(6-1) LCD driving volyage generation circuit

The LCD driving voltage generation circuit is consists of bleeder resistance and voltage follower.

This circuit generates LCD driving bias voltages V1 and V2 from input voltage terminal (VLCD-VSS). It is

generated by the bleeder resistance in IC, and after impedance is converted by the voltage follower, it is

supplied to the LCD driving circuit. The VLCD terminal requires external capacitors for bias voltage stabilization

for display quality as shown in below.
