Display Panel Light Shielding Parts Moire Pattern Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquid Crystal Display (LCD) panels suffer from low light transmittance due to moire patterns caused by mismatched conductive layer patterns between the liquid crystal display panel and the light control panel, resulting in a subpar display effect.
Innovation Solution
The display panel design includes a first array substrate and a first opposite substrate with a liquid crystal layer in between, featuring driving transistors and light shielding parts arranged in an array to improve light transmittance by reducing the area of light shielding regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conductive layers of liquid crystal display panel and light control panel are arranged with different patterns to reduce moire patterns, then moire patterns are reduced, but light transmittance decreases
Solution Approach 1:
The patent extracts the light shielding function from the conductive layer pattern and concentrates it into dedicated light shielding parts. By removing unnecessary light shielding areas and keeping only essential shielding regions, the patent reduces moire patterns while preserving necessary light control, thereby improving overall light transmittance without compromising moire pattern reduction
Solution Approach 2:
The patent applies light shielding selectively only where needed - specifically in light shielding parts corresponding to driving transistors - rather than using uniform patterns across the entire panel. This localized approach allows conductive layers to have different patterns in different regions, reducing moire patterns while maintaining high light transmittance in pixel regions
2Object-affected harmful factors
If light shielding regions are increased to improve contrast, then contrast is improved, but light transmittance decreases
Solution Approach 1:
The patent optimizes the parameters of light shielding parts, specifically their size and position, to achieve the minimum necessary shielding area. By carefully controlling the dimensions and placement of light shielding parts corresponding to driving transistors, the patent improves display contrast while minimizing the impact on light transmittance
