Varying Illumination Control for Display Ambient Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing visual display systems lack functionality for providing immersive and comfortable ambient lighting in an inactive state, as they often suffer from uneven lighting due to light source degradation, which can result in visible color shifts and an unattractive room environment.
Innovation Solution
A visual display system with one or more illumination sources configured to provide varying peripheral illumination, controlled by a unit that synchronizes with a color scheme, allowing for passive backlighting that maintains even lighting and enhances room ambiance without the need for the display device to be active.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If static low-brightness lighting is provided in inactive state, then room lighting function is enabled, but uneven lighting and visible color shifts occur due to light source degradation
Solution Approach 1:
The patent applies dynamics by transitioning from static lighting to dynamic varying illumination. The control unit varies the illumination over time in the inactive state, which masks the appearance of degradation and maintains uniform lighting perception despite light source aging.
Solution Approach 2:
The patent changes the illumination parameter from constant to varying over time. By modulating the illumination intensity and/or color temperature dynamically, the system compensates for light source degradation effects and maintains consistent visual appearance.
2Ease of operation
If varying illumination is provided in inactive state, then lighting comfort and room ambiance are improved, but system complexity increases due to control requirements
Solution Approach 1:
The control unit is designed to perform multiple functions: it controls illumination during active state and varies illumination during inactive state. This multi-functionality reduces the need for separate control systems and minimizes overall device complexity.
Solution Approach 2:
The system uses its own existing control unit to manage both active and inactive state illumination, eliminating the need for external control devices and simplifying the overall system architecture.

AI summary
A visual display system for use in conjunction with a display device includes one or more illumination sources for illuminating a region surround the image display region; and a control unit configured to control the illumination sources to vary the illumination in an inactive state of the display device. The control unit is further configured to synchronize the varying illumination with a color scheme.
