Abstract
Description
Technical Field
[0001] The present application relates to the field of display technology, and in particular to a display panel and a display device. Background Art
[0002] With the development of display technology, people are pursuing higher and higher display quality of display devices, and people's requirements for display effects are increasing day by day. High contrast, high color gamut, low color deviation, no light leakage, etc. are all research directions. Among them, narrow borders or even borderless display screens have become one of the highlights of display screen design. But technical problems with narrow borders also come along. For example, as the border gradually becomes narrower, the ability of the display panel to resist water vapor intrusion will gradually deteriorate. In response to water vapor intrusion, the black matrix is generally grooved to increase the water vapor channel and reduce the risk of water vapor intrusion, but another new problem will also arise. After the black matrix is grooved, the groove will appear as a bright line due to light transmission. When adjusting the position accuracy of the polarizer, the machine may not be able to accurately grasp the polarizer due to the influence of the bright line, or the position accuracy is not adjusted in place, and the polarizer will have a poor offset problem.

Because after the groove is opened, the groove will directly transmit light, thereby forming a bright line on the black matrix. If this part of the bright line is not staggered with the grabbing and identifying area, then when the machine grabs and adjusts the position of the polarizer, it may be supposed to identify the grabbing and identifying area on the polarizer, but it mistakenly identifies the bright line part, resulting in misgrabbing or incorrect adjustment of the mobile polarizer, which then leads to poor offset and even light leakage of the display panel.

The following description is given to enable any technician in the field to implement and use the present application. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, known structures and processes are not elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles disclosed in this application.
[0031] See also Figure 1 and Figure 2 , an embodiment of the present application provides a display panel, comprising:
[0032] Array substrate 3;
[0033] A color filter substrate 1 arranged opposite to the array substrate 3;
[0034] A black matrix 11 is disposed between the array substrate and the color filter substrate, and a groove 111 is disposed on the black matrix 11;
[0035] A polarizer with a grabbing and identifying area is provided on the color filter substrate 1 and / or the array substrate 3, and is orthographically projected from the polarizer toward the black matrix 11, and the orthographic projection of the polarizer is at least partially located in the black matrix 11;
[0036] The groove 111 extends along the edge of the black matrix 11 , and the orthographic projection of the groove 111 toward the array substrate 3 has no overlapping area with the orthographic projection of the grabbing and identifying area toward the array substrate 3 .
[0037] The technical means provided by the present application is mainly to open a groove 111 on the black matrix 11 that is staggered from the grabbing and identifying area, so that the groove 111 can not only prevent the intrusion of water vapor, but also avoid the recognition impact caused by the grabbing and offset of the polarizer due to the groove 111. In detail, it is mainly to open the groove 111 on the edge of the black matrix 11, so as to prevent water vapor from penetrating into the display area of the panel, causing corrosion or other adverse effects on the circuits, components, etc. in the display area; and then by staggering the opening position of the groove 111 from the grabbing and identifying area, it can effectively avoid the subsequent misrecognition of the grabbing and identifying of the polarizer. After the groove 111 is opened, light will be directly transmitted through the groove 111, thereby forming a bright line on the black matrix 11. If this part of the bright line is not offset from the grabbing and identifying area, then when the machine grabs and adjusts the position of the polarizer, it may mistakenly identify the bright line part instead of the grabbing and identifying area on the polarizer, resulting in misgrabbing or incorrect adjustment of the mobile polarizer, which in turn causes poor offset and even light leakage in the display panel.
[0038] It should be noted that the misidentification between the grabbing and identifying area and the bright line is because the machine mainly identifies the polarizer through the light at the edge of the polarizer. If the grabbing and identifying area overlaps with the bright line or is too close to it, it may cause the machine to misidentify. In this embodiment, the grabbing and identifying area mainly includes the side reflective part of the polarizer. The side reflective part of the polarizer shows brightness, thereby achieving grabbing and identifying.
[0039] In some embodiments, the polarizer includes a first polarizer 2 and a second polarizer 4, the first polarizer 2 is disposed on a side of the color filter substrate 1 away from the array substrate 3, the second polarizer 4 is disposed on a side of the array substrate 3 away from the color filter substrate 1, the grabbing and identifying area of the first polarizer 2 is a first grabbing and identifying area 21, and the grabbing and identifying area of the second polarizer 4 is a second grabbing and identifying area 41;
[0040] Among them, when projected from the first polarizer 2 toward the black matrix 11, the orthographic projection of the first polarizer 2 is located in the black matrix 11, when projected from the second polarizer 4 toward the black matrix 11, the orthographic projection of the second polarizer 4 is at least partially located in the black matrix 11, and the groove 111 is staggered with the first grabbing and identification area 21 and the second grabbing and identification area 41, that is, the orthographic projection of the first grabbing and identification area 21 and the orthographic projection of the second grabbing and identification area 41 have no overlapping area.
[0041] As for the black matrix 11 , it can be disposed on the color filter substrate 1 , or on the array substrate 3 , or on both the color filter substrate 1 and the array substrate 3 , which is not limited here.
[0042] In some embodiments, a plurality of grooves 111 are provided and are spaced along the edge of the black matrix 11, a plurality of first grabbing and identifying areas 21 are provided and are spaced along the edge of the first polarizer 2, and along the edge of the color film substrate 1, the first grabbing and identifying area 21 is located between two adjacent grooves 111. Multiple grooves 111 are provided at the edge of the black matrix 11, which is conducive to the grooves 111 forming a water vapor-proof area on the periphery of the black matrix 11, and covering the entire black matrix 11 as much as possible. Although there is a gap between adjacent black matrices 11, the gap has little effect on the intrusion of water vapor, because the gap distance is small, and only enough space is required for the machine to identify the position of the first polarizer 2. The first grabbing and identifying area 21 is provided between two adjacent grooves 111, and the gap here refers to projecting the grooves 111 and the first grabbing and identifying area 21 into the same plane. The first grabbing and identifying area 21 is set between the two grooves 111, which will not widen the outer dimensions of the display panel and can meet the requirements of a narrow frame. In addition, the first grabbing and identifying area 21 is located between two adjacent grooves 111, which means that there is a black matrix 11 corresponding to the first grabbing and identifying area 21, which can have a shading effect, thereby avoiding misrecognition of the machine due to light transmission.
[0043] Furthermore, the first polarizer 2 is rectangular, and the black matrix 11 is square, which can better match the black matrix 11. There are four grooves 111, and four first grabbing and identifying areas 21. The four grooves 111 are respectively arranged on the four borders of the black matrix 11, and the four first grabbing and identifying areas 21 are respectively located at the four corners of the first polarizer 2. Along the four borders of the black matrix 11, two adjacent grooves 111 are arranged at intervals to define an identification avoidance area 1111, and each first grabbing and identifying area 21 is located in an identification avoidance area 1111. When the machine identifies and grabs the first polarizer 2, it only needs to identify the four corners of the first polarizer 2 and grab the four corners. Compared with being set in the middle of the side of the first polarizer 2 or other positions, the four corners are more convenient to identify and grab. Along the four borders of the black matrix 11, two adjacent grooves 111 are arranged at intervals to define an identification avoidance area 1111, which means that a groove 111 is opened on each of the four sides of the black matrix 11, and the groove 111 extends along the edge until it is close to the position of the corner when the first polarizer 2 is arranged on the black matrix 11. The two adjacent grooves 111 are the grooves 111 opened on the adjacent sides of the black matrix 11. The interval between adjacent grooves 111 is equivalent to that two adjacent grooves 111 are disconnected at the connection point, and the disconnection point is aligned with the first grabbing and identifying area 21, so as to avoid light leakage caused by the grooves 111 opened in the black matrix 11 at the first grabbing and identifying area 21, thereby interfering with the machine grabbing and identifying.
[0044] In some embodiments, see Figure 2 , Figure 2 Schematic diagram of the structure of the display panel provided in one embodiment of the present application (second viewing angle), the second viewing angle is the upward viewing angle of the display panel, and the dotted lines in the figure represent objects that cannot be seen from the second viewing angle. The display panel also includes an array substrate 3 and a second polarizer 4. The array substrate 3 and the color filter substrate 1 are arranged in alignment and spaced apart, and the second polarizer 4 is arranged on the side of the array substrate 3 away from the color filter substrate 1, and the second polarizer 4 has a second grabbing and identifying area 41;
[0045] Among them, from the orthographic projection of the second polarizer 4 toward the black matrix 11, the orthographic projection of the second polarizer 4 is at least partially located in the black matrix 11, and the orthographic projection of the groove 111 toward the array substrate 3 has no overlapping area with the orthographic projection of the second grabbing and identification area 41 toward the array substrate 3.
[0046] The groove 111 and the second grabbing and identifying area 41 in this embodiment are similar to the groove 111 and the first grabbing and identifying area 21 mentioned above, because the display panel is generally provided with polarizers on its two opposite sides, that is, the first polarizer 2 and the second polarizer 4 mentioned above, so it is inevitable that the machine needs to adjust the recognition and grabbing accuracy of the two polarizers respectively to avoid light leakage in the display panel. This embodiment is mainly through the opening of the groove 111 staggered with the second grabbing and identifying area 41 on the black matrix 11, so that the groove 111 can not only prevent the intrusion of water vapor, but also avoid the recognition effect caused by the grabbing offset of the second polarizer 4 due to the groove 111. In detail, it is mainly through the opening of the groove 111 on the edge of the black matrix 11, so as to prevent water vapor from penetrating into the display area of the panel, causing corrosion or other adverse effects on the circuits, components, etc. in the display area; and then by staggering the opening position of the groove 111 with the second grabbing and identifying area 41, it can effectively avoid the subsequent misidentification of the grabbing and identifying of the second polarizer 4. After the groove 111 is opened, light will be directly transmitted through the groove 111, thereby forming a bright line on the black matrix 11. If this part of the bright line is not offset from the second grabbing and identifying area 41, then when the machine grabs and adjusts the position of the second polarizer 4, it may mistakenly identify the second grabbing and identifying area 41 on the second polarizer 4, instead of identifying the bright line part, resulting in mis-grasping or incorrect adjustment of the second polarizer 4, which in turn causes poor offset and even causes light leakage in the display panel.
[0047] It should be noted that the misidentification between the second grabbing and identifying area 41 and the bright line occurs because the machine mainly identifies the second polarizer 4 through the light at the edge of the second polarizer 4. If the second grabbing and identifying area 41 overlaps with the bright line or is too close to it, it may cause the machine to misidentify. In this embodiment, the second grabbing and identifying area 41 mainly includes the side reflective part of the second polarizer 4. The side reflective part of the second polarizer 4 shows brightness, thereby achieving grabbing and identifying.
[0048] Furthermore, a plurality of grooves 111 are provided and are spaced apart along the edge of the black matrix 11 , a plurality of second grabbing and identifying areas 41 are provided and are spaced apart along the edge of the second polarizer 4 , and along the edge of the black matrix 11 , the second grabbing and identifying areas 41 are located between two adjacent grooves 111 .
[0049] Furthermore, the second polarizer 4 is rectangular, four grooves 111 are provided, four second grabbing and identifying areas 41 are provided, the four grooves 111 are respectively provided at the four borders of the black matrix 11, the four second grabbing and identifying areas 41 are respectively located at the four corners of the second polarizer 4, along the four borders of the black matrix 11, two adjacent grooves 111 are spaced apart to define an identification avoidance area 1111, and every four second grabbing and identifying areas 41 are respectively located in the four identification avoidance areas 1111 in a one-to-one correspondence.
[0050] The relationship between the second polarizer 4, the second grabbing identification area 41 and the groove 111 is similar to the relationship between the first polarizer 2, the first grabbing identification area 21 and the groove 111. Therefore, the relationship between the second polarizer 4, the second grabbing identification area 41 and the groove 111 can be specifically seen in the derivation process of the relationship between the first polarizer 2, the first grabbing identification area 21 and the groove 111, which will not be repeated here.
[0051] In some embodiments, the groove 111 penetrates the black matrix 11 along the thickness direction of the black matrix 11, so that the depth of the groove 111 reaches the maximum, which is beneficial to improving the waterproof ability of the groove 111. In other embodiments, the groove 111 may not penetrate the black matrix 11 along the thickness direction of the black matrix 11, which is beneficial to improving the light shielding ability.
[0052] In some embodiments, the display panel includes a display area AA and a non-display area BB, the non-display area BB is arranged around the display area AA, the first polarizer 2 is located in the display area AA and extends to the non-display area BB, the first grabbing and identifying area 21 is located in the non-display area BB, and the groove 111 is located in the non-display area BB and is staggered with the first grabbing and identifying area 21. By limiting both the first grabbing and identifying area 21 and the groove 111 to the non-display area BB, the groove 111 and the grabbing and identifying area will not affect the display, and because they are located outside the display area AA, waterproof protection can be formed for the components and circuits in the display area AA.
[0053] In some embodiments, the side wall of the groove 111 is provided with a plurality of protrusions. By providing a plurality of protrusions, the area of the side wall of the groove 111 can be effectively increased, and the amount of water vapor that can be attached to the groove 111 can be increased, thereby enhancing the waterproof capability.
[0054] The embodiment of the present application further provides a display device, which includes a display panel as described in any of the above embodiments. Because the display device includes the display panel described in the above embodiments, it also has the structure and beneficial effects of the display panel. The derivation process of the specific structure and beneficial effects can be found in the above embodiments, which will not be repeated here.
