Display Panel Dam Structure for Camera Cutout Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices with irregularly-shaped screens for full-screen designs often eliminate components like front flashlights and alert lights due to the camera cutout, resulting in a loss of lighting and special reminder functions.
Innovation Solution
A display panel with a dam structure between the display region and the camera cutout area, featuring a light-emitting function layer with separate components for the display region and the boundary area, including thin-film transistor devices and boundary driving circuits to enable lighting and reminder functions around the camera cutout.

Engineering Contradiction Analysis
1Length of stationary object
If a cutting hole is formed in the display region for a front camera, then the border width is reduced, but lighting components (front flashlight) and alert light components are eliminated
Solution Approach 1:
The display panel is divided into a display region and a boundary region, with the boundary region specifically allocated for lighting and alert light functions. This segmentation allows the display region to maintain full-screen display while the boundary region preserves essential lighting components that would otherwise be eliminated by the camera cutout.
Solution Approach 2:
The lighting components are relocated from the traditional border area to a newly defined boundary region that surrounds the display region. This spatial reorganization in a different dimensional arrangement allows lighting functions to coexist with the camera cutout without compromising display area.
2Length of stationary object
If a cutting hole is formed in the display region for a front camera, then the border width is reduced, but the special reminder function is eliminated
Solution Approach 1:
The display panel is divided into a display region and a boundary region, with the boundary region specifically allocated for lighting and alert light functions. This segmentation allows the display region to maintain full-screen display while the boundary region preserves essential lighting components that would otherwise be eliminated by the camera cutout.
Solution Approach 2:
The boundary region serves multiple functions: it provides structural support for the display panel, enables lighting functions through the front flashlight component, and implements special reminder functions through the alert light component. This multi-functionality allows the boundary region to compensate for the loss of traditional border functions.
3Adaptability or versatility
If a dam structure is added between the display region and boundary region, then the lighting and alert light functions are preserved, but the device complexity increases
Solution Approach 1:
The dam structure physically segments the display region from the boundary region, allowing independent optimization of each area. The display region focuses on display functionality while the boundary region handles lighting and alert light functions, with the dam structure serving as a functional boundary that simplifies the overall design by clearly defining regional responsibilities.
Solution Approach 2:
The dam structure acts as an intermediary element between the display region and boundary region, providing mechanical support and defining the spatial relationship between these two functional areas. This intermediary structure enables the coexistence of different functional regions without requiring complex integration schemes.
