What do you know about LED TV?

Watching TV after dinner is our best pastime. If a home does not have a TV, it means that it has no "soul". However, with the development of technology, there are more and more types and models of TV. What are LCD , LED , OLED , 4K , 8K TVs? Next, the editor will share with you the key points of sharing LED TV and LCD LCD TV.

LED LCD TV and LED TV TV:

LED LCD TV is an epoch-making product after cathode ray tube TV. Early LCD TVs had high prices, low color saturation, and relatively short LCD life, but now these shortcomings have been overcome.

LED LCD TVs have the advantages of low power consumption, light weight, fashion, clear pictures, high contrast, and good dynamic performance, all of which are superior to cathode ray tube TVs.

In the early 1970s , the first liquid crystal display device was manufactured in Sharp, Japan. Liquid crystal is a substance between solid and liquid. In LCD TVs, a voltage is added to the liquid crystal between the two glasses, and images are reproduced through changes in molecular alignment and twists and turns. The screen generates images through the collision of electron groups, and forms images through the perspective reflection of the backlight.

According to the different backlight sources, it can be divided into LCD (fluorescent tube ) and LED (LED light string ) backlight sources, which are called LCD TV and LED TV respectively . In fact, they are all LCD panels and LCD TVs. LED backlight has lower power consumption, thinner size, better color and higher price. Most TV backlights these days are LED because they can be made super thin and more attractive, but they're all LCD TVs.
