Display Ratio Segmentation for Cropping-Free External Screen Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices often struggle to display content with a different display ratio without cropping or requiring multiple displays, leading to incomplete content presentation.
Innovation Solution
A display device that recognizes the content and display ratios, divides the image into areas, and transmits one area to an external device for display extension, allowing seamless integration of the extended image on the surrounding area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the content is displayed according to the display ratio of the display device, then the display fills the entire screen, but a portion of the content is cropped and not displayed
Solution Approach 1:
The patent divides the content image into multiple areas (first area for main content, second area for extended content) and displays them on different display devices. This segmentation allows the entire content to be presented without cropping while utilizing the full display area of the primary display.
Solution Approach 2:
The patent extends the display from a single device to multiple devices, adding a spatial dimension to the display system. By connecting external display devices, the system creates an extended display area that accommodates the full content ratio without losing information.
2Loss of information
If the display device reduces the size of the content to display the entire content, then all content is visible, but the content is displayed in only a partial area of the display with letter-boxing
Solution Approach 1:
The patent segments the content into a first area (main content) and a second area (extended content), displaying them on different display devices. This eliminates the need for letter-boxing while utilizing the full display area of the primary display for the main content.
Solution Approach 2:
By extending the display to external devices, the system adds spatial dimensions to accommodate the full content without reducing its size or adding black borders, thereby utilizing the display area more effectively.
3Loss of information
If the display device connects a plurality of display devices to display the entire content, then the full content is visible, but the device complexity increases
Solution Approach 1:
The patent divides the content into manageable areas (first and second areas) that can be displayed on different devices, simplifying the coordination requirements compared to displaying the entire content on multiple devices.
Solution Approach 2:
The processor acts as an intermediary that manages the content division and distribution between the primary display and external display devices, simplifying the overall system complexity by centralizing the control logic.

AI summary
Provided is a display device including: a display; memory storing one or more instructions; and at least one processor configured to execute the one or more instructions stored in the memory, wherein the one or more instructions, when executed by the at least one processor, cause the display device to: recognize a display ratio of content, generate, based on the recognized display ratio of the content and a display ratio of the display, a first area of an image of the content to be displayed on the display, and a second area of the image of the content to be displayed by an external device on a surrounding area of the display, transmit the second area to the external device, and display the first area on the display while causing the external device to display the second area on the surrounding area of the display.
