Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern mobile electronic devices with liquid crystal display panels face limitations in display area flexibility and volume reduction due to the inflexibility of these panels and the need for a back light module.
Innovation Solution
An electronic device with a flexible display panel and a detent unit that allows continuous adjustment of the display area, eliminating the need for a back light module by using a flexible OLED panel that can be partially exposed within a window, and a recovering unit to position the panel effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a liquid crystal display panel with back light module is used, then the display area is fixed and stable, but the volume and weight of the device increase
Solution Approach 1:
The patent employs a flexible display panel that can be partially retracted into or extended from the device body, replacing the traditional rigid liquid crystal display panel with back light module. This flexible film structure enables the display area to be adjusted dynamically while reducing the overall device volume and weight, as the display panel can be stored within the device when not fully extended.
Solution Approach 2:
The patent transforms the static display area into a dynamic one by incorporating a retractable mechanism that allows the flexible display panel to be extended or retracted. This dynamic adjustment capability enables the display area to change based on user needs, resolving the contradiction between having a large display area and maintaining a compact device volume.
2Reliability
If a liquid crystal display panel is used, then the display structure is complete and functional, but the weight of the device increases due to the back light module
Solution Approach 1:
The flexible display panel used in this patent is a self-emissive technology that does not require a back light module, thereby significantly reducing the device weight while maintaining display functionality. The flexible film structure itself serves as the complete display solution, eliminating the need for additional back light components.
Solution Approach 2:
The patent extracts and removes the back light module from the display structure, retaining only the essential flexible display panel that can function independently. This extraction of the unnecessary back light component reduces the overall device weight while preserving the core display functionality through the flexible panel's self-emissive capabilities.
3Adaptability or versatility
If the display area is increased to improve video impression, then the display quality improves, but the device volume and weight increase
Solution Approach 1:
The patent implements a dynamic display area that can be adjusted from a retracted state to a fully extended state, allowing the device to provide a large display area when needed for improved video impression, while maintaining a compact volume when the display is retracted. This dynamic adjustment resolves the contradiction between display size and device volume.
Solution Approach 2:
The patent extends the display area in a direction perpendicular to the main device body by using a retractable flexible panel, effectively utilizing three-dimensional space rather than expanding the device volume in all directions. This dimensional approach allows for a larger display area without proportionally increasing the device's overall volume.
4Device complexity
If the display area is fixed to simplify the structure, then the device complexity is reduced, but the adaptability and user experience deteriorate
Solution Approach 1:
The patent incorporates a retractable mechanism with detent positioning that allows the flexible display panel to be extended or retracted with simple user interaction. The detent unit provides automatic positioning at discrete intervals, simplifying the control mechanism while enabling continuous adjustment of the display area, thus maintaining low structural complexity while achieving high adaptability.
Solution Approach 2:
The patent enables continuous adjustment of the display area parameter by allowing the flexible panel to be positioned at various intermediate states between fully retracted and fully extended positions. The detent unit provides stable positioning at different display area sizes, allowing users to adjust the display parameter according to their needs without complex control systems.

AI summary
An electronic device with a display of a continuously adjustable area. The electronic device includes a frame, a flexible display panel, a detent unit and a recovering unit installed in the frame and connected with the display panel. The frame includes a surface and a window formed on the surface. The flexible display panel, longer than the window, is partially exposed in the window and partially within the frame. The detent unit includes two arresting elements established in the flexible display panel and the window separately. The two arresting elements are capable of generating mutual interference. The relative motion between the flexible display panel and the window is not affected when an external force is greater than the interference. Therefore the electronic device has a display with a continuously adjustable area.
