Problems solved by technology

[0005] Since the surface of the flat layer 54 is relatively flat, the bonding strength after bonding with the frame sealant 3 is very low, which can easily lead to poor peeling during the reliability test, seriously affecting product quality.

Embodiment 1

[0027] This embodiment provides a display substrate, such as figure 2 and image 3 As shown, it includes a display area 1 and a non-display area 2. The display substrate can be boxed with the second substrate 4 through the sealant 3 arranged in the non-display area 2, and also includes a concave-convex film layer arranged in the non-display area 2. 5. The concave-convex film layer 5 has an uneven surface. The concave-convex film layer 5 is located on the side facing the box of the display substrate and corresponds to the setting position of the sealing glue 3. The concave-convex film layer 5 is used to match the sealing glue 3 and fit.

[0028] Since the concave-convex film layer 5 has an uneven surface, and the frame sealant 3 is in a soft and plastic state before curing, in the process of bonding the frame sealant 3 and the concave-convex film layer 5, the frame sealant 3 is pressed against each other. Under pressure, the shape of the bonding surface can be molded to matc...

Embodiment 2

[0039] This embodiment provides a display substrate, which is different from Embodiment 1 in that Figure 4 As shown, some of the red pixels 51 , green pixels 52 and / or blue pixels 53 are connected as a whole and spliced ​​with each other to form the interval region 9 .

[0040] Such setting can also greatly increase the contact area between the frame sealant and the concave-convex film layer, thereby greatly enhancing the bonding strength between the two.

[0041] Other structures of the display substrate in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

Embodiment 3

[0043] This embodiment provides a display substrate. The difference from Embodiment 1-2 is that the concave-convex film layer does not include a flat layer, that is, no flat layer is provided on the display substrate; or, as Figure 5 As shown, the planar layer 54 is only provided in the display area 1 , but does not extend to the non-display area 2 .

[0044]In this way, the contact area between the frame sealant 3 and the concave-convex film layer 5 can also be increased, thereby greatly enhancing the bonding strength between the two.

[0045] Other structures of the display substrate in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

[0046] Beneficial effects of Embodiment 1-3: In the display substrate in Embodiment 1-3, the contact area between the sealant and the display substrate is increased by arranging a concave-convex film layer in the area corresponding to the position of the sealant. , thereby improving the bonding strength ...

Abstract

The invention provides a display substrate, a display panel and a display device. The display substrate includes a display area and a non-display area. The display substrate can be boxed with the second substrate through the sealant correspondingly arranged in the non-display area, and also includes a concave-convex film layer arranged in the non-display area. The concave-convex film layer has For the uneven surface, the concave-convex film layer is located on the box-facing side of the display substrate and corresponds to the setting position of the sealant, and the concave-convex film layer is used to fit and adhere to the frame sealant. The display substrate increases the contact area between the frame sealant and the display substrate by setting a concave-convex film layer in the area corresponding to the position where the frame sealant is installed, thereby improving the bonding strength between the frame sealant and the display substrate. . The display panel can greatly improve the manufacturing quality of the display panel by using the above display substrate, thereby improving the quality of the display panel. The display device can improve the quality of the display device by using the above display panel.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display substrate, a display panel and a display device. Background technique [0002] A liquid crystal display is composed of an array substrate, a color filter substrate, and a liquid crystal sandwiched between the two substrates. Usually, the array substrate and the color filter substrate need to be bonded and sealed with peripheral sealing glue after they are boxed together. [0003] With the needs of market development, display products with thinner and narrower frames are more and more favored by the market. With the narrowing of the frame of the liquid crystal display, the requirements for the manufacturing process and materials of the liquid crystal display are also getting higher and higher. [0004] As the frame becomes narrower and narrower, the width of the sealant is also gradually narrowed. Such as figure 1 As shown, at present, the color filter substr...
