Display Panel Data Line Segmentation for Uniform RGB Luminance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display technologies, the continuous voltage jumps in data signal lines between sub-pixels of different colors lead to signal distortion and uneven luminance, affecting display quality and uniformity, especially during aging tests.
Innovation Solution
Each sub-pixel column has separate data signal lines for red, green, and blue sub-pixels, ensuring that data signals are transmitted accurately in a time-division manner without voltage jumps, maintaining consistent light emitting and aging degrees across the display panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If blue sub-pixels and red/green sub-pixels share one data signal line, then the number of data signal lines is reduced, but voltage jumps occur causing signal distortion and affecting display quality
Solution Approach 1:
The patent segments the data signal lines by color, creating separate data signal lines for blue sub-pixels and red/green sub-pixels. This segmentation prevents voltage jumps that would occur when different color sub-pixels share a common data signal line, thereby maintaining signal transmission accuracy while managing the overall number of signal lines through organized grouping.
2Adaptability or versatility
If data signals jump continuously to satisfy different luminance requirements, then both blue and red/green sub-pixel luminance requirements are met, but signal loss increases and data signals become distorted
Solution Approach 1:
By segmenting data signal lines according to sub-pixel color, the patent eliminates the need for continuous voltage jumps on shared signal lines. Each color group receives dedicated signal lines that maintain stable voltage levels, preventing signal distortion and information loss while still satisfying the different luminance requirements of various sub-pixel colors through dedicated signal paths.
