Mobile Terminal Screen Space Optimization via TV-Out Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals with TV-out functions face inefficiencies in utilizing screen space and power consumption when displaying images on a larger screen, as they either switch off the screen or replicate the image, preventing additional information display and convenient user interaction.
Innovation Solution
A method and mobile terminal design that allows the mobile terminal's screen to display an image control window and supplementary information while transmitting the image to a separate display apparatus via a TV-out cable, enabling efficient use of screen space and power by maintaining the image control window and displaying supplementary info on the mobile terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the mobile terminal displays the same image as the television while using TV-out function, then the user can watch the image on a larger screen, but the screen space of the mobile terminal cannot efficiently be utilized to provide the user with further information and convenience
Solution Approach 1:
The patent divides the display content into two separate parts: the main image displayed on the television screen and supplementary information displayed on the mobile terminal screen. This segmentation allows each display device to serve a specific function - the TV provides the primary visual content while the mobile terminal provides control interfaces and additional information, thereby resolving the contradiction between utilizing large display area and providing convenient operation.
2Area of stationary object
If the mobile terminal displays the same image as the television while using TV-out function, then the user can watch the image on a larger screen, but the mobile terminal consumes its limited source of electric power to display the same image
Solution Approach 1:
The patent extracts the function of displaying the main image from the mobile terminal and relocates it to the television display. The mobile terminal retains only the essential function of providing control interfaces and supplementary information, which requires minimal power consumption. This extraction resolves the contradiction by eliminating redundant power-consuming operations while maintaining the benefit of large-screen display.
3Use of energy by moving object
If the screen of the mobile terminal is switched off while using TV-out function, then power consumption is reduced, but the screen space of the mobile terminal cannot efficiently be utilized to provide the user with further information and convenience
Solution Approach 1:
The patent applies local quality by selectively activating only the necessary portions of the mobile terminal screen - specifically the image control window and supplementary information display areas - while keeping the rest of the screen inactive or minimally active. This approach allows the terminal to provide essential control functions and information with minimal power consumption, resolving the contradiction between power savings and operational convenience.

AI summary
The present invention provides a mobile terminal and a method of displaying an image using the same. A method of displaying an image includes connecting a mobile terminal displaying an image on a screen to a display apparatus through a TV-out cable; terminating the display of the image on the screen by the mobile terminal and displaying supplementary information of the image on the mobile terminal; and displaying the image in the display apparatus by transmitting the image from the mobile terminal to the display apparatus through the TV-out cable. By utilizing a display apparatus for displaying an image, and a display screen of a mobile terminal as a space for controlling the image and displaying supplementary information of the image file, the convenience of a user of the mobile terminal is improved.
