Title:
DISPLAY PANEL AND METHOD FOR MONITORING PRECISION OF PRINTED CIRCUIT OF DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2021/007940
Kind Code:
A1
Abstract:
Provided are a display panel and a method for monitoring the precision of a printed circuit of the display panel. The display panel comprises a color filter substrate (101, 201, 301), a thin-film transistor substrate (100, 200, 300), a metal pattern (102, 202, 203, 302), and a printed circuit (103, 204, 305); and the display panel further comprises an alignment scaleplate, wherein the alignment scaleplate comprises a plurality of alignment scales (403, 404) arranged in parallel. During monitoring, a main scale (403) and sub-scales (404) on the alignment scale plate are combined into a vernier caliper; and by means of the alignment of the metal pattern (102, 202, 203, 302) and the sub-scales (404), the printing precision is directly read from the sub-scales (404), and operation thereof is simple.
