Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional display technologies fail to effectively differentiate visual angle information across directions, leading to inefficient use of pixels and inability to meet diverse application requirements, as they maintain equal pixel ratios in all directions, which does not align with human sensitivity and display needs.
Innovation Solution
Inclining lenses relative to their initial optical axis to alter the pixel distribution ratio along orthogonal directions in each effective display region, allowing for differentiated display of visual angle information by changing the proportion of pixels in each direction, thereby enhancing angle resolution and resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional display technology maintains equal pixel ratios in all directions, then the display structure is simple and easy to manufacture, but the visual angle information cannot be differentiated across directions and pixel usage is inefficient
Solution Approach 1:
The patent applies asymmetry by inclining lenses at different angles relative to the display panel, creating asymmetric light transmission paths. This allows different directions to have different effective pixel ratios, enabling differentiated visual angle information display while using a standard rectangular display panel, thus achieving adaptability without requiring complex asymmetric panel designs
Solution Approach 2:
The patent changes the optical parameters of the display system by varying lens inclination angles. By adjusting these angles, the effective pixel ratio in different directions can be modified dynamically, allowing the same hardware structure to achieve different display effects for different visual angles, thereby improving adaptability without increasing structural complexity
2Measurement precision
If lenses are inclined to change pixel distribution ratios, then differentiated angle resolution is achieved, but the optical system becomes more complex
Solution Approach 1:
The patent applies local quality by assigning different lens inclination angles to different regions or directions of the display system. Each lens can be independently inclined to optimize the pixel distribution for its specific viewing direction, achieving high angle resolution locally without requiring the entire optical system to be complex
3Ease of manufacture
If equal pixel ratios are maintained in all directions, then manufacturing is simplified, but human sensitivity and display needs are not met
Solution Approach 1:
Instead of changing the physical arrangement of pixels in the display panel (which would be difficult to manufacture), the patent inverts the approach by using lens inclination to optically transform the effective pixel distribution. This maintains the simple rectangular panel structure for easy manufacturing while achieving the desired differentiated pixel ratios that align with human sensitivity through optical manipulation

AI summary
Various display control methods and apparatuses are provided. A method comprises inclining at least one lens relative to an initial optical axis thereof to change a ratio of pixels distributed along two directions in each effective display region of the at least one display unit corresponding to the at least one lens in a display system, wherein light emitted by each pixel in the effective display region of each display unit in the at least one display unit is transmitted to a visual angle range by a lens corresponding to the display unit in the display system, and the two directions comprise a first direction and a second direction parallel with the display unit and orthogonal with each other; and displaying a content to be displayed by the changed display system. Accordingly, differentiated display of visual angle information of two mutually orthogonal different directions can be realized.
