Display Panel Power Control for Office Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Office machines with display panels consume excessive power, even when operating normally, due to unnecessary power usage by the display panel.
Innovation Solution
Implementing a power-saving method that sets the office machine into standby mode, detects errors, and controls the display panel to turn on only when errors are detected, while keeping it off otherwise, and allowing user-controlled on/off functionality to minimize power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display panel is kept on to display information, then user awareness of machine status is improved, but power consumption increases
Solution Approach 1:
The display panel operates periodically rather than continuously. It remains off during normal operation and only activates when errors are detected or during specific operational phases, reducing power consumption while maintaining necessary information display functionality
Solution Approach 2:
The essential function of indicating machine status is extracted from the main display panel and assigned to a separate display lamp. This allows the display panel to remain off during normal operation while the lamp provides continuous status indication, separating the information display function from the power-consuming display panel
2Reliability
If the display panel is turned on to display error information, then error detection capability is improved, but power consumption increases
Solution Approach 1:
The display panel is activated periodically only when error detection is required, rather than remaining continuously on. The controller turns on the display panel specifically when an error is detected, maintaining reliability while minimizing power consumption during normal operation
Solution Approach 2:
The controller acts as an intermediary that monitors error conditions and selectively activates the display panel only when necessary. This intermediary control mechanism ensures error information is displayed when needed while avoiding unnecessary power consumption during normal operation
3Ease of operation
If the display panel remains on during normal operation, then information display functionality is improved, but unnecessary power consumption occurs
Solution Approach 1:
The basic status indication function is extracted from the display panel and assigned to a separate display lamp. This allows the display panel to be turned off during normal operation, eliminating unnecessary power consumption while maintaining essential information display through the lamp
Solution Approach 2:
The display panel operates periodically rather than continuously, remaining off during normal operation and activating only when errors are detected or during specific operational phases, thereby eliminating unnecessary power consumption while preserving information display functionality when needed

AI summary
An apparatus and method for saving power in an office machine having a display panel are provided. The method comprises setting the apparatus in an operation standby mode, detecting whether an error exists in the apparatus and turning on the display panel to display the error thereon when the error is detected. Furthermore, the apparatus keeps the display panel in an off state when the error is not detected. Thus, the exemplary embodiments of the present invention provide a power saving method of an office machine which prevents unnecessary power consumption during an operation of an office machine having a display panel.
