3840Hz high refresh studio/church installation black SMD2021 super thin front maintenance p4 led screen indoor
3840Hz high refresh studio/church installation black SMD2020 super thin front maintenance p4 led screen indoor
Product Advantages:
1) High refresh rate , high brightness and high contrast which make the screen without any delay and smear phenomenon
under directly sunlight.
2)Energy saving:low electric current,high-bright lamps,equipped with PFC switching power supply that save 30% electricty.
3)The brightness can be adjustable to meet the need of changing environment
4)Wide viewing angle: The horizontal and vertical viewing angles are so wide that it is suitable for wide horizontal
5)Environment protection, antistatic, dust-proof, good heat dissipation, cost-effective .
6)Error detection and monitoring:it can monitorthe inner temperature,voltage,cooling fans etc and error detection automatically.
7) High reliability: using distributed scanning technology and module design technology that make higher reliability and stability.
8) Steady and reliable system:with strong anti-interference ability and long service life that can continually work for over 24 hours, and it's easy to operate the system.
9) Favorable effect: using dot to dot calibration technology makes the image clearer and the layering stronger
10) Convenient installation and maintenance of display modules
