Multiplexing more than 100 7segment LED displays with a microcontroller
What are the multiplexing techniques to interface about 100 7segment displays to a 8-bit microcontroller (say 8051).
If I hook up a row of decoders to the control pins of the display array on a common bus, I guess I might acheive it. But I doubt if there would be any flicker while doing so.
Say for example, If I have 64 pairs of 7seg digits to be controlled, I may do a round-robin multiplex to the tune that each pair is ON for about 1ms in every 64 ms.
Will that be possible, given that the duty cycle and frequency are of that order?
Thanks for your invaluable response.
