Display Device Matching Wall Surface via Rear Camera
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices with large screens often appear out of harmony with their surroundings when turned off, creating an unsightly black surface that disrupts the aesthetic continuity of the environment.
Innovation Solution
A display device equipped with a front camera, rear camera, sensor unit, and processor that captures user and wall surface images, calculates user position and distance, and adjusts the displayed image to match the surrounding wall surface, compensating for distortions and adjusting brightness based on lighting conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a large size screen is used to provide high-resolution image quality and deep immersion, then image quality and viewing experience are improved, but the display device appears out of harmony with surroundings and creates an unsightly black surface when turned off
Solution Approach 1:
The display device captures an image of the wall surface behind it using a rear camera, then displays this captured image on the screen. This copying approach allows the display to show content that matches the surrounding environment, eliminating the harsh black surface effect when the device is not actively displaying media content.
Solution Approach 2:
The display device dynamically changes the color and content of the screen by displaying the captured wall surface image instead of a black screen. This color adaptation allows the display to blend with the surrounding environment and create visual harmony with the installation location.
2Loss of energy
If the display device shows a black screen when turned off, then power consumption is reduced, but the black screen gives a sense of incompatibility and disrupts the aesthetic continuity of the environment
Solution Approach 1:
The display device operates in periodic cycles, switching between displaying the captured wall image (aesthetic mode) and displaying actual media content (functional mode). During periods when no media is being played, the screen shows the wall surface image to maintain aesthetic continuity, while consuming minimal power compared to maintaining a traditional off state.
3Object-generated harmful factors
If the display device captures and processes wall surface images in real-time, then aesthetic harmony with surroundings is improved, but device complexity and processing requirements increase
Solution Approach 1:
The display device captures the wall surface image in advance and stores it for later display. This preliminary action eliminates the need for continuous real-time processing, as the captured image can be held in memory and displayed whenever the device is not actively showing media content, significantly reducing ongoing processing requirements.
Solution Approach 2:
The display device uses its own rear camera and processor to capture and display the wall surface image, making the system self-sufficient for achieving aesthetic harmony. This self-service approach eliminates the need for external control systems or additional hardware, keeping the added complexity minimal while achieving the desired aesthetic effect.
