In 2013, the brand manufacturers have begun to launch a series of 4K television, advertising has begun to play out, and have the store shelves. What is 4K TV, exactly? and what is the difference between 4K and UHD TV?

     Let me talk about market developments, now with the TV size is increasing, if a screen is 1920 x 1080 pixels, the pixels can be more rough, and users’ demand for quality became higher, so in order to obtain a more delicate picture, screen composition displayed in pixel size must be the same or even smaller, so it is essential to improve the resolution.

     As to technical progress, with the promotion of Apple products, the phone's screen has reached the extent of the retina screen, which means the pixels are so small that naked eye cannot distinguish theoretically, therefore resolution of TV screen should also be improved to keep up.

     4K refers to resolution, currently the traditional HDTV resolution is 1920 × 1080. 4k TV, as the name suggests, its resolution is 4 times that of traditional HD TV 1920 × 1080, which is 4096 × 2160 pixels.

It is four times the 2K projectors and HDTV resolutions, belonging to ultra-HD resolution.
Currently, the US Consumer Electronics Association has announced that 4K TV is named UHD TV officially, which is abbreviation for Ultra High Definition Television and stands for "ultra high-definition television."
Back in August 2012, the International Telecommunication Union had demonstrated that 4K TV (resolution 3840x2160) and 8K TVs (resolution 7680x4320) were UHDTV.

Namely, resolution for 4K belongs to one of the species summarized to UHD, with resolution it contains is more than 4K. However, 4k is generally regarded as UHD in the market, just with their name different only. 4K is similar to its nickname used in factory and consumers, while UHD is considered to be its official name.
