What is the difference between lcd and led?

LCD (short for Liquid Crystal Display) liquid crystal display. The LCD is constructed by placing a liquid crystal cell in two parallel glass substrates, a TFT (thin film transistor) on the lower substrate glass, a color filter on the upper substrate glass, and liquid crystal molecules controlled by signal and voltage changes on the TFT. The direction of rotation is such that the polarization of each pixel is controlled to be emitted or not for display purposes.


LED is the abbreviation of Light Emitting Diode. LED applications can be divided into two categories: one is LED display; the other is LED single tube application, including backlight LED, infrared LED and so on. As far as LED displays are concerned, China's design and production technology levels are basically in line with international standards. The LED display is composed of LED arrays. It adopts low-voltage scanning drive, which has the characteristics of low power consumption, long service life, low cost, high brightness, less failure, large viewing angle and long visible distance.
