TECHNICAL FIELD

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

[0002] Since a virtual reality (VR) head-mounted product belongs to near-eye display, and the picture displayed by a liquid crystal display screen needs to be magnified by multiple times by an imaging system before entering the human eye, even if the resolution of the current VR display screen has reached 1000PPI or more, the screen door effect caused by the light shielding structure can still be observed in the whole machine display, such as Figure 1 , which affects the display experience.

[0003] One of the methods to reduce the screen door effect is to improve the resolution, but due to the limitations of process technology and materials, it is difficult to improve the resolution. Therefore, it is necessary to optimize the design of the pixel light shielding structure to reduce the screen door effect. SUMMARY

[0069] This disclosure provides a display panel, see [link to relevant documentation] Figures 2A-2E , Figure 3 , Figures 4A-4C , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the display panel includes:

[0070] Substrate 11;

[0071] The plurality of pixel light transmission regions P comprises a plurality of pixel light transmission region rows H extending along the first direction X and arranged along the second direction Y; at least one of the plurality of pixel light transmission region rows H comprises a first pixel light transmission region P1, a second pixel light transmission region P2, and a third pixel light transmission region P3; a length a3 of the third pixel light transmission region P3 in the second direction Y is less than a length a1 of the first pixel light transmission region P1 in the second direction Y, and less than a length a2 of the second pixel light transmission region P2 in the second direction Y.

[0072] The first shielding structure Z1 is located on one side of the substrate 11, and a projection of the first shielding structure Z1 on the substrate 11 is located between the gaps between the projections of at least some adjacent third pixel light transmission regions P3 on the substrate 11 in the second direction Y.

[0073] In the embodiments of the present disclosure, the length a3 of the third pixel light transmission region P3 in the second direction Y is less than the length a1 of the first pixel light transmission region P1 in the second direction Y, and less than the length a2 of the second pixel light transmission region P2 in the second direction Y, and the first shielding structure Z1 is arranged in the gap between at least some adjacent third pixel light transmission regions P3, which can reduce the brightness difference of the third pixel light transmission region P3 at different positions, make the distribution of the third pixel light transmission region P3 in the entire pixel region more uniform, thereby reducing the screen door effect and improving the visual effect.

[0074] Specifically, the pixel light transmission region P can be understood as the effective display area of the pixel, which can be the area in the pixel region that is not shielded by the shielding structure (such as the light shielding layer, the gate line, the data line, the second shielding metal layer, the black matrix, etc.). Specifically, in one possible implementation, as shown in Figure 2A The black matrix layer 6 has a black matrix opening region 60, wherein the third shielding structure Z3 extending transversely and filled with diagonal lines shields part of the black matrix opening region 60, and the pixel light transmission region P can be the area in the black matrix opening region 60 that is not shielded by the third shielding structure Z3, that is, as shown in Figure 2A

[0075] ​In a possible implementation, the length a1 of the first pixel light-transmitting region P1 in the second direction Y is equal to the length a2 of the second pixel light-transmitting region P2 in the second direction Y, and the third pixel light-transmitting region P3 emits a light wave band range smaller than the light wave band range emitted by the first pixel light-transmitting region P1 and smaller than the light wave band range of the second pixel light-transmitting region P2. In the embodiment of the present disclosure, the length a3 of the third pixel light-transmitting region P3 in the second direction Y is set to be shorter, so as to set the first shielding structure Z1. In addition, compared with the first pixel light-transmitting region P1 and the second pixel light-transmitting region P2, the third pixel light-transmitting region P3 has a smaller light wave band range and a lower brightness, which can effectively reduce the sensitivity of the human eye to the first shielding structure Z1, and can reduce the brightness difference between the positions with and without the spacer 2 between the third pixel light-transmitting regions P3, so that the brightness is more uniformly distributed in the entire pixel region, thereby reducing the screen door effect and improving the visual effect.

[0076] In a possible implementation, referring to Figures 2A-2E 、 Figures 4A-4C , the display panel further includes: a spacer 2 (that is, located in the octagonal region shown in Figure 2A ) in the substrate 11. The orthogonal projection of the spacer 2 on the substrate 11 is located in the gap between the orthogonal projection of the substrate 11 of the second direction Y on the second direction Y. In addition, the orthogonal projection of the spacer 2 on the substrate 11 and the orthogonal projection of the first shielding structure Z1 on the substrate 11 do not overlap. In the embodiment of the present disclosure, compared with the first pixel light-transmitting region P1 and the second pixel light-transmitting region P2, the third pixel light-transmitting region P3 has a smaller light wave band range and a lower brightness, and then the spacer 2 is placed in the gap between the adjacent third pixel light-transmitting regions P3. The brightness difference brought by the spacer 2 is smaller than that when the spacer 2 is placed on the first pixel light-transmitting region P1 and the second pixel light-transmitting region P2, which can further effectively reduce the sensitivity of the human eye to the shielding structure (for example, the black matrix) at the position of the spacer 2, thereby reducing the screen door effect and improving the visual effect.

[0077] Specifically, the third pixel light-transmitting region P3 can be a blue pixel light-transmitting region, the first pixel light-transmitting region P1 can be a red pixel light-transmitting region, and the second pixel light-transmitting region P2 can be a green pixel light-transmitting region. In the embodiment of the present disclosure, the spacer 2 can be first placed in the gap between the adjacent blue pixel light-transmitting regions, which effectively reduces the compensation sensitivity of the human eye to the shielding structure (for example, the black matrix) at the position of the spacer 2 (the brightness of the blue pixel is lower than that of the green pixel and the red pixel, and therefore the brightness difference brought by the spacer 2 when the spacer 2 is placed in the gap between the adjacent blue pixel light-transmitting regions is smaller than that when the spacer 2 is placed on the green pixel and the red pixel, as shown in Figure 9 and Figure 10 , wherein Figure 9 is an analog effect diagram of the spacer 2 placed between the adjacent red pixel light-transmitting regions, Figure 10The simulation effect diagram of the spacer 2 placed between the adjacent blue pixel light transmission areas). In addition, the first shielding structure Z1 can be arranged at the position without the spacer 2 between the adjacent blue pixels, which reduces the brightness difference between the positions with the spacer 2 and the positions without the spacer 2 of the blue pixels, makes the brightness distribution more uniform in the whole pixel area, thereby reducing the screen door effect and improving the visual effect. As shown in Figure 2G If the first shielding structure Z1 is not added, two adjacent bright areas and one larger dark area will appear on the pixel column alternately, thereby presenting a visual effect similar to a brick block, as shown in Figure 2F .

[0078] In a possible implementation, the wavelength range of the light emitted by the third pixel light transmission area P3 can also be greater than the wavelength range of the light emitted by the first pixel light transmission area P1 and the wavelength range of the light emitted by the second pixel light transmission area P2. Specifically, the third pixel light transmission area P3 can be a red pixel light transmission area, the first pixel light transmission area P1 can be a blue pixel light transmission area, and the second pixel light transmission area P2 can be a green pixel light transmission area. That is, the first shielding structure Z1 can also be arranged at the gap between at least two adjacent red pixel light transmission areas, and the spacer 2 can be placed at the gap between the adjacent two red pixel light transmission areas.

[0079] In a possible implementation, as shown in Figures 2A-2E , Figure 3 , Figures 4A-4C , Figure 5 , Figure 6 , Figure 7 and Figure 8 , the first shielding structure Z1 and the spacer 2 are alternately distributed along the second direction Y in the orthographic projection on the substrate 11. Specifically, the first shielding structure Z1 and the spacer 2 can be located in the same column, for example, both located in the column where the third pixel light transmission area P3 is located.

[0080] In a possible implementation, as shown in Figures 2A-2E , Figure 3 , Figures 4A-4C , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the display panel also includes: a second shielding structure Z2; the orthographic projection of the second shielding structure Z2 onto the substrate 11 covers the orthographic projection of the spacer 2 onto the substrate 11; specifically, the second shielding structure Z2 can be used to shield the spacer 2, and the orthographic projection shape of the second shielding structure Z2 onto the substrate 11 can be the same as the orthographic projection shape of the spacer 2 onto the substrate 11. For example, the orthographic projection shape of the spacer 2 onto the substrate 11 can be hexagonal, octagonal, circular, or elliptical; the orthographic projection shape of the second shielding structure Z2 onto the substrate 11 can also be hexagonal, octagonal, circular, or elliptical; the maximum length b1 of the first shielding structure Z1 in the second direction Y is less than the maximum length b2 of the second shielding structure Z2 in the second direction Y.

[0081] Specifically, the ratio of the maximum length b1 of the first shielding structure Z1 in the second direction Y to the maximum length b2 of the second shielding structure Z2 in the second direction Y is greater than or equal to 0.78. Specifically, the orthographic projection of the first shielding structure Z1 onto the substrate 11 is rectangular, and the maximum length b1 of the first shielding structure Z1 in the second direction Y can be the length of the vertical side of the rectangle along the second direction Y; the orthographic projection of the second shielding structure Z2 onto the substrate 11 is octagonal, and the maximum length b2 of the second shielding structure Z2 in the second direction Y can be the distance between two opposite sides of the octagon parallel to the first direction X.

[0082] In one possible implementation, see Figure 3 As shown, the first occlusion structure Z1, the second occlusion structure Z2, and the third occlusion structure Z3 satisfy the following relationship:

[0083] 2(a1+b3)=2a3+b1+b2; where a1 represents the maximum length of the first pixel's light-transmitting area P1 in the second direction Y, a2 represents the maximum length of the second pixel's light-transmitting area P2 in the second direction Y, a3 represents the maximum length of the third pixel's light-transmitting area P3 in the second direction Y, b1 represents the maximum length of the first occlusion structure Z1 in the second direction Y, b2 represents the maximum length of the second occlusion structure Z2 in the second direction Y, and b3 represents the maximum length of the third occlusion structure Z3 in the second direction Y.

It should be noted that the last pixel light-transmitting region row H can be the last pixel light-transmitting region row H in the gate signal scanning direction, that is, the gate scanning signal is loaded on the pixels in the last pixel light-transmitting region row H first, and then loaded on the pixels in the current pixel light-transmitting region row.

[0085] In a possible implementation, referring to Figure 3 As shown, the second shielding structure Z2 satisfies the following relationship:

[0086] x1+y1=b2; wherein b2 represents the maximum length of the second shielding structure Z2 in the second direction Y, x1 represents the distance between the first outer edge w1 and the second outer edge w2 in the second direction Y, the first outer edge w1 is the outer edge of the first-type third pixel light-transmitting region P31 of the mth pixel light-transmitting region row H towards the m-1th pixel light-transmitting region row H and extending along the first direction X, the second outer edge w2 is the outer edge of the first pixel light-transmitting region P1 of the mth pixel light-transmitting region row H towards the m-1th pixel light-transmitting region row H and extending along the first direction X, y1 represents the distance between the third outer edge w3 and the fourth outer edge w4 in the second direction Y, the third outer edge w3 is the outer edge of the second-type third pixel light-transmitting region P32 of the m+1th pixel light-transmitting region row H towards the m+2th pixel light-transmitting region row H and extending along the first direction X, and the fourth outer edge w4 is the outer edge of the first pixel light-transmitting region P1 of the m+2th pixel light-transmitting region row H towards the m+1th pixel light-transmitting region row H and extending along the first direction X.

[0087] In a possible implementation, referring to Figure 3 As shown, the third shielding structure Z3 satisfies the following relationship:

[0088] x2+y2=b1; wherein, b1 represents the maximum length of the first shielding structure Z1 in the second direction Y, x2 represents the difference between the fifth outer edge w5 and the second outer edge w2 in the second direction Y, the fifth outer edge w5 being an outer edge of the second type third pixel light-transmitting region P32 of the mth pixel light-transmitting region row H extending to the side of the m-1th pixel light-transmitting region row H along the first direction X, and y2 represents the difference between the sixth outer edge w6 and the fourth outer edge w4 in the second direction Y, the sixth outer edge w6 being an outer edge of the first type third pixel light-transmitting region P31 of the m+1th pixel light-transmitting region row H extending to the side of the m+2th pixel light-transmitting region row H along the first direction X.

[0089] In a possible implementation, referring to FIG. 1, the second shielding structure Z2 satisfies the following relationship: Figure 3

[0091] y2-b3=x2; wherein, b3 represents the maximum length of the third shielding structure Z3 in the second direction Y.

[0092] In a possible implementation, referring to FIG. 1, the third pixel light-transmitting region P3 satisfies the following relationship: Figure 3

[0093] x1=2x2.

[0094] It should be noted that the above is only an example of the structure shown in FIG. 1 to illustrate the relevant size relationship of the first shielding structure Z1, the second shielding structure Z2, and the third shielding structure Z3. In specific implementation, for the display panel structure corresponding to Figure 3 , Figure 2A , Figure 4A , Figure 5 , Figure 6 , Figure 7 , Figure 8 the relevant size relationship of the first shielding structure Z1, the second shielding structure Z2, and the third shielding structure Z3 can also be satisfied.

[0095] Specifically, the area of the third pixel light-transmitting region P3 is greater than 50% of the area of the first pixel light-transmitting region P1, and the area of the third pixel light-transmitting region P3 is greater than 50% of the area of the second pixel light-transmitting region P2.
