Unless otherwise specified, this specification is defined
under the following conditions.
(1) Input signal : As defined in 3.3, follow panel resolution, signal sources must have 75 ohm output
impedance.
(2) Luminance setting : controls to be set to 300 nits with full screen 100 % duty cycle white signal

4.2
Brightness
Follow Panel specification.
4.3
Image size
Actual display size : Follow panel spec.
4.4
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:
( B_max - B_min )
X 100% > 75%
B_max
Where B_max = Maximum brightness
B_min = Minimum brightness
4.5
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 :
ABS ( YA - YB )
X 100% < 1.5 %
