Flexible Display Screen Fitting for Narrow-Bezel Curved Covers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with transparent covers and display screens face challenges in achieving a narrow bezel design due to the structural limitations imposed by the sidewall of the frame, which occupies a significant portion of the display area.
Innovation Solution
The use of a flexible display screen with a non-deformable and deformable portion, where the non-deformable portion is fitted to the flat surface of a transparent cover with a curved sidewall, allowing the deformable portion to conform to the sidewall, thereby reducing the frame width and enhancing the display area, along with a fixture device using an elastic rubber head to facilitate the fitting process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a frame with sidewall is used to support the transparent cover and display screen, then the structural integrity is maintained, but the bezel area becomes large and narrow bezel design cannot be realized
Solution Approach 1:
The patent applies a flexible display screen that can be deformed during assembly to fit into a recessed cavity formed by the transparent cover and frame. The flexible nature of the display screen allows it to be compressed into the limited space, eliminating the need for a traditional protruding frame structure and thereby reducing the bezel area while maintaining structural support.
Solution Approach 2:
The display screen is nested within a recessed cavity formed by the transparent cover and frame structure. The flexible display screen is inserted into this cavity and secured at the rear, creating a nested configuration that maximizes the use of internal space and minimizes the external footprint, thus achieving a narrow bezel design.
2Area of stationary object
If the display screen is made flexible to fit the curved sidewall, then the narrow bezel design is achieved, but the manufacturing and assembly complexity increases
Solution Approach 1:
The patent employs a fixture device with an elastic rubber head that is pre-configured with the same curved shape as the display screen. This preliminary preparation of the fixture allows the flexible display screen to be easily formed and positioned during assembly, reducing the actual manufacturing complexity despite the curved geometry requirements.
Solution Approach 2:
The elastic rubber head of the fixture device serves as an intermediary tool that temporarily holds and shapes the flexible display screen during assembly. This intermediary device facilitates the fitting process by providing a pre-formed curved surface that matches the required display screen geometry, making assembly easier despite the complex curved shape requirements.
3Area of stationary object
If the sidewall is designed with curved structure to accommodate the flexible display screen, then the display area is increased, but the manufacturing precision requirements increase
Solution Approach 1:
The fixture device with elastic rubber head is designed to precisely copy or replicate the required curved shape of the display screen and sidewall interface. By using this pre-formed template, the manufacturing precision requirements are transferred to the fixture fabrication process, which can be more easily controlled, rather than requiring high precision in the final assembly of the curved sidewall and flexible display screen.
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
This solution enables a significant reduction in the frame width, thereby achieving a narrow bezel design and increasing the display area without compromising the structural integrity of the device.
Implementation Method 1
applying pressure inside the elastic rubber head, the elastic rubber head driving the flexible display screen to deform to match and fit an inner surface of the transparent cover
Implementation Method 2
the elastic rubber head being configured to deform based on pressure inside the elastic rubber head
Implementation Method 3
a transparent adhesive layer is provided between the flexible display screen and the transparent cover

AI summary
An electronic device includes a transparent cover and a flexible display screen. The transparent cover has a transparent cover having a fixed shape and including a plate-shape flat surface and a sidewall, the sidewall being formed by extending an edge of the flat surface away from the flat surface, the sidewall having a curved structure, and the sidewall and the flat surface forming an inverted structure; and a flexible display screen being fitted to an inner surface of the transparent cover, a display output surface of the flexible display screen facing the transparent cover, the flexible display screen including a non-deformable portion and a deformable portion, the non-deformable portion being fitted to the flat surface, and the deformable portion being fitted to the sidewall.
