Flexible Display Panel Retraction for Always-On Screen Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible display devices face challenges in providing an always-on-display mode, require additional mounting space, and are prone to damage due to increased volume and external exposure, failing to meet user demands for larger screens and efficient space utilization.
Innovation Solution
A flexible display device with a module housing, guide rails, a moving plate, and a driving member that allows switching between always-on and normal display modes, minimizing external exposure and reducing damage risk by using a space-efficient design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display device volume is increased to provide a larger screen, then the screen size is improved, but the risk of damage due to external impact increases and the installation space requirement increases
Solution Approach 1:
The display panel is designed to be movable between a retracted position (stored in the housing) and an extended position (exposed for display). This dynamic configuration allows the screen to be large when needed for display while being protected when retracted, resolving the contradiction between screen size and damage risk
Solution Approach 2:
The flexible display panel is nested within the housing structure when not in use, with the panel stored in a compact form inside the housing cavity. This nesting approach allows a large-screen display to be housed in a compact form factor, reducing both damage risk and installation space requirements while maintaining large screen capability when deployed
2Adaptability or versatility
If an always-on-display device is added in addition to a general display device to provide always-on-display mode, then the always-on-display function is improved, but the device complexity and mounting space requirement increase
Solution Approach 1:
The flexible display panel serves multiple functions: it can be extended to provide a full-size display for normal viewing and retracted to provide an always-on-display mode showing only essential information. This single component performs both display modes, eliminating the need for separate always-on-display and general display devices, thereby reducing device complexity and mounting space requirements while maintaining functional versatility
