Co-Yang VS Co-Yin Technical Explanation

The smallest unit of the LED display is the light emitting diode. Light emitting diodes are distinguished between positive and negative, positive conduction and reverse cut-off. Common cathode is the negative side of the light-emitting diode connected together, common anode is the positive side of the light-emitting diode connected together. The main difference between common cathode and common anode lies in two points.

The first point is energy saving. Red, green and blue light-emitting diodes do not all work at the same voltage, red light-emitting diodes work at a lower voltage than green and blue light-emitting diodes. The common cathode circuit red, green and blue light-emitting diodes are powered separately, allowing precise control of the distribution voltage. While the common anode circuit red, green and blue light-emitting diodes are unified power supply, can not precisely control the voltage, often unified input a larger voltage, resulting in power loss. The second point is low energy. The common cathode circuit precisely distributes the voltage, which effectively reduces power consumption and also reduces the heat generated by the screen.

Conventional common sun LED display after years of development, has formed a stable industry chain, driving the popularity of LED display, however, there are also the shortcomings of excessive screen body temperature and power consumption. After the emergence of the common yin LES suban video power supply technology, it has caused a high degree of concern in the LED display market. Because this power supply method can achieve up to 75% energy saving, so what is common yin technology? What is common negative technology?

What is a co-anode LED?

Co-anode LEDs consist of a number of individual LEDs, each individual LED consisting of a positive (anode) and a negative (cathode). In a co-anode LED, the anodes of all the individual LEDs are connected together, while the cathodes are independent so that an anode common is formed.

What is a common cathode LED?

Common cathode, referring to the common cathode power supply method, is in fact an LED display energy-saving technology, referring to the use of common cathode to power the LED display. That is, the use of the LED lamp beads R, G, B separate to power, precisely respectively for R, G, B lamp beads to allocate current voltage, because R, G, B lamp beads need the best working voltage and current is not the same, so that the current will first go through the positive voltage drop will be reduced and the on-state resistance will become smaller.

What is the difference between co-positive/co-generic LED displays?

Different power supply methods

Common positive is the current flowing from the PCB board to the lamp beads, supplying power to R, G and B uniformly, which leads to a larger forward voltage drop in the circuit.

The common cathode power supply method, by the current first through the lamp beads, and then to the IC negative, so that the forward voltage drop becomes smaller, the on-state internal resistance also becomes smaller.

Different supply voltage

Common Yang, is to R, G, B give a voltage higher than 3.8V unified power supply, at this time, red, green, blue get the voltage are unified, but red, green, blue these three lamp beads need the best working voltage is much lower than the unified voltage. According to the power formula P = UI, in the case of constant current, the higher the voltage, the higher the power, that is, the greater the power consumption. At the same time, the LED display will also generate more heat in its operation.

And common negative, it will separately provide current voltage to R, G and B respectively. Red, green, blue three kinds of lamp beads on the voltage requirements are different, red lamp beads voltage requirements in about 2.8V, blue and green lamp beads voltage requirements in about 3.8V, so that the power supply can achieve accurate power supply and lighting loss less, LED display in the work of the heat generated by much lower.

What LED displays in Enbon are common shade LED displays?

A low-energy outdoor product, the FC Pro has excellent performance with a waterproof IP67 rating, high screen refresh rate, high resolution and contrast ratio, vibrant colours and comfortable visual viewing, and offers a customised option for naked eye 3D.

What are the advantages of the above displays in common?

Precise power supply for real energy saving

Common Yin's LED display products use precise power supply control technology, based on the different photoelectric characteristics of LED red, green and blue, with only IC's display control system and independent private mode, for LED and drive circuit precision distribution of different voltages, so that the product power consumption compared to similar products on the market is more power-saving.

True energy saving brings true colour

Common negative LED display drive mode, can accurately control the voltage, reduce power consumption at the same time, reduce the heat, LED continuous work under the wavelength of no drift, stable display of real colour!

True energy saving with long life

The reduction of energy consumption, thus significantly reducing the temperature rise of the system, effectively reducing the probability of LED damage, improves the stability and reliability of the entire display system, greatly extending the life of the system.
