LCD Panel Pixel-Electrode Angles for Color Gamut Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
LCD products with low color gamut values, such as NTSC 45% and NTSC 60%, require high transmittance without reducing color richness.
Innovation Solution
Incorporating pixel electrodes with electrode lines inclined at different angles and a color filter with varying color gamut parts to enhance color richness without compromising transmittance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the color gamut is increased to enhance color richness, then the color gamut value is improved, but the transmittance is reduced
Solution Approach 1:
The color filter is divided into different regions with different color gamut characteristics. Specifically, a first region has a first color gamut value while a second region has a second color gamut value different from the first. This local differentiation allows certain areas to provide enhanced color richness while other areas maintain high transmittance, thereby resolving the contradiction between increasing color gamut and maintaining transmittance overall.
2Quantity of substance
If electrode lines are oriented at larger angles to improve color gamut, then the color gamut is enhanced, but the transmittance may be compromised
Solution Approach 1:
Different regions of the pixel electrode have different electrode line orientations. The first region has electrode lines at a first angle while the second region has electrode lines at a second angle. By locally optimizing the electrode line angles in different regions, the patent achieves improved color gamut in specific areas while maintaining acceptable transmittance characteristics, thus resolving the contradiction between color gamut enhancement and transmittance preservation.

AI summary
A liquid crystal display panel includes an array substrate and a color filter substrate. The array substrate includes scanning lines and a pixel electrode disposed on a first substrate, and the color filter substrate includes a color filter disposed on a second substrate. Each of the scanning lines extends in a first direction. The pixel electrode includes one or more first electrode lines each being at a first angle with the first direction and one or more second electrode lines each being at a second angle with the first direction, the first angle being greater than the second angle. The color filter includes a first part and a second part having a less color gamut value than the first part. The first part is disposed opposite to one of the first electrode lines, and the second part is disposed opposite to one of the second electrode lines.
