QLED vs. OLED vs. LED: Which Should You Buy?

If you are looking to buy a new TV or Audio, or if you happen to visit an electronics retailer, you will have seen different brands and models offering better technology. This is the TV manufacturers’ way of differentiating themselves from their competitors. But which technology should they buy?

The most common TVs today are LED, OLED and QLED TVs. Take a closer look at these TV technologies and differentiate between them. We will then help you find the best TV technology for your needs and requirements.

How LED, QLED and OLED TVs work?

A set of pixels is used to create an image and the brightness of the pixels is determined by what the computer needs to see. However, there are different ways of doing this, and each technology has its advantages and disadvantages.

So let’s look at the differences between how LED, QLED and OLED TVs work.

LED TVs

LED TVs work on the same principle as the first LCD TVs. It’s a flat screen with several layers to control light and colour. The bottom layer is usually the backlight, which illuminates the screen and allows the image to be viewed. LEDs are used instead of fluorescent tubes or other light sources, hence the name LED TV.

LED TVs consist of several layers, but the basic mechanism is as follows. The light source, the LED screen, is located in the innermost part of the TV. In front of the light source is a vertical polariser, which allows only vertical light waves to pass through.

QLED TVs

QLED televisions operate on the same principles as LED televisions: backlight, vertical polariser, liquid crystal layer, horizontal polariser, colour layer and screen. However, QLED televisions do not use white LED backlighting. This is because white LED backlights are usually not perfectly white. If you look at LED strips, you will see that they usually have a yellow tint.

To solve this problem, Samsung, the leading manufacturer of QLED TVs, uses a quantum dot layer as its light source. Instead of using white LEDs as backlights, the company uses an LED light source to excite the crystals in the quantum dot layer. In this way, the quantum dot layer emits a natural white light that is brighter than conventional LED light sources.

OLED TVs

The main difference between OLED televisions and LED and QLED televisions is the type of light emission: OLED TV do not need a backlight, the individual pixels themselves emit light.

In contrast, with an LED or QLED TV, the entire backlight needs constant power, and if part of the screen is black, the liquid crystal layer blocks the light from the backlight.

Differences between LED, QLED and OLED TVs

LED, QLED and OLED TVs have their own advantages and disadvantages, and no one TV technology is universally superior to another. Therefore, there are a number of factors to consider when choosing between these TVs.

Brightness

Unless the TV is set up in a pitch-dark room, brightness plays an important role in the viewing experience. The brightness should allow the screen to be seen clearly, even when the surroundings are bright. This is particularly important if the TV is installed in a living room with lots of windows.

This is where QLED TVs come into play. Thanks to the quantum dot layer, QLED TVs are much brighter than simple LED TVs. They are also highly energy efficient, so there is no need to spend more on electricity just to get a brighter picture.

Brightness is usually the weak point of OLED TVs. As each sub-pixel produces its own light, TV manufacturers cannot make them very bright.

Contrast ratio

OLED TVs are particularly high contrast because of the way they work: the backlight of LED and QLED TVs is always on, whereas the individual pixels of OLED TVs are only switched on when necessary. This means that OLED TVs have infinite contrast, reproducing the deepest blacks and richest colours.

One way of seeing this is by moving a small white object in front of a black image.  For example, a white mouse pointer over a dark desktop background. On most LED and QLED TVs, there is a slight brightening glow on the black background around the white mouse pointer.

This problem does not occur with OLED TVs: due to the way OLED screens work, the pixels around a small object remain black no matter how bright or white it is.

Colour accuracy

OLED TVs have always been ahead of other TV technologies due to the way they work. However, QLED TVs are catching up fast, especially since Samsung launched its Neo QLED TVs, which combine Mini LED technology with Quantum Dot Display technology.

However, if you are looking for the best colour accuracy, you should stick with OLED TVs. However, if you don’t want to use this technology because your living room is bright and airy, you should consider a QD OLED TV, where the OLED screen is covered with a layer of quantum dots.

Burn-in of the picture

Although OLED technology has been on the market for a long time and has made great progress, it still suffers from the problem of image burn-in, especially with prolonged use. You should therefore avoid OLED TVs if you want to watch the same channel every day or play games for hours on end.

Opt for a QLED or LED TV instead, as these technologies do not suffer from picture burn-in. However, if you already own an OLED TV, you should know the causes of OLED picture burn-in and how to fix and prevent it.

Price

This is often the most significant consideration when buying a TV. So, if you have a limited budget and want to get the biggest screen for you, you should stick with easy installment plans. That’s because this is the most affordable way to buy your desired product. Lahore Centre in this way will help you out. It is the only one best electronic store in Lahore that offers easy installment plans for the comfort of their customers.

Image burn-in

Although OLED technology is evolving rapidly, the picture can still burn in, especially with prolonged use. If you watch the same channels or play the same games for hours every day, avoid OLED TVs.

Instead, opt for a QLED or LED TV. With these technologies, the picture doesn’t burn. However, if you already own an OLED TV, you should be aware of the causes of OLED picture burn-in and how to remedy or avoid it.

LED, QLED and OLED: which TV to choose?

Now that you know the differences between the three TV technologies, you need to choose the best technology for your needs. Decide what’s most important to you: affordability, brightness or colour accuracy.

However, when buying a television, screen technology isn’t the only criterion to consider. There are many other factors to consider when choosing a television for your family.
