According to industry insiders, compared with 4K TV, 8K TV has been recognized by the ultra-high-definition television standard with a resolution of 7680×4320. TV will be greatly improved in terms of color gamut, color depth, color gamut, grayscale, frame rate, standard viewing distance, viewing angle mode, and audio, and it is closer to the human eye. Although 8K can bring clear picture quality close to the limit of human eye recognition, but the current 4K source still has some distance from us. Can we see 8K source in our lifetime? Detailed 8K120fps transmission specification, 8K resolution The rate is approximately analogous to 33 million pixels, while 120fps means that there are 120 3,300,000-pixel images per second for streaming media playback. This amount of data is very large. It is understood that even if the video in the 8K format is only one minute, it can occupy a full 194GB of space. With our current network or other video carrier, it is not enough to handle the huge 8K video capacity. At the same time, the 22.2 channels of the 8K standard are even more exaggerated. Speakers that need to pass through the upper 9-channel, middle 10-channel, and lower 3-channel three-layer configurations, as well as the two-channel low-frequency audio (LFE) loudspeakers Ten, nine, and three horns were placed in the horizontal position of the listener's ears, above and below the listener's ears, and two subwoofers consisting of 36 small woofer units were also provided. There is the price, as was the case with the original 4K TV, 8K TV is definitely a lot more expensive. And 8K TVs generally match oversized screens, 98-inch, 100-inch and so on, and the price is certainly quite exaggerated. This is why Sharp still has not officially pushed 8K TV. In addition, if you think 4K TV is not necessary, you don't have to worry about 8K TV. After all, resources are also a big problem. At least in the 4K resource eco-industry to a certain stage of maturity, when manufacturers will naturally promote 8K TV, then it is the best starting point for 8K TV. As a result, from the current point of view, 8K TV's attack will not create much threat to 4K TV. However, in the future, with the maturity of technology and the addition of many TV manufacturers, 8K TVs will replace 4K TVs, which is only a matter of time. Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions. 1
Preparation of raw materials - including visual inspection of raw materials, chemical composition analysis, ingredients and weighing of various ingredients according to the calculation of ingredients. In addition, also includes refining agent, metamorphic agent drying and weighing.
2
Smelting - adding materials in a furnace in a certain order to melt them into alloys of uniform chemical composition.
3. Pre-furnace test -- after the alloy is evenly melted, sample and test to check whether various chemical components meet technical standards.
4
Adjustment of composition - If the chemical composition of one or more alloys is found to exceed the technical standard after testing, adjustment shall be made to make the chemical composition meet the technical standard.
5
Refining - After chemical composition requirements, a refining agent is used to remove dissolved gases and entrained solid particles from the alloy.
6
Refining metamorphism - adding appropriate refiner and modifier to aluminum alloy liquid to improve mechanical properties and mechanical cutting properties of the alloy, etc.
7
Casting -- casting aluminum alloy with qualified chemical composition, good metamorphism effect, gas content and slag content to meet the requirements into ingot, into bales.

8K TV is about to attack the current 4K TV can be threatened
Recently, it is reported that Sharp will mass-produce 8K TVs next year and promote 8K TVs worldwide. In the second half of this year, Sharp will use the Kameyama Plant to test and mass-produce 8K TVs. This means that 8K TVs have already been launched. . For the 4k TV that has just been popularized, whether it is threatened may be discussed together.
