Abstract

The invention provides an array substrate, a detection circuit and a method for detecting open circuit and short circuit of the array substrate. The detection circuit comprises a plurality of first switch tubes, a plurality of second switch tubes, a plurality of first devices, first to sixth input ends, a first output end and a second output end, wherein a first level signal is input to the first input end, the second input end, the fifth input end and the sixth input end, and a second level signal is input to the third input end and the fourth input end, thus whether wires are open circuit can be determined; the first level signal is input to the second input end, the fourth input end and the fifth input end, and the second level signal is input to the first input end, whether the signal output by the first output end is the second level signal is detected to determine whether the wires are short circuit. By adopting the detection circuit, the short circuit or open circuit of the wires on the array substrate is avoided so as not to influence normal display of a display device.

Description

technical field [0001] The present invention relates to the technical field of display devices, and more specifically, to an array substrate, a detection circuit, and a detection method for open circuit and short circuit. Background technique [0002] In the prior art, multiple array units are fabricated on the same substrate at the same time, and then the array units are cut after fabrication to form individual array substrates. Afterwards, the array substrate and the electronic paper film are pasted together to form an electronic paper display device. However, in the process of cutting and transporting the array substrate, it is easy to scratch the traces on the array substrate, such as gate lines and data lines, etc., resulting in disconnection or short circuit of the traces, which affects the normal display of the display device. . Contents of the invention [0003] In view of this, the present invention provides an array substrate, a detection circuit and an open ci...
