s Functional Description (continued)

• Relationship between input data values and output voltages (continued)

Apply the voltages for the γ correction to the pins VREF0 to VREF9.

The γ correction voltage input pins are divided into two groups: the high-level output control group and the low-level

output control group, and each group is connected in series with resistors. Each of these resistor series has a total

typical value of 14 kΩ.

This structure is shown in the figure. The typical values of the resistors are shown in parentheses.

Note that since these voltages are resistor divided internally, the voltages applied to the VREF pins should be applied

through a low-impedance circuit. If the voltages are directly applied by the resistor divider, the desired output voltages

may not result.
