Solution Overview
Problem
Current transparent displays, made with opaque semiconductor compounds, limit their application in fields requiring visibility through the display, necessitating the development of new types of electronic devices with transparent oxide semiconductor layers for enhanced utilization.
Innovation Solution
A display apparatus comprising a transparent display, a scanner with adjustable camera position, and a controller that provides information on the display based on scanned objects, adjusts luminance, chrominance, and transparency, and can translate foreign text, enabling augmented reality functions and improved user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a transparent display is used to allow users to see through it, then transparency is improved, but the ability to display visible information clearly deteriorates
Solution Approach 1:
The display device applies different transparency levels to different regions of the display. The controller selectively controls the transparency of pixel groups based on their function: high transparency for regions where users need to see through (e.g., camera regions, general display areas) and low transparency for regions requiring clear information display (e.g., scanned object information, translation results). This local differentiation resolves the contradiction by allowing both transparency and information visibility to coexist in their respective optimal states.
Solution Approach 2:
The transparency of the display is dynamically adjusted based on the operational context. When the scanner is not in use, the display maintains high transparency for viewing through. When scanning occurs and information needs to be displayed, the controller dynamically reduces transparency in relevant regions to ensure information visibility. This dynamic adjustment allows the system to adapt between the two opposing requirements based on real-time needs.
2Adaptability or versatility
If the scanner is positioned on the front side of the transparent display, then scanning capability is improved, but the aesthetic appearance and transparency deteriorate due to the scanner being visible
Solution Approach 1:
When the scanner is positioned on the front side, the controller captures an image of the scanner itself using the transparent display's camera or sensor, then displays this copied image on the display to replace the physical scanner's appearance. This creates a visual copy that maintains the scanning functionality while hiding the physical scanner, thus preserving aesthetic appearance and transparency when scanning is not actively needed.
Solution Approach 2:
The display acts as an intermediary between the scanner and the user's view. When the scanner is on the front side, the display mediates its visibility by either cropping out the scanner region or displaying a replacement image, thus allowing the scanner to remain in a convenient front-side position for scanning while maintaining aesthetic appearance through the display's optical mediation.
3Illumination intensity
If the scanner is positioned on the rear side of the transparent display, then aesthetic appearance is improved, but scanning precision deteriorates due to limited viewing angle
Solution Approach 1:
The scanner is designed with multi-functionality to operate effectively from the rear side position. It incorporates both a camera for capturing images and a sensor for detecting scanned objects, allowing it to perform scanning functions with adequate precision even when positioned on the rear side for aesthetic purposes. The universal design enables the scanner to maintain functionality despite the compromised viewing angle.
4Loss of information
If transparency of the display is decreased to improve information visibility, then information clarity is improved, but the transparent characteristic deteriorates
Solution Approach 1:
The display applies different transparency levels to different regions based on functional requirements. Regions displaying scanned object information, translations, or other data have reduced transparency for clarity, while other regions maintain high transparency for viewing through. This localized quality differentiation allows the display to provide clear information where needed while preserving the transparent characteristic in other areas.
Solution Approach 2:
The transparency is dynamically adjusted based on the display content and operational state. When information needs to be displayed clearly (during or after scanning), the controller temporarily reduces transparency in relevant regions. When information display is not needed, the display returns to its fully transparent state. This dynamic adjustment allows the system to temporarily sacrifice transparency for information clarity only when necessary.
