(8) LCD panel drive

(8-1) LCD driving voltage generation circuit

LCD driving voltage generation circuit generates LCD driving bias voltages V0, V1 and V2. It adjusts the

voltage by 8 steps electrical volume from VDD and allots the voltage to V0, V1 and V2 by

resistor-voltage-dividing as shown in below.

VDD, V0, V1 and V2 terminals requires external capacitors for bias voltage stabilization for display quality.

These values of capacitors should be fixed in accordance with evaluation in the application.

When the E.V.R. is not used, V0 terminal should connect to VDD.

When the NJU6535 operates as 1/2 bias operation, V1 terminal should connect to V2.
