Liquid Crystal Display Subpixel Data Line Segmentation for Moire Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid crystal display devices for three-dimensional image display face issues such as insufficient signal writing, moire, and increased circuit size, which affect image quality and cost, particularly when attempting to combine methods for reducing these problems.
Innovation Solution
A liquid crystal display device with a matrix arrangement of pixels and subpixels, where each subpixel is driven by a gate line and a data line, and has a color resist transmitting light of the same color as adjacent subpixels, with a nearly constant ratio of opening to shielding part width, and multiple data lines dividing the subpixels to prevent moire and ensure sufficient aperture rate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple data lines are provided for each column of subpixels to reduce moire, then image quality is improved, but circuit complexity and cost increase
Solution Approach 1:
The patent divides each subpixel into multiple regions using multiple data lines (at least three data lines per column of subpixels), which segment the subpixel structure to prevent moire patterns while maintaining manageable circuit complexity through systematic arrangement
Solution Approach 2:
The patent applies different data line configurations to different regions of the display panel, with multiple data lines specifically arranged within subpixel columns where moire is problematic, while other areas maintain standard configurations, optimizing resource distribution
2Manufacturing precision
If the aperture rate is increased to improve image quality, then light transmission is improved, but circuit layout becomes more difficult
Solution Approach 1:
The patent optimizes the width ratios of openings and shielding parts within subpixels to maintain a nearly constant ratio across different positions, which maximizes aperture rate while accommodating multiple data lines through careful parameter adjustment
Solution Approach 2:
The patent arranges multiple data lines in the vertical direction (second direction) extending through subpixels, utilizing the vertical dimension to provide sufficient signal writing time while maintaining horizontal aperture rate, effectively moving the solution from a horizontal to vertical arrangement
3Manufacturing precision
If signal writing time is increased to ensure sufficient writing, then image quality is improved, but frame rate decreases
Solution Approach 1:
The patent segments the display refresh process by providing multiple data lines that can be driven in parallel, dividing the signal writing task across multiple channels to reduce the time required per channel while maintaining overall writing sufficiency
Solution Approach 2:
The patent ensures continuous signal writing across multiple data lines simultaneously, allowing the display to maintain high frame rates while each subpixel receives sufficient writing time through parallel operation of multiple data lines

AI summary
Red, green, and blue color resists and a shielding layer (black matrix) are layered on a liquid crystal panel. The subpixels are zoned by the shielding layer. The subpixels arranged in three rows and two columns form a pixel. The red, green, and blue color resists are colored on the basis of a row of subpixels. The color resists extend in stripes in the X-axis direction. Three data lines are provided for each column of subpixels in the manner that one is provide under the shielding layer and the other two diagonally divide the opening of the shielding layer at equal intervals.
