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, or the relationship between signal

amplitude and the transmittance of the panels, are

measured by System II by inputting the same signal

correspond to the voltages which define 90%, 50%,

and 10% of transmittance respectively.

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

the diagram below.

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.
