Display Panel Region Driving to Reduce RGB Flicker Dizziness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The rapid flickering of brightness and color on display panels can cause user dizziness due to the sequential display of full red, green, and blue screens.
Innovation Solution
A display driving device that interleaves the display of images across multiple regions or main pixels by outputting different color signals to specific regions during distinct periods, such as red to one set of regions, green to another, and blue to yet another, using a signal supplier and a panel with defined regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the panel sequentially displays full red, green, and blue screens to form a complete image, then the display can achieve complete color coverage and image formation, but the rapid flickering of brightness and color causes user dizziness
Solution Approach 1:
The display panel is divided into multiple regions (first region through ninth region) that are spatially separated. Different color signals (red, green, blue) are assigned to different regions simultaneously, rather than sequentially displaying full color screens. This segmentation eliminates the rapid flickering that causes dizziness while maintaining complete color coverage through spatial distribution.
2Productivity
If the panel uses rapid switching of full color screens to form images, then the image formation speed is maintained, but the flickering causes discomfort to users
Solution Approach 1:
The patent transitions from temporal dimension (sequential time-based color switching) to spatial dimension (simultaneous spatial distribution of colors across different regions). By displaying red, green, and blue colors in different spatial regions at the same time rather than switching them sequentially, the system maintains image formation capability while eliminating flicker-induced discomfort.
Data Source
AI summary
A display driving device comprises a signal supplier and a panel. The signal supplier is configured to output a first data signal, a second data signal, and a third data signal. The panel is coupled to the signal supplier. The panel includes a first region to a ninth region. During a first period, the first region, the second region, and the third region output a red signal based on the first data signal, the fourth region, the fifth region, and the sixth region output a green signal based on the second data signal, and the seventh region, the eighth region and the ninth region output a blue signal based on the third data signal. The red signal, the green signal, and the blue signal are different from each other.
