Display Panel Driving Circuit for Transparent and Non-Transparent Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels with both transparent and non-transparent areas face challenges in driving pixels effectively, particularly due to differences in pixel arrangements, which affect display resolution and quality.
Innovation Solution
A method and apparatus that determine and process distinct types of picture data for non-transparent and transparent display areas, with sub-pixel rendering operations to enhance display resolution and quality, including the use of a determining circuit, processing circuit, and driving circuit to manage pixel data for each area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If sub-pixel rendering operation is performed on picture data for non-transparent display area, then display resolution and quality are improved, but computational complexity increases
Solution Approach 1:
The picture data is segmented into different types based on display area (transparent vs. non-transparent). Sub-pixel rendering is selectively applied only to the first type of picture data for non-transparent areas, while the second type for transparent areas is processed differently. This segmentation resolves the contradiction by applying computational processing only where needed, improving display resolution in non-transparent areas without unnecessarily increasing computational complexity for the entire frame.
2Manufacturing precision
If distinct picture data processing is applied to transparent and non-transparent areas, then display quality is improved, but processing time increases
Solution Approach 1:
Different processing methods are applied to different regions of the display panel. The non-transparent display area receives sub-pixel rendering processing to enhance quality, while the transparent display area uses a different processing approach. This local quality principle resolves the contradiction by optimizing processing for each specific area's requirements, improving overall display quality without uniformly increasing processing time across the entire panel.
