Description

TECHNICAL FIELD

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

[0002] Thin film transistor liquid crystal display (TFT-LCD) has become the mainstream in the field of display due to its advantages of light and thin, energy saving, high display quality and mature and stable manufacturing process. With the increasing demand for display effect, flexible display is attracting more and more attention.

[0003] Currently, flexible display generally uses flexible polyimide (PI) instead of traditional glass as the substrate to realize flexible display. However, for liquid crystal display, the display effect is greatly affected by the cell gap and the liquid crystal deflection state. When the liquid crystal display with flexible polyimide as the substrate is bent, the cell gap and the liquid crystal deflection state of the pixel points in the bending area are likely to change, resulting in significant deterioration of the display effect in the bending area. SUMMARY

At least a portion of the spacer pillars are disposed at the intersection of the first rib and the second rib.

[0011] Optionally, the first substrate may further include a rigid base layer and a first light-shielding layer, wherein the first substrate is the flexible base layer.

[0012] Optionally, the opposing substrate further includes a rigid color filter layer and a second light-shielding layer.

[0040] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present application, and should not be construed as limiting the present application.

[0041] Example 1

[0042] See Figure 1 , Figure 4 and Figure 5As shown, in this embodiment, the display panel includes an array substrate 100 and an opposing substrate 200 disposed opposite each other, and a liquid crystal layer 300 disposed between the array substrate 100 and the opposing substrate 200. Furthermore, the display panel may also include a sealant (not shown), with the liquid crystal layer 300 located within the area enclosed by the sealant.

[0043] Both the array substrate 100 and the opposing substrate 200 include a substrate. The substrate of the array substrate 100 is a first substrate 110, and the substrate of the opposing substrate 200 is a second substrate 210. Both the first substrate 110 and the second substrate 210 include a flexible base layer 111, which is made of a flexible material, such as polyimide.

[0044] At least one of the first substrate 110 and the second substrate 210 further includes a rigid base layer 112 and a first light-shielding layer 113. The flexible base layer 111 includes a plurality of spaced-apart pixel regions 1111 and light-shielding regions 1112 located between the pixel regions 1111. The rigid base layer 112 includes a plurality of rigid substrate units 1121 located in the pixel regions 1111. The first light-shielding layer 113 is located in the light-shielding regions 1112. The rigid base layer 112 is made of a nearly rigid material, such as glass or transparent ceramic. The first light-shielding layer 113 may be made of black photoresist and may be bent along with the flexible base layer 111.

[0045] In this embodiment, the display panel includes an array substrate 100, a liquid crystal layer 300, and a counter substrate 200 arranged sequentially. Both the array substrate 100 and the counter substrate 200 include a substrate, which includes a flexible base layer 111. At least one of the array substrate 100 and the counter substrate 200 further includes a rigid base unit 1121 and a first light-shielding layer 113 on its substrate. The rigid base unit 1121 is disposed in the pixel area 1111 of the flexible base layer 111, and the first light-shielding layer 113 is disposed in the light-shielding area 1112 of the flexible base layer 111. The rigid base unit 1121 is almost inflexible, while the first light-shielding layer 113 can bend with the flexible base layer 111. Therefore, when the display panel is bent, it is mainly the light-shielding area 1112 that bends and deforms, while the thickness of the liquid crystal cell and the liquid crystal deflection state of the pixel area 1111 change little or not at all, thus improving the display effect of the display panel.

[0046] See Figures 2 to 5As shown, when fabricating the substrate, a flexible base layer 111 can be formed on one side of the substrate, such as glass, through a coating process. Photoresist is coated on the other side of the substrate, and then patterned using photolithography. The substrate is then etched with acid; areas not protected by the photoresist are etched by the acid. Finally, the photoresist is removed to form a rigid base layer 112. The flexible base layer 111 is a full-surface film layer, while the rigid base layer 112 is a partial-surface film layer. For example, when the substrate is glass, an etching solution composed of 30% HF, 15% H2SO4, 10% HCl, 20% NH4HF2, and deionized water can be used.

[0047] After forming the rigid substrate layer 112, black photoresist can be coated, and then the portion of the black photoresist located in the pixel area 1111 can be etched to form the first light-shielding layer 113. The black photoresist fills the gaps between the rigid substrate units 1121 and is flush with the rigid substrate layer 112, forming a substrate with a flat bearing surface. Before the black photoresist, the substrate can be etched with an etching solution to thin it. When the substrate is a glass substrate, the glass thickness can be 500 micrometers. When the substrate is a combination of the flexible substrate layer 111, the rigid substrate layer 112, and the first light-shielding layer 113, the rigid substrate layer 112 can be thinned to 20 micrometers to 150 micrometers, thereby reducing the amount of black photoresist used. At the same time, because the black photoresist is thinner, its flexibility is better.

[0048] See Figure 1 , Figure 4 and Figure 5 As shown, both the first substrate 110 and the second substrate 210 include a rigid base layer 112 and a first light-shielding layer 113. The opposing substrate 200 can be a color filter substrate, and the opposing substrate 200 also includes a color filter layer and a black matrix. The color filter layer is made using color photoresist, and the color photoresist is baked at a temperature of 230°C for 20 minutes. The hardness of the formed color filter layer can reach 3H to 4H, which is lower than the hardness of glass. The opposing substrate 200 may also include a second planarization layer 240 and a common electrode layer 250. The second planarization layer 240 is formed on the side of the color filter layer and the black matrix away from the second substrate 210, and the common electrode layer 250 is formed on the side of the second planarization layer 240 away from the second substrate 210.

[0049] The rigid substrate unit 1121 is almost inflexible, while the first light-shielding layer 113 can bend along with the flexible substrate layer 111. Therefore, when the display panel is bent, it is mainly the light-shielding area 1112 that bends and deforms. Both the first substrate 110 and the second substrate 210 include a rigid substrate layer 112 and a first light-shielding layer 113. Compared with the first substrate 110 and the second substrate 210, which include a rigid substrate layer 112, the pixel area 1111 is less prone to bending and deformation. The cell thickness and liquid crystal deflection state of the pixel area 1111 change little or not at all, thus improving the display effect of the display panel.

[0050] It should be noted that the color filter layer can be disposed on the opposing substrate 200, but is not limited to this. COA (Color Filter on Array) technology can also be used to dispose of the color filter layer on the array substrate 100, depending on the specific circumstances.

[0051] The liquid crystal display panel using COA technology does not have the alignment problem between the color filter substrate and the array substrate 100, so it can reduce the difficulty of the cell alignment process in the display panel manufacturing process and avoid errors during cell alignment. When using COA technology, the black matrix can be designed with a narrow linewidth, which improves the aperture ratio.

[0052] See Figure 1 , Figure 4 and Figure 5 As shown, the display panel also includes spacer pillars 400 disposed between the array substrate 100 and the opposing substrate 200. The opposing substrate 200 is positioned above, and the array substrate 100 is positioned below. At least a portion of the spacer pillars 400 surround the edge of the rigid substrate unit 1121 and are disposed between two opposing rigid substrate units 1121. That is, for each rigid substrate unit 1121, at least a portion of the spacer pillars 400 overlap with the rigid substrate unit 1121 in their orthographic projection onto the rigid substrate layer 112. For example, one spacer pillar 400 is provided at each of the four corners of each rigid substrate layer 112 for support.

[0053] By supporting two opposing rigid base units 1121 with spacer pillars 400, when the display panel is bent, the light-shielding area 1112 will bend and deform, while the pixel area 1111 is almost unaffected. The thickness of the liquid crystal cell and the liquid crystal deflection state of the pixel area 1111 do not change, thus improving the display effect of the display panel.

[0054] See Figure 6 As shown, in some embodiments, one end of a portion of the spacer post 400 supports two adjacent rigid substrate units 1121. For example, the upper end of the spacer post 400 supports two adjacent rigid substrate units 1121 on the opposing substrate 200, and the lower end of the spacer post 400 supports two adjacent rigid substrate units 1121 on the array substrate 100. That is, the orthographic projection of the spacer post 400 onto the rigid substrate layer 112 of the array substrate 100 overlaps with the two adjacent rigid substrate units 1121, and the orthographic projection of the spacer post 400 onto the rigid substrate layer 112 of the opposing substrate 200 overlaps with the two adjacent rigid substrate units 1121.

[0055] By supporting two adjacent rigid base units 1121 with a spacer pillar 400, when the display panel is bent, the light-shielding area 1112 will bend and deform, while the pixel area 1111 is almost unaffected. The thickness of the liquid crystal cell and the liquid crystal deflection state of the pixel area 1111 do not change, which improves the display effect of the display panel and reduces the number of spacer pillars 400.

[0056] See Figure 7 and Figure 8 As shown, the array substrate 100 further includes a first metal layer 120, a gate insulating layer 130, an active layer 140, a second metal layer 150, a first planarization layer 160, and a pixel electrode layer 170 sequentially formed on the first substrate 110. The first metal layer 120 includes a gate and a common line, and the second metal layer 150 includes a source and a drain. The pixel electrode layer 170 includes a pixel electrode, which includes a first strut 171 arranged in the row direction and a second strut 172 arranged in the column direction, i.e., the first strut 171 and the second strut 172 intersect in a cross shape. At least a portion of the spacer pillars 400 are disposed at the intersection of the first strut 171 and the second strut 172. The spacer pillars 400 disposed at the strut intersection have minimal impact on the liquid crystal molecules.

[0057] The spacer pillar 400 is located at the intersection of the first keel 171 and the second keel 172. When the display panel is bent, the light-shielding area 1112 will bend and deform, while the pixel area 1111 is almost unaffected. The thickness of the liquid crystal cell and the liquid crystal deflection state of the pixel area 1111 do not change, thus improving the display effect of the display panel. At the same time, the spacer pillar 400 located around the rigid base unit 1121 can be reduced, thus reducing the number of spacer pillars 400.

[0058] It should be noted that the orthographic projection of the spacer pillar 400 on the rigid substrate layer 112 may overlap with the rigid substrate unit 1121, but it is not limited to this. The orthographic projection of the spacer pillar 400 on the rigid substrate layer 112 may also be within the light-shielding area 1112, depending on the specific situation. The spacer pillar 400 supports the rigid substrate unit 1121, but the spacer pillar 400 and the rigid substrate unit 1121 are not in direct contact. On the array substrate 100 side, the spacer pillar 400 indirectly supports the rigid substrate unit 1121 through the first metal layer 120, the gate insulating layer 130, the active layer 140, the second metal layer 150, the first planarization layer 160, etc. On the opposing substrate 200 side, the spacer pillar 400 indirectly supports the rigid substrate unit 1121 through the second planarization layer 240, the black matrix, etc.

[0059] Example 2

[0060] The main difference between Embodiment 2 and Embodiment 1 is that the first substrate 110 and the second substrate 210 have the same structure in Embodiment 1, while the first substrate 110 and the second substrate 210 have different structures in Embodiment 2.

[0061] See Figure 1 and Figure 9 As shown, the first substrate 110 includes a flexible base layer 111, a rigid base layer 112 and a first light-shielding layer 113, and the second substrate 210 includes a flexible base layer 111, but does not include a rigid base layer 112 and a first light-shielding layer 113, that is, the second substrate 210 is a flexible base layer 111.

[0062] The second substrate 210 includes a flexible base layer 111, but does not include a rigid base layer 112 and a first light-shielding layer 113. The structure of the opposing substrate 200 is simpler, which can reduce the manufacturing cost of the opposing substrate 200, and thus reduce the manufacturing cost of the display panel.

[0063] See Figure 9 As shown, the opposing substrate 200 further includes a rigid color filter layer 220 and a second light-shielding layer 230. The rigid color filter layer 220 includes red filter units, green filter units, and blue filter units, which are respectively disposed in multiple pixel areas 1111. The second light-shielding layer 230 is disposed in the light-shielding area 1112. Both the rigid color filter layer 220 and the second light-shielding layer 230 are non-uniform film layers. The rigid color filter layer 220 is almost inflexible, while the second light-shielding layer 230 can be bent with the flexible substrate layer 111.

[0064] By replacing the rigid base layer 112 with a rigid color filter layer 220, the second substrate 210 does not need to have a rigid base layer 112, and the opposing substrate 200 can reduce one structural layer, thereby reducing the thickness of the display panel and the manufacturing cost of the display panel.

[0065] See Figure 9 As shown, the red filter unit includes red glass, the green filter unit includes green glass, and the blue filter unit includes blue glass. In other words, the rigid color filter layer 220 is made of colored glass to achieve RGB display.

[0066] By using colored glass to make a rigid color film layer 220, the second substrate 210 does not need to have a rigid base layer 112, and the opposing substrate 200 can reduce one structural layer, which can reduce the thickness of the display panel and the manufacturing cost of the display panel.

[0067] In some embodiments, the red filter unit includes a red photoresist, the green filter unit includes a green photoresist, and the blue filter unit includes a blue photoresist. That is, the rigid color filter layer 220 is made using colored photoresist to achieve RGB display. The hardness of the red, green, and blue photoresist is greater than 5H; for example, the hardness of the red, green, and blue photoresist is all between 5H and 6H. The rigid color filter layer 220 is made using colored photoresist, baked at 250°C for 30–40 minutes, resulting in a rigid color filter layer 220 with a hardness of 5H–6H, reaching the hardness of glass.

[0068] By using colored photoresist to fabricate a rigid color filter layer 220, the second substrate 210 does not need to have a rigid base layer 112, and the opposing substrate 200 can reduce one structural layer, thereby reducing the thickness of the display panel and the manufacturing cost of the display panel.

[0069] It should be noted that the rigid color filter layer 220 can be made of colored glass and colored photoresist, but is not limited to these. The rigid color filter layer 220 can also be made of colored ceramic or other colored inorganic materials, as long as it can filter the light of the backlight module and realize RGB display. The specific choice depends on the situation.

[0070] Example 3

[0071] This application also provides a display device, see [link to relevant documentation] Figure 10 As shown, the display device includes a display panel 10 and a backlight module 20. The display panel 10 includes the display panel 10 disclosed in Embodiment 1 and Embodiment 2. The backlight module 20 is disposed on the light-incident side of the display panel 10, that is, on the side of the array substrate 100 of the display panel 10.

[0072] The display device includes a display panel 10, which comprises an array substrate 100, a liquid crystal layer 300, and a counter substrate 200 arranged sequentially. Both the array substrate 100 and the counter substrate 200 include a substrate, which includes a flexible base layer 111. At least one of the array substrate 100 and the counter substrate 200 further includes a rigid substrate unit 1121 and a first light-shielding layer 113. The rigid substrate unit 1121 is disposed in the pixel region 1111 of the flexible base layer 111, and the first light-shielding layer 113 is disposed in the light-shielding region 1112 of the flexible base layer 111. The rigid substrate unit 1121 is almost inflexible, while the first light-shielding layer 113 can bend with the flexible base layer 111. Therefore, when the display panel is bent, primarily the light-shielding region 1112 deforms, while the cell thickness and liquid crystal deflection state of the pixel region 1111 change little or not at all, improving the display effect of the display panel 10. The display panel 10, used in a display device, can improve the display effect of the display device.
