Text Boundary Processing in Display Panels via Local RGB/BGR Swapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The irregular arrangement of sub-pixels in the text boundary area of display panels leads to unclear text boundary display, which existing technologies have not effectively addressed.
Innovation Solution
A method that involves determining whether a sub-pixel is a text boundary by comparing its grayscale value with adjacent sub-pixels and, if so, interchanging the grayscale values of red and blue sub-pixels in a sub-pixel group to enhance clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If sub-pixels are arranged in sequential order (RGB pattern) for general display areas, then the display structure is simple and manufacturing is easy, but text boundary areas show irregular patterns resulting in unclear text boundaries
Solution Approach 1:
The patent applies local quality by detecting text boundary areas and applying a specific sub-pixel arrangement (BGR pattern) only to those boundary regions, while maintaining the standard RGB sequential arrangement in non-boundary areas. This localized adjustment improves text boundary clarity without requiring complex reconfiguration of the entire display panel, thus resolving the contradiction between manufacturing simplicity and text boundary precision.
2Manufacturing precision
If the sub-pixel arrangement is changed to achieve clear text boundaries, then text boundary display quality improves, but the processing complexity and computational requirements increase
Solution Approach 1:
The patent implements preliminary action by pre-defining the BGR sub-pixel arrangement pattern for text boundary areas. The controller detects text boundary regions and pre-applies the corrected sub-pixel arrangement before final image rendering, avoiding complex real-time calculations during display operations. This reduces processing complexity while maintaining clear text boundary definition.
