Display Panel Fan-Out Area Overlap for Narrow Borders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display panels have a large non-display area due to circuit design, hindering the achievement of narrow borders and full-screen technology.
Innovation Solution
The display panel design includes a display area and a fan-out area that partially overlap, with the display area extending into the fan-out area, reducing the non-display area by placing parts of the fan-out area within the display area, and incorporating specific electrode and layer configurations to optimize space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the fan-out area is placed below the display area (traditional design), then the circuit functionality is maintained, but the non-display area becomes too large
Solution Approach 1:
The patent applies dimensionality change by moving the fan-out area from a traditional planar arrangement below the display area to a three-dimensional overlapping configuration where the fan-out area is positioned above and partially overlaps with the display area. This vertical repositioning allows the circuit components to occupy space in the Z-dimension rather than consuming additional lateral space, thereby reducing the non-display area while maintaining all necessary circuit functionalities.
Solution Approach 2:
The patent implements nesting by placing the fan-out area within the spatial boundaries of the display area, creating a nested configuration where circuit elements are embedded within the display structure. Specifically, the fan-out area is positioned such that it overlaps with the display area, allowing circuit components to be nested within the overall panel structure without expanding the lateral footprint, thus reducing the non-display area.
2Area of stationary object
If the display area is increased to achieve narrow borders, then the full-screen effect is improved, but the space for circuitry is reduced
Solution Approach 1:
The patent resolves this contradiction by utilizing the vertical dimension to accommodate circuitry. The fan-out area is positioned above the display area in the Z-dimension, allowing full utilization of the lateral display area for imaging purposes while providing dedicated vertical space for circuit components. This dimensional separation enables maximum display area with adequate circuit integration space.
Solution Approach 2:
The patent applies segmentation by dividing the panel into distinct functional zones: the display area for imaging and the fan-out area for circuitry. The fan-out area is segmented into multiple regions including first fan-out areas above different sides of the display area and second fan-out areas in corners, allowing independent optimization of each circuit region while maintaining overall compactness and ease of manufacture.

AI summary
A display panel and a display device are provided. The display panel has a display area and a fan-out area. The fan-out area and the display area at least partially overlap. By arranging at least one part of the fan-out area in the display area, the display area of the display panel expends to the fan-out area, and therefore the area of the display area of the display panel is increased to reduce the area of the non-display area occupied by the fan-out area. That is, the problem that the non-display area of the display panel is too large is alleviated and the narrow border and full screen technology are further implemented.
