Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transparent electronic monitors, such as non-backlit LCD displays, lack advanced features for dynamic interaction and visualization, limiting their application in advertising, retail, and other environments where attention-grabbing and interactive displays are desired.
Innovation Solution
The integration of a non-backlit liquid crystal display (LCD) with various components like turntables, sensors, switchable LCD films, and central processing units within a display case, allowing for controlled transparency, parallax correction, and interactive content display, enabling the creation of engaging and dynamic visual displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a non-backlit LCD display is used to achieve transparency, then light transmission is improved, but display visibility deteriorates without additional lighting
Solution Approach 1:
The patent combines a non-backlit LCD display with a separate backlight unit and control system into an integrated transparent display apparatus. The LCD display and backlight unit work together as a unified system, allowing the display to maintain transparency while providing sufficient illumination for visible content when activated.
Solution Approach 2:
The patent implements dynamic control of the backlight unit based on environmental conditions and display requirements. The system can switch between transparent and opaque states, and adjust backlight intensity dynamically to optimize both light transmission and display visibility according to viewing conditions.
2Illumination intensity
If a transparent LCD display is used, then transparency is improved, but interaction capability deteriorates
Solution Approach 1:
The patent integrates multiple functions into the transparent display apparatus, including display functionality, touch sensing capability, and interactive control. The system can operate as both a transparent window and an interactive display device, supporting various input methods and application scenarios.
Solution Approach 2:
The patent introduces touch sensors and control systems as intermediary elements between the user and the display content. These intermediaries enable interaction with the transparent display without compromising its transparency, allowing users to input commands and control display content through touch or other input methods.
3Device complexity
If static display content is used, then simplicity is improved, but viewer engagement deteriorates
Solution Approach 1:
The patent implements dynamic display capabilities that allow content to change based on viewer position, movement, and interaction. The system can display different content for different viewers, track viewer engagement, and adjust display parameters in real-time to maintain viewer interest and improve engagement.
Solution Approach 2:
The patent incorporates feedback mechanisms that detect viewer presence, position, and interaction, then use this information to adjust display content and parameters. The system provides real-time feedback to viewers through the display, creating an interactive loop that enhances viewer engagement and maintains attention.

AI summary
A display apparatus includes a transparent electronic display such as a non-backlit LCD screen, a display area disposed behind the transparent electronic display, and a light source for illuminating the display area. When the light source is activated, the pixels of the LCD screen, and objects behind the screen, become visible. Various examples of the display apparatus include additional enhancements to the visual image and/or functionality. These enhancements include additional monitors for coordinated displays, user-controlled turntables with coordinated informational displays, parallax compensation, RFID sensors for identifying objects to be displayed, and switchable liquid crystal films and/or polarized mirror coatings to further control revealing and concealing of objects behind the screen. Some examples of the display apparatus may include an animal habitat. The animal habitat may be selectively revealed or concealed. The display apparatus may incorporate screen displays with animal movements for unique visual effects.
