Display Data-Line Routing Through Display Area for Narrower Bezels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses face challenges in reducing the width of the peripheral non-display area, also known as the bezel, which affects the overall size and aesthetic appeal.
Innovation Solution
The display apparatus design incorporates connecting lines within the display area rather than the peripheral area, allowing for a reduction in the width of the non-display area by arranging data spider lines in a manner that minimizes wire resistance and enables the use of standard data driving chips without signal order changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If connecting lines are disposed in the peripheral area, then the data lines can be connected to the data pad, but the width of the peripheral area increases
Solution Approach 1:
The patent applies dimensionality change by routing the first connecting line through the display area (utilizing the vertical dimension) rather than confined to the peripheral area. The connecting line extends from the data pad in the peripheral area, passes through the display area, and connects to the data line, thereby utilizing the depth/vertical dimension to reduce the horizontal width of the peripheral area.
2Length of stationary object
If the peripheral area width is reduced, then the bezel portion is reduced, but the connection of data lines becomes more difficult
Solution Approach 1:
The patent segments the connecting line into multiple portions: a first portion extending from the data pad in the peripheral area, a second portion extending through the display area, and a third portion connecting to the data line. This segmentation allows each portion to be optimized for its specific location and function, making the overall connection feasible despite the reduced peripheral area width.
Solution Approach 2:
By routing the connecting line through the display area (utilizing the vertical dimension), the patent creates sufficient space for the connection path without increasing the horizontal width of the peripheral area. This dimensional transition enables the connection to be maintained while achieving a narrower bezel.
3Reliability
If connecting lines are arranged to minimize wire resistance, then signal transmission is improved, but the layout complexity increases
Solution Approach 1:
The patent applies local quality by optimizing the connecting line layout specifically in the display area where the first connecting line passes through. The second portion of the connecting line is arranged to minimize wire resistance in this critical region, with considerations for wire width, spacing from other lines, and path optimization. This localized optimization improves signal transmission without requiring complete redesign of the entire layout.

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.
