The next example is for Figure 25-6 which is a 1/4 MUX, 1/3 BIAS waveform. For this example,
the values 3, 2, 1 and 0 will be assigned to V
DC voltage, RMS voltage and discrimination ratio calculations are shown in
Example 25-4:
As shown in these examples, static displays have excellent contrast. The higher the multiplex
ratio of the LCD, the lower the discrimination ratio, and therefore, the lower the contrast of the
display.

and BIAS.
As the multiplex of the LCD panel increases, the discrimination ratio decreases. The contrast of
the panel will also decrease, so to provide better contrast the LCD voltages must be increased
to provide greater separation between each level.
