The development of 2K to 4K is a trend, and the recent emergence of 8K also indicates that the continuous improvement of TV clarity is the direction of industry development. Regarding the source problem, the current 2K information source can realize 4K conversion through technology, that is, 2K to 4K correlation compensation technology. If there is no such 2K to 4K technology, the 2K source will produce sawtooth and mosaic after conversion. This technology is suitable for all 2K sources and is better than 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 this year's national market. By 2015, global 4K TV will reach 2.6-2.7 million units of export volume, and the market potential is huge. TCL's 4K products must first be quickly cut into the market, because 4K products were originally 80-inch into China with more than 200,000 units, and there are tens of thousands of units. In fact, consumers are not feeling enough about 4K products. TCL's 4K products have entered the market since the beginning of this year, with 55-inch 4K TVs as the mainstay. This size can not only reflect the change of 4K resolution, the original full HD TV viewing distance limit is also completely broken, and the price is closer to the market consumption.
