Product overview: P20 outdoor plug-in dual color LED display module has the characteristics of high waterproof, high luminous rate, long service life, etc. The display effect is good, the color is bright, the brightness is high, the viewing distance is far, it is very suitable to be used as the traffic variable information screen and outdoor advertising screen. P20 dual color LED display module is widely used in the traffic guidance and related application fields of expressway, tunnel, urban road, road network dense section of main highway, urban road, street, airport, wharf, station, etc. Features: 1. High brightness: LED with ultra-high brightness is used, which is still visible in the long distance under the strong sunlight; 2. High uniformity: ultra-high color uniformity of display screen, more delicate display screen; 3. Good flatness: the flatness of module installation surface is required to be controlled within plus or minus 0.1mm;
4. Patent mask: unique dip angle design, reduce waste and improve effective viewing angle; 5. Strong reliability: adopt multiple scanning technology and modular design technology, with higher reliability and stability; 6. Circuit board stability: circuit board adopts wave soldering technology, with green oil oxygen barrier, which prevents the line from being wet, oxidized and improves service life; 7. Over three anti paint: Protection The protective circuit board and its related equipment are corroded by the environment and have good high temperature resistance. After curing, they form a transparent protective film, which has superior insulation, moisture-proof, leakage proof, shockproof, corrosion-proof, aging proof, corona resistance and other properties. 8. Waterproof glue filling: automatic glue filling machine is used to ensure that the glue filling of the module is even, smooth and waterproof. 9. Strict inspection: product Through a series of strict inspection and testing, such as raw material testing, production process inspection, finished product aging testing, etc.
