Display Controller Standby Mode Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices in standby mode cannot display information such as time, requiring reactivation to access this information, which leads to high power consumption and hardware loss.
Innovation Solution
A display controller that includes a mode trigger, mode controller, and signal switcher, allowing the display to switch between normal and standby modes with reduced power consumption by triggering the standby display mode directly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the display device is kept in standby mode to save power, then power consumption is reduced, but the display cannot show information such as time or date
Solution Approach 1:
The display screen is divided into a first display area and a second display area. The first display area remains in standby mode to save power, while the second display area is activated to display time information. This segmentation allows the system to display necessary information without fully activating the entire display, thus reducing power consumption while maintaining information availability.
2Loss of information
If the display device is fully activated to display information, then all information including time can be displayed, but power consumption increases
Solution Approach 1:
Different regions of the display screen are assigned different functional qualities. The first display area maintains standby characteristics (low power consumption), while the second display area is activated with full display capabilities. This local differentiation allows the system to provide information display functionality where needed while keeping other areas in energy-saving mode.
3Loss of information
If the display device is frequently awakened to check time information, then time can be accessed, but hardware loss increases
Solution Approach 1:
The time information is pre-loaded and displayed in the second display area while the display device remains in standby mode. This preliminary arrangement of information allows users to access time information without needing to fully activate or awaken the display device, thereby reducing the frequency of wake-up cycles and minimizing hardware wear and loss.
