(2) Definition of Contrast Ratio (CR):

The contrast ratio can be calculated by the following expression and figure below.

Contrast Ratio (CR) = L255 / L0
L255: Luminance of gray level 255

L 0: Luminance of gray level 0
CR = CR (1)

CR (X) is corresponding to the Contrast Ratio of the point X at Figure in Note (5).

(4) Luminance, Chromaticity and CCT Measurement

The LCD module should be stabilized at given temperature for 20 minutes to avoid abrupt temperature change
during measuring. In order to stabilize the luminance, the measurement should be executed after lighting
Backlight for 20 minutes in a windless room.
