Transparent Display with Scanning Lens Array
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies, such as those using non-transparent semiconductor compounds, limit user interaction and information retrieval by not allowing simultaneous viewing of objects behind the display and the display screen, necessitating the development of a transparent display apparatus that can enhance spatial and temporal usage.
Innovation Solution
A display apparatus incorporating a transparent display with a scanner featuring a lens array and a controller that scans objects viewed through the display, providing information related to the scanned objects, and adjusting transparency for improved visibility, including translation of foreign text and graphical user interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If non-transparent semiconductor compounds are used in manufacturing a display panel, then the display screen can be manufactured with conventional materials, but users cannot view objects behind the display simultaneously
Solution Approach 1:
The patent changes the optical parameter (transparency) of the display panel by using transparent oxide semiconductor layers instead of conventional non-transparent materials like Si or GaAs. This material substitution enables light transmission through the display, allowing users to simultaneously view the display screen and objects behind it, thus resolving the contradiction between manufacturability and simultaneous viewing capability.
2Adaptability or versatility
If a transparent display is used, then users can view both the screen and real objects behind the apparatus, but the display transparency must be adjusted to ensure information visibility
Solution Approach 1:
The patent implements dynamic transparency control where the transparent display can adjust its transparency level based on operational modes. The display transitions between different transparency states (more transparent when scanning is needed, less transparent when display visibility is prioritized), allowing the system to adapt to different usage scenarios without requiring permanently fixed transparency, thus managing the complexity through intelligent control rather than hardware complexity.
3Device complexity
If the lens array is positioned close to the transparent display, then the scanning function can be integrated compactly, but the lens array may interfere with the transparency and viewing experience
Solution Approach 1:
The patent positions the lens array in a different spatial dimension relative to the transparent display, specifically arranging it at an angle or in a configuration that allows scanning functionality without blocking the user's line of sight to objects behind the display. This dimensional arrangement enables both the integrated scanning function and maintains the transparency viewing experience simultaneously.

AI summary
A display apparatus is disclosed. The display apparatus includes: a transparent display, a scanner comprising a lens array and attached to the transparent display and a controller configured to control the scanner to scan an object viewed through the transparent display using the lens array being slid from a side of the transparent display to another side opposite to the side, and control the transparent display to display information in response to the scanning of the object.
