Narrow Bezel Display Panel via Opposite Circuit Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display technologies face challenges in reducing the bezel width of display panels due to the difficulty in minimizing the amount of wiring required for integrating gate driving circuits, which limits the ability to achieve narrow or bezel-less displays.
Innovation Solution
The display panel design arranges the data driving integrated circuit and gate drive circuit on opposite sides, reducing the number of components needed in the remaining areas and narrowing the bezel width by optimizing the placement and routing of signal transmission lines and gate connecting lines, allowing for a more compact bezel design.

If gate drive circuit is integrated in the periphery region using GOA technology, then the bezel width is reduced, but the wiring complexity and difficulty of minimizing wiring in the periphery region increases
Solution Approach 1:
The invention divides the periphery region into four distinct areas (first, second, third, and fourth areas) with opposite sides containing different functional components. The data driving integrated circuit is placed in the first area, gate drive circuit in the third area, and signal transmission lines are strategically arranged in the second and fourth areas. This segmentation allows for optimized wiring paths that reduce overall wiring complexity while maintaining compact bezel dimensions.
Solution Approach 2:
The invention utilizes the two-dimensional layout of the periphery region by arranging components on opposite sides rather than concentrating them in one location. Signal transmission lines extend in a first direction across the display region, while gate connecting lines extend in a second direction (substantially perpendicular to the first direction), creating an orthogonal routing pattern that minimizes wiring interference and complexity within the constrained bezel space.
2Adaptability or versatility
If more wiring is added to integrate gate drive circuit in periphery region, then the gate drive functionality is achieved, but the bezel width increases
Solution Approach 1:
The invention merges the data driving integrated circuit and gate drive circuit into the periphery region, utilizing the available space on opposite sides of the display region. By combining these functional circuits with the display panel structure and strategically routing signal transmission lines through the second and fourth areas, the design achieves complete gate drive functionality without requiring additional external wiring that would increase bezel width.
Solution Approach 2:
The invention applies different wiring arrangements to different local areas of the periphery region. Signal transmission lines are specifically arranged in the second and fourth areas (opposite to each other), while gate connecting lines are arranged in the display region extending in a direction substantially perpendicular to the signal transmission lines. This localized optimization allows each area to serve its specific function with minimal wiring, achieving gate drive functionality while maintaining narrow bezel width.

AI summary
A display panel has a display area; and a peripheral area surrounding the display area, the peripheral area comprising a first area, a second area, a third area opposite to the first area, and a fourth area opposite to the second area. The display panel may further include a data driving integrated circuit provided in the first area; a gate drive circuit provided in the third area; and a plurality of signal transmission lines arranged in at least one of the second area and the fourth area. The configuration of the data driving integrated circuit and the gate drive circuit makes it possible to manufacture a display panel with a narrow bezel.
