Delta RGBW Sub-pixel Rendering for Color Bleeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sub-pixel rendering algorithms for Delta RGBW panels suffer from color bleeding, jaggy issues in vertical gray lines, and shift flickers due to sub-pixel G and W rendering with different weightings, leading to poor text performance and disconnection of one pixel width slash lines.
Innovation Solution
A sub-pixel rendering method that classifies sub-pixels into three types and renders them using specific pixel combinations, such as left and right pixels, to ensure consistent weighting and prevent color bleeding and jaggy issues, utilizing a controller to apply appropriate pixel data to output sub-pixels.

1Illumination intensity
If conventional sub-pixel rendering algorithm is used for Delta RGBW panel, then brightness is improved by adding sub-pixel W, but color bleeding and jaggy issues occur due to different weighting of sub-pixels G and W
Solution Approach 1:
The invention segments the rendering process by classifying sub-pixels into three distinct types (first type: R and B sub-pixels, second type: G sub-pixel, third type: W sub-pixel) and applying different rendering algorithms to each type. This segmentation allows each sub-pixel type to be rendered with appropriate weighting factors, preventing color bleeding while maintaining brightness improvement from the W sub-pixel.
Solution Approach 2:
The invention applies local quality by using different rendering strategies for different sub-pixel types based on their specific characteristics. The first type sub-pixels (R and B) use one rendering approach, the second type (G) uses another, and the third type (W) uses a third approach, optimizing each locally to avoid the color bleeding issue that occurs when uniform weighting is applied to all sub-pixels.
2Productivity
If conventional sub-pixel rendering algorithm is used, then 16 channels data is transformed to 12 channels panel data, but shift flickers occur due to color bleeding issue
Solution Approach 1:
The invention segments the data transformation process by classifying sub-pixels into three types and applying specific rendering algorithms to each type. This segmentation prevents color bleeding during the 16-to-12 channel data transformation, thereby eliminating shift flickers and improving display stability while maintaining transformation efficiency.
3Ease of operation
If conventional sub-pixel rendering algorithm is used, then sub-pixel rendering is performed, but one pixel width slash line is disconnected when only one pixel outputs for one pixel inputs
Solution Approach 1:
The invention segments the rendering operation by classifying sub-pixels into three types and applying different rendering algorithms to each type. This segmentation ensures that slash lines maintain continuity across pixel boundaries by properly accounting for the contribution of each sub-pixel type, preventing disconnection issues while keeping the rendering process manageable.
