Display Panel Frame Rate Synchronization to Reduce Input Lag
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses experience input lag and seamless video issues due to mismatches between the frame rate of the video and the frame rate of the display panel.
Innovation Solution
The display apparatus dynamically adjusts the frame rate of the display panel to match the frame rate of the video, allowing for seamless video output by minimizing input lag through the use of a processor that identifies the video's frame rate and adjusts the display panel's settings accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the frame rate of the display panel is increased to improve video quality, then video quality is improved, but input lag increases when the panel frame rate does not match the video frame rate
Solution Approach 1:
The display panel dynamically adjusts its frame rate based on the detected video frame rate. The system changes the panel's operating frame rate in real-time to match the video content being displayed, rather than operating at a fixed high frame rate. This dynamic adaptation eliminates input lag while preserving video quality.
Solution Approach 2:
The system changes the frame rate parameter of the display panel to match the video frame rate. By detecting the video's frame rate and adjusting the panel's frame rate parameter accordingly, the system resolves the mismatch that causes input lag while maintaining optimal video quality.
2Manufacturing precision
If the frame rate of the display panel is fixed at a high value, then video quality is improved, but the video appears lagged or not seamless when frame rates do not match
Solution Approach 1:
The display system transitions from a static fixed frame rate to a dynamic adaptive frame rate that automatically adjusts to match the video content. This dynamic behavior ensures seamless video playback by synchronizing the panel's frame rate with the video frame rate regardless of the video source.
Solution Approach 2:
The system detects the video frame rate and uses this information to adjust the display panel's frame rate. This feedback mechanism ensures that the panel operates at the optimal frame rate for the current video content, eliminating lag and ensuring seamless playback.
3Loss of time
If frame rate matching is implemented to reduce input lag, then input lag is reduced, but additional processing and control mechanisms are required
Solution Approach 1:
The display system automatically detects the video frame rate and adjusts its own operating parameters without external intervention. The system self-regulates by monitoring the incoming video signal and autonomously changing its frame rate to match, reducing input lag without requiring complex external control mechanisms.

AI summary
A display apparatus is provided. The display apparatus includes: a communication interface including a circuit; a display panel configured to be selectively driven at any one of a plurality of frame rates; and a processor configured to: identify an input frame rate of a video, based on the video being received through the communication interface, adjust a setting value of the display panel so that the display panel operates at a frame rate among the plurality of frame rates that corresponds to the input frame rate, and control the display panel to output the received video, by driving the display panel at the frame rate corresponding to the input frame rate.
