LCD (Liquid Crystal Display)

April 08 15:48 2017

LCD screens, usually found on the rear of digital cameras, allow you to preview and review photographs you are about to take or have taken. LCDs utilize two sheets of polarizing material with a liquid crystal solution between them. An electric current passed through the liquid causes the crystals to align so light cannot pass through them. Each crystal, therefore, is like a shutter, either allowing light to pass through or blocking the light and producing an image in color or monochrome.
