Persistence (MPRT) is pixel visibility time. Your eye movements can “smear” the frame across your vision, creating motion blur.Even though GtG can be fast, the MPRT can still be slow. Measuring electronically is more reliable with cutoff points, especially back in the old days. 1ms), the MPRT has not gotten faster because As you track your eyes on moving objects on a screen, your eyes are in a different positions at the beginning versus end of a refresh cycle.On most 60Hz displays, a frame is continuously displayed for no less than 1/60sec. Try this animation on a TN or OLED display which often has <1ms GtG but 16.7ms MPRT!To help assist future 1000 Hz developments, GPUs can incorporate Pre-requisite technologies are starting to be demonstrated successfully in the laboratory, and The 90% measurement cutoff threshold is arbitrary, only intended to make scientific measurement easier.
Even for 60Hz OLED displays, the MPRTIn a high speed video, slow GtG pixel response looks like a refresh cycle “LCD subpixels are actually monochrome, and colors on screens are accomplished via color filters.The pixel response time for each individual color channel is usually identical.Pixel response can be a tiny fraction of a refresh cycle, and still produce human-visible artifacts such as ghosting or coronas — especially if pixel transitions are different speeds for different colors.One millisecond translates to 1 pixel per 1000 pixels/second motion. Response time is a measure of how fast a pixel can change from one color to another, that is, from one shade of gray to another. See There is a valid reason why manufacturer GtG specifications are often more aggressive than real-world GtG numbers. Ignoring transmission time for a moment, the response time is the sum of the service time and wait time. MPRT is a more accurate representation of visible motion blur blur (see Eye Tracking Motion Blur Animation demo). Even though GtG pixel response time has become faster (e.g. AOC Brings in Two More AGON High Performance Monitors ASUS ROG 3 Phone Conquers Mobile Gaming Market, With Hidden 160 Hz Overclock New “Blur Busters Approved” Monitor Certification Program Announced at CES 2020 for Display Motion Blur Reduction Modes Blur Busters Law: The Amazing Journey To Future 1000Hz Displays Frame Rate Amplification Tech (FRAT) — More Frame Rate With Better Graphics VR Guide 2019: Compare Popular Virtual Reality Headsets Why Is GtG Called Grey-To-Grey Instead Of Color-To-Color?120Hz ideal sample-and-hold display has identical motion blur (MPRTfor the same physical panning velocity of full frame rate material.for simplicity and to match human-perceived motion blur on fast sample-and-hold displays. I was just unsure if you were saying that response time doesn't matter in general or if you were saying that 2 - 5 ms doesn't matter. Normal response time right now is ~1ms for TN panels and ~4ms for IPS and VA panels. That service can be anything from a memory fetch, to a disk IO, to a complex database query, or loading a full web page. The response time refers to how long this change takes. GTG (grey to grey) has become the popular metric for measuring response times because it produces lower numbers than BTB (black to black) which used to be the standard. Reason include noise margins in measuring equipment (especially near blacks) and extremely slow pixel response in old displays that sometimes never perfectly reached 100% even after many refresh cycles.Manufacturers use the VESA GtG measurement method, measuring the GtG pixel response speed from the 10% point to the 90% point:This can miss the first 10% and final 10% of the GtG pixel response curve, which may sometimes still be human-visible. Thanks to strobe backlight technologies, the best strobed LCDs can have lower MPRT(90%) than a slower-phosphor CRT. GtG and MPRT are two different pixel response benchmarks for displays, screens, televisions, and monitors.Even when a pixel finishes its GtG transition from one color to another color, a fully refreshed pixel can stay continuously visible or static until the next refresh cycle. Different shades can have different GtG pixel transition speeds from one source color to one destination color. TFT Central or others).
