Flexible Display Panel with Movable Frame for Adjustable Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with compact designs face limitations in display area and inflexibility due to the use of rigid liquid crystal display panels requiring backlights, which hinder their ability to meet user visual requirements, especially when functioning as multimedia players.
Innovation Solution
An electronic device featuring a housing with a movable panel-mounting frame, a flexible organic light-emitting display panel, and a torsion spring biasing unit, allowing the display area to be adjusted by extending the panel outward from the device's surface, eliminating the need for a backlight and enhancing display size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a conventional liquid crystal display panel is used, then the device structure is simple and manufacturing is easy, but the display area is limited and the device cannot meet user visual requirements
Solution Approach 1:
The display panel is made flexible and can be extended or retracted along the front wall, transforming from a static fixed-size display to a dynamic adjustable display. The panel mounting frame allows the display panel to move between extended and retracted positions, enabling the display area to be adjusted according to user needs while maintaining a compact device structure.
Solution Approach 2:
The display panel is extended in the horizontal direction along the front wall, adding a dimensional aspect to the display area adjustment. Instead of increasing display area by expanding the device footprint in all directions, the solution utilizes the horizontal dimension along the front wall surface, allowing the display to extend outward and provide larger display area without significantly increasing device volume.
2Volume of moving object
If a rigid liquid crystal display panel with backlight is used, then the display structure is stable, but the device size increases and compact design is hindered
Solution Approach 1:
The patent replaces the rigid liquid crystal display panel with a flexible organic light-emitting display panel. This flexible panel eliminates the need for a separate backlight unit, reducing overall device volume. The flexibility of the panel allows it to be mounted on a movable frame that can extend and retract, providing both compactness when retracted and adequate display area when extended, while maintaining structural stability through proper mounting mechanisms.
3Adaptability or versatility
If the display panel is made flexible and movable, then the display area can be adjusted and enlarged, but the device complexity increases due to additional components
Solution Approach 1:
The movable panel mounting frame serves multiple functions: it provides the mechanical structure for extending and retracting the display panel, acts as a guide for the panel's movement, and integrates with the positioning mechanism. The guide roller not only guides the panel but also works with the positioning unit to lock the panel at specific positions. This multi-functionality reduces the need for separate dedicated components for each function.
Solution Approach 2:
The biasing unit with torsion spring provides automatic biasing force to the display panel, pushing it toward the retracted position. This self-service mechanism eliminates the need for additional actuators or motors to maintain the retracted position, reducing device complexity. The positioning unit works passively with the guide roller to lock positions without requiring active control systems.

AI summary
An electronic device includes a flexible display panel having an intermediate extended display section that interconnects a normal display end section fitted in a panel-mounting frame movable along an outer surface of a housing, and a coupling end section disposed in the housing, that extends through a vertical slot in the housing, and that is guided around a guide roller. The normal display end section of the display panel serves as a normal display area when the panel-mounting frame is positioned at a normal position by a positioning unit. The normal display end section and the intermediate extended display section serve as an enlarged display area when the panel-mounting frame is positioned at an extended position. A biasing unit biases the intermediate extended display section to move into the housing.
