Outward Foldable Screen Display Layout for Independent Dual-Screen Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with outward foldable screens fail to utilize both screens effectively after folding, often limiting display to one screen, which restricts the functionality and usability of the device.
Innovation Solution
A display method that allows separate and independent display of information on the first and second screens by using floating icons and non-full-screen windows, with operations like tapping and double-tapping to manage the display of applications and two-dimensional codes on each screen, ensuring that the display on one screen does not interfere with the other.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If only one screen is used for displaying information on an outward foldable screen device, then the device structure remains simple and easy to operate, but the utilization rate of the display screen is low and the functionality is restricted
Solution Approach 1:
The patent divides the display system into two independent display areas (first screen and second screen) that can operate independently. Each screen can display different content and run separate applications, allowing the device to function as two independent displays while maintaining simple operation on each individual screen.
Solution Approach 2:
The patent enables the outward foldable screen to serve multiple functions simultaneously - the first screen can display the home screen with applications while the second screen can display additional information, notifications, or secondary applications. This multi-functionality increases the versatility of the device without complicating the operation of either screen.
2Adaptability or versatility
If both screens are used for displaying information simultaneously on an outward foldable screen device, then the functionality and screen utilization are improved, but the screens may interfere with each other and the system complexity increases
Solution Approach 1:
The patent implements logical segmentation of the display system by creating independent display management for the first screen and second screen. Each screen has its own display controller and can manage its own applications and content independently, reducing system complexity while enabling both screens to function simultaneously.
Solution Approach 2:
The patent applies different display characteristics and management strategies to different parts of the system. The first screen may display full-color high-resolution content while the second screen can display simplified or monochrome content, allowing each screen to be optimized for its specific function while reducing overall system complexity.
3Area of stationary object
If applications are displayed on both screens of an outward foldable screen device, then the screen utilization is maximized, but the display stability and reliability may be compromised due to potential interference between screens
Solution Approach 1:
The patent creates completely independent display pipelines and rendering systems for the first screen and second screen. Each screen's application layer, window manager, and display controller operate independently, eliminating potential interference between screens while maximizing the utilization of both display areas simultaneously.
Solution Approach 2:
The patent introduces a display management intermediary layer that coordinates between the two screens and the system resources. This intermediary ensures that display updates, memory allocation, and processing resources are managed independently for each screen, preventing interference and maintaining display stability while both screens are actively used.

A display method is provided. When an outward foldable screen is in a folded state, Displaying a home screen on a first screen, where the home screen includes a first icon and a second icon of a first application; displaying a first window on the home screen based on a tap operation on the first icon, where the first window includes a first interface of the first application; displaying the first icon on the home screen based on a minimization operation on the first window; displaying the first window on the home screen based on a first operation on the second icon, where the first window includes a first two-dimensional code of the first application; and displaying the first two-dimensional code on the second screen based on a second operation, where the home screen does not include the first window, and the home screen includes the first icon.
