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
