8.1Power on
(1) Turn on the power supply in the order of GND- V
, GND-VLCD (VH), and VM. VM-VEE is
generated automatically. In this case, input GND to the
DISPOFF
pin.
(2) The LCD level forcibely outputs the VM level by the DISPOFF function.
(3) The DISPOFF function has a priority even if input signal distortion occurs immediately after V
CC
input.
(4) Then input the predetermined signals to initialize the driver registers. In this case, assure a
period for more than one frame.
(5) Preparation for normal display is thus completed. Cancel the DISPOFF function by setting the
DISPOFF
pin to V
. At this point, the levels of VEE (VL), VLCD (VH) and VM must have
reached the predetermined respective voltage.
8.2Shut down
As a rule, shut down in order opposite to that used for power on.
(1) Set the
DISPOFF
pin to GND.
(2) At first shut off the LCD power supply GND-VLCD (VH), at same time GND-VEE (VL) get to VM.
Next shut off the VM.
(3) Set V
CC
and the input signal to GND.
At this point, VEE (VL), VLCD (VH) and VM pin input must completely drop to 0 V.
Since the DISPOFF function is inactivated when the V
level drops to GND, the LCD output may
output a level other than VM. Therefore, an incorrect display may appear at shut down or power
on.
