LCD driver supply voltage
•
LCD driver power supply port when external power supply
is used.
When external power is used, voltages should
have following relations.
VSS<V4<V3<V2<V1<VLCD
•
VLCD, V1~V4 voltages are generated by voltage booster at
master mode operation under power circuit ON.
•
When internal power supply is used, capacitors must be
connected between VLCD, V1~V4 and VSS.
