To know more about the 8 factors for choosing led display for outdoor advertising. In the last article, introduced three key factors that determine a high-quality Outdoor LED screen. It is determined not only by three factors, but also for PCB boards, kits, screws, cabinets, glues, cables, power cords, and processes.

1. [Yuchip] takes you 3 minutes to learn about 8 factors for choosing a
high quality Outdoor LED screen
As technology continues to mature, LED video screen is becoming more widely used,
both indoor and outdoor applications are growing, airports, shopping centers, highways, sports
fields, hotels, hospitals, business centers, and bus stops. With the rapid increase in application
requirements, led advertising display has become the market leader by virtue of its clear visibility
in the sun. Accordingly, the rapid increase in demand in this market will also strongly promote the
expansion of the LED video screen market. The development of the New Media for Outdoor LED
Advertising in the 21st century, the market prospects areimmeasurable.
In the last article, I introduced three key factors that determine a high-quality Outdoor
LED screen. It is determined not only by three factors, but also for PCB boards, kits, screws,
cabinets, glues, cables, power cords, and processes. The choice of these eight items, then I w ill
introduce the criteria for these eight choices:
1, PCB board, in fact, PCB board is everywhere in our lives, that is, glass fiber and resin,
the combination of the two, hardened into a heat-insulating insulation and not easy to bend the
board, the surface of the PCB will cover a Layer copper, in order to transmit signals, the general
use of indoor led display screen and outdoor led display screen most of the 2 layers or up to 8
layers, the thickness of the PCB is also very important, generally used 1.6mm, outdoor market
There are 1.2mm or even thinner. If the PCB is thicker, the wiring will be better. The circuit will be
divided into several layers. The more layers, the more complicated the process, the better the
heat dissipation, the lower the failure rateand the longer the service life.
2,LED module frame:LED video screen How many problems are related to LED Suite,
what is the cause of the black screen color abnormality? Why is the kit materialunstable?
Generally speaking, the advantages of the LED module frame can be distinguished from

2. the following three aspects:
1) Appearance: The appearance of the LED Suite mainly includes whether the color of the
mask is consistent, the color of the ink, whether the text is clear, whether there is any repairing
phenomenon, and whether the appearance is scratched. If the black screen color is abnormal,
the difference in color of the kit mask results in a color difference when the screen is black.
2) Control of size, whether the external dimensions are controlled according to the
tolerance range, the outer dimensions of the product is one of the important factors that directly
affect the splicing. The size is well grasped, and the splicing effect of the product will be good.
3) Structure: In the splicing process, the strength of the structure plays an important role.
Whether the practicability meets the requirements of the LED module, it has high strength
impact resistance, high toughness, and at the same time has waterproofness. The mask is
thermally deformed and will affect the display. The material or size problem of the mask causes
the mask to bulge during the thermal expansion and contraction process, and the deformed
mask bulges to block the display effect, causing the deformation to open the lamp foot and the
soldering of the lamp, and the lamp bead shift causes the dead light phenomenon.
3,Screws, stainless steel can resist the corrosion of air, water, acid, or other media,
stainless steel screws are not easy to rust, some screws are acid-resistant, but not necessarily
rust-proof. If the screw rusts, the consequences are: 1) maintenance is not possible; 2) rusting
and then raining down will damage the LED lights.

3. 4,LED cabinet: The thickness of the LED cabinet itself is 1.2mm. Waterproof is an
important indicator of the outdoor led display screen. For example, IP65, the first number
indicates the dustproof rod, and the second number indicates the waterproof rod. The higher the
number, the protection rod The higher. Some LED cabinets use a polyurethane coating to give the
cabinet a stronger wear resistance, water resistance and heat dissipation. Now that our LED video
screen is used more and more, the LED cabinet materials used in different scenes will be different.
Next, I will introduce some options about LED cabinet materials:
1) Iron cabinet: This kind of LED display cabinet production process is relatively backward,
which is slightly different from the sealed cabinet and simple cabinet. The waterproof level on
the front of the sealed cabinet is IP65, and the waterproof level on the back is IP63 suitable for
outdoor fixed screen installation, waterproof, protection and stability. The waterproof level of the
simple cabinet front is IP65, and the back is not waterproof. It is suitable for the Semi-outdoor
LED screen. This kind of cabinet is more convenient, quick and practical in installation, waterproof,
heat dissipation and maintenance.
2) Die-cast aluminum cabinet: It is mainly used for stage display and colorful background.
It has been promoted from the original sheet metal cabinet to the die-cast aluminum cabinet
through the development of recent years. The weight is getting lighter and the structure is more
and more reasonable. Basically, it can realize seamless splicing. It is optimized from all aspects of
structural performance, high cabinet splicing degree, and easy to disassemble and maintain. With
strong contrast, soft color, the whole screen looks very beautiful.
3) Aluminum cabinet: The weight of aluminum is much lighter than that of iron. The
aluminum cabinet has a closed box with a rear-facing convection cooling fan. The electronic
components of the aluminum cabinet are in the sealed environment of the cabinet, which
reduces the exposure of the electronic components to the air. The probability of salt spray
erosion damage, the corrosion resistance of outdoor aluminum is stronger to avoid damage to
the screen caused by rain, and the service life of the whole screen is improved.

4. 5, Glue: led video screen filling performance requirements for most applications in the
outdoor environment, so the most important performance requirement is "weather resistance" is
mainly reflected in the application of potting glue, suitable for a variety of environments, such as:
constant high temperature, Constant low temperature, constant moderate outdoor rain,
sunshine, snow and so on. It is UV-resistant for special applications and has good adhesion,
flexibility, insulation and water resistance after curing.
6,Cable: Generally, the cable used has butterfly buckle and plug. The butterfly buckle will
cost more than the plug. The cable will fall off during transportation.

5. 7,Power cord: The power cord and signal cable that can quickly connect two cabinets are
air plugs. You can directly connect the power cord without screwing. It is mainly used for led
rental display. Now the power cords we use are pure copper. The conductivity and consumability
of copper are the best, because the thickness of the copper wire is different, the power it
receives is different. The thicker the copper wire, the greater the conductivity, the greater the
power it receives, and the elasticity index of copper. The aspect is relatively high, and it is not
easy to bend, the stability is good, the corrosion resistance and oxidation resistance, the thicker
the copper wire carries the greater current, the conductivity, the safety is high, the failure rate is
low, if the fine copper wire is used for the carrier flow It is fixed, and once the actual current
exceeds a fixed value, it will cause the wire to overheat and burn out.
8,Process: The flatness of the structure surface directly affects the flatness of the surface
screen after the installation of the led video screen, which has a very important influence on the
display effect. To ensure the flatness, the surface frame and the LED display cabinet need to be
completely combined in the welding process. In order to ensure the flatness of the welding, each
cabinet must meet strict requirements during assembly to ensure that each cabinet achieves the
best results. The design of the cabinet structure allows us to increase the convenience during
installation and maintenance, and double the work efficiency.

6. In summary, I personally think that choosing a high-quality outdoor led display screen is a
relatively important point. In this era full of opportunities and challenges, some people will stop
to face the elimination, and some people dare to create a leader. Yuchip The trend of the vertical
direction of the led video screen is becoming more and more obvious, and will continue to rise to
provide users with valuable high-quality led advertising display, which will better bring the user a
different LED video screen.
In the next article, I will share the requirements for the Outdoor LED screen in various
application sites, such as how the video source is provided (with synchronous or asynchronous
control), installation location (hotel, bank door, taxi top) , exhibition, light pole screen) resolution
requirements, pixel points, brightness...etc., above are some of my personal opinions on
choosing a high quality outdoor led display screen. If you have any good comments or
suggestions, please feel free to contact us. I look forward to our common growth.
