(3) Segment Driver Basing on display data, segment drivers output LCD SEG driving signal. (4) Common Driver Common drivers output LCD COM driving signal. (5) Voltage Booster NJU6573 with a built-in Voltage Booster. The internal voltage booster generates up to 3xVCI voltage(Input:VCI Terminal, Output: VDCOUT Terminal). The boost voltage VDCOUT must not exceed 10.0V(VCIx3≤ 10V), otherwise the voltage stress may case a permanent damage to the LSI. When using the internal LCD power supply, connect the VDCOUT and the VDCIN. The VREF voltage is tripled to obtain the VREG voltage.(VREFx3=VREG) Ver.2013-01-08 -5- NJU6573 Preliminary (5) Bleeder Resistance Each LCD driving voltage (V1, V2, V3, V4) is LCD driving high voltage input to the V0 Terminal, generated by the E.V.R and high impedance bleeder resistance. LCD driving voltage generation circuit generates LCD driving bias voltages V0, V1, V2, V3 and V4. VREG, V0, V1, V2, V3 and V4 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.
