Color Filter Substrate Groove Structure Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In liquid crystal display (LCD) technology, the color blocking pattern in the color filter often peels, leading to white highlights and reduced product quality due to insufficient contact area with the substrate.
Innovation Solution
A color film substrate with a translucent pattern featuring a groove structure that increases contact area between the color blocking pattern and the substrate, incorporating a black matrix pattern and a transparent conductive layer to enhance adhesion and prevent peeling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the color blocking pattern is formed on a flat translucent pattern, then the manufacturing process is simple, but the contact area is insufficient causing peeling
Solution Approach 1:
The translucent pattern is transformed from a flat two-dimensional structure to a three-dimensional structure with groove structures. This dimensional change increases the contact area between the color blocking pattern and the translucent pattern, preventing peeling while maintaining manufacturing feasibility through standard photolithography and etching processes
Solution Approach 2:
The translucent pattern is designed with groove structures that create a porous-like surface topology. This increased surface area provides better mechanical interlocking and adhesion for the color blocking pattern, solving the peeling problem without requiring additional adhesive layers or complex assembly steps
2Reliability
If the contact area between color blocking pattern and substrate is increased, then peeling is prevented, but the manufacturing process becomes more complex
Solution Approach 1:
The groove structures are pre-formed in the translucent pattern before the color blocking pattern is deposited. This preliminary action ensures that when the color blocking pattern is subsequently formed, it automatically achieves increased contact area and better adhesion without requiring additional manufacturing steps or post-processing operations

AI summary
The present disclosure discloses a color film substrate and a manufacturing method thereof, increase a translucent pattern with one layer has groove structure between the substrate and the color blocking pattern, and increase the contact area between the color blocking pattern and the translucent pattern through the groove structure, by means of the contact of the translucent pattern and the substrate, thereby increasing the contact area between the color blocking pattern and the substrate, it is possible to avoid the color blocking pattern peeling, to improve the quality of the product.
