Will understand this, you will decide what TV to buy it

TV sets use live methods to deliver live visual images in real time. Similar to a movie, TV uses the visual residual effect of the human eye to present a frame-graded still image to form a visually active image. The transmitting end of the television system converts the fine parts of the scene in terms of luminance and chrominance into electrical signals and then transmits them sequentially. At the receiving end, the brightness and chromaticity of the fine parts are visualized at the corresponding geometric positions to reproduce the entire original image. To know that TV is also a shopping skill when buying, how to buy a TV, but related to the feelings of watching TV, you can not choose to regret it. Because the types, models and brands of televisions are constantly increasing, how to buy TVs has also become one of the biggest headaches for people. Now I will teach you how to buy TVs and TVs.



How to buy a TV

When shopping for TVs, you need to pay attention to many aspects. At the same time, you should pay attention to the contrast between TVs of different models and brands. Just like we buy mobile phones, we compare various brands and models of mobile phones and select ourselves. Like phone. How do we buy a TV when we buy a TV? Now let's take a look at the specifics.

1, clarity

The clarity of the TV is the most important issue that we need to pay attention to when buying a TV, and it is also a problem people are most concerned about. The resolution of the TV is also the resolution of the TV. The higher the resolution, the clearer the TV screen. The resolution of the LCD TV is generally 800×600, 1280×768, and 1366×768. However, the 4K TV now has a resolution that is four times higher than the resolution of LCD TVs. It is now the highest TV resolution TV set.

2, screen quality

The quality of the TV is also a concern for people choosing a TV. The high-definition of the LCD TV is its advantage, but at some times when using a LCD TV to watch a movie, we can find the LCD under high-speed dynamics. There are tailings on TV, but plasma TVs have advantages over LCD TVs.

3, the speed of response

The response speed of LCD TVs can be regarded as a weakness of LCD TVs compared with plasma TVs. Plasma TVs respond faster than LCD TVs. The faster the response speed, the less the TV will appear to be trailing. LCD TVs The phenomenon of tailing on the screen is also caused by the relatively slow response speed of the LCD TV.

4, size

The size of the TV is determined by the size of the room. The larger the TV screen, the better the viewing distance is when watching TV. If the room is too small, the size of the TV is very large and it is easy to oppress the user's eyes during the viewing process. Damage to the user's eyes, so the choice of LCD TV size also need to be determined according to the actual situation of the room.

5, brightness selection

How to buy a TV, in fact, the brightness of the TV is also an important factor in our selection of TV. The brightness of the TV is too low. When we watch some dim scenes, it will show no effect. At the same time, the brightness of the TV is too low, which will affect the clarity of the TV and the quality of the picture. However, this does not mean that the brighter the TV is, the better. The excessive brightness of the TV will burn people's eyes. Therefore, when purchasing a TV, it is necessary to observe whether the brightness of the TV is even.

6, color selection

The choice of television colors is also a focus of our attention on how to choose a TV. The choice of the color of the television is not to let everyone choose the color of the TV appearance, but the color of the TV screen. Now the TV closest to the natural color is a better one. The color of this TV is even more restored. People also It's easier to accept, true to restore the true nature of the object, and the user's viewing experience will be more realistic.




TV shopping tips

First, depending on people, close to reality

The main emphasis here is to see who you want to buy a TV set for. Different users choose different TV sets and they must be allocated according to the actual situation.

1. Buy for older elders

Buying them actually does not have to pursue any brands and functions. The TVs they need are simple and easy to use. Such TVs are their favorite. You can buy a Samsung's latest smart TV may not satisfy them because they It will not be used at all. For them, ordinary liquid crystal is the best choice, according to home to pick a suitable size, choose a similar brand on the line. Because they are not too harsh on the effect, so the domestic brands have been fully qualified, after all, they just get to watch cable TV, see "My Fair Princess" it is necessary to spend 20,000 to buy Sony?

Young people buy after 2.80 and 90

Young people generally prefer brands, some people talk about TV is Nissan, some people have to talk about television, they must have joint ventures, and some people like to use the same brand of things, so for the young people, Brands are often more important than features. In this way, some big brands are selected and they have more functions, such as sensor games, network television, and the like. But in fact, Xiao Bian really does not recommend buying online TV, you will find that they really have no use, it is better to go directly to the computer.

Second, TV size selection

How to buy TV size? The viewing distance of the recommended television is generally about 3 times of the diagonal size of the television. Recommended reference: straight line distance within three meters, the room size is less than 20 square meters, choose 25-29 inches; straight line distance of about three meters, the room size is 20 to 30 square meters, choose 29-34 inches; about four meters The straight-line distance, room size is 30 to 40 square meters, select 35-43 inches; linear distance more than four meters, the room size is more than 50 square meters, select the LCD TV more than 43 inches. Entering the era of flat-panel TVs, 42-inch LCD TVs and plasmas have gradually become a watershed, the size of the plasma TV is basically the smallest 42-inch, 42-inch or less almost become the camp of LCD TVs. Of course, LCD TVs have more than 42 large-screen TVs, but the price is relatively much higher. If the budget is sufficient, you may consider buying LCD TVs. However, if you want to buy more than 50 inches and have a higher cost performance, then Still choose plasma TV is more appropriate. Today's flat-panel TVs are all widescreen 16:9, and the TV signal is still 4:3, so use the ratio of 16:9 to put a horizontal stretch, used to be just fine, you can also adjust to 4: 3, but there are black borders on both sides of the screen.

Third, the TV should be clear enough

No matter what TV, in general, the first point is of course the picture quality. Only the TV with good picture quality is the first choice. When viewing TV picture quality, it requires a clearer picture, wider color gamut coverage, and color reproduction. Higher, but now the so-called LED TV on the market is only "LED backlight LCD TV" only, its picture quality is not necessarily better, so we must carefully choose.

When viewing the definition of the LED TV screen, the same high-definition signal can be connected to the LED TV and the LCD TV at the same time. If the resolution of the LED TV is not as good as that of the LCD TV, it proves that this LED TV has a false name; cut off the signal connection and check the blue screen status. Under the LED TV, the four corners and the central part of the brightness is even or there is no light leakage around the phenomenon, if uneven or there is light leakage, are not optional.




In addition, the uniformity of brightness is also very important. However, this indicator is usually not marked in the LCD TV product specification. The only way to check whether the brightness is uniform is through careful observation. When the screen is a single color, it is most conducive to observation. When selecting the screen, adjust the screen to red, green, and blue, respectively, and check whether the brightness of the screen is even at 2.5 meters.

Fourth, television energy consumption needs to be considered

From the perspective of energy saving, LCD TVs are the most ideal, and their power consumption is rarely more than 200W. In spite of this, it is still necessary to choose brands and models with low power consumption. Because the size of power consumption directly affects the life of the screen, and the power consumption is large, it not only consumes electricity, but also speeds up the aging of the lamp. After a long time, the screen will turn yellow and darken.

Editor's summary: The above is the professional Weapon: how to buy the most value-added TV is the king's relevant introduction, how to buy TV we should also pay attention to some issues, such as whether with HDMI interface, pay attention to the actual resolution , pay attention to brightness, contrast, viewing angle; pay attention to the reaction time, dead pixels and bright spots. Check whether the LCD TV has bright spots, the easiest way is to make the screen all black, about 30 cm away from the LCD TV screen, see if there is a bright spot in a black. Then let the screen white and see if there is any dead pixels.


Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.

Conventional enzyme production is mainly produced by hand, hand-sliced, hand-fermentation, the company every step of the process are used self-developed technology and equipment to automate production. Moreover, the conventional enzyme production have adopted a fermentation technology, enzyme often taste discomfort, sour and other issues, I produced using a variety of enzymes, probiotics composite grade fermentation technology, fermentation at different times with different strains, and two or three times through fermentation, enzymes such pure taste, streptozotocin balanced nutrients. Scientific and standardized process:

I produced using enzymes navel cleaning, sterilization, slice, fermentation (fermentation grade composite multi-strain), solid-liquid separation, bottling and other steps. Each step developed a patented automated production equipment, fully automated production, to avoid the traditional manual production workers are not standardized, easy to pollution, low production efficiency, product quality is unstable defects.

Companies registered capital of 35 million yuan, the end of 2014 the total assets of 48.69 million yuan, including fixed assets of 37.52 million yuan. The company's existing cooperation Orange cultivation base 7043.5 acres, the company production base is located in Jiangxi County Tech Industrial Park Chu Tan industrial area, covers an area of 120 acres, it has built a standard plant 9,000 square meters, Nissan 6000 kg Orange enzymes and other liquid enzyme products. Enzyme, known as enzyme, refers to a polymer substance having biocatalytic functionality. In the catalytic reaction system an enzyme, the reactant molecules are known as substrates, enzyme substrates by catalytic conversion to another molecule. Almost all cellular activity of enzymes involved in the process are required to improve efficiency. Similar to other non-biological catalysts, enzymes chemical reactions by lowering the activation energy to accelerate the rate of the reaction, most of the enzyme catalyzed reaction rate can be increased a million times; in fact, the enzyme is to provide an activation energy needs than another low way, so that more particles to have less than the activation energy of the reaction kinetic energy, thus speeding up the reaction rate. Enzyme as a catalyst, in itself is not consumed during the reaction, it does not affect the chemical equilibrium reactions. Positive enzyme catalysis, but also a negative catalytic effect, not only to accelerate the reaction rate, but also to reduce the reaction rate. And other non-living catalysts is different, having a high degree of specificity of enzyme, only a catalytic reaction or produce a particular specific configuration.
