COB LED Video Wall COB LED’s waterproof, shockproof, static-free, anti-oil stain, excellent heat dissipation, wide view angle, signal/power backup, etc. features make it invincible for control center, conference, TV, subway, large scale events, education, medical diagnosis, advertising, etc. applications. Learn MoreCOB led video wall cab concise process minimizes failure factors and contributes to higher stability, larger heat dissipation area reduces chip overheat damage and extends the lifespan of LEDs.Strong protection circuit board, crystal particles, solder feet, and leads are fully sealed. , moisture resistance, anti-collision, prevention of pollution damage, and easier cleaning of the device surface. Color PerformanceCOB Realizes The Conversion From “Point” Light Source To “Surface” Light Source No pixel graininess; reduce the light radiation, moiré, suitable for close and long-term viewing IP-CHIP COBFli-chip COB is the process to die-bond the chip directly onto the PCB board, without wire bonding, the simplified process contributes to less defect creation factor. bringing to high black occupancy and reliability. Hassle Free Installation.16:9 ratio cabinet, no need to stretch the video source. Easy and efficient installation, Complete front service, Perfect design produces a uniform installation across any setting with vision seamless splicing tech, eliminating gaps between frames or cabinets. SUPER VIEWING ANGLE175°H/175°V wide viewing angle, the central view at any angle, the horizontal and vertical viewing angle can ensure the color, brightness uniform. Water & Dust ResistantCOB display is sealed by epoxy resin and has no bare pad, which protects the LEDs from water, dust, oil stain, collision, and static. High contract specialized Black Seal technology: Pristine black & color expression The fusion of an exceptionally black base with patented Optical painting material: Matte Black, Natural Black, Brilliant Black, deliver deep black levels for intense contrast and immaculate detail for a variety of applications. Pixel to pixel CalibrationFine-tune multi-step factory calibration process tunes video wall displays to the optimal uniform brightness and color across multiple displays to fit any broadcaster application or environ- meant. Inspection SystemHigh-precision optical recognition system marks the R/G/B coordinate file by judging the chip brightness and threshold on the speed of 40K/S(mini chip) , fully inspected to reach zero failure rate before delivery.
