The smart TV industry has won the second spring and has gradually embarked on an unstoppable development path from the trough. In the existing market, there are a large number of color TV brands, and the number of major models is numerous. It is really difficult for ordinary consumers to buy a suitable TV from China. In fact, when we purchase large-screen high-definition televisions, in addition to factors such as brands and technology applications, TV picture quality is also a key point to measure the quality of a TV. So, how to choose a large-screen smart TV, the four buying techniques can not be ignored.
First, 4K universal resolution is better
Resolution This parameter has a very important meaning for the display device. In the case of the screen size of the same size, the higher the resolution is, the finer the screen is, that is, the details of the screen can be displayed more clearly, which greatly increases the user's vision. Experience.
Currently there are three main resolutions of TVs on the market: 1080P, 2K and 4K. 4K TV has experienced the development of recent years, with its high-definition natural and realistic picture display effect has become the first choice for consumers to buy TV. However, consumers need to pay attention to what matters should be paid attention to in the process of buying 4K TV? The first product to be purchased must have a physical resolution of 38,402,160 and a pixel size of 8,294,400. Only such a product can be rated as a truly qualified 4K super. HDTV. There is a 4K TV in the original RGB three primary colors based on the addition of white pixels, but lead to each complete pixel volume is too large, horizontal resolution from 4K attenuation to 3K, can not achieve real 4K display, in fact, only 6 million pixels display effect, so As a result, it will inevitably cause a certain degree of damage to the quality of television.
Second, a good picture quality must have a good backlight
The display effect of LCD TVs is mainly determined by the screen, backlight module and image processing technology. Since the liquid crystal itself does not emit light, it needs to be illuminated by the backlight to be seen by the human eye. Therefore, a good quality backlight technology plays a crucial role in the picture quality of the liquid crystal television.
Hisense is a relatively good brand of backlight technology in the industry. Its self-developed ULED TV can achieve backlight partition control. ULED divides the backlight of the LCD TV into several independent control units. Each unit can accurately adjust the backlight opening and closing of the corresponding area according to the distribution of bright and dark fields of the TV screen, and can perform peak adjustment of the backlight brightness. Rich image hierarchy and outstanding depth of field. The authoritative detection by the China Electronics Standardization Institute, ULED TV dynamic contrast ratio reached 8 million: 1, compared to ordinary 4K TV increased 3 orders of magnitude, more detailed performance.
Third, the shorter the response time, the better the picture does not end up
Due to the lack of response time, the liquid crystal panel has a certain amount of tailing and jitter. When high-speed images are displayed, especially in fast-moving images such as sports games and action movies, the trailing and ghosting phenomenon also comes along. Phenomenon not only seriously affects our viewing effect, but it also causes visual fatigue and dizziness. Therefore, a smooth television picture will undoubtedly become another important indicator to measure the quality of TV pictures.
Since the birth of LCD TVs, major TV manufacturers have been working hard to resolve the tailing phenomenon. The response time was shortened from the original by reducing the thickness of the liquid crystal panel, and then the response speed was increased by increasing the driving voltage. Afterwards, in recent years, the commonly used MEMC anti-shaking technology, each solution alleviates the tailing to some extent. At the same time, it brought new problems.
In addition to UMEM anti-shake technology, ULED TV also uses a high-speed scanning system up to 1440Hz, which makes the liquid crystal in the state of the backlight blackfield scanning during the rotation, to improve the smearing caused by the lack of response to the liquid crystal, reducing the image residue of the human eye Feelings to achieve a smooth motion picture. After the end of the movie, there are no dazzling ending titles, and the meteor-like F1 car will not drag long tails.
Fourth, look at the color performance The larger the display range, the better
Color performance is another important factor affecting the picture quality of TV. Due to the limitations of display technology, even 4K TVs cannot fully represent the ideal color number of 1.07 billion colors. At present, the color gamut display range of most 4K TVs is between 72% and 85%. ULED uses blue chips to excite red and green phosphors or quantum dots, and optimizes thousands of sets of experimental data to design the best color filters and high-gamut LED backlight spectra, which can present more color details. The ULED color gamut display range can reach 120% of the BT.709 HDTV color gamut standard.
