Abstract

The invention discloses a coding method, a coding device and a coding system. The coding method comprises the following steps: when a substrate is conveyed to an exposure machine, adjusting the substrate so as to align an exposure alignment mark on the substrate with the exposure machine; controlling the exposure machine to form a coding area on the adjusted substrate; when the substrate on whichthe coding area is formed is conveyed to a coding machine, adjusting the substrate so as to align the exposure alignment mark on the substrate with the coding machine; controlling the coding machine to form an identification code on the coding area on the adjusted substrate. The coding machine and the exposure machine use the same alignment mark, so that the coding precision of the coding machineis improved, and the identification code is avoided from deviating from the coding area to affect the normal use of the identification code.

Description

technical field [0001] The present application relates to the technical field of display panels, and in particular to a coding method, a coding device and a coding system. Background technique [0002] In recent years, small and medium-sized TFT-LCD (Thin Film Transistor Liquid Crystal Display, TFT-LCD for short) and OLED (Organic Light Emitting Diode, organic light-emitting diode display, OLED for short) have developed rapidly. In order to improve product yield And conduct follow-up investigations on defective products. Each display panel has a unique identification code, and the glass substrate that makes the display panel also has a unique identification code. All glass substrates need to carry out this identification. Among them, on the basis of using a precision optical instrument exposure machine, a coding machine is also required. The coding accuracy is determined by both the exposure accuracy and the coding accuracy. [0003] The identification code on the glass sub...
