Heating Layer Prevents Condensation in Refrigerated Display Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transparent display modules used in refrigerated electrical equipment face condensation issues due to temperature differences, leading to reduced display effectiveness as cold air enters through gaps and causes water vapor condensation.
Innovation Solution
Incorporating a heating layer between the packaging frame and the transparent display screen, connected to the light emitting component, to heat the air entering through gaps and prevent condensation by maintaining a consistent temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a transparent display module is used in refrigerated electrical equipment, then the display can show articles or structures inside the equipment, but condensation occurs due to temperature differences reducing display effectiveness
Solution Approach 1:
The patent introduces a heating layer that actively changes the temperature parameter of the air between the display screen and packaging frame. By heating this air layer, the temperature difference between the internal and external environments of the display module is reduced, preventing condensation formation and maintaining display effectiveness in refrigerated electrical equipment.
Solution Approach 2:
The heating layer acts as an intermediary element between the cold internal environment of the refrigerated equipment and the warmer external environment. It creates a thermal buffer zone that prevents direct condensation on the display screen, thereby protecting the display effectiveness without requiring changes to the display screen or packaging structure themselves.
2Device complexity
If the heating layer is connected to the light emitting component, then the light emitting component serves dual functions as light source and heating element, but this increases energy consumption
Solution Approach 1:
The patent makes the light emitting component serve dual functions: as a light source for the display and as a heating element to prevent condensation. By connecting the heating layer to the light emitting component, the same component performs both illumination and thermal management functions, reducing the need for separate heating elements and simplifying the overall structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The heating layer effectively prevents condensation within the transparent display module, enhancing its display performance by ensuring that the air entering between the screen and packaging structure is heated, thus eliminating water vapor formation.
Implementation Method 1
a heating layer is between the packaging frame and the display screen... the light emitting component is connected with the heating layer
