As one of the important devices for our home entertainment, TV has always been a must-have home appliance for many families. There are many brands and models of TVs on the market, and the quality is uneven, and how to buy a high-quality TV has become a concern for many families. Today we will talk about the issues that need to be paid attention to when choosing a TV set, and help you choose a satisfactory TV.
First, the picture quality. Picture quality is one of the most important indicators to measure a TV,When selecting, it mainly starts from resolution、Color gamut value、Contrast、Brightness, etc。
1. Resolution.
At present, 4K TV has become popular and has become the mainstream in the market, and even some high-end TVs have reached 8K. However, due to the problem of film source,4KThe needs of daily use can basically meet our daily needs,From the perspective of cost performance,It is not recommended to choose a higher resolution TV in a short time。
2. Color gamut value.
The gamut value is a method of encoding colors, representing the sum of colors that a TV can produce, and the higher the gamut value, the more colors and richer colors the TV can display.
In principle, the higher the standard of color gamut value, the better, and the common color gamut value standards are NTSC, PAL, SRGB, ADOBE RGB and DCI-P3. It should be noted that different color gamut value standards are calculated differently, and do not use different color gamut value standards to compare with each other when comparing. In addition, the color performance of the TV is also related to the tuning of the manufacturer,You can't simply use the color gamut value to measure the quality of the TV。
3. Contrast.
Contrast is the brightness ratio of black and white of the TV picture,The larger the ratio,The more gradient levels from black to white, the richer the color,The TV shows the clarity of the picture、Details、Grayscale, etc. have been greatly improved。
4. Brightness. The brightness of a TV can be divided into two types: peak brightness and average brightness, usually measured in nits. The brighter the TV, the brighter the picture, and in some sunny living rooms, it can also display a clearer and more vivid picture, and when displaying some strong contrast pictures (HDR), it can better present the light and dark effects and rich colors.
If you usually like to play console games and have a need for watching movies, you can choose a TV with high peak brightness.
Second, the screen. At present, TVs are mainly based on LCD LCD, OLED, and Mini LED screens. Among them, LCD LCD screen technology is relatively mature, relatively cheap, and is a common material for many low-end TVs. This kind of screen needs to be backlit to illuminate, and there is basically a leakage of light, which cannot display all black, and the contrast is not high.
OLEDThe screen has the characteristics of self-illumination,And the viewing angle is relatively large,Thinner and lighter、Bright colors,At the same time, the response speed is fast,Usually like to play games、Friends who have high requirements for picture quality can choose this type of TV。
However, the OLED screen is easy to burn the screen, the brightness is relatively low, the life of use is relatively short, and the yield of large-screen TVs is not high, if you mind, you need to choose carefully.
Mini LED is based on the LCD screen, using smaller Mini LED lamp beads as the backlight, and at the same time using a partition to control the backlight. Mini LED screens have high peak brightness, long service life, high definition, good picture level, and relatively low cost, which is very suitable for the development trend of ultra-large screen TVs.
3. Hardware. At present, the TV on the market is dominated by smart TV, and the configuration of the hardware determines the performance and function of the TV. When choosing a smart TV, you need to focus on its processor (CPU) and storage memory, as well as the size of the running memory space.
Among them, the processor of the TV generally chooses the quad-core version,If the performance requirements are relatively high,You can choose quad-coreA73、A55 and other models。
The running memory of the TV is not less than 2G, and the storage memory is not less than 16G, which can basically meet our daily needs.
Fourth, sound quality. Sound quality is also an important criterion for measuring a TV set. When choosing a TV, you can pay attention to whether the TV has stereo effect, Dolby sound, etc. If there is a physical object, you can pay attention to whether the sound of the TV is clear, the volume level, the power of the speakers, etc.
5. Brand. The quality of well-known brand TV products is more guaranteed, and the after-sales service is also more perfect. Among its Chinese-made brands,Hisense TV's picture quality adjustment has always been very good,Hisense's Xinxinu+Super image quality chip simulates the human eye**way,Use algorithms to carry out precise calculations and analysis of the picture,Instantaneous control,Make the displayed picture more delicate、Real。
TCL is the first manufacturer to develop Mini LED screens, so it has strong technical reserves in the field of Mini LED TVs, and it is also one of the few brands with a whole industry chain.
In addition, many TCL TVs do not have boot ads, so if you like large-screen TVs, especially Mini LED TVs, or want to choose TVs without boot ads, you can choose TCL.
In addition to the excellent picture quality tuning, Toshiba TV has a three-dimensional surround effect of its rocket launcher sound system, and you can feel the good sound you have never heard before when you close your eyes, as if you are in the scene, which has always been loved by consumers.
Sony TV is also very good in terms of picture quality adjustment,And its TVs are basically top-of-the-line,With its own PS5 and other game consoles are perfect,It's just more expensive,The cost performance is relatively low。
OLEDTV,You can choose LG and Samsung,These two brands are the world's main OLED screen manufacturers,Its OLED TVs also have a good reputation and sales,It's just relatively high。
The budget is not high, you can also choose Xiaomi, Skyworth, Konka, Changhong and other domestic TV brands, this kind of TV is relatively cost-effective, suitable for families with a low budget.
In addition, when choosing a TV, you also need to pay attention to the system of the TV, domestic TVs are mainly based on the Android operating system, the ecological environment is relatively good, but there are relatively many advertisements.
Sony, Samsung, LG and other imported brands, most of them have their own operating systems, although there are no various annoying ads, but there are fewer applications, you can pay proper attention when choosing, and choose according to your own needs.
