The INH pin and Display Control
Since the LSI 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 (LC75833E, LC75833W: This
sets the S1/P1 to S8/P8, S9 to S35, and COM1 to COM3 to the VSS level. LC75833JE: This sets the S1/P1 to S8/P8, S9
to S11, S13 to S22, S25 to S34, and COM1 to COM3 to the VSS 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 Figure 3.)
Notes on the Power On/Off Sequences
Applications should observe the following sequence when turning the LC75833E, LC75833W, and LC75833JE power
on and off.
At power on: Logic block power supply (V
DD
) on
→
LCD driver block power supply (V
LCD
) on
At power off: LCD driver block power supply (V
LCD
) off
→
Logic block power supply (V
DD
) off
However, if the logic and LCD driver block use a shared power supply, then the power supplies can be turned on and off
at the same time.
Figure 3
Notes on Controller Transfer of Display Data
Since the LC75833E, LC75833W, and LC75833JE accept display data divided into three separate transfer operations,
we recommend that applications transfer all of the display data within a period of less than 30 ms to prevent observable
degradation of display quality.
