P2 full-color LED display has a real-time display, screen projection is adjustable, picture size can be selected at will, and window picture-in-picture function, rich colors, high saturation, high resolution, is a high-frequency LED full-color display screen. It adopts nonlinear correction technology, distributed scanning technology and modularization technology, which has high reliability and stability, and is easy to operate. It can be played by computer or asynchronously, and various playback effects can be designed by themselves . The system is easy to operate and convenient. simple. As a typical small-pitch full-color LED display, P2 full-color LED display has a broad market advantage. So, what advantages does P2 full-color LED display to have in the US market?
1. High maintenance: Compared with traditional SMD packaging, our company's small-pitch display adopts DCOB packaging and technology, which can be wiped and cleaned directly; DCOB lamp beads can with stand vertical pressure of 100N/cm2, which effectively solves small-pitch transportation and installation The phenomenon of bumping off the lamp and falling off of the pad during the process can reduce the maintenance cost of the user.
2. High stability: DCOB technology can effectively be anti-static, anti-corrosion, and anti-oxidation. Compared with SMD discrete devices, DCOB has a lower dead pixel rate with small spacing and long screen life. Users no longer need to store and transport at high temperatures and humidity. And operating environment concerns.
3. Wide color gamut: using RGB three-primary color imaging technology, a broadcast color gamut higher than 115% NTSC, 281 trillion colors, and surface reflective treatment, good light directivity, reduce surface glare, and color performance is more delicate and rich , The horizontal and vertical viewing angles are 170°/170°.
4. Good heat dissipation: The positive and negative poles of the DCOB chip are directly connected to the circuit on the PCB board, the heat conduction path is short, there is no intermediate medium, the thermal resistance is small, the heat dissipation effect is better than the SMD discrete device, and the power saving effect is good.
