Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display panel and display device. Background Technology

[0002] With the increasing penetration of display terminals in business offices, portable devices, and smart cockpits, preventing screen information leakage has become one of the core demands of the industry, and switchable privacy display technology has become a research and development focus.

[0003] Currently, switchable privacy display panels typically include shared pixels and privacy pixels. The privacy pixels consist of a light-emitting element and a light-shielding part located on the light-emitting side of the element. The light-shielding part blocks the wide-viewing-angle light from the light-emitting element to achieve a privacy effect. However, the overlap width of the orthographic projection of the light-shielding part and the light-emitting element on the horizontal plane is consistent in all directions. All lateral viewing angles are blocked to the same degree, making it unsuitable for application scenarios where privacy is only required in a specific direction while normal visibility is maintained in other directions. Summary of the Invention

[0004] This application provides a display panel and display device to at least meet the needs of usage scenarios where privacy protection is required only from a specific direction.

[0005] To achieve the above objectives, according to a first aspect of this application, a display panel is provided, comprising: Substrate; and Multiple privacy pixels are located on the substrate. Each privacy pixel includes a first light-emitting device and a first light-shielding part located on the light-emitting side of the first light-emitting device. The first orthographic projection of the first light-emitting device on the substrate and the second orthographic projection of the first light-shielding part on the substrate have a first overlapping area in a first direction. The first overlapping area has a first size in the first direction. Wherein, the first orthographic projection and the second orthographic projection do not overlap in the second direction; or, the first orthographic projection and the second orthographic projection have a second overlapping area in the second direction, the second overlapping area has a second size in the second direction, and the second size is smaller than the first size; the second direction and the first direction extend from the geometric center of the first orthographic projection to the edge, respectively.

[0006] In some embodiments, in the second direction, the first edge of the first orthographic projection and the second edge of the second orthographic projection near the geometric center of the first orthographic projection coincide.

[0007] In some embodiments, the first edge of the first orthographic projection in the second direction is located between the second edge of the second orthographic projection in the second direction, which is close to the geometric center of the first orthographic projection, and the geometric center.

[0008] In some embodiments, the first direction and the second direction are opposite to each other.

[0009] In some embodiments, the first orthographic projection and the second orthographic projection have a third overlapping region in a third direction, the third overlapping region having a third dimension equal to the first dimension in the third direction; in a fourth direction, the third edge of the first orthographic projection and the fourth edge of the second orthographic projection near the geometric center of the first orthographic projection coincide; the fourth direction and the third direction extend from the geometric center of the first orthographic projection toward the edge respectively; the third direction and the first direction are opposite to each other, and the fourth direction and the second direction are opposite to each other.

[0010] In some embodiments, the first orthographic projection is circular in shape, and includes a first arc-shaped edge and a second arc-shaped edge that are arranged opposite to each other and connected end to end; the first light-shielding portion has a first opening, and the third orthographic projection of the first opening on the substrate includes a third arc-shaped edge and a fourth arc-shaped edge that are arranged opposite to each other and connected end to end, the third arc-shaped edge and the first arc-shaped edge coincide, and the distance between the fourth arc-shaped edge and the second arc-shaped edge gradually decreases from the midpoint of the fourth arc-shaped edge to both ends.

[0011] In some embodiments, the first orthographic projection is circular; the first light-shielding portion has a first opening, and the third orthographic projection of the first opening on the substrate is elliptical, with the geometric center of the third orthographic projection coinciding with the geometric center of the first orthographic projection.

[0012] In some embodiments, the width of the first light-emitting device is A, the first dimension is D1, the distance between the first light-shielding part and the first light-emitting device is H1, and the thickness of the first light-shielding part is H2, wherein D1≥A-(H1+H2).

[0013] In some embodiments, the privacy pixel further includes a second light-blocking portion and a color block, the second light-blocking portion being located between the first light-blocking portion and the first light-emitting device, the second light-blocking portion having a second opening that exposes the first light-emitting device, and the color block being disposed within the second opening.

[0014] According to a second aspect of this application, a display device is provided, including a display panel as described in any embodiment of the first aspect.

[0015] In the display panel of this application embodiment, since the overlap width (i.e., the first dimension) of the first orthographic projection and the second orthographic projection in the first direction is greater than their overlap width in the second direction, the privacy protection effect of the privacy pixel in the first direction is better than that in the second direction. In other words, the privacy pixel can be used to achieve directional privacy protection in at least one direction including the first direction, while not providing privacy protection in at least one direction including the second direction. This allows the display panel to adapt to usage scenarios where privacy protection in only a specific direction is required, thereby improving the user experience.

Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0020] Some embodiments of this application provide a display panel, such as Figure 1 As shown, the display panel 100 has a display area AA and a non-display area NA located on at least one side of the display area AA. The non-display area NA may, for example, surround the display area AA. The display area AA is provided with a plurality of pixel units PU, which may, for example, be arranged in an array.

[0021] like Figure 2 As shown, the display panel 100 includes a substrate SUB and a plurality of shared pixels 10 and a plurality of privacy pixels 20 located on the substrate SUB. When the privacy pixels 20 are turned on and the shared pixels 10 are turned off, the display panel 100 is in privacy mode; when at least the shared pixels 10 are turned on, the display panel 100 is in sharing mode.

[0022] In some examples, a red shared pixel R1, a green shared pixel G1, a blue shared pixel B1, at least one red privacy pixel R2, at least one green privacy pixel G2, and at least one blue privacy pixel B2 together constitute a pixel unit PU. This allows for the display of a color image in both privacy mode and shared mode.

[0023] In some examples, the area of ​​the shared pixel 10 is larger than the area of ​​the privacy pixel 20, thereby giving the display panel 100 a relatively high brightness in the sharing mode, thus improving the display effect in the sharing mode.

[0024] like Figure 3 As shown, each privacy pixel 20 includes a first light-emitting device LD1 and a first light-shielding part LS1 located on the light-emitting side of the first light-emitting device LD1. The first light-shielding part LS1 uses the wide-viewing-angle light of the first light-emitting device LD1 to achieve the privacy function of the privacy pixel 20. Each shared pixel 10 includes a second light-emitting device LD2. The light-emitting side of the second light-emitting device LD2 does not have the first light-shielding part LS1, so it has a relatively larger viewing angle.

[0025] In some examples, please refer to [link / reference]. Figure 3The privacy pixel 20 also includes a second light-shielding part LS2 and a color resist block CF. The second light-shielding part LS2 is located between the first light-shielding part LS1 and the first light-emitting device LD1. The second light-shielding part LS2 has a second opening K2 that exposes the first light-emitting device LD1, and the color resist block CF is disposed within the second opening K2. The color resist block CF is used to filter the light emitted by the first light-emitting device LD1, allowing light of a specific color to pass through. For example, Figure 3 The red privacy pixel R2 is shown. The color resist block CF is a red color resist block. The light emitted by the first light-emitting device LD1 is only red light emitted after passing through the red color resist block, thus enabling the red privacy pixel R2 to emit red light.

[0026] In some examples, the first light-shielding portion LS1 has a first opening K1, the orthographic projection of the first opening K1 onto the substrate SUB being within the range of the orthographic projection of the second opening K2 onto the substrate SUB. In other words, the orthographic projection of the first light-shielding portion LS1 onto the substrate SUB and the orthographic projection of the color resist CF onto the substrate SUB have an overlapping area around the perimeter, and this overlapping area is a continuously closed pattern.

[0027] In some examples, the shared pixel 10 includes a second light-emitting device LD2 and a third light-shielding part LS3, with the third light-shielding part LS3 and the second light-shielding part LS2 disposed on the same layer. This allows the third light-shielding part LS3 and the second light-shielding part LS2 to be manufactured using the same process, thereby improving the manufacturing efficiency of the display panel 100. The third opening K3 of the third light-shielding part LS3 exposes the second light-emitting device LD2. A color resist block corresponding to the shared pixel 10 is provided within the third opening K3 to filter the light emitted by the second light-emitting device LD2, allowing light of a specific color to be emitted. When the area of ​​the shared pixel 10 is larger than the area of ​​the privacy pixel 20, the size of the second light-emitting device LD2 is larger than the size of the first light-emitting device LD1. Correspondingly, the size of the third opening K3 is also larger than the size of the second opening K2.

[0028] In some examples, the first light-emitting device LD1 and the second light-emitting device LD2 can be organic light-emitting diodes (OLEDs), which include an anode, a light-emitting layer, and a cathode stacked sequentially. The light-emitting layers of the first light-emitting device LD1 and the second light-emitting device LD2 can be fabricated simultaneously. For example, the light-emitting layers can be fabricated using inkjet printing or vapor deposition.

[0029] In some examples, the display panel 100 also includes a pixel circuit layer that drives the privacy pixel 20 and the shared pixel 10 to emit light. The pixel circuit layer is located between the substrate and the light-emitting devices (first light-emitting device LD1 and second light-emitting device LD2) and is connected to the first light-emitting device LD1 and the second light-emitting device LD2, respectively.

[0030] In some embodiments, such as Figures 3 to 6 As shown, the first orthographic projection of the first light-emitting device LD1 on the substrate SUB and the second orthographic projection of the first light-shielding part LS1 on the substrate SUB have a first overlapping area in the first direction X1. The first overlapping area has a first dimension D1 in the first direction X1, and the first direction X1 extends from the geometric center of the first orthographic projection to the edge. It can be understood that the first orthographic projection of the first light-emitting device LD1 on the substrate SUB can be a rectangle, a square, a circle, etc., and the geometric center of the first orthographic projection is the geometric center of the aforementioned shape. The first direction X1 points from the geometric center of the first orthographic projection to the edge of the first orthographic projection.

[0031] In some embodiments, please refer to Figure 3 The width of the first light-emitting device LD1 is A, the size of the first dimension D1 is D1, the distance between the first light-shielding part LS1 and the first light-emitting device LD1 is H1, and the thickness of the first light-shielding part LS1 is H2, wherein D1≥A-(H1+H2).

[0032] This configuration allows the first light-shielding part LS1 to effectively block the light from the first light-emitting device LD1 at a viewing angle greater than 45° in the first direction X1, thereby limiting the viewing angle of the privacy pixel 20 in the first direction X1 to within 45°. This ensures that the display panel 100 has a good privacy protection effect in the first direction X1 when in privacy mode. Experiments conducted by the inventors have shown that by controlling D1≥A-(H1+H2), the light emission of the privacy pixel 20 at a 45° viewing angle in the first direction X1 can be controlled to be between 0.1% and 10% of the light emission at the vertical viewing angle (i.e., the frontal viewing angle). Therefore, when the display panel 100 is in privacy mode, the user will not be able to effectively view the display screen of the display panel 100 at a viewing angle greater than 45° in the first direction X1.

[0033] As an optional implementation, H1 can be set in the range of 20μm to 80μm; H2 can be set in the range of 1μm to 2μm; and D1 can be set in the range of 1μm to 10μm.

[0034] In some examples, please refer to Figure 4 The first orthographic projection and the second orthographic projection have a second overlapping area in the second direction X2. The second overlapping area has a second size D2 in the second direction X2, and the second size D2 is smaller than the first size D1. The second direction X2 extends from the geometric center of the first orthographic projection to the edge.

[0035] In other examples, please refer to Figure 5 and Figure 6 The first orthographic projection and the second orthographic projection do not overlap in the second direction X2.

[0036] For the display panel 100 provided in this application embodiment, since the overlap width (i.e., the first dimension D1) of the first orthographic projection and the second orthographic projection in the first direction X1 is greater than their overlap width in the second direction X2, the privacy pixel 20 has a better privacy protection effect in the first direction X1 than in the second direction X2. In other words, the privacy pixel 20 can be used to achieve directional privacy protection in at least one direction including the first direction X1, while not providing privacy protection in at least one direction including the second direction X2. This allows the display panel 100 to adapt to usage scenarios that only require privacy protection in a specific direction, thereby improving the user experience.

[0037] In specific application scenarios, the display panel 100 can be used, for example, with an office laptop, so that only one side of the view is protected from peeping, while the user on the other side can view the content displayed on the office laptop normally.

[0038] In some embodiments, please refer to Figure 5 In the second direction X2, the first edge E1 of the first orthographic projection and the second edge E2 of the second orthographic projection near the geometric center of the first orthographic projection coincide.

[0039] This configuration ensures that the edge of the first light-shielding part LS1 is flush with the edge of the first light-emitting device LD1 in the second direction X2. The light-shielding area of ​​the first light-shielding part LS1 is relatively small, which increases the viewing angle of the privacy pixel 20 in the second direction X2 and improves the viewing effect of the user from the side view in the second direction X2.

[0040] In some embodiments, please refer to Figure 6 The first edge E1 of the first orthographic projection on the second direction X2 is located between the second edge E2 of the second orthographic projection on the second direction X2, which is close to the geometric center of the first orthographic projection, and the geometric center.

[0041] This configuration allows the first light-shielding part LS1 to transmit light from a wider side angle in the second direction X2, thereby effectively expanding the viewing angle of the privacy pixel 20 in the second direction X2 and improving the user's visual experience in the second direction X2 when the display panel 100 is in privacy mode.

[0042] It is understandable that, since the orthographic projection of the first opening K1 of the first light-shielding part LS1 onto the substrate SUB is within the range of the orthographic projection of the second opening K2 of the second light-shielding part LS2 onto the substrate SUB, the first light-shielding part LS1 has a more significant effect on limiting light from the side viewing angle. In this embodiment, by adjusting the position of the second edge E2, the viewing angle of the privacy pixel 20 in the second direction X2 can be quickly and effectively controlled to improve the user's visual experience when the display panel 100 is in privacy mode. As an example, by adjusting the position of the second edge E2, light from the privacy pixel 20 within a 60° viewing angle in the second direction X2 can be effectively emitted, thereby controlling the viewing angle of the privacy pixel 20 in the second direction X2 to 60°.

[0043] In some examples, the distance D4 between the second edge E2 and the first edge E1 is smaller than the first dimension D1. This setting allows the privacy pixel 20 to effectively limit the light from a wide viewing angle in the second direction X2, thus ensuring that the display panel 100 still has a certain degree of privacy restriction in the second direction X2 when in privacy mode.

[0044] In some embodiments, a pixel unit PU includes two red privacy pixels R2, two green privacy pixels G2, and two blue privacy pixels B2. One red privacy pixel R2, one green privacy pixel G2, and one blue privacy pixel B2 constitute a first privacy pixel group, and the other red privacy pixel R2, the other green privacy pixel G2, and the other blue privacy pixel B2 constitute a second privacy pixel group. The privacy pixels 20 in the first privacy pixel group are used to achieve privacy in at least a first direction X1; the privacy pixels 20 in the second privacy pixel group are used to achieve privacy in at least a second direction X2. Thus, by switching between the activation of the first and second privacy pixel groups, targeted privacy in different directions can be achieved, thereby improving user flexibility.

[0045] In some embodiments, please continue reading Figures 4 to 6 The first direction X1 and the second direction X2 are opposite to each other.

[0046] In this embodiment, by setting the first direction X1 and the second direction X2, which have different light-blocking effects, to opposing viewing angles, the actual usage scenarios of the display screen being viewed from the left, right, up, and down can be matched, thereby enhancing the practicality of the directional anti-peeping function.

[0047] It is worth noting that in this embodiment, the first direction X1 and the second direction X2 are opposite to each other. However, in other embodiments, the first direction X1 and the second direction X2 may intersect each other.

[0048] It is understandable that for the red privacy pixel R2, green privacy pixel G2, and blue privacy pixel B2 in the same pixel unit PU, the relative positional relationship between their first light-emitting device LD1 and first light-shielding part LS1 is the same, thereby improving the display effect of the display panel 100 in privacy mode.

[0049] In some embodiments, such as Figure 7 As shown, the first orthographic projection and the second orthographic projection have a third overlapping area in the third direction X3, and the third overlapping area has a third size D3 in the third direction X3 that is equal to the first size D1; in the fourth direction X4, the third edge E3 of the first orthographic projection and the fourth edge E4 of the second orthographic projection near the geometric center of the first orthographic projection coincide; the fourth direction X4 and the third direction X3 extend from the geometric center of the first orthographic projection to the edge, respectively.

[0050] In this case, the privacy pixel 20 has a better privacy protection effect in the first direction X1 and the third direction X3 than in the second direction X2 and the fourth direction X4. Therefore, the privacy pixel 20 can be used to achieve directional privacy protection in multiple directions including the first direction X1 and the third direction X3, while not providing privacy protection in multiple directions including the second direction X2 and the fourth direction X4. This allows the display panel 100 to adapt to the usage scenario that only requires privacy protection in specific multiple directions, thereby improving the user experience.

[0051] In some examples, the third direction X3 and the first direction X1 are opposite to each other, and the fourth direction X4 and the second direction X2 are opposite to each other.

[0052] This setting ensures that the privacy pixel 20 has a privacy function in two opposing viewing angles, while it does not have a privacy function in the other two opposing viewing angles. This can match the real-world usage scenarios of the display screen where privacy is required for the left and right side views but not for the top and bottom side views, or vice versa, thereby enhancing the practicality of the directional privacy function.

[0053] In some examples, the first direction X1 and the second direction X2 are perpendicular to each other.

[0054] In other embodiments, the first and second orthographic projections have a third overlapping area in the third direction X3, and the third overlapping area has a third size D3 in the third direction X3 that is equal to the first size D1; the first and second orthographic projections have a fourth overlapping area in the fourth direction X4, and the fourth overlapping area has a size equal to the first size D1 in the fourth direction X4; the fourth direction X4 and the third direction X3 extend from the geometric center of the first orthographic projection to the edge, and the third direction X3 and the first direction X1 are opposite to each other, and the fourth direction X4 and the second direction X2 are opposite to each other. In this case, multi-sided privacy protection can be achieved for the display panel 100 in privacy mode in directions other than the second direction X2.

[0055] In some other embodiments, in the third direction X3, the fifth edge of the first orthographic projection and the sixth edge of the second orthographic projection near the geometric center of the first orthographic projection coincide; in the fourth direction X4, the third edge E3 of the first orthographic projection and the fourth edge E4 of the second orthographic projection near the geometric center of the first orthographic projection coincide; the fourth direction X4 and the third direction X3 extend from the geometric center of the first orthographic projection towards the edge, and the third direction X3 and the first direction X1 are opposite to each other, and the fourth direction X4 and the second direction X2 are opposite to each other. In this case, the display panel 100 can achieve privacy protection on only one side of the first direction X1 in privacy mode.

[0056] In some embodiments, such as Figure 8 As shown, the first orthographic projection is circular and includes a first arc-shaped edge AE1 and a second arc-shaped edge AE2 that are opposite to each other and connected end to end. The third orthographic projection of the first opening K1 of the first light-shielding part LS1 on the substrate SUB includes a third arc-shaped edge AE3 and a fourth arc-shaped edge AE4 that are opposite to each other and connected end to end. The third arc-shaped edge AE3 coincides with the first arc-shaped edge AE1, and the distance between the fourth arc-shaped edge AE4 and the second arc-shaped edge AE2 gradually decreases from the midpoint of the fourth arc-shaped edge AE4 towards both ends.

[0057] This configuration results in a crescent-shaped overlap between the first orthographic projection of the first light-emitting device LD1 onto the substrate SUB and the second orthographic projection of the first light-shielding portion LS1 onto the substrate SUB. The width (i.e., the first dimension D1) of this overlap region is greatest at the midpoint of the fourth arcuate edge AE4 in the first direction X1, and gradually decreases towards the two apexes of the crescent shape. Under these conditions, the privacy pixel 20 exhibits the best privacy protection effect in the first direction X1, thereby achieving directional privacy protection for the privacy pixel 20 in the first direction X1.

[0058] In some embodiments, such as Figure 9As shown, the shape of the first orthographic projection is circular; the shape of the third orthographic projection of the first opening K1 of the first light-shielding part LS1 on the substrate SUB is elliptical, and the geometric center of the third orthographic projection coincides with the geometric center of the first orthographic projection.

[0059] This configuration, with the geometric centers of the ellipse and the circle coinciding, results in a relatively large overlap between the first orthographic projection and the second orthographic projection of the first light-shielding part LS1 on the substrate SUB in two opposing directions, while having a relatively small overlap or no overlap in the other two opposing directions. This allows the privacy pixel 20 to provide privacy protection from two opposing viewing angles, while not providing privacy protection from the other two opposing viewing angles. This effectively matches the actual usage scenarios of the display screen and enhances the practicality of the directional privacy protection function. Furthermore, since the first opening K1 is a regular shape, this also facilitates the fabrication of the first opening K1 of the first light-shielding part LS1.

[0060] In some examples, the third orthographic projection and the first orthographic projection overlap at their opposite edges. This arrangement results in two overlapping regions: the first orthographic projection of the first light-emitting device LD1 on the substrate SUB and the second orthographic projection of the first light-shielding portion LS1 on the substrate SUB. Both overlapping regions are crescent-shaped. In this configuration, the privacy pixel 20 can achieve a good directional privacy protection effect.

[0061] Some embodiments of this application also provide a display device, such as... Figure 10 As shown, the display device 1000 includes the display panel 100 described in any of the above embodiments.
