A large reason why CRTs are rather excellent in regards to motion is because they're not sample and hold displays resulting in very low duty cycles (dominated by the phosphor's fall time of somewhere between 200-1000 µs, as rise time is basically instant at <20 ns or so and video bandwidth is well above 100 MHz). That's the main reason why a 240 Hz LCD using BFI for strobing (D=0.5) can't compete with a 120 Hz CRT (D~0.05 or so). |
