Duty
270 Hz (typ., frequency of luminance control)
In the maximum luminance, the inverter current is DC. However, in the luminance control by BRTP signal, the
above duty varies 100% to 20% and the spike current, which causes the noise on the screen, may be observed. In
this case, adjust the value of the capacitance in the above filter to eliminate the noise on the screen.
