Smart TV shipments in 2014, the best performance of LeTV TV is only a million units, but in 2015, the double eleventh sold 38.6 units, and smart TV is flying into the homes of ordinary people. I believe many people are thinking about it. Change the old TV at home. In addition to intelligence, there are still many new concepts in the smart TV industry. Before you buy a smart TV, you need to understand.
1, 4k
Reference factor: important
4K TV refers to a TV with a resolution of 3840×2160 pixels. Its resolution is 4 times that of 2K TV. At this resolution, the viewer will be able to see every detail in the picture, each close-up. It is similar to Apple's proud Retina screen concept, except that the retina screen is explained from the viewing experience, while the 4K TV is explained in terms of technical parameters, but 4K TV may not be able to achieve Retina effect.
Whether a TV supports 4K is determined by three factors: the resolution of the display itself, the processing power of the TV or TV box, and whether the content itself is 4K. Now 4K content is getting more and more abundant, it is recommended to consider only 4K when purchasing TV.

2, the surface
Reference coefficient: general
In theory, the plane is still not the most suitable shape for the human eye's physiological structure, because the lens of the human eye is convex lens-like, and the focal plane formed by the focus is a spherical arc surface. The picture of the flat-panel TV lacks three-dimensionality and presence, and the screen The bigger the distortion, the more obvious the distortion. Curved TV means that the TV screen has a certain curvature, which is more in line with the visual habits of the human eye. When watching the program, the sense of presence is stronger. Just like the difference between the IMAX 3D movie screen and the ordinary 3D movie screen, the curved surface technology is divided into the original song. Screen and physics screen technology, physics screen will be the mainstream of the future.
However, the current surface technology is not very mature, the cost is higher, LG's OLED 4K TV sells 60,000 yuan, domestic curved TV will not be less than 5,000 yuan, so curved TV is also a luxury in TV.

3, quantum dots
Reference coefficient: general
A quantum dot is a nanomaterial composed of a small number of atoms. It has unique photoelectric properties and is stimulated by electricity or light. It emits very pure high-quality monochromatic light of various colors according to the diameter of the quantum dot. Backlights using quantum dot materials are the purest backlights available today. Quantum dot TV has improved in color gamut value, brightness, and color vividness. The Korean media said that Samsung and LG's quantum dot TV technology is basically mature and ready for mass production. Domestic TCL and other manufacturers have already launched corresponding products.
On the way to quantum dot TV, the cost is tens of thousands. Philips, TCL has launched quantum dot TVs below 10,000 yuan. For example, the Philips PUF6850/T3 55-inch quantum dot smart TV has been reduced to 5888.00. If you are too expensive, you can consider purchasing a 1999 yuan quantum dot computer monitor equipped with a TV box.

4, HDR
Reference factor: weak
Is the word HDR familiar? Many mobile phones can choose to turn on HDR, which is a high dynamic range. Apply HDR technology to your TV with high contrast, clear and dark, and bright colors. This fall, Samsung, LG and Sony's high-end TV models are equipped with HDR technology, 4K TV affects the resolution, curved TV affects the sense of presence, quantum dot TV affects color, HDR optimizes the overall picture. But to be honest, if the phone is turned on for HDR, the perception is not so obvious.
It is worth noting that HDR technology, like 4K, requires HDR technology when content shooting, otherwise it is still useless. Now there is not much content like this, and China has almost nothing. HDR technology TV has not been launched in China, there are many products abroad, the cheapest Samsung JS8500 65 å‹ also 2500 US dollars, I believe that many domestic TV brands will introduce HDR technology.
