Wearable Display Sub-Display for Connected Device Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices lack the ability to display identification information of connected devices, leading to security and usability issues such as hacking and user confusion.
Innovation Solution
A wearable device with a display panel and a memory that stores identification information of connected devices, allowing the sub-display area to show this information, and a detecting controller to determine types of external contact for controlling signal transmission to connected devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If wearable devices are designed to be small and lightweight, then portability and wearability are improved, but the ability to display detailed information such as identification information of connected devices deteriorates
Solution Approach 1:
The display is divided into a main display area and a sub-display area. The main display area shows primary information while the sub-display area specifically displays identification information of connected devices. This segmentation allows the wearable device to display comprehensive information without requiring a larger overall display size, thus maintaining portability while preventing information loss.
2Reliability
If the wearable device stores and displays identification information of connected devices, then security and usability are improved, but device complexity increases
Solution Approach 1:
The memory for storing identification information is integrated into the driver IC of the display device. By merging the storage function with the display driver, the patent eliminates the need for separate memory components and reduces overall device complexity while still enabling security and usability improvements through identification information display.
Solution Approach 2:
The driver IC is designed to perform multiple functions: driving the display panel and simultaneously storing identification information of connected devices. This multi-functionality reduces the number of separate components needed, thereby reducing device complexity while maintaining security and usability benefits.
3Use of energy by moving object
If the sub-display area displays identification information without processor control, then power consumption is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The driver IC autonomously manages the display of identification information in the sub-display area without requiring continuous processor control. The driver IC reads from its integrated memory and controls the display independently, enabling the system to operate with lower power consumption while the self-service nature of the driver IC handles the complexity of coordination internally.
