Display Screen Assembly with Decoration Enclosure Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smartphones have a low screen-to-body ratio, which negatively impacts user experience due to the presence of a black-ink edge around the display screen.
Innovation Solution
A display screen assembly that integrates a touch-screen cover plate with a trapezoidal cross-section and a decoration enclosure with an arc-shaped outer surface, eliminating the need for a black-ink edge by using a second joining part to shield the non-display area, thereby increasing the screen-to-body ratio and enhancing waterproof performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a black-ink edge is used to shield the non-display area, then the display screen is protected, but the screen-to-body ratio decreases
Solution Approach 1:
The patent extracts the shielding function from the traditional black-ink edge and relocates it to a decoration enclosure component. The decoration enclosure's second joining part is specifically designed to shield the non-display area, separating the shielding function from the display area to enable full-screen display while maintaining protection.
Solution Approach 2:
The solution transitions from a two-dimensional black-ink edge on the display surface to a three-dimensional decoration enclosure structure that extends vertically. The decoration enclosure with its specific height and positioning provides shielding functionality without occupying display area, effectively using spatial dimensionality to resolve the contradiction.
2Strength
If a traditional frame structure is used, then structural support is provided, but the outer surface smoothness deteriorates
Solution Approach 1:
The patent merges the frame structure with the decoration enclosure into a unified component. The decoration enclosure integrates both the structural support function (replacing traditional frame) and the aesthetic outer surface function, eliminating the need for separate frame and cover plate structures and achieving a seamless smooth outer surface.
Solution Approach 2:
The decoration enclosure serves multiple functions simultaneously: it provides structural support (replacing frame), shields the non-display area, and forms the outer surface of the device. This multi-functional design eliminates the need for separate components and achieves both structural integrity and surface smoothness.
3Adaptability or versatility
If multiple separate components are used for assembly, then manufacturing flexibility is improved, but assembly complexity increases
Solution Approach 1:
The patent combines multiple traditional components (frame, cover plate, shielding structure) into a single integrated decoration enclosure. This integration reduces the number of parts and assembly steps while maintaining manufacturing flexibility through modular design of the decoration enclosure itself, which can be manufactured using various processes.

AI summary
The present disclosure relates to a display screen assembly, an electronic device and an assembling method of the display screen assembly. The display screen assembly includes a cover plate, a display screen, a bracket and a decoration enclosure. A top surface of the display screen is joined with a lower surface of the cover plate, a width of the display screen is larger than that of the cover plate, and a side edge of the cover plate is indented inwards relative to the display screen. The bracket includes a top portion joined with a bottom surface of the display screen and a side wall. The decoration enclosure includes a first joining part joined with the side wall and a second joining part. The second joining part is joined with the side edge of the cover plate and configured to cover a non-display area of the display screen.
