Display Panel Connecting Lines for Corner Signal Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The non-display area in display apparatuses is increased, and the display area is reduced due to the arrangement of signal wires for transmitting image signals to corners and side surfaces, leading to reduced display quality and unevenness in pixel wiring configurations.
Innovation Solution
The display apparatus includes connecting lines disposed in the display area, minimizing the non-display area and reducing unevenness by optimizing the wiring configuration, particularly in the corner and side surfaces, using a matrix lattice of dummy and connecting lines with disconnection portions to enhance display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If signal wires are arranged to transmit image signals to corners and side surfaces, then image signal transmission is enabled, but the non-display area is increased and the display area is reduced
Solution Approach 1:
The patent transitions signal wire routing from the peripheral non-display area to the internal display area by introducing connecting lines that traverse through pixel areas. This dimensional repositioning allows signal transmission while minimizing the non-display area, as the connecting lines are integrated within the display region rather than occupying peripheral space.
Solution Approach 2:
The patent applies different wiring configurations to different regions: signal wires are routed through specific pixel areas (first, second, third, and fourth pixel areas) with varying connecting line arrangements. This localized optimization allows adaptive signal transmission while maintaining display area integrity in different zones of the display panel.
2Adaptability or versatility
If signal wires are arranged for corners and side surfaces, then signal transmission to edge regions is achieved, but wiring configuration unevenness increases
Solution Approach 1:
The patent implements region-specific connecting line configurations tailored to different pixel areas. The first connecting line structure differs from the second, third, and fourth connecting line structures, with each optimized for its specific location and function. This localized approach maintains wiring uniformity within each region while achieving comprehensive signal coverage across the display.
Solution Approach 2:
The patent divides the display area into multiple pixel areas (first, second, third, fourth pixel areas) with distinct connecting line arrangements. This segmentation allows each region to have optimized wiring configurations that maintain local uniformity while collectively achieving comprehensive signal transmission coverage.

AI summary
A display apparatus includes: a substrate including a display area in which a plurality of pixel areas is arranged, and a peripheral area adjacent to the display area and in which a pad portion including a plurality of pad electrodes is arranged; a first signal line and a second signal line in the display area on the substrate; a first connecting line electrically connected to the first signal line and connected to the pad portion, at least a portion of the first connecting line being in the display area; and a dummy line on a same layer as the first connecting line.
