Time-Sharing Display Panel Sub-Pixel Sharing for High Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display panels face a bottleneck in improving resolution due to increased manufacturing demands, making it difficult to further enhance display quality without significant process complexity and cost.
Innovation Solution
The display panel employs a time-sharing mechanism among first, second, third, and fourth pixels formed by sharing sub-pixels within each pixel unit, allowing for high-resolution image display without increasing the number of pixel units, thereby reducing manufacturing costs and complexity.

Engineering Contradiction Analysis
1Manufacturing precision
If the resolution is improved by decreasing sub-pixel size and gap between sub-pixels, then the resolution increases, but the manufacturing process complexity and difficulty increase significantly
Solution Approach 1:
The patent applies time-division multiplexing to sequentially activate different pixel groups (first, second, third, and fourth pixels) within a single frame period. By dividing the display frame into multiple time slots and activating different pixel combinations in each slot, the system achieves higher effective resolution without requiring smaller physical sub-pixels or tighter manufacturing tolerances
Solution Approach 2:
The display panel divides pixels into multiple groups (first pixels, second pixels, third pixels, fourth pixels) based on different sub-pixel combinations. Each group is activated at different time intervals within a frame period. This segmentation allows the same physical sub-pixels to serve multiple logical pixel functions, achieving higher resolution without increasing manufacturing complexity
2Manufacturing precision
If more pixel units are added to improve resolution, then the resolution increases, but the manufacturing cost increases
Solution Approach 1:
Each physical sub-pixel is designed to serve multiple functions by being shared across different pixel groups. The same red, green, and blue sub-pixels are used to form first pixels, second pixels, third pixels, and fourth pixels at different time intervals. This multi-functionality eliminates the need for additional pixel units, maintaining manufacturing cost while achieving higher effective resolution
