The power consumption per square meter of the current LED electronic display is much smaller than before, mainly from the innovation of power supply, driver chip, and lamp beads, and with the fierce competition in the price of LED display, raw materials are also constantly shrinking, LED electronic display The passive power consumption of the screen is also much smaller. Today's electronic products are becoming simpler and more integrated. To accurately calculate the actual power of LED electronic displays, it is necessary to comprehensively calculate from the use environment, product model, scanning frequency, LED lamp bead manufacturer, driving current, and power supply distance. The use environment is the main factor for the power of LED electronic displays. Because the indoor display screen does not need too high brightness, it is enough to use 2121 lamp beads. The brightness of outdoor electronic large screens is greater than the illuminance, so large chip lamp beads such as 3535 or 2727 are needed to meet the brightness requirements. The product model can also affect the power consumption of LED electronic displays. For example, the comparison between outdoor P10 and outdoor P3, the number of lamp beads per square meter of P10 is 10,000, while the number of lamp beads per square meter of outdoor P3 LED electronic screen is 111,111. Calculate the P3 lamp from the density The number of beads is 10 times that of P10, so the conclusion is that the more beads in the LED electronic large screen, the greater the power consumption.
Lamp bead manufacturers have a slight impact on the power consumption of LED electronic displays, mainly because the current of each lamp bead is different, so the power will be different. The driver chip is similar to the lamp bead, and the current of each chip has its own voltage and current parameters. The power supply distance will have a little difference in the power of the LED electronic display. Everyone knows that if the distance is long, the conduction of the cable will be resisted. In addition, the cable will heat up after a long working time, so the longer the cable, the more current it will lose.
