2. liquid-crystal display (LCD)
 A liquid-crystal display (LCD) is a flat panel display or other electronically
modulated optical device that uses the light-modulating properties of liquid
crystal combined with polarizers.
 LCDs are available to display arbitrary images (as in a general-purpose
computer display) or fixed images with low information content, which can be
displayed or hidden

3. Types of LCD
 Direct address display
 Passive matrix display
 Active matrix display

4. Advantages LCD
 1) Energy Efficient
LCDs are known for their energy-efficient properties. They still require power to
illuminate their respective pixels, but LCDs consume less power than non-LCD
devices.
 2) Long-Lasting
Another advantage of LCDs is their ability to last for a very long time. LCDs typically
don’t last forever, but they have a longer lifespan than that of other display devices.

5. Advantages LCD
 LED Backlighting
LCDs support backlighting with light-emitting diode (LED). LED, in fact, is the most
common type of backlighting used in their construction.
 No Screen Burn-In
You don’t have to worry about screen burn-in with LCDs. Screen burn-in is a
phenomenon that only occurs in display devices with phosphor-based pixels.

6. Disadvantages of LCD
 Slightly more expensive than CRT
 Can't act as a portal to another dimension
 Suffer from a motion blur effect
 High refresh rate
 Like the backlight ages, it can change colors slightly
 The aspect ratio and resolution are fixed
 Not proficient at producing black or very dark grays colors

7. Liquid crystal
 A liquid crystal is a state of matter between liquid and solid (a "mesophase"). They
change shape like a fluid but have the molecular alignment characteristics of a
solid crystal.
 Liquid crystals are composed of organic, rod-shaped molecules that align in
parallel, and the common types used in electronic displays are nematic,
cholesteric and smectic.

8. How its work?
 iquid-crystal display (LCD) is a popular type of technology used in electronic
displays. As the name suggests, it’s characterized by the use of liquid-filled
crystals to produce images.
 Because liquid crystals have light-modulating properties, LCDs are particularly
effective for this purpose. The liquid crystals don’t necessarily produce the light
used to create the images
