Is the TV a must have appliance in the home?

I think the TV is a must-have appliance in the home, and the main reasons why I think so are the following reasons:

The first aspect is that televisions are highly used appliances. With the development of science and technology, more and more different kinds of televisions have been invented, flat screen televisions, LCD televisions.

There is also a projection screen**, the invention of this kind of item is to give people relaxation and entertainment. At the end of a tiring day's work, people can watch TV to relax, take a break, and relieve fatigue, and now there are many hilarious comedies that can make people laugh, which is also a great form of entertainment. That's the first reason why I feel like a must-have TV in my family.

The second aspect is that TV will make the home scene look richer. TV is a big household appliance,It will make the family scene look more things when placed in the home,And the items will not be very cluttered,It is very regular,It will not give people a feeling of emptiness,And TV can not only be placed in the family,As a decorative role。 Its practical role is also very large, so he is very suitable for placing in the family, no matter what size the TV, it should be a must-have in the family.

That's the second reason why I think a TV is a must-have in the family.

The third aspect helps to increase our knowledge and broaden our horizons. There are many types of TV programs, and the one that can help us increase our knowledge the most is the news, which can not only watch some new things that happen in China and in the world every day, but also allow us to learn some new knowledge. Cctv.

They're all really good people, and we can learn a lot from them. There are also many TV series produced by CCTV. There is also the animal world.

And so on, we are able to observe and learn.

You can also learn about animals and how to avoid them if you encounter them again. That's the third reason why I think it's important to have a stereotype in the family.

To sum up, combined with the above aspects, we can understand that a TV should be necessary in the family.

Yes, people in the family generally go to buy a TV, which is also a necessary electrical appliance for the family, and many people will go to some channels and live broadcasts in their lives.

Yes. Many people will buy a TV in their lives, and it is also a must-have appliance for every family, which is very practical. 60 inches can be selected.

Of course not. Nowadays, mobile phones are particularly developed, and most people don't like to watch TV anymore, so they are not necessary for families.

No, because people have very little time to watch TV now, and many people put their time on the iPad or mobile phone, and they can install projectors.

Personally, I think there are three types of televisions: color televisions, black-and-white televisions, and 3D televisions; Of course, color TVs are the most suitable for home use, and 3D TVs are also a good choice if your own conditions allow.

1.Color television

To put it simply, a color TV is a TV with color. Similar to movies, color TVs use the visual residual effect of the human eye to show a little gradient of still images, forming a visual living image, and the visual effect is also better. Color TVs can be roughly divided into 4 categories from the use effect and appearance:

Flat-screen TVs (plasma, LCD and some ultra-thin wall-mounted DLP rear projections), CRT CRT CRT (spherical CRT, super-flat CRT, pure flat CRT), rear projection TVs (CRT rear projection, DLP rear projection, LCOS rear projection, LCD rear projection), projection TV.

2.Black-and-white televisions

A black-and-white television is a type of television that can only display black and white. In the early days of television development, including the recording of television programs and the reception and display of television sets, they could only reflect black and white. A black-and-white TV is a television set that uses a cathode tube screen to display electrons on a screen coated with a fluorescent substance.

Because the fluorescent substance of the screen can only be painted in one color in the early days, when the electrons hit the fluorescent screen, it will show a white bright spot, and the rest of the place is black, so it can only show two colors, black and white.

Television

3D TV is the abbreviation of three-dimensional stereoscopic television. Three-dimensional image TV uses people's eyes to observe objects at slightly different angles,Therefore,Be able to distinguish the distance of objects,The principle of producing stereoscopic vision,The image seen by the left and right eyes is separated,So that users can experience the stereoscopic feeling with the naked eye without the help of stereoscopic glasses,You can experience the immersive feeling,But **slightly high。

In summary

Personally, I think that TVs are divided into three categories: color TVs, black-and-white TVs and 3D TV series, and several types of color TVs are suitable for home use, and can be selected according to personal conditions.

There are 4 types of televisions. It is mainly divided into flat-screen TV, CRT CRT TV, projection TV, and rear projection TV. Flat-screen TVs are suitable for home use, and the advantage of flat-screen TVs is that they are very thin, can be hung on the wall, and the display screen is very large.

Ordinary tube color TV, LCD TV, and LED color TV, plasma color TV; LCD TV is most suitable for home use, because the LCD TV shows more vivid colors, clearer picture quality, and is more friendly to the eyes.

Televisions are generally divided into black and white TVs, color TVs and 3D TVs, if it is an ordinary family, it is more suitable for color TVs, if it is a better condition, you can also choose 3D TVs.

There are three types of TV dramas, namely flat-screen TVs, CRT CRT TVs, and rear-projection TVs. The best TV for home use is a flat-screen TV.

Home TVs are mainly divided into ion TVs, LCD TVs, and at present, 4K TVs have appeared. 4K TVs are comparatively higher in resolution and higher in definition. Here's a closer look at the main differences between the three types of TVs and what are the main factors to consider when choosing a home TV.

Resolution and clarity

LCD TV resolution mainly has 800x x768 and 1366x768 resolutions, and the resolution of 4K TV is more than four times higher than that of LCD TV, and the clarity is naturally better than that of LCD TV. Users can see every detail and every close-up in the picture clearly through 4K TV, and get an immersive viewing effect and experience.

Imaging principles

Plasma TV and LCD TV both belong to flat-screen TVs, but there is a big difference in nature, the main difference is that the panel is different, that is, the imaging principle is different.

And 4K TV and LCD TV both use LCD screens, the physical properties are the same, but the 4K TV panel has a higher resolution, denser pixels, and more advantages in imaging.

A matter of perspective

In terms of viewing angle,At present, plasma TV has more advantages than LCD TV,Although the perspective of plasma TV also has its own problems。 But for home TV, few friends will go to **TV at an angle of more than 120°, therefore, this visual problem is negligible.

Image and image quality display

LCD TVs display images that are analog, while plasma TVs display images that are fully digital. But in terms of image quality, analog images will feel smoother, while digital images will feel jumpy.

Size selection

The size of the TV is not the bigger the better, and the choice of the size of the TV should be selected according to the size of the living room and the distance.

Before buying a TV, you can measure the horizontal distance between the sofa in the living room and the TV screen, if the distance is farther, you can choose a larger size TV. For example, the distance is between two meters and two meters five, and you can choose a TV set of about 40 inches. If the distance reaches about three meters or three meters five, you can choose a TV set of about 55 inches.

Brand selection

Now there are many brands of TVs,Whether it is a domestic brand or an imported brand,Basically, there will not be a big difference in quality,Therefore,You can choose the right TV brand according to your own needs and budget。 If you don't have a high budget, you can choose a domestic brand. If your budget is sufficient, of course, you can also consider imported brands.

Ion TVs, LCD TVs, and later 4K TVs each have their own advantages, and you can choose according to your specific needs and budget. 4K TV, as a new generation of products, is more popular with modern people, if the budget is sufficient, it is recommended to give preference to 4K TV.

The most important TV brands now are so few,The first one,It's Hisense,And Skyworth, these two market shares are the highest,There are also Sharp and Sony, etc.,These are generally more expensive,It belongs to the world's leading technology,And then in general,It's Changhong or Konka or the like,And panda color TV basically belongs to a grade。

Smart TVs, of course, and now it's rare to find a TV without an operating system.

I recommend you to try Japanese brands, Sharp and Sony are very good.

Most of them use LCD TVs and watch digital TV programs.

I hope it helps you. I am honored to be appreciated by you for my sincere dedication! If you are smiling, thank you from the bottom of your heart! If you still have doubts, please continue to ask!

Now that the network is developed, so watch TV, it's all very advanced equipment, and it's generally menstrual TV, of course, it's menstruation. appeared. Projector. So many families are slowly developing in this direction.

The LCD TV we use now, only this brand of TV, we will still use it now.

What kind of TV do you use at home now? I now have a Mi TV at home, and the quality is very good and very clear.

I bought it from Haier, because I occasionally watch TV together at night.

What kind of TV do you use in your home now? Now everyone uses wall-mounted TVs at home,The TV I use now at home is Hisense,The effect is very good,The image is also very light。

The commonly used TV is a wall-mounted LCD TV, which saves space and looks more foreign, but users who occasionally use a TV can also choose a projection TV, which can be hidden and placed on the table when used.

The more commonly used is desktop, and desktop TVs will also be divided into many different categories, such as 50k, 60k, but now many people will choose projectors.

At this time, most people choose the flat type, and some people will choose the liquid crystal type, because it is more comfortable at the time.

The electricity used in commonly used home televisions is alternating current.

Maybe it is a little unsmooth to have knowledge of TV circuits,There are actually two power supply circuits in the circuit of TV,One power supply circuit is the DC pulse excitation switching power supply after the mains is rectified into a DC circuit, and the voltage is supplied to each low voltage and medium voltage circuit; The other is that the line scan circuit outputs impulse voltage through a high-voltage packet and outputs a high-voltage voltage through rectification.

The whole link can also be understood as an organically connected circuit power supply circuit.

In short, to put it simply, the circuits composed of electronic components are DC circuits, but the power supply and distribution are alternating current, therefore, in order to realize the requirements of the circuit, almost all equipment and electronic equipment are the first to convert the power supply and distribution (mains) into direct current and work.

It can be seen that equipment that is not supplied and distributed can also be directly driven by direct current, such as car televisions, radios, etc.

Alternating current, alternating current is easier than direct current in terms of power generation, transmission, voltage conversion, etc., so it is widely used.

There are a number of parameters listed at the time of sale for each TV, and it is recommended that consumers refer to the following indicators when purchasing.

1.Frequency. This is the same as a normal LCD TV, the higher the value, the less obvious the picture shake will be. Generally 50 60hz, high 100hz, and even 240hz.

2.Response time. This mainly depends on whether the tailing phenomenon is obvious when changing the channel, the fast can reach about 4 milliseconds, and the general 6 milliseconds and 8 milliseconds have a good performance effect. This has to do with the chips used in TVs.

3.Contrast. Strictly speaking, contrast is the brightness ratio of the same point on the screen when it is brightest (white) and darkest (black), and the higher the contrast, the more gray scale and richer colors the product can present.

Generally, the contrast ratio of LCD TVs varies from 600 1 to 1500 1.

Now some manufacturers advertise that their contrast ratio has reached 5000 1, or even 10000 1. Xue Hong said that these are actually just a kind of word play for merchants. These data are a "dynamic" contrast,The so-called dynamic contrast refers to the contrast value measured by LCD TV in some specific situations,For example, test each area of the screen one by one,The contrast value of the area with the largest contrast,As the contrast parameter of the product。

Therefore, consumers should not be misled by the merchant's propaganda when making a purchase.

Question: Huawei V65 Sony 65X90J Samsung QX2 are all 65 inches, which one is better.

Answer Sony,This may be a little better after-sales,But Huawei is not too bad,But it still depends on your personal preference for each system,In fact, how much is wrong about the three in terms of hardware,Ask the three brands in terms of function,Color,Which one is higher in terms of configuration。

Ask a question, okay, okay.
