LC75808E, 75808W
Sample Application Circuit 6
1/10 duty, 1/4 bias drive technique (for use with large panels)
Note:
*
6.
Add a capacitor to the logic block power supply line so that the logic block power supply voltage V
DD
rise time when power is applied and the
logic block power supply voltage V
DD
fall time when power drops are both at least 1 ms, as the LC75808E/W is reset by the VDET.
If a variable resistor is not used for display contrast fine adjustment, the V
LCD
4 pin must be connected to ground.
If the function of the INH pin is not used, the INH pin must be connected to the logic block power supply V
DD
.
The DO pin, being an open-drain output, requires a pull-up resistor. Select a resistance (between 1 k
to 10 k
) appropriate for the capacitance
of the external wiring so that signal waveforms are not degraded.

Notes on Transferring Display Data from the Controller
The display data is transferred to the LC75808E/W in four operations. All of the display data should be transferred within
30 ms to maintain the quality of the displayed image.
