Today, when it comes to television, we often refer to the phrase “HD TV”. However, many people often misunderstand its meaning that HD TVs are TVs with HD resolution, but in fact, it is not only that. And in this article, let’s learn more about the concept of HD TV with Daotaomt.edu.vn.
What is HD TV?
HD TV (short for High Definition) means high definition television, which is the current standard for home televisions. If you upgrade the screen with standard definition to HD, it means that you will have a TV with significantly increased detail and clarity.
The quality of experience and the ability to display on HD TVs will be higher than conventional standards such as PAL, SECAM or NTSC, which were popular in late 2000 and are now almost no longer produced.
What types of HD TVs are included?
Many of us often confuse HD TV with HD resolution. However, if understood correctly, HD TV is a high definition TV. It includes TVs with HD resolution, Full HD, Ultra HD 4K or even soon, up to 8K. In particular, the two most popular HD TVs today are probably HD resolution and Full HD resolution.
With standard HD resolution, including 2 types:
The type with 1366 horizontal pixels and 768 vertical pixels (also known as HD 1366×768) has 1,049,088 pixels.
1280 horizontal pixels and 720 vertical pixels (also known as 1280×720 HD) with 921,600 pixels are less common.
Full HD screen resolution will have 1920 horizontal pixels and 1080 vertical pixels on a TV screen, Full HD will have 2 times the definition of HD.
TVs with 4K resolution give 4 times more detail than Full HD resolution, and currently 4K is the highest resolution widely available on the market under the name Ultra HD or Ultra HD 4K.
If compared with the same screen size, the higher the resolution of the TV, the sharper and more detailed the display will be.
