How LCDs Work - HowStuffWorks
LCDs are common because they offer some real advantages over other display technologies. They are thinner and lighter and draw much less power than cathode ray tubes (CRTs), for example. But just what are these things called liquid crystals?
How do LCDs (liquid crystal displays) work? - Explain that Stuff
3 天之前 · Like laptop computers, most 21st-century televisions have flat screens with LCDs (liquid-crystal displays) —the same technology we've been using for almost half a century in things like calculators, cellphones, and digital watches. What are they and how do they work? Let's take a closer look!
Liquid-crystal display - Wikipedia
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 to display information. Liquid crystals do not emit light directly [1] but instead use a backlight or reflector to produce images in color or monochrome. [2]

How do liquid crystal displays (LCDs) work? - PhysLink.com
In liquid crystal displays (LCDs), use is made of linear polarisers, familiar to most as the glass in polarising sunglasses. If you 'cross' two polarisers (i.e. arrange them at 90 degrees to each other) then light does not pass through. This is the basis of the LCD, but between the cross polars the liquid crystals are arranged with a 'twist'.
