Irregular Display Panel Edge Processing for Zigzag Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display panels with special-shaped edges suffer from zigzag edges, which existing methods attempt to mitigate by reducing pixel brightness, leading to increased power consumption and design costs, while still not fully eliminating the zigzag effect due to fixed edge positions.
Innovation Solution
An edge processing method that divides edge pixels into sets, dynamically adjusting their display in different frames to blur the edge position, thereby eliminating the zigzag effect without requiring changes to the panel design or significant resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If pixel brightness is reduced to weaken zigzag edge effects, then the zigzag edge effect is improved, but power consumption increases
Solution Approach 1:
The patent applies dynamics by making the edge pixel display state change over time. Edge pixels are divided into multiple sets that are sequentially activated and deactivated across different display frames. This dynamic switching creates a blurred visual effect that reduces the zigzag edge appearance while avoiding continuous brightness reduction, thereby lowering power consumption compared to constantly dimming edge pixels.
Solution Approach 2:
The patent implements periodic action by cycling through multiple sets of edge pixels in a repeating sequence. Each set of edge pixels is activated for a certain number of frames and then deactivated, with other sets taking over. This periodic activation and deactivation pattern creates the desired visual blur effect while distributing the display workload, reducing overall power consumption compared to continuously reducing brightness of all edge pixels.
2Shape
If pixel brightness is reduced to weaken zigzag edge effects, then the zigzag edge effect is improved, but design complexity increases
Solution Approach 1:
The patent applies segmentation by dividing edge pixels into multiple distinct sets (first set, second set, third set, etc.). Each set is independently controlled and activated in different display frames. This segmentation allows the system to manage edge pixel display complexity through software control rather than requiring complex hardware modifications to the panel design, thereby reducing design complexity while effectively reducing zigzag edge effects.
3Shape
If pixel brightness is reduced to weaken zigzag edge effects, then the zigzag edge effect is improved, but the improvement effect is limited
Solution Approach 1:
The patent enhances improvement effectiveness by dynamically switching between multiple sets of edge pixels rather than statically reducing brightness. This dynamic approach creates a more pronounced visual blur effect that better masks the zigzag edge appearance. The sequential activation and deactivation of different pixel sets produces a stronger perceptual effect compared to simple brightness reduction, thereby improving the reliability of the zigzag edge mitigation.

AI summary
The present disclosure provides an edge processing method for a display panel and a display panel having a device for processing an edge. The method includes: determining an irregular edge of the display panel and determining all edge pixels the irregular edge passes through; dividing all the edge pixels into n sets of edge pixels, where n≥2; and inputting frame image information to the display panel, wherein at least one set of the n sets of edge pixels is configured to display a frame image in at least one display frame, and is configured not to display the frame image in at least another display frame.
