= 5 V and 9 V, Ta = 25 ± 3°C)
Change the bus data and set the sub-contrast to the maximum.
Input signal 2 to pin 54 and gradually increase the amplitude.
When pin 13's picture period is clipped, measure the picture period
amplitude of pin 13
Apply an external power supply to pin 54 and gradually decrease the
voltage from 3.7 V.
When their picture periods are clipped, measure the picture period
amplitudes of pins 13, 14, and 15.
Input the TG7 stair-step signal to pin 54.
Adjust the unicolor data so that the pin 13 stair-step output signal is 1.25
V
When the stair-step signal APL is changed from 10% to 90%, measure
the voltage change at point A in the diagram below.
Repeat steps 1) to 3) above on pins 14 and 15.
