Solution Overview
Problem
Conventional displays, such as LCDs, lack the ability to seamlessly integrate both information display and mirror functions in a single area, often requiring separate components or methods to achieve these functionalities.
Innovation Solution
An electro-chromic panel with a detection layer and an electro-chromic layer that can switch operational modes based on external signals, allowing for selective generation of transmission and reflective areas, integrated with a display apparatus that includes a readout IC, processor, timing controller, and motion detection sensor to manage these modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a half mirror is attached on a display surface to provide both display and mirror functions, then the display can function as a mirror when OFF and provide image display when ON, but the display area is limited and cannot provide full-area dual functionality
Solution Approach 1:
The display device dynamically changes its optical properties by switching between transparent and reflective states using an electrochromic layer. This allows the same area to serve different functions (display or mirror) at different times, resolving the contradiction between providing dual functionality and maintaining full display area.
Solution Approach 2:
The patent changes the optical parameters (transparency/reflectivity) of the display surface through voltage control of the electrochromic layer. By adjusting these parameters, the display can transition between display mode and mirror mode, enabling full-area dual functionality without sacrificing display area.
2Adaptability or versatility
If separate components are used for display and mirror functions, then both functions can be provided, but the device complexity increases
Solution Approach 1:
The patent merges the display function and mirror function into a single integrated device. The electrochromic panel combines the display panel with electrochromic layers, allowing both functions to be provided by one component rather than separate devices, thus reducing overall system complexity.
Solution Approach 2:
The display device is designed to perform multiple functions (display and mirror) through a single unified structure. The electrochromic layer enables the same surface to serve different purposes based on operational mode, eliminating the need for separate mirror components.
3Area of stationary object
If the entire display area is used for mirror function when OFF, then full mirror coverage is achieved, but the transition to display mode requires complete coverage loss
Solution Approach 1:
The display device is divided into independently controllable regions, each with its own electrochromic layer. This segmentation allows different areas to be switched between transparent and reflective states independently, enabling flexible mode transitions and partial mirror/display configurations.
Solution Approach 2:
Different regions of the display can have different optical properties simultaneously. Some areas can be transparent for display while others remain reflective for mirror function, allowing localized quality variation to meet different functional requirements within the same device.
