1)
Change the G and B drive data to the value resulting from the adjustment
in step 1) of T20.
2)
Set the brightness to maximum, set the subaddress (0F) data to (30), and
set the subaddress (10) data to (20).
3)
Input signal 3 (f0 = 100 kHz, picture period amplitude = 0.23 Vp-p) to pin 1.
4)
Measure the picture period amplitude of pin 11 when the unicolor data
change to the maximum (7F), the center (40), and the minimum (00).
(vuCYMAX, vuCYCNT, vuCYMIN)
5)
Calculate the unicolor maximum and minimum amplitude ratios using
decibel conversion. (

6)
Repeat steps 3), 4), and 5) above, inputting the picture period amplitude
0.2 Vp-p to pin 80 and measuring pin 15.

1)
Measure the voltage of pin 1.
Set the brightness to maximum, set the subaddress (0F) data to (30), and
set the subaddress (10) data to (20).
2)
Input signal 3 (f0 = 100 kHz, picture period amplitude = 0.115 Vp-p) to pin 1.
3)
Measure the picture period amplitude of pin 11 when the color data are
changed to the maximum (7F), the center (40), and the minimum (01).
(vcCYMAX, vcCYCNT, vcCYMIN)
4)
Calculate the color maximum and minimum amplitude ratios for the center
using decibel conversion.
