Wearable Display Clock Data Encoding for Sleep Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices currently only display the current time when in wake-up mode and do not provide watch functionality in sleep mode due to their display being powered off.
Innovation Solution
An electronic device method and system that generates and displays screen data, such as clock screens, using separate clocks for operation modes, allowing content display regardless of the device's operation mode by encoding and decoding screen data for continuous display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the display is powered off in sleep mode to save energy, then energy consumption is reduced, but the device cannot display time or provide watch functionality
Solution Approach 1:
The patent divides the display system into two independent parts: a first display processor handling wake-up mode operations and a second display processor handling sleep mode operations. This segmentation allows each processor to operate independently with its own clock, enabling the second processor to maintain display functionality during sleep mode while the first processor enters low-power state, thus resolving the contradiction between energy saving and functionality availability.
2Device complexity
If a single clock is used for the display processor, then device complexity is reduced, but the device cannot display content in both wake-up and sleep modes simultaneously
Solution Approach 1:
The patent implements multi-functionality by providing two separate display processors that can each handle display operations independently. The first display processor serves wake-up mode while the second serves sleep mode, allowing the system to adapt to different operational states without requiring complex clock switching or mode-dependent configuration changes, thus achieving versatility without proportionally increasing complexity.
Data Source
AI summary
A method for displaying content by an electronic device is provided. The method includes generating converted data by encoding a plurality of screen data according to first clocks, restoring the screen data by decoding the converted data based on second clocks separate from the first clocks, and displaying the restored screen data.
