Guide Structure for Curved Display Panel Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During the manufacturing process of display devices with curved windows, the lower portion of the display panel is exposed and prone to damage from external impacts, necessitating a protective measure to prevent damage.
Innovation Solution
A guide structure comprising a guide film with a polymer resin and a cover panel including a cushion layer, heat dissipation layer, and embossing layer is used to apply preliminary pressure to the display panel, ensuring it maintains a predetermined curvature and protecting it from impacts, while a UV light curing adhesive and optically transparent adhesive layers facilitate the attachment of the window.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the display panel is combined with a curved window, then the display device achieves a modern curved design and improved aesthetics, but the lower portion of the display panel becomes exposed and vulnerable to external impacts during the manufacturing process
Solution Approach 1:
A guide structure including a guide film and cover panel is attached to the display panel before the window combination process. The cover panel with cushion layer provides protective cushioning to the lower portion of the display panel during manufacturing, preventing impact damage while allowing the curved window design to be implemented.
Solution Approach 2:
The guide structure acts as an intermediary protective element between the display panel and external impacts during manufacturing. The guide film and cover panel form a temporary protective barrier that shields the display panel lower portion without interfering with the final curved window combination.
2Object-affected harmful factors
If a guide structure with cover panel is used to protect the display panel, then impact protection is provided, but the structural complexity of the manufacturing process increases
Solution Approach 1:
The protective guide structure is divided into separate components: a guide film layer and a cover panel with distinct functional layers (cushion layer, heat dissipation layer, embossing layer). This segmentation allows each component to be optimized independently and facilitates easier attachment and removal during the manufacturing process.
Solution Approach 2:
The guide structure serves multiple functions simultaneously: it provides impact protection through the cushion layer, heat dissipation through the heat dissipation layer, and surface finishing through the embossing layer. This multi-functionality reduces the need for separate protective measures and simplifies the overall manufacturing process despite the added protective capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The guide structure effectively prevents damage to the display panel by applying pressure and providing impact absorption, allowing for successful bending and attachment of the window without exposing the panel to external impacts, thus ensuring the integrity of the display device.
Implementation Method 1
a guide structure including a guide film and a cover panel stacked one over another... applying a preliminary pressure to the display panel by the guide film, such that the display panel has a predetermined curvature
Implementation Method 2
The guide structure may further include an adhesive layer disposed between the guide film and the cover panel, the adhesive layer including a UV light curing adhesive... irradiating the guide film with a UV light before detaching the guide film
Implementation Method 3
an adhesive layer disposed between the polarizing layer and the window, the adhesive layer including an optically transparent adhesive
Implementation Method 4
a cover panel disposed between the guide film and the display panel, the cover panel including a cushion layer
Implementation Method 5
The cover panel may further include a heat dissipation layer disposed between the guide film and the cushion layer... The heat dissipation layer may include at least one of graphite and copper (Cu)
