Problems solved by technology

If the display is bent, the active layer 110, the source 120 or the drain 130 of the TFT along the dotted line is broken, which will cause the channel to be unable to transmit carriers, that is, the source and drain of the TFT cannot be turned on, and the corresponding pixel unit doesn't work so that it shows badly

Embodiment Construction

[0027] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] The array substrate of this embodiment includes: a gate line, a data line, and several pixel units defined by intersections of the gate line and the data line, and each of the pixel units includes at least one thin film transistor. In order to reduce the possibility of TFT breakage when the flexible display device is bent, at least one pattern of the active layer and the drain electrode of the thin film transistor is a pattern of an anti-crack structure. The pattern of the anti-fracture structure can partially disperse the tension when the flexible display device is bent, thereby reducing the probability of TFT fracture when the flexible display device is bent, and ...

Abstract

The invention relates to the technical field of display, and discloses an array substrate. The array substrate comprises grid lines, data lines and a plurality of pixel units defined by intersecting the grid lines and the data lines. Each pixel unit comprises at least one TFT, and a graph of at least one of an active layer and a drain electrode of each TFT is of a fracture-prevention structure. According to the array substrate, as the graphs of the active layers or the drain electrodes and the like of the TFTs are manufactured to be of the fracture-prevention structures, when a flexible display device is bent, part of tension can be dispersed, the fracture probability of the TFTs when the flexible display device is bent is lowered, and it is guaranteed that the flexible display device can normally carry out display.

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, the active layer, source and drain corresponding regions of thin film transistors (TFT) are prone to breakage when bent. 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 1 A...
