Give answer of my question​

Answer 1

Answer:

LCD

LCD stands for ‘liquid crystal display’. It means that the active part of the monitor is a layer of liquid held between two pieces of polarized glass. A light from behind the liquid shines through the glass and illuminates the crystals.

LED

LED stands for ‘light-emitting diode’. LEDs are used as a light source in home light bulbs, traffic lights, smartphone and laptop screens and, of course, monitors. LEDs producing infrared light have been in your remote controls for decades. The time display on your clock radio? Yup, those are LEDs as well. In monitors, LEDs are the backlight used to illuminate the liquid crystal display.
