What is a Big Screen Led Tv
Today, LCD TVs with LED backlight gained well-deserved popularity among buyers. These devices use the cutting-edge video technologies and have a great functionality compared with their predecessors, such as Internet connection feature and the capability to view the video content in on-line mode. For using these features, you will need a cable Internet connection or a Wi-Fi Internet connection. With the first option widely available nowadays, for using a wireless connection you will need a Wi-Fi router.
Modern LED TVs consume little power, thus saving your money. LED TVs also have a reduced thickness and weight design compared with the plasma TVs. Still, the most important benefits of these TVs are the natural color reproduction and higher image rendering quality. LED backlight provides the high dynamic contrast ratio and allows the application of zone lighting of the screen. So what are the main points one should take note of when choosing among several models? In today's review, we'll try to highlight the key LED TV features to consider when buying an LED TV.
What Features to Compare
The most important criterion when choosing any LED TV is its Video picture parameters. In the first place, we need to determine the TV screen size (diagonal). One should choose the diagonal of an LED TV (available options range between 10" to 90") based on the size of the room, in which it will be located. Owing to the more up-to-date and advanced LED-backlighting technology the offered LED TV screen sizes today are bigger than those of plasma TVs. The next point calls for considering the type of the panel used. Currently, there are 3 main types of flat screen TV panels: IPS, S-PVA, UV²A. IPS panels offer the largest viewing angles. S-PVA panels provide a higher black level, and the UV²A panels combine the advantages of the two previous types, which makes them best suited for the high-end TVs. UV²A panels are manufactured by Sharp. Talking about the panel resolution, we should note that it is characterized by the number of panel active components, pixels (dots), horizontally and vertically. The higher the screen resolution, the more details and the better overall quality the picture will be rendered at when playing files from a variety of electronic media, as well as from the television signal source. The high panel resolution is especially beneficial for the digital TV signal such as the one provided by HDTV and UHDTV broadcast standards.
The last parameter, which directly affecting video picture parameters of an LED TV, is the panel refresh rate, which in turn is determined by the response time of each pixel. The higher the frame refresh rate, the faster the image is updated on the screen of an LED TV and the smoother and more natural the motion looks (IPS-panels have a relatively big response time). Despite the high specified refresh rate values by many manufacturers (up to 1200 Hz), the actual refresh rate ranges from 50 Hz to 120 Hz, while the higher numbers are obtained using specific measurement methods, various marketing "tricks" (refresh rate of some specific area of the screen, etc.) and proprietary technologies. It should be kept in mind that the human eye cannot tell the difference between the screen refresh rates of an LED TV starting from 100 Hz and higher.
The next important feature to consider when choosing an LED TV is its Functionality. Smart TV feature, for example, makes it possible to connect our flat screen TV to the Internet and use a browser, interactive applications, online movie theaters and other integrated services. This requires the availability of an Internet connection. LED TVs may be equipped with a wired Ethernet connection and a wireless Wi-Fi connection. The best option is to have both these types simultaneously. A built-in processor (CPU) of a TV is utilized for loading the applications and surfing the Internet, thus, the more powerful this processor is the better the user experience is. Some TVs have multi-core CPUs with 4 or even 8 cores. There are also TVs that support the function of the 3D-image display. These LED-TVs support a particular 3D video format that can be transmitted using the three methods: side-by-side, over-under, or full side-by-side encoding. Functionality also determines the possibility of connecting various external devices (via the USB-ports, the SD-card ports, video and audio interfaces - HDMI, DVI, etc.) in addition to receiving the broadcast TV signal.
The last important parameter, which should be pointed out, is the TV Sound quality. The quality of sound reproduction can be estimated by many different parameters, but in practice, manufacturers prefer to limit the specifications of this feature with the output power of the built-in speakers and the number of the speakers. Most modern TVs come with built-in audio hardware decoder that supports multi-channel audio playback (up to 8 channels) (mainly - DTS or Dolby Digital audio streams). The availability of a built-in decoder and speakers not only allows you to watch your favorite movies enjoying the multi-channel audio support but also simply listen to music.
