Hi, all.

I have a question on TLC5958.

According to the application report(SLVA645) P21, each segment has 256 GCLK.
However,it seems each segment has 257 GCLK, according to p22 Figure15.
I'd like to calculate frefresh(=1/tsub-period).
Which value should I use to calculate it?

Best regards.

Hi Tokumoto-san,

Each segment should have 257 GCLK. The last GCLK is used for channel turn off.

You can use 257GCLK for the calculation.

Best regards,

Feifei
