So I have a display which has an integrated LED driver for backlight. The driver expects PWM input with frequency between 10 kHz and 100 kHz. The only other information I have are the maximum voltage and current and that there are two LED strings.
Most of the research results I found concern themselves with PWM frequencies in the very low frequency range and there seems to be little information for PWM frequencies above 3 kHz. It seems that the flicker is not an issue above 3 kHz.
So are there any other important factors, other than EMI concerns, which need to be taken into account when selecting the PWM frequency?
