Problems solved by technology

As mentioned above, the working electrode includes the gate electrode and the data electrode. Since the working signal received by the gate electrode and the data electrode is changing all the time, long-term work will lead to the accumulation of charges other than the working signal, that is, the extra charge, and the extra charge will accumulate more and more. If there are too many, it will break down the insulating layer between the working electrodes (such as the gate electrode insulating layer 2 or the data electrode insulating layer 3), causing a short circuit between adjacent working electrodes. If this short circuit occurs between the gate electrodes 11 of the array substrate If it occurs between the data electrodes 12 of the array substrate, there will be a defect in the vertical signal line.
The signal line defect of the liquid crystal display caused by the short circuit between the working electrodes is a progressive defect, and the quality dependence test cannot be controlled, so that the liquid crystal display with potential quality problems is easy to flow into the market

Abstract

The invention provides an array substrate and a display device. The array substrate comprises a plurality of working electrodes arranged at intervals, the working electrodes are used for introducing working signals, the array substrate further comprises guard electrodes, the guard electrodes and the working electrodes are arranged in a same layer and adjacent to one another, and the guard electrodes are used for dredging extra charges accumulated on the working electrodes. According to the array substrate, the extra charges accumulated on the working electrodes are dredged through the guard electrodes, short circuit among the working electrodes is avoided, so that the quality of the array substrate is ensured, and the quality of the display device is also ensured.

Description

technical field [0001] The present invention belongs to the field of display technology, and in particular, relates to an array substrate and a display device. Background technique [0002] Liquid Crystal Display (LCD: Liquid Crystal Display) has become the mainstream product in the current flat panel display due to its small size, low power consumption, and no radiation. Array substrate is an important part of liquid crystal display and also a key component for display. [0003] Usually, the signal input of the array substrate is introduced by an external connection system of a printed circuit board (PCB, Printed Circuit Board). The printed circuit board is arranged on the periphery of the array substrate, and the printed circuit board is provided with a working signal driving chip. The working signal driving chip sends a driving signal, and the driving signal is transmitted to the working signal input terminal of the array substrate, thereby controlling the display of the...
