My recollection is that LCD panels have sufficient bandwidth to display one line of information at a time with standard television formats, thus meaning that they can at least switch in the 15 kHz range. Therefore they should be fine for NBTV applications. What I do not know is the linearity of response of such panels to analogue input signals. The common way to modulate them is by way of pulse duration modulation. Such an LCD modulator might need an analogue to digital converter to drive the LCD panel.Klaas Robers wrote:I wonder if the speed of LCD as a light modulator would be fast enough to modulate the light up to a frequency of 10 kHz....
