What is the difference in power consumption between LED and LCD screens with the same size? Take 22.5 as an example.

First of all, it must be clear that LED is not a screen, but a backlight technology. Liquid crystal displays generally use TN panel, but ordinary liquid crystal displays use CCFL backlight technology, and LED displays generally use TN panel, but LED backlight. The difference of backlight technology leads to the difference of power consumption between them. As for the difference, it is still obvious.

The 22-inch display adopts ccfl backlight technology, which varies from 0 to 45 (generally not more than 50)W according to the brightness.

The maximum power consumption of LED backlight LCD with the same size is generally less than 25W. That is to say, in daily use,

The power consumption of the former is as high as 30~40W, while that of the latter is only 15~20W. The difference is twice. Once the former has electricity, one day,

The latter can be used for two days.
