• Manufacturer: Mitsumi Electronics, Corp.

ELECTRICAL CHARACTERISTICS TEST METHOD
1. Because a description of signal input pin and pulse input pin
Sub contrast voltages V4, V9 and V14 are always set to the same
voltage, therefore only V4 is referred to in Supplementary Table.
I
Measuring conditions are as listed in Supplementary Table.
Measured with an ammeter At test point A when SWA is set to b.
Vomax Output dynamic range
Voltage V19 is varied as described below:
1. Decrease V19 gradually while inputting SG5 to pin 13 (8 or 3).
