I still would like to share with you some knowledge about how to
judge a good LED display from appearance
a. The screen surface should be very flatã
b. The horizontal viewing angle should be very large like 160 degrees
without seeing module blocks
c. Look at screen in the front side, there should not have any
obvious gaps between modules and cabinets
d. When the LED display show white color , the color uniformity
should be good which is pure
e. when the LED display is not lighting on, also should not see "
Mosaic" problem
If you take all above points into consideration, you will surely
find the difference between our LED displays and other companies'
LED chip or LED lamp quality is essential , but that do not decide
the whole LED display's quality . Every material selection, design,
workmanship, quality control, some small detailed combined all
together will decide the LED display's quality.
