Display Control and the INH Pin
Since the LSI internal data (the display data D1 to D264 and the control data) is undefined when power is first applied,
applications should prevent meaningless displays with the following procedure. First, set the INH pin low at the same
time as power is applied to turn off the display. This will set the S1/P1 to S8/P8, S9 to S66, and COM1 to COM4 pins
low. While the INH pin is held low, the control microprocessor should send the serial data. Finally, the application can
set the INH pin to high. (See Figure 3.)
Notes on Power Supply Sequences
Applications must observe the following sequences when power is turned on or off.
Power on: Turn on the logic power supply (V
DD
) first
→
then turn on the LCD driver power supply (V
LCD
).
Power off: Turn off the LCD driver power supply (V
LCD
) first
→
then turn off the logic power supply (V
DD
).
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.

Notes on Controller Transfer of Display Data
Since the LC75874E and LC75874W accept the display data (D1 to D264) divided into four separate transfer operations,
we recommend that applications make a point of completing all four data transfers within a period of less than 30 ms to
prevent observable degradation of display quality.
