While some of this is true, This needs further explanation.
Display Science
For those who haven't been studying the redesigned
Area 51 Display Research Section of Blur Busters lately, I need to correct some myths.
OLEDs
also have motion blur too unless impulse driven too. Even 0ms GtG has lots of motion blur because MPRT is still big.
VR headsets such as Oculus Rift can strobe (impulse-drive like a CRT), as well as LC CX OLED BFI setting. However, the MPRT of Oculus Rift Original is 2ms MPRT, and LG CX OLED is about 4ms MPRT. Be careful not to confuse GtG and MPRT -- see
Pixel Response FAQ: Two Pixel Response Benchmarks: GtG Versus MPRT. To kill motion blur, both GtG *and* MPRT must be low. OLED has fast GtG but high MPRT, unless strobed.
Faster GtG Can Reduce Blur -- But Only To a Point
However, faster GtG does lower the flicker fusion threshold of the stutter-to-blur continuum where objects during low framerates "appear" to vibrate (like slow guitar/harp string) and high framerates vibrate so fast they blur (like a fast guitar/harp string). Regular stutter (aka 30fps) and persistence motion blur (aka 120fps) is the same thing --- the stutter-to-blur continuum is easily watched at
www.testufo.com/vrr (a frame rate ramping animation during variable refresh rate).
Slow GtG fuzzies up the fade between refresh cycles as seen in
High Speed Videos of LCD Refresh Cycles (videos of LCD and OLED in high speed video), which can lower the threshold of the stutter-to-blur continuum.
Some great animations to watch to help you understand the stutter-to-blur continuum:
Stutters & Persistence Motion Blur is the Same Thing
It's simply a function of how slow/fast the regular-stutter vibration. Super fast stutter vibrates so fast it blends into motion blur.
View all of the above on any fast-GtG display (LCD or OLED, such as TN LCD, modern "1ms-GtG"-IPS-LCD, or an OLED). You'll observe once GtG is an insignificant percentage of refresh cycle, these things are easy to observe (assuming framerate = Hz).
1. Motion blur is pixel visibility time
2. Pixel visibility time of a strobed display is the flash time
3. Pixel visibility time of a non-strobed display is the refresh cycle time
4. Stutter and persistence blur is the same thing; it's a function of the flicker fusion threshold where stutter blends to blur
5. OLED has motion blur just like LCDs
6. You need to flash briefer to reduce motion blur on an impulse driven display.
Once you've seen all the educational animations, this helps greatly improve the understanding of displays.
Now, LCDs do not need to be 1000Hz to reduce motion blur -- you can simply use strobing. But strobing (CRT, LCD, OLED) are just a humankind bandaid because real-life doesn't flicker or strobe. We need 1000Hz OLEDs / LCDs, regardless of whether OLED or LCD.
There are only two ways to shorten frame visibility time (aka motion blur)
1. Flash the frame briefer (1ms MPRT requires flashing each frame only for 1ms)
2. Add more frames in more refresh cycles per second. (1ms MPRT requires 1000fps @ 1000Hz)
And, the OP forgot to post both images, which are
equally important due to context
