P3.91 indoor full color LED screen in the United States has different price markets, which are mainly related to the packaging technology for making P3.91 full color LED screen. The technology for making P3.91 full color LED screen mainly includes In- Four packaging technologies: line (lamp) package, Surface mount (SMD) package, COB package, and Micro LED package. So, do you know which packaging technology is more expensive in the United States?
As far as I know, the price of P3.91 full-color LED display is the most
expensive style in the United States:
● Adopting SMD three-in-one technology,
so that the display has an ultra-wide viewing angle and better surface flatness
when in use;
● The average power is only 200W/m2, super energy saving;
●
Lightweight and ultra-thin screen design, the total weight of the box is only
7.3kg, which effectively saves freight costs;
● The flatness error of the
whole screen is less than 0.2mm, which can effectively eliminate the mosaic
phenomenon;
● Synchronous adjustment of color and brightness to make the
picture more delicate and lifelike;
● High contrast and high refresh rate, so
that there is no delay or smear phenomenon when the LED display shows the
image;
● The cabinet is designed with a suspended installation structure,
which makes the assembly process faster;
● The professional packaging and
protection of the air box play a good role in protecting the leased control
equipment.
The main reasons for choosing P3.91 full-color LED display in most occasions
are as follows:
P3.91 full-color LED display application lamp beads are SMD1921, and
its waterproof surface mount three-in-one adopts a subversive design of inner
white and outer black, which significantly improves the contrast of the
display.
Of course, the lamp beads must be matched with a high-grade PCB
circuit to make the product outstanding. In the P3.91 full-color LED display PCB
circuit design, the circuit and the green oil oxygen barrier can prevent the
circuit from being wet and oxidized, which fundamentally improves the product
service life and the horizontal and vertical viewing angle of 160°. The
environment with large drop is suitable for application.
It can protect the related equipment of circuit board machinery from
environmental erosion, and has good high temperature resistance. After curing,
it will form a transparent protective film, which has the properties of
insulation, moisture resistance, leakage resistance, dust resistance, corrosion
resistance, and aging resistance.
P3.91 full-color LED display is also an advantage in the field of
cabinets. The aluminum alloy cabinet structural design is very light and
beautiful, not easy to deform, and can be quickly assembled and flattened. It is
suitable for rental companies, car screens, mobile media screens and tourist
attraction guide screens. It can be installed on the column or wall to greatly
reduce the pressure of the screen on the steel structure.
The green energy-saving design reduces operating costs and also prolongs the service life of the P3.91 full-color LED display. The use of German low-power bright drive LEDs can save energy ≥20%, and mainstream power supplies can save energy ≥15%.
