Problems solved by technology

If the display is bent, the grid line 120 or the data line 141 and the signal line 142 are broken along the dotted line, which will cause the pixel units after the break to not work normally, so that the display is poor

Embodiment Construction

[0028] The array substrate of this embodiment includes structures such as gate lines, gate insulating layers, and data lines formed on the base substrate. gate type TFT) fracture probability, a number of first concave-convex structures are formed on the surface of the gate insulating layer away from the base substrate, so that the gate lines or data lines formed on the gate insulating layer also form a number of first concave-convex structures correspondingly structure, the first concavo-convex structure has the effect of dispersing tension, so that the grid lines or data lines are not easy to break.

[0029] specifically, Figure 2a with 2b As shown, the OLED array substrate is taken as an example, and the thin film transistor is a bottom-gate type, including gate lines 220, gate insulating layer 230, data lines 241, power signal lines 242, and passivation layer 250 formed on the base substrate 210 in sequence. , the resin layer 260 , the anode 270 and the pixel definition ...

Abstract

The invention relates to the technical field of displaying and discloses an array substrate which comprises a grid line formed on an underlay substrate, a grid insulating layer and a data line. A plurality of first concave-convex structures are formed on the surface, away from the underlay substrate, of the grid insulating layer. The invention further discloses a display device comprising the array substrate. By enabling the surface of the grid insulating layer to form a graph of a concave-convex structure, the grid or the data line formed on the surface of the grid insulating layer is enabled to form a graph of a concave-convex structure, and the graph of the concave-convex structure can enable a tension portion to be dispersed when a flexible display device bends, so that breaking probability of the grid line or the data line when the flexible display device bends is reduced, and the flexible display device is ensured to be capable of normally displaying.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate and a display device. Background technique [0002] Flexible display devices Compared with ordinary rigid displays, flexible displays have many advantages: impact resistance and stronger shock resistance; light weight, small size; more convenient to carry; using a tape-and-roll process similar to newspaper printing process, the cost is lower Wait. At present, the main flexible display devices mainly include: flexible OLED displays and flexible liquid crystal displays. [0003] For flexible OLED displays and flexible liquid crystal displays, when bending, the areas corresponding to the gate lines and data lines are prone to breakage. Such breakage may cause the voltage of the signal to fail to be transmitted to the pixel electrode, resulting in poor display. [0004] Take 2T1C OLED display as an example, such as Figure 1a with 1b As shown, a pixel ...
