LED vs LCD

The difference between LED and LCD is that LED, which stands for Light Emitting Diode, uses diodes for the placement of light and provides a distinct and sharp picture, whereas LCD, which stands for Liquid Crystal Display, uses fluorescent lights for the placement of light.

LED can be categorized as a subset of LCD, which is in great demand nowadays for the manufacturing of electronic devices as it has a very long life, provides the best picture quality, and also has a high definition output.

LCD, which was in great use a few years back, has become outdated due to the invention of LED. LCD is basically a submissive device that uses fluorescent tubes to lighten the image.

Parameters of ComparisonLEDLCD
Picture QualityLED provides a much better picture quality due to the presence of RGB colour wheels.LCD is not able to provide as good picture quality as LED.
PriceLED’s are costlier than LCDs.LCD’s are cheap in comparison.
LifespanThe average lifespan of LED is close to 1,00,000 hours.The average lifespan of LCD is close to 75000 hours.
Power Efficiency LED’s are highly power effective and consume comparatively less power.LCDs are less power efficient and utilize more power.
Environment FriendlyLED does not pose any harm to the environment as no mercury is used for the production of LED.LCD is a great threat to nature as mercury is used in its manufacturing.

What is LED?

Light Emitting Diode (LED) is an indication of how technology has reached new heights in the modern world. It has displaced the fluorescent tubing with backlight technology which helps it deliver a precise and clear image.

LED is basically used in the manufacturing of computer monitors, Bulbs and Televisions. LED televisions are in great demand now due to the extraordinary features and benefits which they provide.

It works on the principle of Electroluminescence. Light in a LED is produced when particles carrying current, also known as electrons and holes, come collectively within the material of the semiconductor.

Gamers use LED screens for playing high graphic games as LED screens have a much better contrast in comparison to LCD screens.

What is LCD?

Liquid Crystal Display (LCD) is made of a material called Liquid Crystal which is a type of substance that is neither liquid nor solid but comes somewhere in the middle of these two.

There are, in general, three types of LCD TVs that are Flat screen LCDs, Front Projection LCDs, and Rear projection LCDs.

There are numerous disadvantages of LCD, like it has an unusual refresh frequency and it also suffers from action blur consequences.

The major elements that are necessary for displaying an image on the LCD screen are Light, colour and the method to regulate the light and colours on the screen.

Main Differences Between LED and LCD

  1. LEDs work on the well-known principle of Electroluminescence, whereas all LCDs function on the basic principle of blocking light energy.
  2. If we discuss the relevance of LED and LCD in the modern era, then LED are much more relevant and in use than LCD.
