Description

Technical Field

[0002] With the development of display technology, VR (Virtual Reality) display panels have higher and higher requirements for resolution and display, especially for higher resolution display panels.

[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise stated, the directional words such as "upper" and "lower" used generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0034] The embodiments of the present application provide a display panel and a display device, which are described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0035] First, an embodiment of the present application provides a display panel, such as Figure 1As shown, the display panel 100 includes a first substrate 110 and a second substrate 120 that are arranged opposite to each other, and a liquid crystal layer 130 that is arranged between the first substrate 110 and the second substrate 120, that is, one of the first substrate 110 and the second substrate 120 is an array substrate, and the other is a color film substrate. The first substrate 110 and the second substrate 120 are arranged opposite to each other and form a receiving cavity, and the liquid crystal layer 130 is filled in the receiving cavity. During the display process of the display panel 100, the display image of the display panel 100 can be regulated by controlling the deflection angle of the liquid crystal molecules in the liquid crystal layer 130.

[0036] A first photoresist layer 140 and a first shielding layer 150 are disposed on the side of the first substrate 110 facing the liquid crystal layer 130. The first photoresist layer 140 includes a plurality of first photoresists 141, and the first shielding layer 150 includes a plurality of first shielding portions 151. A second shielding layer 160 is disposed on the side of the second substrate 120 facing the liquid crystal layer 130, and the second shielding layer 160 includes a plurality of second shielding portions 161. The first photoresist 141 includes at least one of red photoresist, green photoresist and blue photoresist. When the outgoing light is irradiated to the first photoresist 141, the light of the same color as the first photoresist 141 will pass through the first photoresist 141, and the light of other colors will be filtered out. The first shielding portion 151 and the second shielding portion 161 are used to shield and absorb part of the light to avoid light crosstalk.

[0037] The orthographic projections of the plurality of first shielding portions 151 and the plurality of second shielding portions 161 on the first substrate 110 enclose a plurality of hollow areas S (eg, Figure 6 As shown in the figure, the orthographic projection of the first photoresist 141 on the first substrate 110 corresponds to the hollow area S, and the orthographic projection of each first photoresist 141 on the first substrate 110 is respectively located in a different hollow area S, that is, the orthographic projection of the first blocking portion 151 and the second blocking portion 161 on the first substrate 110 as a whole presents a mesh structure with multiple rows and columns, and the orthographic projection of the first photoresist 141 on the first substrate 110 fills the hollow area S corresponding to the mesh structure, that is, any two adjacent first photoresist 141 are separated by the first blocking portion 151 or the second blocking portion 161 to avoid optical crosstalk between the two adjacent first photoresist 141.

[0038] Since the first blocking layer 150 and the second blocking layer 160 are respectively arranged on different substrate sides, under the setting of the same mesh structure, the density of the first blocking part 151 and the second blocking part 161 in the layer where they are located can be effectively reduced, thereby effectively weakening the regular fluctuation caused by the regular arrangement of the first blocking part 151 and the second blocking part 161, thereby improving the horizontal and vertical stripes phenomenon generated by the display panel 100 during the display process, thereby improving the display quality of the display panel 100.

[0039] In addition, since the density of the first shielding portions 151 and the second shielding portions 161 in their respective layers is reduced, that is, the spacing between adjacent first shielding portions 151 and adjacent second shielding portions 161 in their respective planes is increased, this helps to reduce the difficulty of the manufacturing process of the first shielding portions 151 and the second shielding portions 161, and reduce the bottom residue between adjacent first shielding portions 151 and adjacent second shielding portions 161 during the manufacturing process, thereby helping to improve the aperture ratio and color purity of the display panel 100; at the same time, since shielding layers are provided on the sides where the first substrate 110 and the second substrate 120 are located, it also helps to reduce the overall reflectivity of the display panel 100, so as to further improve the display quality.

[0040] In the embodiment of the present application, the display panel 100 includes a first substrate 110 and a second substrate 120 that are arranged opposite to each other, and a liquid crystal layer 130 that is arranged between the first substrate 110 and the second substrate 120. A first photoresist layer 140 and a first shielding layer 150 are arranged on the side of the first substrate 110 facing the liquid crystal layer 130. The first photoresist layer 140 includes a plurality of first photoresists 141. The first shielding layer 150 includes a plurality of first shielding portions 151. A second shielding layer 160 is arranged on the side of the second substrate 120 facing the liquid crystal layer 130. The second shielding layer 160 includes a plurality of second shielding portions 161. The orthographic projections of the plurality of first shielding portions 151 and the plurality of second shielding portions 161 on the first substrate 110 enclose a plurality of hollow areas S. The orthographic projections of the first photoresist 141 on the first substrate 110 correspond to the hollow areas S, and the orthographic projections of each first photoresist 141 on the first substrate 110 are respectively located in different hollow areas S. The present application divides the blocking layer into a first blocking layer 150 and a second blocking layer 160, and respectively arranges them on different substrate sides, which helps to reduce the density of the first blocking part 151 and the second blocking part 161 in their respective layers, thereby weakening the regular fluctuation caused by the first blocking part 151 and the second blocking part 161, thereby improving the horizontal and vertical stripes phenomenon of the display panel 100 and improving the display quality.

[0041] Optional, such as Figure 2As shown, the display panel 100 includes a second photoresist layer 170, the second photoresist layer 170 is located on the side of the second substrate 120 facing the liquid crystal layer 130, the second photoresist layer 170 includes a plurality of second photoresists 171, the orthographic projections of the second photoresists 171 on the first substrate 110 correspond to the hollow area S, and the orthographic projections of each second photoresist 171 and each first photoresist 141 on the first substrate 110 are respectively located in different hollow areas S, that is, the second photoresist 171 and the first photoresist 141 as a whole are positively projected on the first substrate 110. The projections are distributed in an array, and correspond to the hollow area S formed by the orthographic projection of the first blocking portion 151 and the second blocking portion 161 as a whole on the first substrate 110, that is, the second light resist 171 and the first light resist 141 are located in a grid structure formed by the first blocking portion 151 and the second blocking portion 161, so as to avoid optical crosstalk between two adjacent first light resists 141, two adjacent second light resists 171, and between adjacent first light resists 141 and second light resists 171, thereby ensuring the display quality of the display panel 100.

[0042] It should be noted that since the first photoresist layer 140 is located on the side where the first substrate 110 is located, the second photoresist layer 170 is located on the side where the second substrate 120 is located, and the first photoresist 141 and the second photoresist 171 are also distributed in a regular array as a whole, by arranging the photoresist layers in the display panel 100 on different substrate sides, respectively, the regular fluctuations caused by the first photoresist 141 and the second photoresist 171 can be further weakened, thereby improving the horizontal and vertical stripes phenomenon of the display panel 100 and improving the display quality of the display panel 100.

[0043] Among them, the first photoresist 141 includes one or two of red photoresist, green photoresist and blue photoresist, the second photoresist 171 includes one or two of red photoresist, green photoresist and blue photoresist, and the colors of the first photoresist 141 and the second photoresist 171 are different, that is, the first photoresist 141 includes one or two of red photoresist, green photoresist and blue photoresist, and the second photoresist 171 includes photoresist of the remaining colors among red photoresist, green photoresist and blue photoresist, that is, when color resists of different colors are respectively set on different substrate sides, one of the color photoresists can be set on the side where one of the substrates is located, and the other two color photoresists can be set on the side where the other substrate is located, and the specific colors of the photoresists corresponding to the sides of different substrates can be designed and adjusted according to actual conditions, and there is no special limitation here.

[0044] In some embodiments, Figure 3As shown, the second shielding layer 160 is a blue photoresist layer, that is, it can be understood that the second shielding layer 160 and the second photoresist layer 170 are the same film layer, and the second photoresist layer 170 is a blue photoresist layer, and the blue photoresist plays the role of both light resistance and shielding. Among them, the second shielding part 161 includes a light resistance part 1611 and a shielding part 1612, and the shielding part 1612 and the orthographic projection of the first shielding part 151 on the first substrate 110 enclose a hollow area S, and each light resistance part 1611 and the orthographic projection of each first photoresist 141 on the first substrate 110 are respectively located in different hollow areas S. At this time, the light resistance part 1611 in this embodiment is equivalent to Figure 2 The second photoresist 171 in the shielding portion 1612 is equivalent to Figure 2 The second shielding portion 161 in.

[0045] It should be noted that since the blue photoresist has a lower transmittance to red light and green light, the blue photoresist can play the same role as the second blocking portion 161 for red light and green light. Directly using the blue photoresist as the second blocking portion 161 can omit the manufacturing process of the second blocking portion 161. When manufacturing the blue photoresist, it is only necessary to increase the size of the blue photoresist and use the enlarged part of the blue photoresist to replace the adjacent second blocking portion 161, thereby helping to simplify the manufacturing process of the display panel 100.

[0046] In other embodiments, Figure 6As shown, the first blocking portions 151 are arranged in multiple rows and columns, and the second blocking portions 161 are also arranged in multiple rows and columns, and in the row direction and the column direction, the orthographic projections of the first blocking portions 151 on the first substrate 110 and the orthographic projections of the second blocking portions 161 on the first substrate 110 are alternately arranged. That is, the orthographic projection of the first blocking portion 151 on the first substrate 110 is a mesh structure distributed in multiple rows and columns, and the orthographic projection of the second blocking portion 161 on the first substrate 110 is also a mesh structure distributed in multiple rows and columns. In the row direction, the orthographic projection of the first blocking portion 151 on the first substrate 110 and the orthographic projection of the second blocking portion 161 on the first substrate 110 are alternately arranged row by row, and in the column direction, the orthographic projection of the first blocking portion 151 on the first substrate 110 and the orthographic projection of the second blocking portion 161 on the first substrate 110 are alternately arranged column by column, so that the orthographic projection of the first blocking portion 151 on the first substrate 110 and the orthographic projection of the second blocking portion 161 on the first substrate 110 are alternately arranged as a whole and form a mesh structure. This arrangement enables the spacing between the first blocking portion 151 and the second blocking portion 161 to be increased in both the row direction and the column direction, thereby reducing the density of the first blocking portion 151 and the second blocking portion 161 in their respective layers, weakening the regular fluctuations caused by the first blocking portion 151 and the second blocking portion 161, and further improving the horizontal and vertical stripes phenomenon of the display panel 100, thereby improving the display quality of the display panel 100.

[0047] Optional, such as Figure 4 As shown, the display panel 100 includes a first filling layer 180, which is arranged in the same layer as the first photoresist layer 140. The first filling layer 180 includes a plurality of first filling parts 181, and the first filling parts 181 are arranged corresponding to the second photoresist 171, that is, the first filling parts 181 are used to fill the gaps in the first photoresist layer 140 in the areas corresponding to the second photoresist 171. The display panel 100 further includes a first planarization layer 190, which covers the first photoresist 141 and the first filling portion 181 on the side facing away from the first substrate 110, and the refractive index of the first planarization layer 190 is different from the refractive index of the first filling portion 181, that is, the first planarization layer 190 is used to planarize the surfaces of the first photoresist layer 140 and the first filling layer 180, so as to facilitate the subsequent production of the common electrode and the pixel electrode, thereby avoiding affecting the regulation of the deflection angle of the liquid crystal molecules in the liquid crystal layer 130; and setting the refractive index of the first planarization layer 190 and the refractive index of the first filling portion 181 to be different helps to adjust the exit angle of the exiting light.

[0048] Among them, the side of the first filling portion 181 facing away from the first substrate 110 is a concave surface that is recessed in the direction close to the first substrate 110, and the refractive index of the first filling portion 181 is less than the refractive index of the first planarization layer 190, that is, when the outgoing light is irradiated to the first planarization layer 190 through the first filling portion 181, it will be refracted at the interface between the two and gathered toward the middle area close to the corresponding second photoresist 171, thereby helping to improve the light effect of the corresponding color of the second photoresist 171, and setting the surface of the first filling portion 181 as a concave surface helps to improve the concentration of light.

[0049] Alternatively, the side of the first filling portion 181 facing away from the first substrate 110 is a convex surface that protrudes in the direction away from the first substrate 110, and the refractive index of the first filling portion 181 is less than the refractive index of the first planarization layer 190, that is, when the outgoing light is irradiated to the first planarization layer 190 through the first filling portion 181, it will still be refracted at the interface between the two and gathered toward the middle area of ​​the corresponding second photoresist 171 to improve the light effect of the corresponding color of the second photoresist 171, and setting the surface of the first filling portion 181 as a convex surface helps to make light with a larger range of outgoing angles gathered toward the middle area of ​​the corresponding second photoresist 171.

[0050] It should be noted that the specific shape of the first filling portion 181 and the difference in refractive index between the first filling portion 181 and the first planarization layer 190 can be selected and adjusted according to actual design requirements. It is only necessary to ensure that the coordinated design of the first filling layer 180 and the first planarization layer 190 can effectively improve the light effect of the corresponding color of the second photoresist 171. No special restrictions are made here.

[0051] In some embodiments, Figure 5 As shown, the display panel 100 includes a second filling layer 200, which is arranged in the same layer as the second photoresist layer 170. The second filling layer 200 includes a plurality of second filling parts 201, and the second filling parts 201 are arranged corresponding to the first photoresist 141, that is, the second filling parts 201 are used to fill the gaps in the second photoresist layer 170 in the areas corresponding to the first photoresist 141. The display panel 100 further includes a second planarizing layer 210, which covers the second photoresist 171 and the second filling portion 201 on a side away from the second substrate 120, and the refractive index of the second planarizing layer 210 is different from the refractive index of the second filling portion 201, that is, the first planarizing layer 190 is used to planarize the surface of the second photoresist layer 170 and the second filling layer 200 to avoid affecting the electric field between the first substrate 110 and the second substrate 120, thereby avoiding affecting the regulation of the deflection angle of the liquid crystal molecules in the liquid crystal layer 130; and setting the refractive index of the second planarizing layer 210 and the refractive index of the second filling portion 201 to be different helps to adjust the exit angle of the exiting light.

[0052] Among them, the side of the second filling portion 201 away from the second substrate 120 is a concave surface that is concave in the direction close to the second substrate 120, and the refractive index of the second filling portion 201 is greater than the refractive index of the second planarization layer 210, that is, when the outgoing light passes through the second planarization layer 210 to the second filling portion 201, it will be refracted at the interface between the two and gathered toward the middle area close to the corresponding first photoresist 141, thereby helping to improve the light effect of the color corresponding to the first photoresist 141, and setting the surface of the second filling portion 201 as a concave surface helps to improve the concentration of light.

[0053] Alternatively, the side of the second filling portion 201 facing away from the second substrate 120 is a convex surface that protrudes in the direction away from the second substrate 120, and the refractive index of the second filling portion 201 is greater than the refractive index of the second planarization layer 210, that is, when the outgoing light is irradiated to the second filling portion 201 through the second planarization layer 210, it will still be refracted at the interface between the two and gathered toward the middle area of ​​the corresponding first photoresist 141 to improve the light effect of the corresponding color of the first photoresist 141, and setting the surface of the second filling portion 201 as a convex surface helps to make light with a larger range of outgoing angles gathered toward the middle area of ​​the corresponding first photoresist 141.

[0054] It should be noted that the specific shape of the second filling portion 201 and the difference in refractive index between the second filling portion 201 and the second planarization layer 210 can be selected and adjusted according to actual design requirements. It is only necessary to ensure that the coordinated design of the second filling layer 200 and the second planarization layer 210 can effectively improve the light effect of the corresponding color of the first photoresist 141. No special restrictions are made here.

[0055] Secondly, an embodiment of the present application also provides a display device, which includes a display panel. The specific structure of the display panel refers to the above embodiment. Since the display device adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0056] like Figure 7As shown, the display device 10 includes a display panel 100 and a backlight module 300. The backlight module 300 is used to provide a backlight source for the display panel 100, and the backlight module 300 is located on the side of the first substrate 110 in the display panel 100 away from the second substrate 120 in the display panel 100, that is, the first substrate 110 belongs to the array substrate, the second substrate 120 belongs to the color film substrate, and the backlight module 300 is located on one side of the array substrate. The light emitted by the backlight module 300 as a backlight source passes through the first substrate 110 to reach the liquid crystal layer 130 in the display panel 100. By controlling the deflection angle of the liquid crystal molecules in the liquid crystal layer 130, the light output angle after passing through the liquid crystal layer 130 can be adjusted, and then the light passes through the second substrate 120 to be received by the user, thereby obtaining the display picture of the display panel 100.

[0057] Specifically, the display panel 100 includes a first substrate 110 and a second substrate 120 that are arranged opposite to each other, and a liquid crystal layer 130 arranged between the first substrate 110 and the second substrate 120. A first photoresist layer 140 and a first blocking layer 150 are arranged on the side of the first substrate 110 facing the liquid crystal layer 130. The first photoresist layer 140 includes a plurality of first photoresists 141. The first blocking layer 150 includes a plurality of first blocking portions 151. A second blocking layer 160 is arranged on the side of the second substrate 120 facing the liquid crystal layer 130. The second blocking layer 160 includes a plurality of second blocking portions 161. The orthographic projections of the plurality of first blocking portions 151 and the plurality of second blocking portions 161 on the first substrate 110 enclose a plurality of hollow areas S.
