Integrated Frame Design for Lightweight Display with Dust Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid crystal display apparatuses with glass bonding techniques require a large number of components for dust and water resistance, which hinders the development of lightweight designs due to the need for extensive framing, leading to material inefficiencies and potential issues with light leakage and display quality.
Innovation Solution
A display apparatus design featuring a frame that holds the display module with a transparent member on the display surface, where the frame's side surface is fixed to the display module's side surface using a joining member, eliminating the need for an undersurface extension and reducing material usage while maintaining dust and water resistance through adhesive materials and a fixing structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the housing includes many members (side surface portion and undersurface portion) to hold the touch panel, then dust resistance and water resistance are improved, but the weight and material usage increase
Solution Approach 1:
The patent merges the side surface portion and undersurface portion of the housing into a single integrated frame structure. The frame holds both the display panel and touch panel while providing dust and water resistance through its unified design, eliminating the need for separate housing members and reducing overall material usage.
Solution Approach 2:
The frame serves multiple functions simultaneously: it holds the display panel, holds the touch panel, provides dust resistance, and provides water resistance. This multi-functional design replaces the need for separate specialized components, reducing the total number of parts while maintaining all necessary protective functions.

3Strength
If the frame uses extensive material to hold the display module, then structural strength is improved, but weight and material efficiency deteriorate
Solution Approach 1:
The frame is designed with distinct functional regions: a first frame portion that holds the display panel and a second frame portion that holds the touch panel. This segmentation allows each portion to be optimized for its specific function with appropriate material usage, avoiding excessive material in areas where less is needed while maintaining overall structural strength.
Solution Approach 2:
The frame employs local quality by providing different structural characteristics in different regions. The first frame portion has structural features optimized for holding the display panel, while the second frame portion has features optimized for holding the touch panel. This localized optimization ensures strength where needed while reducing material usage where full strength is not required.

AI summary
A display apparatus includes a frame that holds a display module. The display module includes a protective member located on a display surface side of a display panel. The frame has a plane surface opposed to a periphery of the protective member and a side surface opposed to a side surface of the display module. The plane surface of the frame is fixed to the periphery of the protective member through a joining member. The display apparatus has a fixing structure to fix the side surface of the frame to the side surface of the display module.
