Mobile Terminal Case With Virtual Display Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals face limitations in connecting additional display devices without physical connections, particularly when using multi-screen functionality, as they often require hardware coupling or mirror-cast connections, which restricts the ability to manage external displays dynamically.
Innovation Solution
An electronic device with a mobile terminal and a coupled case that allows for screen consecutive viewing and external display management through software control, enabling the generation and removal of external display objects without relying on hardware coupling or mirror-cast connections, using a controller to supply operation power and manage display states based on application requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hardware coupling or mirror-cast connection is used for multi-screen functionality, then connection stability is improved, but adaptability and ease of operation deteriorate due to restrictions on dynamic display management
Solution Approach 1:
The patent creates a virtual display object that copies the functionality of a physical display connection. The controller generates a virtual display interface that mimics the behavior of a physically connected display, allowing the terminal to manage multiple displays through software without requiring corresponding physical connections for each display. This resolves the contradiction by providing adaptability through virtualization while maintaining connection stability through the underlying physical connection to the case's display.
2Adaptability or versatility
If multiple display ports are provided for connecting additional displays, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent makes the case's display serve multiple functions: it acts as both a physical display for the terminal and a virtual display port for additional display connections. The controller manages the case's display to simultaneously support the terminal's output and provide a connection interface for external displays, eliminating the need for separate dedicated display ports on the terminal itself.
Solution Approach 2:
The case's display and controller serve as an intermediary between the terminal and external display devices. Instead of the terminal directly connecting to multiple displays through multiple ports, the case's display acts as a mediator that receives the terminal's output and can simultaneously connect to external displays, reducing the number of required ports on the terminal.
3Reliability
If physical connection release is required to disconnect displays, then connection reliability is improved, but ease of operation deteriorates due to cumbersome connection management
Solution Approach 1:
The patent implements a virtual display connection that copies the reliability of physical connections while adding software-based convenience. The virtual display object maintains a stable connection state managed by the controller, but allows for easy software-controlled disconnection without requiring physical unplugging, thus improving ease of operation while maintaining connection reliability through the stable virtual interface.

AI summary
The present disclosure provides a device having a mobile terminal and a case to which the mobile terminal is coupled. The device comprises the mobile terminal includes: a terminal body coupled to the case; and a first display coupled to the case. The case includes: a first body formed to accommodate part of the terminal body; a second body having a second display; and a wiring portion for electrically connecting the first and second bodies to each other, and through which data received from the mobile terminal is transferred to the second display. And a controller of the mobile terminal provides a signal indicating a usable state of the second display to a relevant application, and supplies an operation power to the second display based on a request signal from the relevant application, if a coupled state of the terminal body to the first body is sensed.
