Transparent Display Defect Removal via Sensor-Adaptive Background
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses struggle to maintain a consistent visual effect of transparency due to changes in illumination and exposure of defects like scratches or stains on the background, which disrupts the desired view.
Innovation Solution
A display apparatus equipped with sensors to detect external light and a processor that generates and adjusts a content screen with a background image, including graphic objects and shadows, to adapt to environmental changes and remove defects by replacing them with matching areas from the background image, ensuring a seamless integration with the surrounding environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a background image is displayed to create a transparent window effect, then the visual effect is improved, but defects in the background area are exposed and spoil the view
Solution Approach 1:
The patent extracts and removes defect areas from the background image through image processing. The processor identifies defect regions and excludes them from the displayed background image, effectively taking out the harmful elements that spoil the transparent window effect while preserving the overall visual continuity.
Solution Approach 2:
The patent applies local quality adjustment by modifying only the defect areas of the background image while preserving the rest of the image. The processor selectively processes problematic regions with different characteristics (such as sockets, scratches, stains) to match surrounding areas, ensuring local corrections without affecting the global visual effect.
2Power
If color temperature is applied to the display apparatus, then the display function is enhanced, but the background image appears different from the actual background due to illumination changes
Solution Approach 1:
The patent applies parameter changes by adjusting the color temperature and brightness parameters of the displayed background image to match the actual surrounding environment. The processor dynamically modifies these parameters based on environmental conditions, ensuring that the displayed background remains consistent with the real-world background despite illumination changes.
Solution Approach 2:
The patent implements feedback by continuously monitoring the surrounding environment and adjusting the background image display accordingly. The system compares the displayed background with the actual environment and makes real-time corrections to maintain visual consistency, creating a closed-loop control system that adapts to changing lighting conditions.

AI summary
A display apparatus, including a display configured to display an image, at least one sensor configured to generate sensing data relating to at least one from among a direction and an intensity of external light projected onto the display from an external light source disposed around the display, a memory configured to store background image data relating to a background image of a background area behind the display, and a processor configured to generate a content screen based on the background image data and the sensing data and control the display to display the content screen, wherein the content screen may include at least one graphic object and a shadow corresponding to the at least one graphic object disposed on the background image, and at least one of a position and a shade of the shadow is changed in response to a change in the sensing data.
