Innovation Solution
An image simulation method and device that converts a curved image into a plane simulation image using the arc length and radius of curvature, projecting each arc segment onto a visual plane according to the formula AiAi+1=2Rcos(θ2-2i+12nθ)sinθ2n, allowing for display on a flat panel, which can be tangent or parallel to the curved display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If curved display is used to provide realistic perception and immersion, then visual experience is improved, but difficulty in evaluating and distinguishing performance is worsened
Solution Approach 1:
The patent creates a plane simulation image that copies and represents the curved display image on a flat plane. This allows evaluation of curved display performance using standard flat panel evaluation methods while maintaining the visual characteristics of the curved display through mathematical projection transformations.
2Adaptability or versatility
If curved image is displayed directly on curved display, then immersion is improved, but ability to display on flat panel for evaluation is worsened
Solution Approach 1:
The patent transforms the curved image parameters (arc length, radius of curvature) into plane image parameters through mathematical projection. This allows the same image content to be displayed on both curved displays for immersion and flat panels for evaluation, with the plane image being derived by changing the geometric parameters of the original curved image.
3Manufacturing precision
If arc length is divided into multiple arc segments for projection, then projection precision is improved, but calculation complexity is worsened
Solution Approach 1:
The patent divides the arc length into multiple arc segments to improve projection precision. Each arc segment is projected separately onto the visual plane, allowing for more accurate representation of the curved image. The segmentation enables precise control over the projection of each portion of the curved display.
Solution Approach 2:
The patent uses a sufficient number of arc segments (n>2) to achieve accurate projection without requiring an excessively large number that would make calculations impractical. This balanced approach provides adequate precision for evaluation purposes while maintaining reasonable computational complexity.
