Display Device Substrate Segmentation for Thin Profile Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices lack a design that allows for a display panel to be exposed to the outside while maintaining a thin profile and rigidity structure.
Innovation Solution
A display device comprising a first substrate, a frame positioned in the rear, a second substrate opposite the first substrate with a smaller area, and a member layer electrically connected to the first substrate, extending toward the frame, which allows the display panel to be exposed to the outside while maintaining structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the display panel is exposed to the outside, then the aesthetic appearance and viewing angle are improved, but the structural rigidity and protection are worsened
Solution Approach 1:
The display device is divided into multiple substrates (first substrate, second substrate, third substrate) with different areas and functions. The first substrate has a larger area for structural support, while the second substrate has a smaller area for display functionality, allowing the display panel to be exposed while maintaining rigidity through the segmented structure.
2Length of moving object
If the display device is made thinner, then the portability and aesthetics are improved, but the structural stability and rigidity are worsened
Solution Approach 1:
The patent introduces a multi-layer substrate structure extending in multiple dimensions. The first substrate extends in a first direction, the second substrate extends in a second direction, and the third substrate extends in a third direction, creating a three-dimensional rigid structure that maintains stability while keeping the overall device thin.
3Reliability
If the member layer is extended toward the frame, then the electrical connection is improved, but the device complexity is worsened
Solution Approach 1:
The member layer serves multiple functions: it provides electrical connection between substrates, acts as a structural support element, and extends toward the frame to integrate different components. This multi-functionality reduces the need for separate connection structures, thereby managing complexity while improving reliability.
