Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-resolution array substrates face issues with electric field interference between adjacent electrodes, leading to light leakage and color mixing, compromising display quality due to the decreasing size of pixel regions and increasing resolution.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the resolution of the array substrate is increased, then the pixel density is improved, but the distance between adjacent electrodes decreases causing electric field interference
Solution Approach 1:
An insulation element is introduced as an intermediary between adjacent transparent electrodes. This insulation element extends in the thickness direction of the substrate and is positioned between the electrodes to block electric field lines, preventing interference while allowing the electrodes to maintain reduced spacing for high resolution display
2Area of stationary object
If the distance between adjacent electrodes is reduced to maintain aperture ratio, then the electrode spacing is improved, but electric field interference increases causing light leakage and color mixing
Solution Approach 1:
The insulation element serves as a mediator that extends vertically between adjacent electrodes, blocking electric field lines that would otherwise cause light leakage and color mixing. This allows electrodes to be positioned closer together while maintaining aperture ratio, preventing harmful electromagnetic interference
Solution Approach 2:
The insulation element extends in the thickness direction (vertical dimension) of the substrate, creating a three-dimensional barrier between electrodes. By utilizing the vertical dimension rather than only horizontal spacing, the solution blocks electric field interference without sacrificing aperture ratio or requiring larger pixel regions
