I cannot understand why they have indicated 1/10 while the part has only 8 columns and so it should be 1/8 logically. Why? I dunno.


I've had a look at few LED datasheets and they also specify a duty-cycle of 1/10. So I guess it's a "LED-industry standard" to specify max current and pulse-width at 1/10th duty cycle. It apparently is not related to 8 columns... (datasheet I read was for single LED.)
