Foldable Phone Display Segmentation for Selective Mirroring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mirroring technologies in foldable devices do not support multitasking, as they transmit images from the main device to an external device without considering user intent, leading to unwanted pop-ups on the larger screen.
Innovation Solution
A foldable mobile phone with separate displays on the left and right devices, allowing simultaneous display of different images or actions on each screen, with the ability to transmit identical images to an external device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If existing mirroring technology is used to transmit images from the main device to an external device, then image sharing capability is improved, but multitasking capability deteriorates because popup windows and other notifications are also transmitted to the external device, which is not in accord with user intent
Solution Approach 1:
The display system is segmented into multiple independent display regions (first display region and second display region) that can independently control what content is transmitted. This allows selective mirroring where only specific applications or types of content are transmitted to external devices, while keeping notifications and popups localized to the main device, thereby resolving the contradiction between image sharing and multitasking capability
Solution Approach 2:
Different display regions are assigned different functional qualities - the first display region is optimized for content transmission to external devices with selective mirroring, while the second display region handles local notifications and multitasking. This local differentiation allows each region to excel at its specific function without compromising the other
2Adaptability or versatility
If a foldable device displays images on both sides using cameras, then display versatility is improved, but device complexity increases due to the need for multiple cameras and coordination systems
Solution Approach 1:
The foldable display itself is designed to serve multiple functions - it can display content on both sides simultaneously, act as a camera viewfinder, and function as the primary transmission display. This multi-functionality eliminates the need for separate camera display systems, reducing overall device complexity while maintaining display versatility
Solution Approach 2:
The patent merges the camera viewfinder function and the external display transmission function into the same foldable display system. By combining these functions, the device reduces the number of separate components needed while achieving the same or enhanced functionality, thereby reducing device complexity
3Device complexity
If a single display is used for all functions, then device simplicity is maintained, but multitasking capability deteriorates because the same screen must share space between video content and popup windows
Solution Approach 1:
The display is segmented into multiple independent display regions that can operate simultaneously for different functions. One region can display video content while another region handles notifications and popups, enabling true multitasking without requiring a completely complex multi-device architecture
Solution Approach 2:
The patent utilizes the spatial dimension created by the foldable structure to create separate display zones. By folding the display at different angles, the system creates distinct spatial regions that can be independently controlled, adding a dimensional aspect to display management that enhances multitasking while keeping the physical device structure relatively simple

AI summary
The invention relates to a method includes selecting a plurality of call-related icons on a first display in a folded state and switching the mobile phone to an open state, a screen of the second display is divided according to the number of call-related icons selected by the user, and each application corresponding to the selected call-related icon is displayed on the divided second display.
