Solution Overview
Problem
Liquid crystal display devices with improved viewing angle characteristics and high light transmittance face a challenge as they require a large number of transistors and capacitors, which reduces transmittance.
Innovation Solution
A liquid crystal display panel is designed with distinct pixel regions for red, green, and blue colors, where the third pixel region has a higher number of transistors and a different light transmission range, allowing for varying gradations and improved visibility and viewing angles while maintaining high light transmittance.

Engineering Contradiction Analysis
1Adaptability or versatility
If a large number of transistors and capacitors are used to improve viewing angle characteristics through multiple domains, then viewing angle characteristics are improved, but light transmittance is reduced
Solution Approach 1:
The patent applies different numbers of transistors to different pixel regions based on their specific requirements. The blue pixel region (third pixel region) which has lower luminance is assigned three transistors to improve visibility, while the red and green pixel regions are assigned one transistor each, maintaining high light transmittance where it is less critical for visibility.
2Measurement precision
If the number of transistors in the blue pixel region is increased to improve visibility, then visibility is improved, but device complexity increases
Solution Approach 1:
The patent applies different numbers of transistors to different pixel regions based on their specific requirements. The blue pixel region (third pixel region) which has lower luminance is assigned three transistors to improve visibility, while the red and green pixel regions are assigned one transistor each, maintaining high light transmittance where it is less critical for visibility.
