Display Apparatus Operation State Transmission via Camera Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital signage and display apparatuses without communication systems face challenges in maintenance due to the difficulty in exchanging information with servers, and even those with communication systems face issues when communication fails, making remote monitoring and maintenance costly and inefficient.
Innovation Solution
A display apparatus equipped with an image processor, display, and processor that generates and displays operation state information, including a communicator to send this information to a server, even in the absence of direct communication, using user terminals for proximity detection and marketing information integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a display apparatus does not have a communication system, then the cost of building a communication system is reduced, but maintenance becomes difficult because a person in charge must directly visit the display apparatus to check its state
Solution Approach 1:
The patent introduces a camera as an intermediary device to capture the display screen and transmit images to a remote terminal. This mediator enables maintenance personnel to remotely view the display state without physically visiting the apparatus, thus solving the contradiction between reducing communication system costs and maintaining ease of operation.
Solution Approach 2:
The patent replaces the mechanical/physical system of direct visual inspection with an optical-electronic system using a camera to capture and transmit images. This substitution allows remote monitoring without requiring physical presence at the display apparatus, resolving the contradiction between cost reduction and maintenance accessibility.
2Reliability
If a display apparatus has a communication system, then information can be exchanged with the server, but failure or problems in communication make maintenance difficult like a display apparatus having no communication system
Solution Approach 1:
The patent implements a backup mechanism that activates when the primary communication system fails. The camera-based local display system expands its functionality to become the primary means of information transmission, similar to how thermal expansion allows materials to adapt to temperature changes. This ensures maintenance capability is preserved regardless of communication system status.
Solution Approach 2:
The patent prepares a backup solution (camera-based local display) in advance that can compensate for communication system failures. This prior cushioning ensures that even if the communication system fails, maintenance personnel can still access display information locally, preventing the complete loss of maintenance capability.
3Loss of information
If operation state information is displayed on the display screen, then the information is visible to users, but the content image display area is reduced
Solution Approach 1:
The patent segments the information display function from the content display function. The camera captures only the relevant operation state information from the screen and transmits it to a separate terminal device. This segmentation allows the full display area to be used for content while operation state information is made available through the separate camera-based system.
Solution Approach 2:
The patent moves the operation state information from the two-dimensional display screen to a different dimensional space by capturing it with a camera and transmitting it to an external terminal. This dimensional transition allows the display apparatus to maintain full content display area while still providing access to operation state information through the camera system.

AI summary
Disclosed is a display apparatus that displays an information image and a control method thereof. The display apparatus includes an image processor; a display; and a processor configured to make content be processed by the image processor, make a content image based on the processed content be displayed on the display, generate information about an operation state of the display apparatus, and make an information image containing the generated information about an operation state and recognizable by a user terminal be displayed on the display. With this, the state information of the display apparatus may be effectively transmitted to the server that manages the display apparatus.
