Electrochromic Layer Segmentation for Local Color Change Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrochromic technologies in electronic devices lack flexibility in color change modes, allowing only the entire electrochromic layer to change color, limiting customization and functionality.
Innovation Solution
The electrochromic device is designed with independent first and second control modules and conductive areas, enabling localized color change and touch control by separating control modules from conductive areas, allowing independent color change and touch sensing in specific areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the entire electrochromic layer is controlled for color change, then the color change function is achieved, but the flexibility of color change mode is insufficient
Solution Approach 1:
The electrochromic device divides the electrochromic layer into multiple independent color change areas (first color change area and second color change area), each controlled by separate control modules. This segmentation allows different regions to change color independently, enabling flexible color change modes such as local pattern display, while maintaining a relatively simple overall control structure.
2Adaptability or versatility
If control modules are separated from conductive areas, then local color change capability is improved, but device structure becomes more complex
Solution Approach 1:
The control modules are separated from the conductive areas and positioned at different locations (first control module and second control module at opposite sides). This spatial segmentation enables independent control of different color change areas, achieving local color change capability while distributing the structural complexity across separate components rather than concentrating it in one complex integrated structure.
Solution Approach 2:
Different regions of the device are assigned different functions: the first control module and first conductive area control the first color change area, while the second control module and second conductive area control the second color change area. This local differentiation of quality and function enables precise local color change control without requiring the entire structure to be complex.
3Ease of operation
If traditional membrane switch technology is used for touch control, then touch sensing is achieved, but power consumption and cost increase
Solution Approach 1:
The electrochromic device integrates touch control functionality into the existing electrochromic structure, allowing the same device to perform both color change and touch sensing functions. This multi-functionality eliminates the need for separate membrane switch components, thereby reducing power consumption and cost while maintaining ease of operation for touch control.
