OLED Display Fastening Structure to Prevent Panel Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face issues with damage to the display panel and local hot-spots due to coupling structures using fastening members, particularly in large-screen, ultra-thin OLED panels.
Innovation Solution
A display device structure that includes a display panel coupled to a plate via a fastening member with a head contacting the plate and a body protruding through it to be fastened to a base, using a screw-like fastening mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a fastening member is used to couple the plate to the base, then the structural stability is improved, but the display panel may be damaged or local hot-spots may occur
Solution Approach 1:
The patent introduces a through-hole as an intermediary structure in the plate, allowing the fastening member to pass through without directly contacting the display panel. This mediator (through-hole) enables the fastening function while protecting the display panel from direct mechanical contact and heat generation, thus resolving the contradiction between structural stability and panel protection.
2Length of moving object
If the display panel is made ultra-thin to achieve ultra-thin display device, then the device thickness is reduced, but the panel becomes more susceptible to damage from coupling structures
Solution Approach 1:
The through-hole acts as a protective intermediary that allows fastening members to pass through the ultra-thin plate without contacting or damaging the display panel. This enables the maintenance of ultra-thin panel design while improving reliability by preventing mechanical damage and hot-spot formation from the fastening structure.
3Strength
If a fastening member with head contacting the plate is used, then the coupling strength is improved, but the risk of damage to the display panel increases
Solution Approach 1:
The fastening member's head is positioned to contact the plate's front surface (not the display panel), while the body passes through the through-hole to fasten to the base. This intermediary arrangement (through-hole) maintains coupling strength through the fastening member while preventing direct contact between the fastening member and the display panel, thus reducing damage risk.
