Solution Overview

Problem

Existing display technologies require an external display screen as a carrier for dual-screen operation, increasing operational complexity and difficulty.

Innovation Solution

A display control method for mobile terminals that allows two distinct display interfaces to operate independently on a single screen, utilizing a foldable or flexible display and different operating systems, with a processor determining the target display area and reporting trigger events to respective desktop launchers to manage the display of applications and interfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an external display screen is used for dual-screen operations, then the display versatility is improved, but the device complexity increases

Engineering Contradiction:
Improvedisplay versatilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mobile terminal's display system is designed to support multiple display modes (fullscreen, freeform, picture-in-picture) and multiple display interfaces (first display interface and second display interface) within a single device, eliminating the need for external display screens while maintaining dual-screen operation capabilities

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent integrates multiple display interfaces and desktop launchers into a single mobile terminal device, combining the functions of what would traditionally require separate external displays into one unified system that can manage multiple display contexts simultaneously

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If multiple display interfaces are managed separately, then the display adaptability is improved, but the ease of operation deteriorates

Engineering Contradiction:
Improvedisplay adaptabilityVSAvoidoperational complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The desktop launcher acts as an intermediary component that receives trigger events from either display interface, determines the target display area, and manages the switching between different display modes and interfaces, simplifying user operations while maintaining display adaptability

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements event-triggered feedback mechanisms where trigger events from user interactions with either display interface automatically initiate the appropriate interface switching and display mode changes, reducing the need for manual configuration and improving ease of operation

Inventive Principle:
Principle #23Feedback

3Area of stationary object

If the second display interface is located over the first display interface, then the space utilization is improved, but the measurement precision of trigger events deteriorates

Engineering Contradiction:
Improvespace utilizationVSAvoidtrigger event precision
Core Design Contradiction:
Area of stationary objectVSMeasurement precision

Solution Approach 1:

The display system is segmented into distinct first and second display interfaces with separate desktop launchers, allowing the system to identify and process trigger events based on their specific origin, thereby maintaining measurement precision even when interfaces are overlaid

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each display interface has its own desktop launcher and event handling mechanism, allowing the system to determine the target display area with precision by identifying which specific interface (first or second) generated the trigger event, even when they are spatially overlaid

Inventive Principle:
Principle #3Local quality

AI summary

A display control method and system, a mobile terminal, and a storage medium are provided. The method includes: acquiring (11) a trigger event, the trigger event including at least one of: an event generated by triggering a first display interface (21) or an event generated by triggering a second display interface (22); acquiring (12) a target display area corresponding to the trigger event; reporting (13) the trigger event to a desktop launcher corresponding to the target display area, so that the desktop launcher starts an interface corresponding to the trigger event in the target display area.
