Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a method to conveniently display information on data communications between a mobile terminal and a display device, enhancing user convenience during these interactions.
Innovation Solution
A mobile terminal and display device system that includes a memory unit, display units, and a controller, allowing the mobile terminal to display a first screen image on its own display and control a second screen image on an external display device, enabling simultaneous execution of different software versions between the two devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mobile terminal displays only the first screen image on its own display unit, then the device complexity is low, but the user convenience and information display capability are limited
Solution Approach 1:
The patent combines the display functions of the mobile terminal and external display device into a unified system. The controller integrates screen image generation from different software versions, merging the first screen image (from first version software) and second screen image (from second version software) into a coordinated display system that shows both simultaneously on different display units.
Solution Approach 2:
The controller is designed to perform multiple functions: it generates the first screen image from first version software, generates the second screen image from second version software, transmits the second screen image to the external display device, and coordinates both displays. This multi-functionality enables the system to display multiple software versions simultaneously without requiring separate dedicated hardware for each function.
2Loss of information
If the system displays information on data communications between mobile terminal and display device, then the information availability is improved, but the device complexity increases
Solution Approach 1:
The controller acts as an intermediary that manages the data communication between the mobile terminal and external display device. It receives data from the mobile terminal, generates appropriate screen images based on different software versions, and transmits them to the respective display units. This intermediary role enables comprehensive information display without requiring complex direct communication protocols between all system components.
3Adaptability or versatility
If the mobile terminal connects to external display device for data communications, then the functionality is improved, but the ease of operation decreases
Solution Approach 1:
The system automatically detects the connection status between the mobile terminal and external display device, and autonomously switches between displaying only the first screen image and displaying both first and second screen images simultaneously. This self-service capability eliminates the need for manual configuration or complex user intervention, maintaining ease of operation while enhancing functionality through automatic adaptation to different usage scenarios.
Data Source
AI summary
The mobile terminal has a memory unit configured to store a software, a first display unit configured to display a first screen image generated by a first version of the software, and an interface unit configured to be connected to an external display device having a second display unit. A controller is configured to display the first screen image corresponding to the software of a first version on the first display unit when the software is executed, and to control a second screen image corresponding to the first image, according to the software of a second version to be displayed on the second display unit when the interface unit is connected to the external display device, the second image generated by a second version of the software. Accordingly, a user is able to experience different versions of software simultaneously.
