Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of display, in particular to a display panel and a display device. BACKGROUND

[0002] Users have privacy needs when using display products in public places. Although the anti-peeping film meets the privacy needs of users, after the anti-peeping film is pasted, only the user directly opposite the screen can see the content on the screen, which limits the use environment of the display product after the film is pasted. In recent years, active anti-peeping technology capable of realizing flexible switching between anti-peeping and non-anti-peeping has developed to a certain extent. In the active anti-peeping technology, the pixels are divided into shared pixels and anti-peeping pixels. The anti-peeping pixels can be turned on only in anti-peeping mode, and the anti-peeping pixels and the shared pixels can be turned on simultaneously in shared mode. The current active anti-peeping scheme has the problem of low large-angle brightness in shared mode. SUMMARY

[0003] Embodiments of the present application provide a display panel and a display device to solve the problem of low large-angle brightness in shared mode in the prior art.

[0004] In a first aspect, embodiments of the present application provide a display panel, which comprises: a substrate; a light shielding layer, the light shielding layer comprising a light shielding structure, a first opening and a second opening; in a direction perpendicular to a plane where the substrate is located, the first opening overlaps with a shared sub-pixel, and the second opening overlaps with an anti-peeping sub-pixel; wherein the shared sub-pixel comprises a color resistance unit, the color resistance unit being located in the first opening; the first opening comprises a first region and a second region, the second region being located between the first region and the light shielding structure; the thickness of the color resistance unit in the second region is less than the thickness of the color resistance unit in the first region.

[0005] In a second aspect, based on the same inventive concept, embodiments of the present application provide a display device comprising the display panel provided by any of the embodiments of the present application.

[0006] The display panel and display device provided in this invention have the following beneficial effects: The display panel includes a shared sub-pixel and a privacy sub-pixel. A first opening in the light-shielding layer overlaps with the shared sub-pixel, and a second opening overlaps with the privacy sub-pixel. The first area of ​​the first opening corresponds to the central light-emitting area of ​​the shared sub-pixel, and the second area of ​​the first opening corresponds to the peripheral light-emitting area of ​​the shared sub-pixel. Some of the light emitted by the shared sub-pixel towards a wide viewing angle needs to be emitted through the second area. The thickness of the color resist unit in the second area is set to be less than its thickness in the first area. By thinning the thickness of the color resist unit in the second area, the transmittance of the second area is made greater than that of the first area, which can increase the amount of light emitted by the shared sub-pixel through the second area, thereby increasing the light emission of the shared sub-pixel towards a wide viewing angle. In the sharing mode, both the shared sub-pixel and the privacy sub-pixel emit light. The light emission of the shared sub-pixel towards a positive viewing angle and the light emission of the privacy sub-pixel towards a positive viewing angle are superimposed. By increasing the amount of light emitted by the shared sub-pixel towards a wide viewing angle, the brightness of the shared sub-pixel at a wide viewing angle can be improved, thus improving the problem of low brightness at a wide viewing angle in the sharing mode.

Detailed Implementation

[0009] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0010] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” as used in the embodiments of this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0011] Various modifications and variations can be made to this invention without departing from its spirit or scope, as will be apparent to those skilled in the art. Therefore, this invention is intended to cover modifications and variations falling within the scope of the corresponding claims (the claimed technical solutions) and their equivalents.

[0012] It should be noted that the implementation methods provided in the embodiments of the present invention can be combined with each other without contradiction.

[0013] The relevant technology incorporates shared subpixels and privacy subpixels. In privacy mode, the privacy subpixel emits light, while in shared mode, both the shared and privacy subpixels emit light. Since the light emitted by the privacy subpixel is primarily directed towards the frontal viewing angle, while the light emitted by the shared subpixel is directed towards both the frontal and wide viewing angles, the combined light from the privacy and shared subpixels in shared mode results in a relatively smaller amount of light directed towards the wide viewing angle compared to the frontal viewing angle. This leads to lower brightness in the shared mode at wide viewing angles.

[0014] To address the problems existing in related technologies, embodiments of the present invention provide a display panel that improves the structure of shared sub-pixels. By setting different film thicknesses for the color resist units along the light emission path of the shared sub-pixels, the obstruction of light emission from the shared sub-pixels to a wider viewing angle by the color resist units is reduced, increasing the amount of light emitted from the shared sub-pixels to a wider viewing angle. This improves the problem of low brightness in the shared state at a wider viewing angle. The above is the main technical concept of the present invention. Specific embodiments are described below.

[0015] Figure 1 This is a schematic diagram of a display panel provided in an embodiment of the present invention, such as... Figure 1 As shown, the display panel includes a substrate 00 and a light-shielding layer 10 located on the substrate 00. The light-shielding layer 10 includes a light-shielding structure 11, a first opening K1, and a second opening K2. The light-shielding structure 11 functions to block light. The first opening K1 and the second opening K2 are respectively surrounded by the light-shielding structure 11, or in other words, the light-shielding structure 11 is located between adjacent openings on the light-shielding layer 10. Along the direction e perpendicular to the plane of the substrate 00, the first opening K1 overlaps with a shared sub-pixel sp1, and the second opening K2 overlaps with a privacy sub-pixel sp2. That is, the first opening K1 is on the light-emitting path of the shared sub-pixel sp1, and the second opening K2 is on the light-emitting path of the privacy sub-pixel sp2.

[0016] The shared sub-pixel sp1 and the privacy sub-pixel sp2 each include a light-emitting device 30, which may be, for example, an organic light-emitting device. Figure 1 The light-emitting device 30 is only shown in a simplified diagram. The light-emitting device 30 may include a stacked first electrode, a light-emitting layer, and a second electrode, where the first electrode is the anode and the second electrode is the cathode. Pixel circuitry is also provided in the display panel. Figure 1 (Not shown), the pixel circuit is electrically connected to the first electrode and is used to drive the light-emitting device 30 to emit light. The display panel includes a privacy mode and a sharing mode. In the privacy mode, the privacy sub-pixel sp2 emits light, and in the sharing mode, the shared sub-pixel sp1 and the privacy sub-pixel sp2 emit light together. The display panel includes at least three colors of pixels: red, green, and blue. These three colors of pixels work together as pixel units. For example, each color pixel includes a shared sub-pixel sp1 and a privacy sub-pixel sp2, meaning the display panel includes three colors of shared sub-pixels sp1 and three colors of privacy sub-pixels sp2.

[0017] The shared sub-pixel sp1 includes a color resist unit 20 located within a first opening K1. The first opening K1 includes a first region Z1 and a second region Z2, with the second region Z2 located between the first region Z1 and the light-shielding structure 11. Typically, the second region Z2 surrounds the first region Z1. The thickness of the color resist unit 20 within the second region Z2 is less than its thickness within the first region Z1. Regarding the thickness difference of the color resist unit 20 within the first region Z1 and the second region Z2 in the shared sub-pixel sp1, in some embodiments, the shared sub-pixel sp1 of one color in the display panel may have the following characteristics: Figure 1 The design; in other embodiments, the shared sub-pixels sp1 of the two colors may each have such... Figure 1 The design could also be that three colors share a sub-pixel sp1, each having the following characteristics: Figure 1 The design.

[0018] The display panel provided in this embodiment of the invention includes a shared sub-pixel sp1 and a privacy sub-pixel sp2. A first opening K1 in the light-shielding layer 10 overlaps with the shared sub-pixel sp1, and a second opening K2 overlaps with the privacy sub-pixel sp2. The first opening K2 corresponding to the shared sub-pixel sp1 includes a first region Z1 and a second region Z2, with the second region Z2 located between the first region Z1 and the light-shielding structure 11. Based on the relative positions of the first region Z1 and the second region Z2 with the light-shielding structure 11, it can be known that the first region Z1 corresponds to the central light-emitting area of ​​the shared sub-pixel sp1, and the second region Z2 corresponds to the peripheral light-emitting area of ​​the shared sub-pixel sp1. Figure 1 As shown by the schematic arrows, some of the light emitted by the shared sub-pixel sp1 towards the wide viewing angle needs to pass through the second region Z2. The thickness of the color resist unit 20 in the second region Z2 is set to be less than its thickness in the first region Z1. By thinning the color resist unit 20 in the second region Z2, the transmittance of the second region Z2 is made greater than that of the first region Z1, which increases the amount of light emitted by the shared sub-pixel sp1 through the second region Z2, thereby increasing the amount of light emitted by the shared sub-pixel sp1 towards the wide viewing angle. In the sharing mode, both the shared sub-pixel sp1 and the privacy sub-pixel sp2 emit light. The light emitted by the shared sub-pixel sp1 towards the forward viewing angle and the light emitted by the privacy sub-pixel sp2 towards the forward viewing angle are superimposed. By increasing the amount of light emitted by the shared sub-pixel sp1 towards the wide viewing angle, the brightness at a wide viewing angle in the sharing mode can be improved, thus addressing the problem of low brightness at a wide viewing angle in the shared state.

[0019] In this embodiment of the invention, the amount of light emitted through the second region Z2 in the shared sub-pixel sp1 is increased by reducing the thickness of the color resist unit 20 in the second region Z2. One approach to reducing the thickness of the color resist unit 20 in the second region Z2 is to have a color resist unit 20 in the second region Z2, but with a thickness less than that of the color resist unit 20 in the first region Z1; another approach is to reduce the thickness of the color resist unit 20 in the second region Z2 to zero, in other words, to not have a color resist unit 20 in the second region Z2.

[0020] For example, such as Figure 1 As shown, the color resist unit 20 is located in the first region Z1, and the area between the color resist unit 20 and the light-shielding structure 11 is the second region Z2. That is, the color resist unit 20 included in the shared sub-pixel sp1 does not contact the light-shielding structure 11. In this embodiment, the thickness of the color resist unit 20 in the second region Z2 is reduced to 0, making the second region Z2 of the first opening K1 a high-transmittance region. This increases the amount of light emitted from the shared sub-pixel sp1 through the second region Z2, thereby increasing the amount of light emitted from the shared sub-pixel sp1 to a wider viewing angle. This improves the brightness at a wider viewing angle in the shared mode, addressing the problem of low brightness at a wider viewing angle in the shared state.

[0021] For example, Figure 2 This is another schematic diagram of a display panel provided in an embodiment of the present invention, such as... Figure 2 As shown, the color resist unit 20 includes a first portion 20-1 and a second portion 20-2. The first portion 20-1 is located in the first region Z1, and the second portion 20-2 is located in the second region Z2. The thickness of the second portion 20-2 is less than the thickness of the first portion 20-1. In this embodiment, the thickness of the color resist unit 20 in the second region Z2 is reduced, while a certain thickness of the color resist unit 20 is retained within the second region Z2. This makes the transmittance of the second region Z2 greater than that of the first region Z1, increasing the amount of light emitted from the shared sub-pixel sp1 via the second region Z2, thereby increasing the amount of light emitted from the shared sub-pixel sp1 to a wider viewing angle. This improves the brightness at a wider viewing angle in the shared mode, addressing the problem of low brightness at a wider viewing angle in the shared state. Furthermore, in this embodiment, retaining a thinner color resist unit 20 within the second region Z2 allows this area to still have a filtering function, reducing the reflectivity of the display panel. Taking the color resist unit 20 in the second zone Z2 as a green color resist as an example, ambient light enters the display panel and is reflected, while the red and blue light that shines on the second zone Z2 will be blocked by the green color resist and cannot be emitted, thus reducing the amount of reflected ambient light emitted, reducing the reflectivity of the display panel, and improving the display effect.

[0022] Optional, such as Figure 2As shown, the thickness of the first part 20-1 is d1, and the thickness of the second part 20-2 is d2, where 0 < d2 / d1 ≤ 1 / 2. In this embodiment, the transmittance of the second region Z2 is increased by thinning the color resistance unit 20 in the second region Z2, and a certain thickness of the color resistance unit 20 is retained in the second region Z2. When designing, the thinner the thickness d2 of the second part 20-2 is, the better. For example, if the color resistance unit 20 is a green color resistance, the thinner the thickness d2 of the second part 20-2 is, the greater the transmittance of green light is, and even if the thickness d2 of the second part 20-2 is very small, red light and blue light cannot pass through. Therefore, as long as a certain thickness of the color resistance unit 20 is retained in the second region Z2, the effects of reducing reflection and increasing light extraction efficiency can be achieved. Considering the difficulty of the manufacturing process and the comprehensive consideration of the transmittance, 0 < d2 / d1 ≤ 1 / 2 is set.

[0023] In addition, as Figure 1 and Figure 2 shown, the anti-peeping sub-pixel sp2 includes a color resistance unit 20. At least part of the color resistance unit 20 of the anti-peeping sub-pixel sp2 is located in the second opening K2, and the color resistance unit 20 of the anti-peeping sub-pixel sp2 contacts the light shielding structure 11. By setting the color resistance unit 20, the reflectivity of the display panel can be reduced.

[0024] Combined with Figure 1 and Figure 2 viewed, the display panel includes an auxiliary dimming layer 60, and the auxiliary dimming layer 60 is located on the side of the light shielding layer 10 away from the substrate 00; the auxiliary dimming layer 60 includes a third opening K3 and a fourth opening K4. Along the direction e perpendicular to the plane where the substrate 00 is located, the third opening K3 overlaps with the shared sub-pixel sp1, and the fourth opening K4 overlaps with the anti-peeping sub-pixel sp2. In the embodiment of the present invention, the auxiliary dimming layer 60 and the light shielding layer 10 are used as a double-layer light shielding structure to cooperate to achieve the anti-peeping effect of the anti-peeping sub-pixel sp2.

[0025] Figure 3 is a schematic diagram of the design principle of the double-layer light shielding structure in the embodiment of the present invention. As Figure 3 shown, in order to meet the light-emitting requirements of the anti-peeping sub-pixel sp2 in the positive viewing direction, a first light shielding portion 010 is initially provided. The light S1 emitted from the edge position of the anti-peeping sub-pixel sp2 is emitted from the edge of the first light shielding portion 010, and the light S1 refracted and then emitted from the display panel forms a 45° angle with the front viewing direction. That is to say, the light with an angle greater than 45° can be blocked by the first light shielding portion 010. And the light with an angle less than 45° cannot be blocked by the first light shielding portion 010. Considering blocking the light with a smaller light-emitting angle, the position of the light shielding portion needs to be raised, and thus a second light shielding portion 020 is provided. As Figure 3As illustrated, light ray S2 is a critical ray that can be emitted from the edge of the second light-shielding part 020. Compared to light ray S1, light ray S2 has a smaller angle with the viewing direction, so the second light-shielding part 020 can block emitted light rays with an angle of less than 45°. If only the second light-shielding part 020 is provided, the width of the second light-shielding part 020 needs to be increased to block the large-angle light ray S3 emitted towards the adjacent sub-pixel. After refraction, the light ray S3 emitted from the display panel forms a 90° angle with the viewing direction. At the same time, since the spacing between the shared sub-pixel sp1 and the privacy sub-pixel sp2 in the panel is limited, increasing the width of the second light-shielding part 020 will also affect the light emission of the adjacent shared sub-pixel sp1 to a wide viewing angle. Considering that the first light-shielding part 010 is used to block light ray S3, the width of the second light-shielding part 020 located above the first light-shielding part 010 does not need to be too large. A first light-shielding part 010 and a second light-shielding part 020 are arranged in the display panel. The first light-shielding part 010 blocks the large-angle light emitted towards the adjacent sub-pixel, and the second light-shielding part 020 blocks the relatively large-angle light emitted directly upward from the privacy sub-pixel. The first light-shielding part 010 and the second light-shielding part 020 work together. In this way, the two light-shielding parts do not need to be too wide to meet the requirement that the privacy sub-pixel sp2 mainly emits light in the direction of direct viewing.

[0026] This invention Figure 1 and Figure 2 In this embodiment, the light-shielding layer 10 serves as the first light-shielding part, and the auxiliary dimming layer 60 serves as the second light-shielding part. The light-shielding layer 10 and the auxiliary dimming layer 60 cooperate with each other to meet the requirement that the privacy pixel sp2 emits light in the forward-looking direction.

[0027] In some embodiments, the thickness of the color resist unit 20 in the shared sub-pixel sp1 is set differently in the first region Z1 and the second region Z2, reducing the thickness of the color resist unit 20 in the second region Z2 to 0. Different settings can be made for the shared sub-pixel structures of different colors.

[0028] For example, Figure 4 This is a schematic diagram of another display panel provided in an embodiment of the present invention. Figure 4As shown, the display panel includes a first pixel P1 and a second pixel P2 with different emission colors; the first pixel P1 includes a shared sub-pixel sp1 and a privacy sub-pixel sp2 with the same emission color, and the second pixel P2 includes a shared sub-pixel sp1 and a privacy sub-pixel sp2 with the same emission color; the color resist unit 20 includes a first color resist 21 and a second color resist 22; the shared sub-pixel sp1 of the first pixel P1 includes the first color resist 21, and the shared sub-pixel sp1 of the second pixel P2 includes the second color resist 22. That is, in the first pixel P1, the first color resist 21 is located in the first region Z1, and the area between the first color resist 21 and the light-shielding structure 11 is the second region Z2; in the second pixel P2, the second color resist 22 is located in the first region Z1, and the area between the second color resist 22 and the light-shielding structure 11 is the second region Z2. Wherein, along the first direction a, the distance between the first color resist 21 and the light-shielding structure 11 is L1, and the distance between the second color resist 22 and the light-shielding structure 11 is L2; ​​L1>L2; the first direction a is parallel to the plane where the substrate 00 is located.

[0029] In this embodiment, the thickness of the first color resist 21 of the shared sub-pixel sp1 in the first pixel P1 can be reduced to 0 in the second region Z2, and the thickness of the second color resist 22 of the shared sub-pixel sp1 in the second pixel P2 can also be reduced to 0 in the second region Z2. This increases the light emission of the shared sub-pixel sp1 in the first pixel P1 to a wider viewing angle, and also increases the light emission of the shared sub-pixel sp1 in the second pixel P2 to a wider viewing angle, thereby improving the brightness at a wider viewing angle in the shared mode. Moreover, considering that the proportion of light emitted by the red, green, and blue color pixels is different when they emit white light together, the distance between the first color resist 21 and the light-shielding structure 11 is set to be greater than the distance between the second color resist 22 and the light-shielding structure 11, so that the increase in the amount of light emitted by different color pixels to a wider viewing angle is different. By setting the amount of light emitted by the shared sub-pixel sp1 in the first pixel P1 to a wider viewing angle to be greater, it is possible to avoid character bias at a wider viewing angle while improving the brightness at a wider viewing angle.

[0030] For example, the first pixel P1 emits green light, and the second pixel P2 emits either red or blue light. When displaying white light, the ratio of green, blue, and red light is 7:1:2, with green light having a relatively larger proportion, while the proportions of red and blue light are close. The maximum distance between the color resist unit and the light-blocking structure 11 in the shared sub-pixel sp1 that emits green light can be set to ensure the required amount of green light when displaying white light at a wide viewing angle. Alternatively, the distance between the color resist unit and the light-blocking structure 11 in the shared sub-pixel sp1 that emits red light can be set to be equal to the distance between the color resist unit and the light-blocking structure 11 in the shared sub-pixel sp1 that emits blue light.

[0031] For example, Figure 5This is a schematic diagram of another display panel provided in an embodiment of the present invention. Figure 5 As shown, in the shared sub-pixel sp1, the color resist unit 20 is located in the first region Z1, and the area between the color resist unit 20 and the light-shielding structure 11 is the second region Z2. The shared sub-pixel sp1 and the privacy sub-pixel sp2 each include a light-emitting device 30. The light-emitting device 30 includes a stacked first electrode 31, a light-emitting layer 32, and a second electrode 33. The first electrode 31 is a reflective electrode, and the second electrode 33 is a semi-reflective and semi-transparent electrode. The first electrode 31 is a patterning electrode, and the second electrodes 33 of adjacent light-emitting devices 30 are interconnected to form a common electrode layer. The display panel also includes a low-transmittance structure 40, which is located between the film layer containing the light-emitting device 30 and the light-shielding layer 10. Along the direction e perpendicular to the plane of the substrate 00, the low-transmittance structure 40 and the second region Z2 at least partially overlap. The material of the low-transmittance structure 40 includes low-transmittance materials, such as metal oxides. In this embodiment of the invention, the color resist unit 20 of the shared sub-pixel sp1 is disposed in the first region Z1, and the thickness of the color resist unit 20 in the second region Z2 is 0, thereby increasing the transmittance of the second region Z2 and increasing the amount of light emitted from the shared sub-pixel sp1 through the second region Z2, thus increasing the amount of light emitted from the shared sub-pixel sp1 to a wide viewing angle and improving the problem of low brightness in the shared state at a wide viewing angle. Considering that although the second electrode 33 is a semi-reflective and semi-transparent electrode, its manufacturing material includes metal materials, the common electrode layer formed by the second electrode 33 also has a certain reflectivity to ambient light. When the thickness of the color resist unit 20 in the second region Z2 is 0, the ambient light reflected by the common electrode layer will be emitted from the second region Z2. Based on this, a low-transmittance structure 40 is further disposed between the light-emitting device 30 and the light-shielding layer 10. The low-transmittance structure 40 is used to block the common electrode layer overlapping with the second region Z2, avoiding the reflection of ambient light by the common electrode layer, thereby reducing the reflectivity of the display panel and improving the display effect.

[0032] For example, such as Figure 5As shown, the display panel includes an encapsulation layer 50, which is located between multiple light-emitting devices 30 and a light-shielding layer 10. The encapsulation layer 50 includes a first inorganic layer 51 and an organic layer 52, with the first inorganic layer 51 located on the side of the organic layer 52 closest to the substrate 00. A low-transmittance structure 40 is located on the side of the first inorganic layer 51 closest to the light-emitting devices 30. The encapsulation layer 50 is used to protect the light-emitting devices 30 from water and oxygen, and is the film layer on top of the light-emitting devices 30 closest to them. The low-transmittance structure 40 is positioned on the side of the first inorganic layer 51 closest to the light-emitting devices 30, so that the low-transmittance structure 40 is in contact with the film layer containing the second electrode 33 of the light-emitting devices 30. The low-transmittance structure 40 blocks the common electrode layer overlapping with the second region Z2, preventing the common electrode layer from reflecting ambient light. Moreover, since the low-transmittance structure 40 is close to the light-emitting device 30 in the plane perpendicular to the substrate 00, the low-transmittance structure 40 will not affect the light emission of the light-emitting device 30, ensuring that the light emission of the shared sub-pixel sp1 to a wide viewing angle is not affected.

[0033] For example, Figure 6 This is a schematic diagram of another display panel provided in an embodiment of the present invention. Figure 6 As shown, the encapsulation layer 50 is located between multiple light-emitting devices 30 and the light-shielding layer 10; the encapsulation layer 50 includes a first inorganic layer 51 and an organic layer 52, with the first inorganic layer 51 located on the side of the organic layer 52 closer to the substrate 00; a low-transmittance structure 40 is located between the first inorganic layer 51 and the organic layer 52. In this embodiment, the low-transmittance structure 40 and the common electrode layer formed by the second electrode 33 are separated only by the first inorganic layer 51. The low-transmittance structure 40 can shield the common electrode layer overlapping with the second region Z2, preventing the common electrode layer from reflecting ambient light; moreover, since the low-transmittance structure 40 is relatively close to the light-emitting device 30 in the direction perpendicular to the plane of the substrate 00, the low-transmittance structure 40 will not affect the light emission of the light-emitting device 30, ensuring that the light emission of the shared sub-pixel sp1 to a wide viewing angle is not affected.

[0034] like Figure 5 or Figure 6 As shown, along the direction e perpendicular to the plane containing the substrate 00, the edge of the low-transmittance structure 40 overlaps with the light-shielding structure 11, and / or, the edge of the low-transmittance structure 40 is aligned with the edge of the color resist unit 20. By setting the edge of the low-transmittance structure 40 to overlap with the light-shielding structure 11, the common electrode layer overlapping with the second region Z2 can be completely blocked at a position far from the light-emitting device 30 of the shared sub-pixel sp1, preventing the common electrode layer from reflecting ambient light. Conversely, by setting the edge of the low-transmittance structure 40 to align with the edge of the color resist unit 20 at a position closer to the light-emitting device 30 of the shared sub-pixel sp1, the low-transmittance structure 40 can avoid affecting the light emitted by the light-emitting device 30 to a wide viewing angle.

[0035] For example, Figure 7This is a schematic diagram of another display panel provided in an embodiment of the present invention. Figure 7 As shown, the display panel includes a third pixel P3, which includes a shared sub-pixel sp1 and a privacy sub-pixel sp2 with the same emission color; the color resist unit 20 includes a third color resist 23; the shared sub-pixel sp1 of the third pixel P3 includes the third color resist 23. That is, in the third pixel P3, the first opening K1 includes a first region Z1, a second region Z2, and a third region Z3. The third color resist 23 is located in the first region Z1, and the area between the third color resist 23 and the light-shielding structure 11 is the second region Z2. The third region Z3 is located between the first region Z1 and the light-shielding structure 11. The second region Z2 and the third region Z3 are independent regions, wherein the area between the third color resist 23 and the light-shielding structure 11, excluding the third region Z3, is the second region Z2. The auxiliary color resist 24 is located in the third region Z3, and the color of the auxiliary color resist 24 is the same as the color of the third color resist 23. In this embodiment, the thickness of the color resist unit 20 in the second region Z2 is reduced to 0, making the thickness of the color resist unit 20 in the second region Z2 less than its thickness in the first region Z1. The auxiliary color resist 24 located in the third region Z3 has a certain light-blocking capability. The auxiliary color resist 24 is located between the first region Z1 and the light-blocking structure 11, and the auxiliary color resist 24 and the third color resist 23 do not contact each other. In this embodiment, no color resist unit is set in the second region Z2, which can increase the overall light output of the shared sub-pixel sp1 over a wide viewing angle. At the same time, the auxiliary color resist 24 in the third region Z3 blocks the light emitted by the light-emitting device 30 at certain angles, realizing the adjustment of light over a wide viewing angle and improving the problem of color shift over a wide viewing angle.

[0036] For example, for red, green, and blue pixels, one of the color pixels can be set to have... Figure 7 The auxiliary color filter 24 is shown in the diagram. It is used to adjust the proportion of light at certain angles in a wide viewing angle.

[0037] In some embodiments, the thickness of the color resist unit 20 in the shared sub-pixel sp1 is set differently in the first region Z1 and the second region Z2. The color resist unit 20 is disposed in the second region Z2, but its thickness is less than that of the color resist unit 20 in the first region Z1. The different settings can be made for the shared sub-pixel structure of different colors.

[0038] For example, Figure 8 This is a schematic diagram of another display panel provided in an embodiment of the present invention. Figure 8As shown, the display panel includes a first pixel P1 and a second pixel P2 with different emission colors; the first pixel P1 includes a shared sub-pixel sp1 and a privacy sub-pixel sp2 with the same emission color, and the second pixel P2 includes a shared sub-pixel sp1 and a privacy sub-pixel sp2 with the same emission color; the color resist unit 20 includes a first color resist 21 and a second color resist 22; the shared sub-pixel sp1 of the first pixel P1 includes the first color resist 21, and the shared sub-pixel sp1 of the second pixel P2 includes the second color resist 22.

[0039] The first color resist 21 includes a first portion 20-1 and a second portion 20-2, wherein the thickness of the second portion 20-2 is less than the thickness of the first portion 20-1; the second color resist 22 includes a first portion 20-1 and a second portion 20-2, wherein the thickness of the second portion 20-2 is less than the thickness of the first portion 20-1. The thickness of the second portion 20-2 in the first color resist 21 is d21, and the thickness of the second portion 20-2 in the second color resist 22 is d22. <d21<d22。

[0040] In this embodiment, the shared sub-pixel sp1 in both the first pixel P1 and the second pixel P2 retains a certain thickness of color group unit 20 in the second region Z2. This increases the light emission of the shared sub-pixel sp1 in both the first and second pixels P1 towards a wider viewing angle, thereby improving the brightness at a wider viewing angle in the shared mode. Furthermore, considering the different light proportions of red, green, and blue pixels when emitting white light, the thickness of the second portion 20-2 in the first color resist 21 of the first pixel P1 is set to be relatively smaller, resulting in different degrees of increase in the amount of light emitted by different color pixels towards a wider viewing angle. By setting the shared sub-pixel sp1 of the first pixel P1 to increase the amount of light emitted towards a wider viewing angle, it is possible to improve the brightness at a wider viewing angle while avoiding character shift at a wider viewing angle.

[0041] For example, the first pixel P1 emits green light, and the second pixel P2 emits either red or blue light. When displaying white light, the ratio of green, blue, and red light is 7:1:2, with green light having a relatively larger proportion, while the proportions of red and blue light are close. It is possible to set the thickness of the second portion 20-2 within the second region Z2 of the shared sub-pixels emitting green light to be the smallest. Alternatively, the thickness of the second portion 20-2 of the color resist unit in the shared sub-pixel sp1 emitting red light can be set to be equal to the thickness of the second portion 20-2 of the color resist unit in the shared sub-pixel sp1 emitting blue light.

[0042] For example, Figure 9 This is a schematic diagram of another display panel provided in an embodiment of the present invention. Figure 9As shown, the display panel includes a first pixel P1 and a second pixel P2 with different emission colors; the first pixel P1 includes a shared sub-pixel sp1 and a privacy sub-pixel sp2 with the same emission color, and the second pixel P2 includes a shared sub-pixel sp1 and a privacy sub-pixel sp2 with the same emission color; the color resist unit 20 includes a first color resist 21 and a second color resist 22; the shared sub-pixel sp1 of the first pixel P1 includes the first color resist 21, and the shared sub-pixel sp1 of the second pixel P2 includes the second color resist 22.

[0043] The first color resist 21 is located in the first region Z1, and the region between the first color resist 21 and the light-shielding structure 11 is the second region Z2; the second color resist 22 includes a first part 20-1 and a second part 20-2, and the thickness of the second part 20-2 is less than the thickness of the first part 20-1.

[0044] In this embodiment, the thickness of the first color resist 21 of the shared sub-pixel sp1 in the first pixel P1 is reduced to 0 in the second region Z2, making the second region Z2 a high-transmittance area and increasing the light emission of the shared sub-pixel sp1 in the first pixel P1 to a wider viewing angle. The thickness of the second color resist 22 of the shared sub-pixel sp1 in the second pixel P2 is reduced in the second region Z2 while retaining a certain thickness, thereby increasing the light emission of the shared sub-pixel sp1 in the second pixel P2 to a wider viewing angle. By adopting a differentiated design for the shared sub-pixel sp1 of the first pixel P1 and the shared sub-pixel sp1 of the second pixel P2, the light emission of the shared sub-pixel sp1 in the first pixel P1 and the shared sub-pixel sp1 in the second pixel P2 to a wider viewing angle can be increased, improving the brightness at a wider viewing angle in the shared mode.

[0045] For example, Figure 9 In this embodiment, the first pixel P1 emits green light, and the second pixel P2 emits either red or blue light. The second region Z2 corresponding to the shared sub-pixel sp1 in the first pixel P1 is a high-transmittance region. Compared to the second pixel P2, the shared sub-pixel sp1 in the first pixel P1 emits more light towards a wider viewing angle. Considering the different proportions of the three colors of light when emitting white light, setting the first pixel P1 to emit green light ensures the required amount of green light when displaying white light at a wide viewing angle.

[0046] For example, Figure 10 This is a schematic diagram of another display panel provided in an embodiment of the present invention. Figure 10As shown, the second division 20-2 includes a first sub-division 1a and a second sub-division 1b; the first sub-division 1a connects the first division 20-1 and the second sub-division 1b. The thickness of the first sub-division 1a is greater than the thickness of the second sub-division 1b, and the thickness of the first sub-division 1a is less than the thickness of the first division 20-1. In this embodiment, the second division 20-2 has two sub-divisions with different thicknesses. Since the thickness of the first sub-division 1a is greater than the thickness of the second sub-division 1b, the transmittance of the first sub-division 1a is less than the transmittance of the second sub-division 1b. The thickness of both the first sub-division 1a and the second sub-division 1b is less than the thickness of the first division 20-1, increasing the transmittance of the second region Z2. This increases the overall light output of the shared sub-pixel sp1 over a wide viewing angle, improves the brightness over a wide viewing angle, and addresses the problem of low brightness over a wide viewing angle in the shared state. Simultaneously, the two sub-divisions with different thicknesses allow for the distribution of light emitted from the light-emitting device 30 over a wide viewing angle, resulting in a relatively larger increase in light output at certain angles and a relatively smaller increase at others, thereby helping to improve the problem of color shift over a wide viewing angle.

[0047] Optional, such as Figure 10 As shown, the thickness of the first sub-part 1a gradually increases from the direction of the light-shielding structure 11 toward the first region Z1.

[0048] For example, Figure 11 This is a schematic diagram of another display panel provided in an embodiment of the present invention. Figure 11 As shown, the thickness of the first sub-part 1a gradually increases from the direction of the light-shielding structure 11 toward the first region Z1; the display panel includes a refractive material layer 70; the refractive material layer 70 is located on the side of the color resist unit 20 away from the substrate 00; the refractive index of the refractive material layer 70 is less than the refractive index of the color resist unit 20. In this embodiment, the color resist unit 20 and the refractive material layer 70 are stacked at the shared sub-pixel sp1 position to form a microlens-like structure. The light emitted by the light-emitting device 30 is refracted through the cross-section where the color resist unit 20 and the refractive material layer 70 are in contact, causing the light propagation direction to deflect toward the viewing direction, thereby improving the light extraction efficiency of the light-emitting device 30.

[0049] Figure 12 This is a graph showing the brightness curve of a subpixel from a viewing angle. Figure 12 The diagram illustrates the brightness curves of the privacy sub-pixel sp2, the shared sub-pixel sp1, and the shared state pixel sp′ when both privacy sub-pixels sp2 and sp1 are lit, under different viewing angles. The horizontal axis represents the viewing angle, and the vertical axis represents the brightness. Figure 12As can be seen, the brightness of all three sub-pixels is 100% only at a direct viewing angle. At slightly off-center angles, such as ±10°, the brightness of the privacy sub-pixel sp2 and the shared sub-pixel sp1 differs considerably. In other words, the brightness of the privacy sub-pixel sp2 and the shared sub-pixel sp1 is the same only when viewed from a near-zero viewing angle; at slightly off-center angles (such as ±10°), their brightness differs. In application, the privacy sub-pixel sp2 emits light in privacy mode, while in sharing mode, both the shared sub-pixel sp1 and the privacy sub-pixel sp2 emit light. Due to the brightness difference between the privacy sub-pixel sp2 and the shared sub-pixel sp1, screen flickering occurs when switching between the two modes.

[0050] To address the screen flickering issue during mode switching, this embodiment of the invention further designs the overlap relationship between the first region Z1 above the shared sub-pixel sp1 and the light-emitting device 30.

[0051] For example, Figure 13 This is a schematic diagram of another display panel provided in an embodiment of the present invention. Figure 13 As shown, the shared sub-pixel sp1 and the privacy sub-pixel sp2 each include a light-emitting device 30; along the plane direction e perpendicular to the substrate 00, the first region Z1 covers the light-emitting device 30 of the shared sub-pixel sp1. The orthographic projection of the first region Z1 onto the substrate 00 coincides with the orthographic projection of the light-emitting device 30 of the shared sub-pixel sp1 onto the substrate 00, or the projected area of ​​the first region Z1 onto the substrate 00 may be larger than the projected area of ​​the light-emitting device 30 of the shared sub-pixel sp1 onto the substrate 00. This embodiment ensures that the first region Z1 is located directly above the light-emitting device 30 in the shared sub-pixel sp1, and that the first region Z1 occupies the main central area within the first opening K1, with a relatively large area proportion. When differentiating the thickness of the color resist unit 20 in the first region Z1 and the second region Z2, the thickness of the color resist unit 20 in the second region Z2 is mainly adjusted to improve the light emission of the shared sub-pixel sp1 to a wider viewing angle. By setting the first region Z1 to cover the light-emitting device 30 of the shared sub-pixel sp1, the area of ​​the first region Z1 can be appropriately increased. The transmittance of the edge of the first region Z1 is less than that of the second region Z2. The edge of the first region Z1 is used to block part of the light emitted by the light-emitting device 30 at a small viewing angle. This ensures that when viewed at a relatively small viewing angle (such as ±10° or ±8°), the brightness of the shared sub-pixel sp1 and the privacy sub-pixel sp2 is consistent, which can improve the screen flickering phenomenon during switching.

[0052] In some implementations, such as Figure 1As shown, the orthographic projection of the first region Z1 onto the substrate 00 coincides with the orthographic projection of the light-emitting device 30 of the shared sub-pixel sp1 onto the substrate 00. That is, along the first direction a, the distance between the edge of the light-emitting device 30 in the shared sub-pixel sp1 and the edge of the first region Z1 is Δd, where Δd = 0. This embodiment ensures that the first region Z1 is located directly above the light-emitting device 30 in the shared sub-pixel sp1. A relatively complete color resist unit 20 is provided in the first region Z1, ensuring the uniformity of light emitted by the light-emitting device 30 in the forward-looking direction. like Figure 13 As shown, along the first direction a, the distance between the edge of the light-emitting device 30 in the shared sub-pixel sp1 and the edge of the first region Z1 is Δd, where 0 < Δd ≤ 2μm. In this embodiment, a certain distance is set between the edge of the first region Z1 and the edge of the light-emitting device 30, which can utilize the edge position of the first region Z1 to block part of the light emitted by the light-emitting device 30 at a small viewing angle. This ensures that the brightness of the shared sub-pixel sp1 and the privacy sub-pixel sp2 is consistent when viewed from a relatively small viewing angle, thus improving the screen flickering phenomenon during switching. Furthermore, setting Δd ≤ 2μm ensures that there is sufficient width between the first region Z1 and the light-shielding structure 11, ensuring that the width of the second region Z2 meets the requirement of increasing the light output at a large viewing angle.

[0053] like Figure 13 As shown, along the first direction a, the distance between the edge of the light-emitting device 30 in the shared sub-pixel sp1 and the edge of the first region Z1 is Δd, where Δd = h. tanθ, 0°≤θ≤5°, h is the distance from the plane containing color resist unit 20 to the plane containing light-emitting device 30. Combined with... Figure 13 Let angle θ be the angle between the critical ray emitted by the light-emitting device 30 from the edge of the first region Z1 and the viewing direction. This angled ray is refracted inside the panel and finally exits the display panel to form a relatively small viewing angle ray, such as ±10° or ±8°. In this embodiment of the invention, Δd is set to satisfy a certain relationship with h and θ, so that the edge of the first region Z1 can be used to block part of the small viewing angle ray emitted by the light-emitting device 30. As a result, when viewed at a relatively small viewing angle, the brightness of the shared sub-pixel sp1 and the privacy sub-pixel sp2 is consistent, which can improve the screen flickering phenomenon during switching.

[0054] Figure 13 To illustrate the overlap between the first region Z1 and the light-emitting device 30, only the scheme in which the thickness of the color resist unit 20 in the second region Z2 is reduced to 0 is shown. Figure 13 The description of △d in the examples also applies to Figure 2 In the case where a certain thickness of color resist unit 20 is retained in the second region Z2.

[0055] In some embodiments of the present invention, the light-shielding structure 11 includes a black light-shielding material, such as chromium, chromium oxide, or black resin.

[0056] In other embodiments, the light-shielding structure 11 includes at least two color-blocking materials of different colors stacked together. For example, Figure 14 This is a schematic diagram of another display panel provided in an embodiment of the present invention. Figure 14 As shown, the color resist unit 20 is located in the first region Z1, and the area between the color resist unit 20 and the light-shielding structure 11 is the second region Z2. The light-shielding structure 11 includes three types of color resist materials stacked together: a first color resist material 111, a second color resist material 112, and a third color resist material 113. The first color resist material 111, the second color resist material 112, and the third color resist material 113 are respectively one of red, green, and blue color resist materials. The display panel includes red, green, and blue color resist units. The color resist material can be fabricated at the location of the light-shielding structure 11 while the color resist unit is being manufactured. That is, the color resist material layer at the location of the color resist unit and the light-shielding structure 11 is fabricated simultaneously using a patterning process, eliminating the need to fabricate the light-shielding structure 11 separately, thus simplifying the manufacturing process.

[0057] Figure 14 In this embodiment, the light-shielding structure 11 is illustrated by comprising three different colored resist materials stacked together. In other embodiments, the light-shielding structure 11 comprises two different colored resist materials stacked together. In still other embodiments, the light-shielding structure 11 comprises two different colored resist materials stacked together in some locations, and three different colored resist materials stacked together in other locations.

[0058] For example, Figure 15 This is a schematic diagram of another display panel provided in an embodiment of the present invention. Figure 15 As shown, the color resist unit 20 includes a first portion 20-1 and a second portion 20-2. The first portion 20-1 is located in the first region Z1, and the second portion 20-2 is located in the second region Z2. The thickness of the second portion 20-2 is less than the thickness of the first portion 20-1. The light-shielding structure 11 includes a first color resist material 111, a second color resist material 112, and a third color resist material 113 stacked together, for a total of three color resist materials. The first color resist material 111, the second color resist material 112, and the third color resist material 113 are respectively one of a red color resist material, a green color resist material, and a blue color resist material.
