What Is the Common Cathode LED Display Power Supply Technology_ What Are the Advantages
After years of development, the conventional Gongyang LED display has formed a stable industrial chain, which has driven the popularity of LED display. However, there are also some disadvantages such as too high screen temperature and too much power consumption. After the emergence of common cathode LED display power supply technology, it has attracted great attention in the LED display market. This power supply mode can save up to 75% energy. What is the power supply technology of common cathode LED display? What are the advantages of this technology?
1. What is a common cathode LED display?
"Common Yin" refers to the common Yin power supply mode, which is actually an energy-saving technology for LED display screen. It refers to the common Yin mode to supply power to LED display screen, that is, separate the R, G and B (red, green and blue) of LED beads to supply power, and accurately distribute current and voltage for R, G and B beads respectively, because R, G and B (red, green and blue) The best working voltage and current required by the lamp bead are different. In this way, the current first passes through the lamp bead and then to the IC negative electrode, the forward voltage drop will be reduced and the conduction internal resistance will be reduced.
2. What is the difference between common Yin / common Yang LED displays?
. different power supply modes:
The common cathode power supply mode is that the current first passes through the lamp bead and then to the IC negative electrode, so that the forward voltage drop becomes smaller and the conduction internal resistance becomes smaller.
The common positive current flows from the PCB board to the lamp beads to uniformly supply power to R, G and B (red, green and blue), which leads to the increase of the forward voltage drop of the circuit.
Common cathode, which will separately provide current and voltage to R, G and B (red, green and blue). The voltage requirements of red, green and blue light beads are different. The red light bead voltage is required to be about 2.8V and the blue-green light bead voltage is required to be about 3.8V. In this way, the power supply can achieve accurate power supply with less power consumption, and the heat generated by the LED display screen in operation is much lower.
In Gongyang, R, G and B (red, green and blue) are uniformly supplied with a voltage higher than 3.8V (such as 5V). At this time, the voltage obtained by red, green and blue is unified 5V, but the optimal working voltage required by red, green and blue beads is much lower than 5V. According to the power formula P = UI, under the condition 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 produce more heat during operation.
3. Why is the heat of common cathode LED display lower?
The special common cathode power supply mode of the cold screen makes the LED display screen produce less heat and low temperature rise. Under normal conditions, the temperature of the cold screen is about 20 lower than that of the conventional outdoor LED display of the same model in the white balance state and when playing video. For products with the same specifications, under the same brightness, the screen temperature of common cathode LED display screen is more than 20 degrees lower than that of conventional common anode LED display screen products, and the power consumption is more than 50% lower than that of conventional common anode LED display screen products.
High temperature and high power consumption of LED display screen have always been the key factors affecting the service life of LED display products, and "common cathode LED display screen" can solve these two problems.
4. What are the advantages of common cathode LED display?
. accurate power supply, true energy saving:
Gongyin products adopt accurate power supply control technology. Based on the different photoelectric characteristics of the three primary colors of LED, red, green and blue, it is matched with the display and control system of intelligent IC and independent private model to accurately distribute different voltages for LED and driving circuit, so that the power consumption of the products is about 40% less than that of similar products in the market!
. true energy saving brings true color:
The common cathode LED driving mode can accurately control the voltage, reduce the power consumption and reduce the calorific value. Under the continuous operation of LED, the wavelength does not drift and stably displays the real color!
. true energy saving brings long life:
The energy consumption is reduced, which greatly reduces the temperature rise of the system, effectively reduces the LED damage probability, improves the stability and reliability of the whole display system, and greatly prolongs the service life of the system.
5. What is the development trend of common cathode technology?
The LED, power supply, drive IC and other supporting technologies related to the common cathode LED display technology are not as mature as the LED industry chain of common Yang. In addition, the current series of common cathode IC is incomplete and the overall volume is not large, while common Yang still occupies 80% of the market.
At present, the slow promotion of common cathode technology is mainly due to the high production cost. Based on the cooperation relationship of the original supply chain, common cathode needs customized cooperation at all ends of the industrial chain such as chip, packaging and PCB, and the cost is high.
In this era of high voice for energy conservation, the emergence of common Yin transparent LED display has undoubtedly become the support point pursued by this industry. However, there is still a long way to go to realize the comprehensive promotion and application in a greater sense, which requires the joint efforts of the whole industry. As the development trend of energy saving, the common cathode LED display involves the use of electricity and operation cost. Therefore, energy saving is not only related to the interests of LED display operators, but also related to the use of national energy.
From the current situation, the common cathode LED energy-saving display screen will not increase too much cost than the conventional display screen, and will save cost in later use, which is highly praised by the market.

How to Ensure the Quality of LED Display and Prolong Its Service Life?
With the full spread of LED display in the market, many consumers often ignore the daily maintenance and repair of LED display. Such long-term use will not only affect the user's visual experience, but also greatly reduce the service life of the display. So, how to ensure the quality of LED display? It also depends on the daily maintenance of LED display
1 How to ensure the quality of LED display
Anti static LED display electronic display screen assembly factory shall have good anti-static measures. Special anti-static ground, anti-static floor, anti-static soldering iron, anti-static table pad, anti-static ring, anti-static clothing, humidity control, equipment grounding (especially foot cutting machine) are the basic requirements, and should be tested regularly with an electrostatic instrument.
1. Anti static LED display electronic display screen assembly factory shall have good anti-static measures. Special anti-static ground, anti-static floor, anti-static soldering iron, anti-static table pad, anti-static ring, anti-static clothing, humidity control, equipment grounding (especially foot cutting machine) are the basic requirements, and should be tested regularly with an electrostatic instrument.
2. Driving circuit design the driving circuit board on the LED display module and the layout of the driving IC will also affect the brightness of the LED. Because the driving IC output current is transmitted too far on the PCB, the voltage drop in the transmission path will be too large, affecting the normal working voltage of the LED and reducing its brightness. We often find that the LED brightness around the LED display module is lower than that in the middle, which is why. Therefore, to ensure the consistency of display brightness, it is necessary to design the distribution diagram of driving circuit.
3. The nominal current of the design current LED is 20mA. Generally, it is recommended that the maximum use current should not exceed 80% of the nominal value. Especially for the display screen with small point spacing, the current value should be reduced due to poor heat dissipation conditions. According to experience, due to the inconsistency of attenuation speed of red, green and blue LEDs, the current value of blue and green LEDs shall be reduced to maintain the consistency of white balance after long-term use of the display screen.
4. Mixed lamps LEDs with the same color and different brightness levels need to be mixed, or inserted according to the lamp inserting diagram designed according to the discrete law, so as to ensure the consistency of the brightness of each color on the whole screen. If there is a problem in this process, the local brightness of the display screen will be inconsistent, which will directly affect the display effect of the LED display screen.
5. Control the perpendicularity of the lamp. For the in-line led, there should be enough technology to ensure that the LED is perpendicular to the PCB when passing through the furnace. Any deviation will affect the brightness consistency of the set led, and color blocks with inconsistent brightness will appear.
6. The temperature and time of wave front welding shall be strictly controlled. It is recommended that the preheating temperature be 100 5 and the maximum temperature shall not exceed 120 , and the preheating temperature rise shall be stable. The welding temperature shall be 245 5 , and the welding time shall not exceed 3 seconds. Do not vibrate or impact the LED after passing the furnace until it returns to normal temperature. The temperature parameters of wave soldering machine shall be detected regularly, which is determined by the characteristics of LED. Overheating or fluctuating temperature will directly damage led or cause hidden dangers of LED quality, especially for small-size circular and Oval LEDs such as 3mm.
7. When the LED is not on, there is often more than 50% probability that it is caused by various types of false soldering, such as LED pin false soldering, IC pin false soldering, needle and bus bar false soldering, etc. The improvement of these problems needs to strictly improve the process and strengthen the quality inspection. The vibration test before leaving the factory is also a good inspection method.
8. Heat dissipation design led will generate heat when working. Too high temperature will affect the attenuation speed and stability of LED. Therefore, the heat dissipation design of PCB board and the ventilation and heat dissipation design of box will affect the performance of LED.
2 Aggregation of daily maintenance and repair methods of LED display screen
To avoid possible problems, we can choose passive protection and active protection. Passive protection means that users in some Internet cafes, dormitories and other public places can choose to buy displays with tempered glass, which can make your display "invulnerable to weapons and water and fire", but it will affect the color of the display and reflect light; Active protection is to be more careful in normal use, try to keep the items that may cause damage to the screen away from the screen, and wipe the screen gently as much as possible when cleaning the screen to minimize the possibility of damage.
02 Maintain the humidity of the environment
All users who once spilled drinks on the keyboard and caused keyboard damage know this common sense. Don't let anything with moisture enter your LED display. If fog is found, wipe it gently with a soft cloth before turning on the power. If the moisture has entered the interior of the display, the display must be placed in a warm and dry place in order to evaporate the moisture and organics. Powering on the liquid crystal display with humidity can lead to the corrosion of the liquid crystal electrode and permanent damage.
LCD has the closest relationship with our users, so it is very necessary to do a good job of cleaning and hygiene. In fact, the LCD is also particularly easy to get dirty. The white appearance is really good-looking, but if you don't pay attention to maintenance, it will soon turn yellowish; Piano baking paint is really good, but after a week of use, the shell must be full of fingerprints; Even if it is an ordinary black matte material, after a period of time, there must be a piece of dust on the screen. Many users know to clean the LED display regularly, but do you know how to clean the LCD correctly?
*Precautions
For most LED backlight displays, the most vulnerable place is the screen. Generally, the hardness of the screen is below 3H (the hardness of the pencil lead). If you don't pay attention to it during normal use, it is easy to be "accidentally injured" by other devices, and once the screen is damaged, it means that the LED display is basically scrapped.
Well, the above is how to ensure the quality of LED display screen and the content introduction of daily maintenance and repair of LED display screen. I hope it will be helpful to everyone more information and more content are presented on qianjia.com. Welcome to pay attention or click to check!
