Ambience Lighting Color Compensation for Display Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ambience lighting systems for display devices, such as TVs, often fail to provide an optimal viewing experience when the wall color behind the device differs from white, as the reflected light colors do not match the screen colors, limiting the viewing experience for users with colored walls.
Innovation Solution
An ambience lighting system that includes light sources mounted at the periphery or rear of the display device, an input means for receiving wall color information, and a processor that adjusts the emitted light color to match the wall color, using pre-defined rules or a look-up table to ensure the reflected light from the wall matches the screen colors, allowing users to customize the lighting to their environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the ambience light is emitted to match screen colors, then the viewing experience is maximized for white walls, but the reflected colors mismatch the screen colors for colored walls
Solution Approach 1:
The system changes the color parameters of the ambience light based on the detected wall color. The processor adjusts the emitted light's color temperature and hue to compensate for the wall's color characteristics, ensuring that the reflected light always matches the screen colors regardless of wall color variations.
Solution Approach 2:
The system uses wall color detection to obtain feedback about the environment, then adjusts the ambience light color accordingly. The detected wall color information feeds back to the processor, which calculates the appropriate compensation and modifies the light emission in real-time to achieve accurate color matching.
2Adaptability or versatility
If the ambience light color is adjusted to match different wall colors, then compatibility with various wall colors is improved, but the system complexity increases
Solution Approach 1:
The system introduces an intermediary wall color detection mechanism that simplifies the overall control process. Instead of directly controlling complex color transformations, the system uses the detected wall color as an intermediary parameter to drive the adjustment of ambience light, making the system more manageable despite increased adaptability.
Solution Approach 2:
The system performs preliminary wall color detection and analysis before emitting the ambience light. By pre-determining the wall color characteristics and calculating the required compensation in advance, the system simplifies the real-time control complexity while maintaining high adaptability to different wall colors.

Function Achieved in This Case
This solution enables a more universal viewing experience by ensuring the reflected colors from the wall align with the screen colors, improving color matching for various wall colors and enhancing the overall viewing experience for a wider range of users without the need for constant adjustments.
Implementation Method 1
emit an ambience light onto a wall behind the display device such that the emitted light matches the video being shown... the light reflected from the wall towards a viewing area

AI summary
This invention relates to an ambience lighting system for a display device, where light sources are mounted at the periphery or at the rear side of the display device for emitting an ambience light onto a wall behind the display device. An input means receives color information indicating the color of the wall. A processor then adjusts the color of the emitted ambience light to the received color information of the wall such that the light reflected from the wall towards a viewing area of the display device matches the screen colors of the display device.
