*1 This voltage should be applied to VDD – V5.

Voltages applicable to V1, V2, V3 and V4 are as follows:

V1 = VDD – 1/4 (VDD – V5)

V2 = V3 = VDD – 1/2 (VDD – V5)

V4 = VDD – 3/4 (VDD – V5)

*2 This voltage should be applied to VDD – V5.

Voltages applicable to V1, V2, V3 and V4 are as follows:

V1 = VDD – 1/5 (VDD – V5)

V2 = VDD – 2/5 (VDD – V5)

V3 = VDD – 3/5 (VDD – V5)

V4 = VDD – 4/5 (VDD – V5)

*3 The relation of VDD > V1 > V2 ≥ V3 (=V3') > V4 > V5 ≥ VSS must be kept.

Æ Low)

LCD driving voltage can be adjusted by varying V5.

However, V5 cannot be used under VSS voltage.
