Touch Wiring Layout for Narrow Frame Mobile Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing layout of touch wires in display panels results in a larger blind area and makes it difficult to design multiple touch binding terminals centrally, leading to a wider frame that is not conducive to a light and narrow design.
Innovation Solution
The display panel incorporates a touch layer with touch wires arranged in both the first and second directions, featuring protruding portions and connecting portions that allow for a concentrated layout from the display area to the non-display area, enabling centralized design of touch binding terminals and reducing the frame width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If touch wires all extend along the first direction from display area to non-display area, then the connection to touch binding terminal is simplified, but the blind area of non-display area becomes larger and frame width increases
Solution Approach 1:
The patent introduces touch wires extending along the second direction (perpendicular to the first direction) in addition to the existing first direction extension. This dimensional change allows touch wires to connect to touch binding terminals at multiple locations along the second direction, reducing the blind area while maintaining connection simplicity through the structured arrangement of touch electrode columns and rows.
2Reliability
If touch wires extend from near one end of touch electrode column to non-display area, then the electrical connection is established, but centralized design of multiple touch binding terminals becomes difficult
Solution Approach 1:
The patent segments the touch wire connections into multiple independent paths by introducing touch electrode columns and rows arranged in a grid pattern. Each column can connect to touch binding terminals independently, allowing centralized design of multiple terminals while maintaining reliable electrical connections through the segmented touch wire structure that extends along both first and second directions.
3Adaptability or versatility
If frame width in first and second directions is increased to accommodate touch binding terminals, then terminal design is enabled, but narrow frame design requirement is not met
Solution Approach 1:
The patent nests multiple touch binding terminals within the same non-display area by arranging touch electrode columns and rows in a compact grid pattern. The touch wires extend along both first and second directions to connect these nested terminals, allowing multiple terminals to be accommodated within a reduced frame width while maintaining design capability through the nested arrangement.

AI summary
A display panel and a display terminal are provided. Touch wires include a first touch wiring portion arranged along a first direction and a second touch wiring portion arranged along a second direction. Through an arrangement of the second touch wiring portion, the touch wires are concentrated and extended from a display area to a non-display area. Touch binding terminals can be designed in a centralized manner, and a width of a frame on which the touch binding terminals are arranged in the first direction and the second direction is reduced.
