Asymmetric Display Panel Gate Line Segmentation for Signal Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Asymmetric hollow-out special-shaped display panels face image dislocation due to differential signal reception on their asymmetric sides, as conventional designs struggle to provide synchronous driving signals across cut-off and non-cut-off areas.
Innovation Solution
A special-shaped display panel with asymmetric display sub-areas is designed, featuring separate gate drive circuits on each side to ensure synchronous signal delivery, using double-side driving for continuous areas and single-side driving for cut-off areas, eliminating the need for gate lines to bypass non-display sub-areas and preventing signal dislocation.

1Area of stationary object
If gate lines extend continuously through the non-display sub-area in asymmetric hollow-out special-shaped display panels, then the display area can be maintained, but image dislocation occurs due to differential signal reception on asymmetric sides
Solution Approach 1:
The gate drive circuit is divided into two separate sets: a first gate drive circuit set for driving gate lines on one side of the non-display sub-area, and a second gate drive circuit set for driving gate lines on the other side. This segmentation allows independent signal generation for each asymmetric side, eliminating image dislocation while maintaining the hollow-out display area.
Solution Approach 2:
The patent applies asymmetric design by placing gate drive circuits on both sides of the display panel according to the asymmetric hollow-out shape requirements. The first and second gate drive circuit sets are positioned at different locations and configured differently to match the asymmetric display area, enabling precise control of gate lines on each side without causing image dislocation.
2Manufacturing precision
If gate lines are cut off in the non-display sub-area to prevent signal interference, then image dislocation is prevented, but the gate drive circuit complexity increases
Solution Approach 1:
The gate drive circuit is segmented into two independent sets positioned on opposite sides of the display panel. Each set drives the gate lines for its respective side, eliminating the need for complex routing through the non-display sub-area while maintaining precise image alignment.
3Reliability
If separate gate drive circuits are used for each side of the asymmetric display, then signal synchronization is achieved, but the device complexity increases
Solution Approach 1:
The gate drive function is segmented into two separate circuit sets, each responsible for one side of the asymmetric display. This segmentation achieves signal synchronization for each side independently while the overall system complexity remains manageable due to the modular architecture.
Solution Approach 2:
Each gate drive circuit set is locally optimized for its specific side of the display, with positioning and configuration tailored to the asymmetric hollow-out shape requirements. This local quality approach ensures signal synchronization while avoiding the need for a single complex centralized drive circuit.
