Display Panel Compensation Wiring for Horizontal Crosstalk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In liquid crystal display panels, the parasitic capacitance between data lines and common electrodes causes voltage jumps, leading to horizontal crosstalk, which affects display quality and user experience, and existing inverse compensation methods require rewiring if they fail to achieve the desired effect, resulting in inefficient debugging and increased costs.
Innovation Solution
A display panel with configurable connecting wires for each common electrode, allowing flexible configuration of detection and feedback points to form an inverse compensation circuit without the need for rewiring, improving debugging efficiency and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If inverse compensation is set in the common electrode with fixed detection and feedback points, then the horizontal crosstalk is reduced, but the debugging efficiency is low and cost increases when rewiring is needed
Solution Approach 1:
The patent applies dynamics by making the connecting wires configurable rather than fixed. Each common electrode wire is provided with first and second connecting wires that can be selectively connected or disconnected based on debugging needs. This dynamic reconfigurability allows debugging personnel to adjust detection and feedback points without rewiring, thereby improving debugging efficiency while maintaining the compensation effect.
Solution Approach 2:
The patent implements parameter changes by allowing the configuration of connecting wires to be adjusted during debugging. The first and second connecting wires can be selectively connected to different detection and feedback points, changing the electrical connection parameters of the inverse compensation circuit. This enables optimization of the compensation effect without requiring physical rewiring, thus improving both debugging efficiency and maintaining reliability.
2Object-affected harmful factors
If inverse compensation is set in the common electrode, then the horizontal crosstalk is substantially reduced, but the cost increases due to rewiring requirements

This dynamic reconfigurability allows debugging personnel to adjust detection and feedback points without rewiring, thereby improving debugging efficiency while maintaining the compensation effect.

This enables optimization of the compensation effect without requiring physical rewiring, thus improving both debugging efficiency and maintaining reliability.
3Device complexity
If fixed connecting wires are used for common electrode, then the circuit structure is simple, but the adaptability is poor when compensation effect is insufficient
Solution Approach 1:
The patent applies dynamics by making the connecting wires configurable rather than fixed. Each common electrode wire is provided with first and second connecting wires that can be selectively connected or disconnected based on debugging needs. This dynamic reconfigurability allows debugging personnel to adjust detection and feedback points without rewiring, thereby improving debugging efficiency while maintaining the compensation effect.
Solution Approach 2:
The patent implements universality by designing the connecting wires to serve multiple functions. The first and second connecting wires can be configured for different purposes: one for detection and another for feedback, or both for detection, or both for feedback, depending on the specific compensation needs. This multi-functionality allows the same circuit structure to adapt to different compensation scenarios without requiring separate wiring configurations.
