Wireless Communication Modules Behind Display Panel for Contact-Free Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic whiteboards and displays lack a convenient and secure authorization and authentication mechanism, requiring manual input of credentials and being vulnerable to unauthorized access, which leads to data leakage.
Innovation Solution
A display apparatus with wireless communication modules, such as NFC or RFID, disposed behind the display panel to communicate with a wireless communication apparatus in front, using a penetrating electromagnetic signal to provide contact-free authorization and authentication, allowing secure access to displayed content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual input of authorization data is required, then security is maintained through user control, but ease of operation deteriorates due to inconvenience
Solution Approach 1:
The patent replaces the mechanical manual input system with a wireless electromagnetic communication system. NFC/RFID modules communicate authorization data wirelessly through the display panel, eliminating the need for manual keyboard or touchscreen input while maintaining security through automated authentication protocols
Solution Approach 2:
The display panel itself serves as an intermediary medium. Wireless communication modules positioned behind the panel communicate with external devices through the panel, which acts as a mediator that enables contactless authorization while maintaining system security and user control
2Reliability
If no authorization mechanism is implemented, then ease of operation is improved through unrestricted access, but data security deteriorates due to vulnerability to unauthorized access
Solution Approach 1:
The display panel serves multiple functions: it displays visual content and simultaneously acts as a communication medium for wireless authorization. The NFC/RFID modules integrated behind the panel provide both display functionality and security authentication, reducing overall system complexity while enhancing data protection
Solution Approach 2:
The patent merges the display function and authorization function into a single integrated system. The wireless communication modules are positioned behind the display panel, combining what were previously separate components into one unified structure that provides both visual output and security authentication
3Ease of operation
If wireless communication modules are disposed behind the display panel, then ease of operation is improved through contact-free authorization, but device complexity increases due to additional components
Solution Approach 1:
The wireless communication modules are nested behind the display panel, with the NFC/RFID components positioned in the rear layer of the display structure. This nesting arrangement allows contactless authorization through the panel while integrating the additional components into the existing display architecture, minimizing the increase in device complexity

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables a convenient and secure authorization process by obtaining and processing authentication data through electromagnetic communication, enhancing user experience and protecting displayed data from unauthorized access.
Implementation Method 1
each of the at least one first wireless communication module is operated at a working frequency capable of penetrating through the display panel to communicate with the wireless communication apparatus in front of the display panel
Data Source
AI summary
A display apparatus and an authorizing method thereof are provided. The display apparatus includes a display panel and at least one wireless communication module disposed behind the display panel. In the method, a frame is displayed on the display panel, and the at least one wireless communication module is used to communicate with the wireless communication apparatus so as to obtain authorization data. Each of the at least one wireless communication module is operated at a working frequency capable of penetrating through the display panel to communicate with the wireless communication apparatus. An authorization process related to a content of the frame is executed by using the received authorization data.
