What is LCD and its features?
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. Liquid crystals do not emit light directly, instead using a backlight or reflector to produce images in color or monochrome.
What do you mean by LCD explain?
liquid crystal display: a method of displaying readings continuously, as on digital watches, portable computers, and calculators, using a liquid crystal film, sealed between glass plates, that changes its optical properties when a voltage is applied.
What are the features of a screen?

What are the characteristics of LCD monitors LCD screen and CRT monitors?
[6] [7][8] LCD monitors have higher resolutions, higher small-spot contrast ratios, and superior gray scales compared with CRT monitors. 9 LCD monitors are also more reliable than CRT monitors because they use lower voltage and require less power consumption and maintenance. …
What is LCD display in Mobile?
A liquid crystal display is the most common display type among mobile phones because of its low power consumption and good image quality. They are generally easy to read, even under direct sunlight. The smallest element of an image displayed on a LCD is the pixel.
How does a LCD display work?
The Basics of LCD Displays They work by using liquid crystals to produce an image. The liquid crystals are embedded into the display screen, and there’s some form of backlight used to illuminate them. When the backlight is activated, it produces light that is somewhat obstructed by the liquid crystals.
What is LCD monitor?
Liquid Crystal Display (LCD) monitors feature a layer of liquid held between two pieces of polarized glass. The LCD monitor does not produce its own light. Instead, additional lighting behind the screen shines through the glass and illuminates the crystals. LCD monitors are usually backlit by fluorescent lamps.
What are the three features of monitor?
A monitor usually comprises a visual display, some circuitry, a casing, and a power supply. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) with LED backlighting having replaced cold-cathode fluorescent lamp (CCFL) backlighting.
