Universal LCD driver for low multiplex rates

(3)

Using Equation 3, the discrimination for an LCD drive mode of

• 1:3 multiplex with 1

⁄2 bias is

• 1:4 multiplex with 1

⁄2 bias is

The advantage of these LCD drive modes is a reduction of the LCD full scale voltage VLCD

as follows:

• 1:3 multiplex (1

⁄2 bias):

• 1:4 multiplex (1

⁄2 bias):

These compare with

when 1

⁄3 bias is used.

It should be noted that VLCD is sometimes referred as the LCD operating voltage.
