Pixel Data Conversion for Delta Panel Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pixel data conversion methods for delta panels result in zigzag edges, line deformation, and color fringing due to the lack of consideration for the pixel size relationship between delta and strip panels, leading to reduced image resolution and quality.
Innovation Solution
A pixel data conversion method and apparatus that converts input video signals from RGB to YCrCb and scales them to match the horizontal resolution of the delta panel, using a low pass filtering mapper to adjust pixel positions and subpixel arrangements, effectively addressing the pixel size disparity and dislocation issues.

Engineering Contradiction Analysis
1Device complexity
If conventional pixel data conversion methods are used for delta panels, then the conversion process is simple, but zigzag edges, line deformation, and color fringing occur due to ignored pixel size relationships
Solution Approach 1:
The patent changes the conversion parameters by introducing a scaling factor that accounts for the pixel size relationship between strip and delta panels. The horizontal resolution is adjusted according to the formula: scaled horizontal resolution = original horizontal resolution × pixel size ratio, where the pixel size ratio is determined by the physical dimensions of the panels. This parameter adjustment eliminates zigzag edges and line deformation while maintaining simple conversion architecture.
2Productivity
If pixel data is directly converted without considering panel type, then processing is fast, but image resolution and quality are reduced
Solution Approach 1:
The patent performs preliminary action by pre-determining the pixel size ratio between strip and delta panels before the actual data conversion. This pre-calculated ratio is then applied during conversion to adjust the horizontal resolution appropriately. The preliminary preparation of the scaling factor allows fast processing while maintaining high image quality, as the conversion only requires multiplying by the pre-determined ratio rather than complex real-time calculations.
3Adaptability or versatility
If strip panel conversion methods are applied to delta panels, then compatibility is maintained, but half-pixel dislocation and line deformation occur
Solution Approach 1:
The patent applies local quality by treating odd-numbered and even-numbered horizontal lines differently in the conversion process. Odd lines use one mapping relationship while even lines use another, accounting for the half-pixel dislocation specific to delta panel architecture. This localized differentiation maintains compatibility with existing strip panel processing while correcting the positioning errors that cause line deformation and color fringing.

AI summary
A pixel data conversion method for display with delta panel arrangement converts an input video signal into a temporary video signal which is a first RGB signal with 640 horizontal resolution in a strip panel arrangement and converts the temporary video signal into an output video signal which is a RGB signal with 320 horizontal resolution in the delta panel arrangement. Each line of the output video signal has 960 pixels. A pixel size ratio is defined as a ratio of a pixel size of the delta panel to a pixel size of the strip panel. The 320 horizontal resolution is obtained by dividing the 640 horizontal resolution by the pixel size ratio and then by three.
