Display Device Protruding Portion Mounting Area Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The structure around the mounting area in display devices requires enhanced strength to stably support various elements such as light sources, light guides, and frames, which are often compromised due to the complexity and thinness of the array substrate.
Innovation Solution
The implementation of a display device configuration that includes a protruding portion on the first cover member, which attaches to the frame holding the light source unit and light guide, thereby increasing the structural strength around the mounting area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the array substrate is made thin to reduce device complexity, then the overall device structure becomes simpler, but the structural strength around the mounting area deteriorates
Solution Approach 1:
The invention introduces a protruding portion that extends in the thickness direction (third direction) from the array substrate. This dimensional extension provides additional support structure without increasing the planar footprint, thereby maintaining simplicity while enhancing local structural strength around the mounting area.
Solution Approach 2:
The array substrate is divided into a display area and a mounting area, with the protruding portion specifically formed at the mounting area. This segmentation allows the thin substrate to maintain overall simplicity while providing localized structural reinforcement where needed for supporting the light source unit, light guide, and frame.
2Adaptability or versatility
If various elements are provided around the mounting area to enhance functionality, then the device performance is improved, but the structural complexity increases
Solution Approach 1:
The protruding portion serves multiple functions: it provides structural support for the light source unit, light guide, and frame; it enhances adhesion strength for attaching these elements; and it maintains a simple overall structure. This multi-functionality allows various elements to be accommodated without proportionally increasing structural complexity.
