Is it only 4K to buy TV? You still have to understand these
There is no doubt that when you walk into the appliance store and want to buy a new TV, you will find that there are not many other options besides 4K TV. Obviously, 720P has been basically eliminated, 1080P has also become a low-end or small-size TV configuration, almost all new high-end flat-panel TVs have 4K resolution. However, 4K resolution is only a basic attribute. If you want to buy a TV that suits you, you need to consider a variety of factors. You may wish to refer to the following. 4K and Ultra HD Ultra HD (Ultra HD) currently refers to image resolution standards exceeding 1920*1080 pixels, and 4K (4096*2160 pixels and 3840*2160 pixels) are naturally included. Of course, 8K is also in the Ultra HD category, so Ultra HD has a broader meaning and 4K is more specific. In addition, 35 companies such as TV manufacturers Samsung, Toshiba, Sony, Sharp, Panasonic, and content manufacturers Netflix, Fox, etc., jointly established the UHD alliance, which stipulates that devices complying with the 4K standard must have at least 3840*2160 pixels of physical resolution. At the same time, the 10-bit color depth can be displayed, which also relates to the HDR 10 standard that we will talk about later. OLED and quantum dots As mentioned above, 4K has become a mainstream TV and video standard. It is a very basic parameter. Manufacturers only advertised the fine effects of ultra-high-definition picture quality when 4K TV was just released, and then began to carry out more In-depth research and development. The 4K TV type is mainly divided into two types, OLED and LCD panel. This is the same as before the 4K standard was introduced, but both have now evolved with resolution. OLED is the main type of panel that LG pushes. It has the characteristics of self-illumination and high contrast. It is recognized as the best picture quality panel technology in the industry. The disadvantage is that it is expensive and the size is limited. LCD, also known as LCD, includes a large number of manufacturers such as Samsung, Sony, Panasonic, Sharp, Philips, etc., and Quantum Dots is a more advanced panel backlight technology that replaces LED phosphors with more advanced quantum dot crystals. The backlight improves the color cast of the LCD itself. But then, quantum dot TV is still a LCD TV, not a brand new display panel technology.
