Note 1: Definition of Contrast Ratio (CR):

The contrast ratio can be calculated by the following expression.

Contrast Ratio (CR) = L63 / L0

L63: Luminance of gray level 63

L0: Luminance of gray level 0

CR = CR (10)

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

Note 2: Definition of Response Time (TR, TF):

Note 3: Viewing Angle

The above “Viewing Angle” is the measuring position with Largest Contrast Ratio; not for good

image quality. View Direction for good image quality is 6 O’clock. Module maker can increase

the “Viewing Angle” by applying Wide View Film.

Note 4: Measurement Set-Up:

The LCD module should be stabilized at a 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.
