Display Clock Adaptation for Low-Frame-Rate Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses face inefficiencies in power consumption due to the use of fixed clock frequencies, leading to energy waste when handling low-frame rate content, as they are not adaptable to varying frame rates.
Innovation Solution
The display apparatus adjusts its clock parameters, such as frequency and voltage strength, based on detected frame rates to generate an adjusted clock signal, optimizing power consumption by matching the signal transmission speed to the input image frame rate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a fixed clock frequency tailored to high frame rate is used, then high frame rate content can be processed, but power consumption increases unnecessarily when handling low frame rate content
Solution Approach 1:
The clock frequency is made dynamic rather than fixed, allowing it to adjust according to the actual frame rate of input content. The system detects the frame rate and varies the clock frequency accordingly, enabling high frequencies for high frame rate content and low frequencies for low frame rate content, thus resolving the contradiction between processing capability and power consumption.
Solution Approach 2:
The clock frequency parameter is changed based on the detected frame rate of input content. By varying this critical parameter dynamically, the system optimizes power consumption while maintaining the ability to process different frame rates, directly addressing the technical contradiction.
2Reliability
If a fixed clock frequency is used, then signal transmission stability is maintained, but energy waste occurs when handling low frame rate content
Solution Approach 1:
The system dynamically adjusts clock frequency based on actual content requirements rather than maintaining a fixed high frequency. This dynamic adaptation reduces energy waste during low frame rate playback while the clock data recovery circuit ensures signal transmission stability is maintained through proper synchronization.
Solution Approach 2:
The system incorporates frame rate detection as a feedback mechanism that informs clock frequency adjustment. By continuously monitoring the frame rate and adjusting the clock frequency accordingly, the system optimizes energy consumption while maintaining reliable signal transmission through the V-by-One interface.
