Modern technology does not stand still, and televisions bought five years ago are becoming obsolete, giving way to new, more advanced models. Everyone who is thinking about buying a new TV, should familiarize themselves in advance with the latest technology.
If you want to buy a TV, read the following information carefully.
Determine what size TV you need. When it comes to choosing the right size TV, the deciding factor is how much space is available for it in your room.
There's also the question of how close viewers sit in front of the unit and what picture resolution is preferred.
- For small to medium-sized TVs, Full HD resolution is usually sufficient.
- For a 48-inch screen, a 4K screen is a good choice, otherwise the picture will look grainy.
Now let's understand the technology.
Liquid Crystal Technology LED and LCD TVs
LED TVs are still very popular with many consumers because these devices are much more affordable. An LED TV uses LEDs as background lighting and produces a picture using liquid crystals. These televisions are suitable for small rooms or in the kitchen.
This TV technology, developed by Samsung, works using what's called quantum dot technology. There are billions of nanocrystals of different sizes on the film, which are arranged inside the TV. These crystals glow red or green because of the blue backlight. The combination of these three shades gives a white light.
Many consumers choose these devices for viewing stable, high-contrast images.
QLED technology is also suitable for recognizing minute details in dark images. The picture looks equally good from all sides - unlike the technology used in LED and LCD televisions.
In a smart TV with OLED technology, organic LEDs create rich color and high-contrast images. Unlike LEDs and LCDs, each individual pixel in an OLED device is a separate light source.
However, the disadvantage of OLED technology is that the display can burn out from still images that have been displayed for hours. Therefore, you do not need to view pictures in such TVs.
Smart TV technology
There are no fixed performance standards for Smart TV devices. Inexpensive models, at first glance, can meet personal needs. However, these devices may not contain all the applications suitable for streaming web content.
High-end devices also integrate additional interfaces that connect to the network via USB.
In addition, some models have HDMI or CI connectors, so the TVs can be connected to Blu-ray players or game consoles.
4K and UHD technology
The 4K designation indicates an image resolution of 4096×2160 pixels.
"UHD" is an abbreviation for "Ultra High Definition," referring to a very high resolution of 3,840×2,160 pixels.
However, it has now become common practice to use the terms UHD and 4K as synonyms.
As a side note, if you want to use your TV as a gaming screen, look out for screens with built-in HDR functionality. This so-called high dynamic range guarantees the lowest possible latency and high refresh rate.
8K TV technology
An 8K TV offers a picture resolution of 7680×4320 pixels. This means that the resolution of this model is about four times that of 4K. However, in order for the pixel density to pay off, an 8K TV must also be large enough.
This size and the technology associated with it, in turn, affect the price. If you want to afford this luxury TV, you should choose a premium model from the Samsung brand.
With all of the above in mind, you can choose a TV depending on your preferences and capabilities.
