Philips Semiconductors
LCD driver for low multiplex rates
FUNCTIONAL DESCRIPTION
The OM4068 is a low-power LCD driver designed to
interface with any microprocessor/microcontroller and a
wide variety of LCDs. It can drive any static or multiplexed
LCD containing up to three backplanes and
up to 96 segments.
Product speci?cation
OM4068
The display configurations possible with the OM4068
depend on the number of active backplane outputs
required; a selection of display configurations is given in
Table 1.
A typical system (MUX 1 : 3) is shown in Fig.4.

Fig.4 Typical system configuration.
The host microprocessor/microcontroller maintains the
3-line bus communication channel with OM4068.
The internal oscillator requires no external components.
The appropriate intermediate biasing voltage for the
multiplexed LCD waveforms are generated on-chip.

The only other connections required to complete the
system are to the power supplies (V SS , V DD and V LCD ) and
suitable capacitors to decouple the V LCD and V DD pins to
V SS .
