Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Special-shaped display panels experience uneven brightness between active and special-shaped regions, leading to display uniformity issues.
Innovation Solution
A display panel design that includes a gate driving circuit, first and second pixel modules with different numbers of columns, and a load structure in a non-display region electrically connected to the gate wiring to enhance the loading of gate driving signals for the second pixel module, ensuring uniform brightness across regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a special-shaped display screen is used, then the display form is more versatile, but the brightness uniformity between active and special-shaped regions deteriorates
Solution Approach 1:
The patent applies local quality by configuring different numbers of pixel circuit columns in different display regions. Specifically, the first display region has a greater number of columns of pixel circuits than the maximum number of columns in the second display region, creating region-specific pixel densities that compensate for the special-shaped geometry and achieve uniform brightness across the display.
2Shape
If the number of pixel circuit columns is reduced in the second display region, then the display form can be special-shaped, but the brightness of the special-shaped region becomes different from the active display region
Solution Approach 1:
The patent implements local quality by making the first pixel module have a greater number of columns of pixel circuits than the second pixel module, matching the different geometric requirements of each region while maintaining brightness uniformity through differentiated pixel configurations.
Solution Approach 2:
The patent applies parameter changes by modifying the number of pixel circuit columns in different regions. The first display region uses a greater number of columns of pixel circuits compared to the second display region, changing the structural parameter to compensate for the special-shaped geometry and achieve uniform brightness.
3Shape
If the gate wiring length is increased to cover the second display region, then the special-shaped display can be formed, but the loading of the gate driving signal becomes insufficient
Solution Approach 1:
The patent applies local quality by having the gate driver circuit provide different numbers of gate driving signals to different regions. The gate driver circuit is configured to provide a greater number of gate driving signals to the first pixel module than to the second pixel module, optimizing the driving capability for each region's specific requirements.
