The so-called "scarring flowers are fascinating eyes", "I don't understand, this world is changing fast"... Since the flat-panel TV entered the LED era, the frequency of TV technology has been greatly accelerated, and many are unfamiliar with flat-panel TVs. Consumers are also stunned by the various terms and concepts that are flooding the market. In order to help consumers understand the products, we especially listed several important parameters and concepts common to the mainstream flat-panel TVs on the market, so that the majority of netizens can have a simple understanding and not be fooled.
LED TV
The concept of "LED TV" is actually not new anymore. The reason why it is to be taken out this time is because the name itself is a mistake. Strictly speaking, "LED TV" should be called "flat-panel TV with LED backlight". In the original (LCD) flat-panel TV technology, the backlight was replaced with an LED light source, which was more energy-efficient and lighter, and was not optimized for image quality.
The so-called "LED TV", because it has long been a universally popular technology, so if you want to buy a flat-panel TV is not "LED TV", then still wash and sleep.
3D TV
In fact, 3D technology seems to have gradually withdrawn from the mainstream technology of flat-panel TVs. At present, major TV manufacturers are no longer focusing on the part of 3D video playback when new products are launched, and even some new products have no longer supported 3D video. The situation is mainly due to the fact that the actual experience of 3D video on TV has not achieved the desired effect.
Of course, although many manufacturers no longer promote 3D video playback, it is still the standard feature of most mainstream TVs at this stage. If you still want to try it out occasionally, you can pay special attention to it.
Smart TV
Smart TV is the mainstream TV technology nowadays, and the comprehensive intelligence of flat-panel TVs is already an unstoppable trend. Smart TV uses a smart operating system, which can install applications, games, online video resources, and some even support voice control and gesture control.
At present, the intelligent systems of mainstream TVs are roughly divided into Android systems based on domestic brands and self-owned systems based on foreign brands (such as Tizen system and webOS system). It should be noted here that many domestic TVs have made deep customization of the system, but in the end they are all based on Android.
The advantage of the Android system is that the related applications are large, and many applications can directly transplant and optimize the Android mobile phone application into a TV application, which greatly improves the playability of the Android smart TV. The self-owned system of foreign brands, because most of them use closed systems, have more advantages in terms of system security, basically do not have to worry about the possible problems of smart TV viruses in the future, and at the same time, seamlessly connect with other products of the same brand. It's also easier.
4K Ultra HD TV
4K Ultra HD TV, in the simplest terms, is a TV with a screen resolution of 3840*2160 pixels. This is a hard indicator. When Full HD was not popular, all the big stores were “1080i†and “ The 1080P" sign doesn't know how many consumers are confused. Fortunately, from the full HD resolution of 1920*1080 pixels to the ultra-HD resolution of 3840*2160 pixels, there is no more "2160i" on the market. And so on.
