Note (1) Test Equipment Setup
The measurement should be executed in a stable, windless and dark room between 30min after lighting the back light at the given temperature for stabilization of the back light. This should be measured in the center of screen.

a. Test image : 100% full white pattern with a test pattern as below
b. Test pattern : Squares, 40mm by 40mm in size, filled with 255, 225, 195, 165, 135 and
105 grays steps should be arranged at the centerof the screen.

-1
gray step : move a square of 255 gray level should be moved into the center of the
screen and measure luminance and u’ and v’ coordinates.
- Next gray step : Move a 225 gray square into the center and measure both luminance and coordinates, too.
d. Test evaluation
Δu' v'= (u' - u' ) + (v' - v' )
Where A, B : 2 gray levels found to have the largest color differences between them
i.e. get the largest ȟu’ and ȟv’ of each 6 pair of u’ and v’ and calculate the ȟu’v’.
