Description

Technical Field

[0001] The utility model relates to display technology, in particular to an array substrate and a liquid crystal panel. Background Art

[0002] The liquid crystal panel mainly includes a color filter substrate, an array substrate, and a liquid crystal material filled between the color filter substrate and the array substrate. The color filter substrate and the array substrate are relatively bonded with UV glue, and the UV glue seals the liquid crystal material between the color filter substrate and the array substrate. After the color filter substrate and the array substrate are relatively bonded, the UV glue needs to be cured with UV light. However, the color filter substrate cannot transmit light due to the BM black matrix, so the UV light needs to be cured from the side of the array substrate.

[0003] like Figure 1 As shown, the array substrate includes a display area 100 and a non-display area 200 outside the display area 100, and the array substrate is slightly larger than the color filter substrate. The portion of the non-display area 200 that exceeds the color filter substrate is mainly used to provide a binding space for the source driver chip 240. The non-display area 200 is provided with a GOA circuit 210 on the left and right sides of the display area 100, and a gate signal line 220 is provided between the GOA circuit 210 and the display area 100, which is used for the GOA circuit 210 to output a gate signal to the pixels in the display area 100; and a control signal line 230 is provided between the GOA circuit 210 and the source driver chip 240, which is used for the source driver chip 240 to output a control signal to the GOA circuit 210; the gate signal and control signal lines 230 are connected to the GOA circuit 210 from the left and right sides of the GOA circuit 210, respectively.

[0004] In some LCD panels, such as Figure 2 As shown, in order to improve the bonding force between the color filter substrate and the array substrate and to protect the GOA circuit 210, the coating range of the UV sealant 6 will cover the GOA circuit 210 and extend all the way to the edge of the substrate of the color filter substrate; and the control signal wiring 230 is a metal wiring, which will reflect UV light and thus affect the light curing effect of the UV sealant 6, so that the bonding and sealing effect of the UV sealant 6 is reduced.
