MEASUREMENT METHOD
(1) Apply a rainbow color bar signal to pin 39.
(2) Measure the amplitude of RGB output signal at pin 19, 20 and 21 when the data
of sub-address (03) is set (7F). (V_UNImax)
(3) Measure the amplitude of RGB output signal at pin 19, 20 and 21 when the data
of sub-address (03) is set (40). (V_UNIcen )
G_UNIcen = 20ℓog (V_UNImax / V_UNIcen)
(4) Measure the amplitude of RGB output signal at pin 19, 20 and 21 when the data
of sub-address (03) is set (00). (V_UNImin)
G_UNImin = 20ℓog (V_UNImax / V_UNImin)
(1) Apply a rainbow color bar signal to pin 39.
(2) Adjust the data of sub-address (01) so that the 6th bar of B output signal at pin
21. (θ_TNTcen)
(3) Measure phase change of B output signal at pin 21 when the data of
sub-address (01) is change from (00) to (7F). (∆θ_TNT)
(1) Apply a rainbow color bar signal to pin 39.
(2) Measure rising time of color signal at pin 19, 20 and 21. When the data of
sub-address (04) is set (60). (DTC)
(3) Measure rising time of Y signal at pin 19, 20 and 21 when the data of
sub-address (04) is set (00). (DTY)
t_V-C = DTY−DTC
