Gate Transmission Line Segmentation for Display Panel Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The reduction of the frame in display devices to enhance appearance negatively impacts display quality due to increased wire density, particularly from gate transmission lines interfering with sub-pixels.
Innovation Solution
The display device design includes gate transmission lines with specific wire configurations, such as first, second, and third wires electrically connected in sequence, and optionally shielding electrodes, to minimize the negative influence on display quality by optimizing wire placement and overlap within the display area.

Engineering Contradiction Analysis
1Shape
If the frame of the display device is reduced to enhance appearance, then the appearance quality is improved, but the wire density increases and display quality deteriorates
Solution Approach 1:
The gate transmission line is divided into multiple segments (first gate transmission line, second gate transmission line, third gate transmission line) that are arranged in different layers and positions. This segmentation allows the wires to be distributed more efficiently, reducing their overall interference with sub-pixels while maintaining electrical connectivity across the display panel.
Solution Approach 2:
The patent utilizes multiple layers (first layer, second layer, third layer) to arrange gate transmission lines in three-dimensional space rather than confining them to a single plane. By stacking transmission lines across different layers, the design reduces wire overlap and interference with sub-pixels in the two-dimensional display plane, thereby improving display quality while maintaining a reduced frame structure.
2Object-affected harmful factors
If gate transmission lines are arranged to reduce interference with sub-pixels, then display quality is improved, but wire routing complexity increases
Solution Approach 1:
The multi-layer gate transmission line structure serves multiple functions simultaneously: it provides electrical connectivity across the display panel, reduces interference with sub-pixels through vertical layering, and enables flexible routing patterns. The same layered architecture that reduces interference also simplifies the routing strategy by providing dedicated pathways in different layers, thereby achieving interference reduction without proportionally increasing overall system complexity.

AI summary
A display device has a display area and a peripheral area and includes data lines, scan lines, gate transmission lines, and sub-pixels. The data lines and the gate transmission lines extend from the peripheral area into the display area. The data lines located in the display area extend along a first direction. The scan lines are located in the display area and extend along a second direction intersecting the first direction. The gate transmission lines are electrically connected to the scan lines. One of the gate transmission lines includes first, second, and third wires located in the display area. The first and third wires extend along the first direction. The second wire extends along the second direction. The first, second and third wires are electrically connected in sequence. The third wire is electrically connected to one of the scan lines.
