LCD screen itself does not emit light and needs external light source to provide lighting. LCD uses fluorescent tube to provide lighting for LCD screen. Led uses semiconductor light-emitting tube to provide lighting for LCD screen. Led saves power and can be thinner than LCD. As LED is a new backlight technology, its cost is higher, so its price is also high. In fact, there is little difference between the two images, The image quality is determined by the LCD panel, and has nothing to do with the backlight.

LCD is liquid crystal display screen, which is the screen of LCD TV and liquid crystal display that you usually see. LED is a cold light-emitting diode, LED display is mainly used for large area display, such as the display screen on the building. For example, people's Square, Xujiahui, baxianqiao and other places, the huge display on the building is led display. The display of LED is similar to the three primary color display of CRT before. Each display module is composed of three primary color LED cold light emitting diodes, and then tens of thousands of modules form a huge display.There should be no need to answer the price difference between the two. It's a big difference. One is for commercial use.
