LED TV: LED TVs are actually LCD TVs (Liquid Crystal Display), which is a type of LCD TV. The main difference between LED TVs and traditional LCD TVs lies in the use of different backlight sources, which brings many differences in performance. LED TVs use light-emitting diodes as the backlight source, which has advantages over traditional LCD TVs in thickness, picture quality, lifespan, energy-saving, and environmental protection, and has become a recognized development direction for LCD TVs in the industry. Strictly speaking, LED TV refers to a TV that uses LED (light-emitting diode) as the display device, and is generally used for low-precision displays or outdoor large screens. It replaces the traditional fluorescent tube with the LED light source, the picture is better, the theoretical life is longer, the production process is more environmentally friendly, and it can make the liquid crystal display panel thinner. LCD TV: Liquid crystal TV, also known as LCD TV, is based on the principle that liquid crystals emit light under the action of voltage. There are three types of liquid crystals that make up the screen: red, green, and blue, which are called the three primary colors. They are arranged in a certain order. These liquid crystals can be stimulated by voltage to show different colors, and the combination of different proportions can show ever-changing color.
