OLED is 1 order of magnitude slower in response for high->low transitions. CRTs 0->high transitions are sometimes 150000 times faster than OLED. The 0->high transition is slow on some OLEDs at particular refresh rates (this 480Hz OLED tested in one of the fastest and takes 3ms), resulting in 'black smear' when moving white subjects on black backgrounds. Interestingly, at 60Hz, the same transition is 0.4ms, with no black smear. Active Matrix OLEDs on phones have very slow 15ms black to white transitions, resulting in strong black smear. Monitors use a passive matrix to control the OLED electrodes. 60Hz fed to this OLED has only 0.1 ms slower pixel response times than at 480Hz, this LG is one of the best. OLED is the fastest display tech that is currently in production, though it still is significantly slower than a CRT.
