Crisp sound and does not have a design that meets the needs of current use Because TVs in the past used to be an "analog" transmission system that was highly sensitive to interference. As a result, it results in unclear images, double images, lines on the screen, black-and-white images, or unclear color images.

But as technology has come in more now TV has been developed. “Digital system” helps increase clarity. Highly resistant to signal interference Along with being able to support a variety of channels, including the "IPTV system" or what we know as "Smart TV", with high-speed internet technology being applied together.

What kind of TV is right for you?

Choosing a TV must be a bit overwhelming. Because it is an electrical appliance that is quite expensive. Therefore, no one wants to replace it often unless the TV is damaged or damaged beyond repair. Therefore, when choosing to buy one, you may have to give extra consideration.

TVs usually have different designs, such as flat screens, convex screens, tabletops, stands, or wall mounts. But overall, we will divide TVs according to the type of screen that has been produced with new technology. Related as follows:

• CRT TV

CRT TV (Cathode Ray Tube Monitor) or glass screen TV, the back of the TV will be convex. Which is an early TV that has been with our homes since ancient times. Even though nowadays there are hardly any for sale, some houses still use them. This type of TV receives an analog signal. It has a phosphorus compound coated on its surface and works by shooting an electron beam onto the surface of the screen. When electron light hits phosphorus, it glows, creating a projection for you to see.

• LCD TV

LCD (liquid crystal display) TVs were the first flat-screen TVs to use CCFL bulbs, which look like coffee bulbs arranged horizontally, as the light source. It shines through solid and semi-liquid crystals. There are three colors called liquid crystals, that is, red, blue, and green, mixed together until they come out in different colors. The advantage of this type of TV screen is bright colors. But the color may be slightly distorted due to Response Time, which is a pixel response speed of only 2 ms. Suitable for use in rooms with high brightness, such as living rooms, reception rooms, restaurants, airports.

• LED TV

LED TV is the most popular TV today. It was developed from LCD TV using 3 miniature LED bulbs called Liquid Crystal in 3 colors: red, blue, and green. It is a solid, semi-liquid crystal. It keeps twisting its body to allow the light from the LED bulbs to shine through and come out in various colors. The advantage of LED TVs is that they produce better light than LCDs, consume less power. and the TV body is even thinner

But not only that, for LED screen TVs there are also 3 other formats. that will give different display performance as follows

1. Edge LED screen : It is a placement of light bulbs around the edge of the TV screen. That will help adjust the thickness of the TV to be thinner, consume less power, but the colors of the images displayed on the screen may not be that good.
2. Full LED screen : It is a TV that has light bulbs arranged all over the screen panel. causing the device to be thicker But the colors of the images appear sharper, realistic, and increase the enjoyment of viewing more.
3. RGB LED screen : There will be LED lights in all 3 colors arranged all over the screen panel. That causes the color mixing to be more dimensional and realistic than Full LED.

• OLED TV

It can be said to be a modern TV with pixels that can generate light on their own without having to rely on light bulbs like LCD or LED. The highlight of the screen is that it is like a flexible film, so the screen can be developed to have a beautiful curve. Can be seen in every corner of the eye You can also precisely control the position and brightness of the light. Some formats may be able to control the shades of light that are red, green, and blue, so it is quite another type of TV that helps create realistic colors.

• NANO CELL TV

The Nano Cell TV is a small, 1 nanometer thin, polarized film that removes impure light from the RGB filter on a pixel-by-pixel basis to display only true-to-life colors. and accurate on the screen

• QLED TV

This type of TV is the latest TV innovation that uses Quantum Dot technology, which is a high-resolution nano-sized conductive material used to replace the old diode tube, helping to result in sharper colors. Whether the environment is bright or dark It can always provide good quality colors of the projected images.

TV technology Modernity that you can choose as you wish.

We have already known the TV types above. Let's get to know some of the technology that comes with the TV. Because these technologies equally affect the decision to buy a TV.

• Monitor resolution

The reason why you should check the resolution of the monitor before purchasing it is Because the display of the screen may create a great experience in watching movies, documentaries, or news, making you feel entertained and satisfied while relaxing and watching TV at home. No need to feel frustrated when the picture is blurry and unclear. There are basically 5 levels of screen resolution:

1. SD (Standard Definition) : is a standard definition level of 720 x 480 Pixel with a display resolution that is less sharp. It's a relatively old standard, mostly found in analog TVs.
2. HD (High Definition) : is the resolution standard for monitors. It has a high resolution of 1280 x 720 Pixel and is still popular today.
3. Full HD (Full High Definition) : is a resolution that is widely popular today as it has a full high definition of 1920 x 1080 Pixel, helping to watch movies. sports or various TV programs to their full potential
4. UHD (Ultra High Definition) : Also known as 4 K, it is an ultra-high definition level of 3840 x 2160 Pixels, which is 4 times higher than Full HD. This level of resolution allows us to view images with clarity. Sharper and more realistic
5. 8 K : has a resolution of up to 7680 x 4320 pixels, which is 4 times higher than 4 K and 16 times higher than Full HD, creating realistic, detailed images. But at the same time, it may be expensive as well

• Helping control the brightness of the TV screen

This technology in technical terms is often called Dimming, which is usually in LED, QLED, OLED TVs that help reduce light interference from light sources in certain spots and can display black, white, gray and contrast. deeply. For example, if the picture on TV is a night sky with clouds or the moon This technology dims the lights in the darker parts of the sky, creating a completely black image that lets you see details of the moon or clouds.

• Connecting to social media

It cannot be denied that social media nowadays has quite an influence on our lives. Because it is something that facilitates us to access news or various media channels more easily, therefore, it may be a factor that causes manufacturers to invent a new type of TV. Which everyone is probably familiar with by the names called Smart TV and Android TV (Android TV), that different as follows.

1. Smart TV : Works with OS operating system. Most of the were invented. To use with Smart TV to help viewing news. Or to put it simply, it is a TV that requires working with the internet and applications. Some brands have touch support. Voice commands via remote control and can share the screen display from a smartphone The tablet can be displayed on the TV screen. But there is a slight disadvantage in that it can load fewer applications. Often it's just the mainstream applications that people like, such as YouTube, Netflix, Disney+ Hotstar, Apple TV or Prime Video.
2. Android TV : It is the most popular operating system from Google. Use the operating system to connect to Google's Play Store, so you can download and install a variety of applications. It can also be connected to various accessories such as keyboards, mice, game joysticks.

In the beginning because you have to complete the registration process before using it. And the system may be delayed if the device's specs are too low.

If anyone is deciding to buy a TV. In addition to the technology that we have introduced You should check the appropriateness of use together with the purchase budget. For example, for people who don't have much time to watch TV. You may also buy a TV that is the right size and has a medium resolution. But if you are a person who watches movies, series, , you should choose a resolution that enhances the viewing experience, such as Full HD, 4K.
