The INH Pin and Display Control
Since the IC internal data (the display data and the control data) is undefined when power is first applied, applications
should set the INH pin low at the same time as power is applied to turn off the display (This sets the S1 to S73,
S74/COM10, S75/COM9, and COM1 to COM8 to the V
LCD
4 level and the P1 to P4 to the V
SS
level.) and during this
period send serial data from the controller. The controller should then set the INH pin high after the data transfer has
completed. This procedure prevents meaningless displays at power on. (See figures 3, 4, and 5.)
Power Supply Sequence
The following sequences must be observed when power is turned on and off. (See figures 3, 4, and 5.)
Power on :Logic block power supply(V
DD
) on
→
LCD driver block power supply(V
LCD
) on
Power off:LCD driver block power supply(V
LCD
) off
→
Logic block power supply(V
DD
) off
However, if the logic and LCD driver blocks use a shared power supply, then the power supplies can be turned on and off
at the same time.
