The BRIGHTNESS and CONTRAST are DC controlled. The brightness loop includes a comparator gated by an internally generated pulse. Thanks to the contrast pre-adjust pin, this device is well suited for color application too. The output stage structure (A class current output), allows to use a very cheap high voltage amplifier using only one transistor.
