Description

Technical Field

[0001] This application belongs to the field of display technology, and particularly relates to a color filter substrate, a display panel, and a display device. Background Art

[0002] Electronic products such as mobile phones, tablets, and notebook computers are equipped with functional components such as cameras and ALS (Ambient Light Sensor). The functional components are placed under the TFT-LCD (Thin Film Transistor Liquid Crystal Display) during the assembly of the entire unit. In order to ensure that external light can smoothly pass through the TFT-LCD to reach the functional components, functional component light-transmitting holes are reserved in the TFT-LCD.

[0003] The display panel of the TFT-LCD includes an array substrate (TFT substrate) and a color filter substrate (CF substrate). In order to reduce the optical path loss, each film layer near the functional component light-transmitting hole of the TFT substrate and the CF substrate is removed as much as possible to form a hollowed-out area. A polymer glue with a high transmittance is usually provided in the hollowed-out area, which can improve the depression condition of the hollowed-out area and prevent the occurrence of Newton's rings at the functional component light-transmitting hole.

[0004] However, the polymer glue with a high transmittance has a low viscosity and strong fluidity, which easily causes a low cell gap at the functional component light-transmitting hole and results in a depression condition. Summary of the Utility Model

[0005] This application provides a color filter substrate, a display panel, and a display device, aiming to solve the problem of depression at the functional component light-transmitting hole to at least a certain extent.

[0006] In the first aspect of this application, a color filter substrate is provided, and the color filter substrate includes:

[0008] A transparent glue layer located on the substrate; the orthographic projection of the transparent glue layer on the substrate is located within the hollowed-out area and at least covers the opening area;

[0009] A blocking structure on the same side of the substrate as the transparent glue layer; the orthographic projection of the blocking structure on the substrate is located within the peripheral area and does not coincide with the orthographic projection of the transparent glue layer on the substrate.

[0010] In some embodiments, the barrier structure includes at least one loop of retaining walls, and each loop of retaining walls is disposed around the transparent adhesive layer.

[0011] In some embodiments, the orthographic projection of each loop of retaining walls on the substrate is annular.

[0014] In some embodiments, when each loop of retaining walls includes multiple sub-walls, the sub-walls in adjacent two loops of retaining walls are alternately arranged in the direction of surrounding the transparent adhesive layer.

[0015] In some embodiments, the distance between adjacent two loops of retaining walls is 15 μm to 25 μm.

[0016] In some embodiments, the closest distance between the retaining wall and the transparent adhesive layer is 200 μm to 300 μm.

[0017] In some embodiments, in the direction away from the transparent adhesive layer, the width of the retaining wall is 10 μm to 14 μm.

[0018] In some embodiments, each loop of retaining walls further includes a plurality of first support columns, and the first support columns are located between adjacent two sub-walls of the same loop of retaining walls.

[0019] In some embodiments, the orthographic projection of the sub-wall on the substrate is rectangular, the length direction of the rectangle is the extending direction of the sub-wall, and the extending directions of the sub-walls on both sides of the first support column are not parallel.

[0024] In a second aspect of the present application, a display panel is provided. The display panel includes an array substrate and a color filter substrate provided as in the first aspect.

The orthographic projection of the barrier structure on the substrate is located within the peripheral area and does not coincide with the orthographic projection of the transparent adhesive layer on the substrate. Since the peripheral area surrounds the opening area, the barrier structure located within the peripheral area is at least outside the transparent adhesive layer located within the opening area.

[0047] To enable those skilled in the art to which this application pertains to more clearly understand this application, the following will, in conjunction with the accompanying drawings in the embodiments of this application, clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of this application.

[0048] Please refer to Figure 1 , the TFT-LCD has a cutout area 10, an edge area 20, and a display area 30. The display area 30 occupies most of the area of the TFT-LCD. The cutout area 10 is located on one side of the display area 30 and is at least partially surrounded by the display area 30. The edge area 20 surrounds the display area 30.

[0049] The cutout area 10 includes at least one opening area 11 and a peripheral area 12 surrounding the opening area 11. There are reserved functional component light-transmitting holes in the opening area 11 of the TFT-LCD to ensure that external light can smoothly pass through the TFT-LCD to reach the functional components. The number of the opening areas 11 is the same as the number of functional components equipped in the electronic product. For example, if a notebook computer is equipped with three functional components, namely a camera, an ALS, and a camera indicator light, then the cutout area 10 includes three opening areas 11 as shown in Figure 1 , and a camera hole, an ALS hole, and an indicator light hole are respectively opened.

[0050] Please refer to Figure 2 , in order to reduce the optical path loss, as much as possible, each film layer of the TFT substrate and the CF substrate in the cutout area 10 is removed, and a polymer glue 40 with a high transmittance is provided. The polymer glue 40 can be coated together with a sealant glue 50 provided at the edge of the display area 30 and the edge of the edge area 20 in the corresponding area of the CF substrate, and the polymer glue 40 is cured by means of UV (ultraviolet) curing. However, in order to take into account the high transmittance (exceeding 99%) of the polymer glue 40, the viscosity of the polymer glue 40 is lower than that of the sealant glue 50, and the fluidity is stronger than that of the sealant glue 50, which easily causes the cell gap in the cutout area 10 to be lower than that in the display area 30, and the cutout area 10 appears sunken, and the difference in the cell gap between the cutout area 10 and the display area 30 will cause display defects such as water ripples.

[0051] Please refer to Figure 3 and Figure 4, in the embodiment of the first aspect of the present application, a color filter substrate is provided. The color filter substrate includes a substrate 1, a transparent adhesive layer 2, and a barrier structure 3. The substrate 1 has a hollowed-out area 10. The hollowed-out area 10 includes at least one opening area 11 and a peripheral area 12 surrounding the opening area 11. The transparent adhesive layer 2 is located on the substrate 1. The orthographic projection of the transparent adhesive layer 2 on the substrate 1 is located within the hollowed-out area 10 and at least covers the opening area 11. The barrier structure 3 and the transparent adhesive layer 2 are on the same side of the substrate 1. The orthographic projection of the barrier structure 3 on the substrate 1 is located within the peripheral area 12 and does not coincide with the orthographic projection of the transparent adhesive layer 2 on the substrate 1.

[0052] In practical applications, the edge line of the orthographic projection of the barrier structure 3 on the substrate 1 and the edge line of the orthographic projection of the transparent adhesive layer 2 on the substrate 1 may partially coincide or completely coincide. However, within the orthographic projection of the barrier structure 3 on the substrate 1, it does not coincide with the orthographic projection of the transparent adhesive layer 2 on the substrate 1 at all.

[0053] In the above embodiment, the color filter substrate 1 includes a substrate 1, a transparent adhesive layer 2, and a barrier structure 3. The barrier structure 3 and the transparent adhesive layer 2 are on the same side of the substrate 1. The orthographic projection of the transparent adhesive layer 2 on the substrate 1 is located within the hollowed-out area 10 and at least covers the opening area 11. The orthographic projection of the barrier structure 3 on the substrate 1 is located within the peripheral area 12 and does not coincide with the orthographic projection of the transparent adhesive layer 2 on the substrate 1. In this way, the barrier structure 3 is at least partially outside the transparent adhesive layer 2, and the flow of part of the transparent adhesive layer 2 can be restricted by the barrier structure 3, reducing the difference between the cell thickness of the hollowed-out area 10 and the display area 30, avoiding the lower cell thickness of the hollowed-out area 10, improving the depression situation of the hollowed-out area 10 and the water ripples caused by the cell thickness difference, and finally improving the display effect of the TFT-LCD. In addition, the barrier structure 3 itself can also play a certain supporting role, which is also beneficial to avoiding the lower cell thickness of the hollowed-out area 10 and improving the depression situation of the hollowed-out area 10.

[0054] Exemplarily, the transparent adhesive layer 2 can use a polymer adhesive with a transmittance exceeding 99%.

[0055] Please refer to Figure 3 , in some embodiments, the barrier structure 3 may include at least one ring of retaining walls 31, and each ring of retaining walls 31 surrounds the transparent adhesive layer 2. At least one ring of retaining walls 31 surrounds the outside of the transparent adhesive layer 2, which can effectively prevent the transparent adhesive layer 2 from flowing from the hollowed-out area 10 to other areas, maintaining the cell thickness of the hollowed-out area 10 and avoiding the depression situation due to the lower cell thickness of the hollowed-out area 10.

[0056] Please refer to Figure 3, in some embodiments, the blocking structure 3 may include at least two circles of retaining walls 31, and the at least two circles of retaining walls 31 are arranged at intervals in a direction away from the transparent adhesive layer 2. Surrounding the transparent adhesive layer 2 with at least two circles of retaining walls 31 can block the transparent adhesive layer 2 from flowing from the hollowed-out area 10 to other areas multiple times, completely eliminating the possibility of the transparent adhesive layer 2 flowing from the hollowed-out area 10 to other areas, effectively maintaining the cell thickness of the hollowed-out area 10, and avoiding the situation of depression due to the lower cell thickness of the hollowed-out area 10.

[0057] Please refer to Figure 3 , exemplarily, the blocking structure 3 may include two circles of retaining walls 31, and the two circles of retaining walls 31 are arranged at intervals in a direction away from the transparent adhesive layer 2. Arranging two circles of retaining walls 31 outside the transparent adhesive layer 2 can, on the one hand, effectively block the transparent adhesive layer 2 from flowing from the hollowed-out area 10 to other areas, and on the other hand, can also minimize the space occupied by the blocking structure 3 as much as possible.

[0058] In other embodiments, please refer to Figure 5 , the blocking structure 3 may also include only one circle of retaining wall 31. Please refer to Figure 6 , the blocking structure 3 may further include three circles of retaining walls 31, and the three circles of retaining walls 31 are arranged at intervals in a direction away from the transparent adhesive layer 2.

[0059] Please refer to Figure 6 , exemplarily, the distance a between two adjacent circles of retaining walls 31 may be 15 μm to 25 μm, such as 15 μm, 16 μm, 17 μm, 18 μm, 19 μm, 20 μm, 21 μm, 22 μm, 23 μm, 24 μm, 25 μm, etc. The distance a between two adjacent circles of retaining walls 31 being 15 μm to 25 μm can minimize the space occupied by the blocking structure 3 as much as possible on the premise of effectively blocking the transparent adhesive layer 2 from flowing from the hollowed-out area 10 to other areas.

[0060] Please refer to Figure 6 , exemplarily, the closest distance b between the retaining wall 31 and the transparent adhesive layer 2 may be 200 μm to 300 μm, such as 200 μm, 210 μm, 220 μm, 230 μm, 240 μm, 250 μm, 260 μm, 270 μm, 280 μm, 290 μm, 300 μm, etc. The closest distance b between the retaining wall and the transparent adhesive layer being 200 μm to 300 μm can minimize the space occupied by the blocking structure 3 as much as possible on the premise of effectively blocking the transparent adhesive layer 2 from flowing from the hollowed-out area 10 to other areas.

[0061] Please refer to Figure 6, Exemplarily, in the direction away from the transparent adhesive layer 2, the width c of the retaining wall 31 can be 10 μm to 14 μm, such as 10 μm, 11 μm, 12 μm, 13 μm, 14 μm, etc. The width c of the retaining wall 31 can be 10 μm to 14 μm, which can minimize the space occupied by the blocking structure 3 on the premise of effectively blocking the transparent adhesive layer 2 from flowing from the hollowed-out area 10 to other areas.

[0062] Please refer to Figure 3 , In a possible embodiment, the orthographic projection of each circle of the retaining wall 31 on the substrate 1 can be annular. Each circle of the retaining wall 31 is a completely enclosed structure, which can block all channels for the transparent adhesive layer 2 to flow from the hollowed-out area 10 to other areas, effectively preventing the transparent adhesive layer 2 from flowing from the hollowed-out area 10 to other areas, maintaining the cell thickness of the hollowed-out area 10, and avoiding the depression caused by the lower cell thickness of the hollowed-out area 10.

[0063] Exemplarily, the orthographic projection of each circle of the retaining wall 31 on the substrate 1 can be a square ring (as Figure 3 shown), or it can be a circular ring. When the orthographic projection of each circle of the retaining wall 31 on the substrate 1 is a square ring, the panel area occupied by the hollowed-out area 10 is smaller.

[0064] Please refer to Figure 7 , In another possible embodiment, each circle of the retaining wall 31 can include multiple sub-walls 32 arranged at intervals along the direction of surrounding the transparent adhesive layer 2. One circle of the retaining wall 31 is composed of multiple sub-walls 32 arranged at intervals. During the patterning process, the exposure is more sufficient, ensuring the structural form of the blocking structure 3 and facilitating the realization of the effect of the blocking structure 3.

[0065] Please refer to Figure 8 , In a possible embodiment, the sub-walls 32 in two adjacent circles of the retaining wall 31 can be alternately arranged in the direction of surrounding the transparent adhesive layer 2. Among two adjacent circles of the retaining wall 31, the channel between two adjacent sub-walls 32 in the inner circle of the retaining wall 31 can be blocked by the sub-wall 32 at the corresponding position in the outer circle of the retaining wall 31, so as to effectively block the transparent adhesive layer 2 from flowing from the hollowed-out area 10 to other areas.

[0066] Please refer to Figure 9 , In another possible embodiment, each circle of the retaining wall 31 can further include multiple first support columns 33, and the first support columns 33 are located between two adjacent sub-walls 32 of the same circle of the retaining wall 31. Each circle of the retaining wall 31 is composed of the cooperation of the sub-walls 32 and the first support columns 33. Based on the edge contour of the transparent adhesive layer 2, the sub-walls 32 or the first support columns 33 can be selectively arranged, which can block the transparent adhesive layer 2 from flowing from the hollowed-out area 10 to other areas as much as possible.

[0067] Please refer to Figure 9, Exemplarily, the orthographic projection of the sub-wall 32 on the substrate 1 is rectangular, the length direction of the rectangle is the extension direction of the sub-wall 32, and the extension directions of the sub-walls 32 on both sides of the first support column 33 are not parallel. For example, as Figure 9 shown, the extension directions of the sub-walls 32 on both sides of the first support column 33 are perpendicular to each other. In this way, by arranging the first support column 33 at the corner of the retaining wall 31, it is possible to block the transparent adhesive layer 2 from flowing from the hollowed-out area 10 to other areas as much as possible.

[0068] Please refer to Figure 10 and Figure 11 , in some embodiments, the blocking structure 3 includes a plurality of second support columns 34 arranged at intervals. The blocking structure 3 is composed of a plurality of second support columns 34 arranged at intervals, the transparent adhesive layer 2 surrounds the second support columns 34, and the second support columns 34 can be arranged in the same area as the transparent adhesive layer 2, which is beneficial to reducing the panel area and improving the panel utilization rate.

[0069] Exemplarily, the orthographic projection of the second support column 34 on the substrate 1 can be circular (as Figure 10 shown), can also be rectangular, or can be a closed figure such as an ellipse or a polygon.

[0070] Exemplarily, the density of the second support column 34 is 200 ppm (English: parts per million, Chinese: one in a million) to 500 ppm, such as 200 ppm, 250 ppm, 300 ppm, 350 ppm, 400 ppm, 450 ppm, 500 ppm, etc.

[0071] Please refer to Figure 10 , in a possible embodiment, a plurality of second support columns 34 are arranged in an array on the substrate 1. The second support columns 34 are arranged in an array, which is simple to implement and has a low cost.

[0072] Please refer to Figure 12 , in another possible embodiment, a plurality of second support columns 34 are arranged in multiple rows and multiple columns on the substrate 1, the adjacent two rows of second support columns 34 are staggered in the row direction, and the adjacent two columns of second support columns 34 are staggered in the column direction. The second support columns 34 are staggered, which is beneficial to blocking the transparent adhesive layer 2 from flowing from the hollowed-out area 10 to other areas.

[0073] Exemplarily, the first support column 33 and the second support column 34 can be implemented by PS (English: Photo Spacer, Chinese: spacer), and the retaining wall 31 and the sub-wall 32 can be implemented by PS wall (Chinese: spacer wall).

[0074] In practical applications, when the first support pillar 33 and / or the second support pillar 34 are arranged on the color filter substrate, support pillars can be correspondingly arranged on the array substrate to protect the array substrate when the color filter substrate and the array substrate are vacuum-aligned to form a display panel, and avoid damage to the array substrate caused by the first support pillar 33 and / or the second support pillar 34.

[0075] Please refer to Figure 3 、 Figures 5 - 10 、and Figure 12 ,the color filter substrate further has a display area 30 and a peripheral area 20. The hollowed-out area 10 is located on one side of the display area 30 and is at least partially surrounded by the display area 30. The peripheral area 20 surrounds the display area 30.

[0076] In some embodiments, the color filter substrate further includes an RGB film layer (not shown in the figure) for realizing light filtering. The RGB film layer is located in the display area 30, that is, there is no RGB film layer in the hollowed-out area 10.

[0077] Please refer to Figure 4 and Figure 11 ,in some embodiments, the color filter substrate further includes a BM (English: black matrix, Chinese: black matrix) film layer 101. The BM film layer 101 is located between the substrate 1 and the transparent adhesive layer 2. The BM film layer 101 is provided with a through hole at the opening area 11 to ensure that external light passes through the TFT-LCD to reach the functional component.

[0078] Please refer to Figure 4 and Figure 11 ,in some embodiments, the color filter substrate further includes an OC (English: Open Cell, Chinese: liquid crystal) film layer 102. The OC film layer 102 is located between the BM film layer 101 and the transparent adhesive layer 2.

[0079] Please refer to Figures 3 - 12 ,in some embodiments, the color filter substrate may further include a packaging adhesive layer 103. The packaging adhesive layer 103 is located at the edge of the display area 30 and the edge of the peripheral area 20. Setting the packaging adhesive layer 103 at the edge of the display area 30 can prevent liquid crystal from flowing out. And setting the packaging adhesive layer 103 at the edge of the peripheral area 20 can block the intrusion of external contamination into the display panel.

[0080] In practical applications, in the ODF (English: One Drop Filling, Chinese: liquid crystal dropping) process flow, sealant glue and polymer glue can be coated on the color filter substrate. The sealant glue forms the packaging adhesive layer 103 through thermal curing, and the polymer glue forms the transparent adhesive layer 2 through UV curing. The color filter substrate and the array substrate are vacuum-aligned to form a display panel.

[0081] In some embodiments, the color filter substrate may further include a support structure (not shown in the figure), and the support structure is located in the edge region 20. The support structure may be implemented by PS or PS wall. Exemplarily, the material and size of PS or PS wall in the support structure may be the same as those of the barrier structure 3. In practical applications, the barrier structure 3 may be formed simultaneously with the support structure in the edge region 20.

[0082] Exemplarily, PS may also be provided in the display region 30 to define the position of the liquid crystal. The density of PS in the display region 30 may be less than the density of the second support pillars 34 in the peripheral region 12. For example, the density of the second support pillars 34 in the peripheral region 12 is twice the density of PS in the display region 30.

[0083] Please refer to Figure 13 , in the embodiments of the second aspect of the present application, a display panel is provided. The display panel includes an array substrate 200 and the color filter substrate 100 provided in any of the above embodiments. The array substrate 200 is disposed opposite to the substrate 1, and the transparent adhesive layer 2 and the barrier structure 3 are located between the substrate 1 and the array substrate 200.

[0084] Please refer to Figure 14 and Figure 15 , in some embodiments, the array substrate 200 includes a TFT film layer 201 for realizing light emission. The TFT film layer 201 is located in the display region 10 and the edge region 20, that is, there is no TFT film layer 201 in the hollowed-out region 10.

[0085] Please refer to Figure 14 and Figure 15 , as described above, the color filter substrate 100 further includes an RGB film layer (not shown in the figure) for realizing light filtering, a BM film layer 101, an OC film layer 102, a packaging adhesive layer 103, etc., which will not be elaborated here.
