Asymmetric Display Panel Edge Structure for Narrow Bezels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display panel technologies face challenges in minimizing frame size while maintaining high light transmittance, particularly in areas like under-screen cameras or fingerprint recognition, as bending the non-display area can block high light transmittance regions, reducing overall light transmittance.
Innovation Solution
A display panel design with a non-display area that includes first and second sub-edges, where the distance from the first sub-edge to the display area is smaller than from the second sub-edge, allowing for selective bending to avoid blocking high light transmittance areas, thereby maintaining light transmittance and enabling a narrow frame design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the non-display area is bent to the backlight side to reduce frame size, then the frame area is reduced, but the light transmittance of high light transmittance areas is blocked and reduced
Solution Approach 1:
The non-display area is divided into multiple sub-edges (first sub-edge, second sub-edge, third sub-edge, fourth sub-edge) with different distances to the display area. This segmentation allows selective bending of specific portions while preserving others, enabling the frame to be narrowed without blocking high light transmittance areas like the under-screen camera region.
Solution Approach 2:
Different sub-edges of the non-display area are assigned different functional characteristics based on their distance to the display area. The first sub-edge (closer to display area) is designed to be bent, while the second sub-edge (farther from display area) remains unbent to preserve light transmittance. This local differentiation resolves the contradiction between frame reduction and light transmission.
2Length of moving object
If the non-display area is bent closer to the display area, then the frame size is reduced, but the aesthetic appeal and light passage of high light transmittance areas are compromised
Solution Approach 1:
The non-display area is segmented into multiple sub-edges with progressively different distances to the display area. This allows the frame to be narrowed at specific locations (first sub-edge) while maintaining the original shape and aesthetic appeal at other locations (second sub-edge) that remain unbent.
Solution Approach 2:
The sub-edges are arranged asymmetrically with different distances to the display area, allowing selective bending operations. The first sub-edge is bent to reduce frame width, while the second sub-edge remains straight to preserve aesthetic appeal, creating an asymmetric but functional design.

AI summary
The present application discloses a display panel and a display device. The display panel includes a display area and a non-display area. The display area includes a first functional area and a second functional area surrounded by the first functional area. A light transmittance of the second functional area is higher than a light transmittance of the first functional area. The non-display area is located on one side of the first functional area away from the second functional area. The non-display area comprises a first sub-edge and a second sub-edge which form an edge of the display panel. A distance from the first sub-edge to the first functional area is smaller than a distance from the second sub-edge to the first functional area, and the first sub-edge is arranged closer to the second functional area than the second sub-edge.
