2）Dip conditions for supply voltage
*1 The LCD module shuts down when VCC12V<Vth. It should also follow the 1) on-off sequence
【Note2】
【Note3】When power is supplied or when LCD starts to work by incoming input signal, the rush current flows.
【Note4】It doesn’t contain input ripple voltage of inverter switching by duty control.
（Vmin,Vth）=（11.4V,9.6V）
of VCC12V and data.
1）Typical current situation : 16-gray-bar pattern
2）Maximum current situation : The left pattern of a figure (pattern1) by using the right scale of a figure (scale1).
Note: S = 255
Vcc=+12.0V
Gray scale : GS(16N)
The explanation of each gray scale ,GS(16n), is described below section 8.
i) Vth≦VCC12V＜Vmin
ii) VCC12V＜Vth
VS means the voltage of V255 scale.
The ripple voltage of inverter by duty control: 300mVp-p
This case is described below *1.
td≦20ms
Be careful that power circuit is never less than 11V when the rush current flows.
