Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing OLED display technologies do not effectively address the need for a flexible display that can be easily adjusted by users to fit their needs, providing a smooth and intuitive user experience.
Innovation Solution
A scrollable display apparatus is designed with a flexible display panel that includes a fixed display part and at least one scrollable display part. The apparatus incorporates detection components to determine the position and state of the scrollable display part, allowing it to display extension display information based on user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display panel with scrollable display part is used to enable free adjustment of display area, then adaptability and ease of operation are improved, but device complexity increases due to the need for detection components and state management mechanisms
Solution Approach 1:
The display panel is divided into a fixed display part and a scrollable display part, allowing independent control and detection of each section. The detection component is segmented into multiple photosensitive elements positioned at different locations to detect the state of the scrollable part at various stages of unfolding.
Solution Approach 2:
The display panel transitions from a static fixed display to a dynamic scrollable display that can be unfolded to different extents. The detection component dynamically detects the state of the scrollable display part as it transitions between folded and unfolded states, enabling real-time adaptation of the display area.
2Measurement precision
If detection components are added to determine the state of the scrollable display part, then control precision is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
Different photosensitive elements are positioned at specific locations corresponding to different unfolding states of the scrollable display part. Each photosensitive element detects light intensity at its local position, and the processor determines the overall state based on the combined information from all elements, achieving precise state detection without requiring a single complex detection mechanism.
3Adaptability or versatility
If the scrollable display part is unfolded to extend display area, then adaptability is improved, but the display apparatus becomes more susceptible to external environmental factors
Solution Approach 1:
The photosensitive elements continuously detect the intensity of external ambient light, and this information is fed back to the processor. The processor uses this feedback to determine the state of the scrollable display part and to control the display output, compensating for the effects of ambient light and enabling accurate state detection even when the display is unfolded and exposed to environmental factors.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables users to freely adjust the display area of the flexible display panel, enhancing user experience by providing a smooth and intuitive interaction with the display apparatus.
Implementation Method 1
at least two photosensitive elements, disposed on the scrollable display part and coupled to the first processor, any photosensitive element being configured to detect an intensity of external ambient light

AI summary
A scrollable display apparatus includes a flexible display panel, at least one first detection component and one or more first processors. The flexible display panel includes a fixed display part and at least one scrollable display part. A first detection component is configured to detect position information of a scrollable display part. The one or more first processors are configured to: determine a current state of the scrollable display part according to the position information of the scrollable display part detected by the first detection component; if it is determined that the scrollable display part is in a start-unfolded state, control the fixed display part to display a plurality of extension selection messages; and in response to a control instruction corresponding to a selected extension selection message, control the scrollable display part to display extension display information corresponding to the selected extension selection message.
