6. RELATIONSHIP BETWEEN INPUT DATA AND OUTPUT VOLTAGE VALUE
The relation between input data and output voltage are shown in Table 6−2, 6−3.
Any 3 major points V1 to V3 from the LCD panel γ-characteristics curve can be used as the external power supplies.
The relationship V0 to V4 external power supplies and γ-correction resistance is shown in Table 6−1, Figure 6−1.

This external power supply pins (V0 to V4) can customize the γ-correction voltage by selecting the desired voltage
from one of 250 divisions of the string resistor between VSS2 and VDD2, which generated γ-correction voltage. Note
that the voltage can be selected individually for both positive and negative polarity.
