ELECTRICAL CHARACTERISTICS TEST METHOD
1. Because a description of signal input pin and pulse input pin
switch numbers is already given in Supplementary Table, only
external power supply switch numbers are included in the notes
below.
Sub contrast voltages V4, V9 and V14 are always set to the same
voltage, therefore only V4 is referred to in Supplementary Table.
I
CC
Circuit current
Measuring conditions are as listed in Supplementary Table.
Measured with an ammeter At test point A when SW1 is set to a.
Vomax Output dynamic range
Voltage V19 is varied as described below:
1. Increase V19 gradually while inputting SG6 to pin 13 (8 or 3).
Measure the voltage when the top of the waveform output at
T.P25 (30 or 35) is distorted. The voltage is called V
TR1
(V
TG1
or
V
TB1
). Next, decrease V19 gradually, and measure the voltage
when the bottom of the waveform output at T.P35 (30 or 25) is
distorted. The voltage is called V
TR2
(V
TG2
or V
TB2
).
2. Voltage V
T
(V
TR
, V
TG
and V
TB
) is calculated by the equation
below:
Use relevant voltages, depending on the pin at which the
waveform is output; specifically, use V
TR1
when it is output at
T.P25; V
TG1
, at T.P30, and V
TB
, at T.P35.
