Flexible Display Screen Extending Retracting Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display screens lack flexibility in accommodating varying display needs and portability, as they cannot efficiently extend or retract to optimize visual experience and power consumption.
Innovation Solution
A flexible display screen with extending and retracting modes, featuring a main display portion and additional display portions that can curl and extend to form different interfaces, supported by slideable brackets and controlled by switching transistors for power management and signal distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display screen is made larger to improve visual experience, then the display area is increased, but the portability and device size are worsened
Solution Approach 1:
The display screen transitions from a static fixed-size configuration to a dynamic reconfigurable configuration. The screen can switch between a compact first configuration for portability and an extended second configuration for enhanced display area, allowing the system to adapt its physical state based on operational needs rather than being constrained to a single fixed dimension
Solution Approach 2:
The display system utilizes spatial reconfiguration by extending the screen in additional dimensions beyond the standard planar layout. The second display portion can be arranged in different spatial configurations (such as folded, extended, or multi-planar arrangements) that effectively increase the usable display area without proportionally increasing the device's footprint when in compact mode
2Area of stationary object
If the entire flexible display screen is used for displaying to improve visual experience, then the display area is maximized, but the power consumption is increased
Solution Approach 1:
The display screen is divided into functionally independent segments: a first display portion and a second display portion. These segments can be independently controlled and activated, allowing the system to power on only the necessary display area for current operational needs rather than illuminating the entire screen, thereby reducing overall power consumption while maintaining adequate visual output
Solution Approach 2:
Different regions of the display screen are assigned different functional qualities and activation states based on local needs. The system can activate high-brightness modes, standard modes, or disabled states in different portions of the screen simultaneously, optimizing power distribution to match the actual display requirements of each local region rather than applying a uniform power level across the entire display
3Adaptability or versatility
If additional display portions are added to extend display area, then the versatility is improved, but the device complexity is increased
Solution Approach 1:
The second display portion serves multiple functions across different operational modes: it can function as an extended display area for additional content, as a support structure to prop the device at viewing angles, or be completely retracted into the device body. This multi-functionality allows a single structural element to provide diverse benefits without requiring separate dedicated components for each function, thereby managing complexity while enhancing versatility
