P4.81 SMD1921 Black Face Outdoor Led Screen Hire High Contrast High
Resolution 5500nit IP65
Advantages:
exceptional image quality, high brightness and auto adjustment according to environment, intelligent group management, easy and convenient.
Inner arc design support 0 to 6 degree straight screen and accurate splicing with creative and flexible styling.
The series products including 3.91mm, 4.81mm, 5.95mm, and 6.25mm pixel pitch, have the same structure and the same easy installation mode.
Lightweight, super thin, simple, plug and play operation, easy to use, IP65 waterproof,
Simple
Ultra lightweight and slim design: 8kg and 77mm modular panel: fewer cables, 1-in 1-out design plug and 1-in 1-out design signal cable;
1. Lightweight. Die-casting aluminum panel of 500x1000mm, each
panel weighs 13kg,it is convenient in transporting and installing
& saving labor cost, suitable for flow shows.
2. The LED cabinet design has a nice appearance and simple
structures.
3. The LED wall jointed correctly, being installed & dismounted
by one person without tool.
4. The LED display has humanized operating interface with breakdown
indicator
lights, easy to maintain
5. The LED screen brightness debugging and no damage to grayscale,
achieving the debugging technology for nice image.
1. Humanized brightness adjustment
The external sensor can adapt to the environment, and its playback
quality will not be affected by ambient light.
2. Single point of brightness and color temperature correction
technology
Guarantee of good consistency of display screen. Single point
correction technology is the core of LED display technology, it
allows hundreds of thousands of LED lights on the same panel to
glow uniformly, making the screen brightness and color temperature
highly unified.
3. Ultra high refresh rate
Intake five black screen picture stability without ripples, dealing
with the dynamic display screen, and the image edge is clear. With
good dynamic performance, the image information is restored
accurately, make the video screen clear fluid, bring good visual
enjoyment.
4. High Reliable Quality
Nationstar SMD1921 is best brand lamp in China market
MBI IC is most reliable IC in the market
G-Energy is most popular in Led Screen industry.
