Embodiment Construction

[0038] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] refer to figure 1 , figure 1 It is a schematic flowchart of an embodiment of the short circuit detection method of the present invention. The short circuit detection method provided in this embodiment includes the following steps:

[0040] Step S10, transferring an array substrate circuit by an exposure transfer method to form a transferred circuit;

[0041] In this embodiment, a layer of photoconductive layer can be evenly coated on a flat plate, and then the circuit of the array substrate is transferred onto the flat plate by an exposure transfer method. Specifically, during the exposure process, the part of the photoconductive layer on the flat panel that is illuminated will form a conductive line, and the part that is not illuminated will form a blank area. combined reference figure 2 and image 3 as...

Abstract

The invention discloses a detection method and a device for a short circuit. The detection method for the short circuit comprises the following steps: carrying out transfer printing on an array substrate line through an exposure transfer printing method to form a transfer-printed line; detecting a position of an open circuit in the transfer-printed line; and analyzing a position of the short circuit of the array substrate line according to the position of the open circuit. According to the method, detection on the short circuit in the substrate line is converted to detection on the open circuit, so that difficulty of the detection on the short circuit in the array substrate line is reduced, and production efficiency is improved.

Description
