Solution Overview

Problem

Current multi-screen display technologies for mobile officing require users to manually switch applications between terminals, leading to cumbersome processes and poor user experience due to the need for frequent manual control and input device usage.

Innovation Solution

A display method where a first terminal projects applications onto a second terminal by storing and managing display content in screen containers, allowing seamless switching and synchronization of displays through specific gestures, enabling efficient control of both terminals with reduced complexity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the display screen of the mobile phone and the large-screen display independently run their respective display interfaces, then the user can send emails and short messages on the mobile phone and watch movies on the large-screen display simultaneously, but the user needs to control the large-screen display to open applications by using the mobile phone and with assistance of additional input devices, making the process cumbersome and user experience poor

Engineering Contradiction:
Improvemulti-screen display capabilityVSAvoidapplication switching operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent merges the control functions of the mobile phone and large-screen display by allowing the mobile phone to directly control application launching and switching on the large-screen display. The control interface and operation responses are integrated across both screens, eliminating the need for separate input devices and simplifying the user experience while maintaining independent display capabilities.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If the mobile phone projects display content onto the large-screen display using wireless video display function, then the mobile phone can be used as the PC after connecting to the large-screen display, but the process of switching the application between a plurality of screens is cumbersome

Engineering Contradiction:
Improvemobile officing capabilityVSAvoidapplication switching time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent implements preliminary action by pre-establishing the control relationship between the mobile phone and large-screen display through wireless connection. The system prepares the control interface and application environment in advance, allowing users to seamlessly switch between screens without manual configuration or additional setup steps during operation.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If a first terminal sends display data to a second terminal, then the display content can be synchronized between terminals, but the privacy of the first terminal may be compromised

Engineering Contradiction:
Improvedisplay synchronization efficiencyVSAvoidprivacy leakage risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and transmits only the necessary display data from the first terminal to the second terminal, rather than transmitting all terminal information. By selectively sending only the display content that needs to be synchronized, the system maintains display synchronization efficiency while protecting the privacy and security-sensitive information of the first terminal.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

Embodiments of this application provide a display method and an apparatus, and relate to the field of communications technologies, to resolve a technical problem of low efficiency when a terminal switches an application between a plurality of screens to display the application, thereby improving user experience in using the terminal as a PC. The method includes: after a first terminal connects to a second terminal, obtaining, by the first terminal, a first gesture made by a user on a target shortcut in a first display interface, where the first display interface is an interface presented on the first terminal, and target content corresponding to the target shortcut is not running in a foreground of the first terminal; and sending, by the first terminal, first display data to the second terminal based on the first gesture, so that the second terminal displays the first display data in a second display interface, where the first display data is data correlated with the target content, and the second display interface is an interface presented on the second terminal.
