Sliding Display Screen for Functional Module Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Full-screen display designs for mobile devices pose challenges in integrating functional modules like front cameras and fingerprint recognition systems without compromising the screen-to-body ratio or aesthetic appeal, as conventional solutions often require placing these components on the back or reducing the screen-to-body ratio.
Innovation Solution
A display device with a first and second display screen covering the device body, where the second display screen is movable to expose or cover functional modules such as camera and fingerprint recognition modules, using a sliding mechanism and flexible display technology to maintain a high screen-to-body ratio and user-friendly design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If functional modules (camera, fingerprint recognition) are placed on the front display area, then user accessibility and functionality are improved, but the screen-to-body ratio and aesthetic appearance deteriorate
Solution Approach 1:
The patent employs a sliding mechanism that allows the second display screen to move dynamically between a first position (covering functional modules) and a second position (exposing functional modules). This dynamic positioning resolves the contradiction by enabling the screen to adapt its state based on operational needs, maintaining high screen-to-body ratio when modules are not in use while providing easy access when needed.
Solution Approach 2:
The patent transitions from a static two-dimensional display layout to a three-dimensional solution by adding the sliding dimension. The second display screen moves along the longitudinal direction, creating a new spatial dimension that allows functional modules to be concealed or exposed without compromising the front display area, thus resolving the area conflict.
2Area of stationary object
If functional modules are placed on the back of the device, then the front display can achieve full-screen coverage, but user accessibility to these modules deteriorates
Solution Approach 1:
The second display screen serves multiple functions: it acts as a display area when positioned at the first location, and as an access window to functional modules when positioned at the second location. This multi-functionality resolves the contradiction by eliminating the need to choose between full-screen display and module accessibility - the same component fulfills both roles at different times.
Solution Approach 2:
The sliding mechanism acts as an intermediary between the display screen and functional modules, enabling controlled access. When the second display screen slides to the second position, it mediates access to the functional modules while maintaining the option to return to the first position for full-screen display, thus resolving the accessibility versus aesthetic contradiction.
3Ease of operation
If a sliding mechanism is added to enable the second display screen to move, then accessibility to functional modules is improved, but device complexity increases
Solution Approach 1:
The patent merges the sliding mechanism with the second display screen structure, making them an integrated assembly. The rail slot and rail are combined with the screen housing, and the fingerprint recognition module is integrated within the same structure. This merging reduces the number of separate components and simplifies the overall structure despite adding sliding functionality.
Solution Approach 2:
The functional modules (camera, fingerprint recognition) are nested within the device body structure, with the second display screen serving as both a protective cover and an access interface. The sliding mechanism is nested within the housing structure, with rail slots and rails integrated into the existing framework. This nesting approach minimizes additional structural complexity while enabling the sliding functionality.

AI summary
A display device includes: a device body; a first display screen; and a second display screen, wherein the device body includes a first region for receiving the first display screen and a second region for receiving the second display screen, and the first display screen and the second display screen collectively cover a surface of the device body, and wherein the second region is provided with at least one functional module, and the second display screen is movable relative to the device body to expose or cover the at least one functional module.
