A31W33128 Series
17.2.2 LCD Voltage Command Fine Adjustment control
Software control of 16 voltage levels adjustment of V5 voltage by set 4 bits of the data bus. It can adjust the LCD
contrast.
17.3 LCD Bias voltage
When use built-in LCD bias resistor, Software can control the 1/6.7, 1/5,1/4 bias ratio to match the characteristic of
LCD panel.
17.4 Voltage Follower
The voltage follower buffers the LCD bias voltage created by the built-in bias resistor, and supplies it to the LCD drive
circuit.
