and white strips in the middle or around are clear, while the adjacent strips
can be distinguished to pass the test;
Images of different gray rank levels can be distinguished easily with a
smooth transition, and the brightness transition can also be obtained from
the images. Gray rank of low level is not obviously lean to red or green, and
then the test is passed.
Images of different color rank levels can be distinguished easily with a

Press [Set] to enter pure color interfaces of green, blue, red, black and white.
Observe the LCD screen. Check bright point and dark point in the black and
white interfaces. Criterion for pass: bright point number is 0; number of
continuous dark point pair is ≤3, and no continuous dark point appears in the
image area; there are no three or more than three continuous dark point;
dark point defects number is ≤7, and number of dark points in the image area
is ≤2; point flash defects is 0; space between fail points is ≥5mm.
