2. Optical Transmittance
Optical Transmittance (T) is given by the following formula (2).
White luminance
T=
× 100 [%] ... (2)
Luminance of light source
"White luminance" means the maximum luminance on the screen at the input signal amplitude VAC = 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 VAC to each input pin. V90, V50, and V10
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.
