Basic Measurement Conditions
In the Measurement system-1 (see Fig. 1 (a), (b)), calculate the reflectance factor by using the formula (1).
R = R (White) =
In the Measurement system-1 (see Fig. 1 (a), (b)), measure the reflectance factor of "White" and "Black"
respectively and calculate by using the formula (2).
CR =
In the Measurement system-2 (see Fig. 2), measure the white chromaticity. The illumination source and
viewing area are D65 and 2° respectively.
In the Measurement system-3 (see Fig. 3), measure the electro-optical response time.
In the Measurement system-1 (see Fig. 1 (c)), viewing area is defined by the area which makes the CR 2.
In the Measurement system-4 (see Fig. 4), measure the luminance and calculate using the following formula
(3).
In the Measurement system-4 (see Fig. 4), measure the luminance and calculate using the following formula
(4).
(1) Driving voltage
(2) Measurement temperature
(3) Measurement point
(4) Light source and viewing area
(5) Display "White": All R, G and B signal data are high (signal amplitude across the liquid crystal: ±1.0V).
Front light is turned off unless otherwise specified.
Lcfl = (Luminance (1) + Luminance (3) + Luminance (5) + Luminance (7) + Luminance (9))/5 …(3)
Flunif = Luminance (maximum spot)/Luminance (minimum spot) …(4)
Typical condition
+25°C unless otherwise specified.
One point on the center of the panel unless otherwise specified.
D65 and 2°
Display "Black": All R, G and B signal data are low (signal amplitude across the liquid crystal: ±4.5V).
