Optical

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 (5)

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

(4) Measurement Setup:

Light Shield Room

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.
