Embodiment Construction

[0029] 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.

[0030] 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, active layer region and via holes of the TFT are shown in .

[0031] In order to avoid poor display caused by breakage in the corresponding area of ​​the TFT active layer when the flexible display device is bent, in this embodiment, the active layer area of ​​the TFT includes at least three via holes, and at least three via holes are not on the same straight line. On...

Abstract

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

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 corresponding regions of the active layers of thin-film transistors (TFTs) 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 1a and Fig...
