LTPS Display Panel Matrix Electrode Color Washout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Low Temperature Poly Silicon (LTPS) display panels suffer from large view angle color washout due to light interference between adjacent pixels, degrading display quality when viewed from angles.
Innovation Solution
A matrix electrode is positioned on the color film substrate close to the liquid crystal layer and coupled to the common electrode signal, eliminating voltage differences and maintaining the liquid crystal layer in an opaque state, thus preventing light interference between pixels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional LTPS display panel structure is used, then high resolution and fast response speed are achieved, but large view angle color washout occurs due to light interference between adjacent pixels
Solution Approach 1:
A matrix electrode is introduced as an intermediary element between the color filter substrate and the liquid crystal layer. This matrix electrode, positioned corresponding to the black matrix regions, acts as a mediator to control light passage and eliminate interference between adjacent pixels, thereby solving the color washout problem while preserving high resolution display capabilities
2Object-affected harmful factors
If the matrix electrode is positioned close to the liquid crystal layer on the color film substrate, then light interference between adjacent pixels is eliminated, but the device structure becomes more complex
Solution Approach 1:
The matrix electrode is merged with the existing color film substrate structure, utilizing the same substrate and positioning system. By combining the matrix electrode formation with the existing color filter and black matrix fabrication processes, the patent eliminates light interference without requiring separate complex assembly steps or additional structural layers

AI summary
The present invention provides a display panel and a manufacture method thereof. By locating the matrix electrode corresponding to the black matrix on one side of the color film substrate, which is close to the liquid crystal layer, and because the matrix electrode is coupled to the common electrode signal, no voltage difference exists between the matrix electrode and the common electrode, and no matter in condition of being electrified or not electrified, the liquid crystal layer between the matrix electrode and the common electrode of the array substrate is not orientated and constantly appears in an opaque state so that no interference generates to light between adjacent pixels of the panel to eliminate the large view angle color washout of the panel and to improve the display quality of the LTPS display panel.
