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 current and voltage are precisely distributed to the R, G and B chips. The current first passes through the lamp bead and then reaches the cathode of the IC, which reduces the forward voltage drop and on-resistance, resulting in the desired energy saving effect of reduced screen heat, lower power consumption, and efficient response.

Product Advantage

Energy saving: COB LED display video wall with Common Cathode technology adopts precise electronic control, according to the different optoelectronic characteristics of the three primary colors of LED (red, green and blue), combined with the control system of Common Cathode IC, different voltages are precisely distributed to the LED driving circuit. This makes the product's power consumption more energy-saving and power-efficient compared to similar products (e.g. Indoor Led Display).

More stable true color: The common cathode driving method can precisely control the voltage, which not only reduces power consumption, but also reduces heat generation. In the case of continuous operation, there will be no wavelength drift, ensuring stable display of true color.

Extended screen life: After the energy consumption is reduced, the temperature rise of the system is significantly reduced, which effectively reduces the probability of LED damage, improves the stability and reliability of the whole display system, and more effectively extends the service life of the system.
