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 provided in this embodiment is mainly used in a flexible display device, including: gate lines, data lines, and several pixel units defined by intersections of gate lines and data lines, each of which includes at least one thin film transistor TFT. Figure 3-6 Only the source, gate, drain and via portions of the TFT are shown in .

[0029] In order to avoid poor display caused by breakage of the region corresponding to the drain of the TFT when the flexible display device is bent, in this embodiment, the drain region of the TFT includes at least three via holes, and at least three via holes are not on the same straight line. The drain of the thi...

Abstract

The invention relates to the display technical field and discloses an array substrate. The array substrate comprises grid lines, data lines and a plurality of pixel units; the pixel units are defined by the grid lines and the data lines in a cross mode; every pixel unit comprises at least one thin film transistor. The array substrate is characterized in that the drain electrode area of every thin film transistor at least comprises three via holes which are not located on the same straight line and a drain electrode of every thin film transistor is connected with an active layer of the thin film transistor through at least one via hole. According to the array substrate and a display device, the poor display caused by a fracture of the corresponding area of the drain electrode of the TFT (Thin Film Transistor) when the flexible display device is bent is effectively avoided.

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 bent, the drain of the thin film transistor is prone to breakage, and the source signal cannot be transmitted to the part connected to the drain through the drain. This breakage may eventually cause the voltage of the signal to fail to be transmitted to the pixel electrode, resulting in poor display. [0004...
