Abstract

The embodiment of the invention provides a substrate edge washing method, an edge washing device and a substrate. The substrate edge washing method comprises the following steps of: setting a corresponding identifier at the edge of a corresponding film layer of the substrate, detecting the identifier position in the edge washing process of an edge washing machine, and determining the edge washingamount of the substrate according to the distance between the identifier position and the identifier. According to the invention, the edge washing amount of the substrate is determined according to the distance between the identifier position and the identifier. Therefore, manual determination of the edge washing amount is avoided, the edge washing amount of the substrate can be determined more precisely, the substrate can be cleaned more precisely, and the cleaning efficiency is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a substrate edge cleaning method, an edge cleaning device and a substrate. Background technique [0002] Liquid crystal display (Liquid Crystal Display, LCD) is currently the most widely used display product in the market. Its production process technology is very mature, the product yield rate is high, the production cost is relatively low, and the market acceptance is high. The TFT-LCD (Thin Film Transistor-Liquid Crystal Display, Thin Film Transistor-Liquid Crystal Display) panel manufacturing industry has been developed for many years, and the production process of the product has been very refined and mature. [0003] In recent years, large-size liquid crystal displays have developed rapidly. In the preparation process, in addition to the necessary precision optical instrument exposure machine, it is also necessary to use an edge exposure machine for edge washing...
