LCD segment drive output.

Input of LCD drive voltage setting.

Supply the 1 / 3 ∗ VL3 voltage to VL1.

Supply the 2 / 3 ∗ VL3 voltage to VL2.

Supply the VDD or the zero to VDD

voltage to VL3 .

Direct drive Input.(High Active)

The drive time is set from the HT0

and HT1 terminals, and the drive

starts from a rising edge of the

direct drive Inputs.

LCD cells will be driven while the

direct drive Input remains high.
