Array Substrate Same Polarity Overlapped Leading Wires

Solution Overview

Problem

The existing array substrate designs with overlapped leading wires for data lines suffer from high capacitance due to opposite polarities, leading to increased power consumption and compromised image quality when data signals are inverted.

Innovation Solution

The array substrate features a configuration where first and second leading wires, arranged in different layers with an insulation layer in between, are overlapped in a way that data signals of the same polarity are introduced through them, reducing capacitance by ensuring same polarity data lines are connected to up-and-down overlapped wires.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If leading wires in different layers are arranged to be overlapped to reduce wiring region area, then the area of the wiring region is reduced, but very large capacitance is generated between the overlapped leading wires when data signals are inverted, increasing power consumption and affecting image quality

Engineering Contradiction:

Improvewiring region areaVSAvoidpower consumption

Core Design Contradiction:

Area of stationary objectVSLoss of energy

Solution Approach 1:

The patent inverts the conventional approach by ensuring that overlapped leading wires carry data signals of the same polarity rather than opposite polarities. This is achieved by connecting both leading wires in the overlap region to data lines of the same polarity (both odd or both even), thereby eliminating the capacitance issue while maintaining the space-saving overlapping structure

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent changes the polarity parameter of the data signals carried by overlapped leading wires from opposite to same. By controlling the connection configuration so that both leading wires carry signals of the same polarity, the capacitance between them is significantly reduced, solving the power consumption problem while maintaining the compact wiring design
