What Is LED?

Technology is advancing faster than we can ever imagine, and even though there are some developments that are not the best for our future, some developments in the technological world help us to get a more quality lifestyle out of the products we own.


One of the biggest advancements in the technological world that help us get better views on our screens and use light bulbs or other technological devices more efficiently is LED. We will talk about LED technology and what LED is.

What is LED?

What is LED

Light-emitting diode, also known as LED, is a device created to emit light when an electric current passes through the semiconductor device.

When electrons and holes get together within this semiconductor device, it produces the light we know of in the screens of mobile phones, televisions, monitors, lamps, and many other devices that provides light or serve a purpose with the lights embedded in them.

Because the light is within the semiconductor device, LEDs are solid-state devices that create the differentiation between other light sources like heated filaments or gas discharge lights.

It is more technologically sound and provides a sturdier experience thanks to the semiconductor device that you build the LED in.

There are a variety of sizes available for LED TVs, with the most popular being 32 inches, and 40 inches.

However, there are also smaller sizes like 24 inches and 28 inches, as well as larger ones like 60 inches and up.

How Does LED Work?

LEDs are highly technological devices that need some background information to understand how they work.

However, in simplest terms, LEDs are simple, tiny light bulbs that easily fit into an electrical circuit and work together.

However, the biggest difference LED has from the older bulbs is that they do not have filaments burning out, and they are more electric use friendly as they use less electricity.

They work only by the electrons moving in a semiconductor device that the LED bulbs are in.

They last thousands of hours and these advantages make LEDs more popular and sturdier in the electronic device world.

LED Colors

LED Colors

LEDs also have different colors, and these colors depend on the wavelength they are able to emit.

So, the photon energy the LEDs have determines the wavelength of the light they will emit, which creates different colors in the LED bulb.

The variety of colors increased only recently as in the 90s; there weren’t as many color options as we have today.

If you are looking to use colored LED lights for a project or for something else, you can expect to have a variety of colors.

These colors are made with different wavelengths that LEDs can absorb with their photon energy.


There is actually not much of a difference between the two. In fact, LED is a type of LCD tv.

An LED tv is more advanced and comes with an additional layer that enhances the picture clarity of a tv.

All LED TVs have an LCD panel, and the difference in both lies in the type of lighting they use. LED screens use diodes, while LCD screens use fluorescent lights.

Because of the diodes, LEDs offers sharper pictures and thinner screen as compared to LCDs.

What is The Difference Between Full Array, Direct Lit & Edge Lit LED Tv?

In an LED tv, their are basically three types of “local dimming” techniques that dim the black areas behind an image in the tv to make them appear darker.

A full array LED screen covers the whole back of the screen with LEDs and provides better contrast and details in shadows as compared to others.

In this type of LED TVs, the LED is away from the screen, and this allows more light to spread to the pixels. Due to this reason, Direct-Lit LED TVs are more economical but thick.

Edge-lit LED screens light from the side to the back of the screen because of which these types of LED Tvs are thinner. In this type. some screens also allow effective dimming.

Which LED TV Should You Buy? Sony, Samsung or LG?

Which LED TV Should You Buy

Sony, Samsung or LG are all great brands to buy your LED Tv from, and the buying decision is based on what your personal choice and preference is like.

If you want great audio and video processing, then Sony should be your choice.

You can also enjoy the benefits of full app selection and built-in features like Google Assistant and Chromecast in it.

Having said that, Sony LED tv can be more expensive than its competitors, so keep an eye on that.

Samsung LED TVs, on the other hand, are appreciated for their QLED technology, which presents a wide range of colors and presents real-looking pictures.

Other features that you can find in a Samsung LED tv include deep smart-home integration and a smart tv platform. In terms of price and features offered, Samsung LED TVs are the best choice. However, note that they do not support Dolby Vision in favor of HDR10+.

LG LED TVs boast Amazon voice assistants and built-in google features. You may even find advanced connectivity in some premium versions of LG LED TVs.

The only downfall of most LG LED TVs is that they use nano cell LCDs which do not offer uniform brightness or good HDR performance.

The Verdict

To conclude, LEDs are the most technologically advanced bulb technology to create better images for our screens and help to use bulbs, remote control, and other technological devices with less electricity and for longer times.

LEDs are actually small light bulbs put within a semiconductor device.

This device helps to get the electrons and the holes together to produce a more quality light than older lights like heated filaments that burn out eventually.

You can also get different colors of LED lights for different purposes, which changes depending on the wavelength they are getting.

What is the right way to clean an LED tv?

Before cleaning your LED tv, make sure you turn it off and allow it to cool down.

Now you can simply use a soft microfiber cloth to clean the screen of the tv. Do not use chemicals, water, etc., on the screen to avoid damage.

Is it safe to lay an LED tv flat?

We understand that transporting a tv from one place to another may be challenging, but you should avoid laying your LED tv flat on any surface for more than a few minutes.

This is because when an LED tv is laid on its back, you keep it in a position with no support to its middle part. This distributes the weight of the tv unevenly, causing great damage.

Which LED Tv is better RGB or white?

Red, green & blue (RGB) LED tv offers richer color, whereas white LED tv costs less but offers less color gamut. So it is up to you which one you want to buy.
