This year's TV industry is very lively. The voices of the old and new players are waving one after another. In the content and technology division, today's emerging Internet companies have gained more and more living space. They are getting more and more in the Internet's enthusiasm. Much right to speak. From a technical point of view, traditional TV manufacturers have accelerated their respective display technologies: Sharp's "Red Yellow Blue Green" new generation of four-color technology, Samsung's SHUD TV, LG's first 4K curved OLED TV, and Hisense's second generation Laser cinema TV, TCL Quantum TV, Skyworth OLED ultra-thin TV; from the market layout, the traditional color TV manufacturers also learned mobile phone manufacturers, have established a separate Internet TV brand, such as Skyworth and Cool open, Konka and KKTV, Lenovo With 17TV; and Internet TV brands began to vigorously layout their respective ecosystems, such as LeTV's open closed-loop, millet's channel is king; at the same time, this year also produced a considerable number of new faces, micro-whale TV, CANTV, Storm TV, popular TV. The field of smart TV is like blasting a pot.
However, in spite of this, it is impossible to stop the trend of content-based bonuses. Videos, games, shopping, and live broadcasts have become large-screen, outward-facing traffic windows. Internet TV manufacturers have become more comfortable with this trend. The battle for television is no longer just a matter of hardware technology. Under the guidance of the Internet+, Internet smart TVs have begun to embrace more attributes. Traffic transformation has also been grafted onto smart TVs. Therefore, ecological construction has the strongest desire in this year's television field. Today, on this basis, we conducted an in-depth year-long horizontal review of the most popular Internet smart TVs in 2015 to see what kind of immortal talent the Internet+ has created.

American National Standards Institute (ANSI - American National Standards Institute) A voluntary organization of companies, governments, and other members. They negotiate standards-related activities, review US national standards, and work hard to improve the U.S. position in the international standardization organization. In addition, ANSI has developed international standards and U.S. standards related to communications and networking. ANSI is a member of IEC and ISO. The ANSI contrast ratio is the contrast ratio measured using the ANSI standard (ANSI - American National Standards Institute) test method. The ANSI contrast test method uses 16 black and white color blocks, and the average value of the 8 white areas is the average value of the 8 black areas. The ratio is ANSI contrast. Compared to the dynamic contrast converted from the brightest point and the darkest point in the screen, this means that the reference value close to the average contrast is more realistic, because the user will not notice the screen because of the brightness of the screen. The difference in value is large and the merits and demerits of the picture are defined, but whether the detail of the picture is more or less based on the difference between the brightness and darkness of the dynamic picture is determined.
Color gamut:
In computer graphics processing, a color gamut is a complete subset of colors. The most common application of color subsets is to accurately represent a given situation. For example, a given color space or the color rendering range of an output device. (Using the internationally accepted CIE 1976 color gamut standard)
Levels:
The color scale is an exponential standard that expresses the brightness of an image, that is to say, the color index. In the digital image processing tutorial, it refers to the gray scale resolution (also referred to as gray scale resolution or amplitude resolution). The fullness and fineness of the image are determined by the color scale. The color scale refers to brightness and color, but the brightest is only white, and the darkest is black.
