Solution Overview
Problem
High-resolution liquid crystal display devices face issues with electric field interference between adjacent pixel electrodes, leading to phenomena such as color mixing and light leakage due to the close proximity of pixel units, which affects the display quality.
Innovation Solution
An array substrate design featuring a protrusion between adjacent pixel electrodes, with a portion of the first insulating layer extending into the overlapping region of adjacent color filter units, effectively isolating the electric field and reducing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the pixel unit size is reduced to increase resolution, then the number of pixel units per inch increases, but the electric field interference between adjacent pixel electrodes worsens
Solution Approach 1:
The invention introduces a protrusion structure that divides the space between adjacent pixel electrodes into isolated regions. This segmentation prevents the electric field from one pixel electrode from interfering with adjacent pixel electrodes, thereby resolving the interference issue while maintaining high resolution
Solution Approach 2:
The protrusion acts as an intermediary structure between adjacent pixel electrodes. It physically separates the electric fields of neighboring pixels, serving as a barrier that prevents harmful electric field interference while allowing the pixel units to remain closely spaced for high resolution
2Measurement precision
If the distance between pixel electrodes is reduced to increase resolution, then more pixel units fit per inch, but phenomena such as color mixing and light leakage occur
Solution Approach 1:
The protrusion segments the liquid crystal layer into isolated regions above each pixel electrode. This segmentation prevents liquid crystal molecules from being affected by adjacent pixel electrodes' electric fields, thereby eliminating color mixing and light leakage while maintaining small pixel unit sizes
Solution Approach 2:
The invention extracts the harmful electric field interference from the system by introducing the protrusion structure. This removes the source of color mixing and light leakage, allowing high resolution to be achieved without these detrimental effects
