Understanding 4K Ultra High Definition Television II

自从1080p的高清电视普及，电视行业一直在苦苦寻找下一个卖点。近几年，画面的质量没有显著提高，OLED电视仍然是海市蜃楼，而3D则成了业内著名笑柄。整个电视行业低迷不振，厂商们剩下的手段，也只有打打价格战了。不过，在今年的IFA展会上，厂商们似乎已经找到了新方向——那就是4K超清分辨率。

4K is a new generation of ultra-high definition television (UHDTV) standard, with a standard resolution of 3840×2160, four times that of 1080p. At this year's IFA exhibition, we saw a large number of 4K ultra-high definition televisions. Sony, Toshiba, Sharp and LG, the four giants, exhibited 4K ultra-high definition televisions at the same time. The actions of the four giants were so uniform that even the size was exactly the same 84 inches.

From the perspective of consumers, we have been fooled once two years ago - manufacturers at that time vowed that 3D TV would quickly become popular, and many users who bought TVs were fooled and paid a lot of money for 3D functions in vain, but they still haven't seen a genuine 3D TV. Will 4K TV fool us again?

If you have such concerns, we can tell you very clearly: No.

Judging from the speed at which 4K TVs are being commercialized, 4K is no longer a concept on paper, but will become the next performance benchmark.

The most important difference - the screen

One of the major flaws of 3D is that we can't 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 standards are different, and you can't tell the difference between 3D images and ordinary high-definition images. Facts have proved that the effect of 3D TV is still far from what manufacturers advertise. Can you turn your living room into an iMax theater by wearing a pair of glasses at home? Don't dream.

Without unified standards and little visual advantage, consumers will naturally not pay for 3D. However, 4K TVs do not have to worry about these problems at all.
