Mar 2, 2, datashheet, Why do you need to multiplex the display any faster than the minimum rate needed to avoid visual display flicker? Roderick Young likes this. Sep 4, 6. Aug 1, 7, 2, If by display you mean a visual indicator to be seen by Earth-type humans, then updating it more often than 20 times per second is meaningless.


Yes, cd028 people can perceive flicker at 20 Hz, but that’s not the same as understanding correctly what is being displayed.

Sep 4, 9. Mar 14, 20, 5, Sep 4, Also note that, depending on how the multiplexing is done, every time the display is updated it datasheet a little brightness compared to being on continuously. So it is possible that the more frequently the display is updated, the less bright it appears. Here is an extreme example.

For lamps, each one is blinked every 1 millisecond for 1 microsecond. If the refresh rate is decreased to KHz, now each lamp is blinked for 10 us, a No, the processor can be off doing other things or just plain sitting there waiting for the next Hz tick, and power is sitting on the last lamp until it is told to move.

Note zero latency between moves.
