Have you thought of how confused and amazed you will be when you visit electronics stores to buy a TV screen for your home?! You will find yourself surrounded by a lot of shapes, types and brands! For a moment, you will think that they are all the same and you will not be able to differentiate between the types that you see, but if you look closely at the characteristics and specifications of each TV screen, you will recognize the huge differences between them, thanks to the rapid technological progress in the past few decades.
TV brands are creatively using new technologies to generate the best viewing experience! Of all these powerful options available to you, the decision is ultimately up to your style, preferences, and needs. In this article, I will show you the 5 best types of TV screen, and you are totally free to decide what suits you from among them:
1. QLED
QLED screens are the next generation of LCD screens, which were only launched a few years ago. It was called QLED because it symbolizes the name of the technology used in its manufacturing. The first and most important letter is "Q", which means in English Quantum Dot, meaning a quantum dot. As for the rest of the name LED, it means, in English, a light-emitting diode, which is a lighting system that has been used since Several years in most LED and LCD screens.
Small nanoparticles (quantum dots) are emitted in the LCD screen, which greatly improves the quality of the color, brightness and luminance filters. Although OLEDs have better contrast ratios than QLEDs, QLEDs are larger, have a longer life, are energy efficient, and are not prone to burnout. As for the price, a QLED screen is more expensive than an LCD TV. QLED screens are the middle ground between LCD and OLED screens in that they combine quality and price.
2. OLED
The name OLED means "organic light-emitting diode", this name was used to describe the type of TV screen, because it is basically an organic compound when an electric current is passed through it that emits light. This means that the OLED screen does not need a large old backlight, it mainly depends on the pixels on the screen that light up on their own (self-lighting).
In general, OLED screens are much better than traditional LCD screens because they are more energy efficient, they do not need a huge backlight that consumes a lot of energy, in return this feature makes the screen much thinner and prone to breakage. One of its most important features is also, improving image quality, as you can see more accurate blacks while watching dark TV or movies, unlike regular TVs. As for the prices, they are the most expensive among all other types.
3. HDR
HDR stands for "High Dynamic Range", and refers to the screen's ability to display extremely bright and light scenes and extremely dark scenes, thus viewing images more naturally and realistically even in a wide contrast range. It is based on the HDR10 standard, which relies on static data to playback images, and adjusts the settings of the entire video when it is played back.
It has better color accuracy and contrast compared to normal screens, and is now used in TV screens, smartphones, and others. While HDR technology provides a better viewing experience for users, three better dynamic standards have recently appeared, including: HDR10+, Advanced HDR, and Dolby Vision.
4. Dolby Atmos and Dolby vision
With the continuous development in sound and image technologies and the practical applications of these technologies on television and phone screens, companies always strive to provide higher quality in terms of sound and image so that the user can enjoy a better viewing experience every time, and despite the wide spread of HDR technology on screens, Dolby vision technology appeared as a better competitor in terms of quality, as HDR technology relies on image information in a linear manner, while Dolby Vision adjusts according to what appears on the screen, in order to always show image quality and provides a contrast ratio and brightness four times more than HDR.
As for Dolby Atmos, instead of improving the picture in Dolby Vision, Dolby Atmos reproduces high-quality sound. It can locate specific sounds in a specific area (at the spatial level) and can provide up to 128 audio tracks; Netflix shows movies that use this technology, for example. Among the TVs that support this feature are: Sharp 42-inch Smart TV, Toshiba 50-inch Smart TV, and Sharp 70-inch TV.
5. Plasma
It was the first type of flat screen to hit the market about ten years ago. In its principle of operation, the plasma screen depends on the presence of two plates of glass between which there is gas (mostly neon gas), on which there are a group of electrodes that send electric charges that make the gas glow between the two plates, and then the image appears on the screen.
Among its advantages: It is considered one of the best types in terms of color contrast and clarity of the image and its ability to display images quickly, as it gives you the experience of watching football matches, car races and others in high resolution, and is characterized by its long life span of up to 16 years.
On the other hand, there are some drawbacks to this type of TV screen, as it has a glass screen that reflects light on it, the viewing angle is low, and its quality decreases with time, and it is usually of large sizes that fit in large areas and there are no small sizes of such screens.
