Moving Picture Response Time (MPRT) measures the time a pixel remains visible on the screen as an image moves.
It is a crucial metric for evaluating the motion clarity of a display.
MPRT differs from traditional response time measurements like Gray-to-Gray (GtG) by focusing on the duration of visible persistence.
MPRT is particularly important in gaming and fast-motion content where visual clarity is critical.
1ms MPRT reduces motion blur, making fast-moving objects appear sharper.
This improvement is essential for gamers who need precise and clear visuals to enhance their gameplay experience.
Motion blur is a visual phenomenon where moving objects appear blurred or smeared on the screen.
In digital displays such as LCDs and OLEDs, motion blur primarily occurs due to the ‘sample-and-hold’ effect.
In this process, a video frame is held steady on the screen until the next frame is ready to be displayed.
This method, while effective for maintaining image stability, can sometimes conflict with our eyes’ natural motion processing mechanism, leading to the perception of blur.
Each frame persists on the screen for a certain duration, and during high-speed motion, our eyes can perceive these individual frames, resulting in a blur effect.
In other words, your eyes are in a different position at the beginning of a refresh than at the end of a refresh. This results in the frame being blurred across your retina.
A higher refresh rate of the display reduces the persistence of each frame, leading to smoother transitions between frames and consequently, less motion blur.
