The 2.4 inch tft lcd manufacturer tells you that the electric power of the active matrix LCD display is smaller than that of a CRT. In fact, it has become the standard display screen for portable devices ranging from PDAs to notebook computers. But LCD technology is still too inefficient: even if you make the screen white, less than 10% of the light emitted from the background light source passes through the screen, and the rest is absorbed. Therefore, the power consumption of the new plasma display screen is already lower than that of the LCD screen with the same area.

1. The power consumption of monitors using different technologies varies greatly. Common monitors are CRT, LCD and LED monitors. Among these three displays, CRT consumes the most power, followed by LCD, and LED is the smallest;
2. The manufacturer of 2.4 inch tft lcd tells you that taking common ordinary LED displays, that is, liquid crystal displays with LED backlight as an example, the general power consumption is about 25W;
3. Taking this as an example, 25W multiplied by 24 hours per kilowatt-hour is equal to 0.6 degrees. That is, if it is displayed continuously 24 hours a day, the power consumption for one day is about 0.6 degrees;
4. The manufacturer of 2.4 inch tft lcd tells you that if it is a display with CCFL backlight, the power of a 22-inch LCD display is generally about 45W, and the power consumption of a day is 45W multiplied by 24 hours.
