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 center of the screen.
c. Test method
-1st 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
'u' v' = (u' A - u' B) 2 + (v' A - v' B) 2
Where A, B : 2 gray levels found to have the largest color differences between them
i.e. get the largest u' and v' of each 6 pair of u' and v' and calculate the u'v'.

Note (1) This product is DE only mode. The input of Hsync & Vsync signal does
not have an effect on normal operation.
(2) Test Point : TTL control signal and CLK at LVDS Tx input terminal in system
(3) Internal Vcc = 5.0V
(4) Best operation clock frequency is 72.33MHz(60Hz)
(5) Clock frequency = Frame frequency x TV(Typ) x TH(Typ)
(6) Max, Min variation range is at main clock Typ value (72.33MHz).
