LCD Panel Pixel Electrode Thickness Variation for Wide Viewing Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional LCD panels suffer from low light transmittance and unstable liquid crystal tilting, which hinder the achievement of a wide visual angle display due to the chaotic tilt directions of liquid crystal molecules near connection patterns.
Innovation Solution
The LCD panel design incorporates pixel electrodes with varying color resistance thicknesses, including main, sub-pixel, first transitional, and second transitional areas, along with a TFT and storage capacitor, where the first transitional area is between the main and sub-pixel areas, and the second transitional area is adjacent to through holes, allowing for different driving efficiencies and improved light transmittance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connection pattern is used to electrically connect the pixel electrode to the active component, then electrical connection is achieved, but the liquid crystal molecules near the connection pattern tilt in chaotic directions, reducing light transmittance
Solution Approach 1:
The pixel electrode is divided into different areas with different color resistance thicknesses: the first area (near connection pattern) has greater thickness than the second area (main display area). This local variation in thickness creates different driving efficiencies in different regions, allowing the connection area to stabilize liquid crystal tilt directions while maintaining good light transmittance in the main display area.
2Ease of manufacture
If the pixel electrode has uniform thickness, then manufacturing is simplified, but different areas cannot achieve different driving efficiencies needed for wide visual angle display
Solution Approach 1:
The pixel electrode employs local quality variation through different color resistance thicknesses in different areas. The first area has greater thickness to provide stable driving efficiency near the connection pattern, while the second area has lesser thickness for optimal light transmittance in the main display region, achieving both manufacturing feasibility and functional adaptability.
3Adaptability or versatility
If liquid crystal molecules tilt in chaotic directions, then the display can accommodate various viewing angles, but light transmittance decreases and displaying effect deteriorates
Solution Approach 1:
The invention changes the physical parameter of color resistance thickness in different areas of the pixel electrode. By making the first area (near connection pattern) have greater thickness than the second area, it creates different driving efficiencies that control liquid crystal tilt angles, stabilizing them in desired directions while maintaining wide viewing angle capability and good light transmittance.
