MEASUREMENT METHOD
1) Measure t_dON and t_dOFF using the signal input to pin 34 (FBN-IN) (A
below) and the signals output from pins 13, 14, and 15 (B below).

1) Input signal 1 (f = 100 kHz, picture period amplitude = 0.2 V_p-p) to pin 54.
2) When the subaddress (0F, sub-contrast) data are changed to the
maximum (8F), the center (88), and the minimum (80), measure the

3) Calculate the maximum and minimum amplitude ratios in relation to the
sub-contrast center in decibels.

Range
1) When the R cutoff (subaddress (08)) data are changed to the maximum
(FF), the center (80), and the minimum (00), measure the picture period
amplitude of pin 13 and calculate the change in maximum and minimum
from the center.
