Adaptive Screensaver Controller for Digital Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital devices face challenges in effectively managing screensavers, particularly when multitasking, as existing methods do not adapt to the status of services or applications, leading to user inconvenience and potential panel burn-in.
Innovation Solution
A method for adaptively controlling screensavers based on the status of digital devices, including power consumption reduction and user intention, by using a controller to manage display windows, generate status data, and execute screensaver modes based on voter registration and response from applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screensaver is used to prevent panel burn-in, then panel reliability is improved, but user convenience deteriorates when the device supports multitasking of high-end services
Solution Approach 1:
The screensaver operation mode is made dynamic and adjustable based on device status. The controller adapts the screensaver behavior according to whether the device is in multitasking mode or single-tasking mode, allowing the screensaver to be activated or deactivated dynamically rather than following a fixed rule
Solution Approach 2:
The system changes the operational parameters of the screensaver based on device status. When multitasking is detected, the screensaver parameter is changed from active to inactive state, preventing interference with high-end services while still providing burn-in protection during normal operation
2Loss of energy
If screensaver operates without considering service/application status, then power consumption is reduced, but device functionality deteriorates due to interference with multitasking
Solution Approach 1:
The controller receives feedback signals from the service interface indicating whether high-end services or applications are being executed. Based on this feedback, the controller automatically adjusts the screensaver operation status, ensuring that the screensaver does not interfere with multitasking while still operating during normal single-tasking modes
Solution Approach 2:
The system performs preliminary detection of the device status and service execution state before activating the screensaver. By checking the service interface in advance, the system prevents screensaver activation that would interfere with multitasking, avoiding the need for user intervention to resolve conflicts
3Device complexity
If conventional screensaver method is used, then device complexity is reduced, but adaptability to different usage scenarios deteriorates
Solution Approach 1:
The controller is designed with multi-functionality, serving both as the device's central control unit and as the screensaver management system. The same controller handles both normal device operations and screensaver activation/deactivation based on service status, eliminating the need for a separate dedicated screensaver control system

AI summary
A digital device and a method of processing screensaver application in the digital device are disclosed. The digital device includes a manager to manage a display window of the digital device and to generate and to transmit a plurality of status data of the digital device to a controller, and the controller to receive a first signal from a first application requesting registration as an application voter, to transmit a second signal requesting a confirmation related to execute a second application to the first application when first status data is received from a service interface, to receive a response to the second signal from the first application, and to execute the second application to enter a screensaver mode based on the received response.
