Display Apparatus Mirroring Screen Conversion via Touch Icons
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses face difficulties in converting a mirroring screen into an image provided from a display apparatus, especially when a separate hard key is not available, making it challenging to control the mirroring screen effectively.
Innovation Solution
A display apparatus and controlling method that receive an image from an external terminal apparatus, display it as an entire screen, and provide screen converting icons to allow users to switch between images from the display apparatus and the terminal apparatus, enabling convenient conversion and control through touch manipulations and menu icons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the entire display screen is used to show the mirroring screen from the terminal apparatus, then the display area for mirroring is maximized, but the user cannot conveniently convert to images provided from the display apparatus without separate hard keys
Solution Approach 1:
The display screen is segmented into two functional regions: a large area for displaying the mirroring screen from the terminal apparatus, and a separate region for displaying control icons (including screen converting icons and menu icons). This segmentation allows the mirroring function to occupy maximum display area while providing dedicated control elements for easy operation.
Solution Approach 2:
Icons serving as intermediaries are introduced on the display screen to enable screen conversion without requiring physical hard keys. The screen converting icon and menu icons act as visual mediators that users can touch to switch between mirroring mode and image display mode, replacing the need for separate hardware buttons.
2Device complexity
If separate hard keys are not provided in the display apparatus, then the device structure is simplified, but it becomes difficult to convert the mirroring screen into an image from the display apparatus
Solution Approach 1:
The mechanical hard key system is replaced with a touch-based icon system. Instead of requiring physical buttons on the device, the display screen presents visual icons (screen converting icon, menu icons) that users can interact with through touch input, enabling the same functionality with a simpler, more integrated structure.
3Area of stationary object
If the display screen shows only the mirroring screen, then the user can view the terminal apparatus screen fully, but the user cannot access menu functions or convert screens without additional keys
Solution Approach 1:
The display screen serves multiple functions simultaneously: it displays the mirroring screen from the terminal apparatus, presents screen converting icons for mode switching, and displays menu icons for accessing various functions. This multi-functionality is achieved by overlaying control elements on the display without reducing the mirroring display area, allowing users to access diverse functions through a single integrated interface.

AI summary
A controlling method of a display apparatus includes: receiving an image displayed on an external terminal apparatus from the external terminal apparatus; displaying the received image in an entire region of a display screen; displaying at least one screen converting icon on the display screen; and displaying an image provided from the display apparatus on the display screen when a touch manipulation is input to the screen converting icon.
