<Electro-optical Characteristics Measurement>

Basic measurement conditions

(1) Driving voltage

HVDD = 15.5V, VVDD = 15.5V

VVC = 7.0V, Vcom = 6.6V

(2) Measurement temperature

25°C unless otherwise specified.

(3) Measurement point

One point in the center of the screen unless otherwise specified.

(4) Measurement systems

Two types of measurement systems are used as shown below.

(5) Video input signal voltage (Vsig)

Vsig = 7.0 ± VAC [V]

(VAC = signal amplitude)

1. Contrast Ratio

Contrast Ratio (CR) is given by the following formula (1).

L (White)

CR =

... (1)

L (Black)

L (White): Surface luminance of the center of the screen at the input signal amplitude VAC = 0.5V.

L (Black): Surface luminance of the center of the screen at VAC = 4.5V.

Both luminosities are measured by System I.
