[PConline Talk] “The phrase “I can't go back after I used it†was used in recent years to describe the user’s first experience with a retina screen. Indeed, some product innovations are epoch-making, giving us a whole new experience. On the other hand, if you use it, you don't want to use it anymore. There are actually quite a few products that you can use to detoxify. The same is true for many home appliances. There are products that can be used if you use them. Next, let's take a look at what household appliances are around us that we can't go back to. If we look at what products are used, it is very likely that you will detoxify them. Used to return to the series Can't go back with a big screen TV There is a home appliance. Although you may not use much at ordinary times, it is absolutely indispensable. It is television. What kind of TV is it useless? Large screen TV. Just like the mobile phone, from 2.8 inches to the current 5.7 inches, although the portability of the portable is getting worse, the visual enjoyment is more and more delicate and realistic. People are more willing to talk about portability on the basis of pleasing their eyes. TV has a longer history than mobile phones and experiences greater iteration in terms of size. It can be said that it is the most important carrier for the development of display technologies. Why can't the big screen TV go back? Because the trend of large-screen and display technology advances hand in hand, because the big screen brings the immersive feeling, just like the fiery VR now, is not a 360-degree panoramic 3D screen display effect? I remember when I was a child, the first black-and-white TV in the house was 12-inch, and it was still stored in a warehouse. It was no longer possible to boot. If this 12-inch TV is also 4K, all the picture quality effects are exactly the same as the current LCD TVs. Can you give up the current TV at home to see this 12-inch TV? Can't go back at all. Although that 12-inch TV has brought you a strong sense of freshness, curiosity, and satisfaction. Once you are exposed to a larger screen and experience a more immersive experience, who will go to watch the TV with the size of a tablet computer? One phenomenon is particularly interesting. Every time I go to the store, there will always be a reference to the size of a living room to buy a TV. However, I wonder if you have noticed that there will be a new version of this distance dimension table almost every two years or so. In 2008 your living room is suitable for 32 baht, 11-year for 42 baht, 13 years for 50 baht, 15 years for 55 baht, 16 years for 65 baht. Obviously your living room doesn't get bigger, but every year you subvert data from the previous year. It is very gratifying for more and more people to understand this truth. The TV is "not too big" and the big-screen TV really can't go back. Because the sensation of telepresence brought by the large-size viewing equipment can be more profound than the physical resolution, color, and dynamic quality. The simplest example is a movie theater. Every time I watch 3D blockbusters, I like to sit in the third row. The big screen will not give you a sense of depression. It will only make you more excited. The American Film and Television Engineering Association has a movie theater to see reference data for distance and perspective. First, let the screen fill in as much of the viewer's field of vision as possible. The viewer’s perspective in the horizontal direction should be at least 36°. Second, to avoid fatigue on the viewer’s neck, the angle to the horizon must be less than 35°. A simple calculation can be made. If your living room is 4.5 meters deep, how much screen will be needed to have a cinema effect? The screen needs to be 12.3m long. I estimate that the whole wall of your living room is not big enough for the screen. At the CES at the beginning of the year, major TV manufacturers, including domestic ones, made appearances of 98-inch televisions. With the continuous maturity of LCD technology, the cost of large-screen TVs is continuously decreasing. This year, 65å‹ has become the mainstream large-screen TV, and the price has dropped to around 10,000 yuan. There are also ultra-short-focus laser projection technology is also constantly making efforts to give consumers more choices for large-size viewing equipment. Of course, the aforementioned distance and size are not without reference value, but it should also take into account the resolution factor, as well as eye health. Anyway, if you use a big-screen TV, you can't go back to the small screen. If you say "TV is not as big as possible," I guess it should be that you buy a small one. Sonic toothbrush, no longer want to use manual To put it plainly, when I first came into contact with an electric toothbrush, I took a wait-and-see attitude on the conclusion that “the cleaning effect of electric toothbrushes can throw a manual toothbrush a few streets awayâ€. However, a few months have passed and one of my hands has passed. The sonic vibrating toothbrush with less than four hundred oceans made me unable to return to the past era of hand brush. Of course, if you want to say that the effect is particularly obvious, years of dirt in the teeth (as shown in the picture below) will be brighter and brighter if you brush two or three times. And I can say very responsibly that you are not clean for a month. The dirt accumulated in more than a decade or two can be cleaned with a few electric toothbrushes. I think you are afraid that there are no special chemical substances inside. However, it must be said objectively that the electric toothbrush (I use a sonic toothbrush) has a more thorough cleaning effect on plaque than a manual toothbrush. When brushing teeth with a manual toothbrush, if we use a fingernail to pick up the tooth surface, especially the first and second teeth in the teeth, we will find that even if we brush our teeth very seriously, we can still get a lot of white particles. However, if a manual toothbrush is used, the amount of white particles extracted is relatively small, and as the electric toothbrush is used skillfully, fewer and fewer white particles will be found. Perhaps this is why I could not go back. What is the most important summer? air conditioning? Before writing a small article on air-conditioning disease, the comment area had a netizen reply that: My life is air-conditioning. Of course, this statement is a bit of humour and humor, which also shows how important air conditioning is in the summer. No matter if it is a car ride, an indoor office or a shopping mall, we can't live without air conditioning. For people who are accustomed to the air-conditioning environment, it is absolutely difficult to adapt to the unconditioned indoor environment in hot summer days. And now the price of air-conditioning is very close to the people, the price of one thousand five up and down can buy a big new air-conditioning, buy air-conditioning to enjoy the cool summer is not difficult for most people. All in all, when you get used to the air conditioning, you can't go back. No amount of fans can match the cold air of an air conditioner. What we need to do is to use air conditioners scientifically and healthily, and be ready to deal with the frequent use of air conditioners in summer. Rising electricity bills. Men's Must Have Products - Shavers For men, in order to maintain their own good image, there is always a razor in everyday life. And an electric razor is an artifact in the eyes of men. Whether traveling for business or working at ordinary times, using an electric razor can save time and worry. Electric razors can be mainly divided into rotating and reciprocating, mainstream products are basically equipped with a three-head, there are some reciprocating new products are updated into the five-head era. Compared with manual razors, in addition to excellent shavering capabilities, electric razors have the advantage of ease of use, and most products support dry and wet shave, as long as the machine has sufficient power, the user is ready to pick up anytime, anywhere . In addition, some electric razors are equipped with a face brush and a bristle trimmer to form a complete personal vision system, which is not available in manual razors. With a series of detoxification Home mini ice cream machine Nowadays people are pursuing health, even desserts, and occasionally they like to do it themselves. However, many times this type of appliance may not be used once or twice and will remain in the corner forever. According to my personal experience, an ice cream machine is such an electric appliance. More than a year ago, I came into contact with an ice cream machine that can make almost the same amount of ice cream as KFC ice cream cones at one time, about 200 ml, and it takes 1-2 hours. Have to say, compared to the use of refrigerators to make ice cream, the effect of this ice cream machine is simply too high, and the ice cream from the refrigerator is not as soft and solid as the ice cream machine. But personally, I don't mean that people have this need. First of all, if it is a home ice cream machine, the general capacity is not, if only 1-2 small partners, it can still taste fresh, but if it is three or five people, it is estimated that it is more practical to buy a few sheep downstairs. After all, the single-stirring process takes 90 minutes. If it is a little time consuming to entertain a wave of buddies, perhaps it will start stirring and stirring the night before. And if you just want to try your hand at crafting desserts, personally feel that it is better to go directly to the shops that have this kind of handmade cakes. Not only the machines are complete, but there are also special masters who are instructing them to compare with their own at home. The more practical, do not have to worry about the machine used once or twice to accompany the dust. Air-conditioning fan - a beautiful fantasy On a hot summer day, almost everyone wants to stay in an air-conditioned room all day. In the absence of air-conditioning, the fan may become another choice for many people. However, on hot days, the wind blown by the fan is likely to be hot. So what to do? Many manufacturers have given an answer: that is, the air-conditioning fan, and at the same time it can become a cooling fan. This fan, which claims to be able to blow out cold wind, can be purchased at a price of only 200 yuan, and can be purchased at such a low price. An air-conditioned fan that allows you to enjoy the cool air? Xiao Bian can only say that this is just a beautiful illusion. In fact, almost all air-conditioning fans on the market need to use ice crystals to cool the water in the air-conditioning fan's internal water tank. Ice crystals need to be put into the freezer of the refrigerator for refrigeration to work. This step seems to be tedious. Another point is that the internal water tank of the air-conditioning fan is likely to accumulate some dust, and even some of it may not be known. It is not very hygienic to use. In addition, the general air-conditioning fan noise is not small, the fan in the box, the noise generated is naturally larger than the average fan, and the cold wind blowing out will have a wet and wet feeling, close to the body, the human body The feeling is not comfortable. In general, products such as air-conditioning fans can indeed bring cold winds, but they are not the kind of cold wind of air conditioners, and the noise is relatively large. As a user who bought air-conditioner fans, Xiao Bian felt that it would be better to use the money to buy air-conditioner fans. Buy the reality of the two floor fans. Coffee machine - lazy certainly does not apply For some people who are pursuing exquisite lifestyle, grinding a cup of delicious coffee is indeed a good choice. But for most people, the coffee machine is a home appliance that you don't want to use again. The reason is too much trouble! The coffee that is ground out using a coffee machine does indeed have a certain degree of authenticity, but it is very troublesome to wash the coffee residue after each coffee cooking. If it is not cleaned up in time, the coffee bean residue attached to the machine will dry out. Over time, It will be more difficult to clean up. Therefore, in order to facilitate the picture, many people will still choose to drink instant coffee, coffee machine has become a decoration, if the daily coffee consumption is very small, there is no need to buy a coffee machine. Ordinary domestic mosquito killer How to deal with mosquitoes at home? You may think of using mosquito nets, mosquito coils and other methods, and the mosquito killer may be a magical existence. I believe many people have bought insect killer lamps, but in the end they did not catch many mosquitoes. Xiao Bian wants to say that in fact, the mosquito-killing lamp has relatively high requirements on the use environment. First, it should be placed at the corresponding height (.05-1 meter height), and then the mosquito-killing lamp must be turned on in a completely dark environment. Let the mosquitoes identify the presence of the mosquito killer. Finally, if the wind in the environment flows too much, instead of the static wind environment, the efficacy of the mosquito killer will be greatly reduced. In view of the above several conditions of use, in fact, the general family environment, buy a mosquito lamp and can not grasp the text is also normal, after all, when you turn on the air, the indoor wind is also kept flowing, the fan is even more The air in the room will be agitated, and it is almost impossible to use the mosquito killer in a relatively static indoor environment. Therefore, the mosquito killer can also be regarded as a kind of electric appliance that Xiao Bian used to have no expectation for it. It is usually placed at home as a lighting night light. It is too light for it, when the mosquito killer lamp, it is too Not too many mosquitoes, so in the end it was only to eat ash. Summary: The products that have been used to return users are better experience and a sense of dependence. When used products that are likely to be detoxified, it is not that the product itself is necessarily bad, but may be It is suitable for use by the general public, and it is not so well-publicized and the product still needs to be improved. What else do you think that you feel like using a home appliance that you can't go back to, or use a detoxification product?
