You'll find numerous LED show manufacturers
here in China. A lot of owners of factory, they've been involved within this
field for greater than ten years.
But the way to pick a suitable LED show.
perhaps can be a old subject. but as far as I know, a lot of close friends have
no idea about this before they came to China. I decide on the
word"suitable", not "good". since diverse client has
various requirement. excellent does not imply appropriate, but appropriate does
indicates good for you personally.( led lamp

it constantly regarded as a project if you
want buy a LED display. so you ought to possess a spending budget on it, one
hundred,000, 80,000 USD? one thing like this. Then, it really is the details
about your project, such as:
1. where will probably be the LED show
installed? indoor or outside?
two. what message content is required?
videos, images, or just characters?
3. what dimension will be your screen?
width, height?
four. what will likely be the minimal
viewing distance from your screen for the closest spectators?
five. what's the distance from LED screen
to control program?
six. what's the installation variety?
inlay, pole, or anything else?
right after these data, you are able to get
a general answer in the supplier. for example,you need an outside display for
ad displaying, viewing distance is about 17 meters, you prepare one hundred,000
USD for it, along with the supplier could recommend P16,Cree LED chips, 40
square meters. ok, this solution sounds excellent, then you could wanna check
the good quality, this really is most important for you personally. you do not
want commit one hundred USD to get a piece of paper. so, how to judge the top
quality, perhaps you can take into account based on under data(dmx512

Crucial Aspects:
1. Smoothness (plainness on surface)
Keep the smoothness within 1 millimeter to
insure the image not been curved.it is determined by assemble tech.
2. Brightness
For indoor LED show, it need to be greater
than 800cd/sq.m and for outside, it should be more than 1500cd/sqm. If
brightness also low, the image will be totally vague.brightness is determined
by LED lamps you adopt and also other variables
three. Viewing angle
generally speaking, for outdoor displays,
viewing angle for horizontal is about 110 degree, and for vertical is 90
degree. the larger the better.
4. White balance.
To show a pure white colour, the ratio of
RGB is three:6:1, wacth if there is blue or red colour in white color. This
factor mainly is dependent upon handle system and LED lamps
five. Colour restorable.
The colour on LED screen should consist
with display resources to keep an excellent image.
6. Malfunctions dot, mosaic
Make certain there is no dead dot and
mosaic on show
These factors are extremely critical when
pick a LED show, it is diffecult to upkeep for some unprofessional customers.( Dali controller
