Difference Between LED and LCD

By Aina Parasher|Updated : May 2nd, 2022

Difference Between LED and LCD: LCD and LED are vital to grasp since they are quite similar and it is easy to confuse one with the other. The acronym LCD stands for liquid crystal display, whereas LED stands for light-emitting diodes. LCDs and lights vary in that LCDs typically employ fluorescent lights whereas lights use light-emitting diodes.

The construction of LCD and LED panels is nearly identical, as is the technology that powers them. The different types of televisions feature two layers of polarized glass, through which the liquid crystals are blocked as well as passed the light. As a result, one of the most significant similarities and difference between LCD and LED is this.

What is LED?

LED is a form of LCD that has grown in popularity as technology has progressed. Backlight technology replaces the fluorescent bulb, resulting in a crisper image than the LCD. The viewing angle of LEDs is greater than that of LCDs. In comparison to LCD displays, it has a greater black level and contrast. In comparison to LCD, LED provides higher color fidelity.

LED is a subset of LCD, which is in high demand currently for electronic device manufacturers because of its long life, excellent picture quality, and high definition output. One of the most essential characteristics of LED is that it is energy efficient, which means it uses less energy.

What is LCD?

LCD stands for liquid crystal display, and it is a passive device that employs fluorescent bulbs to brighten the image. One of the most distinguishing features of LCD is that it is lighter than LED and can display a wide range of colors.

An LCD is a passive device, meaning it does not emit any light in order to show characters, animations, films, and other content. LCDs employ fluorescent tubes to illuminate the picture, but they can't give the clarity that LEDs can. It has high color accuracy, however when we compare LED and LCD color accuracy, we can see the difference. When viewing an image on an LCD, the wide angle reduces by 30 degrees from the picture's center, and the contrast ratio falls by the same amount.

FAQs

  • The basic difference between LED and LCD is that LCDs are often bulkier and less energy efficient whereas, LEDs are significantly slimmer and consume far less energy.

  • LCD stands for liquid crystal display. Texts and pictures in the form of dot matrix or segments are shown on LCDs. The LCD has a liquid crystal filament which is filled between the transparent electrodes.

  • LED stands for light-emitting diode. The LED is a PN junction diode that emits light when an electric current flows through it in the forward direction. It is constructed by doping the p-type and n-type material.

  • The picture quality difference between LED and LCD is that LEDs feature RGB color wheels, which generate crisper and more realistic images, they have greater picture quality. Furthermore, light-emitting diodes have a dimming feature that enables them to show realistic colors by filtering surplus light.

  • In terms of lifespan, the difference between LED and LCD is that LEDs have a lifetime of around 100,000 hours on average whereas, LCDs have a lifetime of around 75000 hours on average.

  • Based on power consumption, the difference between LED and LCD is that the LEDs are highly energy-efficient and use a small amount of power. On the other hand, LCDs are inefficient and waste a lot of energy.
