1. Contrast Ratio

Contrast Ratio (CR4.0) is given by the following formula (1).

L4.0 (White)

CR4.0 = L4.0 (Black) ...(1)

L4.0 (White): Surface luminance of the TFT-LCD panel at VDD = 12.0V, VVC = 6.0V, VCOM = 5.7V and the

RGB signal amplitude VAC = 0.5V.

L4.0 (Black): Surface luminance of the panel at VAC = 4.0V.

Contrast Ratio (CR4.5) is given by the following formula (2).

CR4.5 =

L4.5 (White)

L4.5 (Black)

...(2)

L4.5 (White): Surface luminance of the TFT-LCD panel at the RGB signal amplitude VAC = 0.5V.

L4.5 (Black): Surface luminance of the panel at VAC = 4.5V.

The above luminosities are measured by System I.
