LCD driver for low multiplex rates

Product specification

OM4068

Backplane outputs

The LCD drive section includes three backplane outputs (BP1 to BP3) which should be connected directly to the LCD.

The backplane output signals are generated in accordance with the selected LCD drive mode. If less than three

backplane outputs are required the unused outputs should be left open-circuit. In 1 : 2 multiplex drive mode, BP3 is set

to 1⁄2VLCD. In static drive mode BP3 and BP2 are set to VSS.

LIMITING VALUES

In accordance with the Absolute Maximum Rating System (IEC 134).

HANDLING

Inputs and outputs are protected against electrostatic discharge in normal handling. However, to be totally safe, it is

desirable to take normal precautions appropriate to handling MOS devices (see “Handling MOS Devices”).
