Microporous Cover Display Luminance Correction for Image 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 many 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 to store data generated by inverting the luminance distribution of the covering surface when a single color is uniformly displayed, and an image processing part that corrects image data to be displayed on the display part using this correction data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
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 and allows display light to transmit when lit, but the displayed image overlaps with the pattern on the covering surface, making the image difficult to see
Solution Approach 1:
The invention performs preliminary correction by generating correction data that compensates for the pattern effect before the actual display operation. The correction data is stored in advance and applied to the image data prior to display, pre-canceling the pattern interference that would otherwise occur when the display is activated through the microporous covering surface.
Solution Approach 2:
The invention changes the luminance parameters of the displayed image by applying correction data that adjusts brightness values across different regions. This parameter transformation compensates for the non-uniform light transmission caused by the patterned covering surface, ensuring that the displayed image maintains proper contrast and visibility despite the underlying pattern.
2Stability of the object's composition
If a patterned covering surface is used to hide the display when not in use, then the instrument panel can be unified into a single pattern, but the pattern on the covering surface interferes with the displayed image quality
Solution Approach 1:
The correction data is generated and stored in advance, performing the compensation action before the display is actually used. This preliminary correction ensures that even though the physical covering surface remains patterned, the visual output will have uniform quality by pre-counteracting the pattern interference through luminance adjustment.
Solution Approach 2:
The invention introduces correction data as an intermediary element between the image source and the display output. This digital intermediary processes the image data to compensate for the physical pattern on the covering surface, acting as a mediator that reconciles the conflict between the aesthetic uniformity of the panel and the quality of the displayed image.

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 large 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.
