Mirror Display Power Management for Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mirror displays with external power sources face limitations in mobility due to size constraints and power consumption, making it difficult to operate large displays solely with a battery.
Innovation Solution
A method and electronic device that selectively use either external power or battery power based on availability, allowing the mirror display to efficiently manage power and maintain functionality, especially in scenarios where external power is not available.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large display (at least 14 inches) is used in the mirror display, then the display area and visual quality are improved, but the power consumption increases significantly, making it difficult to operate solely with a battery
Solution Approach 1:
The system dynamically switches between external power mode and battery power mode based on the connection status of external power. When external power is available, the large display operates at full capacity. When external power is disconnected, the system transitions to battery power mode, managing the display operation within battery power constraints, thus adapting the power consumption to available power sources.
2Power
If only external power is used to operate the mirror display, then sufficient power is available for large display operation, but the mobility and portability of the device deteriorates
Solution Approach 1:
The mirror display is designed with dual power source capability, supporting both external power input and internal battery power. This multi-functionality allows the device to operate in different modes: connected to external power for stationary use with full display capabilities, or using battery power for mobile applications, thus serving multiple usage scenarios with a single device design.
3Ease of operation
If a battery is embedded in the mirror display to improve mobility, then portability is enhanced, but the device complexity and power management requirements increase
Solution Approach 1:
The power supply unit includes a power detection mechanism that automatically detects whether external power is connected and provides feedback to the control unit. Based on this feedback, the system automatically switches between external power mode and battery power mode, eliminating the need for manual user intervention and simplifying the user interface despite the underlying power management complexity.
4Adaptability or versatility
If the mirror display is designed to support both external power and battery power, then versatility and mobility are improved, but the device complexity increases due to additional power management components
Solution Approach 1:
The power supply unit acts as an intermediary between external power sources and the display system. It includes power detection circuits and switching mechanisms that automatically manage the transition between external power and battery power, shielding the user from the complexity of dual power source management while maintaining versatility.

AI summary
A method of controlling a mirror display and an electronic device are provided. The method includes identifying whether external power is input to the electronic device; and providing operation power to the mirror display by selectively providing one of the external power and battery power to the mirror display as the operating power according to whether the external power is input to the mirror display.
