Three factors to pay attention to when buying LED TVs

The three most easily overlooked factors when purchasing LED TVs.

1. Picture refresh rate

Speaking of picture refresh rate, many friends may feel unfamiliar, but many friends must be familiar with terms such as 50hz. Now, the picture refresh rate of most TVs is about 50hz, that is, it is displayed 50 times in one second. To put it another way, the picture refresh rate of 50hz means that 50 pictures are displayed one by one in one second on average, and the display time of each picture is 1/50 second. This speed is already very fast, but the human eye can still feel that the picture is flickering.

If it is displayed 100 times in one second, its refresh rate is 100HZ. Conversely, 100 pictures are displayed one by one in one second on average, and the display time of each picture is 1/100 second. Compared with the human eye, it will feel that this picture is like a picture, very "fixed", not flashing all the time. In fact, this picture is also flashing all the time, but it flashes faster and people can't notice it.

That is to say, the higher the refresh rate of the LED TV, the better the restoration effect of its high-speed dynamic picture, and the better the protection of human eyes.

2. Network performance

It is now the Internet age, and this year is also the time when the concept of "Internet TV" is very popular. Leading technology has made a qualitative leap in the picture quality of LED TVs, and many users hope to have some computer functions through LED TVs. As we all know, people can only operate TVs through remote controls. If LED TVs have excellent network performance, they will definitely be sought after by users. The network functions of many LED TVs on the market are average, and they can only download videos from the Internet through TV.

3. High Definition

Many consumers buy LED TVs for "high definition". But looking around, how many LED TVs are high definition? Real high definition must at least support 1080P full high definition picture quality, and it must be hard high definition, not high definition achieved through software. The author believes that Samsung's 8000 series and Skyworth's Coocaa series are both full high definition products. The distinction between true and false high definition is first through film testing, and then by looking at its technical indicators.

Although the price of LED TVs has been falling again and again, they are still a luxury for the working class. Therefore, it is recommended that consumers should not ignore the three factors of picture refresh rate, network performance and high definition when buying LED TVs.
