Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquid crystal displays with high resolution face challenges in reducing power consumption and cost while maintaining luminance, as high backlight luminance requirements lead to increased power consumption and environmental impact, and color shift occurs at large view angles.
Innovation Solution
A display panel configuration with a mix of high and low domains, where the number of alignment regions differs between pixels, allowing for improved transmittance and reduced color shift at large view angles by configuring high domains to alleviate color shift and low domains to maintain aperture ratio, ensuring certain transmittance and customer experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If high backlight luminance is used to improve display luminance, then display luminance is improved, but power consumption increases
Solution Approach 1:
The patent applies local quality by differentiating pixel domains into high domain and low domain with different numbers of alignment regions. High domain pixels (e.g., blue pixels) have more alignment regions (8 regions) to improve view angle and reduce color shift, while low domain pixels (e.g., red and green pixels) have fewer alignment regions (4 regions) to maintain larger aperture ratio and higher transmittance. This localized differentiation optimizes overall display performance without requiring uniform high luminance across all pixels, thereby reducing total power consumption.
2Adaptability or versatility
If the number of alignment regions is increased to improve view angle, then color shift is reduced, but aperture ratio decreases
Solution Approach 1:
The patent implements local quality by assigning different domain configurations to different pixel types based on their specific requirements. Blue pixels, which are more sensitive to color shift, are configured as high domain with 8 alignment regions to ensure accurate color display at large view angles. Red and green pixels are configured as low domain with 4 alignment regions to maintain larger aperture ratio and higher transmittance. This selective application resolves the contradiction between view angle and aperture ratio.
Solution Approach 2:
The patent applies asymmetry by creating an asymmetric distribution of domain types across the pixel array. Instead of uniform domain configuration, the display panel uses a mixed configuration where approximately 1/3 of pixels (blue pixels) are high domain and 2/3 of pixels (red and green pixels) are low domain. This asymmetric arrangement optimizes the balance between color accuracy and light transmittance across the entire display.
