(d) LCD Driving Voltage Generation Circuits
The LCD driving bias voltage of V

internal bleeder resistance. And it is supplied to the LCD driving circuits after the impedance conversion with
voltage follower circuit.
As shown in Fig. 4, Five capacitors are required to connect to each LCD driving voltage terminal for voltage
stabilizing. And the value of capacitors C5, C6, C7, C8 and C9 are determined depending on the actual LCD
panel display evaluation.
