What is the difference between LCD and led LCD? Compared with LCD, LCD has brightness, power consumption, visual angle and refresh rate, all have the advantage of canceling navigation to the web page. Using LED technology, a thinner, brighter and clearer display than LCD can be produced. 1. The power consumption ratio of LED to LCD is about 1: 10, and LED is more energy-saving. 2. LED has higher refresh rate and better performance in video. 3. LED provides a viewing angle up to 160 degrees wide, can display various text, numbers, color images and animation information, and can play color video signals such as TV, video, VCD, DVD, etc. 4. The single element reaction speed of the LED display screen is 1000 times that of the LCD screen. It can also be taken care of under strong light and adapt to the low temperature of minus 40 degrees. Simply put, LCD and LED are two different display technologies. LCD is a display screen composed of liquid crystals, while LED is a display screen composed of light emitting diodes. Dear friends, now we should understand the difference between LCD and led! Then everyone will say that LED is so good, then I must buy LED display! However, the focus of this article also comes: The LED display screen currently on the market is not a real LED display screen, accurately speaking, it is an LED backlight liquid crystal display, the LCD panel is still a traditional LCD screen. In a sense, it is somewhat fraudulent! South Korea's Samsung company was once convicted by the British Advertising Association of violating the country's advertising law because its 'LEDTV' LCD TV was suspected of misleading consumers. For liquid crystal displays, the most important key is their liquid crystal panel and backlight type, while the liquid crystal panel of displays on the market generally adopts TFT panel, which is the same, the only difference between LED and LCD is that their backlight types are different: LED backlight and CCFL backlight (That is, fluorescent lamps), Respectively, diode and cold cathode lamp tube.
