Double 11 is a good time to buy television, especially at the beginning of the year due to rising raw material prices, the television industry experienced a wave of price fluctuations, and with the gradual decline of raw material prices upstream, a big wave of promotions in the upcoming dual 11 is about to begin. In general, the price of TV is getting cheaper nowadays. However, many users suddenly become confused when they purchase a TV. The following is a quick look at what parameters to buy TV.
1, picture quality
In the first place, of course, the picture quality, the most important thing to buy TV is certainly the quality of performance, but now many television brands do not pay enough attention to the quality of the picture, and even evade the light, the main energy used to promote some flashy things, such as How thin the body, the content is twice as much as the opponent, it can be said that the cart before the horse.
The parameters related to image quality include color gamut, HDR, and the like. The color gamut is the range of colors that can be represented by the range of colors. The following horseshoe type chromaticity diagram may not be unfamiliar to you. It was proposed by the CIE International Committee of Illumination in 1931. The horseshoe-shaped area is the visible range of color gamut. The range of color gamut that each TV can represent is represented by a triangular area consisting of RGB three-point lines. The larger the area of ​​the triangle, the larger the range of color gamut.
CIE1931 Chromaticity Diagram
Sharp has no ** wide color gamut technology
The color gamut value of ordinary LCD TVs is generally about 74%, while the wide color gamut TV can reach about 90%, and Sharp's non-gaming wide color gamut technology can reach 105% (CIE1931 standard), due to the use of KSF fluorescent crystals. And color filter technology to enhance the purity of the backlight, improve color gamut coverage while avoiding ** pollution, so that health and environmental protection. The higher the color gamut means that the TV can display richer colors, the screen is not only bright and more realistic, although the wide color gamut and can not directly represent a good picture quality, but the television with good picture quality must have a high color gamut coverage.
Let's take a look at the HDRs that have been hot for the past two years. HDR is an abbreviation of High-Dynamic Range. It was first applied in the field of photography. It is mainly used to display rich and dark information on television. However, HDR is not a technology but a collective expression of display effects. Before it appeared, in order to achieve the HDR effect, some television manufacturers have achieved significant results in this area, such as Sharp TV technology.
HDR enhances brightness and darkness
An important component of Sharp's color technology is the partitioned backlight control, which can intelligently analyze the image and adjust the brightness of the backlight in different partitions to reduce the brightness of the backlight in the dark, brighten the backlight in the bright part, and further enhance the screen. Contrast, there is also a great magic weapon in another color technology - brightness signal detection technology, Sharp's unique algorithm will intelligently calculate which part of each element in the screen should be brighter, which part should be darker, combined with backlight control technology, highlights The light is controlled separately from the dark part, so that the light and dark contrast is more prominent.
Although there are more and more HDR TVs now, most HDR TVs will only be effective when playing HDR sources. Sharp's color technology is implemented through backlight control and signal source analysis. Needs the support of the film source, can show the HDR effect in playing any video format, this kind of picture quality technology of course has more realistic significance.
Sharp exclusive color technology
Take Sharp's just-released 8K TV, 216 control divisions and 1000 nits of peak brightness provide the hardware basis for the presentation of HDR effects. Not only can the highlight details be displayed well, but black areas can be even darker. Moreover, Sharp's color technology can also compensate for backlighting over the dark and light areas. When performing some overshadowing images, the connection will be more natural and soft.
2, sound quality
The sound quality is also very important for TVs. However, nowadays TVs are getting thinner and thinner, and the sound quality is even worse than the early CRT TVs. Although the content is more and more abundant, the sound is dry and powerless. It affects the overall viewing experience. In fact, it is pursuing. There is no complete contradiction between the slim design and good sound quality.
Sharp despises the S60's integrated Soundbar design
Sharp's previously released S60/S60U series TVs have a good sound quality while maintaining a slim design. For example, the S60 is a one-piece design. The Soundbar on the bottom is cleverly integrated with the pedestal. Two treble units + 2 midrange units are sounded forward, and 4 woofer units have a total of 20W power output to make bass deep enough to deepen the sound. The sense is stronger, and the same is true for the split-design S60U.
3, hardware configuration
Because the smart TV is equipped with an operating system, the hardware configuration has to keep up, just as when we were buying a mobile phone, we must buy those with high configuration, so that we can use it to be smooth and non-stopping. Judging the level of a TV hardware configuration mainly depends on the processor, memory, flash memory and other parameters, of which the combination of 2GB memory + 16GB flash memory is relatively common, at least 3-4 years is enough, and there are also stronger, such as Sharp The 8K TV is not only equipped with 64-bit chips, but also uses 5GB of memory and 64GB of flash memory, fully taking into account the needs of the 8K era.
4, appearance process
The progress of science and technology in television has been markedly improved. The borders, bases and other parts are basically made of metal materials. After anodizing, drilling and cutting processes are of great grades, and even the back design is very elegant, not hesitating to use metal. Materials, drawing process, etc., are getting higher and higher. In addition, the design trend of full-screen is now very popular, not only in the mobile phone industry, "full-screen" TV because it reduces the constraints of the border, when watching TV can bring good results.
Sharp despises S60 frame only 1.6mm
At present, many televisions have ultra-narrow frame design as a selling point. How thin is it? Not clearly labeled, and sharp before the release of Sharp S60 series of borders only 1.6mm, which is the thickness of a five-cornered coin, when watching TV is basically no longer bound by the frame, this can enhance the visual enjoyment of the limit process more Worthy of respect.
The above are four aspects that should be paid attention to when buying a TV now. In particular, attention should be paid to the picture quality because it can directly reflect the technical strength of a TV, such as the Sharp color technology mentioned above, and it is of excellent picture quality. TVs are generally more sophisticated in terms of sound quality, hardware configuration, and appearance. If you want to buy TV on the upcoming Double 11s, you must be more rational about all kinds of publicity terms. Don't be biased.
