Display Device WOL Function Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses that support Wake On LAN (WOL) functions consume unnecessary standby power when the feature is not in use, as they must maintain power to the communicator at all times to receive wake-up signals, leading to increased energy consumption.
Innovation Solution
A display apparatus with a controller that determines whether to enable or disable the WOL function based on network settings, switching between standby and operation power modes accordingly, and providing a user menu to configure WOL settings, allowing users to turn the feature on, off, or set it to auto-mode based on network usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the WOL function is supported by applying standby power to the communicator all the time, then the display apparatus can receive wake-up signals remotely, but the standby power consumption increases unnecessarily
Solution Approach 1:
The patent applies dynamics by making the power supply state of the communicator adjustable between static states (standby power always on, or always off). The controller dynamically switches the communicator's power state based on whether the WOL function is enabled, allowing the system to adapt its power consumption characteristics to actual usage requirements rather than maintaining a fixed power state
2Adaptability or versatility
If the WOL function is enabled to allow remote booting, then user convenience is enhanced, but the communicator consumes power continuously even when not needed
Solution Approach 1:
The patent applies parameter changes by modifying the power supply parameter (standby power) conditionally based on the WOL function's enabled state. When WOL is disabled, the standby power parameter is set to zero, eliminating unnecessary energy loss while preserving the capability to enable it when needed for remote management

AI summary
A display apparatus and a method for controlling the display apparatus thereof are provided. The display apparatus includes a communicator configured to receive a power-on command from an external apparatus to perform a Wake On LAN (WOL) function and a controller configured to determine whether the WOL function is turned either on or off according to a network setting state.
