The display technology market is constantly evolving, and we're seeing a growing number of new TV technologies emerge. In this post, we'll help you understand the acronyms for TV technology, explain how each type of screen works and assess the pros and cons of each option so that you can make an informed choice about what's best for your home entertainment center.
QLED TVs and Mini LED TVs have become two of the most popular products over the last few years and have garnered a lot of attention from both consumers and media alike. But what exactly is a QLED TV? What sets it apart from other types of televisions? And do you really need one? We’ll answer all these questions in this article so that you can make an informed decision about whether or not a QLED TV best meets your viewing needs in 2022.
We'll also discuss another hot topic: What is Mini LED? Many people confuse Mini LED TVs with Micro LEDs (more on those later). While there are some similarities between them, they are actually quite different technologies that each have unique benefits and drawbacks.
You may have noticed that the acronyms for TV technology are growing by the day. As new technologies are introduced and new acronyms are created to represent them, it can be hard to keep track of all the terms. What’s more, television manufacturers often use similar-sounding names that don't necessarily mean much in terms of defining their products or performance.
Here's a quick guide:
LCD: LCD TV is a television display technology based on a liquid crystal display.
LED: LED TV is a type of LCD television that uses light-emitting diodes (LEDs) to backlight the display.
OLED: OLED TV is a television display technology based on the characteristics of organic light-emitting diodes (OLED).
QLED: QLED TVs use Quantum Dot Technology to display a wider range of bright, vibrant colors on screen.
MiniLED: Mini-LED is similar to QLED, but the backlights get even smaller. Taking TCL Mini LED technical as an example, with insight into every detail of every light and shade change, the absolute darkness and brightness are unveiled. Maximize to 4,000+ local dimming zones, (Note: 4000+ partitions are laboratory data, as of 2022, 2,304 dimming zones are manufactured for models) enabling accurate light control and picture details. Local dimming technology. Improve the blooming phenomenon of TV edges against a black background.
Knowing the different kinds of backlights is important because it helps you to understand the differences between TVs with different display technologies.
The backlight is a light source located behind the display, and its luminescence will directly affect the visual effect of the liquid crystal display module (LCM). The LCD itself does not emit light, it displays graphics or characters as a result of its modulation of light.
The most common backlight type in LCDs (and LEDs) is a cold cathode fluorescent lamp (CCFL) and Edge-lit LED. Edge-lit LED is simple, effective, and provides even light to prevent some areas of the display from being brighter than others. Cold cathode fluorescent lamps convert electrical energy into light, which then shines through the display panel. CCFLs have been used since the early days of television, and they're still used today because they produce very bright, wide-angle illumination with minimal power output and low heat production.
Another type of backlight for LCD/LED TVs uses organic LEDs (OLEDs), OLED is the abbreviation of Organic Light-EmittingDiode, known as an organic light-emitting diode or organic light-emitting display. In terms of functional characteristics, the biggest difference between OLED and LCD is self-illumination or not, thus deciding that the screen using OLED technology can be thinner and lighter. LCD pixels are illuminated by a backlight. OLED pixels produce their own light, eliminating the need for separate backlighting lamps.
OLED technology gives off light when an electric current passes through them from electrodes placed on either side of each pixel in a display panel made from thin layers of organic material such as amorphous silicon carbide or polyethylene terephthalate (PET).
With a high-end system, OLED and Mini-LED are currently the premium technologies that will provide the desired images. OLED may have the potential for a shorter lifespan but promises a little better contrast. As for QLED technology, it offers some improvements over traditional LED, it doesn’t always mitigate this blooming and the contrasts between light and dark are not as stark as with some other technologies.
A MiniLED TV is a new type of LED TV that has a smaller backlight than LCD TVs and a better contrast ratio. It also has better color saturation.
TCL is the first to make Mini LED TV and never stop developing. TCL Mini LED TV, with a local dimming technology, offers the best picture quality to you. The local dimming technology helps to optimize the light and shade changes of the TV. With 4,000+ local dimming zones, it can bring more details of images onto your screen. It is an important feature to achieve ultra-high contrast ratio. With it you can enjoy an excellent viewing experience when watching movies or playing games.
In addition to the local dimming technology, with a new algorithm driver, the peak brightness of the LEDs can reach more than 2,000 nits, providing strong support for users to enjoy HDR high-definition movies and games.
MiniLED has the same resolution as other types of LED TVs, and They can display images in full HD, 4K, or even 8K, but MiniLED can display a more stable 4K picture than regular LED. They also offer a wide range of screen sizes and screen brightnesses to fit your needs. MiniLED has a major advantage over other types of flat-screen TVs: their price. Taking OLED TVs as an example, generally speaking, for the same size TV, Mini LED TVs’ pricing is only 60% to 80% of OLED TVs.
A QLED TV is an LCD TV that uses an LED backlight. QLED stands for Quantum Dot Light Emitting Diode and refers to the quantum dots used in these displays. The idea behind quantum dots is that after absorbing blue light (a short wave) from the backlight, they undergo an energy level leap to produce red and green light waves, showing the three primary hues of high purity: red, green, and blue. The quantum dot light material emits when excited by electricity from the TV's power source as well, and this allows QLED TVs to display more vibrant colors than traditional LCD/LED TVs without using any color filters or dyes within their screens (like OLED does). This is why QLED TVs can produce some of the deepest, most vibrant colors we’ve seen on an LCD TV.
Both TVs offer exceptional viewing angles but there are differences in how much color shift occurs depending on where you're sitting relative to the screen (because of the way each technology produces images).
TCL is committed to delivering award-winning picture quality. The company’s award-winning line of Signature Series televisions has received numerous awards.
TCL has worked with industry leaders like Dolby Laboratories to create its own proprietary algorithm that delivers state-of-the-art color accuracy and brightness levels that are 50% brighter than other OLED TVs on the market today.
In conclusion, it’s important to know that there are a lot of different TV technologies on the market today. Not all of them are right for everyone, and it’s important to choose the one that best meets your needs. Whether you want to get a QLED TV or a mini LED TV in 2022, TCL TVs have got you covered.
