angle of the display screen body, thereby putting the display screen in an anti-peeping state. In this way, it is possible to prevent others from seeing the content displayed on the display screen of the display device, thereby preventing the content displayed on the display screen from being leaked.

[0032] The embodiment of the present application provides a display screen, Figure 1 The structure diagram of the display screen provided in the embodiment of the present application is shown as follows: Figure 1As shown, the display screen 100 provided in the embodiment of the present application 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 arranged on the frame 20. The display screen body 30 and the cover plate 40 are arranged 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 drive the color filter 10 to move, and adjust the offset parameters of the filter unit 11 in the color filter 10 relative to the light-emitting pixel 31 in the display screen body 30 to adjust the viewing angle of the display screen body 30 .

[0034] The viewing angle of the display screen body 50 is negatively correlated with the offset parameter.

[0035] In some embodiments of the present application, the 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 the present application, Figure 2 As shown, the color filter may include: a first base layer 12 , a plurality of filter units embedded on the first base layer 12 , and a first organic protective layer 13 covering the first base layer 12 .

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

[0038] In some embodiments of the present application, Figure 2 As shown, the display screen body may include: a second substrate layer 32, a light-emitting pixel layer 33, and a second organic protective layer 34 arranged in sequence from bottom to top, the second substrate layer 32 is connected to the bottom wall of the frame body 10, the first substrate layer 12 and the second organic protective layer 34 are arranged opposite to each other, and the light-emitting pixel layer 33 includes a plurality of light-emitting pixels 31 distributed in an array. It should be noted that each of the plurality of light-filtering units corresponds to a light-emitting pixel, and different light-filtering units correspond to different light-emitting pixels.

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

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

[0041] In some embodiments of the present application, each of the above-mentioned multiple light-emitting pixels can emit R light, G light, B light, and white (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 screen body may further include a filter layer covering the light-emitting pixel layer, so as to filter the white light into monochromatic light, such as R, B or B light, through the filter layer. In other words, the light entering the filter unit is already monochromatic light, so cross-color can be avoided.

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

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

[0045] In some embodiments of the present application, the area of ​​the color filter is smaller than the area of ​​the display screen body, so that it can be ensured that the moving mechanism can drive the color filter to move.

[0046] In some embodiments of the present application, Figure 1 As shown, the cover body 40 can be covered on the top of the frame body 20 through the third adhesive member 60. The third adhesive member 60 can be glue or double-sided tape.

[0047] In some embodiments of the present application, the above-mentioned offset parameter may include at least one of the following: an offset angle, a circumferential offset distance, and an axial offset distance.

[0048] In some embodiments of the present application, Figure 3 As shown, the above-mentioned offset angle may 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 the present application, the above-mentioned offset angle may be the angle between the center point of the filter unit and the center point of the luminescent pixel corresponding to the filter unit.

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

[0051] In some embodiments of the present 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 screen body. Or 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 is not limited.

[0052] It should be noted that the offset parameter between the filter unit and the corresponding luminescent pixel can characterize the degree of shielding of the color filter on the light emitted by the luminescent pixel. The larger the offset parameter, the higher the degree of shielding of the black base layer of the color filter on the light emitted by the luminescent pixel, and thus the smaller the viewing angle of the luminescent pixel.

[0053] For example, Figure 4A As shown, when the offset parameter between the filter unit 11 and the luminous pixel 31 is the smallest, the viewing angle of the luminous pixel 31 is a1. It can be seen that the user and other users 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 is offset to the left relative to the display screen body, the light emitted by the luminous pixel 31 on the right side of the dotted line 01 is blocked by the black base layer, i.e., the first base layer. Therefore, the viewing angle of the luminous pixel 31 is a2, and a2 is smaller than a1, so that other users 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 screen body, that is, the distance between the color filter and the display screen body increases, since the light emitted by the luminous pixel 31 located on the left side of the dotted line 02 and on the right side of the dotted line 03 is blocked by the black base layer, that is, the first base layer, the viewing angle of the luminous pixel 31 is a3, and a3 is smaller than a1, so that users on the left and right sides of the display screen cannot view the content displayed on the display screen.

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

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

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

[0059] It can be understood that when the offset parameter is the axial offset distance, the total thickness of the display screen will inevitably increase. However, since the thickness of the color filter is relatively small, the increase in the total thickness of the display screen is about 100μm, so the increase in the thickness of the display screen has little effect on the display device with a thickness of 8-10mm.

[0060] It should be noted that the above description of the first spacing and the thickness of the whole device is for illustration only and does not constitute a limitation on the embodiments of the present application.

[0061] In some embodiments of the present application, the type of the offset parameter is determined by the moving mode of the moving mechanism. If the moving mechanism can drive the color filter to move in a plane parallel to the display screen body, 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 screen body, including a direction away from or close to the display screen body, the offset parameter may include an axial offset distance.

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

[0064] In the display screen provided in the embodiment of the present application, since the display screen includes a moving mechanism connected to the color filter, the offset parameters of the filter unit in the color filter relative to the luminous pixels in the display screen body, such as the offset distance and the offset angle, can be adjusted by the moving mechanism, so that the viewing angle of each luminous pixel in the display screen body can be adjusted. It can be understood that the smaller the viewing angle of the display screen, the better the anti-peeping effect of the display screen. Therefore, the display screen provided in the embodiment of the present application can switch between the anti-peeping mode and the normal display mode by moving the color filter, so that not only anti-peeping can be achieved, but also the display flexibility of the display screen can be improved.

[0065] It should be noted that the moving mechanism may be different if the offset parameters are different. The display screen provided in the embodiment of the present application is described below by taking the offset parameter as the offset angle or the circumferential offset distance (I) and the offset parameter as the axial offset distance (II) as examples.

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

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

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

[0069] In some embodiments of the present application, the number of circumferentially movable components and the relative positions of the circumferentially movable components and the color filter are determined by the anti-peeping direction of the display screen.

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

[0071] 1) If the anti-peeping direction of the display screen includes the X direction, the number of the circumferentially movable components is 1, and the circumferentially movable component 51-1 can be set on the side of the color filter 50 parallel to the Y axis, so that the circumferentially movable component 51-1 can drive the color filter to move leftward along the X axis to achieve anti-peeping of the right area of ​​the display screen, or the circumferentially movable component 51-1 can drive the color filter 50 to move rightward along the X axis to achieve anti-peeping of the left area of ​​the display screen.

[0072] 2) If the anti-peeping direction of the display screen includes the Y direction, the number of circumferentially movable components is 1, and the circumferentially movable component 51-2 can be set on the edge of the color filter parallel to the X-axis, so that the circumferentially movable component 51-2 can drive the color filter to move to the left along the Y-axis to achieve anti-peeping in the lower area of ​​the display screen, or the circumferentially movable component 51-2 can drive the color filter to move downward along the Y-axis to achieve anti-peeping in the upper area of ​​the display screen.

[0073] 3) If the anti-peeping direction of the display screen includes the X direction and the Y direction, the number of circumferential moving components is 2, and 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, so that the anti-peeping of the display screen in the Y direction is achieved by the moving component 511, and the anti-peeping of the display screen in the X direction is achieved by the moving component 51-2.

[0074] It can be understood that implementing anti-peeping in the X-axis direction means: preventing people located in the X direction of the display screen from peeping at the content displayed on the display screen. Similarly, implementing anti-peeping in the Y-axis direction means: preventing people located in the Y direction of the display screen from peeping at the content displayed on the display screen.

[0075] In this way, when the offset parameter is an offset angle or a circumferential offset distance, since at least one circumferentially movable component can be set between the color filter and the side wall of the frame, the color filter can be driven by the at least one circumferentially movable component to move in at least one direction parallel to the display screen body, thereby realizing anti-peeping of the display screen in at least one direction, which can improve the anti-peeping flexibility.

[0076] In some embodiments of the present application, each of the above-mentioned circumferential moving components may include any of the following:

[0077] Method 1: a symmetrically arranged telescopic motor and a first spring, Method 2: two symmetrically arranged telescopic motors, Method 3: two symmetrically arranged reel structures, Method 4: a symmetrically arranged reel structure and a second spring.

[0078] Methods 1 to 4 are described below respectively.

[0079] Mode 1: Each circumferential moving assembly includes a symmetrically arranged telescopic motor and a first spring

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

[0081] In some embodiments of the present application, the telescopic motor is used to provide power for the movement of the color filter, and the first spring is used to support the color filter so that the color filter can be stably parallel to the display screen body.

[0082] It can be understood that if the first spring is different and the first spring is not subjected to force, the telescopic state of the telescopic motor will also be different.

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

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

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

[0086] For example, the anti-peeping direction of the display screen is Figure 5 Take the X direction as an example. When the telescopic shaft of the telescopic motor is in the retracted state, the color filter is offset to the left relative to the display body, and the offset distance reaches the maximum, the viewing angle on the right side of the display is minimized, and the display is in the right anti-peeping display mode; when the telescopic shaft of the telescopic motor is extended by 50%, the color filter is directly opposite to the display body, such as the center line is aligned, and the offset distance reaches the minimum, the viewing angle of the display is maximum, and the display is in the normal display mode; when the telescopic shaft of the telescopic motor is extended by 100%, the color filter is offset to the left relative to the display body, and the offset distance reaches the maximum, the viewing angle on the left side of the display is minimized, and the display is in the left anti-peeping display mode. For the description of anti-peeping in the Y direction, refer to the relevant description of anti-peeping in the X direction.

[0087] In this way, when the circumferential moving component includes a symmetrically arranged telescopic motor and a first spring, since the anti-peeping function of the display screen in two opposite directions can be achieved through the cooperation between the telescopic motor and the first spring, it can not only improve the anti-peeping flexibility but also simplify the structure of the display screen.

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

[0089] In some embodiments of the present application, when the color filter is directly opposite to the display screen body, that is, when the offset angle and the horizontal offset distance are the smallest, the two telescopic motors are both extended to a certain size.

[0090] When the color filter needs to move toward one of the two telescopic motors, the telescopic motor can be retracted at a first speed, and the other telescopic motor can be extended at the same speed, so that the color filter can gradually move toward the direction of the telescopic motor with the cooperation of the two telescopic motors.

[0091] In this way, because the two symmetrically arranged telescopic motors work together to drive the color filter to move along the axis direction of the two telescopic motors, and when the two telescopic motors stop extending, the pulling force received by the color filter is small, thereby avoiding the color filter from being damaged. Therefore, not only can the color filter be moved, but also the service life of the color filter can be improved.

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

[0093] In some embodiments of the present application, the reel structure may include: a motor and a winding rope, the motor is fixed on the side wall of the frame, one end of the winding rope is wound on the output shaft of the motor, and the second end of the winding rope is connected to the color filter.

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

[0095] When it is necessary to implement privacy protection on the left side of the display screen, the motor in the scroll structure 2 can rotate to drive the winding rope to reel in, and at the same time the motor in the scroll structure 1 can rotate in the opposite direction to drive the winding rope to extend, so that with the cooperation of the scroll structure 1 and the scroll structure 2, the color filter is driven to move to the right to reduce the left side viewing angle of the display screen body, thereby realizing privacy protection on the left side; when it is necessary to implement privacy protection on the right side of the display screen, the motors in the scroll structure 1 and the scroll structure 2 can interchange the rotation directions, thereby driving the color filter to move to the left to reduce the right side viewing angle of the display screen body, thereby realizing privacy protection on the right side.

[0096] In some embodiments of the present application, the rotational speeds of the motors in the two symmetrically arranged reel structures remain consistent.

[0097] In this way, since the color filter can be moved in a direction parallel to the connection direction of the two scroll structures through the cooperation between the two symmetrically arranged scroll structures, the circumferential offset distance and offset angle between the filter unit in the color filter and the luminous pixels in the display screen body can be adjusted, thereby achieving precise adjustment of the viewing angle of the display screen body in the connection direction, thereby achieving anti-peeping of the display screen in a specific direction.

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

[0099] In some embodiments of the present application, when the offset parameter is the smallest, the reel structure applies a certain pulling force to the compression spring through the color filter, so that the compression spring can be stretched to a certain size. If the reel structure continues to reel in the rope, the offset parameter can be gradually increased, and the extended size of the compression spring also increases accordingly. If the reel structure relaxes the rope, such as when the motor rotates in the opposite direction, the compression spring can be reset, thereby driving the color filter to move toward the compression spring. When the compression spring is reset, the offset parameter reaches the maximum again.

[0100] In this way, since the color filter can be moved in the direction of the line connecting the two by the cooperation between the compression spring and the scroll structure, the circumferential offset distance and offset angle between the filter unit in the color filter and the luminous pixels in the display screen body can be adjusted, thereby achieving precise adjustment of the viewing angle of the display screen body in the direction of the line, thereby achieving anti-peeping of the display screen in a specific direction.

[0101] In some embodiments of the present application, in Mode 1 and Mode 2, when the circumferential moving assembly includes a telescopic motor, and the number of the circumferential moving assemblies is multiple, each telescopic motor may 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, and the direction of the stress is perpendicular to the axis of the connected telescopic motor.

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

[0104] In this way, when there are multiple telescopic motors, since the multiple telescopic motors are used to drive the color filter to move in different directions, there is an angle between the output shafts of the multiple telescopic motors. Therefore, when one telescopic motor drives the color filter to move, there will be stress along the moving direction of the color filter at the connection between the color filter and other telescopic motors in the multiple telescopic motors, which may cause damage to the color filter. After an elastic connector is provided at the connection, the elastic connector can buffer the stress, thereby improving the reliability and service life of the display screen.

[0105] 2. The offset parameter is the axial offset distance

[0106] In some embodiments of the present application, when the above-mentioned offset parameter includes an axial offset distance, such as Figure 6 As shown, the above-mentioned moving mechanism may include at least two axial moving components 52 distributed along the circumference of the color filter 10. The at least two axial moving components 52 are arranged on the bottom wall of the frame 20, and at least two axial moving components 52 are connected to the color filter 10; wherein, the telescopic directions of different axial moving components 52 are the same.

[0107] It can be understood that in the above two embodiments, the at least two axially movable components can drive the color filter to move in a direction away from or close to the display screen body.

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

[0109] In some embodiments of the present application, a receiving groove for accommodating an axially movable component can be provided on the bottom wall of the frame, and the axially movable 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 a normal display mode on the other hand, that is, the circumferential offset distance is minimized.

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

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

[0112] In some embodiments of the present application, the at least two telescopic motors may include: 2 telescopic motors, 3 telescopic motors or 4 telescopic motors, which is not limited in the present application.

[0113] In some embodiments of the present application, in order to save power consumption, the at least two telescopic motors may include 2 telescopic motors.

[0114] In this way, since the color filter can be moved away from or close to the display screen body by the cooperation of at least two telescopic motors arranged on the bottom wall of the frame, the axial offset angle between the filter unit in the color filter and the luminous pixels in the display screen body can be adjusted, so that the viewing angle of the display screen body in various directions can be synchronously adjusted, so that the display screen can be protected from peeping in various directions, thereby further improving the anti-peeping effect.

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

[0116] Wherein, the at least one infrared sensor can be used to sense observation information, and the observation information can be used to indicate whether there is an observer;

[0117] The above-mentioned moving mechanism can be specifically used to move the color filter according to the observation information, and adjust the offset parameters of the filter unit in the color filter relative to the light-emitting pixels in the display screen body to adjust the viewing angle of the display screen body.

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

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

[0120] In some embodiments of the present application, the at least one infrared sensor may include: 1 infrared sensor, 2 infrared sensors, 3 infrared sensors or 4 infrared sensors.

[0121] For example, when the display screen includes one infrared sensor, the infrared sensor can be arranged close to a first area of ​​the cover plate, wherein the first area of ​​the cover plate corresponds to the front camera.

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

[0123] In some embodiments of the present application, the infrared sensor can measure the position information of the observer, 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 the present 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 may use the infrared sensor on the left side to measure whether there is an observer on the left side of the display screen, use the infrared sensor on the right side to measure whether there is an observer on the right side of the display screen, use the infrared sensor on the bottom side to measure whether there is an observer on the bottom side of the display screen, and use the infrared sensor on the top side to measure whether there is an observer on the top side of the display screen. Alternatively, the processor may perform a comprehensive calculation based on the measurement data of these sensors to determine the observer's observation angle, observation direction and observation distance. This application is not limited thereto.

[0125] In this way, since the display screen includes at least one infrared sensor distributed along the circumference of the cover plate, these sensors can be used to detect whether there is an observer, so that the moving mechanism can accurately move the color filter according to the observation information detected by the infrared sensor, thereby more accurately preventing the observer from peeping at the content displayed on the display screen, thereby improving the anti-peeping reliability of the display screen.

[0126] In some embodiments of the present application, the above-mentioned moving mechanism can be specifically used to increase the offset parameter of the filter unit in the color filter relative to the luminous pixel in the display screen body when the above-mentioned observation information indicates that there is a peeper, so as to reduce the viewing angle of the display screen body; or, the moving mechanism can be specifically used to reduce the offset parameter of the filter unit in the color filter relative to the luminous pixel in the display screen body when the observation information indicates that there is no peeper, so as to increase the viewing angle of the display screen body.

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

[0128] In some embodiments of the present application, when the offset parameter is an offset angle, the observation information may include at least one of the following: an observation angle, an observation direction, and an 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 the observation angle and the observation distance.

[0129] In some embodiments of the present application, the observation distance may 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 the present application, the observation angle may be an angle between the observer's position and the center line of the display screen.

[0131] In some embodiments of the present application, the offset parameter is an offset distance, and the above-mentioned observation information may include at least one of the following: an observation angle, an observation distance, and 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 the present application, the above embodiments are illustrated by taking the display screen body including LED, OLED or AMOLED as an example. In actual implementation, the display screen body can also be an LED display screen.

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

[0134] In the display device provided in the embodiment of the present application, since the display screen of the display device includes a moving mechanism connected to the color filter, the offset parameters of the filter unit in the color filter relative to the luminous pixels in the display screen body, such as the offset distance and the offset angle, can be adjusted by the moving mechanism, so that the viewing angle of each luminous pixel in the display screen body can be adjusted. It can be understood that the smaller the viewing angle of the display screen, the better the anti-peeping effect of the display screen. Therefore, the display screen provided in the embodiment of the present application can switch between the anti-peeping mode and the normal display mode by moving the color filter, so that not only anti-peeping can be achieved, but also the display flexibility of the display screen can be improved.

[0135] The present application also provides a display method. Figure 7 FIG. 1 shows a flow chart of a display method provided in an embodiment of the present application. The method can be executed by the display device in the above embodiment. Figure 7 As shown, the display method may include the following steps 700 and 701.

[0136] Step 700: The display device determines whether a 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 in the display screen relative to the luminous pixel in the display screen body in the display screen through the moving mechanism in the display screen to reduce the viewing angle of the display screen body.

[0138] Among them, the viewing angle of the display screen body 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 that there is an observer.

[0140] In some embodiments of the present application, the anti-peeping input may be used to trigger the display device to activate an anti-peeping function.

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

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

[0143] Exemplarily, the display device may capture an image through a front camera, so that the display device may determine observation information based on the image.

[0144] For example, the display device may determine the observation information based on information such as the number of faces, face sizes, and face positions in the image.

[0145] It can be understood that for the description of detecting observation information through the infrared sensor, refer to the relevant description in the above display screen embodiment.

[0146] It should be noted that the observation information indicating that there is an observer may include: the infrared sensor detects other users besides the user, which indicates that there is an observer, ie, other users; or the image captured by the front camera includes a face image besides the user.

[0147] In the display method provided in the embodiment of the present application, since the offset parameter of the filter unit in the color filter relative to the luminous pixel in the display screen can be increased by a moving mechanism when the first condition is met, the viewing angle of the display screen body can be reduced. That is, the anti-peeping of the display device can be achieved by reducing the viewing angle, which can improve the anti-peeping flexibility.

[0148] In some embodiments of the present application, the above-mentioned step 701 of "increasing the offset parameters of the filter unit in the color filter in the display screen relative to the luminous pixels in the display screen body in the display screen through the moving mechanism in the display screen" can be implemented by the following step A.

[0149] Step A: When the observation information indicates that there is an observer, the display device drives the color filter to move through the moving mechanism according to the observation information to increase the offset parameter of the filter unit in the color filter relative to the light-emitting pixel in the display screen 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 the present application, the offset parameter may include at least one of the following: a circumferential offset distance, an offset angle, and an axial offset distance.

[0152] In this way, when an observer is detected, the color filter can be moved by the moving mechanism according to at least one of the observer's observation distance, observation angle and observation direction. Therefore, it can be ensured that after the color filter is moved, the observer cannot see the content displayed on the display screen, thereby improving the accuracy of anti-peeping.

[0153] In some embodiments of the present application, the above-mentioned observation information may include an observation angle or an observation distance; the above-mentioned step A may be implemented through the following step A1.

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

[0155] The first distance is positively correlated with the observation information, and the first direction is any one of the following: a direction away from the display screen body, and a direction parallel to the display screen body.

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

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

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

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

[0160] In this way, 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 anti-peeping of the display screen, thereby improving anti-peeping flexibility.

[0161] It can be understood that since anti-peeping is achieved by the first base layer in the color filter blocking part of the light from the luminous pixels in the display screen body, after reducing the viewing angle of the display screen body, the brightness of the display screen at the normal viewing angle may decrease, but since the luminous pixels are not completely blocked, the resolution of the display screen remains unchanged.

[0162] In some embodiments of the present application, after the above step 701, the display method provided by the embodiment of the present application may further include the following step 702.

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

[0164] In some embodiments of the present 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 brightness of the display screen.

[0166] In this way, after reducing the viewing angle of the display screen, the brightness of the display screen can be increased to compensate for the reduction in brightness caused by the color filter blocking part of the light from the luminous pixels, thereby improving the display effect of the display screen.

[0167] In some embodiments of the present application, after the above step 701, the display method provided by the embodiment of the present application may further include the following step 703.

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

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

[0170] In some embodiments of the present application, the anti-peeping cancellation input is used to trigger the display device to turn off the anti-peeping function.

[0171] In some implementations of the present application, the display device can increase the viewing angle of the display screen body to a maximum value to achieve normal display.

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

[0173] It should be noted that when the viewing angle of the display screen is the largest, the first base layer in the color filter does not block the light of the luminous pixels, so the brightness of the display screen will not be lost.

[0174] In this way, when the display device receives the user's anti-peeping cancellation input or when the observation information indicates that there is no observer, the color filter can be driven to move by 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 body, thereby improving the display angle of the display screen and achieving normal display.

[0175] The display device in the embodiment of the present application can be an electronic device or a component in the electronic device, such as an integrated circuit or a chip. The electronic device can be a terminal or other devices other than a terminal. Exemplarily, the electronic device can be a mobile phone, a tablet computer, a laptop computer, a PDA, a vehicle-mounted electronic device, a mobile Internet device (Mobile Internet Device, MID), an augmented reality (augmented reality, AR) / virtual reality (virtual reality, VR) device, a robot, a wearable device, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a netbook or a personal digital assistant (personal digital assistant, PDA), etc. It can also be a personal computer (personal computer, PC), a television (television, TV), a teller machine or a self-service machine, etc., which is not specifically limited in the embodiment of the present application.

The electronic device may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently, which will not be described in detail here.

[0183] The processor 1510 may be used to increase, through a moving mechanism in the display screen, an offset parameter of a filter unit in a color filter in the display screen relative to a light-emitting pixel in a display screen body in the display screen when the first condition is met, so as to reduce a viewing angle of the display screen body, and 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:

[0188] When the observation information indicates that there is an observer, the color filter is driven to move by the moving mechanism according to the observation information to increase the offset parameter of the filter unit in the color filter relative to the light-emitting pixel in the display screen body;

[0196] In the electronic device provided in the embodiment of the present application, since the offset parameter of the filter unit in the color filter relative to the luminous pixels in the display screen can be increased by a moving mechanism when the first condition is met, the viewing angle of the display screen body can be reduced.
