Display Panel Narrow Bezel via Perpendicular Substrate Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies struggle to achieve a narrow bezel on hard screens due to the limitations of binding region bending technologies, which cannot be applied to rigid screens, resulting in a larger lower bezel width and reduced screen-to-body ratio.
Innovation Solution
A display panel design featuring a first substrate with a unique structure, including a first surface, a second surface perpendicular to the first surface, and at least one third surface connecting them, with the second surface having a thinner thickness than the first surface, and first connection portions disposed on the second surface to transmit display signals through first signal lines tracing through the third surface and first surface.

1Length of stationary object
If binding region bending technology is applied to reduce bezel width, then the lower bezel width is reduced, but this technology cannot be applied to hard screens
Solution Approach 1:
The substrate is divided into a display region and a non-display region, with the non-display region further segmented into a first non-display region and a second non-display region separated by a groove. This segmentation allows the binding region to be positioned in the second non-display region below the groove, enabling the display region to extend closer to the edge and reduce the lower bezel width while maintaining structural integrity for hard screens.
2Length of stationary object
If the non-display region width is reduced to achieve narrow bezel, then the screen-to-body ratio increases, but the signal line may be more prone to breaking
Solution Approach 1:
A groove is formed in the substrate extending from the groove opening to a predetermined depth, creating a protective structure before the signal lines are routed. The binding region is positioned below this groove in the second non-display region, allowing the groove to act as a cushioning structure that protects the signal lines from mechanical stress and potential breakage, while still enabling the non-display region width to be reduced for a narrow bezel design.

AI summary
A display panel and a manufacturing method thereof. The display panel has a display region and a non-display region located on at least one side of the display region and includes a first substrate. The first substrate has a first base located at a non-display region and a second base located at the display region, and the first base includes a first surface, a second surface perpendicular to the first surface, and at least one third surface connecting the first surface and the second surface. The second surface is inseparable from the first substrate. The display panel further includes multiple first connection portions disposed on the second surface and multiple first signal lines which trace through the first surface and the third surface. The multiple first connection portions are electrically connected to the multiple first signal lines correspondingly to transmit display signals.
