LED display is a kind of energy saving and environmental protection product. The power of single square is relatively low. The market usage rate of LED display is higher and higher.How can LED displays save power?

LED display as a new type of display technology is a high brightness, is famous for its high energy saving, it is through the internal of small leds to show, so compared with other display products, it is the province electricity, but is only relative, if your screen is a large area, and color, it is a square of power consumption is 300-600 - w.Displays using different technologies vary widely in power consumption.Common displays include CRT, LCD and LED displays.These three displays have the largest power consumption with CRT, followed by LCD and LED.Take the common ordinary LED display (for example, the liquid crystal display with LED lighting in backlight), the general power consumption is about 25W.

If it is a monochrome LED display, the power consumption per square meter is about 150-200w, which is also related to the way you display.The maximum power consumption of the outdoor LED display (full-color) is about 800W/ m2, which means that when the outdoor LED display reaches its maximum power (peak) every moment, it will consume 0.8 degree of power per square hour.

Calculation of LED display power consumption: calculate the maximum power consumption according to the number of points.As an important part of the power supply system, the LED display power supply selects a qualified and reliable power supply, which has obvious improvement effect on the energy-saving effect and service life of the LED display.

If the LED display body area is relatively large, energy saving design can be adopted.There are two main ways to save energy on LED display:

1. When installing the screen body, install a multi-function card with a light sensor, so that the LED display can automatically adjust the brightness of the screen body according to the outdoor light intensity to achieve energy-saving effect.

2. The energy-saving IC and low-voltage power supply are adopted in the screen design. According to formula P=UI, the LED screen of the screen is driven by constant current, that is, the current is constant, the voltage is reduced and the power is reduced.

Learn the above two steps, easy to solve LED display power saving problem!
