So far, multi-size specifications have been realized from 84 inches to 50 inches. The development of 2K to 4K is a trend, and the recent appearance of 8K also indicates that the continuous improvement of TV clarity is the direction of industry development. Regarding the source of the film, the current 2K information source can already achieve 4K conversion through technology, that is, 2K to 4K related compensation technology. Without this 2K to 4K technology, jagged and mosaic will be generated after 2K source conversion. This technology is suitable for all 2K sources, and the effect is better than on traditional 1080p TV. 4K smart TV market prospects According to the overall data analysis of TCL market brand management, there will be 330,000 4K TVs in the national market this year. By 2015, the global 4K TV will reach 2.6-2.7 million sets of export volume, and the market potential is huge. And TCL's 4K products must first quickly enter the market, because there are more than 200,000 units of 80-inch 4K products entering China, and tens of thousands of units. In fact, consumers do not feel enough about 4K products. Since TCL's 4K products entered the market this year, it has been dominated by 55-inch 4K TVs. This size not only reflects the change in 4K resolution, the original full HD TV viewing distance limit has also been completely broken, and the price is also closer to market consumption.
