Deformable Display Distortion Compensation via Viewer Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bendable or flexible displays can cause distortion in visual information when deformed, leading to undesirable effects such as illegible text or disorienting graphical presentations, which vary based on the viewer's perspective.
Innovation Solution
A display system that includes a deformable display device, a display control unit, and a bend/view position processing system, which generates image control signals to compensate for distortion by considering both the deformation of the display and the viewer's position, using load cells and camera-based viewer orientation detection to adjust the image display data and produce undistorted visuals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display device is made bendable or flexible, then adaptability and versatility are improved, but image distortion occurs when deformed
Solution Approach 1:
The system performs preliminary action by detecting the viewer's position and orientation, and the display's deformation state before rendering the image. This allows the system to pre-calculate the distortion characteristics and apply appropriate compensation to the image data before display, ensuring that the image appears undistorted despite the flexible display's deformation.
Solution Approach 2:
The system implements feedback by continuously monitoring the display's deformation state through sensors and the viewer's position through cameras or other detection devices. This real-time feedback information is used to dynamically adjust the image rendering parameters, allowing the system to compensate for distortion as the display is bent or flexed during use.
2Adaptability or versatility
If the display device is deformed, then adaptability is improved, but text readability and graphical presentation deteriorate
Solution Approach 1:
The system pre-calculates the distortion that will occur based on detected display deformation and viewer position, then applies compensatory transformations to the image data before rendering. This preliminary compensation ensures that text remains readable and graphical presentations remain accurate even when the display is deformed.
Solution Approach 2:
The system changes rendering parameters dynamically based on the detected deformation state and viewer position. By adjusting parameters such as image scaling, rotation, and perspective transformation, the system maintains optimal text readability and graphical quality across different display configurations.
3Manufacturing precision
If distortion compensation is implemented, then image quality is improved, but device complexity increases
Solution Approach 1:
The system achieves universality by using a multi-functional processing unit that can perform both the core display rendering and the additional distortion compensation calculations. By integrating these functions into a single processing pipeline, the system minimizes the need for separate dedicated hardware components, thereby reducing overall device complexity while still providing accurate distortion compensation.
