Brightness
To follow Panel specification
Image size
Actual display size: Refer to 2.1 LCD PANEL spec.
Brightness uniformity
Set contrast at 100% and turn the brightness to get average above 300 nits at centre of the screen. Apply the Fig 1;
it should comply with the following formula:
Where B_max =Maximum brightness
B_min = Minimum brightness
Check Cross talk(s)
Apply Pattern 2. Set contrast and brightness at 100 %. Measure YA. Then output Pattern 3 and measure YB. The
cross talk value:
White Color adjustment
There are three factory preset white color 9300K, 6500 and sRGB align by FGA function. Apply full gray 64 pattern,
with brightness in 100 % position and the contrast control at 50 % position. The 1931 CIE Chromaticity (color
triangle) diagram (x, y) coordinate for the screen center should be:
