First, whether the indoor LED display can
be changed to outdoor screen:
1, brightness limit: indoor LED display
brightness requirements are not high, the main use is dynamic scanning circuit,
but the outdoor LED screen for brightness requirements are relatively high,
because it is a static scanning circuit, the hardware difference between the
two is relatively large. Dynamic scanning is mainly in order to save the
hardware cost of the display, the number of driver chips used is more than ten
times different, so this will greatly determine the brightness of the indoor
LED display is relatively low, generally between 1600cd/㎡, only suitable for indoor use.
2, waterproof restrictions: indoor LED
display structure requirements are basically not waterproof, even waterproof is
a simple waterproof treatment, and outdoor LED display on the waterproof
requirements are very high, because in the outdoor often encounter wind and
rain thunder, so in the production of the cable and box and other waterproof
treatment, in the box structure itself requirements will be different.
3. Viewing
distance limit: Indoor LED display requirements are close to the viewing
distance, the model is generally between P0.8, P1.5, P1.75, P2, P3 P4, the area
is relatively not too large, generally within 100 square meters, while the
outdoor LED display requires a relatively far viewing distance, the model is
generally between P5 and P10. Because the outdoor screen is usually relatively
large, it is generally more than 40 square meters.
Second, what elements should outdoor indoor
LED display have:
1, high-definition display effect better
display advertising screen
Outdoor HD full-color LED display as the
main carrier of video advertising transmission, you need to have a
high-definition display effect. This includes high resolution, high brightness,
high contrast, etc., high resolution ensures that the advertising picture of
high quality can be well presented; The high brightness ensures that the picture
can be clearly displayed under direct sunlight; High contrast is a strong
guarantee that the color of the picture is uniform and the image is delicate.
2. Large viewing Angle covers a wide area
The main task of outdoor indoor LED display
is to advertise and promote the image, therefore, let more audiences see the
picture is the primary goal of outdoor high-definition indoor LED display,
using a large Angle of view design. Covering a wide range of viewing angles.
3. Low energy consumption, energy saving
and emission reduction
Outdoor indoor LED display must be called
upon by the government, and energy saving and emission reduction must be
implemented as an important standard in manufacturing, including product power
consumption, product scattering performance and the steel structure required
for product installation.
4, high protection level
Usually, the outdoor LED display
installation area is large, and most of them are installed in densely populated
places, so pay special attention to the protection level of the display,
especially in the southeast coastal areas where typhoons often log in. Its
design should consider the solid foundation of the steel structure, wind load,
waterproof, dustproof, moisture and many other factors, the protection level should
be IP65 and above, extend the service life of the indoor LED display and
enhance reliability.
5. Lightning protection and grounding to
prevent leakage accidents
Do a good job of lightning protection, the
LED body and shell should have good grounding measures, and consider its
grounding form according to whether the display is set independently or
attached to the external wall of the building.
At the same time, the integration of electronic components in the outdoor full-color LED display is high, and the sensitivity of its anti-interference requirements are becoming higher and higher, in order to minimize electromagnetic interference, lightning protection devices should usually be installed on the display screen and buildings.
Third, summer outdoor full color LED
display water treatment solution:
1, at a fast speed with cloth or towel to
absorb a lot of water, the next step of drying, pay attention to the need to
power off operation.
2, after drying the indoor LED display
continue to power aging, the specific steps are as follows:
Phased operation: the full white brightness
of the screen is 10%, and the power aging time is 8-12 hours.
(1) The full white brightness is 30%, and
the time is 12 hours
(2) Full white brightness is 60%, and the
time is 12-24 hours
(3) Full white brightness is 80%, and the
time is 12-24 hours
(4) Full white brightness is.... The time
is 8-12 hours
3, the completion of the above steps
basically no problem, but in the process of operation need to pay attention to
the following points:
(1) When the indoor LED display is flooded,
corresponding measures should be taken in time, and do not delay time.
(2) The indoor LED display with water is
quickly dried.
(3) Do not put the screen body that has
been flooded into the aviation case, which may cause damage to the LED lamp
beads.
