Optical Member Magnifies Display Image Across Non-Display Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large flat panel displays face issues with image discontinuity and distortion at the edges of multiple display panels, leading to quality deterioration and increased costs as display size increases.
Innovation Solution
A multi-panel display device is designed with an optical member that extends from display areas to adjacent non-display areas, using a bundle of optical fibers or sheets to magnify and project the image, and a cover with adjustable polarization characteristics to prevent image discontinuity and enable 3D imaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple display panels are used to create large displays, then display size is increased, but image discontinuity and distortion occur at the edges
Solution Approach 1:
An optical member is introduced as an intermediary component between adjacent display panels. This optical member receives light from the display panels and redirects it to fill the non-display areas, creating a seamless image transition without requiring the panels themselves to directly touch or align perfectly.
Solution Approach 2:
The solution moves the image projection from the 2D plane of the display panel surface to a 3D spatial arrangement by using the optical member to redirect light at angles that project the image across the non-display areas of adjacent panels, effectively adding a dimensional transformation to bridge the gaps.
2Area of stationary object
If display size increases, then more panels are required, but costs and signal delay increase
Solution Approach 1:
The optical member serves multiple functions simultaneously: it fills non-display areas, creates seamless image transitions, and can enable 3D imaging capabilities. This multi-functionality reduces the need for additional specialized components for each function, thereby managing system complexity while achieving large display goals.
3Manufacturing precision
If optical member is added to magnify and project images, then image quality is improved, but device complexity increases
Solution Approach 1:
The optical member is implemented as a thin, flexible component that can be integrated close to the display panel surface. This thin-film approach minimizes the added complexity and space requirements while still providing the necessary optical functions of magnification and image projection.
