Flexible Display Portable Terminal Hinge Angle Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable terminals lack the ability to display images of varying sizes effectively, as their fixed display formats restrict flexibility and user experience.
Innovation Solution
A portable terminal design featuring a flexible display panel housed within two rotating housings connected by a hinge, allowing the terminal to be folded at various angles, with a driver system that adjusts the display area and output signals to match the angle, enabling the display of images of different sizes on the exposed portion of the flexible display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed display format is used in conventional portable terminals, then the device structure is simple, but the ability to display images of varying sizes is limited
Solution Approach 1:
The patent implements a dynamic display system where the flexible display panel can be unfolded to different extents, allowing the display area to dynamically change from a compact state to an expanded state. This enables the terminal to adapt to different display size requirements while maintaining a relatively simple base structure.
Solution Approach 2:
The driver detects the unfolding angle of the flexible display and dynamically adjusts display parameters including the active display area, resolution, and refresh rate based on the detected angle. This allows the system to optimize display performance for different unfolding states without requiring multiple fixed display configurations.
2Adaptability or versatility
If the flexible display is unfolded to various angles, then images of various sizes can be displayed, but the control complexity increases
Solution Approach 1:
The driver includes an angle sensor that continuously detects the unfolding angle of the flexible display and provides feedback to the control system. Based on this feedback, the driver automatically adjusts the display parameters and active area, eliminating the need for manual intervention and simplifying the user interaction while maintaining high adaptability.
Solution Approach 2:
The display system is designed to automatically determine its own configuration based on the detected unfolding angle. The driver self-adjusts the display area and parameters without requiring external control signals for each angle change, making the system self-configuring and reducing overall control complexity.
3Area of stationary object
If the display area is increased by unfolding, then more image information can be shown, but the portability is reduced
Solution Approach 1:
The flexible display is divided into multiple sections that can be folded or unfolded relative to each other. When portability is needed, the display folds into a compact configuration; when display area is needed, the display unfolds to reveal additional screen real estate. This segmentation allows the same display to serve both portability and large-screen needs.
Solution Approach 2:
The flexible display structure allows one portion of the display to be nested within or alongside another portion when folded, creating a compact form factor for portability. When unfolded, the nested portions expand to provide a larger display area, effectively allowing the display to transform between compact and expanded states like nested dolls.
