Note)

1. Contrast Ratio(CR) is defined mathematically as

Surface Luminance with all white pixels

Contrast Ratio =

Surface Luminance with all black pixels

2. Surface luminance is the center point across the LCD surface 50cm from the surface with all pixels

displaying white. For more information see FIG 1.

3. The variation in surface luminance , The Panel total variation (δ

WHITE) is determined by measuring LN

at each test position 1 through 5, and then dividing the maximum L

N of 5 points luminance by

minimum L

N of 5 points luminance. For more information see FIG 2.

WHITE = Maximum(L1,L2, … L5) / Minimum(L1,L2, … L5)

4. Response time is the time required for the display to transition from white to black (rise time, Tr

R) and

from black to white(Decay Time, Tr

D). For additional information see FIG 3.

5. Viewing angle is the angle at which the contrast ratio is greater than 5. The angles are

d e t e r m i n e d

for the horizontal or x axis and the vertical or y axis with respect to the z axis which is normal to the

LCD surface. For more information see FIG 4.
