At present, it is recommended to use LED backlight LCD TV for home use. LED TV uses LED color lights arranged in one plane to realize one pixel by controlling the brightness and degree of LEDs at different positions on the screen. Like the principle of LED advertising TV in square and other places, it is composed of many dense small lights. The feature of LED TV is that each point is a light, and it emits its own light, The advantage is high brightness, can be very bright: LED backlight LCD TV principle is like our common light box, first inside the white led directly illuminate the whole screen, and then cover the light box cloth in front, different from the light box is the light in front of the light box/
At present, it is recommended to use LED backlight LCD TV for home use.

The feature of LED TV is that each point is a light, and it emits its own light, The advantage is that the brightness is very high, and it can be very bright: the principle of LED backlight LCD TV is just like our common light box. First, the white LED inside directly lights up the whole screen, and then the light box cloth is covered on the front. Different from the light box, the light box cloth in front of the light box is printed. To change the image, the light box cloth needs to be replaced. The LED backlight TV uses liquid crystal to replace the light box cloth, LCD screens can control what light they let through through by electrical signals. In fact, it's LCD TVs. However, the backlight of early LCD TVs used fluorescent tubes. Now many manufacturers have changed the backlight fluorescent lamps into LED lamps. The advantages are mature technology, stable quality and affordable price. The disadvantages are that they first emit light and then display through occlusion, In brightness and contrast is not as good as LED color TV.. LED backlight and LED are the same problem, there is no comparison. LED backlight refers to the LED used as backlight, the main object is for the display screen, and LED is a light-emitting diode, currently mainly used as backlight or landscape lighting or commercial lighting occasions..
