• Manufacturer Part Number: lc75884e
• Description: 1/4 Duty Lcd Display Drivers With Key Input Function
• Manufacturer: Sanyo Semiconductor Corporation

Sample Application Circuit 4
1/3 bias (for use with large panels)
Note: *8. Add a capacitor to the logic block power supply line so that the logic block power supply voltage V
Notes on transferring display data from the controller
The display data (D1 to 220) is transferred to the LC75884E/W in four operations. All of the display data should be
transferred within 30 ms to maintain the quality of the displayed image.
*9. If the RES pin is not used for system reset, it must be connected to the logic block power supply V
*10. The DO pin, being an open-drain output, requires a pull-up resistor. Select a resistance (between 1 to 10 kΩ) appropriate for the capacitance of
logic block power supply voltage V
