Display Data Spider Line Layout for Narrow Bezel Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses have a significant non-display area or bezel width that hinders the miniaturization and aesthetic appeal of display devices.
Innovation Solution
The display apparatus incorporates a base substrate with first data lines and connecting lines disposed in the display area, data pads in the peripheral area, and data spider lines extending between the display and peripheral areas, reducing the width of the non-display area by optimizing the layout of these components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the peripheral area width is reduced, then the display area ratio is improved, but the routing space for data lines and connecting lines is insufficient
Solution Approach 1:
The patent applies dimensionality change by routing data lines through the display area (utilizing the fourth dimension spatially) rather than only through the peripheral area. Specifically, data lines extend from the peripheral area through the display area to reach the data pads, effectively using the display area's routing capacity to reduce peripheral area requirements. This multi-dimensional routing approach resolves the contradiction by improving display area ratio while managing routing complexity through strategic path selection.
2Length of stationary object
If the peripheral area width is reduced, then the bezel width is minimized, but the connection between data lines and data pads becomes more difficult
Solution Approach 1:
The patent applies segmentation by dividing the data transmission path into multiple segments: data lines in the peripheral area, data lines extending through the display area, and data pads in the peripheral area. This segmentation allows each component to be optimized independently and simplifies the overall connection architecture. The connection contact holes are strategically positioned to bridge these segments, making the manufacturing process more manageable despite the reduced bezel width.
Solution Approach 2:
The patent uses connection contact holes as intermediary elements that facilitate the connection between data lines and data pads. These contact holes act as mediators that bridge the gap between the data lines extending through the display area and the data pads in the peripheral area, enabling reliable electrical connections even with minimized bezel width. The intermediary contact holes simplify the connection process by providing defined connection points.
3Area of stationary object
If data lines are routed through the display area, then the peripheral area width is reduced, but the display area routing capacity is consumed
Solution Approach 1:
The patent applies multi-functionality by utilizing the display area's routing capacity for dual purposes: both for displaying images and for routing data lines to data pads. The display area serves not only its primary function but also acts as a conduit for data line routing. This universal use of the display area for both display and routing functions enables peripheral area width reduction while managing the increased routing complexity through efficient space utilization.

AI summary
A display apparatus including a display area for displaying an image and a peripheral area that is a non-display area includes a base substrate, a first data line disposed in the display area on the base substrate, a first connecting line at least partially disposed in the display area on the base substrate and electrically connected to the first data line through a connection contact hole, a data pad disposed in the peripheral area, and a first data spider line disposed in the peripheral area between the data pad and the display area and electrically connected to the first connecting line and the data pad.
