Outline of Differences between G5 and G6 Drive Circuits
11
1. Y Drive Reset Pulse
G5: 3 times reset pulses --> G6: 1time reset pulse
Purpose: Due to improve the black level.
Because Plus Reset voltage on Y Drive Assy is larger than the VSUS voltage,
a power regulator for the Plus Reset was added and Mask Circuit was changed to two ways.
Minus reset circuit was also added on Y Drive Assy
2. X & Y Drive Resonance circuit
G5: Discrete & double resonance circuit --> G6: Module IC, single resonance circuit
Purpose: Due to cost down
3. X Drive MASK Module IC
G5: Using 2 ICs --> G6 : Using 1 IC
Purpose: Due to cost down
Because Sustain pulse was slightly changed, SUS-Clamp boards were added.
4. Change of SCAN IC
Purpose: To reduce cost.

Since the value of Plus Reset Voltage became beyond the
value of VSUS, Plus Reset connect to PSUS and SUSMSK
