The pixel defining layer includes a first opening and a second opening, each containing a sub-light-emitting unit. Therefore, the first and second openings correspond to two sub-pixels emitting the same color light on the display panel. The light-shielding layer includes a third opening and a fourth opening. The third opening has a first privacy segment, and the distance from the first privacy segment to the first opening is less than the distance from the fourth opening to the second opening. Therefore, the viewing angle of the portion corresponding to the first privacy segment is reduced, achieving a side privacy effect.

Therefore, the sub-pixel corresponding to the second opening can be considered a shared pixel.

Description

[0001] This application claims priority to Chinese Patent Application No. 202510935888.6, filed with the State Intellectual Property Office of China on July 7, 2025, entitled "Display Panel, Display Module, Electronic Device, Display Driving Method, Mask", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of electronic technology, and in particular to a display panel, display module, electronic device, display driving method, and photomask. Background Technology

[0003] Self-emissive display panels are widely used in electronic devices due to their high brightness, low energy consumption, long lifespan, and wide viewing angle. The wide viewing angle of self-emissive display panels also results in high screen readability at oblique viewing angles.

[0004] However, as users become increasingly aware of information privacy, privacy breaches from oblique viewing angles have become a major concern. Therefore, the privacy breach issue caused by wide viewing angles urgently needs to be addressed. While resolving privacy breaches, it's also crucial to minimize the impact on other aspects of electronic device performance. Summary of the Invention

[0005] This application provides a display panel, display module, electronic device, display driving method, and mask, for providing an electronic device with intelligent privacy protection display function.

[0006] A first aspect of this application provides a display panel, which includes a driving substrate, a pixel defining layer, a plurality of primary color light-emitting units, and a first light-shielding layer. The pixel defining layer is disposed on one side of the driving substrate and includes a plurality of opening units arranged in an array. Each opening unit includes a first opening and a second opening, with the first opening disposed on one side of the second opening along a first direction. The plurality of primary color light-emitting units are correspondingly disposed within the plurality of opening units. Each primary color light-emitting unit includes a first sub-light-emitting unit and a second sub-light-emitting unit for emitting light of the same color. The first sub-light-emitting unit is disposed within the first opening, and the second sub-light-emitting unit is disposed within the second opening. The first light-shielding layer is disposed on the side of the plurality of primary color light-emitting units away from the driving substrate. The first light-shielding layer includes a plurality of first light-emitting openings, including a third opening and a fourth opening. The projection of the first opening onto the driving substrate has a first contour, the projection of the second opening onto the driving substrate has a second contour, the projection of the third opening onto the driving substrate has a third contour, and the projection of the fourth opening onto the driving substrate has a fourth contour. The third contour includes a first privacy screen, and the maximum distance from the first privacy screen to the first contour is less than the minimum distance from the fourth contour to the second contour.

[0007] In the display panel provided in this application embodiment, the pixel defining layer includes a first opening and a second opening, and sub-light-emitting units emitting the same color light are respectively disposed in the first opening and the second opening. Therefore, the first opening and the second opening correspond to two sub-pixels emitting the same color light in the display panel. The projections of the first opening, the second opening, the third opening and the fourth opening in the first light-shielding layer correspond to a first contour, a second contour, a third contour and a fourth contour, respectively. The first contour has a first privacy segment, and the distance from the first privacy segment to the first contour is less than the distance from the fourth contour to the second contour. Therefore, the viewing angle of the part corresponding to the first privacy segment will be reduced, which can achieve the privacy effect within the coverage area of ​​the first privacy segment. Then, the sub-pixel corresponding to the first opening can be regarded as a privacy pixel. The distance from the fourth contour to the second opening is larger, which can have a better viewing angle. Then, the sub-pixel corresponding to the second opening can be regarded as a shared pixel. The display panel has pixels with two display effects, which can realize two different display effects to meet the different needs of privacy display and shared display. Furthermore, in this embodiment, the first opening and the second opening in the same unit are respectively provided with a first sub-light-emitting unit and a second sub-light-emitting unit that emit light of the same color, and there is also a first light-shielding layer to prevent crosstalk. Therefore, the gap between the first opening and the second opening in the same opening unit can be reduced, which helps to improve the pixel density of the display panel.

[0008] In one possible implementation, the third contour includes two first privacy panels located on opposite sides of the first contour along a direction intersecting the first direction. Therefore, the side containing the two first privacy panels can implement a privacy display function, and the display panel has at least two privacy display sides.

[0009] In one possible implementation, the third contour further includes a second privacy segment connected between the two first privacy segments and located away from the second contour. The minimum distance from the second privacy segment to the first contour is greater than or equal to the minimum distance from the fourth contour to the second contour. The minimum distance from the fourth contour to the second contour is the minimum distance required to achieve a privacy display function without privacy. When the minimum distance from the second privacy segment to the first contour is greater than or equal to the minimum distance from the fourth contour to the second contour, the location of the second privacy segment does not have a privacy display function, which can be applied to products that do not require four-sided privacy protection.

[0010] In one possible implementation, the third contour further includes a second privacy segment, which is connected between the two first privacy segments and is located away from the second contour; the minimum distance from the second privacy segment to the first contour is less than the minimum distance from the fourth contour to the second contour. Therefore, a privacy display function can also be implemented at the location of the second privacy segment, and the display panel has a privacy display function on at least three sides.

[0011] In one possible implementation, the opening unit further includes a fifth opening, which is located on the side of the first opening away from the second opening; the projection of the fifth opening onto the driving substrate has a fifth contour; the primary color light-emitting unit further includes a third sub-light-emitting unit that emits light of the same color as the first sub-light-emitting unit, and the third sub-light-emitting unit is located within the fifth opening; the light-emitting opening further includes a sixth opening, which is located on the side of the third opening away from the fourth opening; the projection of the sixth opening onto the driving substrate has a sixth contour; the maximum distance from the first privacy segment to the first contour is less than the minimum distance from the sixth contour to the fifth contour; the third contour includes two first privacy segments, which are located on opposite sides of the first contour along a direction intersecting the first direction. Thus, the display panel can achieve a privacy display function on the side where the first privacy segment is located. Furthermore, the opening unit includes three openings, each corresponding to a sub-pixel, which can increase the pixel density of the display panel.

[0012] In one possible implementation, the display panel includes a camera area, with the side of the display panel closest to the camera area designated as the top side, and the first direction being from the bottom side to the top side. Therefore, the two first privacy protection segments are located on the left and right sides of the display panel, enabling privacy protection on both sides.

[0013] In one possible implementation, the maximum distance from the third contour to the first contour is less than the minimum distance from the fourth contour to the second contour. Therefore, the entire third contour provides privacy protection, enabling the display panel to be privacy-protected from all four sides.

[0014] In one possible implementation, the display panel further includes a second light-shielding layer. This second light-shielding layer is disposed on the side of the plurality of primary color light-emitting units away from the driving substrate and has a gap with the first light-shielding layer. The second light-shielding layer includes a plurality of second light-emitting openings, including a seventh opening and an eighth opening. The projection of the seventh opening onto the driving substrate overlaps with the projection of the third opening onto the driving substrate. Of the fourth and eighth openings, the projection of the one farther from the driving substrate onto the driving substrate covers the projection of the one closer to the driving substrate onto the driving substrate. By providing two spaced-apart first and second light-shielding layers in the display panel, the light-shielding layer closer to the driving substrate can block large-angle light, while the light-shielding layer farther from the driving substrate can block small-angle light, thus limiting the light emission angle and improving the privacy protection effect.

[0015] In one possible implementation, the distance from each position of the third contour to the first contour is equal, which simplifies the design.

[0016] In one possible implementation, the distances from each position of the first privacy segment to the first contour are not completely equal, and the first privacy segment includes portions that are concave or convex relative to the first contour. By making the distances from each position of the first privacy segment to the first contour not completely equal, the privacy viewing angle can be reasonably adjusted according to the privacy requirements at different angles, thereby improving the display effect while ensuring the privacy effect.

[0017] In one possible implementation, the display panel includes a touch stack, with a first light-shielding layer disposed on the side of the touch stack away from the driving substrate. Forming the first light-shielding layer after the touch stack avoids altering the structure of the touch stack, resulting in minimal structural changes.

[0018] In one possible implementation, the second light-shielding layer is disposed on the side of the first light-shielding layer away from the touch stack. Forming the second light-shielding layer after the touch stack avoids altering the structure of the touch stack, resulting in minimal structural changes.

[0019] In one possible implementation, the display panel further includes a touch connection layer disposed between the touch stack and multiple primary color light-emitting units; a second light-shielding layer is disposed on the side of the touch stack facing the driving substrate, and the touch connection layer covers the second light-shielding layer. This eliminates the need for a separate transparent optical adhesive layer to cover the second light-shielding layer, reducing the number of film layers. Furthermore, since the touch stack separates the second light-shielding layer from the first light-shielding layer, there is no need for a separate film layer to adjust the gap between the two layers, further reducing the thickness of the display panel and improving its reliability.

[0020] In one possible implementation, the touch stack includes an electrode layer, which is reused as a second light-shielding layer. By reusing the electrode layer as a second light-shielding layer in the touch stack, a separate second light-shielding layer can be eliminated, reducing the number of film layers and thus the thickness of the display panel.

[0021] In one possible implementation, the display panel further includes a third light-shielding layer; the second light-shielding layer is disposed on the side of the first light-shielding layer away from the driving substrate, and the third light-shielding layer is disposed between the first and second light-shielding layers; the third light-shielding layer includes a plurality of third light-emitting openings, including a tenth opening and an eleventh opening; the projection of the tenth opening onto the driving substrate covers the projection of the third opening onto the driving substrate; the projection of the eleventh opening onto the driving substrate falls within the projection of the eighth opening onto the driving substrate and covers the projection of the fourth opening onto the driving substrate. The third light-shielding layer is disposed between the first and second light-shielding layers by opening a tenth opening and an eleventh opening with different sizes than the openings in the second and second light-shielding layers. This staggered structure allows the light emitted by the privacy pixel to be partially blocked by the second light-shielding layer and partially blocked by the third light-shielding layer. For example, the small-angle light emitted by the privacy pixel is blocked by the second light-shielding layer, and the large-angle light emitted is blocked by the third light-shielding layer. Therefore, the portion of the second light-shielding layer originally used to block the large-angle light emitted can be removed, thereby reducing the size of the light-shielding strip in the second light-shielding layer. After the size of the light-shielding strip in the second light-shielding layer is reduced, the light-shielding effect of the second light-shielding layer on the shared pixel is reduced, which can increase the light-emitting angle of the shared pixel and improve the brightness decay of the shared state at a large viewing angle.

[0022] In one possible implementation, the display panel further includes a touch stack, which includes an electrode layer that is reused as a third light-shielding layer. Reusing the electrode layer in the touch stack as a third light-shielding layer reduces the number of film layers in the display panel, thereby reducing the panel's thickness and improving its reliability.

[0023] In one possible implementation, the third and fourth openings are connected, as are the seventh and eighth openings. Connecting the openings reduces the proportion of the occluded area and increases the aperture ratio.

[0024] In one possible implementation, along a direction perpendicular to the first opening to the second opening, the second light-emitting opening has a minimum size in the portion located between the first and second openings, a first maximum size in the portion located outside the first opening, and a second maximum size in the portion located outside the second opening; the minimum size is smaller than the first and second maximum sizes. By reducing the size of the second light-emitting opening in the portion located between the first and second openings, the brightness attenuation and color transition of the privacy pixel's downward viewing angle and the shared pixel's upward viewing angle can be made more uniform, improving the display effect.

[0025] In one possible implementation, the display panel further includes a color filter layer disposed within multiple first light-emitting openings; the first, second, third, and fourth contours are curved edges. The color filter layer has high transmittance, and using it can improve the transmittance of the display panel. However, since the color filter layer cannot change the polarization state of the light, the diffraction characteristics of each sub-light-emitting unit are crucial. When each sub-light-emitting unit is curved, the diffraction intensity is uniform at all positions along the curved edge, resulting in a more uniform display effect.

[0026] In one possible implementation, the display panel further includes a color filter layer disposed within a plurality of second light-emitting openings. The color filter layer includes a first sub-primary color filter layer and a second sub-primary color filter layer. The first and second sub-primary color filter layers are correspondingly disposed within two adjacent seventh and eighth openings located at different second light-emitting openings. The dimension of the second sub-primary color filter layer near the edge of the first sub-primary color filter layer to the edge of the fourth opening near the edge of the first sub-primary color filter layer is greater than or equal to 0.5µm. Since the second sub-primary color filter layer extends an additional 0.5µm towards the first sub-primary color filter layer, it can block light emitted by the light-emitting unit located below the first sub-primary color filter layer, thus preventing crosstalk between privacy pixels of different colors and shared pixels. Furthermore, the second sub-primary color filter layer can transmit light emitted by the light-emitting unit in the shared pixel below it. Therefore, extending the second primary color filter layer by 0.5µm can increase the light emission angle of the shared pixels, improve the brightness of the shared pixels, and make the proportion of different colors more balanced, thereby improving the brightness decay and viewing angle color deviation of the shared state at a large viewing angle.

[0027] In one possible implementation, the display panel further includes a color filter layer disposed on the side of the first light-shielding layer away from the driving substrate. The color filter layer includes a first portion, a second portion, and a third portion. The first and second portions are correspondingly disposed on the light-emitting sides of two adjacent first and second sub-light-emitting units that emit different colors of light. The third portion is disposed between the first and second portions. The third portion and the first portion are used to transmit light of different colors. Because the third portion and the first portion are used to transmit light of different colors, the light emitted by the first sub-light-emitting unit emitting the first color of light cannot pass through the third portion. This can block the oblique light emission from the privacy pixel where the first sub-light-emitting unit is located to the dissimilar color-sharing pixel where the second sub-light-emitting unit is located, thus preventing crosstalk. By using a color filter layer to achieve crosstalk prevention, a separate light-shielding layer is not required, which simplifies the process and reduces the number of film layers in the display panel.

[0028] In one possible implementation, the third part and the second part are used to transmit light of different colors. Thus, the first, second, and third parts are used to transmit light of different colors. This prevents the light emitted by the second sub-light-emitting unit from escaping through the third part, blocking the oblique light emission from the shared pixel containing the second sub-light-emitting unit to the privacy pixel containing the first sub-light-emitting unit, thereby improving the anti-crosstalk effect.

[0029] In one possible implementation, the dimension from the edge of the third part near the edge of the second part to the edge of the fourth opening near the edge of the first part is greater than or equal to 0.5 μm. This is equivalent to increasing the size of the second part, thereby increasing the light emission angle of the second sub-emitting unit, which can improve the brightness of the shared pixel, make the proportion of different colors more balanced, and thus improve the brightness decay and viewing angle deviation of the shared state over a large viewing angle.

[0030] In one possible implementation, the color filter layer includes a blue light filter unit, a red light filter unit, and a green light filter unit, with the blue light filter unit having the smallest thickness. By thinning the blue light filter unit, the transmittance of blue light can be increased to ensure the brightness balance of the three primary colors and improve the color lifetime.

[0031] In one possible implementation, the display panel includes a touch stack, which comprises a first electrode layer and a second electrode layer. The first electrode layer is reused as a first light-shielding layer, and the second electrode layer is reused as a second light-shielding layer. The first electrode layer includes a plurality of first touch electrodes and a plurality of first redundant electrodes, which together form a plurality of first light-emitting openings. The second electrode layer includes a plurality of second touch electrodes and a plurality of second redundant electrodes, which together form a plurality of second light-emitting openings. Since the first electrode layer is reused as a first light-shielding layer and the second electrode layer is reused as a second light-shielding layer, a separate light-shielding layer is not required, further reducing the thickness of the display panel.

[0032] In one possible implementation, the gap between the seventh and eighth openings is greater than 3µm. This effectively increases the light-shielding area of ​​the electrode layer, reducing light leakage interference between sub-pixels emitting the same type of light.

[0033] In one possible implementation, the display panel further includes a polarizer positioned close to the light-emitting surface of the display panel; the first, second, third, and fourth contours are polygonal. Using a polarizer for light filtering is simple in structure and low in cost. Furthermore, when using a polarizer for light filtering, the uneven diffraction at the sharp corners of the polygons has little impact on the display effect. Therefore, setting the contours to polygons allows for an increase in aperture ratio while maintaining display quality.

[0034] In one possible implementation, multiple primary color light-emitting units include a first primary color light-emitting unit and a second primary color light-emitting unit; multiple opening units include a first opening unit and a second opening unit; the first primary color light-emitting unit is disposed within the first opening unit, and the second primary color light-emitting unit is disposed within the second opening unit; in the first opening unit, the maximum distance from the first privacy screen segment of the first opening to the first contour is a first distance; in the second opening unit, the maximum distance from the first privacy screen segment of the first opening to the first contour is a second distance; the first distance is less than the second distance. For example, the first primary color light-emitting unit is a blue light-emitting unit, and the second primary color light-emitting unit is a red light-emitting unit or a green light-emitting unit. That is, the first light-shielding layer has different degrees of obstruction for each primary color light-emitting unit, and the color mixing ratio of each primary color light can be adjusted by combining the characteristics such as the emitted color and the aperture ratio to improve color deviation. For example, the first opening where the blue light-emitting unit is located has a larger degree of obstruction, which can reduce the amount of blue light emitted from the wide viewing angle, effectively blocking blue light from overflowing to the red or green light unit, preventing the disruption of the red, green, and blue color mixing ratio, and improving color deviation.

[0035] In some embodiments of this application, the area of ​​the aperture unit containing the blue light-emitting unit is larger than the area of ​​the aperture unit containing the non-blue light-emitting unit. By increasing the area of ​​the aperture unit containing the blue light-emitting unit, the aperture ratio of the blue light-emitting unit can be increased, thereby increasing the amount of blue light transmitted, ensuring the brightness balance of the three primary colors, and improving the color lifetime.

[0036] In one possible implementation, the maximum distance from the first privacy segment to the first contour is less than 2µm. This avoids the privacy pixel having too large an aperture ratio, ensuring the privacy protection effect.

[0037] In one possible implementation, the distance from the fourth contour to the second contour is greater than or equal to 2µm. This increases the aperture ratio of the shared pixels.

[0038] In one possible implementation, the distance between the first and second openings within the same opening unit is greater than or equal to 5µm. Having an opening spacing of greater than or equal to 5µm between corresponding pixels of the same color can reduce lateral crosstalk between sub-units emitting the same color light within the same unit, while simultaneously ensuring the pixel density of the display panel.

[0039] In one possible implementation, in two adjacent opening units along a direction oblique to the first direction, the distance from the second opening of one opening unit to the first opening of the other opening unit is greater than or equal to 5µm. Having a spacing of greater than or equal to 5µm between the openings corresponding to different colored pixels can weaken lateral crosstalk between sub-units emitting different colors of light, while ensuring the pixel density of the display panel.

[0040] In one possible implementation, the optical density of the pixel boundary layer is greater than 1. Each primary color emissive unit includes a first sub-emissive unit and a second sub-emissive unit, and the design for each primary color emissive unit is asymmetrical. This requires minimal diffraction interference between adjacent sub-emissive units to ensure display quality. By designing the optical density of the pixel boundary layer to be greater than 1, the light absorption rate of the pixel boundary layer can be increased, and the lateral diffraction between sub-emissive units can be reduced.

[0041] In one possible implementation, the inner edge of the pixel defining layer near the opening unit is a bevel. For example, the angle between the inner edge and the thickness direction of the pixel defining layer is greater than 15°. When light strikes the inner edge at a larger incident angle, the reflected light is more easily absorbed outside the guide panel or by the pixel defining layer itself, weakening the lateral light diffracted between sub-pixels and reducing diffraction diffusion to adjacent sub-pixels. In some embodiments of this application, the inner edge of the first light-shielding layer near the first light-emitting opening is a bevel. For example, the angle between the inner edge and the thickness direction of the first light-shielding layer is greater than 15°. When light strikes the inner edge at a larger incident angle, the reflected light is more easily absorbed outside the guide panel or by the first light-shielding layer itself, reducing diffraction diffusion to adjacent sub-pixels.

[0042] In one possible implementation, the first sub-light-emitting unit includes multiple light-emitting devices connected in series, and the second sub-light-emitting unit also includes multiple light-emitting devices connected in series. At the same light-emitting power consumption, the stacked structure can achieve higher brightness. At the same brightness, the stacked structure can effectively reduce light-emitting power consumption. This helps to improve the lifespan of both the first and second sub-light-emitting units. When an electronic device adopts a stacked structure + color filter layer structure, the brightness and power consumption of the display panel are also relatively superior.

[0043] In one possible implementation, the driving substrate includes a substrate and a first light-emitting control module and a second light-emitting control module; the first and second light-emitting control modules are used to receive different light-emitting control signals; in the same primary color light-emitting unit, the first sub-light-emitting unit is coupled to the first light-emitting control module, and the second sub-light-emitting unit is coupled to the second light-emitting control module. By controlling the first sub-light-emitting unit corresponding to the privacy pixel and the second sub-light-emitting unit corresponding to the shared pixel through different light-emitting control modules, the display panel can switch between privacy mode and sharing mode.

[0044] A second aspect of the embodiments of this application provides a display module, the display module including a display driver integrated circuit and a display panel; the display driver integrated circuit is coupled to the display panel; the display panel includes the display panel as described in any of the first aspects.

[0045] A third aspect of the embodiments of this application provides an electronic device, which includes a drive controller and a display module, wherein the drive controller is coupled to the display module; the display module includes the display module of the second aspect.

[0046] A fourth aspect of this application provides an electronic device, comprising: a display panel, one or more processors, and one or more memories; the one or more memories are coupled to the one or more processors, and the one or more memories are used to store computer program code, the computer program code including computer instructions, wherein when the one or more processors execute the computer instructions, the electronic device performs: in a first display mode, the display panel displays an image from a first viewing angle; upon determining that preset conditions are met, the device switches from the first display mode to a second display mode, the display panel displays an image from a second viewing angle, the first viewing angle being greater than the second viewing angle; wherein the preset conditions include at least one of the following: the number of faces is greater than 1 or the number of eyes is greater than 1, there is a non-pre-stored user, a face or eye with an angle greater than a preset angle with the electronic device, the user confirms entering the second display mode, the mode switching function is enabled, and the anti-peeping application is started.

[0047] The electronic device provided in this application embodiment has a first display mode and a second display mode. By setting preset conditions, the electronic device intelligently switches between the first and second display modes based on whether these conditions are met. For example, if the first display mode is a sharing mode and the second display mode is a privacy mode, the electronic device can intelligently switch between the privacy mode and the sharing mode to improve user experience. Furthermore, if multiple preset conditions are included, the mode is switched only when all preset conditions are met, which can improve the accuracy of the judgment conclusion.

[0048] In one possible implementation, one or more processors are further configured to, when executing computer instructions, cause the electronic device to: display a first user interface on a display panel, the first user interface including a target control for activating the privacy screen function. By displaying the first user interface, the user can easily and directly activate the privacy screen function.

[0049] In one possible implementation, one or more processors are further configured to, when executing computer instructions, cause the electronic device to: display a second user interface, the second user interface including a target prompt box for prompting the user whether to enter a second display mode. By displaying the second user interface, it is easier for the user to confirm whether to switch to the second display mode, thus improving the accuracy of mode switching.

[0050] A fifth aspect of this application provides a display driving method executed in an electronic device. The display driving method includes: the electronic device displaying an image from a first perspective in a first display mode; determining that preset conditions are met, the electronic device switches from the first display mode to a second display mode, displaying the image from a second perspective, where the first perspective is larger than the second perspective; wherein the preset conditions include at least one of the following: the number of faces is greater than 1 or the number of eyes is greater than 1; there is a non-pre-stored user; there is a face or eye with an angle greater than a preset angle with the electronic device; or the user confirms entering the second display mode. The display driving method provided in this application intelligently switches between the first and second display modes by determining whether preset conditions are met. For example, if the first display mode is a sharing mode and the second display mode is a privacy mode, the electronic device can intelligently switch between the privacy mode and the sharing mode to improve the user experience. Furthermore, when multiple preset conditions are present, switching modes only occurs when all preset conditions are met, which improves the accuracy of the determination.

[0051] In one possible implementation, the display driver method further includes: receiving a first operation from user input; the first operation is used to enable the privacy display function. Determining whether to switch display modes only after receiving the first operation avoids the need for size-based mode switching, thus reducing power consumption.

[0052] In one possible implementation, the display driver method further includes: receiving a first operation from user input; the first operation is used to initiate applications that are pre-marked as requiring privacy protection. Determining whether to switch display modes only after receiving the first operation avoids the need for size-based mode switching, thus reducing power consumption.

[0053] A sixth aspect of the embodiments of this application provides a photomask, the photomask including a body, multiple rows of first openings, and multiple rows of second openings; the multiple rows of first openings and multiple rows of second openings are alternately arranged along a first direction; the distance from the first opening to the second opening is greater than the distance from the second opening to the first opening along the first direction; the distance between the first opening and the second opening is greater than or equal to 5 μm along the first direction; the first direction intersects with the row direction.

[0054] In one possible implementation, the outlines of the first and second openings are curved.

[0055] A seventh aspect of this application provides an electronic device, which includes a drive controller and a display module. The display panel in the display module includes a first primary color light-emitting unit and a second primary color light-emitting unit, the second primary color light-emitting unit being located away from the center of the display panel relative to the first primary color light-emitting unit. The first primary color light-emitting unit includes a first sub-light-emitting unit and a second sub-light-emitting unit for emitting light of the same color, and the second primary color light-emitting unit includes a third sub-light-emitting unit and a fourth sub-light-emitting unit for emitting light of the same color. The drive controller receives first image data; the first image data includes first grayscale data corresponding to the first primary color light-emitting unit and second grayscale data corresponding to the second primary color light-emitting unit; both the first grayscale data and the second grayscale data represent the first grayscale. In a third display mode, the drive controller outputs a first image signal based on the first image data, and the display module drives the first sub-light-emitting unit and the third sub-light-emitting unit to emit light in response to the first image signal; at a normal viewing angle, the luminance of the first sub-light-emitting unit is a first luminance, and the luminance of the third sub-light-emitting unit is a second luminance. In the fourth display mode, the drive controller outputs a second image signal based on the first image data, and the display module responds to the second image signal by driving the second and fourth sub-light-emitting units to emit light. At a normal viewing angle, the brightness of the second sub-light-emitting unit is the third brightness, and the brightness of the fourth sub-light-emitting unit is the fourth brightness. The second brightness is greater than the first brightness, and the fourth brightness is equal to the third brightness.

[0056] For electronic devices with both sharing and privacy display modes, in privacy mode, the brightness of the display panel decreases rapidly as the viewing angle increases. This leads to a greater difference in brightness between the left and right eyes within the human eye's field of vision, increasing the strain on the binocular muscles. Furthermore, the brain struggles to fuse the viewed image after it passes through the visual nerves, resulting in dizziness and tension. Additionally, in privacy mode, the user's viewing angle at the edges of the display panel is somewhat limited, causing the edge brightness to appear lower. In sharing mode, this lower edge brightness is less noticeable or nonexistent. This results in a sudden change in edge brightness when switching between privacy and sharing modes. This application's embodiment addresses this issue by specifically increasing the brightness of the primary color light-emitting units far from the center of the display panel in the third display mode (privacy mode), thereby reducing the problem of perceived lower edge brightness. This reduces the difference in brightness between the two eyes, improves dizziness, and optimizes the brightness difference issue during mode switching.

[0057] In one possible implementation, the display panel further includes a third primary color light-emitting unit, which is located further away from the center of the display panel than the second primary color light-emitting unit. The third primary color light-emitting unit includes a fifth sub-light-emitting unit and a sixth sub-light-emitting unit for emitting light of the same color. The first image data also includes third grayscale data corresponding to the third primary color light-emitting unit; the third grayscale data represents the first grayscale. The display module is also used to drive the fifth sub-light-emitting unit to emit light in response to the first image signal; at a normal viewing angle, the luminance of the fifth sub-light-emitting unit is the fifth luminance. The ratio of the fifth luminance to the first luminance is greater than the ratio of the second luminance to the first luminance. Since the visual brightness decreases the further away from the center of the display panel, the greater the increase in brightness of the sub-light-emitting unit, which can further improve the uniformity of brightness between the left and right eyes. Sub-light-emitting units equidistant from the center of the display panel can, for example, have the same increase in brightness.

[0058] In one possible implementation, the first image signal output by the drive controller includes a first grayscale signal corresponding to the first sub-light-emitting unit and a second grayscale signal corresponding to the third sub-light-emitting unit; the first grayscale signal represents the second grayscale, the second grayscale signal represents the third grayscale, the third grayscale is greater than the second grayscale, and the second grayscale is greater than or equal to the first grayscale. By boosting the grayscale by the drive controller, the brightness of the sub-light-emitting units far from the center of the display panel can be increased.

[0059] In one possible implementation, the display module includes a display driver integrated circuit and a display panel. The display driver integrated circuit, in response to a first image signal, sends a first data voltage to a first sub-light-emitting unit and a second data voltage to a third sub-light-emitting unit; the first data voltage and the second data voltage are different. The display panel, in response to the first and second data voltages, drives the first and third sub-light-emitting units to emit light. By adjusting the data voltages through the display driver integrated circuit, the brightness of the sub-light-emitting units located away from the center of the display panel can be increased.

[0060] An eighth aspect of this application provides a driving method for an electronic device. The electronic device includes a driving controller and a display module. The display panel in the display module includes a first primary color light-emitting unit and a second primary color light-emitting unit, with the second primary color light-emitting unit located away from the center of the display panel relative to the first primary color light-emitting unit. The first primary color light-emitting unit includes a first sub-light-emitting unit and a second sub-light-emitting unit for emitting light of the same color, and the second primary color light-emitting unit includes a third sub-light-emitting unit and a fourth sub-light-emitting unit for emitting light of the same color. The driving controller receives first image data; the first image data includes first grayscale data corresponding to the first primary color light-emitting unit and second grayscale data corresponding to the second primary color light-emitting unit; both the first grayscale data and the second grayscale data represent the first grayscale. In a third display mode, the driving controller outputs a first image signal according to the first image data, and the display module responds to the first image signal by driving the first sub-light-emitting unit and the third sub-light-emitting unit to emit light; at a normal viewing angle, the luminance of the first sub-light-emitting unit is a first luminance, and the luminance of the third sub-light-emitting unit is a second luminance. In the fourth display mode, the drive controller outputs a second image signal based on the first image data. The display module responds to the second image signal, driving the second and fourth sub-light-emitting units to emit light. At a normal viewing angle, the brightness of the second sub-light-emitting unit is the third brightness, and the brightness of the fourth sub-light-emitting unit is the fourth brightness. The second brightness is greater than the first brightness, and the fourth brightness is equal to the third brightness. The beneficial effects of the driving method for the electronic device provided in the eighth aspect of this application are the same as those of the electronic device provided in the seventh aspect, and will not be repeated here.

[0061] In one possible implementation, the display panel further includes a third primary color light-emitting unit, which is located away from the center of the display panel relative to the second primary color light-emitting unit. The third primary color light-emitting unit includes a fifth sub-light-emitting unit and a sixth sub-light-emitting unit for emitting light of the same color. The first image data also includes third grayscale data corresponding to the third primary color light-emitting unit; the third grayscale data characterizes the first grayscale. The display module also responds to the first image signal by driving the fifth sub-light-emitting unit to emit light; at a normal viewing angle, the luminance of the fifth sub-light-emitting unit is the fifth luminance. The ratio of the fifth luminance to the first luminance is greater than the ratio of the second luminance to the first luminance.

[0062] In one possible implementation, the first image signal output by the drive controller includes a first grayscale signal corresponding to the first sub-light-emitting unit and a second grayscale signal corresponding to the third sub-light-emitting unit; the first grayscale signal represents the second grayscale, the second grayscale signal represents the third grayscale, the third grayscale is greater than the second grayscale, and the second grayscale is greater than or equal to the first grayscale.

[0063] In one possible implementation, the display module includes a display driver integrated circuit and a display panel; the display driver integrated circuit, in response to a first image signal, sends a first data voltage to a first sub-light-emitting unit and a second data voltage to a third sub-light-emitting unit; the first data voltage and the second data voltage are different; the display panel, in response to the first data voltage and the second data voltage, drives the first sub-light-emitting unit and the third sub-light-emitting unit to emit light.

[0071] For ease of explanation, this application uses a mobile phone as an example of an electronic device for illustrative purposes.

[0072] Figures 1A-1C The diagram shows the structure of some electronic devices provided in the embodiments of this application.

[0073] In some embodiments of this application, such as Figure 1A As shown, electronic device 1 is a candybar phone. Electronic device 1 mainly includes a display module 10, a mid-frame 20, and a back cover 30 (or back shell, battery cover, etc.). The display module 10 is mounted on the mid-frame 20, which supports the display module 10. The back cover is mounted on the mid-frame 20, forming a receiving space with the side of the mid-frame 20 away from the display module 10.

[0074] In some embodiments of this application, the electronic device 1 further includes a drive controller, which serves as the core of the electronic device 1 and is used for overall system processing and control. The drive controller is coupled to the display module 10 and receives image signals and control signals (e.g., provided by a central processing unit (CPU)). The drive controller outputs image data matching the interface specifications of the display module 10 based on the image signals. The drive controller may include, for example, a system-on-chip (SOC). The drive controller can be coupled to the display module 10 via a mobile industry processor interface (MIPI). Alternatively, the drive controller can also be coupled to the display module 10 via other high-speed serial / deserial (SerDes) interfaces.

[0075] Other electronic components, such as a printed circuit board (PCB), battery, receiver, speaker, and camera, can also be disposed on the side of the middle frame 20 away from the display module 10. The PCB can integrate electronic components such as the electronic device's storage unit, antenna module, and power management unit (PMU), while the battery can power the display module 10, PCB, receiver, speaker, and camera. Of course, this embodiment does not limit the electronic components disposed on the frame 20.

[0076] In other embodiments, such as Figure 1B As shown, electronic device 1 is a two-fold device. Electronic device 1 includes a display module 10, a middle frame 20, and a back cover ( Figure 1B (Not shown in the image).

[0077] The middle frame 20 includes a first frame 201, a second frame 202, and a first pivot mechanism 203. The first frame 201 and the second frame 202 are disposed on both sides of the first pivot mechanism 203, and the first pivot mechanism 203 is connected to the first frame 201 and the second frame 202 respectively. The first frame 201 and the second frame 202 can be used to support the flexible display module 10, so that the flexible display module 10 remains as flat as possible during use and protects the non-display surface of the flexible display module 10. For example, a part of the display module 10 is fixed to the first frame 201 by an adhesive layer, and a part is fixed to the second frame 202 by an adhesive layer. The adhesive layer can be a thin film layer formed after applying glue, and the specific form of the adhesive layer is not limited in the embodiments of this application.

[0078] The display module 10 is a foldable display module. In its flattened state, the display module 10 has a first non-bending area 101, a second non-bending area 102, and a first bendable area 103 connecting the first non-bending area 101 and the second non-bending area 102 in the horizontal direction. For example, the display module 10 may include a first non-bending area 101 corresponding to the first frame 201, a second non-bending area 102 corresponding to the second frame 202, and a first bendable area 103 corresponding to the first pivot mechanism 203. The first non-bending area 101 can be connected to the first frame 201, and the second non-bending area 102 can be connected to the second frame 202.

[0079] Under the action of the first pivot mechanism 203, the first frame 201 and the second frame 202 can move closer to each other or further away from each other. Correspondingly, the first non-bending area 101 and the second non-bending area 102 of the display module 10 can move closer to each other or further away from each other, so that the display module 10 can be folded or unfolded.

[0080] In some other embodiments, such as Figure 1C As shown, electronic device 1 is a multi-folding device. Figure 1C The following diagram illustrates an electronic device 1 as a multi-folding device. Electronic device 1 includes a display module 10 and a middle frame 20.

[0081] The middle frame 20 includes a first frame 201, a second frame 202, a first rotating mechanism 203, a third frame 204, and a second rotating mechanism 205. The first frame 201 and the second frame 202 are disposed on both sides of the first rotating mechanism 203, and the first rotating mechanism 203 is connected to the first frame 201 and the second frame 202 respectively. The second frame 202 and the third frame 204 are disposed on both sides of the second rotating mechanism 205, and the second rotating mechanism 205 is connected to the second frame 202 and the third frame 204 respectively.

[0082] In its flattened state, the horizontally oriented display module 10 has a first non-bending area 101, a second non-bending area 102, a first bendable area 103 connecting the first non-bending area 101 and the second non-bending area 102, a third non-bending area 104, and a second bendable area 105 connecting the third non-bending area 104 and the second non-bending area 102. For example, the display module 10 may include a first non-bending area 101 corresponding to the first frame 201, a second non-bending area 102 corresponding to the second frame 202, a first bendable area 103 corresponding to the first pivot mechanism 203, a third non-bending area 104 corresponding to the third frame 204, and a second bendable area 105 corresponding to the second pivot mechanism 205.

[0083] When the electronic device 1 is a folding device, the folding direction of the electronic device 1 is not limited in this embodiment of the application. The electronic device 1 can be folded inward, outward, inward and outward, horizontal, and other ways.

[0084] In some embodiments of this application, the display module 10 includes, for example, a display panel and a display driver integrated circuit. The display driver integrated circuit serves as the control core of the display panel, used to drive the display panel to work and receive data from the driver controller.

[0085] The display driver integrated circuit, for example, is coupled to the driver controller, receives signals output by the driver controller, and provides the scanning signals and data signals required for the display panel to emit light. The signals sent by the display driver integrated circuit will be explained in detail below in conjunction with the structure of the pixel circuit.

[0086] For example, the display driver integrated circuit receives data control signals and image data from the driver controller. The display driver integrated circuit converts the image data into data signals and outputs these data signals to multiple data signal lines. The data signals are analog voltages corresponding to the grayscale values ​​of the image data. The display driver integrated circuit is also used to output scan control signals such as clock signals, gate activation signals (STV), and reset signals required for display to the display panel. The display driver integrated circuit includes, for example, a display driver integrated circuit (DDIC).

[0087] The display panel, as a data presentation unit, is used to display and control data sent by the drive controller. Examples of display panels include organic light-emitting diode (OLED) display panels, active-matrix organic light-emitting diode (AMOLED) display panels, mini organic light-emitting diode (Mini-OLED) display panels, micro light-emitting diode (Micro-LED) display panels, micro organic light-emitting diode (Micro-OLED) display panels, quantum dot light-emitting diode (QLED) display panels, and other self-emissive display panels.

[0088] For any of the above-described display panels 100, the display panel 100 includes an active display area (AA) and a non-display area surrounding the active display area. The active display area is used to display images and includes multiple sub-pixels (SPs). Each sub-pixel contains a pixel circuit that receives data signals provided by a display driver integrated circuit. The non-display area includes a row driving circuit that receives scan control signals provided by the display driver integrated circuit.

[0089] Because self-emissive display panels offer a wide viewing angle and high readability at angled viewing angles, consumers are increasingly using privacy screen protectors to achieve this effect and protect their privacy, especially as users become more aware of information privacy.

[0090] However, privacy screen protectors are generally optical venetian blinds, which reduces screen brightness after application. When placed on the light-emitting side of the display panel, they reduce light emission efficiency, thus hindering device lifespan. Furthermore, the overlap between the privacy screen protector and the light-emitting pixels produces significant diffraction, degrading screen clarity. Moreover, with a privacy screen protector applied, electronic device 1 remains in a privacy mode, unable to flexibly switch between privacy and shared modes depending on the usage scenario.

[0091] Figure 2 This is a schematic diagram of the layout of a display panel provided in an embodiment of this application.

[0092] To address the problems caused by applying privacy films, in some embodiments of this application, such as... Figure 2 As shown, the display panel includes a first red sub-pixel R1, a second red sub-pixel R2, a first green sub-pixel G1, a second green sub-pixel G2, a first blue sub-pixel B1, and a second blue sub-pixel B2. The first red sub-pixel R1, first green sub-pixel G1, and first blue sub-pixel B1 serve as a privacy pixel P1, displayed in privacy mode. The second red sub-pixel R2, second green sub-pixel G2, and second blue sub-pixel B2 serve as a shared pixel P2, displayed in shared mode. A pixel segmentation scheme is adopted, with the privacy pixel P1 and shared pixel P2 set separately. The luminous pixels are switched, and a light-blocking layer or a prism-based light-gathering structure is used to achieve the privacy effect. In normal mode, all pixels or the shared pixel is enabled; in privacy mode, only the privacy pixel is enabled. Although this achieves a certain degree of privacy, the aperture ratio is small in privacy mode. To maintain the same brightness, the current density needs to be increased, posing a serious risk of flask burning. Furthermore, the pixel density (pixels per inch, PPI) is low.

[0093] Figure 3A This is a schematic diagram of another display panel layout provided in an embodiment of this application.

[0094] This application provides a display panel 100, which includes a plurality of primary color display units arranged in an array. Each primary color display unit includes a plurality of sub-pixels that emit light of the same color, and the plurality of sub-pixels are arranged along a first direction.

[0095] Figure 3A The illustration uses an example where each primary color display unit includes two sub-pixels emitting the same color light. For instance, the primary color display units in the display panel 100 include a red primary color display unit R, a green primary color display unit G, and a blue primary color display unit B. The red primary color display unit R includes a first red sub-pixel R1 and a second red sub-pixel R2, with the first red sub-pixel R1 positioned along a first direction X on one side of the second red sub-pixel R2. The green primary color emitting unit G includes a first green sub-pixel G1 and a second green sub-pixel G2, with the first green sub-pixel G1 positioned along a first direction X on one side of the second green sub-pixel G2. The blue primary color emitting unit B includes a first blue sub-pixel B1 and a second blue sub-pixel B2, with the first blue sub-pixel B1 positioned along a first direction X on one side of the second blue sub-pixel B2.

[0096] The first red sub-pixel R1, the first green sub-pixel G1, and the first blue sub-pixel B1 form a privacy pixel P1, and the second red sub-pixel R2, the second green sub-pixel G2, and the second blue sub-pixel B2 form a shared pixel P2. The privacy pixel P1 and the shared pixel P2 are arranged alternately.

[0097] Figure 3A The arrangement of the red light primary color emitting unit R, the green light primary color emitting unit G, and the blue light primary color emitting unit B is merely illustrative and is not intended to limit the embodiments of this application.

[0098] Figure 3B An embodiment of this application provides a method for... Figure 3A A sectional view along the A1-A2 direction.

[0099] In some embodiments of this application, such as Figure 3B As shown, the display panel includes a driving substrate 110, a pixel definition layer (PDL), a light-emitting stack, and a first light-shielding layer 140.

[0100] The driving substrate 110 may include, for example, a substrate and a pixel driving circuit disposed on the substrate. The structure of the driving substrate 110 in related technologies is applicable to the embodiments of this application. The structure of the driving substrate 110 will be illustrated below.

[0101] Figure 4 This is a schematic diagram of a pixel delimiting layer provided in an embodiment of this application.

[0102] The pixel delimiting layer (PDL) is disposed on one side of the driving substrate 110, such as... Figure 4 As shown, the pixel delimiting layer (PDL) includes a plurality of aperture units 120 arranged in an array. Each aperture unit 120 includes a first aperture 121 and a second aperture 122, with the first aperture 121 disposed on one side of the second aperture 122 along a first direction X. Alternatively, it can be understood that the arrangement of the aperture units 120 is the same as the arrangement of the primary color light-emitting units, with one aperture unit 120 corresponding to one primary color light-emitting unit, and the arrangement of the aperture units 120 defining the arrangement of the plurality of primary color light-emitting units.

[0103] For example, in each aperture unit 120 of the pixel definition layer (PDL), a first aperture 121 is disposed along a first direction X on one side of a second aperture 122. This application embodiment does not limit the shape of the first aperture 121 and the second aperture 122. Figure 4 The image shown is for illustrative purposes only. The shapes of the first opening 121 and the second opening 122 will be explained in detail below, but will not be explained here.

[0104] In some embodiments of this application, the optical density (OD) of the pixel-defining layer (PDL) is greater than 1. For example, the optical density of the PDL is greater than 1, 1.5, 2, 2.5, 3, 3.5, etc. This can improve the absorbance of the PDL and reduce lateral diffraction between sub-pixels.

[0105] In some embodiments of this application, such as Figure 3B As shown, the inner edge of the pixel defining layer (PDL) near the opening unit 120 is a bevel. For example, the angle between the inner edge and the thickness direction of the PDL is greater than 15°. For example, the angle between the inner edge and the thickness direction of the PDL is greater than 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, etc. When light strikes the inner edge at a larger incident angle, the reflected light is more easily absorbed outside the guide panel or by the PDL itself, weakening the lateral light diffracted between sub-pixels and reducing diffraction diffusion to adjacent sub-pixels.

[0106] like Figure 3B As shown, the light-emitting stack includes multiple primary color light-emitting units 130, which are correspondingly disposed within multiple opening units 120. For example, each opening unit 120 contains one primary color light-emitting unit 130. The primary color light-emitting unit 130 includes a first sub-light-emitting unit 131 and a second sub-light-emitting unit 132 for emitting light of the same color. The first sub-light-emitting unit 131 is disposed within a first opening 121, and the second sub-light-emitting unit 132 is disposed within a second opening 122.

[0107] like Figure 3BAs shown, a first light-shielding layer 140 is disposed on the side of the plurality of primary color light-emitting units 130 away from the driving substrate 110. The first light-shielding layer 140 includes a plurality of first light-emitting openings 141, each of which includes a third opening 143 and a fourth opening 144. The third opening 143 is located on the side of the first sub-light-emitting unit 131 away from the driving substrate 110, and light emitted from the first sub-light-emitting unit 131 can pass through the third opening 143. The fourth opening 144 is located on the side of the second sub-light-emitting unit 132 away from the driving substrate 110, and light emitted from the second sub-light-emitting unit 132 can pass through the fourth opening 144.

[0108] In some embodiments of this application, the material of the first light-shielding layer 140 includes a black matrix. For example, the optical density of the first light-shielding layer 140 is greater than 1. For instance, the optical density of the first light-shielding layer 140 is greater than 1, 1.5, 2, 2.5, 3, 3.5, etc. This can improve the light absorption of the first light-shielding layer 140 and reduce lateral diffraction between sub-pixels.

[0109] In some embodiments of this application, the inner side of the first light-shielding layer 140 near the first light-emitting opening 141 is a bevel. For example, the angle between the inner side and the thickness direction of the first light-shielding layer 140 is greater than 15°. For example, the angle between the inner side and the thickness direction of the first light-shielding layer 140 is greater than 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, etc. When light strikes the inner side at a larger incident angle, the reflected light is more easily absorbed outside the guide panel or by the first light-shielding layer 140 itself, reducing diffraction and diffusion to adjacent sub-pixels.

[0110] For example, the display panel also includes an ink-jet printing (IJP) layer, which can also be called a planarization layer.

[0111] For example, the display panel also includes a chemical vapor deposition (CVD) layer, which can also be referred to as a water and oxygen barrier layer.

[0112] For example, the display panel also includes a touch panel (TP). For instance, the touch panel TP includes a first electrode layer E1, a second electrode layer E2, a first transparent adhesive layer OC1, and a second transparent adhesive layer OC2. The first transparent adhesive layer OC1 covers the first electrode layer E1, and the second transparent adhesive layer OC2 covers the second electrode layer E2. The second electrode layer E2 is disposed on the side of the first electrode layer E1 away from the driving substrate 110.

[0113] For example, the display panel also includes a touch bonding layer (TBL), which is disposed on the side of the touch stack TP facing the driving substrate 110, and is used to connect the touch stack TP to the light-emitting stack.

[0114] The specific location of the first light-shielding layer 140 in the display panel is not limited in this embodiment. The location of the first light-shielding layer 140 will be illustrated below, but will not be described here. Figure 3B This is merely an illustrative example. The first light-shielding layer 140 is disposed on the side of the touch stack TP away from the driving substrate 110. The display panel also includes a third transparent adhesive layer OC3, which covers the first light-shielding layer 140.

[0115] Figure 5A This is a top view schematic diagram of a first light-shielding layer and a pixel-defining layer provided in an embodiment of this application. Figure 5B An embodiment provided in this application Figure 5A A magnified view of a portion of point A in the middle.

[0116] In some embodiments of this application, such as Figure 5A As shown, the projection of the first opening 121 onto the driving substrate 110 has a first contour a1, the projection of the second opening 122 onto the driving substrate 110 has a second contour a2, the projection of the third opening 143 onto the driving substrate 110 has a third contour a3, and the projection of the fourth opening 144 onto the driving substrate 110 has a fourth contour a4.

[0117] For example, such as Figure 5B As shown, the third contour a3 includes a first privacy segment a31. The maximum distance h1 from the first privacy segment a31 to the first contour a1 is less than the minimum distance h2 from the fourth contour a4 to the second contour a2. The first privacy segment a31 is used to reduce the viewing angle of the first opening 121, so that the area where the first privacy segment a31 is located has a privacy protection effect.

[0118] The distances from each position of the first privacy segment a31 to the first contour a1 can be equal or unequal. Similarly, the distances from the fourth contour a4 to the second contour a2 can be equal or unequal. The maximum distance h1 from each position of the first privacy segment a31 to the first contour a1 must be less than the minimum distance h2 from the fourth contour a4 to the second contour a2. For example, the distances from each position of the first privacy segment a31 to the first contour a1 can be equal.

[0119] The distance from each position of the first privacy segment a31 to the first contour a1 is small, and the aperture ratio of the sub-pixel corresponding to the first opening 121 is relatively small, thus acting as a privacy pixel in the display panel 100. The distance from the fourth contour a4 to the second contour a2 is large, and the aperture ratio of the sub-pixel corresponding to the second opening 122 is relatively large, thus acting as a shared pixel in the display panel 100.

[0120] The embodiments of this application do not limit the number, length, or location of the first privacy segment a31 included in the third contour a3. Figure 5B This is just an illustration.

[0121] In some embodiments of this application, the maximum distance h1 from the first privacy segment a31 to the first contour a1 is less than 2 μm. For example, the maximum distance h1 from the first privacy segment a31 to the first contour a1 is less than 1.8 μm, 1.6 μm, 1.4 μm, 1.2 μm, 1.0 μm, 0.8 μm, 0.6 μm, 0.4 μm, 0.2 μm, etc. This reduces the viewing angle of the sub-pixel where the first opening 121 is located, thereby achieving privacy display.

[0122] In some embodiments of this application, the minimum distance from the fourth contour a4 to the second contour a2 is greater than or equal to 2 μm. For example, the minimum distance from the fourth contour a4 to the second contour a2 is greater than or equal to 2 μm, 2.2 μm, 2.4 μm, 2.6 μm, 2.8 μm, 3 μm, 4 μm, 5 μm, or 6 μm. This increases the viewing angle of the sub-pixel where the second opening 122 is located, enabling shared display.

[0123] In some embodiments of this application, in the same opening unit 120, the distance h5 from the first opening 121 to the second opening 122 is greater than or equal to 5 μm. For example, the distance h5 from the first opening 121 to the second opening 122 is greater than 5 μm, 6 μm, 7 μm, 8 μm, 9 μm, 10 μm, 15 μm, 20 μm, etc., to reduce lateral crosstalk between adjacent sub-pixels of the same color.

[0124] In some embodiments of this application, an isolation groove or isolation pillar may be provided between the first opening 121 and the second opening 122 to further reduce lateral crosstalk between adjacent sub-pixels of the same color.

[0125] For example, the distance h5 between the first opening 121 and the second opening 122 is less than 22 μm to improve the opening ratio. An isolation groove or isolation column may not be provided between the first opening 121 and the second opening 122 to further improve the opening ratio.

[0126] In some embodiments of this application, in two adjacent opening units 120 along a direction obliquely intersecting the first direction X (with an angle less than 90°), the distance h6 from the second opening 122 of one opening unit 120 to the first opening 121 of the other opening unit 120 is greater than or equal to 5 μm.

[0127] For example, the aforementioned distance h6 is greater than 5um, 6um, 7um, 8um, 9um, 10um, 15um, 20um, etc., to reduce lateral crosstalk between adjacent heterochromatic subpixels.

[0128] In some embodiments of this application, in two adjacent opening units 120 along a direction obliquely intersecting the first direction X, an isolation groove or isolation pillar may be provided between the second opening 122 of one opening unit 120 and the first opening 121 of the other opening unit 120, so as to further reduce the lateral crosstalk between adjacent heterochromatic sub-pixels.

[0129] For example, the aforementioned distance h6 is less than 22 μm. This is to increase the aperture ratio. In two adjacent opening units 120 along a direction oblique to the first direction X, the second opening 122 of one opening unit 120 and the first opening 121 of the other opening unit 120 may not be provided with an isolation groove or isolation column to further increase the aperture ratio.

[0130] In some embodiments of this application, the second opening 122 is strip-shaped. Therefore, the sub-pixels corresponding to the second opening 122 are strip-shaped. This can increase the width of the horizontal pixel opening, thereby improving the aperture ratio of the sub-pixels (shared pixels) corresponding to the second opening 122.

[0131] In the display panel provided in this embodiment, the pixel delimiting layer (PDL) includes a first opening 121 and a second opening 122, and sub-light-emitting units emitting the same color light are respectively disposed in the first opening 121 and the second opening 122. Therefore, the first opening 121 and the second opening 122 correspond to two sub-pixels of the display panel 100 that emit the same color light. The projections of the first opening 121, the second opening 122, the third opening 143 and the fourth opening 144 in the first light-shielding layer 140 correspond to the first contour a1, the second contour a2, the third contour a3 and the fourth contour a4, respectively. The first contour a1 has a first privacy segment a31, and the distance from the first privacy segment a31 to the first opening 121 is less than the distance from the fourth contour a4 to the second contour a2. Therefore, the viewing angle of the part corresponding to the first privacy segment a31 will be reduced, which can achieve the effect of side privacy. Then, the sub-pixel corresponding to the first opening 121 can be regarded as a privacy pixel. The distance from the fourth contour a4 to the second contour a2 is larger, which can have a better viewing angle. Therefore, the sub-pixel corresponding to the second opening 122 can be considered a shared pixel. Pixels in the display panel with two display effects can achieve two different display effects to meet the different needs of privacy display and shared display. Moreover, in this embodiment, the first opening 121 and the second opening 122 in the same unit are respectively provided with a first sub-light-emitting unit 131 and a second sub-light-emitting unit 132 emitting the same color light, and there is also a first light-shielding layer 140 for anti-crosstalk. Therefore, the gap between the first opening 121 and the second opening 122 in the same opening unit can be reduced, which helps to improve the pixel density of the display panel 100.

[0132] Figure 6A This is a cross-sectional view of a display panel provided in an embodiment of this application. Figure 6B This is a top view schematic diagram of a display panel provided in an embodiment of this application. Figure 6C An embodiment provided in this application Figure 6B A magnified view of a section at point B in the middle. Figure 6D This is a schematic diagram illustrating a privacy protection capability provided in an embodiment of this application.

[0133] In some embodiments of this application, such as Figure 6A As shown, the display panel 100 also includes a second light-shielding layer 150, which is disposed on the side of the plurality of primary color light-emitting units 130 away from the driving substrate 110 and has a gap between it and the first light-shielding layer 140.

[0134] The second light-shielding layer 150 can be disposed on the side of the first light-shielding layer 140 closer to the driving substrate 110, or it can be disposed on the side of the first light-shielding layer 140 farther from the driving substrate 110. As long as the second light-shielding layer 150 and the first light-shielding layer 140 do not contact each other, and are separated by other film layers, it is acceptable. Figure 6AThis is just an illustration.

[0135] For example, the display panel 100 also includes a fourth transparent adhesive layer OC4 and a fifth transparent adhesive layer OC5. The fourth transparent adhesive layer OC4 is disposed between the first light-shielding layer 140 and the second light-shielding layer 150 to adjust the spacing between the first light-shielding layer 140 and the second light-shielding layer 150, thereby adjusting the light-shielding angle. The fifth transparent adhesive layer OC5 covers the second light-shielding layer 150.

[0136] The second light-shielding layer 150 includes a plurality of second light-emitting openings 152, each including a seventh opening 157 and an eighth opening 158. The projection of the seventh opening 157 onto the driving substrate 110 overlaps with the projection of the third opening 143 onto the driving substrate 110. For example, the projection of the seventh opening 157 onto the driving substrate 110 covers the projection of the third opening 143 onto the driving substrate 110. Or, for example, the projection of the third opening 143 onto the driving substrate 110 covers the projection of the seventh opening 157 onto the driving substrate 110. Or, for example, the projection of the seventh opening 157 onto the driving substrate 110 overlaps with the projection of the third opening 143 onto the driving substrate 110.

[0137] Of the fourth opening 144 and the eighth opening 158, the projection of the one farther from the driving substrate 110 onto the driving substrate 110 covers the projection of the one closer to the driving substrate 110 onto the driving substrate 110 of the fourth opening 144. For example, the eighth opening 158 is farther from the driving substrate 110 than the fourth opening 144, and the projection of the eighth opening 158 onto the driving substrate 110 covers the projection of the fourth opening 144 onto the driving substrate 110. Any projection of the eighth opening 158 onto the driving substrate 110 that is greater than or equal to the projection of the fourth opening 144 onto the driving substrate 110 is considered a coverage in the embodiments of this application.

[0138] For example, such as Figure 6B As shown, the projection of the seventh opening 157 onto the driving substrate 110 has a seventh contour a7, and the projection of the eighth opening 158 onto the driving substrate 110 has an eighth contour a8.

[0139] The seventh contour a7 can be located inside the third contour a3, or outside the third contour a3. The seventh contour a7 can also coincide with the third contour a3, or intersect with the third contour a3. Figure 6B The diagram illustrates the case where the seventh contour a7 and the third contour a3 overlap.

[0140] The eighth opening 158 is farther away from the driving substrate 110 than the fourth opening 144. The eighth contour a8 can coincide with the fourth contour a4, or the eighth contour a8 can be located outside the fourth contour a4. That is, the eighth contour a8 is extended outward relative to the fourth contour a4.

[0141] By providing two spaced-apart first light-shielding layer 140 and second light-shielding layer 150 in the display panel 100, the light-shielding layer closer to the driving substrate 110 can block light at a large angle, while the light-shielding layer farther from the driving substrate 110 can block light at a small angle, thereby limiting the light emission angle and improving the privacy protection effect.

[0142] In some embodiments of this application, multiple primary color light-emitting units 130 include a first primary color light-emitting unit and a second primary color light-emitting unit, and multiple opening units 120 include a first opening unit and a second opening unit. The first primary color light-emitting unit is disposed within the first opening unit, and the second primary color light-emitting unit is disposed within the second opening unit. In the first opening unit, the maximum distance from the first privacy screen segment of the first opening to the first contour is a first distance. In the second opening unit, the maximum distance from the first privacy screen segment of the first opening to the first contour is a second distance. The first distance is less than the second distance. For example, the first primary color light-emitting unit is a blue light-emitting unit, and the second primary color light-emitting unit is a red light-emitting unit or a green light-emitting unit. That is, the first light-shielding layer has different degrees of obstruction for each primary color light-emitting unit. By combining the characteristics such as the emitted color and the aperture ratio, the mixing ratio of each primary color light can be adjusted to improve color deviation. For example, the first opening where the blue light-emitting unit is located has a larger degree of obstruction, which can reduce the amount of blue light emitted from the wide viewing angle, effectively blocking blue light from overflowing to the red light unit or the green light unit, preventing the destruction of the red, green and blue mixing ratio, and improving color deviation.

[0143] For example, the plurality of primary color light-emitting units 130 include a red light-emitting unit 130R, a green light-emitting unit 130G, and a blue light-emitting unit 130B. The red light-emitting unit 130R includes a first red sub-light-emitting unit 131-R1 and a second red sub-light-emitting unit 132-R2, with the first red sub-light-emitting unit 131-R1 disposed within a first opening 121 and the second red sub-light-emitting unit 132-R2 disposed within a second opening 122. The green light-emitting unit 130G includes a first green sub-light-emitting unit 131-G1 and a second green sub-light-emitting unit 131-G2, with the first green sub-light-emitting unit 131-G1 disposed within the first opening 121 and the second green sub-light-emitting unit 132-G2 disposed within the second opening 122. The blue light-emitting unit 130B includes a first blue sub-light-emitting unit 131-B1 and a second blue sub-light-emitting unit 132-B2, with the first blue sub-light-emitting unit 131-B1 disposed within the first opening 121 and the second blue sub-light-emitting unit 132-B2 disposed within the second opening 122.

[0144] In the first opening 121 where the blue light-emitting unit 130B is located, the maximum distance from the first privacy segment a31 to the first contour a1 is the first distance; in the first opening 121 where the red light-emitting unit 130R or the green light-emitting unit 130G is located, the maximum distance from the first privacy segment a31 to the first contour a1 is the second distance. The first distance is less than the second distance.

[0145] That is, the first light-shielding layer 140 has a large degree of blocking on the first opening 121 where the blue light-emitting unit 130B is located, which can effectively block blue light from overflowing into the red light unit or the green light unit, prevent damage to the mixing ratio of red, green and blue, and improve color deviation.

[0146] In some embodiments of this application, the area of ​​the opening unit 120 where the blue light-emitting unit 130B is located is larger than the area of ​​the opening unit 120 where the non-blue light-emitting unit is located.

[0147] By increasing the area of ​​the aperture unit 120 where the blue light-emitting unit 130B is located, the aperture ratio of the blue light-emitting unit 130B can be increased, thereby increasing the amount of blue light transmitted, so as to ensure the brightness balance of the three primary colors and improve the color life.

[0148] In some embodiments of this application, such as Figure 6B As shown, the third opening 143 and the fourth opening 144 are connected. That is, there is no light-shielding structure between the third opening 143 and the fourth opening 144; the third opening 143 and the fourth opening 144 are connected to form a large opening. This can reduce the shading range of the first light-shielding layer 140 and increase the aperture ratio of the display panel 100.

[0149] In some embodiments of this application, the seventh opening 157 and the eighth opening 158 are connected. That is, there is no light-shielding structure between the seventh opening 157 and the eighth opening 158, and the seventh opening 157 and the eighth opening 158 are connected to form a large opening. This can reduce the shading range of the second light-shielding layer 150 and increase the aperture ratio of the display panel 100.

[0150] In some embodiments of this application, such as Figure 6C As shown, the third contour a3 includes two first privacy segments a31, which are located on opposite sides of the first contour a1 along a direction intersecting the first direction X. Therefore, the two first privacy segments a31 are located on two sides of the display panel 100.

[0151] Therefore, the side where the two first privacy screen segments a31 are located can achieve the privacy display function, such as Figure 6D As shown, the display panel 100 has privacy display functionality on at least two sides.

[0152] In some embodiments of this application, the third contour a3 further includes a non-peeping segment a32, which connects the two first peeping segments a31 and is located away from the second contour a2. The minimum distance h3 from the non-peeping segment a32 to the first contour a1 is greater than or equal to the minimum distance h2 from the fourth contour a4 to the second contour a2. The distances from each position of the non-peeping segment a32 to the first contour a1 may be equal or unequal.

[0153] The minimum distance h2 between the fourth contour a4 and the second contour a2 is the minimum distance to achieve the privacy display function. If the minimum distance h3 between the non-privacy segment a32 and the first contour a1 is greater than or equal to the minimum distance h2 between the fourth contour a4 and the second contour a2, then the non-privacy segment a32 will not have a privacy display function, which can be applied to products that do not require four-sided privacy protection.

[0154] Figure 7A This is a top view schematic diagram of another display panel provided in an embodiment of this application. Figure 7B An embodiment provided in this application Figure 7A A magnified view of a section at point C. Figure 7C This is a schematic diagram illustrating another privacy protection capability provided in an embodiment of this application.

[0155] In some embodiments of this application, such as Figure 7A and Figure 7B As shown, the third contour a3 also includes a third first privacy segment a31, which is located on the side of the first contour a1 away from the second contour a2. For example, the third first privacy segment a31 connects two first privacy segments a31 located on opposite sides of the first contour a1.

[0156] The minimum distance h1 from the third first privacy segment a31 to the first contour a1 is also less than the minimum distance h2 from the fourth contour a4 to the second contour a2, so the privacy display function can also be achieved at the location of the third first privacy segment a31. Figure 7C As shown, the display panel 100 has a three-sided privacy protection function.

[0157] For example, such as Figure 7B As shown, the three first privacy segments a31 can be regarded as one long first privacy segment a31, and the distance from each position of the three first privacy segments a31 to the first contour a1 is equal.

[0158] Alternatively, for example, the three first privacy segments a31 can be regarded as one long first privacy segment a31, and the distances from the three first privacy segments a31 to the first contour a1 are not completely equal or completely unequal. Figure 7D and Figure 7E This is a schematic diagram of the structure of a single pixel provided in an embodiment of this application.

[0159] For example, such as Figure 7D As shown, the first privacy section a31 includes a portion that is concave relative to the first contour a1.

[0160] Or, for example, such as Figure 7E As shown, the first privacy section a31 includes a portion that protrudes outward relative to the first contour a1.

[0161] The embodiments of this application do not limit the specific location of the aforementioned concave or convex portions. Figure 7D and Figure 7E This is for illustrative purposes only. Regardless of whether the third opening 143 and the fourth opening 144 are connected, the first privacy segment a31 can be configured such that the distance from each location to the first contour a1 is not exactly equal.

[0162] By making the distances from each position of the first privacy segment a31 to the first contour a1 not completely equal, the privacy viewing angle can be reasonably adjusted according to the privacy requirements of different angles, so as to improve the display effect while ensuring the privacy effect.

[0163] In some embodiments of this application, such as Figure 7A As shown, the display panel 100 includes a camera area. The side of the display panel 100 closest to the camera area is the top side, and the side of the display panel 100 opposite to the top side is the bottom side. The two sides where the display panel 100 intersects with the top side and the bottom side are the left and right sides, respectively.

[0164] The top side of the display panel 100 can be understood, for example, as the upper side of the electronic device 1 when the automatic rotation function of the electronic device 1 is turned off and the user is using the electronic device 1 normally. For example, it is the side where the speaker of the electronic device 1 is located. The top side of the display panel 100 can be the long side of the display panel 100 or the short side of the display panel 100.

[0165] In some embodiments of this application, the first direction X is the direction from the bottom side to the top side.

[0166] Therefore, the first opening 121 is located on the side of the second opening 122 near the camera area, the third opening 143 is located on the side of the fourth opening 144 near the camera area, and the seventh opening 157 is located on the side of the eighth opening 158 near the camera area.

[0167] like Figure 7B As shown, in the third contour a3, the two first privacy segments a31 are located on the left and right sides of the display panel 100, which can realize privacy protection on the left and right sides of the display panel 100. When the top side of the display panel 100 also includes the first privacy segment a31, privacy protection on the top side of the display panel 100 can be realized.

[0168] In other embodiments, the first direction X can also be a direction from the top side to the bottom side, a direction from the left side to the right side, a direction from the right side to the left side, a direction from the lower left corner to the upper right corner, a direction from the lower right corner to the upper left corner, etc. The embodiments of this application do not limit this.

[0169] Figure 8A This is a top view schematic diagram of another display panel provided in an embodiment of this application. Figure 8B An embodiment provided in this application Figure 8A A magnified view of a section at point D. Figure 8C This is a schematic diagram illustrating another privacy protection capability provided in an embodiment of this application.

[0170] In some embodiments of this application, such as Figure 8A and Figure 8B As shown, the maximum distance h4 from the third contour a3 to the first contour a1 is less than the minimum distance h2 from the fourth contour a4 to the second contour a2.

[0171] Alternatively, it can be understood that the distance from each position of the third contour a3 to the first contour a1 is less than the minimum distance h2 from the fourth contour a4 to the second contour a2. Therefore, all parts of the third contour a3 belong to the first privacy segment a31. The distances from each position of the third contour a3 to the first contour a1 can be equal or unequal. For example, the distances from each position of the third contour a3 (first privacy segment a31) to the first contour a1 are equal, which simplifies the design.

[0172] Figure 8A In the middle, the third contour a3 and the seventh contour a7 coincide, while the fourth contour a4 and the eighth contour a8 do not coincide.

[0173] Therefore, the entire outline of the third contour a3 can provide privacy protection, such as Figure 8C As shown, the display panel 100 can achieve four-sided privacy protection.

[0174] Figure 9A This is a top view schematic diagram of another display panel provided in an embodiment of this application. Figure 9B An embodiment provided in this application Figure 9A A magnified view of a section at point E in the middle.

[0175] In some embodiments of this application, such as Figure 9A As shown, the opening unit 120 also includes a fifth opening 125, which is disposed on the side of the first opening 121 away from the second opening 122. The projection of the fifth opening 125 onto the driving substrate has a fifth profile a5.

[0176] The primary color light-emitting unit 130 also includes a third sub-light-emitting unit 133 that emits light of the same color as the first sub-light-emitting unit 131. The third sub-light-emitting unit 133 is disposed within the fifth opening 125.

[0177] The first light-emitting aperture 141 also includes a sixth aperture 146, which is located on the side of the third aperture 143 away from the fourth aperture 144. For example, along the first direction X, the third aperture 143, the fourth aperture 144, and the sixth aperture 146 are connected to improve the aperture ratio.

[0178] like Figure 9B As shown, the projection of the sixth opening 146 onto the driving substrate has a sixth contour a6. The maximum distance h1 from the first privacy segment a31 to the first contour a1 is less than the minimum distance h5 from the sixth contour a6 to the fifth contour a5. Therefore, the sub-pixel corresponding to the fifth opening 125 is also a shared sub-pixel.

[0179] The third contour a3 includes two first privacy segments a31, which are located on opposite sides of the first contour a1 along a direction intersecting the first direction X.

[0180] Therefore, the display panel 100 can achieve a privacy display function on the side where the first privacy segment a31 is located. Moreover, the opening unit 120 includes three openings, each corresponding to a sub-pixel, which can increase the PPI of the display panel 100.

[0181] In some embodiments of this application, the second light-shielding layer 150 of the display panel 100 further includes a ninth opening, which is correspondingly disposed with respect to the sixth opening 146. Of the two openings, the one farther from the driving substrate and the sixth opening 146, the projection of the latter onto the driving substrate covers the projection of the former closer to the driving substrate.

[0182] For example, the ninth opening is farther away from the driving substrate than the sixth opening, and the projection of the ninth opening onto the driving substrate has a ninth contour a9. The ninth contour a9 may coincide with the sixth contour a6, or the ninth contour a9 may extend outward relative to the sixth contour a6.

[0183] In some embodiments of this application, the seventh opening 157, the eighth opening 158, and the ninth opening are connected to increase the opening ratio.

[0184] Figures 10A-10C This is a top view schematic diagram of another first light-shielding layer and pixel defining layer provided in an embodiment of this application.

[0185] In some embodiments of this application, such as Figures 10A-10CAs shown, the first contour a1, the second contour a2, the third contour a3, and the fourth contour a4 are curved-edge types. For example, the edges of the above contours are curved lines without sharp corners. The diffraction intensity is uniform at all positions of the curved-edge type, resulting in a more uniform display effect.

[0186] For example, the above-mentioned arc-shaped shapes include circles, ellipses, polygons that are close to circles, polygons that are close to ellipses, or combinations of the above shapes.

[0187] For example, the fifth contour a5, the sixth contour a6, the seventh contour a7, the eighth contour a8, and the ninth contour a9 are also curved edges.

[0188] In some embodiments of this application, such as Figure 10A As shown, along a direction perpendicular to the first opening 121 to the second opening 122, the first light-emitting opening 141 has a second minimum size m6 in the portion located between the first opening 121 and the second opening 122, a fourth maximum size m4 in the portion located around the first opening 121, and a fifth maximum size m5 in the portion located around the second opening 122. The second minimum size m6 is smaller than the fourth maximum size m4 and the fifth maximum size m5. Alternatively, the first light-emitting opening 141 can be understood as being gourd-shaped.

[0189] Figure 10D This is a top view schematic diagram of a first light-shielding layer, a second light-shielding layer, and a pixel-defining layer provided in an embodiment of this application.

[0190] In some embodiments of this application, such as Figure 10D As shown, along a direction perpendicular to the first opening 121 to the second opening 122, the second light-emitting opening 152 has a first minimum size m3 in the portion located between the first opening 121 and the second opening 122, a first maximum size m1 in the portion located around the first opening 121, and a second maximum size m2 in the portion located around the second opening 122. The first minimum size m3 is smaller than the first maximum size m1 and the second maximum size m2. Alternatively, the second light-emitting opening 152 can be understood as being gourd-shaped.

[0191] The outlines of the third opening 143 and the seventh opening 157 may or may not overlap. The third opening 143 and the fourth opening 144 may or may not be connected. The seventh opening 157 and the eighth opening 158 may or may not be connected.

[0192] By reducing the size of the first light-emitting opening 141 and / or the second light-emitting opening 152 in the portion located between the first opening 121 and the second opening 122, the brightness attenuation and color transition of the privacy pixel at the lower viewing angle and the shared pixel at the upper viewing angle can be more uniform, thereby improving the display effect.

[0193] Figure 11This is a top view schematic diagram of another display panel provided in an embodiment of this application.

[0194] In other embodiments, such as Figure 11 As shown, the first contour a1, the second contour a2, the third contour a3, and the fourth contour a4 are polygons. For example, the edges of the above contours are straight lines.

[0195] For example, the fifth contour a5, the sixth contour a6, the seventh contour a7, the eighth contour a8, and the ninth contour a9 are also polygons.

[0196] The area of ​​a shape enclosed by straight sides is greater than the area of ​​a shape enclosed by curved sides. Therefore, when these contours are polygonal, the pixel aperture ratio can be increased.

[0197] The positions of the first light-shielding layer 140 and the second light-shielding layer 150 in the display panel 100 will be illustrated below.

[0198] Figures 12A-12C An embodiment of this application provides a method for... Figure 8A Sectional view along line B1-B2.

[0199] In some embodiments of this application, such as Figure 12A As shown, the display panel 100 also includes a color filter layer CF, which is disposed within a plurality of first light-emitting openings 141. For example, the color filter layer CF includes a red light filter unit r, a green light filter unit (r), and a green light filter unit (r). Figure 12A (Not shown in the diagram) and blue light filter unit b, each of the third opening 143 and the fourth opening 144 is provided with a filter unit of a different color.

[0200] For example, a red light filter unit r is disposed above the first red sub-light emitting unit 131-R1 and located within the third opening 143, and a red light filter unit r is disposed above the second red sub-light emitting unit 132-R2 and located within the fourth opening 144. A green light filter unit g is disposed above the first green sub-light emitting unit 131-G1 and located within the third opening 143, and a green light filter unit g is disposed above the second green sub-light emitting unit 132-G2 and located within the fourth opening 144. A blue light filter unit b is disposed above the first blue sub-light emitting unit 131-B1 and located within the third opening 143, and a blue light filter unit b is disposed above the second blue sub-light emitting unit 132-B2 and located within the fourth opening 144.

[0201] Taking the red light filter unit r as an example, the red light filter unit r and the first light-shielding layer 140 can be Figure 12AIn the splicing structure shown, the red light filter unit r can also overlap with the first light-shielding layer 140. For example, the red light filter unit r overlaps with the first light-shielding layer 140, or the first light-shielding layer 140 overlaps with the red light filter unit r. This application embodiment does not limit this.

[0202] This display panel 100 can be understood as a display panel using color filter on encapsulation (COE) technology, commonly known in the art. The color filter layer has high transmittance; using a color filter layer can improve the transmittance of the display panel 100.

[0203] In some embodiments of this application, the thickness of the blue light filter unit b is smaller than the thickness of the non-blue light filter unit. This increases the transmittance of blue light and improves the chromaticity lifetime.

[0204] In some embodiments of this application, the display panel 100 includes a touch stack TP, and a first light-shielding layer 140 is disposed on the side of the touch stack TP away from the driving substrate 110. The first light-shielding layer 140 is formed after the touch stack TP, so that the structure of the touch stack TP does not need to be changed, and the structural modification is minimal.

[0205] In some embodiments of this application, the second light-shielding layer 150 is disposed on the side of the first light-shielding layer 140 away from the touch stack TP. The second light-shielding layer 150 is formed after the touch stack TP, so that the structure of the touch stack TP does not need to be changed, and the structural modification is minimal.

[0206] In some embodiments of this application, such as Figure 12B As shown, the display panel also includes a third light-shielding layer 160. The second light-shielding layer 150 is disposed on the side of the first light-shielding layer 140 away from the driving substrate 110, and the third light-shielding layer 160 is disposed between the first light-shielding layer 140 and the second light-shielding layer 150.

[0207] For example, the display panel also includes a sixth transparent adhesive layer OC6, which covers the third light-shielding layer 160 and is located between the second light-shielding layer 150 and the third light-shielding layer 160.

[0208] The third light-shielding layer 160 includes a plurality of third light-emitting openings 161, the third light-emitting openings 161 including a tenth opening 162 and an eleventh opening 163.

[0209] The projection of the tenth opening 162 onto the driving substrate 110 overlaps the projection of the third opening 143 onto the driving substrate 110. The projection of the eleventh opening 163 onto the driving substrate 110 falls within the projection of the eighth opening 158 onto the driving substrate 110 and overlaps the projection of the fourth opening 144 onto the driving substrate 110. Alternatively, it can be understood that the tenth opening 162 is larger than the third opening 143, and the eleventh opening 163 is larger than the fourth opening 144 and smaller than the eighth opening 158.

[0210] like Figure 12B As shown, a first light-shielding strip o1 is located between the third opening 143 and the fourth opening 144; a second light-shielding strip o2 is located between the seventh opening 157 and the eighth opening 158; and a third light-shielding strip o3 is located between the tenth opening 162 and the eleventh opening 163. On the side closer to the privacy pixel (or the third opening 143), the third light-shielding strip o3 is farther away from the privacy pixel relative to the second light-shielding strip o2, and the first light-shielding strip o1 is closer to the privacy pixel relative to the second light-shielding strip o2. On the side closer to the shared pixel (or the fourth opening 144), the second light-shielding strip o2 is farther away from the shared pixel relative to the third light-shielding strip o3, and the first light-shielding strip o1 is closer to the shared pixel relative to the third light-shielding strip o3.

[0211] The third light-shielding layer 160 is disposed between the first light-shielding layer 140 and the second light-shielding layer 150. It is constructed by creating a tenth opening 162 and an eleventh opening 163 on the third light-shielding layer 160, with openings of different sizes than those in the second light-shielding layer 150. This staggered structure allows the light emitted by the privacy pixel to be partially blocked by the second light-shielding layer 150 and partially blocked by the third light-shielding layer 160. For example, small-angle light emitted from the privacy pixel is blocked by the second light-shielding layer 150, while large-angle light emitted is blocked by the third light-shielding layer 160. Therefore, the portion of the second light-shielding layer 150 originally used to block large-angle light can be removed, thereby reducing the size of the light-shielding strip in the second light-shielding layer 150. With the reduced size of the light-shielding strip in the second light-shielding layer 150, the light-shielding effect of the second light-shielding layer 150 on the shared pixel is reduced, which can increase the light emission angle of the shared pixel and improve brightness decay at large viewing angles in the shared state.

[0212] In some embodiments of this application, such as Figure 12C As shown, the display panel also includes a touch stack TP, which is disposed between the first light-shielding layer 140 and the second light-shielding layer 150. The touch stack TP includes an electrode layer, which is reused as a third light-shielding layer 160.

[0213] For example, the touch stack TP includes a first electrode layer E1 and a second electrode layer E2, and the first electrode layer E1 and / or the second electrode layer E2 are reused as a third light-shielding layer 160.

[0214] By reusing the electrode layer in the touch stack TP with the third light-shielding layer 160, the number of film layers in the display panel can be reduced, thereby reducing the thickness of the display panel 100 and improving the reliability of the display panel 100.

[0215] Figure 13 Another approach provided for embodiments of this application Figure 8A Sectional view along line B1-B2.

[0216] In some embodiments of this application, such as Figure 13 As shown, the second light-shielding layer 150 is disposed on the side of the touch stack TP facing the driving substrate 110. For example, the touch connection layer TBL covers the second light-shielding layer 150.

[0217] Therefore, there is no need for a separate transparent optical adhesive layer to cover the second light-shielding layer 150, which reduces the number of film layers. Furthermore, since a touch-sensitive laminate TP is spaced between the second light-shielding layer 150 and the first light-shielding layer 140, there is no need for a separate film layer to adjust the gap between the two layers, which can further reduce the thickness of the display panel 100 and improve its reliability. Simultaneously, it also allows the second sub-light-emitting unit 132 to have a larger light emission angle.

[0218] Figure 14A Another approach provided for embodiments of this application Figure 8A Sectional view along line B1-B2.

[0219] In some embodiments of this application, such as Figure 14A As shown, the display panel also includes a color filter layer CF, which is disposed within a plurality of second light-emitting openings 152 of the second light-shielding layer 150.

[0220] The color filter layer CF includes a first sub-primary color filter layer cf1 and a second sub-primary color filter layer cf2. The first sub-primary color filter layer cf1 and the second sub-primary color filter layer cf2 are respectively disposed in two adjacent seventh openings 157 and eighth openings 158 located in different second light-emitting openings 152. Along the direction of the first sub-primary color filter layer cf1 and the second sub-primary color filter layer cf2, the dimension of the second sub-primary color filter layer cf2 near the edge of the first sub-primary color filter layer cf1 to the fourth opening 144 near the edge of the first sub-primary color filter layer cf1 is greater than or equal to 0.5 μm.

[0221] Alternatively, it can be understood that the second sub-primary color filter layer cf2 extends toward the first sub-primary color filter layer cf1, and the area that belongs to the second light-shielding layer 150 is occupied by the second sub-primary color filter layer cf2.

[0222] For example, the aforementioned dimensions are greater than or equal to 1um, 1.5um, 2um, 2.5um, 3um, 3.5um, 4um, etc.

[0223] When the second sub-primary color filter layer cf2 and the fourth opening 144 are circular, the edges of the second sub-primary color filter layer cf2 and the fourth opening 144 can be understood as the points closest to the first sub-primary color filter layer cf1.

[0224] For example, Figure 14A In the image, the area outlined in bold is occupied by the second sub-primary color filter layer cf2. For example, the second sub-primary color filter layer cf2 is a red light filter unit r. Light emitted by the second red sub-emitting unit 132-R2 can pass through the red light filter unit r in the aforementioned area, but light emitted by the first blue sub-emitting unit 131-B1 cannot pass through the red light filter unit r in the aforementioned area.

[0225] The second sub-primary color filter layer cf2 extends 0.5µm further towards the first sub-primary color filter layer cf1. cf2 blocks light emitted from the light-emitting unit located below cf1, thus preventing crosstalk between different colored privacy pixels and shared pixels. However, since cf2 allows light emitted from the light-emitting unit of the shared pixel below it to pass through, this 0.5µm extension increases the light emission angle of the shared pixel, improves its brightness, and creates a more balanced proportion of different colors. This improves brightness decay and viewing angle color shift in the shared state over a wide viewing angle.

[0226] Figure 14B A cross-sectional view of another display panel provided in an embodiment of this application.

[0227] In some embodiments of this application, such as Figure 14B As shown, the display panel also includes a color filter layer CF, which is disposed on the side of the first light-shielding layer 140 away from the driving substrate 110.

[0228] The color filter layer CF includes a first part CF1, a second part CF2, and a third part CF3. The first part CF1 and the second part CF2 are respectively disposed on the light-emitting side of two adjacent first sub-light-emitting units 131 and 132 that emit different colors of light. The first part CF1 is disposed on the light-emitting side of the first sub-light-emitting unit 131 that emits the first color of light, and the second part CF2 is disposed on the light-emitting side of the second sub-light-emitting unit 132 that emits the second color of light.

[0229] The third part CF3 is positioned between the first part CF1 and the second part CF2, and the third part CF3 and the first part CF1 are used to transmit light of different colors. For example, the projection of the third part CF3 overlaps with the projection of the first light-shielding layer 140.

[0230] Alternatively, it can be understood that the third part CF3 in the color filter layer CF serves as the second light-shielding layer 150.

[0231] The third part CF3 and the first part CF1 are used to transmit different colors of light. Therefore, the light emitted by the first sub-light-emitting unit 131, which emits the first color of light, cannot pass through the third part CF3. This can block the oblique light emission from the privacy pixel where the first sub-light-emitting unit 131 is located to the dissimilar color-sharing pixel where the second sub-light-emitting unit 132 is located, thus preventing crosstalk. By using the color filter layer CF to achieve crosstalk prevention, it is not necessary to form a separate light-shielding layer, which can simplify the process and reduce the number of film layers in the display panel.

[0232] In some embodiments, such as Figure 14B As shown, the third part CF3 and the second part CF2 are used to transmit light of the same color.

[0233] In this way, the light emitted by the second sub-light-emitting unit 132 can be emitted from the third part CF3, which can improve the brightness of the shared pixel and make the proportion of different colors more balanced, thereby improving the brightness decay and viewing angle deviation of the shared state.

[0234] Figure 14C A cross-sectional view of another display panel provided in an embodiment of this application.

[0235] In other embodiments, such as Figure 14C As shown, the third part CF3 and the second part CF2 are used to transmit different colors of light. Therefore, the first part CF1, the second part CF2, and the third part CF3 are each used to transmit different colors of light.

[0236] In this way, the light emitted by the second sub-light-emitting unit 132 cannot be emitted from the third part CF3, which can block the oblique light emission from the shared pixel where the second sub-light-emitting unit 132 is located to the privacy pixel where the first sub-light-emitting unit 131 is located, thus improving the anti-crosstalk effect.

[0237] In some embodiments, the third portion CF3, near the edge of the second portion CF2, and the fourth opening 144, near the edge of the first portion CF1, have a dimension greater than or equal to 0.5 μm.

[0238] Alternatively, it can be understood that the second part CF2 extends toward the first sub-primary color filter layer CF1, and the area that belongs to the third part CF3 is occupied by the second part CF2.

[0239] For example, the aforementioned dimensions are greater than or equal to 1um, 1.5um, 2um, 2.5um, 3um, 3.5um, 4um, etc.

[0240] This is equivalent to increasing the size of the second part CF2, thereby increasing the light emission angle of the second sub-light-emitting unit 132, which can improve the brightness of the shared pixels, make the proportion of different colors more balanced, and thus improve the brightness decay and viewing angle deviation of the shared state at a large viewing angle.

[0241] Figure 15A Another method provided for embodiments of this application is along Figure 8A Sectional view along line B1-B2.

[0242] In some embodiments of this application, such as Figure 15A As shown, the touch stack TP includes an electrode layer, which is reused as a second light-shielding layer 150. The first electrode layer E1, which is closer to the driving substrate 110, can be reused as the second light-shielding layer 150, or the second electrode layer E2, which is farther from the driving substrate 110, can be reused as the second light-shielding layer 150. This application does not limit this specific application.

[0243] For example, the projection of the first light-shielding layer 140 onto the driving substrate 110 overlaps the projection of the second light-shielding layer 150 onto the driving substrate 110. Alternatively, this can be understood as the gap between adjacent openings in the first light-shielding layer 140 being larger than the gap between adjacent openings in the second light-shielding layer 150. That is, the light-shielding range of the upper first light-shielding layer 140 is larger than the light-shielding range of the lower second light-shielding layer 150, to avoid the problem of screen breakage caused by reflections from the electrode layer (second light-shielding layer 150).

[0244] For example, in the electrode layer reused as the second light-shielding layer 150, the gap between adjacent openings is greater than 3 μm. For instance, the gap between the seventh opening 157 and the eighth opening 158 (or the gap between the seventh opening 157 and the seventh opening 157) is greater than 3 μm, 3.5 μm, 34 μm, 4.5 μm, 5 μm, 5.5 μm, 8 μm, 10 μm, etc. This is equivalent to increasing the light-shielding area of ​​the electrode layer, which can reduce light leakage interference between sub-pixels emitting the same type of light.

[0245] In some embodiments of this application, such as Figure 15A As shown, the material of the dielectric layer covering the first electrode layer E1 and the second electrode layer E2 is an organic dielectric material. For example, the material of the dielectric layer includes transparent optical adhesive.

[0246] Figure 15B An embodiment of this application provides a method for... Figure 7A A sectional view along the C1-C2 direction.

[0247] In other embodiments, such as Figure 15BAs shown, the dielectric layer covering the first electrode layer E1 and the second electrode layer E2 is made of an inorganic dielectric material. For example, the dielectric layer material includes silicon nitride. For example, the touch stack TP includes a first silicon nitride layer SiN1 covering the first electrode layer E1 and a second silicon nitride layer SiN2 covering the second electrode layer E2.

[0248] Figures 16A-16C A cross-sectional view of another display panel provided in an embodiment of this application.

[0249] In some embodiments of this application, such as Figures 16A-16C As shown, the display panel 100 also includes a polarizer (POL), which is disposed close to the light-emitting surface of the display panel 100. For example, the polarizer POL is disposed on the side of the first light-shielding layer 140 and the second light-shielding layer 150 away from the driving substrate 110.

[0250] That is, based on any of the above structures, the color filter layer CF in the display panel 100 can be replaced with a polarizer POL.

[0251] Figure 17A A cross-sectional view of another display panel provided in an embodiment of this application. Figure 17B This is a top view of a first light-shielding layer and a pixel-defining layer provided in an embodiment of this application.

[0252] In some embodiments of this application, such as Figure 17A As shown, the touch stack TP includes a first electrode layer E1 and a second electrode layer E2. The first electrode layer E1 is reused as a first light-shielding layer 140, and the second electrode layer E2 is reused as a second light-shielding layer 150. The first electrode layer E1 can be disposed on the side of the second electrode layer E2 facing or away from the driving substrate 110. Figure 17A This is for illustrative purposes only.

[0253] In this architecture, the display panel 100 can include a polarizer (POL) or a color filter (CF). Figure 17A This is for illustrative purposes only.

[0254] like Figure 17B As shown, the first electrode layer E1 includes a plurality of first touch electrodes E11 and a plurality of first redundant electrodes E12, and the plurality of first touch electrodes E11 and the plurality of first redundant electrodes E12 surround a plurality of first light-emitting openings 141.

[0255] The first touch electrode E11 and the first touch electrode E12 can form a third opening 143 (or a fourth opening 144), or the first touch electrode E11 and the first redundant electrode E12 can form a third opening 143 (or a fourth opening 144). The first electrode layer E1 can be flexibly configured.

[0256] The redundant electrode E12 can be understood as being set in the first electrode layer E1, but without an electrode for transmitting touch signals.

[0257] In some embodiments of this application, similarly, the second electrode layer E2 includes a plurality of second touch electrodes and a plurality of second redundant electrodes, which surround a plurality of second light-emitting openings.

[0258] In some embodiments of this application, the first sub-light-emitting unit 131 is a single-layer light-emitting device, and the second sub-light-emitting unit 132 is also a single-layer light-emitting device.

[0259] Figure 18 This is a schematic diagram of the structure of a light-emitting unit provided in an embodiment of this application.

[0260] In other embodiments, the first sub-light-emitting unit 131 is a tandem light-emitting device, and the second sub-light-emitting unit 132 is also a tandem light-emitting device.

[0261] Taking the first sub-light-emitting unit 131 as an example, such as Figure 18 As shown, the first sub-light-emitting unit 131 includes multiple light-emitting devices connected in series. For example, the first sub-light-emitting unit 131 includes an anode AN, a hole inject layer (HIL) and / or a hole transport layer (HTL), a first organic light-emitting layer (EL) EL1, an N-type charge generation layer (CGL) N-CGL, a P-type charge generation layer P-CGL, a second organic light-emitting layer EL2, an electron transport layer (ETL) and / or an electron injection layer (EIL), and a cathode CA. The structure of the first sub-light-emitting unit 131 is merely illustrative; multilayer light-emitting devices in related technologies are applicable to the embodiments of this application.

[0262] At the same light-emitting power consumption, the stacked structure can achieve higher brightness. At the same brightness, the stacked structure can effectively reduce light-emitting power consumption. This helps to improve the lifespan of the first sub-light-emitting unit 131 and the second sub-light-emitting unit 132. When the electronic device 1 adopts a stacked structure + color filter layer CF structure, the brightness and power consumption of the display panel are also relatively superior.

[0263] Figure 19 This is a schematic diagram of a pixel driving circuit provided in an embodiment of this application.

[0264] In some embodiments of this application, the driving substrate 110 includes a substrate and a pixel driving circuit disposed on the substrate. The pixel driving circuit includes a driving module and a light emission control module. For example, in the same primary color light emission unit 130, the driving module in the pixel driving circuit coupled to the first sub-light emission unit 131 and the driving module in the pixel driving circuit coupled to the second sub-light emission unit 132 are shared.

[0265] For example, such as Figure 19 As shown, the driving substrate 110 includes a first light-emitting control module and a second light-emitting control module, which are used to receive different light-emitting control signals. In the same primary color light-emitting unit 130, the first sub-light-emitting unit 131 is coupled to the first light-emitting control module, and the second sub-light-emitting unit 132 is coupled to the second light-emitting control module.

[0266] For example, the first light-emitting control module includes a first transistor T1 and a second transistor T2, which are coupled to a first light-emitting control terminal EM1. The first transistor T1 is coupled between the positive power supply voltage terminal VDD and the driving module, and the second transistor T2 is coupled between the driving module and the first sub-light-emitting unit 131. The first sub-light-emitting unit 131 is also coupled to a negative power supply voltage terminal VSS.

[0267] The second light-emitting control module includes a third transistor T3 and a fourth transistor T4, which are coupled to the second light-emitting control terminal EM2. The third transistor T3 is coupled between the positive power supply voltage terminal VDD and the driving module, and the fourth transistor T4 is coupled between the driving module and the second sub-light-emitting unit 132. The second sub-light-emitting unit 132 is also coupled to the negative power supply voltage terminal VSS.

[0268] In privacy mode, the first light-emitting control terminal EM transmits an activation signal to control the first sub-light-emitting unit 131 to emit light. In shared mode, the second light-emitting control terminal EM transmits an activation signal to control the second sub-light-emitting unit 132 to emit light.

[0269] The embodiments of this application do not limit the specific structure of the driving module, and the structures of pixel circuit driving modules in related technologies are all applicable to the embodiments of this application.

[0270] Figure 20 This is a schematic diagram of the structure of a photomask provided in an embodiment of this application.

[0271] This application also provides a mask, such as... Figure 20As shown, the full face mask (FFM) includes a body, multiple rows of first openings, and multiple rows of second openings. Along a first direction X, the multiple rows of first and second openings are alternately arranged. Along the first direction X, the distance s1 from the first opening to the second opening is greater than the distance s2 from the second opening to the first opening. The first direction X intersects the row direction.

[0272] For example, the first and second openings with a distance of s2 can be understood as a repeating unit, and the spacing between the repeating units is a distance of s1.

[0273] In some embodiments of this application, the outlines of the first and second openings are curved. For example, the edges of the outlines of the first and second openings are curved lines without sharp corners. The diffraction intensity is uniform at all locations with curved edges, resulting in a more uniform display effect.

[0274] For example, the above-mentioned arc-shaped shapes include circles, ellipses, polygons that are close to circles, polygons that are close to ellipses, or combinations of the above shapes.

[0275] In some embodiments of this application, along the first direction X, the distance s2 from the second opening to the first opening is greater than or equal to 5 μm. The aforementioned distance s2 is greater than 5 μm, 6 μm, 7 μm, 8 μm, 9 μm, 10 μm, 15 μm, 20 μm, etc.

[0276] This application also provides an electronic device 1 that can automatically switch between a sharing mode and a privacy mode.

[0277] In the first display mode, the display panel of electronic device 1 displays the image from a first viewing angle. The first display mode may be, for example, a wide-viewing-angle shared mode. While electronic device 1 is displaying in the first display mode, it checks whether preset conditions for displaying in the second display mode are met. When electronic device 1 determines that the preset conditions are met, it automatically switches from the first display mode to the second display mode.

[0278] In the second display mode, the display panel shows the image from a second perspective. The first perspective is wider than the second perspective. The second display mode could be, for example, a narrow-view privacy mode.

[0279] During the process of displaying in the second display mode, the electronic device 1 detects whether the conditions for displaying in the second display mode are met. When the electronic device 1 determines that the preset conditions are not met, the electronic device 1 automatically switches back from the second display mode to the first display mode.

[0280] In this embodiment, the electronic device 1 has the function of automatically switching display modes. The preset conditions may be, for example, determining whether privacy display is required. If the preset conditions are not met, privacy display is not required, and the electronic device 1 enters the first display mode for shared display. After the preset conditions for privacy display are met, the electronic device 1 automatically switches to the second display mode for privacy display.

[0281] In some embodiments of this application, the preset conditions may include at least one of the following: the number of faces is greater than 1 or the number of eyes is greater than 1; there is a non-pre-stored user; there is a face or eye with an angle greater than a preset angle with the electronic device; the user confirms entering the second display mode; the mode switching function is enabled; and the anti-peeping application is started.

[0282] For example, electronic device 1 can identify more than one face or more than one eye using a visual sensor. For instance, an angle sensor can determine whether there is a face or eye at an angle greater than a preset angle to the electronic device. Pre-stored users can be, for example, whitelisted users pre-stored in electronic device 1. User confirmation to enter the second display mode can be, for example, an instruction triggered by a secondary confirmation step. Enabling the mode switching function can be, for example, an instruction triggered by the user triggering the target control on the user interface to activate the privacy display function. The privacy application can be, for example, a whitelisted application pre-marked by the user.

[0283] In some embodiments of this application, for example, if any one of the preset conditions is met, the electronic device 1 can switch from a first display mode to a second display mode.

[0284] For example, if more than one face or more than one eye is detected, the system switches from the first display mode to the second display mode. If a non-pre-stored user is detected, the system switches from the first display mode to the second display mode. If a face or eye with an angle greater than a preset angle to the electronic device is detected, the system switches from the first display mode to the second display mode. If the user confirms entry into the second display mode, the system switches from the first display mode to the second display mode.

[0285] In some embodiments of this application, for example, electronic device 1 will switch from a first display mode to a second display mode only after multiple preset conditions are met.

[0286] For example, if more than one face or more than one eye is detected, and a non-pre-stored user is detected, the system switches from the first display mode to the second display mode. If more than one face or more than one eye is detected, and the face or eye is at an angle greater than a preset angle to the electronic device, the system switches from the first display mode to the second display mode. If a non-pre-stored user is detected, and the face or eye is at an angle greater than a preset angle to the electronic device, the system switches from the first display mode to the second display mode. If more than one face or more than one eye is detected, and the user confirms entering the second display mode, the system switches from the first display mode to the second display mode. If more than one face or more than one eye is detected, and a non-pre-stored user is detected, and the face or eye is at an angle greater than a preset angle to the electronic device, the system switches from the first display mode to the second display mode.

[0287] The electronic device 1 provided in this application embodiment has a first display mode and a second display mode. By setting preset conditions, the electronic device 1 can automatically switch between the first display mode and the second display mode depending on whether the preset conditions are met. For example, if the first display mode is a sharing mode and the second display mode is a privacy mode, the electronic device 1 can intelligently switch between the privacy mode and the sharing mode to improve the user experience. Furthermore, if there are multiple preset conditions, the mode is switched only when all preset conditions are met, which can improve the accuracy of the judgment conclusion.

[0288] Figure 21 and Figure 22 This is a schematic diagram of the user interface of an electronic device provided in an embodiment of this application.

[0289] In some embodiments of this application, such as Figure 21 As shown, electronic device 1 displays a first user interface (UI) through a display panel. The first user interface includes a target control, which is used to enable the privacy display function.

[0290] For example, the target control for activating the privacy display function can be displayed in the same user interface as the target control for activating the mobile network and the target control for activating Bluetooth. The user can control the electronic device 1 to turn the privacy display function on or off by clicking the target control.

[0291] In some embodiments of this application, such as Figure 22 As shown, electronic device 1 displays a second user interface via a display panel. The second user interface includes a target prompt box, which prompts the user whether to enter the second display mode.

[0292] For example, the target prompt box may display the message: "Warning: Your phone is at risk of being spied on. Do you want to enable anti-spy mode?" Users can issue the command by clicking "Yes," or the command can be issued automatically after a countdown timer. This application embodiment does not limit this approach.

[0293] This application also provides a display driving method, which is executed in an electronic device.

[0294] Electronic device 1 displays an image from a first perspective in a first display mode. When preset conditions are met, electronic device 1 switches from the first display mode to a second display mode, displaying an image from a second perspective, where the first perspective is larger than the second perspective. In some embodiments of this application, the preset conditions include at least one of the following: the number of faces is greater than 1 or the number of eyes is greater than 1; there is a non-pre-stored user; there is a face or eye with an angle greater than a preset angle with electronic device 1; the user confirms entering the second display mode; the mode switching function is enabled; and the anti-peeping application is started.

[0295] In some embodiments of this application, electronic device 1 receives a first operation input by a user.

[0296] For example, the first operation is used to enable the privacy display function. For instance, when a user clicks the target control for enabling the privacy display function on the first user interface, the electronic device 1 receives the first operation input by the user and enables the privacy display function accordingly.

[0297] Alternatively, as an example, the first operation is used to initiate applications that require pre-tagged privacy displays.

[0298] For example, when a user launches an application that is pre-marked as requiring privacy, electronic device 1 will receive the first user input. If another application is launched, electronic device 1 may receive a second user input. Based on the different inputs, electronic device 1 will provide different responses. For example, upon receiving the first input, the privacy display function will be activated. Upon receiving the second input, the privacy display function will not be activated.

[0299] Users can pre-mark applications that require privacy protection. Once an application marked for privacy protection (such as online banking / memos) is launched, the privacy protection function will automatically be activated. In other words, once electronic device 1 receives the first operation to launch a pre-marked application requiring privacy protection, the privacy protection function will automatically be enabled. For example, even if the user does not click the target control to activate the privacy protection function on the primary user interface, but the user clicks to enter the pre-marked software, electronic device 1 will still enter the subsequent process of determining whether the preset conditions are met.

[0300] Alternatively, for example, the first operation is used to enable the privacy display feature and launch pre-tagged applications that require privacy.

[0301] The smart privacy feature will only be activated after the user performs the first action of enabling the privacy display feature and launching the pre-marked applications that need privacy protection. For example, if the user only enables the privacy display feature but does not launch the pre-marked applications, the subsequent process of determining whether the preset conditions are met will not be executed.

[0302] For example, after a user enables the privacy screen function, the electronic device determines whether to launch an application that is pre-marked as requiring privacy screen display. If the pre-marked application is launched, it determines whether the number of eyeballs is greater than one pair or the number of faces is greater than one. If more than one pair of eyeballs or more than one face are detected, it determines whether there is a non-pre-stored user. If a non-pre-stored user exists, it determines whether the angle between the non-pre-stored user's eyeballs or face and the electronic device 1 is greater than a preset angle. If the angle is less than the preset angle, it is determined that the user is actively sharing the privacy screen and there is no need to enter privacy mode. If the angle is greater than the preset angle, it is determined that this is a scenario of an insecure user spying, and the phone interface prompts the user to activate privacy mode. Privacy mode is activated only after the user confirms. Alternatively, privacy mode can be activated directly.

[0303] Figure 23 This is a schematic diagram illustrating the angle between a person's face orientation and an electronic device, provided as an embodiment of this application.

[0304] For example, such as Figure 23 As shown, using the virtual normal perpendicular to the display surface of electronic device 1 as a reference line, if the angle W between the face and the normal is greater than a preset angle, it is determined that there is a risk of being spied on, and subsequent operations are performed. If the angle W between the face and the normal is less than or equal to the preset angle, it is determined that active sharing is enabled, and the sharing mode is maintained. W can be, for example, equal to 10°, 20°, 30°, 40°, etc. W can be any value from 0° to 90°, and the angle can be customized according to the user's pre-stored usage habits, or set to a fixed value according to the size of electronic device 1 and the user's common scenarios.

[0305] The electronic device 1 provided in this application embodiment includes, for example, a display panel, one or more processors, and one or more memories. The one or more memories are coupled to the one or more processors, and the one or more memories are used to store computer program code, which includes computer instructions. The one or more processors execute the computer program code, causing the electronic device 1 to automatically switch between a shared mode and a privacy mode.

[0306] The display panel, also known as the display module, may include, for example, any of the display panels 100 described above in the embodiments of this application.

[0307] Figure 24This is a schematic diagram of the architecture of an electronic device provided in an embodiment of this application.

[0308] This application also provides an electronic device, such as... Figure 24 As shown, the electronic device 1 includes a drive controller 300 and a display module 400. The display panel 100 in the display module 400 includes a first primary color light-emitting unit 1100 and a second primary color light-emitting unit 1200. The second primary color light-emitting unit 1200 is farther away from the center of the display panel 100 relative to the first primary color light-emitting unit 1100.

[0309] For example, the row containing the second primary color light-emitting unit 1200 is farther from the center of the display panel 100 than the row containing the first primary color light-emitting unit 1100. Or, for example, the column containing the second primary color light-emitting unit 1200 is farther from the center of the display panel 100 than the column containing the first primary color light-emitting unit 1100.

[0310] For example, the second primary color light-emitting unit 1200 is in a different row and a different column than the first primary color light-emitting unit 1100. The center of the display panel 100 can be understood, for example, as the center of the array of primary color light-emitting units arranged in the effective display area.

[0311] The first primary color light-emitting unit 1100 may be a primary color light-emitting unit located at the center of the display panel 100, or it may not be a primary color light-emitting unit located at the center of the display panel 100.

[0312] The first primary color light-emitting unit 1100 includes a first sub-light-emitting unit 1110 and a second sub-light-emitting unit 1120 for emitting light of the same color. The second primary color light-emitting unit 1200 includes a third sub-light-emitting unit 1210 and a fourth sub-light-emitting unit 1220 for emitting light of the same color. The display panel 100 can be a display panel that includes two display modes: a privacy mode and a sharing mode. In the privacy mode, the first sub-light-emitting unit 1110 and the third sub-light-emitting unit 1210 emit light. In the sharing mode, the second sub-light-emitting unit 1120 and the fourth sub-light-emitting unit 1220 emit light.

[0313] For example, the display panel can be any of the display panels 100 described above, and the drive controller 300 is a SOC. The display module 400 may also include, for example, a display driver integrated circuit 200, which is a DDIC.

[0314] The drive controller 300 is used to receive first image data; the first image data includes first grayscale data corresponding to the first primary color light-emitting unit 1100 and second grayscale data corresponding to the second primary color light-emitting unit 1200; both the first grayscale data and the second grayscale data represent the first grayscale. That is, the first primary color light-emitting unit 1100 and the second primary color light-emitting unit 1200 display the same grayscale.

[0315] In the third display mode, the drive controller 300 outputs a first image signal based on the first image data, and the display module 400 drives the first sub-light-emitting unit 1110 and the third sub-light-emitting unit 1210 to emit light in response to the first image signal. The third display mode can be understood, for example, as the electronic device 1 entering a privacy mode.

[0316] For example, the viewing angle perpendicular to the screen of electronic device 1 is the orthogonal viewing angle (or 0° viewing angle). Under the orthogonal viewing angle, the luminous brightness of the first sub-light-emitting unit 1110 is the first brightness, and the luminous brightness of the third sub-light-emitting unit 1210 is the second brightness.

[0317] In the fourth display mode, the drive controller 300 outputs a second image signal based on the first image data, and the display module 400 drives the second sub-light-emitting unit 1120 and the fourth sub-light-emitting unit 1220 to emit light in response to the second image signal. The fourth display mode can be understood, for example, as the electronic device 1 entering a shared mode.

[0318] From a positive viewing angle, the luminous intensity of the second sub-light-emitting unit 1120 is the third brightness, and the luminous intensity of the fourth sub-light-emitting unit 1220 is the fourth brightness.

[0319] The second brightness is greater than the first brightness, and the fourth brightness is equal to the third brightness. Alternatively, in the first display mode, when receiving the same grayscale data, the brightness of the fourth sub-light-emitting unit 1220 located at the edge will be greater than the brightness of the second sub-light-emitting unit 1120 located closer to the center. However, in the second display mode, when receiving the same grayscale data, the brightness of the third sub-light-emitting unit 1210 located at the edge will be equal to or approximately equal to the brightness of the first sub-light-emitting unit 1110 located closer to the center.

[0320] In the first display mode, the electronic device 1 increases the brightness of the third sub-light-emitting unit 1210 located at the edge. The brightness of the first sub-light-emitting unit 1110, which is relatively close to the center, is not increased, or is increased by a relatively small amount.

[0321] In the second display mode, the electronic device 1 either does not increase the brightness of the fourth sub-light-emitting unit 1220 located at the edge and the brightness of the second sub-light-emitting unit 1120 located relatively close to the center, or increases it by the same amount.

[0322] For example, the first, third, and fourth luminous brightness are equal. In the first display mode, electronic device 1 does not increase the luminous brightness of the first sub-luminous unit 1110. In the second display mode, electronic device 1 does not increase the luminous brightness of the second sub-luminous unit 1120 and the fourth sub-luminous unit 1220.

[0323] Alternatively, for example, the first luminous intensity is greater than the third and fourth luminous intensities. In the first display mode, the electronic device 1 increases the luminous intensity of the first sub-luminous unit 1110. In the second display mode, the electronic device 1 does not increase the luminous intensity of the second sub-luminous unit 1120 and the fourth sub-luminous unit 1220.

[0324] For an electronic device 1 with two display modes, sharing mode and privacy mode, in privacy mode, the brightness of the display panel 100 decreases rapidly as the viewing angle increases, leading to a greater difference in brightness between the left and right eyes within the human eye's field of vision, thus increasing the strain on the binocular muscles. Furthermore, after the viewed image passes through the visual nerves and brain, the brain has difficulty fusing the image, resulting in dizziness and tension. Additionally, in privacy mode, the user has a certain viewing angle when looking at the edges of the display panel 100, resulting in visually lower edge brightness. In sharing mode, this issue of lower edge brightness is not obvious or nonexistent. This leads to a sudden change in edge brightness when switching between privacy mode and sharing mode. This embodiment of the application reduces the problem of visually lower edge brightness by specifically increasing the luminous brightness of the primary color light-emitting units far from the center of the display panel 100 in the third display mode (privacy mode). This reduces the difference in brightness between the two eyes, improves dizziness, and optimizes the brightness difference problem during mode switching. For example, it can reduce the difference in luminous brightness within a 0-30° viewing angle. In some embodiments, such as... Figure 24 As shown, the display panel 100 also includes a third primary color light-emitting unit 1300, which is located away from the center of the display panel 100 relative to the second primary color light-emitting unit 1200. The third primary color light-emitting unit 1300 includes a fifth sub-light-emitting unit 1310 and a sixth sub-light-emitting unit 1320 for emitting light of the same color.

[0325] The first image data also includes third grayscale data corresponding to the third primary color emitting unit 1300, and the third grayscale data represents the first grayscale.

[0326] The display module 400 is also used to drive the fifth sub-light-emitting unit 1310 to emit light in response to the first image signal. At a normal viewing angle, the brightness of the fifth sub-light-emitting unit 1310 is the fifth brightness level.

[0327] The ratio of the fifth luminance to the first luminance is greater than the ratio of the second luminance to the first luminance. Alternatively, this can be understood as follows: at the same grayscale, the further away from the center of the display panel the sub-light-emitting unit, the greater the brightness increase. The further away from the center of the display panel, the lower the perceived brightness. Therefore, the greater the brightness increase of the sub-light-emitting unit, the better the uniformity of brightness between the left and right eyes. Sub-light-emitting units equidistant from the center of the display panel can, for example, have the same brightness increase.

[0328] For example, the display module 400 is also used to drive the sixth sub-light-emitting unit 1320 to emit light in response to the second image signal. At a normal viewing angle, the brightness of the sixth sub-light-emitting unit 1320 is equal to the brightness of the third and fourth sub-light-emitting units.

[0329] In some embodiments, the first image signal output by the drive controller 300 includes a first grayscale signal corresponding to the first sub-light-emitting unit 1110 and a second grayscale signal corresponding to the third sub-light-emitting unit 1210. The first grayscale signal represents the second grayscale, the second grayscale signal represents the third grayscale, and the third grayscale is greater than the second grayscale.

[0330] For example, in the third display mode, after receiving the first image data, the drive controller 300 performs upscaling processing on the second grayscale data corresponding to the third sub-light-emitting unit 1210. The received data is the first grayscale, and the output is the third grayscale. Similarly, for the first grayscale data corresponding to the first sub-light-emitting unit 1110, the received data is the first grayscale, and the output is the second grayscale.

[0331] For a sub-light-emitting unit in one or more primary color light-emitting units located in the center area of ​​the display panel, no grayscale enhancement processing is required. In this case, for example, the second grayscale is equal to the first grayscale.

[0332] For a sub-light-emitting unit in one or more primary color light-emitting units located in the center area of ​​the display panel, grayscale enhancement processing can also be performed. In this case, for example, the second grayscale is greater than the first grayscale and less than the third grayscale.

[0333] For example, in the fourth display mode, after receiving the first image data, the drive controller 300 does not perform any enhancement processing on the first grayscale data of the corresponding second sub-light-emitting unit 1120 and the second grayscale data of the corresponding fourth sub-light-emitting unit 1220. What is received is the first grayscale, and what is output is still the first grayscale.

[0334] By boosting the grayscale using the drive controller 300, the brightness of the sub-light-emitting units located far from the center of the display panel can be increased.

[0335] In some embodiments, the display driver integrated circuit 200 is configured to send a first data voltage to the first sub-light-emitting unit 1110 and a second data voltage to the third sub-light-emitting unit 1210 in response to the first image signal.

[0336] The first data voltage and the second data voltage are different. The relative magnitudes of the first data voltage and the second data voltage depend on whether the driving transistor in the pixel circuit used to drive the sub-light-emitting unit is an N-type transistor or a P-type transistor.

[0337] The display panel 100 is used to drive the first sub-light-emitting unit 1110 and the third sub-light-emitting unit 1210 to emit light in response to the first data voltage and the second data voltage, ultimately achieving a brightness of the third sub-light-emitting unit 1210 greater than that of the first sub-light-emitting unit 1110. For example, in the third display mode, after receiving the first image data, the drive controller 300 sends the first image signal to the display driver integrated circuit 200. The display driver integrated circuit 200 processes the received first image signal so that the second data voltage can drive the brightness of the third sub-light-emitting unit 1210 to increase.

[0338] For example, in the fourth display mode, a third data voltage is sent to both the second sub-light-emitting unit 1120 and the fourth sub-light-emitting unit 1220 in response to the second image signal. The third data voltage may be equal to the first data voltage. In the fourth display mode, the display driver integrated circuit 200 does not perform target driving processing on the received second image signal.

[0339] By adjusting the data voltage through the display driver integrated circuit 200, the brightness of the sub-light-emitting unit located far from the center of the display panel can be increased.

[0340] This application embodiment also provides a driving method for an electronic device. The electronic device 1 includes a driving controller 300 and a display module 400. The display panel 100 in the display module 400 includes a first primary color light-emitting unit 1100 and a second primary color light-emitting unit 1200. The second primary color light-emitting unit 1200 is far away from the center of the display panel 100 relative to the first primary color light-emitting unit 1100. The first primary color light-emitting unit 1100 includes a first sub-light-emitting unit 1110 and a second sub-light-emitting unit 1120 for emitting light of the same color. The second primary color light-emitting unit 1200 includes a third sub-light-emitting unit 1210 and a fourth sub-light-emitting unit 1220 for emitting light of the same color.

[0341] The drive controller 300 receives first image data; the first image data includes first grayscale data corresponding to the first primary color light-emitting unit and second grayscale data corresponding to the second primary color light-emitting unit; both the first grayscale data and the second grayscale data represent the first grayscale.

[0342] In the third display mode, the drive controller 300 outputs a first image signal based on the first image data, and the display module 400 responds to the first image signal by driving the first sub-light-emitting unit and the third sub-light-emitting unit to emit light; at a normal viewing angle, the luminous brightness of the first sub-light-emitting unit is the first brightness, and the luminous brightness of the third sub-light-emitting unit is the second brightness.

[0343] In the fourth display mode, the drive controller 300 outputs a second image signal according to the first image data, and the display module 400 responds to the second image signal to drive the second sub-light-emitting unit and the fourth sub-light-emitting unit to emit light; the luminous brightness of the second sub-light-emitting unit is the third brightness, and the luminous brightness of the fourth sub-light-emitting unit is the fourth brightness.

[0344] The second brightness is greater than the first brightness, and the fourth brightness is equal to the third brightness.

[0345] In some embodiments, the display panel 100 further includes a third primary color light-emitting unit 1300, which is located away from the center of the display panel 100 relative to the second primary color light-emitting unit 1200; the third primary color light-emitting unit 1300 includes a fifth sub-light-emitting unit 1310 and a sixth sub-light-emitting unit 1320 for emitting light of the same color.

[0346] The first image data also includes third grayscale data corresponding to the third primary color emitting unit 1300; the third grayscale data represents the first grayscale.

[0347] The display module 400 also responds to the first image signal by driving the fifth sub-light-emitting unit 1310 to emit light; at a normal viewing angle, the luminance of the fifth sub-light-emitting unit 1310 is the fifth luminance. The ratio of the fifth luminance to the first luminance is greater than the ratio of the second luminance to the first luminance.

[0348] In some embodiments, the first image signal output by the drive controller 300 includes a first grayscale signal corresponding to the first sub-light-emitting unit 1110 and a second grayscale signal corresponding to the third sub-light-emitting unit 1210; the first grayscale signal represents the second grayscale, the second grayscale signal represents the third grayscale, the third grayscale is greater than the second grayscale, and the second grayscale is greater than or equal to the first grayscale.

[0349] In some embodiments, the display module 400 includes a display driver integrated circuit 200 and a display panel 100. In response to a first image signal, the display driver integrated circuit 200 sends a first data voltage to a first sub-light-emitting unit 1110 and a second data voltage to a third sub-light-emitting unit 1210; the first data voltage and the second data voltage are different. In response to the first data voltage and the second data voltage, the display panel 100 drives the first sub-light-emitting unit 1110 and the third sub-light-emitting unit 1210 to emit light.
