Sub Display Extraction of Additional Information From External Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices connected to external devices lack methods for enhancing utility beyond simple screen size extension or duplication, limiting their functionality in displaying additional information relevant to the content.
Innovation Solution
A display device that extracts and updates an additional information area from the pixel data of an external display device's content screen, allowing it to display and manage this information independently based on preset update times, using a processor and communication interface to analyze and control the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a sub display device is connected to an external display device to extend screen size or duplicate content, then the display area is increased, but the utility and functionality for displaying additional relevant information is limited
Solution Approach 1:
The external display device's screen is segmented into a main content area and an additional information area. The processor extracts specific regions from the content screen pixel data and displays them separately on the sub display device, allowing the main screen to focus on primary content while the sub display provides supplementary information.
Solution Approach 2:
The processor extracts additional information areas from the content screen by analyzing pixel data. Specific regions containing relevant information are identified and extracted from the overall content screen, then transmitted to and displayed on the sub display device independently.
2Adaptability or versatility
If additional information is extracted and displayed on a sub display device, then the utility and information relevance are improved, but the device complexity increases
Solution Approach 1:
The external display device's processor performs the extraction and analysis functions autonomously. The processor automatically analyzes content screen pixel data, identifies additional information areas, and transmits them to the sub display device without requiring external intervention or complex external processing systems.
Solution Approach 2:
The processor in the external display device serves multiple functions: displaying the main content screen, analyzing pixel data to extract additional information areas, and transmitting extracted information to the sub display device. This multi-functionality reduces the need for separate dedicated processing components.
3Loss of information
If the additional information area is updated in real-time according to content screen changes, then the information relevance is improved, but the energy consumption and processing load increase
Solution Approach 1:
The sub display device updates the additional information area at preset update time points rather than continuously. The processor controls the display to refresh the extracted information periodically, reducing energy consumption compared to continuous real-time updates while maintaining information relevance.
4Loss of information
If the additional information area is displayed on the sub display device, then the information accessibility is improved, but the simplicity of operation is reduced
Solution Approach 1:
The system automatically extracts and identifies additional information areas from the content screen without requiring manual user configuration. The processor analyzes pixel data and autonomously determines what information to display on the sub display device, eliminating the need for users to manually set up or configure the additional information display.
Data Source
AI summary
A display device incudes memory, a display, a communication interface, and a processor. The processor obtains and stores pixel data of a content screen displayed by an external display device, extracts an additional information area included in the content screen based on the stored pixel data, and displays the extracted additional information area.
