Note (9) Color Grayscale Linearity

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 center⑤ of the screen.

c. Test method

st

-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.

www.jxlcd.com

- Next gray step : Move a 225 gray square into the center and measure both luminance and coordinates, too.

d. Test evaluation

∆u'v'= (u' -u' ) +(v' -v' )AB

Where A, B : 2 gray levels found to have the largest color differences between them

i.e. get the largest Δu’ and Δv’ of each 6 pair of u’ and v’ and calculate the Δu’v’.
