Common Cathode COB LED Screen
Flip-chip COB is the process of die-bond the chip directly onto the PCB board, without wire bonding, a simplified process contributes to less defect creation factor. bringing to high black occupancy and reliability.
Common Cathode It is an energy-saving power supply technology for LED displays where the current first passes through the LED chips and then reaches the negative pole of the driving IC, hence the name “common cathode

COB LED Wall Mass Transfer Technology
Visionpi’s patented mass transfer technique is a novel approach for transferring millions of micro LED chips accurately. With the mass transfer technology, the UPH of micro & mini LED displays is more than 2.5KK, and the mass production yield rate is more than 99.999%.
16-18 bit Color
Super Viewing Angle
175°H/175°V wide viewing angle undistorted color can be appreciated even from the side angles, captivating various pedestrians even if it is installed in a large public places.
Energy-saving
COB LED Screen
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 centers, conferences, TV, subway, large scale events, education, medical diagnosis, advertising, etc. applications.
High contrast
Specialized Black Seal technology: Pristine black & color expression The fusion of an exceptionally black base with patented Optical painting material: Matte Black, Natural Black, and Brilliant Black, deliver deep black levels for intense contrast and immaculate detail for a variety of applications.
Pixel to pixel Calibration
Fine-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- ment.
Inspection System
High-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.
