LED TV is completely used for LED imaging devices. In the strict sense, LED TV refers to a TV that uses LED (Light Emitting Diode) as a developing device. At present, the strict name of LED TV commonly referred to in the home appliance industry in mainland China is “LED backlight LCD TVâ€. LCD TVs that use LEDs as a backlight are still a type of LCD. It replaces the traditional fluorescent tube with LED light source, the picture is better, the theoretical life is longer, the production process is more environmentally friendly, and the liquid crystal display panel can be made thinner. The current LED TV only uses LED backlight or LCD LED TV is actually a liquid crystal display (LCD), which is a kind of LCD TV. It is different from traditional LCD TVs in that it uses different backlights, which brings many different performances. LED TVs use LEDs as LEDs. The backlight is more advantageous than the conventional LCD TV with CCFL backlight in terms of thickness, picture quality, life, energy saving and environmental protection. LCD display screen For the purpose of improving the quality of LCD TVs, TV manufacturers have begun to use LEDs as backlights for LCD TVs. Compared to traditional LCD TVs that use fluorescent tubes as backlights, LED LCD TVs display more realistic colors. In addition to the increase in color saturation, the dynamic adjustment of the picture allows the brightness and contrast to be dynamically corrected when displaying different pictures for better picture quality. LCD and LED difference and connection So, what is the relationship between LED and LCD? As mentioned above, LED is a light-emitting diode, just a component that provides a light source. LCD is called a liquid crystal display in English. In general, LED is a new technology TV that replaces LCD. In fact, LED is still white, but only backlight. Differently, traditional TVs use fluorescent tubes for screen brightness. LED backlight, red, green and blue In fact, the LED is a large luminous bead, but on the TV is a very flat plane. In the reality of the outdoor large screen, the LEDs display each color spot for display. The LED TV is made of very small LEDs. At the rear of the screen is a guarantee of brightness provided by one of its tiny LEDs. . Most of the screens you can see on the TV screen are red, green, and blue light spots that combine to present the image. Each of the LEDs behind will generate a lot of heat, causing the screen of the LED TV to be hot, but the LED TV can change this phenomenon. LCD TV using LED display technology At present, the wide range of LEDs used in the market is becoming wider and wider, and LED products that we are able to reach are also becoming more and more. Such as LED large screen, LED TV. They are all called LED products. I believe that many consumers have had such experience in the store. When the LED TV service staff introduces the LED TV to the user, most of them will give "LED is more advanced and advanced than LCD. It is an alternative to LCD. "Technology" such a description, but it must be clear that all home LED TVs in the market are actually one type of LCD TV, but the backlight is different. This statement is suspected of stealing the concept. In summary, it can be seen that the TV screen equipped with the LED backlight has better quality, longer theoretical life, more environmentally friendly manufacturing process, and can make the liquid crystal display panel thinner. However, it is recommended that consumers should make an expectation according to their own needs when purchasing flat-panel TVs, and then carefully observe the market conditions and repeatedly select them to ensure that they can buy back the goods they need at the highest possible cost.
