Sub-pixel Rendering for Display Areas with Shared Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face challenges in maintaining image quality due to reduction in the number of sub-pixels, particularly when transitioning from traditional red, green, and blue sub-pixels to a configuration that includes white sub-pixels, which affects luminance and resolution.
Innovation Solution
A display device with a display panel divided into areas, utilizing a distribution unit to generate input image data, sub-pixel rendering units to process this data, and an extraction unit to output data to data lines, employing a re-sampling filter to generate red, green, blue, and white rendering data, and a blue shift algorithm to prevent image distortion at boundaries between areas.

1Illumination intensity
If the number of sub-pixels is reduced to include white sub-pixels, then luminance is improved, but resolution deteriorates
Solution Approach 1:
The display panel is divided into multiple areas, with each area containing red, green, blue, and white sub-pixels. This segmentation allows different regions to have different sub-pixel configurations, enabling the system to maintain resolution in critical areas while improving luminance in others through the inclusion of white sub-pixels.
Solution Approach 2:
The patent changes the sub-pixel configuration parameters by introducing white sub-pixels alongside traditional RGB sub-pixels. This parameter change enables the display to achieve higher luminance while maintaining resolution through compensatory rendering algorithms that process image data to account for the reduced number of color sub-pixels.
