Animation of how strobing reduces motion blur
Posted: 03 Jan 2014, 18:27
For new visitors who are unaware of strobing, here is a poor, flickery, low-frequency (but VERY educational) animation of software-based strobing (black frame insertion) can reduce motion blur. (View this in a stutterfree browser such as Google Chrome, Aero enabled, on primary monitor only).
LightBoost is a hardware-based strobe backlight. Hardware-based strobing can be done on a sub-frame basis (e.g. LightBoost can flash the backlight for only 1/700th of a second, once per refresh). Such strobe backlight LCD's have about 90% less motion blur than regular LCD, allowing CRT clarity motion on LCD's. The LCD pixel transitions occur in total darkness, and the screen is flashed only on fully refreshed frames. So your eyes never see most of LCD pixel transition limitations, and motion clarity becomes limited only by how briefly the backlight can be flashed. Strobing reduces persistence: The length of time pixels are visible to the human eye. Excellent articles can be seen in LightBoost media coverage.
In addition to the well-known LightBoost, modern hardware-based strobe backlights include:
- EIZO Turbo240 in Foris FG2421
- BENQ Blur Reduction in Z-series monitors (XL2720Z, XL2411Z, and XL2420Z)
- GSYNC's optional lightboot sequel, called Ultra Low Motion Blur (ULMB)
- Sony Motionflow Impulse - Equivalent of LightBoost; game mode compatible & interpolation-free (no fake frames).
