OP7100

Liquid Crystal Display (LCD)

The 240 × 320 ¼ VGA LCD supports both graphics and text. Automatic
contrast control is built in so that the contrast, once set, does not drift as
the OP7100 warms up or is moved.

Figure 3-4 provides a block diagram of the LCD control and RAM circuits.

Figure 3-4. Block Diagram LCD Control and Memory

The LCD is connected to the OP7100
circuit board through header J1 or J3
on the circuit board.

Contrast Adjustment

Figure 3-5 shows the location of the
manual contrast adjustment. This con-
trast adjustment is the factory default for
the OP7110. The OP7100 is configured
with software contrast control as the fac-
tory default. With software contrast con-
trol, the contrast level may be set via a
software function call. Since it is hard
to guess the correct level in software,
buttons defined on the OP7100 touch-
screen and in software can be used to
adjust the contrast. A user-supplied key-
pad can facilitate this type of software
control for the OP7110.
