Display Apparatus Dual Communication Protocol for Reliable Ambient Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses struggle to maintain effective communication with mobile devices for ambient mode operations when users are not nearby, leading to inefficient standby mode management due to unreliable short-range wireless communication.
Innovation Solution
The display apparatus employs a dual communication protocol approach using Bluetooth Low Energy (BLE) and Wi-Fi, switching between them to maintain communication and ensure the ambient mode is only active when both protocols are available, and reverts to standby mode when either protocol is disconnected, utilizing MAC address retrieval through ARP requests and mobile app assistance.

Engineering Contradiction Analysis
1Ease of operation
If short-range wireless communication (BLE) is used to detect user proximity for ambient mode operation, then the display apparatus can provide convenient ambient mode when user is nearby, but communication reliability deteriorates when user is not nearby causing unnecessary mode switching
Solution Approach 1:
The patent introduces Wi-Fi communication as an intermediary mechanism to verify user proximity. Instead of relying solely on BLE which has limited range and reliability, the system uses Wi-Fi as a mediator to confirm the mobile device's presence. The display apparatus checks for Wi-Fi connection status as an additional verification layer, ensuring that ambient mode is only activated when both BLE and Wi-Fi confirm user presence, thereby resolving the reliability issue while maintaining ease of operation.
2Reliability
If dual communication protocol (BLE and Wi-Fi) verification is implemented to ensure reliable user presence detection, then communication reliability improves, but device complexity increases
Solution Approach 1:
The patent leverages the universality of Wi-Fi technology which already exists in most modern mobile devices for internet connectivity. By utilizing this existing universal communication capability for proximity detection purposes, the system avoids adding specialized hardware or complex proprietary protocols. The Wi-Fi module serves multiple functions: internet connectivity, proximity detection, and mode verification, thereby improving reliability without proportionally increasing device complexity.
Solution Approach 2:
The system uses the mobile device's own Wi-Fi connectivity status (which the user already maintains for normal operation) to self-verify presence. The display apparatus queries the mobile device's Wi-Fi connection state, and the mobile device provides this information from its own network stack. This self-service approach eliminates the need for additional sensors or complex interaction protocols, as the mobile device's existing network infrastructure serves the dual purpose of both communication and proximity verification.
3Ease of operation
If ambient mode is maintained based on unreliable BLE communication, then ease of operation is preserved, but energy consumption increases due to unnecessary screen activation
Solution Approach 1:
The patent implements a feedback mechanism where the display apparatus continuously monitors both BLE and Wi-Fi connection statuses to dynamically adjust ambient mode activation. The system receives feedback from the mobile device regarding Wi-Fi connection state and uses this feedback to verify user presence before maintaining ambient mode. This multi-layer feedback system ensures that ambient mode is only sustained when both communication protocols confirm active user presence, preventing unnecessary screen activation and reducing power consumption while preserving user convenience.
