3 . DRIVE CIRCUIT

3-1. Outline

The drive circuit is composed of 18 ICs in total as shown in

Fig. 3-1-1.

Each of them is as follows; the input amplifiers (Q408, Q508

and Q608), gamma process IC (Q701), alternation/sample

& hold ICs (Q401, Q402, Q501, Q502, Q601 and Q602),

timing generator (Q903), pulse signal buffer ICs (Q901 and

Q902), 8 bit D/A for electronic variable resistor (Q900 and

Q905) and power supply IC (Q950, Q951, Q952 and Q954).

The gamma process IC (Q701) and 8 bit D/As (Q900 and

Q905) electronic variable resistor are controlled by I

and the timing generator (Q903) is controlled by three-line
