Application Section
The values of the resistors in the gamma correction curve
are calculated such that a current of 1 mA flows in the
resistor chain.

Where x is the index for the corresponding gamma voltage
and has a range of 1 to 18.
Using these formulas the resistor values in Table 1 are
calculated. High accuracy resistors values can be realized
using 0.1% resistors. A method for fine-tuning the resistor
value is to combine two resistors in series.
