What You Should Know About a QLED TV


If you are in the market for a new TV, consider investing in a QLED TV. These TVs use Quantum dot technology to produce a higher-quality picture while at the same time having a longer lifespan. If you’re interested in purchasing a QLED TV, read on to learn more about the technology. After reading this article, you should be well-equipped to make a decision. If you’re already familiar with LEDs, you can read about how QLED technology works.

Quantum dot technology

The process behind QLED TVs uses a layer of quantum dots over the backlight of the television. These tiny phosphorescent crystals emit light efficiently when exposed to light and can be tuned to produce specific colors. This process enables a television to show a full spectrum of colors. However, there is a downside. In the short term, the technology is still in its infancy. But with some further development, it might soon become the most popular television.

The process of incorporating quantum dots into a TV’s design is still in its early stages, but it could lead to lower cost and closer performance to an OLED television. Samsung, for one, is leading the charge to combine quantum dots with OLED. It is known as QD-OLED for short. This technology is a hybrid of the two technologies and has several benefits over current QLED and OLED televisions.

Quantum dots are tiny particles that range from two to 10 nanometers in diameter. Their size determines which color they emit. The bigger the dots, the more red light will be emitted. This technology also allows the television to produce more brightness. Furthermore, quantum dots are extremely stable, allowing it to withstand harsh conditions and be used in outdoor applications. Unlike many organic materials, quantum dots will not degrade over time.

As for how to use Quantum Dots on a QLED TV, Samsung is currently the market leader. Samsung’s QLED TVs are highly impressive and compare favourably to super-premium Organic LED displays. Besides, QLED televisions are usually cheaper. They don’t suffer from the same technical issues that OLEDs have. They have also made it easier for manufacturers to scale content from 4K to 8K resolution.

The production of OLED TVs is expensive, which explains the increased cost of these TVs. Therefore, manufacturers are turning to QLED technology as an alternative to OLED TVs. Samsung, for instance, has begun producing QD-OLED TVs, which combines both OLED and Quantum Dot technology. So, in the end, it will be easy to make a decision based on price.

Better picture quality

The question is, “Does a QLED TV have better picture quality than an OLED TV?” The answer is complicated, but it boils down to three basic considerations: your budget, room lighting and expectations. While OLED has better contrast, it’s also not ideal for brightly lit rooms. QLED’s lack of inky black makes it a better choice for less-lit areas. Both screens have a flatter color spectrum, but QLED does offer a faster response time.

Another difference between OLED and QLED is brightness. The latter uses separate backlights, which can be extremely bright. Moreover, quantum dot TVs maximize light and produce more vibrant hues without losing saturation. However, despite their brighter picture, QLED TVs do suffer from light bleed. This is especially apparent when watching movies with wide aspect ratios and intense action scenes. But the picture quality of QLED TVs isn’t without its disadvantages.

The price of a QLED TV varies depending on the brand and model. Most brands make multiple series of the technology, with the more expensive ones performing better than their cheaper counterparts. Quantum dots, for example, are not responsible for the biggest improvement in picture quality compared to their predecessors. Better full-array local dimming, better bright highlights, and a smaller pixel size are all important factors in determining picture quality.

The picture quality of a QLED TV is improved by a blue LED light source. The QLED TV is sandwiched between two layers of LCD panels and a backlight. The quantum dots in the middle layer replace the color filter in front of the LED backlight. QLED TVs also offer a wider color palette, which means that they’re better suited for HDR content. They also last longer than an OLED TV.

Color temperature is another major aspect of picture quality. This controls how warm or cool an image looks. Too much blue or red can make the image appear soft or unappealing. Color temperature can be confusing. To learn more about it, try turning on your computer and changing the mode. Generally, the most accurate mode is Cinema or Movie, which give the best representation of a movie or other material. But what if the picture is soft and unappealing?

Longer lifespan

The average lifespan of an LCD television is somewhere between 30,000 and 60,000 hours, which means it will last four to five years. The same is true for a QLED TV, but the lifespan will depend on how much you use it. A QLED TV can last seven to ten years if you use it moderately, but Samsung says it will last for a little more, around 10 years. It will still break, but not as quickly.

LED and OLED TVs have similar lifespans, but LED TVs use light-emitting diodes. The latter is generally considered to be more durable than LCDs, as it produces clearer images. Samsung’s LED technology is split into two different varieties: OLED and QLED. OLED is the more durable of the two, offering a brighter, more colorful display than QLED. The lifespan is around five to seven years, so if you use your QLED TV for three hours a day, it will last for much longer.

While LEDs are the most popular choice for backlights, a QLED TV is even more energy-efficient. The source of the backlight is an LED, which has a proven track record. QLED displays are able to retain images even after years of use, but they’re less aesthetically pleasing. So, it’s best to keep the backlight on a lower setting and watch TV content in a dark room.

The life of a television is important to know. Most TVs last four to seven years if they’re used regularly, but heavy use will shorten its lifespan by two to three years. But you should do your own cost-benefit analysis to ensure that you get the best television for your money. Samsung TVs are typically made with higher-quality components than their cheaper counterparts, so they should last longer.

Burn-in is a problem with many LEDs. This occurs when a static image, such as a channel logo, appears on the screen for a prolonged period. This is particularly common for news viewers, but you can avoid it by switching to other types of programming. A good rule of thumb is to change the content that you watch every so often. In order to avoid burn-in, you should watch less news and more variety in your viewing habits.


The QLED TV price in Bangladesh is evolving to meet the growing demands of the consumer. The Samsung 55 Inch (138 Cm) QA55Q60AAKLXL (2021 Model) is a good example of a popular TV for its low price. It is available in all major cities. The price is inclusive of bill and warranty. To get a good deal, make sure you buy it at the earliest.

The cost of a 75-inch QLED is considerably lower than the price of a 77-inch OLED. However, the prices of 77-inch OLED TVs can reach up to $2500. And a 75-inch QLED TV costs between $1500 and $2,000. The difference is larger for bigger screens. The LG Q9FN is another good option for high-end consumers, though it does lack extra features like variable refresh rate and HDMI 2.1 bandwidth.

The Samsung Q70T starts at less than a thousand dollars for a 55-inch model and offers a full ecosystem of smart TV features. However, the Samsung Q70T lacks discrete dimming zones and a dual LED backlight that alternates between warm and cool colored LEDs. That results in muted HDR performance. Nevertheless, it is a solid choice if you want a large screen with a high-quality picture.

Samsung and TCL both have multiple QLED series, and their most expensive models are superior to the cheapest models. The biggest improvements in the picture quality are not quantum dots, but rather improved mini-LED backlights and better full-array local dimming. The pricier QLED TVs have better viewing angles than the cheaper ones. This difference in price is reflected in the quality of the TV. This is also one of the reasons why Samsung and TCL have so many different models of the QLED TV.

The Samsung Q60T lacks the full-array backlight and is more expensive than the Q90T QLED. The Q80T has the same high-definition resolution as the Q90T but costs less than half the price. In terms of portability, it matches the best of Samsung’s best 4K sets, while the Samsung Q90T is limited in ports and does not offer Dolby Vision support.
