You can do that? That is beautiful.


Yep, I've done this before with a LED matrix -- shut off OE, update the shift registers and switch to the next row, then turn OE back on. This gets rid of any ghosting between the rows.

You can get flickering with this approach, if a lot of data is transmitted.

A better approach is to use the latch.
