Transparent Display Touch-Activated Heater Layer Defrosting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices, particularly transparent displays, face functionality issues in cold or foggy environments due to temperature-related concerns such as frost or condensation, which existing technologies have not adequately addressed.
Innovation Solution
A transparent display system incorporating a touch-sensitive layer and a heater layer with a trace array and electrodes that generate heat upon touch-based input, allowing for localized heating of the display to defrost or defog the window.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a transparent display is used in cold environments, then transparency and visibility are improved, but frost or condensation forms on the display surface reducing functionality
Solution Approach 1:
The heater layer is activated in advance or simultaneously with the transparent display to prevent frost or condensation from forming on the display surface before it can interfere with visibility and functionality
Solution Approach 2:
A heater layer is introduced as an intermediary component between the transparent display and the cold environment to thermally protect the display surface from frost and condensation formation
2Reliability
If a heater layer is added to prevent frost and condensation, then functionality in cold environments is improved, but device complexity increases
Solution Approach 1:
The heater layer serves multiple functions: it prevents frost and condensation formation, and can also provide localized heating in response to touch input, reducing the need for separate heating systems
Solution Approach 2:
The heater layer is integrated with the transparent display structure, combining the heating function with the display assembly rather than requiring a separate, independent heating system
3Use of energy by moving object
If localized heating is activated upon touch input, then energy efficiency is improved, but touch-sensitive control complexity increases
Solution Approach 1:
The transparent display system activates heating automatically in response to touch input without requiring separate control mechanisms, using the touch interface itself to trigger the heating function

Function Achieved in This Case
Ensures the functionality of transparent displays in cold and foggy conditions by effectively defrosting or defogging the display area upon user input, maintaining visibility and usability.
Implementation Method 1
a heater layer connected to the transparent display and including a trace array and one or more electrodes operable to activate the trace array to generate heat to heat at least a portion of the transparent display
Data Source
AI summary
A transparent display system includes a transparent display, a touch-sensitive layer, and a heater layer. The touch-sensitive layer is connected to the transparent display and is configured to detect a touch-based input to the transparent display. The heater layer is connected to the transparent display and includes a trace array and one or more electrodes operable to activate the trace array to generate heat to heat at least a portion of the transparent display based on the touch-based input.
