Segmented displays are used in a wide variety of
applications, ranging from meters to portable medical
devices to thermostats to exercise equipment.
PIC microcontrollers with integrated LCD drivers can directly
drive segmented displays with letters, numbers, characters
and icons. The main features of Microchip’s LCD portfolio
include:

Direct Drive for Segmented Displays
The LCD PIC microcontrollers support direct LCD panel drive
capability with no external components needed, lowering total
system cost. They have integrated voltage bias generation
which allows the MCU to generate the different voltage levels

that are required to drive the LCD segment pins and provide
good contrast for the display. The LCD MCUs support a range
of fixed and variable bias options as well as variable clock
inputs that enable the flexibility to work with many different
glass vendors.
Contrast Control
Software contrast control is a key feature using firmware to
either boost or dim the contrast of the display. Boost the
contrast up to VDD or beyond if you are using one of the
MCUs with an integrated charge pump. Software contrast
control allows the designer to vary the contrast on the
LCD to account for different operating conditions such as
temperature, lighting, and humidity. Also, software contrast
control can be invaluable for portable applications. As the
battery level starts to drop, the firmware can apply a boost to
the contrast helping extend the battery life while still seeing
a crisp image on the display.
