Dynamic Sub-Pixel Sharing for Display Panel Edge Contrast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sub-pixel rendering technologies struggle to accurately display contrast in edge regions of images, leading to distortion due to fixed sub-pixel sharing, which limits the improvement of image resolution and clarity.
Innovation Solution
A method of driving a display panel that dynamically determines the luminous intensity of sub-pixels by comparing color component differences between adjacent logical pixel groups, allowing for flexible sub-pixel sharing based on calculated differences to enhance edge region contrast and reduce distortion.

Engineering Contradiction Analysis
1Measurement precision
If sub-pixel rendering technology shares fixed sub-pixels among adjacent pixel units, then the sensory resolution of the display panel is improved, but the contrast of edge regions deteriorates and distortion occurs when colors change rapidly
Solution Approach 1:
The patent applies dynamics by making the sub-pixel sharing configuration adaptive rather than fixed. The driving device dynamically adjusts which sub-pixels are shared among logical pixels based on the actual image content and color component differences. This allows the system to optimize for both resolution enhancement and edge contrast preservation depending on the local image characteristics, resolving the contradiction between improved sensory resolution and maintained edge region accuracy
Solution Approach 2:
The patent changes the parameter of sub-pixel sharing configuration from a static fixed assignment to a dynamic parameter that varies based on color component differences. By calculating differences in color components (R, G, B values) between adjacent pixel units and adjusting the sharing scheme accordingly, the system can maintain accurate edge contrast while still achieving resolution enhancement through sub-pixel rendering

AI summary
The present invention provides a method of driving a display panel and a driving device. The present invention determines sub-pixels shared by sub-pixel rendering technology through comparing differences of the color components, and the sub-pixels shared by the display image are not fixed. Since the sub-pixels with the smallest absolute value of the color component difference are selected for sharing, a contrast of an edge region of an image is improved, and distortion of an edge region of an image is reduced.
