For the length of 16 to 240, the gamma correction curve has to
be calculated as follows:
Rev. 0 | Page 54 of 88
y
=
x
γ
where:
y
= gamma corrected output
x
= linear input signal
γ = gamma power factor
To program the gamma correction registers, calculate the seven
values for
y
using the following formula:

y
where:
x
(
n
16)
= Value for x along x axis at points
n
= 24, 32, 48, 64, 80, 96, 128, 160, 192, or 224
y
n
= value for y along the y axis, which must be written into the
gamma correction register
For example,
y
24
= [(8/224)0.5 × 224] + 16 = 58
y
32
= [(16/224)0.5 × 224] + 16 = 76
y
48
= [(32/224)0.5 × 224] + 16 = 101
y
64
= [(48/224)0.5 × 224] + 16 = 120
y
80
= [(64/224)0.5 × 224] + 16 = 136
y
96
= [(80/224)0.5 × 224] + 16 = 150
y
128
= [(112/224)0.5 × 224] + 16 = 174
y
160
= [(144/224)0.5 × 224] + 16 = 195
y
192
= [(176/224)0.5 × 224] + 16 = 214
y
224
= [(208/224)0.5 × 224] + 16 = 232
where the sum of each equation is rounded to the nearest
integer.
The gamma curves in Figure 71 and Figure 72 are examples only;
any user-defined curve is acceptable in the range of 16 to 240.
