With the rapid pace of technological advancement, we often wonder what certain electronics acronyms mean. In the case of TV's, there are several: LCD, LED, QLED, HD, Full HD, 4K, 8K etc. 434s8
Therefore, in a simple and general way, the showmetech prepared a guide for you to understand how to assemble a TV and, thus, understand what each type of product can mean in your experience. Whether watching channels, browsing the web or playing video games, each TV has its own particularity. Come on?
Plasma, LCD and LED: TV screen technology 1v4ed
Now, let's talk about TV screen technology. That is, the specifics of mounting the TV . There are currently some technologies and we highlight the main ones below.
I'm going to buy a Plasma TV! 6r1l54
You may not even the last time you heard that phrase. Younger people reading this guide probably don't even know exactly what it is. The fact is that the plasma TV was a great evolution of the image and, therefore, was the best seller at the beginning of the last decade.
This TV model caught the public's attention, as it was the origin of straight screens, which allowed a better view from various angles of the same space. Today, this model is no longer sold and gave way to the technology that is much better known, the LCD.
Is this TV LCD? 4gn41
Think of a plate of crystals with a source of light emanating from behind it, which es through that plate and then produces the colors. This is how an LCD (Liquid Crystal Display) screen works. Almost all the digital equipment we know today is made of this technology: clocks, s, billboards, monitors and, of course, televisions.
In their case, those who have this technology are known for having low power consumption, spending half as much as a screen with the previous technology.
In addition, LCD TV's also have zero emission of electromagnetic waves. That is, exposure to this type of screen is not harmful to health, except when it is done in excess, obviously.
What is an LED TV? 1y5jh
We could classify the LED screen as an advanced LCD. This is because they are very similar in their structure and the difference is in the LED that is added to this one and further strengthens the formation and visualization of colors.
Experts say that consumers perceive large differences in televisions over 32 inches, as these sizes allow for greater image diffusion.
Another point is that, in the case of the previous screen, more technical people perceive dark spots that are visible due to lack of light, while in this type of TV the screen is even brighter.
QLED or OLED? Is there still more? a4u63
Despite the similar name, QLED and OLED technologies don't look alike. Both are evolutions of LED, with OLED technology owned by Samsung. There are other brands that sell products with both technologies, but only these companies manufacture the respective displays.
In addition to the LED concept, which we have already explained, the “O” refers to the organicity that OLED screens have. In this case, televisions are produced with organic diodes that emit and control their own light. That is, as the images through the TV, the equipment itself takes care of adjusting the light to improve the experience of those who are watching. These TVs are known for their thickness, which can reach the same size as a cell phone.
The “Q”, on the other hand, refers to the quantum dots present on the TV. In this case, the QLED screen itself generates these dots that can produce the colors faithfully. These TV's are known for their brightness and their performance in environments with any type of lighting.
Full HD, HD, 4K and 8K: that pixel and TV resolution 1g17p
They added the words "picture” (image) and “element” (element) and formed the term “pixel” which, in Portuguese, means “element of the image”. It refers to the composition of the image on a screen. The digital image is formed of points that, together, allow us a complete visualization.
Let's think, for example, of a camera, whether digital or mobile: the more zoom we apply, the closer the image will be to the target. However, with each zoom application, the “squares” that make up and form the image become more noticeable.
O pixel is present on all displays, from smartphones to giant digital billboards. And, for the screen to be complete by an image, the TV makes use of these pixels, scaling them according to its size.
Therefore, the greater the presence of pixels, the better the definition of the image. That's because, the more "square" the TV has, the less it will need to resize the displayed image to offer it complete to those who are watching.
Below we separate each screen definition degree and the respective amount of pixels. When reading, consider the first number referring to the width and the second referring to the height of the screen.
HD Resolution — High Definition (High Definition) 5l165k
HD resolution was a revolution when it hit the market, as it was introduced along with “thin screen” TVs. If compared to the analog resolution, which was in effect until then, this one has twice the quality. Here, the TV must have at least 1280 x 720 pixels, reaching almost 1 million pixels spread across the entire screen.
Full HD Resolution (Maximum High Definition) 442sm
Even with a good resolution, technology companies wanted to develop products that gave even more definition to images. That's when the Full HD resolution came about, which has more than 2 million pixels (1920 x 1080), double the previous one.
- Samsung Full HD LED 43″ for $ 1.889
- LG Full HD LED 43″ for $ 1.889
4K Resolution 3as4r
Currently, most screens sold in Brazil and worldwide are made with this resolution. Also, almost all streaming and media players this resolution. Here, it's 3840 x 2160 pixels, making a whopping 8.294.400 pixels on the screen.
- Samsung Crystal 4K LED 43″ for $ 2.199
- LG 4K LED 50″ for $ 2.699
8K Resolution 31365o
8K resolution is the highest quality and sharpness index on the television market today. There are more than 33 million pixels, divided into 7680 x 4320, which form the image of this screen. Typically, TVs with this resolution are over 50” inches and have the highest sales value.
Despite this, there are few contents already available in this resolution. Currently, productions are made mostly in HD or Full HD and now, in Brazil, productions are gradually being created for 4K resolution.
- LG 8K OLED 65″ for $ 11.684
- Samsung 8K QLED 75″ for $ 32.539
Smart TV — the smart TV 2r6a13
Here we enter into a concept that is not necessarily linked to the previous ones. According to literal translation, an equipment smart It is a smart device, which can be connected to other devices over the internet.
In the case of televisions, the android system installed. With this type of television, you can access various video streaming services — such as Netflix and Amazon Prime Video — and music, in addition to browsing the web and mirroring your smartphone's screen.
It is important to note that to enjoy all the benefits of a smart TV, the device must be connected to the internet, either by cable or Wi-Fi. Otherwise, you will only be able to use the equipment's basic functions, which leaves it like an ordinary TV, without intelligence.
On the market, there are accessories that turn a basic TV — with an HDMI input — into a smart TV, such as the Google Chromecast or the Amazon Fire TV, and are at very attractive prices for those who do not yet intend to purchase a new smart TV. Chromecast 3 can be found for R$355 in Americans.
