Led background screen is the light source of the display (or LED backlight board)
Led background screen is the light source of the display (or LED backlight board)LED screen is a display device(personal opinion).
I don't know what you mean by your question.

What is the difference between LED background screen and LED screen

My Understanding: there is a big difference between the two, and the concepts of "TFT" and "led" are completely different.
I don't know what you mean by your questionTFT (thin film transistor) "thin film field effect transistor"LED (light emitting diode) "led"TFT (thin film transistor) is an application technology of LCD display.
the principle is that each liquid crystal pixel is controlled by a thin film transistor, and the matrix addressing control of the liquid crystal light valve solves the coordination of the light valve and the controller of the liquid crystal display, so as to achieve fast, high brightness and high contrastLED (light emitting diode) "light emitting diode" is one of the mainstream lighting products in the future. At present, one of the most widely used uses is to make large display screen, which is also called "LED electronic display screen", such as the electronic large screen of gymnasium.
LED (light emitting diode) "light emitting diode" is one of the mainstream lighting products in the futureAnother use of LED is as backlight.
nowadays, many displays begin to use LED as backlight.
LED is widely used as backlightIt's hard to say what the relationship between "led" and "TFT" is.
that is "TFT LCD with LED backlight."
commonly known as "LED technology display" or "LED display" (now many notebook manufacturers use LED technology to advocate the advantages of display.
in fact, it's not complete. Now we can only use white LED as backlight, but not RGB color as backlight). the advantages of LED backlight are more energy-saving and higher brightness. LED can realize natural light through RGB color matching (which has not been realized yet), but CCFL cannot.
another LED is a green light source.
it is an environmental protection light source advocated.
LED is a green light sourceI hope it can help you.
