Variable Pulling Speed Control for Flexible Scroll Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The constant pulling speed of scroll displays in electronic devices, such as laptops, results in a poor user experience due to inadequate adaptation to varying target angles between the base and screen sections.
Innovation Solution
A control method and apparatus that dynamically control the pulling speed of a flexible display's first member based on the target angle between the first and second bodies of an electronic device, utilizing an angle acquisition unit and speed control unit to adjust the speed according to different angle ranges, thereby optimizing the user experience by varying the speed based on the angle.

Engineering Contradiction Analysis
1Ease of operation
If the pulling speed of the scroll display is kept constant, then the structure is simple, but the user experience is poor due to inadequate adaptation to varying target angles
Solution Approach 1:
The patent applies dynamics by transitioning from a constant pulling speed to a variable pulling speed that adapts to different target angles. The control structure dynamically adjusts the pulling speed based on real-time angle detection, making the system responsive to changing operational conditions and improving user experience without excessive complexity
Solution Approach 2:
The patent changes the parameter of pulling speed from a fixed value to a variable that depends on the target angle. By establishing a correspondence between different angle ranges and different pulling speeds, the system optimizes performance for various operational scenarios while maintaining a relatively simple control architecture
2Productivity
If the pulling speed is increased for faster expansion, then productivity improves, but the control precision deteriorates when adapting to different angle ranges
Solution Approach 1:
The patent employs parameter changes by establishing a multi-level speed control system where different pulling speeds are selected based on target angle ranges. This allows the system to achieve high productivity when fast expansion is needed while maintaining precise control when operating in specific angle ranges, effectively balancing speed and precision requirements

AI summary
A control method includes obtaining a target angle between a first body and a second body of an electronic device and controlling a pulling speed of the first member at least according to the target angle. A flexible display includes a first member and a second member. The first member is arranged in the first body to be hidden by the first body. The second member is arranged at the second body to output content on the second body. The first member is able to be pulled, by a power structure of the electronic device, from the first body to the second body or from the second body back to the first body.
