Since the popularity of 1080p HDTV, the TV industry has been struggling to find the next selling point. In recent years, the quality of the picture has not improved significantly, OLED TV is still a mirage, and 3D has become a famous joke in the industry. The entire TV industry is sluggish, and the only remaining means for manufacturers is to fight the price war. However, at this year's IFA exhibition, manufacturers seem to have found a new direction-that is 4K ultra-clear resolution.
4K belongs to a new generation of ultra high definition television (UHDTV) standard, and its standard resolution is 3840 & TImes; 2160, which is four times that of 1080p. At this year's IFA exhibition, we saw a lot of 4K ultra-high definition TV in kind. The four giants Sony, Toshiba, Sharp, and LG all exhibited 4K ultra-high-definition televisions. The actions of the four giants are so uniform that they even have the same size of 84 inches.
From the consumer's perspective, two years ago, we had been once-the manufacturer vowed that 3D TV will quickly spread, many users have made a big mistake, and paid a lot of money for 3D functions. I haven't watched an authentic 3D TV until now. Will 4K TV lie to us again?
If you have such concerns, we can tell everyone very clearly: no.
Judging from the speed of 4K TV commercialization, 4K is no longer a concept on paper, but will become the next performance benchmark.
The most important difference-the picture
The reason why 3D became a floating cloud is that a major flaw is that we cannot find a unified standard to require and regulate it. Active, passive, refresh rate, brightness loss, even if you know these technical terms, each manufacturer's 3D TV standard is not the same, you can't distinguish clearly between 3D pictures and ordinary high-definition pictures. Facts have proved that there is still a big gap between the effect of 3D TV and the propaganda of manufacturers. Sitting at home and wearing pair of glasses can turn the living room into an iMax theater? Stop dreaming.
Without a unified standard, there are not many advantages in perception, consumers will naturally not pay for 3D. 4K TV does not need to worry about these problems at all.
