4K refers to the digital image format with the resolution of 3840 × 2 160, also known as "Ultra HD" or "UHD". This image format has become one of the mainstream digital TV and movie standards, because its pixel number is four times that of the original high-definition image (1, 920 × 1, 080 pixels), and it can present more colors and details.
With the continuous progress of science and technology, 4K technology has been widely used in various fields. In the field of TV, more and more TV brands have launched 4K TV, and the price is relatively close to the people, providing consumers with a higher quality viewing experience. In the film industry, more and more film production companies use 4K technology to make new films to present higher quality and higher definition pictures. In the field of games, more and more games begin to adopt 4K technology, so that players can enjoy a more realistic and immersive game experience.
With the continuous progress of technology, 4K technology will continue to develop. In the future, 4K technology will further improve the resolution, color and contrast to present a more realistic picture effect. In addition, 4K technology will be gradually applied to more fields, such as medical care and safety, to provide higher quality services and experiences. However, it should also be noted that with the development of 4K technology, related equipment and costs may also increase, requiring consumers to do full research and planning before purchasing.
