For many families today, television is a common home appliance. At the time of purchase, everybody usually compares many things, regardless of the parameters and performance, have several TV horizontal contrasts, and choose the most suitable one among many complicated and difficult technical terms. I believe that many people have experienced this period of "selective phobia," then what are the most important quality factors for television? Today, let Xiaobian take everyone to take a look. 
The concept of resolution is believed to be no stranger to everyone. For display devices, the resolution directly determines the fineness of the picture. The higher the resolution of the display device is, the higher the image quality that can be displayed is, and the higher the visual performance that the human eye can see.
The once popular 1080P refers to the resolution display format. The physical resolution of a device with 1080P resolution can reach 1920*1080 pixels. TVs currently on the market are generally 2K or 4K TVs. Compared with 1080P, the 4K pixel has been increased four times, with a resolution of 3840*2160 and effective pixels of 8.294 million. After more than three years of development, the popularity of 4K TV has increased year by year. Due to its excellent visual effects, it has gradually become the standard for television. Although 4K already has good clarity, it does not mean that TV will end at 4K. Sharp has already developed 8K TVs and believes that the quality of TVs in the future will also increase.
The term color gamut coverage may not be heard very often, but in fact it is also very much related to picture quality. TVs with a higher color gamut coverage will have more expressible colors, and the degree of convergence between each color will be even better. At present, the coverage of color gamut of TV is constantly improving, and it can even reach a level of about 98%. The picture presented by such a television is closer to the true color.
In addition, brightness has a great influence on picture quality. Many people once thought that the factors of image quality include only parameters such as color and resolution, but they did not think that brightness could also affect the picture. In fact, if the TV picture dramatically increases the brightness, the picture quality will be greatly improved. Last year, even if HDR began to be popular in TV products, HDR technology could enhance the brightness of the screen while letting light and dark details appear. From the point of view of the human eye, the increase in brightness will make the dull picture brighter, and the colors will also be more realistic in the highlights. There are also many manufacturers that have introduced television light control technology, which can adjust the light intensity through the control of the backplane, and also have the function of improving the image quality.
