2. Optical Transmittance
Optical Transmittance (T) is given by the following formula (2).
White luminance
Luminance of light source
T =
×
100 [%] ... (2)
"White luminance" means the maximum luminance on the screen at the input signal amplitude V
AC
= 0.5V
on Measurement System
I
.
3. V-T Characteristics
V-T characteristics, or the relationship between signal
amplitude and the transmittance of the panels, are
measured by System
II
by inputting the same signal
amplitude V
AC
to each input pin. V
90
, V
50
, and V
10
correspond to the voltages which define 90%, 50%,
and 10% of transmittance respectively.
4. Response Time
Response time ton and toff are defined by
formulas (3) and (4) respectively.
ton = t1
tON ...(3)
toff = t2
tOFF ...(4)
t1: time which gives 10% transmittance of
the panel.
t2: time which gives 90% transmittance of
the panel.
The relationships between t1, t2, tON and
tOFF are shown in the right figure.
