Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current liquid crystal display technologies face challenges in reducing chromatic aberration and improving imaging quality, particularly in maintaining high transmittance and wide viewing angles while minimizing manufacturing costs.
Innovation Solution
The introduction of a pixel structure with four domain regions, where each pixel region includes a first, second, third, and fourth domain display region, with specific angles between the strip-shaped pixel electrodes and a reference direction, allowing for symmetrical liquid crystal molecule alignment and reduced differences in driving voltage, thereby minimizing chromatic aberration and enhancing viewing angles.

Engineering Contradiction Analysis
1Illumination intensity
If double-domain ADSDS technology is used, then viewing angle is improved, but chromatic aberration increases
Solution Approach 1:
The pixel region is divided into four distinct domain regions instead of two, with each region having pixel electrodes oriented at different angles. This segmentation allows different viewing angle characteristics to be distributed across regions while compensating for chromatic aberration through the combined effect of all four domains
Solution Approach 2:
The four domain regions are configured with asymmetric angle relationships relative to the reference direction, where adjacent regions have different orientation angles. This asymmetric arrangement creates balanced optical paths that compensate for wavelength-dependent phase differences, reducing chromatic aberration while maintaining wide viewing angles
2Illumination intensity
If pixel electrodes are oriented at different angles in different regions, then viewing angle is improved, but manufacturing complexity increases
Solution Approach 1:
The pixel region is divided into four distinct domain regions instead of two, with each region having pixel electrodes oriented at different angles. This segmentation allows different viewing angle characteristics to be distributed across regions while compensating for chromatic aberration through the combined effect of all four domains
Solution Approach 2:
The orientation angles of pixel electrodes are systematically varied across the four domain regions according to specific angular relationships. By controlling the angular parameters of the strip-shaped pixel electrodes relative to the reference direction, the invention achieves wide viewing angles and chromatic aberration reduction through precise geometric configuration

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration effectively reduces chromatic aberration and improves imaging quality by aligning liquid crystals uniformly across regions, maintaining high transmittance and wide viewing angles without increasing manufacturing costs.
Implementation Method 1
each pixel region is divided into: a first domain display region, a second domain display region, a third domain display region, and a fourth domain display region. A strip-shaped pixel electrode in the first domain display region forms a first angle with a reference direction, a strip-shaped pixel electrode in the second domain display region forms a second angle with the reference direction, a strip-shaped pixel electrode in the third domain display region forms a third angle with the reference direction, and a strip-shaped pixel electrode in the fourth domain display region forms a fourth angle with the reference direction
