Mosaic area splicing method and system

Abstract

Provided is a display panel manufacturing method. A substrate is provided; the substrate is divided into a first zone and a second zone which are same in area; a photomask is provided and covers the first zone, and one side of the photomask is provided with a mosaic pattern, wherein the mosaic pattern is complementary with an original mosaic pattern after being turned at 180 degrees; photo masking is conducted on the first zone, wherein the mosaic pattern is formed on the side, close to the second zone, of the first zone; the photomask is turned at 180 degrees to conduct photo masking on the second zone, wherein the mosaic pattern is formed on the side, close to the first zone, of the second zone and combines with mosaics, close to the second zone, of the first zone, and accordingly a display panel is formed. Therefore, by utilizing the photomask splicing method, manufacturing of the display panel can be completed only by needing twice photo masking, the time is saved, and the efficiency is improved. The invention further provides a liquid crystal display.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a method and system for splicing mosaic regions. Background technique [0002] In the current panel design, the proportion of large-size products is gradually increasing. When the size of the manufactured panel exceeds the size of a photomask, photomask splicing is required. The biggest problem in splicing mask design is that the splicing between different masks is uneven, because there will be some differences in the film thickness of the junction area of ​​the two masks, and this difference is a sudden change. A clear dividing line can be seen when the panel is lit. After using the mosaic splicing design, this sudden difference can be converted into a gradient in the transition area, so that there is no obvious splicing unevenness. The traditional mosaic pattern is randomly generated by an algorithm. In actual production, the two mosaic areas are in a complementary f...

AI Technical Summary

Problems solved by technology

The traditional mosaic pattern is randomly generated by an algorithm. In actual production, the two mosaic areas are in a complementary form, and a complete figure is finally formed through two exposures. Using such a mosaic pattern design, it takes at least four times to make a panel Exposure, which has a relatively large impact on production capacity

In addition, when designing such a mosaic pattern, the algorithm is complicated, and the calculation of the mosaic area needs to be performed twice for two areas, which often takes a long time and is inefficient
