Liquid Crystal Display Drive Voltage Circuit (HD61604)
What is LCD Voltage
HD61604 drives liquid crystal display using four levels of voltages (Figure 21); VDD, V1, V2, and V3
(VDD is the highest and V3 is the lowest). The voltage between VDD and V3 is called VLCD and it is
necessary to apply the appropriate VLCD according to the liquid crystal display. V3 always needs to be
supplied regardless of the display duty ratio since it supplies the voltage to the LCD drive circuit of
HD61604.
Connecting R2–R5 in series between VDD and VSS (Figure 22) generates V or VLCD by using the
resistance ratio to supply these voltage to pins V1, V2, V3, C2–C4 are the smoothing capacitors. Connect
a trimmer potentiometer for R5 and change its resistance value to control the contrast.
