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]
A liquid-crystal-display television (LCD TV) is a television set that uses a liquid-crystal display to produce images. It is by far the most widely produced and sold type of television display.
LCD is a flat panel display technology commonly used in TVs and computer monitors. It is also used in screens for mobile devices, such as laptops, tablets, and smartphones. LCD displays don’t just look different from bulky CRT (Cathode Ray Tube) monitors, the way they operate is significantly different as well.
Liquid crystal displays are super-thin technology display screens that are generally used in laptop computer screens, TVs, cell phones, and portable video games. LCD’s technologies allow displays to be much thinner when compared to a cathode ray tube (CRT) technology.
LCDs are prevalent in televisions, computer monitors, and smartphones, offering advantages such as energy efficiency and slim profiles. This article explores the definition, operation principles, key components, advantages, limitations, and applications of LCD technology.
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? The name "liquid crystal" sounds like a contradiction.
LCD displays work by using individual pixels to display visuals, moving or stationary. Each pixel will display a color mixed by the RGB color filter with each color’s filter associated with one of the pixel’s sub-pixels. The sub-pixels are where the degree of light is determined, thus affecting the degree of prominence of its respective color.
