Image Transport Layer for Curved Display Distortion Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with displays often suffer from bulkiness, unattractiveness, and distortion of images due to their design, making them difficult to use and view effectively, especially when displaying curved surfaces or compound curvature configurations.
Innovation Solution
The integration of an image transport layer, such as a coherent fiber bundle or Anderson localization material, which conveys light from a planar display surface to a curved output surface, combined with an adjustable opacity layer and diffusive material to enhance viewing angles and reduce ambient light reflections, and image distortion control circuitry to modify pixel data for optimal perceived distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a planar display panel is used, then manufacturing is simple, but the display appears bulky and unattractive
Solution Approach 1:
The display system is segmented into distinct functional layers: a planar display panel, an image transport layer, and a curved output surface. This segmentation allows each layer to perform its specific function optimally while achieving the overall curved display effect, resolving the contradiction between simple manufacturing and attractive shape.
Solution Approach 2:
An image transport layer acts as an intermediary between the planar display panel and the curved output surface. This intermediary component transfers light from the flat panel to the curved surface, enabling the display to achieve an attractive curved shape without requiring the entire display structure to be complex and curved.
2Shape
If light is conveyed to a curved surface, then the display is attractive and borderless, but image distortion occurs
Solution Approach 1:
Image distortion control circuitry performs preliminary processing on the image data before it reaches the display panel. By pre-distorting the image in the opposite direction of the expected curvature-induced distortion, the system compensates for distortion effects, ensuring that the final displayed image appears correct to the viewer.
Solution Approach 2:
The system incorporates feedback mechanisms where sensor data about the display configuration and viewing conditions is used to dynamically adjust image processing parameters. This feedback loop enables real-time compensation for distortion, maintaining image precision across the curved display surface.
3Adaptability or versatility
If the display surface is curved, then the display is viewed from various angles, but ambient light reflections increase
Solution Approach 1:
An adjustable opacity layer is positioned between the curved output surface and the viewer. This layer can dynamically change its optical properties (transparency/opacity) to adapt to ambient lighting conditions. When ambient light is high, the layer becomes more opaque to reduce reflections; when ambient light is low, it becomes more transparent to maintain viewing quality, thus resolving the contradiction between wide viewing angles and reflection control.

AI summary
An electronic device may have a display panel for displaying images. A display cover layer having curved portions may overlap the display panel. An image transport layer having an input surface that receives light from the display panel may convey the light from the input surface to an output surface adjacent to an inner surface of the display cover layer. The image transport layer may include fibers with different lengths to form a region of the output surface with a curved profile. Each fiber in the coherent fiber bundle may have a respective output face. The output face of each fiber in the curved edge region of the image transport layer may be parallel to the display panel or may be angled towards the center of the image transport layer. Image distortion control circuitry may modify image data to control the perceived distortion of the display.
