Screen Saver Method for Image Apparatus Display Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image apparatuses suffer from overheating and potential screen damage due to prolonged music playback with unchanging screens, leading to afterimages and fluorescent material degradation.
Innovation Solution
A screen saving method that involves displaying audio playback data and varying the image position over time using a control unit, timer, and display unit, activating a screen saver mode after a preset time to prevent damage and provide user information during extended music playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a still screen is displayed during prolonged music playback, then audio playback information can be shown to users, but the screen overheats and suffers damage
Solution Approach 1:
The patent applies dynamics by transitioning the static screen display into a dynamic moving image display. The screen saver mode changes the still screen into a moving image that varies over time, preventing heat accumulation while maintaining audio playback information visibility. This resolves the contradiction by making the display dynamic rather than static.
Solution Approach 2:
The patent implements periodic action through the screen saver mode that activates after a preset time interval during music playback. The system periodically changes the display from a still screen to a moving image, then returns to the still screen after another interval. This periodic transformation prevents continuous overheating while ensuring information remains accessible to users.
2Object-affected harmful factors
If the screen is turned off during music playback, then overheating is prevented, but users cannot access song information
Solution Approach 1:
The patent applies preliminary action by pre-configuring the screen saver mode to activate automatically after a preset time interval during music playback. Instead of waiting for user initiation or turning off the screen completely, the system proactively implements a protective display mode that prevents overheating while maintaining information visibility. This resolves the contradiction by taking preventive action before damage occurs.
Solution Approach 2:
The patent introduces screen saver mode as an intermediary between the music playback function and the display function. This intermediary mode transforms the display output from a still screen (which causes overheating) to a moving image (which prevents overheating), while still conveying audio playback information. The screen saver mode acts as a mediator that satisfies both overheating prevention and information display requirements.
3Device complexity
If a still screen is displayed during extended music playback, then minimal processing is required, but fluorescent material degrades and afterimages occur
Solution Approach 1:
The patent applies dynamics by changing the display from a static still screen to a dynamic moving image during music playback. This dynamic transformation prevents fluorescent material degradation and afterimage formation while maintaining relatively simple processing requirements. The moving image varies in position and characteristics over time, preventing the harmful effects of static display without significantly increasing processing complexity.
Solution Approach 2:
The patent implements parameter changes by modifying display parameters such as image position, brightness, and pattern over time during music playback. These parameter changes transform the still screen into a moving image, preventing fluorescent material damage and afterimages. The system adjusts display parameters periodically to maintain protection while keeping processing requirements manageable.
Data Source
AI summary
A screen saving method of an image apparatus is provided. The screen saving method includes playing back an audio signal, and displaying a screen saving image that includes audio playback data, according to the played back audio signal. The image apparatus includes a media playback unit, a display unit, and a control unit. The media playback unit plays back the audio signal. The display unit displays the audio playback data. The control unit controls the displaying of the screen saving image, and varies the position of the screen saving image over time.
