Guide Film with Deformable Corner for Display Panel Impact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses face challenges in effectively reducing external impacts and efficiently manufacturing flexible display panels with rounded corners, where the protective film can easily be damaged, and there is a need for a method to securely attach a cover window while allowing for curvature without obstructing the bending of the display panel.
Innovation Solution
A display apparatus design featuring a display panel with auxiliary display areas on its edges, a cover window, and a guide film with a central area and side areas that connect to form a corner area, allowing for deformation and attachment to the display panel, along with a film adhesive member to secure the guide film, enabling smooth manufacturing and impact absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective film is applied to cover the entire display panel including rounded corners, then the display panel is protected from external impacts, but the protective film may be damaged during bending or curvature formation
Solution Approach 1:
The protective film is divided into multiple regions: a first area that deforms with the rounded corner and a second area that remains flat. This segmentation allows the protective film to accommodate curvature in the corner region while maintaining integrity in the main display area, resolving the contradiction between impact protection and film integrity during bending.
Solution Approach 2:
Different regions of the protective film are assigned different functional qualities: the first area (corner region) is designed to deform and absorb stress during rounding, while the second area (main display area) maintains structural stability. This local differentiation allows the protective film to simultaneously provide impact protection and maintain integrity during curvature formation.
2Ease of manufacture
If the protective film is removed from the corner area to allow rounding, then the display panel can be bent to form rounded corners, but the corner area becomes vulnerable to external impacts
Solution Approach 1:
The first area of the protective film is designed in advance to function as a cushioning region that deforms during corner rounding. This pre-designed deformation capability allows the corner to be formed without removing the protective film, while the deformed first area still provides impact absorption and protection to the underlying display panel corner.
3Strength
If the protective film is made rigid to ensure durability, then the display panel is well-protected, but the manufacturing process becomes complex and time-consuming
Solution Approach 1:
The protective film is designed with dynamic characteristics, allowing it to deform elastically in the first area during corner rounding while maintaining structural rigidity in the second area. This dynamic design enables the protective film to adapt to manufacturing processes like rounded corner formation without requiring complex removal and reapplication procedures, thereby improving manufacturing efficiency while maintaining durability.
