Micropore Cover Display Correction for Pattern Overlap Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display systems where the front surface of a display part is covered with a patterned covering surface having a large number of micropores, the displayed image often overlaps with the pattern, making the image difficult to see.
Innovation Solution
A display system that includes a correction data storage part and an image processing part. The correction data is generated by gradation inversion of luminance distribution data appearing on the covering surface when a single color is uniformly displayed on the entire display part. This correction data is used to correct image data displayed on the display part, effectively canceling the pattern of the covering surface.

Engineering Contradiction Analysis
1Ease of manufacture
If the front surface of the display part is covered with a patterned covering surface having micropores, then the display can provide an appearance that conceals the display during nonuse, but the displayed image overlaps with the pattern making it difficult to see
Solution Approach 1:
The system performs preliminary measurement of the luminance distribution pattern through the covering surface, stores this pattern data, and then uses it to generate correction data in advance. This correction data is applied to pre-process the display image data before output, ensuring the pattern compensation is already built into the displayed image, thereby resolving the visibility issue while maintaining the concealing appearance function.
2Stability of the object's composition
If a patterned covering surface with micropores is used, then the display can be unified with the interior portion pattern, but the image quality deteriorates due to pattern overlap
Solution Approach 1:
The system changes the luminance parameters of the display image by applying correction data that compensates for the pattern effect. The correction data adjusts the brightness and contrast values pixel-by-pixel based on the measured luminance distribution, effectively canceling out the pattern overlay and restoring image quality while preserving the patterned covering surface for aesthetic unification.

AI summary
A display system, wherein a front surface of a display part is covered with a covering surface which is patterned, and has a number of micropores, includes a correction data storage part configured to store correction data generated by gradation inversion of luminance distribution data appearing on the covering surface when a single color is uniformly displayed on a whole of the display part, and an image processing part configured to correct image data to be displayed on the display part by the correction data read from the correction data storage part.
