Irregular Display Panel Transition Area Light-Shielding Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels with irregular boundaries, such as circular or curved screens, suffer from jagged visual effects due to the mismatch between pixel units and boundary lines, leading to an uneven display quality near the edges.
Innovation Solution
A display panel design with a transition area divided into multiple sub-areas, each with specific light-shielding block configurations to reduce brightness and smooth out grayscale transitions, mitigating the jaggedness issue by strategically placing light-shielding blocks within sub-pixels to reduce light transmittance and create a more uniform brightness gradient.

1Area of stationary object
If pixel units are arranged to follow the irregular boundary line, then the display area can be maximized, but the pixel units form a jagged shape that causes visual jaggedness
Solution Approach 1:
The transition display area is divided into multiple sub-areas (first transition sub-area, second transition sub-area, third transition sub-area) along the extension direction of the irregular boundary. Each sub-area contains pixel units with progressively adjusted light-shielding block configurations, segmenting the transition from full brightness to reduced brightness to eliminate visual jaggedness while maintaining display area coverage.
Solution Approach 2:
Different regions of the display panel are assigned different light-shielding characteristics. Pixel units in the transition display area have light-shielding blocks with specific areas and positions that differ from pixel units in the main display area. The light-shielding block area and position are locally adjusted in each sub-area to create a smooth brightness gradient that matches the irregular boundary shape.
2Stability of the object's composition
If light-shielding blocks are added to sub-pixels in the transition area, then brightness uniformity is improved, but the device structure becomes more complex
Solution Approach 1:
The light-shielding blocks are configured with specific parameter variations: in the first transition sub-area, light-shielding blocks have a first area and are positioned at a first position; in the second transition sub-area, they have a second area and second position; in the third transition sub-area, they have a third area and third position. By systematically varying these parameters across sub-areas, brightness uniformity is achieved while the complexity is managed through a structured, scalable configuration approach.
