It should be noted that, for clarity, fig. 3 only illustrates filter layer 4, and other film structures of the display panel are not shown in fig. 3.
Specifically, as shown in fig. 3 to 4, the filter unit 4 includes filter units of three colors, the organic light emitting diode 3 also emits light corresponding to the filter units, specifically, the first filter unit 41 corresponds to the first color pixel 31, the second filter unit 42 corresponds to the second color pixel 32, the third filter unit 43 corresponds to the third color pixel 33, and the color of the first filter unit 41 is the same as the color of the first color pixel 31, the color of the second filter unit 42 is the same as the color of the second color pixel 32, and the color of the third filter unit 43 is the same as the color of the third color pixel 33. It should be noted that, the present invention does not specifically limit the pixels of the display panel that specifically use several colors, and only three colors are taken as an exemplary illustration.
Most of the light emitted from the first color pixel 31 is emitted from the first light outlet K1, most of the light emitted from the second color pixel 32 is emitted from the second light outlet K2, most of the light emitted from the third color pixel 33 is emitted from the third light outlet K3, and the width w11 of the first dimming unit 61, the width w22 of the second dimming unit 62, the width w33 of the third dimming unit 63, and the width w44 of the fourth dimming unit 64 are all different, and accordingly, the width w1 of the first light outlet K1 defined by the first dimming unit 61 and the second dimming unit 62, the width w2 of the second light outlet K2 defined by the second dimming unit 62 and the third dimming unit 63, and the width w3 of the third light outlet K3 defined by the third dimming unit 63 and the fourth dimming unit 65 are all different.
The principle of adjusting light rays in the present invention is described below by taking only the second color pixel 32 and the third color pixel 33 as an example, and the dimming unit in the embodiment of the present invention can adjust light rays of all pixels on the display panel, which is not described herein again. When the second color pixel 32 emits light, most of the light L exits from the corresponding filter unit 42, and part of the light L (especially, the light at the edge of the pixel) exits through the filter unit 43, which, if not processed, may cause color shift of the display panel. The light adjusting unit provided in the embodiment of the present invention can block the light L ' passing through the filtering unit 43 from further extending when the light L ' exits, as shown in fig. 4, the light L ' can be blocked by the third light adjusting unit 63; similarly, when the light L of the third color pixel 33 (especially, the light at the edge of the pixel) passes through the filtering unit 42, a part of the light L' can be blocked by the second dimming unit 62. In the display panel provided by the embodiment of the invention, the light blocked by the dimming unit can be reduced by at least two thirds, the emergent light which is blocked can be obviously reduced and is emitted from the display panel, the edge light leakage is weakened, the condition of color cast of the display panel is reduced or avoided, the color mixing effect of the display panel is improved, in addition, the display performance of the display panel can be obviously improved without changing other film layer structures in the display panel, and the display quality of the display panel is improved.
Optionally, please continue to refer to fig. 4, the color of the first filter unit 41 is red, the color of the second filter unit 42 is green, and the color of the third filter unit 43 is blue; the first light outlet K1 is a red light outlet, the second light outlet K2 is a green light outlet, and the third light outlet K3 is a blue light outlet.
It should be noted that, in the embodiment of the present invention, only red, green and blue are taken as examples for description, and in the actual use process, the filter unit may be in other colors, such as magenta, turquoise and indigo, and the present invention is not limited to this.
Optionally, with continued reference to fig. 4, the width w1 of the red light outlet K1, the width w2 of the green light outlet K2, and the width w3 of the blue light outlet K3 satisfy: w1< w2< w 3; w11, w22, w33 and w44 satisfy: w44< w33< w11< w 22.
In the display panel provided by the prior art, because the wavelengths of the blue light and the green light are relatively close, the blue light is more easily emitted from the green light outlet, and the green light is emitted from the blue light outlet, so that the color cast phenomenon of the display panel is caused. In the display panel provided by the embodiment of the invention, the widths of the red light outlet, the green light outlet and the blue light outlet are adjusted by setting different widths of the dimming units. By reducing the width of the red light outlet, the emergent range of red light can be limited, and the color cast of the red light is weakened; similarly, the width of the green light outlet is reduced, the outgoing range of green light can be limited, and the color cast of the green light is weakened. By adjusting the width of the dimming unit, the width of the dimming unit satisfies: w44< w33< w11< w22, so that the widths of the red light outlet, the green light outlet, and the blue light outlet satisfy: w1< w2< w3, thereby further improving color shift of the display panel under different viewing angles, improving color mixing effect of the display panel, improving display performance of the display panel, and improving display quality of the display panel.
It should be noted that, in the embodiment of the present invention, only red, green and blue are taken as examples for description, and in the actual use process, the filter unit may be in other colors, such as magenta, turquoise and indigo, and the present invention is not limited to this.
Optionally, referring to fig. 5, fig. 5 is a schematic cross-sectional structure diagram of another display panel according to an embodiment of the present invention. As shown in fig. 5, in a direction Z perpendicular to the display panel, the height of the first dimming cell 61 is h11, the height of the second dimming cell 62 is h22, the height of the third dimming cell is h33, and the height of the fourth dimming cell is h44, and h11, h22, h33, and h44 are all different.
Optionally, with continued reference to fig. 5, h11, h22, h33, h44 satisfy: h44< h11< h33< h 22.
In the display panel provided by the embodiment of the invention, the height of each dimming unit is different from the heights of the dimming units around the dimming unit, and the emergent angle of light rays of each color is further adjusted by adjusting the heights of the dimming units, so that edge light leakage is reduced, color cast of the display panel possibly appearing at different viewing angles is further improved, the color mixing effect of the display panel is improved, the display performance of the display panel is improved, and the display quality of the display panel is improved.
Optionally, referring to fig. 6, fig. 6 is a schematic cross-sectional structure diagram of another display panel according to an embodiment of the present invention. As shown in fig. 6, in the direction Z perpendicular to the display panel, the height of the light shielding unit 50 overlapping the first light adjusting unit 61 is b1, the height of the light shielding unit 51 overlapping the second light adjusting unit 62 is b2, the height of the light shielding unit 52 overlapping the third light adjusting unit is b3, the height of the light shielding unit 53 overlapping the fourth light adjusting unit is b4, and b1, b2, b3, b4 satisfy: b4< b1< b3< b 2.
In the display panel provided by the embodiment of the invention, the height of each dimming unit is different from the heights of the dimming units around the dimming unit, the heights of the light shading units overlapped with the dimming units are also different, the dimming unit with the higher height is overlapped with the light shading unit with the higher height, and the dimming unit with the lower height is overlapped with the light shading unit with the lower height, so that the emergent angle of light can be further adjusted, the edge light leakage is reduced, the color cast which possibly occurs in the display panel is improved, the color mixing effect of the display panel is improved, the display performance of the display panel is improved, and the display quality of the display panel is improved.
Optionally, please continue to refer to fig. 6, the height of the dimming unit 6 is 0.5 μm to 10 μm; in the direction Z perpendicular to the display panel, the distance between the dimming unit 6 and the light shielding unit overlapped with the dimming unit is 0-1000 μm.
Specifically, the inventors found in the research that the heights of the dimming cells 6 may be different, the heights of the dimming cells 6 may be varied between 0.5 μm and 10 μm, and similarly, the heights of the light shielding cells overlapping the dimming cells 6 may be varied between 0.5 μm and 10 μm, and the distances between the dimming cells and the light shielding cells overlapping the dimming cells may be varied between 0 μm and 1000 μm. Such a design can greatly improve the quality and performance of the display panel.
In the prior art, light is filtered by a polarizer, the thickness of the polarizer is at least dozens of micrometers, the thickness of the display panel is thick, and the thicker display panel is not beneficial to folding due to larger stress on a bending region when being folded. The display panel of the embodiment of the invention can play a role in filtering light only by adding one layer of dimming unit without changing other film layer structures in the display panel. The inventor finds in research that the thickness of the dimming unit floats between 0.5 and 10 micrometers, namely the maximum thickness of the dimming unit is 10 micrometers, so that the thickness of the display panel can be obviously reduced, the stress on a bending area of the display panel during folding is reduced, and the flexible display panel is favorably manufactured; meanwhile, the light adjusting unit can adjust the emergent angle of light to weaken the edge light leakage, improve the color cast phenomenon of the display panel, improve the color mixing effect of the display panel, improve the display performance of the display panel and improve the display quality of the display panel.
Optionally, referring to fig. 7, fig. 7 is a schematic cross-sectional structure diagram of another display panel according to an embodiment of the present invention. As shown in fig. 7, along the first direction X, a height s1 of a side of the fourth dimming cell 64 close to the third light outlet K3 and a height s2 of a side of the fourth dimming cell 64 far from the third light outlet K3 satisfy: s1< s 2; in the first direction X, the height b44 of the side of the light shielding unit 53 overlapping with the fourth dimming unit 64 close to the blue filter unit 43 and the height b41 of the side of the light shielding unit 53 overlapping with the fourth dimming unit 64 far from the blue filter unit 43 satisfy: b44< b 41.
Specifically, as shown in fig. 7, the pixels on the display panel are arranged in red, green, and blue, and the color of the pixel adjacent to the blue pixel is red, so that the heights of the dimming units 64 between the blue light outlets and the adjacent red light outlets are not consistent, specifically, the height s1 of the side of the dimming unit 64 close to the blue light outlet is smaller than the height s2 of the side of the dimming unit 64 away from the blue light outlet; accordingly, the height b41 of the light shielding unit 53 on the side close to the blue filter unit 43 is smaller than the height b42 of the light shielding unit 53 on the side away from the blue filter unit 43. Alternatively, the dimming unit and the shading unit with different heights can be manufactured by using a half-tone mask plate for exposure.
It should be noted that, in the embodiment of the present invention, only red, green and blue are taken as examples for description, and in the actual use process, the filter unit may be in other colors, such as magenta, turquoise and indigo, and the present invention is not limited to this.
The embodiment of the present invention only takes fig. 7 as an example to provide a feasible setting method for the dimming unit and the light shielding unit between two adjacent pixels (for example, blue and red), and it can be understood that the dimming unit and the light shielding unit between two adjacent pixels may also adopt other setting methods, for example, the first dimming unit and the fourth dimming unit are consistent in height, and the present invention is not limited to this.
Optionally, please refer to fig. 8, where fig. 8 is a schematic cross-sectional structure diagram of another display panel according to an embodiment of the present invention. As shown in fig. 8, a plurality of dimming cells 6 are located on one side of the filter layer 4 close to the array substrate 1; the plurality of dimming cells 6 are multiplexed as touch electrodes.
Specifically, in the display panel provided in the embodiment of the present invention, the light modulation unit is disposed on one side of the filter layer close to the array substrate, and the light modulation unit is reused as the touch electrode, and light modulation is performed by adjusting the height and/or width of the touch electrode, so that not only can the angle of light emergence be adjusted, the edge light leakage be reduced, and color cast of the display panel be improved, but also the film structure of the display panel can be further reduced, so that the display panel is thinner and lighter, the display performance of the display panel is improved, and the display quality of the display panel is improved. The method of adjusting light by using the touch electrode is similar to the method of adjusting light in other embodiments of the present invention, and is not described herein again. Optionally, the touch electrode may be a metal mesh structure. It should be noted that, the dimming unit herein is made of opaque metal, or a combination of opaque material and transparent metal, or similar conductive and opaque material, and the invention is not limited in this respect.
