Transparent Display Electro-Optical Contrast Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional opaque displays limit the functionality and usability of computing devices, as they cannot provide transparent image viewing and are asymmetrical in image quality from both sides, making it difficult to incorporate ambient backgrounds into images and maintain contrast in bright environments.
Innovation Solution
The development of transparent OLED displays with two see-through substrates and a touch-sensitive interface, allowing for color image quality and see-through capabilities, while mitigating contrast issues through the use of electro-optical materials and counterparts that can switch between black and transparent states, enabling the integration of ambient backgrounds and improved usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional opaque displays are used, then image visibility is ensured, but transparency and ambient background integration are lost
Solution Approach 1:
The display employs electro-optical materials that can dynamically switch between opaque and transparent states based on applied voltage, allowing the display to adapt its transparency level rather than being fixed in one state
Solution Approach 2:
The patent changes the optical parameters of the display by using electro-optical materials whose refractive index and light absorption properties can be modified through electrical control, enabling transition between transparent and opaque states
2Adaptability or versatility
If transparent display materials are used, then transparency is achieved, but image contrast in bright environments deteriorates
Solution Approach 1:
The display system dynamically adjusts between transparent and opaque states to maintain optimal image contrast depending on ambient lighting conditions, using electro-optical materials that respond to electrical signals
Solution Approach 2:
The patent applies preliminary anti-action by using the opaque state to counteract the harmful effect of ambient light overwhelming the display image, thereby preserving image contrast when needed
3Illumination intensity
If opaque elements are included in displays, then image quality is maintained, but see-through capability is lost
Solution Approach 1:
The display uses electro-optical materials that can dynamically transition between opaque and transparent states, allowing the same display structure to provide both high-quality imaging and see-through capability as needed
Solution Approach 2:
The patent achieves multi-functionality by creating a display that can serve both as a traditional opaque display for high-quality images and as a transparent display for see-through applications, using the same electro-optical material layer

AI summary
An apparatus is described. The apparatus includes a transparent display having pixels that appear transparent when in an off mode, and appear as one or more colors when in an on mode. The apparatus also includes a frame surrounding a perimeter of the transparent display. The frame includes non-transparent components that present images on the transparent display. The apparatus additionally includes a connected member that is connected with the transparent display. The connected member provides a contrast to the transparent display when the connected member is positioned opposite a viewing side of the transparent display.
