【Note1】
1）On-off sequences of Vcc and data
0＜t1≦60ms
0＜t2≦10ms
0≦t3≦1s
t4≧100ms
2）Dip conditions for supply voltage
Vmin,Vth=11.4V, 9.6V
1) Vth ≦Vcc＜ Vmin
td≦ 20ms
2) Vcc＜Vth
The LCD module shuts down.
【Note2】 Typical current situation : 256-gray-bar pattern
Vcc=+12.0V
The explanation of each gray scale ,GS,
is described below section 8.
