1. Measuring conditions are as given in Supplementary Table.
2. Measure the output at T.P25 (30 or 35) with a voltmeter.
The measured value is called V
OR7'
(V
OG7'
or V
OB7'
), and is
treated as V
B2
.
3. To obtain brightness control relative characteristics (
V

),
calculate the difference in the output between the channels,
using V
OR7'
, V
OG7'
, and V
OB7'
.

1. Measuring conditions are as given in Supplementary Table.
2. SG1
SG2 and SG3 are input. The amplitude of the waveform
output at T.P25 (30 or 35) is measured.
3. Supposing that the measured value is treated as amplitude V
OR1
(V
OG1
or V
OB1
) when SG1 is input, as V
OR8
(V
OG8
or V

) when
SG2 is input, or as V
OR9
(V
OG9
or V
OB9
) when SG3 is input,
frequency characteristics F
C1
and F

are calculated as follows:
4. Frequency relative band widths
F

1. Measuring conditions are as given in Supplementary Table.
2. Input SG2 (or SG3) to pin 13 (R-ch) only, and then measure the
waveform amplitude output at T.P25 (30 or 35). The measured
value is called V
OR
, V
OG
and or V
OB
respectively.
3. Crosstalk C.T. 1 is calculated by the equation below:
C.T.2 Crosstalk2 (f=50MHz)
C.T.2' Crosstalk2 (f=130MHz)
1. Change the input pin from pin 13 (R-ch) to pin 8 (G-ch), and
measure the output in the same way as in C.T.1, C.T.1'.
2. Crosstalk C.T. 2 is calculated by the equation below:
C.T.3 Crosstalk3 (f=50MHz)
C.T.3' Crosstalk3 (f=130MHz)
1. Change the input pin from pin 13 (R-ch) to pin 3 (B-ch), and
measure the output in the same way as in C.T.1, C.T.1'.
