Common Cathode micro COB LED Display

COB display, using chip-on-board technology, enables transistor chips to be mounted directly on LED beads, thus realizing higher pixel density and wider viewing angle. COB abandons the concept of bracket, no plating, no reflow soldering, no SMD, the process flow is reduced by 1/3. in the solid crystal, soldering process is comparable to the efficiency of SMD (e.g., Indoor HD LED Display), but in terms of dispensing, spectroscopy, sorting, and encapsulation, COB packaging is much more efficient. the optoelectronic performance of COB in terms of color consistency is better, the angle of view is large, the spot uniformity is good. Higher brightness, good color mixing, large viewing angle and high brightness. Common Cathode micro COB LED Display is an improved technical solution based on Common anode structure (refer to Product Common anode micro COB LED Display) to realize energy saving of LED display. It refers to the use of the common cathode method to drive the LED display, where the c…
