Measuring Device
TOPCON BM-7,Measuring Field:1°
Tektronix Digital Oscilloscope
Measuring Point
Center of display, same as Method of Brightness Measurement
Method of Measuring
Set LCD panel toθ=0°,and φ=0°.
Input white→black→white to display by switching signal voltage.
If the luminance is 0% and 100% immediately before the change of signal voltage,
then τr is optical response time during the change from 90% to 10% immediately after
rise of signal voltage, and τd is optical response time during the change from 10% to
90% immediately after decay of signal voltage.
