7.1 Turning on the power
1)Turn on the power in the order of GND-V
CC
, GND-VEE (VL), GND-VLCD (VH), and
VM. Then, ground the
',63
pin.
2) The LCD forcibly outputs the VM level by the DISPOFF function.
3) Even if an input signal is disturbed immediately after V
CC
is applied, the DISPOFF function
has priority.
4) Input the appropriate signal to initialize the registers in the driver. The initialization period
must be at least one frame.
5) The preparation for normal display is completed. Apply the V
CC
level to the
',63
pin to
cancel the DISPOFF function. At this time, the level of pins VEE (VL), VLCD (VH), and
VM must rise to the appropriate potential.
7.2 Turning off the power
The procedure is basically the reverse of that for turning on the power.
1) Ground the
',63
pin.
2) Turn off the LCD power in the order of VM, GND-VLCD (VH), and GND-VEE (VL).
3) Ground V
CC
and the input signal.
At this time, the level of pins VEE (VL), VLCD (VH), and VM must fall to 0 V. Since the
DISPOFF function stops when V
CC
falls to 0 V, the LCD may output a level other than VM.
Therefore, a display failure may occur when the power is turned off or on.
