Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing liquid crystal processing technologies, the UV curing of sealants can be hindered by the need for transparent regions on array substrates, which are typically achieved by making the wiring regions partially transparent, but this can compromise the conductivity of the wires.
Innovation Solution
The array substrate design features a transparent conductive strip and wire layers in direct contact, with exposure holes in the wire layer to allow UV curing while maintaining conductivity through connected conductive blocks, ensuring reduced resistance and improved conductivity.

1Reliability
If a mask is used to shield the liquid crystal region during UV curing, then the liquid crystal is protected from pollution, but the manufacturing process becomes more complex
Solution Approach 1:
The masking function is extracted from the UV curing process and integrated into the wire structure itself. The upper wire layer with exposure holes serves as both a conductive element and a UV filter, eliminating the need for separate masks during the curing process.
Solution Approach 2:
The wire structure performs multiple functions: it provides electrical conductivity through the lower wire layer and conductive portions, while simultaneously serving as a UV filter through the upper wire layer with exposure holes. This multi-functionality eliminates the need for separate masking components.

Function Achieved in This Case
This design enables effective UV curing of sealants without compromising the conductivity of the wires, facilitating efficient manufacturing and performance in display devices.
Implementation Method 1
a UV curing manner is commonly adopted in the industry to prevent pollution caused to the liquid crystal when the liquid crystal is in direct contact with the sealant. The so-called UV curing (ultraviolet curing) is mainly to shield a liquid crystal region
Implementation Method 2
the transparent conductive strip and the wire are located in different layers and are in direct contact with each other, and the wire has one or more exposure holes formed therein
