Vacuum Glass Display Structure for Heat-Insulated Durability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices lack durability and effective thermal insulation, particularly in movable objects where exposure to varying environmental conditions can lead to damage and reduced performance.
Innovation Solution
Incorporating a glass panel unit with a pressure-reduced internal space between the glass pane and the display panel, which reduces heat transfer and protects the display panel from external heat, while using strengthened glass for the glass pane and panel to enhance durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional display device structure is used, then the device is simple and easy to manufacture, but the durability and thermal insulation properties are insufficient
Solution Approach 1:
The patent implements a nested structure where the display panel is positioned within a cavity formed by the glass pane, creating a protective enclosure. The glass pane surrounds and protects the display panel, forming a nested configuration that enhances durability while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent divides the structure into distinct functional components: a glass pane providing protection and thermal insulation, and a display panel providing visual output. This segmentation allows each component to be optimized independently for its specific function while contributing to overall system reliability.
2Temperature
If a conventional display device structure is used, then the device structure is simple, but the thermal insulation properties are insufficient
Solution Approach 1:
The glass pane serves as an intermediary element between the external environment and the display panel. It provides thermal insulation by creating a physical barrier that reduces heat transfer to the display panel, while also offering mechanical protection. This intermediary structure effectively isolates the display panel from thermal extremes.
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 solution improves the durability and thermal insulation of the display device, allowing it to maintain visibility and functionality in varying environmental conditions while protecting internal components.
Implementation Method 1
the glass panel unit has an internal space which is in a pressure-reduced condition... reduces heat transfer and protects the display panel from external heat
