PCA2117

Automotive LCD driver for character displays

It is important to match the module properties to those of the driver in order to achieve

optimum performance.

8.4.7 LCD drive mode waveforms

The PCA2117 contains 18 row and 100 column drivers, which drive the appropriate LCD

bias voltages in sequence to the display and in accordance with the data to be displayed.

R16 and R17 drive the icon rows. Unused outputs should be left open.

The bias voltages and the timing are automatically selected when the number of lines in

the display is selected. Figure 27 to Figure 29 show typical waveforms.
