Transparent Display Panel With Sequential Rotating Rear Plates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices lack the ability to provide a transparent display panel that allows users to see through while also enabling the control of image output in light transmitting or light blocking modes, and a structure for opening or closing the rear side.
Innovation Solution
A display device with a transparent display panel featuring a light emitting region and a transparent region, and a rotatable plate structure that opens or closes the rear side, controlled by a motor and sensor system, allowing for image output control in light transmitting or light blocking modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a transparent display panel is used to allow users to see through, then visibility and transparency are improved, but the ability to control image output in light blocking mode is lost
Solution Approach 1:
The patent applies dynamics by making the display panel's optical properties changeable. The display panel can dynamically switch between transparent and light-blocking states, allowing it to adapt to different usage scenarios. This is achieved through controllable light modulation capabilities that enable the panel to transition between seeing through and displaying images.
Solution Approach 2:
The patent utilizes parameter changes by modifying the optical transmission characteristics of the display panel. By changing parameters such as light transmission intensity and blocking capability, the display panel can switch between transparent and opaque modes, thereby achieving both visibility and image output control in different states.
2Ease of repair
If the rear side of the transparent display panel is opened for component access, then ease of repair is improved, but structural integrity and protection are worsened
Solution Approach 1:
The patent applies segmentation by dividing the rear cover into multiple movable plates that can be independently opened or closed. This segmentation allows selective access to different components without requiring complete disassembly, maintaining structural integrity while providing ease of repair for specific parts.
Solution Approach 2:
The patent uses dynamics by implementing a rotatable plate structure that can dynamically open and close the rear side. The plates are coupled to rotate about rotation axes, enabling controlled access to internal components while maintaining structural strength when closed. This dynamic mechanism balances protection and accessibility.
