Solution Overview

Problem

The increasing density of wires in display panels leads to uneven signal transmission, causing instability and affecting the display effect due to different signal losses at various positions.

Innovation Solution

Adjusting the lengths of connection wires to ensure balance and similarity in total lengths and resistances, ensuring balanced signal transmission by intersecting sub-sections and sub-wires, and using virtual wires to compensate for length differences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If wires are densely disposed to increase resolution ratio and screen-to-body ratio, then the resolution and screen-to-body ratio are improved, but the signal transmission stability deteriorates due to uneven signal loss at different positions

Engineering Contradiction:
Improveresolution ratioVSAvoidsignal transmission stability
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent applies local quality by making different connection wires have different configurations (straight vs. bent shapes, different lengths) according to their specific positions in the display panel. This allows each wire to be optimized for its local signal transmission needs, compensating for position-dependent signal loss while maintaining high wire density for high resolution.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent changes physical parameters of connection wires (length, shape, routing path) to compensate for signal loss. By adjusting these parameters based on position, the patent maintains signal transmission stability even with densely packed wires required for high resolution displays.

Inventive Principle:
Principle #35Parameter changes
