Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional curved-surface displays are limited by poor flexibility, resulting in suboptimal picture quality when viewed from off-center locations due to fixed curvature designs, which fail to accommodate multiple viewers and varying observation angles, leading to visual distortions and chromatic aberrations.
Innovation Solution
An adjustable curved-surface display system that uses an image sensor and processing unit to capture viewer location and angle information, calculating optimal curvature for each viewer to dynamically adjust the display surface, thereby improving picture quality across different viewing positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a fixed curvature design is used to improve picture quality at central viewing location, then visual effect is improved for single observer, but picture quality deteriorates for multiple viewers at different locations
Solution Approach 1:
The patent applies dynamics by making the curvature of the display surface adjustable rather than fixed. The curvature adjustment unit enables the display to dynamically change its curvature radius according to different viewing conditions, allowing optimal picture quality for multiple viewers at different locations while maintaining the visual advantages of curved surfaces.
2Illumination intensity
If a large screen size is used to achieve surround viewing experience, then visual advantages are improved, but the thickness and structural complexity increase
Solution Approach 1:
The patent uses dynamics by implementing an adjustable curvature mechanism that allows the display to optimize its visual performance without requiring a larger fixed size. The curvature adjustment unit enables the same physical screen to adapt its visual characteristics dynamically, achieving surround viewing experience benefits without increasing structural complexity.
3Shape
If a curved surface is created by physical bending of flat panel, then visual effect is improved, but the flexibility and ease of adjustment deteriorate
Solution Approach 1:
The patent directly applies dynamics by designing a display with adjustable curvature capability. The curvature adjustment unit enables the display to dynamically modify its shape from flat to various curved states, providing both the visual advantages of curved surfaces and the flexibility to adapt to different viewing scenarios without permanent physical bending.
Solution Approach 2:
The patent applies parameter changes by modifying the curvature radius parameter of the display surface. The curvature adjustment unit enables continuous or discrete changes in the curvature parameter, allowing the display to optimize its visual performance by adjusting this key geometric parameter according to different viewing conditions and requirements.
