Display Apparatus Electronic Blackboard Functionality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses require an external device to perform the electronic blackboard function, which is inconvenient for users.
Innovation Solution
A display apparatus with an input unit, storage, and processor that receives images from external sources, performs electronic blackboard functions, and adjusts transparency to synthesize background and input images, enabling autonomous electronic blackboard functionality while displaying external content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display apparatus receives images from external input sources and displays them, then the display function is improved, but the device cannot perform electronic blackboard functions autonomously
Solution Approach 1:
The patent combines the electronic blackboard processing functions with the display apparatus by integrating a processor that can handle both external image inputs and electronic blackboard operations. The processor merges the display control function with the electronic blackboard processing function, allowing the display apparatus to autonomously perform both functions without requiring separate external devices.
Solution Approach 2:
The display apparatus is designed with multi-functionality, where the processor can switch between and simultaneously perform display functions and electronic blackboard functions. The apparatus universally handles various input sources (video signals, audio signals, image data) while maintaining electronic blackboard capabilities including handwriting input, video playback, and screen storage functions.
2Adaptability or versatility
If the display apparatus performs electronic blackboard function on the entire screen, then the electronic blackboard functionality is improved, but external images cannot be displayed simultaneously
Solution Approach 1:
The processor segments the display screen into different regions, allowing external images to be displayed on specific areas while the electronic blackboard function operates on the entire screen or other areas. This spatial segmentation enables both functions to coexist without interfering with each other, maintaining full electronic blackboard functionality while simultaneously displaying external content.
Solution Approach 2:
The patent introduces a transparency dimension to resolve the conflict between full-screen electronic blackboard display and external image display. By adjusting the transparency of the electronic blackboard interface, the system allows external images to be displayed beneath or alongside the blackboard interface, creating a multi-layered display effect that accommodates both functions.
3Ease of operation
If the display apparatus autonomously performs electronic blackboard function, then user convenience is improved, but the device complexity increases
Solution Approach 1:
The display apparatus is equipped with self-service capabilities through an integrated processor that autonomously handles electronic blackboard functions without requiring external control devices. The processor automatically processes handwriting inputs, manages screen displays, controls video playback, and stores screen content, enabling the apparatus to serve itself and eliminate the need for separate electronic blackboard devices.
Data Source
AI summary
A display apparatus and a controlling method of the same are provided. The display apparatus includes: an input unit configured to receive an image from at least one input source; a storage configured to store a program for performing an electronic blackboard function; a display configured to output a screen providing the electronic blackboard function; and a processor configured to control to output, via the display, the received image on at least one area of the screen, and to perform the electronic blackboard function with respect to an entire area of the screen.
