Curved Display Horopter Alignment Signal Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flat displays fail to provide a realistic viewing experience due to the mismatch between the flat display surface and the spherical human eye, leading to a gap between the display and the horopter surface, which reduces the perceived image quality and realism even when the screen is enlarged.
Innovation Solution
A curved display system that includes a display panel with a controller capable of determining whether the surface is flat or curved, generating a curved image signal corresponding to the viewer's horopter surface, and using an eye tracking sensor to adjust image distribution accordingly, ensuring the image is processed and displayed in a way that aligns with the viewer's eye movement and curvature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a flat display surface is used, then the display structure is simple and manufacturing is easier, but the image realism and attraction power are reduced due to the gap between the flat display and the spherical horopter surface
Solution Approach 1:
The patent applies curvature to the display surface to match the spherical shape of the human eye's horopter surface. The curved display surface eliminates the gap between the display and the horopter surface, thereby improving image realism and attraction power while maintaining manufacturing feasibility through flexible display technologies.
2Area of stationary object
If the screen size is enlarged to provide a better viewing experience, then the display area increases, but the gap between the display surface and the horopter surface increases, reducing perceived image quality
Solution Approach 1:
By curving the display surface to match the horopter surface geometry, the patent enables larger display areas while maintaining consistent image quality across the entire screen. The curved surface ensures that all pixels remain at appropriate distances from the viewer's eye, preventing the quality degradation that occurs with enlarged flat displays.
3Manufacturing precision
If a curved display panel is used, then the image alignment with the horopter surface is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent employs parameter changes in the display panel's physical configuration, transitioning from a flat to a curved state. This allows the display to adapt its shape parameter to match the horopter surface, improving image alignment while managing complexity through controlled geometric transformation rather than fundamentally changing the display technology.
4Device complexity
If conventional flat display processing is used, then the signal processing is straightforward, but the attraction power and viewer engagement are reduced
Solution Approach 1:
The patent applies preliminary action by pre-calculating and pre-processing the image signals to account for the curved display geometry and horopter surface characteristics. This allows the curved display to present optimally aligned images without requiring complex real-time processing during operation, thereby maintaining attraction power while managing processing complexity.

AI summary
A curved display and a method for processing an image thereof are discussed. The curved display according to an embodiment includes a display panel selectively including a flat surface and a curved surface, and a controller including a signal processor for receiving image signal information from an external system, converting the image signal information into an image signal appropriate for the display panel, and distributing the image signal to the display panel, and a curved image generator for receiving the image signal and generating a curved image signal varied to correspond to a viewer's horopter surface corresponding to a curved surface when the display panel is a curved surface.
