Display Device Polymer Film Protrusion Through-Hole Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with through-holes face deformation issues due to external pressure, compromising the reliability of components positioned above the through-hole, which affects the quality and durability of the device.
Innovation Solution
A display device design featuring a support member with a through-hole compensated by a polymer film having a protrusion portion that overlaps and contacts the electronic module, along with a light blocking portion to prevent light leakage and enhance structural integrity, using different polymer resins for the protrusion and base portions, and a transparent adhesive for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a through-hole is created in the support member to accommodate the electronic module, then the image displaying area is increased, but the components positioned above the through-hole become susceptible to deformation when pressure is applied
Solution Approach 1:
The protrusion portion is nested within the through-hole of the support member, creating a stepped structure where the protrusion portion fills the void space. This nested configuration provides structural support to components above the through-hole while maintaining the increased display area, thereby resolving the contradiction between area expansion and structural integrity
Solution Approach 2:
The solution transitions from a two-dimensional flat support member to a three-dimensional stepped structure by adding the protrusion portion that extends into the through-hole. This dimensional change creates additional structural support within the vertical dimension, preventing deformation of components while preserving the horizontal display area
2Reliability
If a protrusion portion is added to the polymer film to compensate for the stepped region, then structural integrity is improved, but the device complexity increases
Solution Approach 1:
The protrusion portion is formed from a polymer film, utilizing the flexibility and formability of thin film materials. This allows the creation of the stepped structure with a simple protrusion geometry that compensates for the support member's stepped region without requiring complex multi-component assemblies, thus improving structural integrity while limiting complexity increase
Solution Approach 2:
The polymer film forming the protrusion portion may comprise different materials than the support member, creating a composite structure. This allows optimization of each component's properties while maintaining overall structural integrity, resolving the contradiction between reliability improvement and complexity increase
