Laptop Display Hinge Cover Layout for Narrow Bottom Bezels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional notebook computers have wide screen borders due to the space occupied by hinge structures and drive circuits, limiting the maximization of the screen-to-body ratio.
Innovation Solution
A mobile terminal design that includes a display module, host module, and hinge, with a hinge cover overlapping a screen cover plate and screen drive plate, utilizing an FPC connection and adhesive bonding to minimize border width, applicable to both customized and common screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hinge structure and drive circuit are disposed on the display module, then the display module can be driven and connected, but the screen border width increases
Solution Approach 1:
The hinge cover is designed to extend downward from the display module in the vertical dimension, allowing the hinge structure to be positioned below the screen border rather than within it. This dimensional relocation enables the screen border to be narrowed while the hinge remains functional and properly positioned.
Solution Approach 2:
The hinge cover is nested within or integrated with the display module structure, allowing the hinge mechanism to be contained within the overall device footprint without adding to the screen border width. This nesting approach enables compact integration of the hinge while maintaining a narrow border design.
2Area of stationary object
If screen-to-body ratio is improved by narrowing other three borders, then visual perception is enhanced, but the bottom border connected to hinge cannot be narrowed
Solution Approach 1:
By relocating the hinge cover to extend vertically downward from the display module, the design enables the bottom border to be narrowed without compromising hinge functionality. This dimensional repositioning allows all four borders including the bottom to be minimized, thereby maximizing the screen-to-body ratio.
3Length of stationary object
If hinge cover overlaps screen cover plate, then bottom border is narrowed, but structural stability may be compromised
Solution Approach 1:
The hinge cover and screen cover plate are designed with curved or rounded edges at their overlapping interface, creating a smooth transition zone. This curvature design distributes mechanical stresses more evenly across the overlap region, preventing stress concentration and maintaining structural integrity while enabling the narrow border design.
Solution Approach 2:
The hinge cover and screen cover plate are designed as complementary components that work together as a composite structure. The overlapping regions are engineered with interlocking features or adhesive bonding that combines the strengths of both components, ensuring structural stability is maintained despite the reduced border width.

AI summary
A mobile terminal includes a display module, a host module, and a hinge used to connect the display module and the host module. The hinge is disposed on a bottom border of the display module. The display module includes a top cover and a hinge cover that covers the hinge, and the top cover has an accommodating cavity. A screen body, a screen drive plate, and a screen cover plate that covers the screen body are accommodated in the accommodating cavity, and a part of the screen cover plate extends into a cavity of the hinge cover, so that the hinge cover overlaps the part of the screen cover plate. In this technical solution, a width of the bottom border of the display module can be effectively reduced, to facilitate implementation of a narrow border design of the display module.
