Flexible Display Bending for Terminal Light Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing design of smartphones with increasing screen sizes is limited by black borders on both sides, which reduce the effective display area and screen ratio, affecting user experience and portability.
Innovation Solution
A terminal design featuring a front glass cover with curved surfaces and a flexible-bendable display screen that covers the front and side surfaces, eliminating the need for a metal middle frame and enhancing the screen ratio by bending the display to cover the sides and overlapping areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If black borders are provided on both sides of the screen to prevent light leakage and enable convenient wiring, then light leakage is prevented and wiring is convenient, but the effective display area and screen ratio are reduced
Solution Approach 1:
The patent extracts the black border structure from the front cover and relocates it to the side surfaces through the curved surface design. The display screen extends onto the side surfaces, eliminating the need for black borders on the front cover while maintaining light leakage prevention functionality through the curved surface geometry and side surface coverage.
Solution Approach 2:
The patent transitions the display area from a two-dimensional plane to a three-dimensional structure by extending the screen onto the side surfaces through curved transitions. This dimensional change allows the display to cover areas that would traditionally require black borders, thereby increasing the effective display area while maintaining structural integrity.
2Reliability
If black borders are provided on both sides of the screen to prevent light leakage and enable convenient wiring, then light leakage is prevented and wiring is convenient, but the screen ratio is reduced
Solution Approach 1:
The black border function is extracted from the front cover area and implemented through the curved surface geometry and side surface extensions. This extraction allows the screen area to expand onto the side surfaces without being constrained by traditional black border limitations, thereby increasing the screen ratio while maintaining light leakage prevention.
Solution Approach 2:
The screen area is extended into the third dimension by wrapping around the curved surfaces and covering the side surfaces of the terminal. This dimensional expansion increases the total screen area relative to the front cover area, thereby improving the screen ratio while maintaining structural integrity and light leakage prevention.
3Strength
If a metal middle frame is used to support the screen structure, then structural strength is provided, but the terminal structure becomes more complex and appearance is compromised
Solution Approach 1:
The metal middle frame is extracted from the structure and replaced by the curved surface geometry of the front cover and the flexible display screen itself. The curved surfaces provide structural support through their geometric form, eliminating the need for additional metal framing components and simplifying the overall terminal structure.
Solution Approach 2:
The flexible display screen and curved glass surfaces serve as thin-film structural elements that provide both support and aesthetic function. These flexible components replace rigid metal frames, reducing structural complexity while maintaining strength through the curved surface geometry and material properties of the flexible display and glass.

AI summary
A terminal includes a front glass cover, a flexible-bendable display screen and a back cover. The front glass cover is formed of glass molding in a unibody, and includes: a front surface area covering a front surface of the terminal; and a first curved surface area, a second curved surface area, a third curved surface area and a fourth curved surface area respectively adjacent to the front surface area and respectively covering four sides of the terminal. The back cover is respectively connected to the first curved surface area, the second curved surface area, the third curved surface area and the fourth curved surface area. The flexible-bendable display screen is attached to an inner surface of the front glass cover, bent to each side surface of the terminal, bent for a second time at overlapping areas of sides of the terminal and covers the four sides and the overlapping areas.
