P4 indoor full color LED display screen


P4mm is indoor small pixel pitch LED video display. It is more commonly used and technology developing matured comparing with P2.8 and P3. It has high definition and good image effect with big pixel density 62,500 dots/sqm. The usual lamps closing method of P4 is SMD3528 3in 1, with bigger chips than SMD2020, which can increase the brightness at some extent.
