I'm reading through this article on LED RGB Matrix panels.
I don't understand its explanation about what the scan rate ratio means:
The scan rate, then, describes how many pixels we're scanning at a time. In a 1:16 scan rate panel, we're lighting 1/16 of the pixels at any given time. on a 32-pixel wide display, this is pretty convenient as each of those 16 groups of pixels becomes 32 pixels long, exactly one row.
Is it a ratio of the number of rows simultaneously lit to the number of LED pixels in each column? i.e., for a HxW LED matrix with scan rate of 1:R, the number of pixels simultaneously lit is H/R?
So 1:8 scan rate on a 32x64 matrix implies that a pixel from each of four rows are lit simultaneously while a 1:16 scan rate on a 32x64 matrix implies a pixel from only two rows are lit at the same time.
