Liquid crystal displays (LCDs) use liquid crystals combined with polarizers to modulate light transmission and produce images. There are different types of LCDs including direct address, passive matrix, and active matrix displays. LCDs have advantages such as being energy efficient, long-lasting, and supporting LED backlighting without screen burn-in issues. However, LCDs can have slight motion blur, color shifts over time, and difficulty producing deep blacks. LCDs work by using the light-modulating properties of liquid crystals that are composed of rod-shaped organic molecules that align parallel to one another.

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
