2. Effective aperture ratio

Measure the luminances below on the screen in System I, and calculate the effective aperture ratio using

the following formula (2).

Luminance for panel with microlens

× (TFT aperture ratio) × 100 [%] ...... (2)

Luminance for panel without microlens

3. V-T characteristics

V-T characteristics, the relationship between signal

amplitude and the transmittance of the panels, are

to the each voltage which defines 90%, 50% and 10%

of transmittance respectively.

The angles of incidence for R, G and B are as shown

in the diagram below.

Green: Left:

7.75 ± 0.5°

7.75 ± 0.5°

4. Response time

Response time ton and toff are defined by

the 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.
