What LCD means?
A liquid-crystal display ( LCD ) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. LCD screens are also used on consumer electronics products such as DVD players, video game devices and clocks.

What are the advantages of LCD?
5 Advantages of Liquid-Crystal Displays (LCDs) #1) Energy Efficient. LCDs are known for their energy -efficient properties. #2) Long-Lasting. Another advantage of LCDs is their ability to last for a very long time. #3) LED Backlighting. LCDs support backlighting with light-emitting diode (LED). #4) No Screen Burn-In. #5) Supports Small and Low-Profile Sizes.
What is the working principle of LCD?
The LCD works on the principle of blocking light. While constructing the LCDs, a reflected mirror is arranged at the back. An electrode plane is made of indium-tin-oxide which is kept on top and a polarized glass with a polarizing film is also added on the bottom of the device.
What is the liquid in an LCD?
The basis of LCD technology is the liquid crystal, a substance made of complicated molecules. Like water, liquid crystals are solid at low temperatures. Also like water, they melt as you heat them.
Is LCD bad for eyes?
Mobile devices use LCD screens which emit blue light and thus negatively affects not only vision but also overall health. Continual extended screen time mainly can impact your eyes in two major ways. When we look at a screen, our blink rate drops significantly, thus causing digital eye strain.
Is LED TV bad for your eyes?
