Mobile Terminal External Display Screen Layout Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals with TV out functions cannot efficiently utilize external display devices due to screen size differences, resulting in empty spaces on the larger screen when displaying images from the mobile terminal, limiting the user's ability to receive a vivid and efficient image.
Innovation Solution
A method and apparatus that allows a mobile terminal to connect with an external display device, transmit content, and control the display position of selected objects, enabling the simultaneous display of current and selected content on the external device, thereby optimizing the use of the larger screen space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the mobile terminal outputs the same image to the external display device, then the user can watch the broadcast through a larger sized screen, but empty spaces are generated on the TV screen due to the difference between screen sizes
Solution Approach 1:
The external display screen is segmented into multiple display regions. The first content (mirrored from mobile terminal) occupies a first display region, while the second content (selected object information) occupies a second display region. This segmentation allows both contents to be displayed simultaneously without empty spaces, resolving the contradiction between large display area and screen utilization efficiency.
Solution Approach 2:
The patent transitions from a single-dimension mirrored display to a multi-dimensional display layout. By dividing the screen into multiple regions and displaying different contents in different regions, the system充分利用 the external display's screen space, eliminating empty spaces while maintaining the mirrored display function.
2Area of stationary object
If the mobile terminal mirrors the entire screen to the external display device, then the broadcast can be viewed on a larger screen, but the user cannot simultaneously view detailed information of selected objects
Solution Approach 1:
The display information is segmented into two parts: the first content (broadcast) and the second content (selected object information). Each part is displayed in a separate display region on the external display device, allowing the user to view both the broadcast and detailed information simultaneously without information loss.
Solution Approach 2:
The patent introduces a mediator mechanism that receives user input about selected objects and transmits this information to the external display device. This mediator function ensures that selected object information is properly integrated into the display output, preventing information loss while maintaining broadcast viewing.
3Device complexity
If the mobile terminal uses traditional mirroring methods, then the connection with external display device is simple, but the screen layout cannot be controlled and empty spaces remain
Solution Approach 1:
The display layout is made dynamic and controllable. The mobile terminal can control the external display device to display content in different regions according to user selection. This dynamic control allows the system to adapt to different viewing needs while maintaining simple connection, resolving the contradiction between connection simplicity and effective display area.

AI summary
Disclosed is a method of controlling a screen display of an external display device by a mobile terminal, including when a connection between the mobile terminal and the external display device is performed, transmitting image data to the external display device and displaying an image displayed in the mobile terminal in the external display device, and when a selection command for one of objects included in the image data is input in the mobile terminal, moving a position of the image displayed in the external display device and then controlling such that the image is displayed together with an image of the object for the selection command.
