Support Frame Layout for Thin Display Panel Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices, such as mobile phones, face challenges in reducing thickness due to the separation between the protective window and the display panel, which complicates the support structure and increases overall thickness.
Innovation Solution
A display device with a support frame that includes a guide part and an adhesive member to securely position a protective member relative to the display panel, minimizing the gap between them to a range of 0.2 to 0.6 mm, while maintaining structural integrity and simplicity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the protective window and display panel are separated by at least 1 mm, then the display panel is protected from damage, but the overall thickness of the mobile phone increases
Solution Approach 1:
The support frame integrates multiple functions: it supports the display panel, attaches the protective window, and maintains the protective gap. By merging these separate functions into a single integrated component, the patent eliminates the need for additional separate structures that would increase thickness, while still providing adequate protection.
Solution Approach 2:
The guide part protrudes in a direction perpendicular to the plate surface of the protective member, utilizing the vertical dimension to prevent lateral movement of the protective window. This dimensional approach allows the protective gap to be maintained without increasing the horizontal thickness of the device.
2Length of stationary object
If a support structure is changed to reduce the gap between protective window and display panel, then the overall thickness decreases, but the device becomes more complex and weaker
Solution Approach 1:
The support frame combines the functions of supporting the display panel, attaching the protective window, and maintaining the protective gap into a single integrated structure. This merging reduces device complexity compared to using multiple separate components, while achieving the desired thickness reduction.
Solution Approach 2:
The support frame serves multiple purposes simultaneously: it provides mechanical support for the display panel, attaches the protective window through adhesive members, and maintains the protective gap through its stepped configuration. This multi-functionality reduces the need for additional specialized components.
3Length of stationary object
If the protective member is attached directly to the display panel, then the overall thickness is minimized, but the protective member cannot be securely fixed and may move
Solution Approach 1:
The support frame is designed with a stepped configuration that segments the attachment area into different levels: a first support part for the display panel and a second support part for the protective member. This segmentation allows the protective member to be securely attached while maintaining minimal thickness.
Solution Approach 2:
Adhesive members are introduced as intermediary elements between the support frame and the protective member. These adhesive members provide secure attachment while maintaining a compact thickness, solving the contradiction between secure fixing and minimal thickness.
4Reliability
If adhesive members are used to attach the protective member to the support frame, then the fixing strength is improved, but the manufacturing complexity increases
Solution Approach 1:
Adhesive members serve as intermediary elements that simplify the attachment process between the support frame and protective member. Instead of requiring complex mechanical fastening mechanisms, the adhesive members provide secure attachment through a straightforward bonding process, reducing manufacturing complexity.
Solution Approach 2:
The patent replaces complex mechanical attachment systems with adhesive bonding. This substitution eliminates the need for screws, clips, or other mechanical fasteners, thereby reducing manufacturing complexity while maintaining adequate fixing strength.
