Display Edge Light Integration for Low-Light Camera Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Low-light environments cause poor image quality in computer camera image data, and external lights are cumbersome and not easily portable, leading to degraded illumination during travel.
Innovation Solution
A display-based illumination system that repurposes a portion of the display screen as an edge light source to illuminate the user, providing constant light for improved image quality, with adjustable settings and automatic mode switching based on light conditions or user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If external lights are used to illuminate the user's face, then image quality is improved, but device portability and ease of operation deteriorate
Solution Approach 1:
The patent merges the illumination function with the display device by integrating edge lights into the display bezel. This combination eliminates the need for separate external lighting devices, maintaining portability while providing consistent illumination for camera capture during video calls and conferences.
Solution Approach 2:
The display device is designed to serve multiple functions: displaying visual content and providing illumination for camera capture. The edge lights are integrated into the display bezel, allowing the same device to both show information and illuminate the user's face, reducing the need for additional separate devices.
2Illumination intensity
If external lights are used to illuminate the user's face, then image quality is improved, but device complexity and cost increase
Solution Approach 1:
The illumination system is merged with the display device structure. The edge lights are integrated into the display bezel, sharing the same housing and power source, which reduces overall system complexity compared to using separate external lighting devices.
Solution Approach 2:
The display device performs dual functions as both a display and an illumination source. This multi-functionality reduces the total number of components needed in the system, simplifying the overall device architecture and reducing cost.
3Loss of information
If the display screen displays content on the entire area, then information display capability is maximized, but illumination capability is reduced
Solution Approach 1:
The display device is segmented into two functional zones: the display screen area for showing content and the edge light area in the bezel for illumination. This segmentation allows each zone to optimize its specific function without interfering with the other, maintaining full display area while providing dedicated illumination capability.
Solution Approach 2:
Different parts of the device have different functions: the central display area is optimized for information display, while the peripheral bezel area is optimized for illumination. This local differentiation of quality and function allows both display and illumination capabilities to coexist effectively.

Function Achieved in This Case
Enhances image quality by evenly illuminating the user's face, reducing shadows, and improving facial detail visibility in low-light conditions without the need for external lights.
Implementation Method 1
control the display device to provide an edge light along a different, second area of the display screen by emitting a constant light from the second area for an extended period of time to illuminate the user
Data Source
AI summary
A display-based user illumination system includes a memory that is configured to store program instructions and one or more processors operably connected to the memory. The program instructions are executable by the one or more processors to control a display device to display content to a user of the display device on a first area of a display screen of the display device. The program instructions are executable by the one or more processors to control the display device to provide an edge light along a different, second area of the display screen by emitting a constant light from the second area for an extended period of time to illuminate the user of the display device.
