2. Dip conditions for supply voltage
VMIN=11.4V, Vt=9.6V
1. Vt < VCC < VMIN
td < 20ms
2. VCC < Vt
This case is described below *1
*1 The LCD module shuts down when VCC < Vt
It should also follow the 1. on-off sequence of VCC and data
Note: 2)
1. Typical current situation: 16-gray-bar pattern
VCC=12.0V,
Gray scale: GS(16n)
N=0~15
The explanation of each gray scale, GS(4n), is described on page 12.
