Television is becoming more and more intelligent, so how do we choose to buy TV? How to distinguish good from bad?

First, how to identify the quality of television
First, it depends on whether the display screen is hard screen or not.
Whether the display screen is hard or soft is caused by the arrangement of liquid crystal molecules. Hard screen category has ADS screen and IPS screen, soft screen category has VA screen and TN screen. Generally speaking, the response speed of hard screen is faster than that of soft screen. For soft screen, the response speed of VA screen is slower than that of hard screen, and the color uniformity of screen is poor. Especially when you use soft screen TV to surf the internet, the text of web page is sharpened too seriously and looks blurred. For TN screen, its display perspective is standard. It's difficult for a family to watch TV.
So it's better to buy TV and choose hard screen TV. So how to identify whether the TV screen is a hard screen? If you press the screen with your finger, the hard screen will not change. The water ripple on the screen is the VA screen, and the plum pattern is the TN screen.

Secondly, it depends on the resolution of the display screen:
At present, the resolution of the mainstream TV is UHD (3840 * 2160), which is the 4K TV. But also called 4K TV, some are Real UHD (true 4K), each pixel is composed of red, green and blue; others are false 4K, such as 4K of RGBW. In order to improve the opening rate, each pixel is composed of red, green, blue and white four colors, and the pixels borrow colors from each other, and then calculate by software. Method realization.
So, choose 4K TV or 4K TV, how to identify? Under the white screen of TV, you can see it with a magnifying glass of 20-30 times.

Thirdly, it depends on the contrast of the display screen.
The higher the contrast, the better the display effect. Compared with ordinary TV, HDR (High Dynamic Range) algorithm is better than ordinary TV. The contrast of HDR TV can reach tens of thousands to one, and the contrast of ordinary TV can reach thousands to one.
Fourth, we need to look at the color gamut of the display screen:
The higher the display gamut, the brighter the picture color, the better the visual perception. The color gamut of LCD display is about 72% of NTSC, while the color gamut of TV with quantum dot backlight can reach more than 90% of NTSC, but the price is also high. This is a trade-off according to their own needs.
If it is OLED (Organic Self-luminescent Display) screen, its display gamut is over 100%, and dynamic contrast is also high. Of course, the price is the most expensive. But in terms of life, it is worse than LCD TV.

Fourth, depending on its IC chip and processor:
For example, there are dual-core processors, quad-core processors, or even higher, the higher the better. Because today's smart TV is based on Android, the stronger the CPU processing power, the better the response speed and display experience.
