Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If glasses-free stereoscopic display technology is used, then viewing convenience is improved, but image separation quality deteriorates causing crosstalk
Solution Approach 1:
The patent applies parameter changes by adjusting the optical characteristics of the optical member, specifically the curvature radius and pitch of the stereoscopic lenses. By optimizing these parameters, the system achieves better image separation and reduces crosstalk while maintaining the glasses-free viewing convenience.
Solution Approach 2:
The patent implements a measurement and correction system that detects optical properties at multiple view points and uses this feedback to calculate correction coefficients. These coefficients are applied to adjust image data, thereby improving image separation quality and reducing crosstalk in the glasses-free display system.
2Manufacturing precision
If correction coefficients are calculated and applied for each view point, then image separation quality is improved, but measurement and processing complexity increases
Solution Approach 1:
The patent segments the display into multiple view points, with each view point having its own correction coefficient calculated and applied independently. This segmentation allows for precise control of image separation at each viewing angle while managing complexity through systematic processing.
Solution Approach 2:
The patent performs preliminary measurement of optical properties at multiple view points and pre-calculates correction coefficients before actual display operation. This preliminary action stores the correction data for efficient real-time application, reducing processing complexity during normal operation while maintaining high image separation quality.

AI summary
A display device comprises a display panel comprising a plurality of sub-pixels. An optical member is attached to the display panel. The optical member includes stereoscopic lenses. A display driver receives a correction coefficient for each view point of the display panel from a test apparatus for the display panel. The display driver corrects image data for each view point using the correction coefficient for each view point and drives the display panel so that an image associated with the corrected image data is displayed in a display area.
