Transparent Display Background Image Color Temperature Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display apparatuses fail to maximize the transparent effect by not considering color temperature in addition to brightness when processing background images, leading to a mismatch between the displayed background and the actual wall behind the display, affecting the aesthetic and visual experience.
Innovation Solution
A display apparatus with a memory, sensor, and processor that stores and processes background image data, generates sensing data related to external light, and performs image-processing based on both brightness and color temperature to ensure the background image appears consistent with the wall, thereby enhancing the transparent effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If image-processing is performed based on brightness only, then processing complexity is reduced, but the transparent effect is insufficient due to color temperature mismatch
Solution Approach 1:
The patent applies parameter changes by extending the image-processing from considering only brightness to considering both brightness and color temperature. The processor adjusts the background image's color temperature parameter to match the sensed ambient light, thereby improving the transparent effect quality without significantly increasing processing complexity.
Solution Approach 2:
The patent implements feedback by using a sensor to continuously detect ambient light conditions (brightness and color temperature) and using this information to dynamically adjust the background image processing. This closed-loop approach ensures the background image consistently matches the actual wall appearance under varying lighting conditions.
2Manufacturing precision
If image-processing is performed for both background image and content, then visual consistency is improved, but processing time increases
Solution Approach 1:
The patent applies local quality by selectively performing image-processing only on the background image while displaying content without processing. This approach maintains visual consistency for the background (which needs to match the wall) while avoiding unnecessary processing of content, thereby reducing overall processing time.
Solution Approach 2:
The patent implements partial action by performing image-processing only where necessary (on the background image) rather than processing all displayed elements. This selective approach achieves the required visual consistency for the transparent effect while minimizing processing time.
3Manufacturing precision
If background image is adjusted to match ambient light, then transparent effect is maximized, but energy consumption increases
Solution Approach 1:
The patent applies periodic action by adjusting the background image's brightness and color temperature periodically based on changes in ambient light conditions rather than continuously. The sensor detects light changes and triggers processing only when necessary, reducing energy consumption while maintaining the transparent effect.

AI summary
A display apparatus and a control method thereof are provided. The display apparatus may include a memory configured to store data related to a background image of an area behind the display apparatus, a display configured to display content by overlaying the content onto the background image, a sensor configured to generate sensing data related to external light that is ambient to the display apparatus, and a processor configured to perform image-processing of at least one of the background image and the content, based on a type of the content and the sensing data.
