Nowadays, almost every family will have a very popular TV, and people will watch TV at home when they are free. However, when people watch TV, they only care about the plot and so on in TV, and people don't care about their TV. Among them, the TVs in your home are mainly LED TVs and LCD TVs. The following editor will briefly introduce the essence and characteristics of these two TVs.

LED TV refers to a TV that uses LED (Light Emitting Diode) as a display device, usually used for low-precision displays or large outdoor screens. At present, in the home appliance industry in mainland China, the strict name of the so-called LED LCD TV is "LED backlight LCD TV", which refers to LCD TV with LED as the backlight, and it is still a type of LCD. It uses LED light sources instead of traditional fluorescent tubes, with better pictures, longer theoretical lifespan, more environmentally friendly production process, and thinner LCD panels.

LCD TV is the full name of liquid crystal display: it includes TFT, UFB, TFD, STN and other types of liquid crystal displays. LCDs are constructed by placing liquid crystals between two parallel sheets of glass with many small vertical and horizontal wires in between. The rod-like crystal molecules are controlled to change direction by whether or not electricity is applied to refract light to produce an image.

Features of LED TV and LCD TV

LCD TVs display a lot of information (since the pixels can be made smaller), have a long lifespan (the device has almost no degradation issues, so it has a very long lifespan, but LCD backlights have a limited lifespan, but the backlight part can be replaced), and most importantly There is no electromagnetic radiation (safe for the human body and conducive to information confidentiality).

LED TV is environmentally friendly and energy-saving, and the LED backlight does not contain mercury, which meets the requirements of green environmental protection. LED TV backlight is also very power-saving. The internal driving voltage of LED is much lower than that of CCFL, and its power consumption and safety are better than CCFL. With wide color gamut and different luminous colors, LEDs can be divided into white LED backlight and RGB-LED backlight. The main advantage of white LED technology is lower power consumption, while the advantage of RGB-LED backlight is its excellent color expression.
