Qiangli Q1.8 MPro - P1.8 Indoor GOB LED Module, 3840Hz

The Qiangli Q1.8 MPro (item Q1.8-43S-H-1515) is a 1.8 mm pixel pitch indoor full-colour LED module built on 1R1G1B GOB1515 packaging. GOB encapsulation seals the lamp surface against moisture, dust and impact while keeping single-lamp maintainability, making it well suited to high-traffic indoor installations, control rooms, retail and rental use. Lamps and driver ICs sit on the same PCB with constant-current 1/43 scan driving, delivering 3840 Hz refresh, 13-14 bit grayscale and 4398 billion colours with no afterimage, no caterpillar effect and low surge. Each 320 x 160 mm module carries a 172 x 86 pixel array at 288906 dots per square metre and mounts magnetically to a 640 x 480 mm front-service cabinet.
