2. LCD Driver Output Voltage Level

The relationship between the data bus signal, AC converted signal FR and LCD driver output voltage is as shown in the table

below:

2.1. Segment Mode

Note: There are two kinds of power supply (logic level voltage, LCD driver voltage) for the LCD driver. Please supply regular

voltage which is assigned by specification for each power pin.

That time "Don't care" should be fixed to "H" or "L", avoiding floating.
