The advantages and disadvantages of CRT CRT TVs and LCD TVs, which effect is a little better

Previously it was the high brightness of CRT. Now the backlight of the liquid crystal is LED, which is 120% of the brightness of the CRT. 50% longer lifespan; Electricity consumption is half that of CRT. Liquid crystal is the mainstream.

LCD TV is good! It's a good hair, you have to fix it if there is a problem, and the goods are expensive enough. There was a period of time to help others repair, but if they couldn't repair it, they were relied on, what a dead guy, and the 56,000 yuan TV was said to have been repaired by a repairman.

The brightness of the CRT is definitely lower than that of the LCD, with a maximum average brightness of 100 nits for the 29" CRT and a minimum of 400 nits for the LCD.

The contrast ratio of CRT is higher than that of LCD (because LCD has light leakage); CRT reproduces moving pictures better than LCD, and LCD reproduces still images better than CRT;

The color gamut range of CRT is higher than that of current LCDs;

Among LCD OLED, PDP, SED and other flat panel displays, the best performance is SED (equivalent to concentrating millions of smile CRTs), but the best performance and marketization are two different things.

The image of this TV will be clearer, and we will feel like we are there when we watch TV.

The colors are more pretty, and when you look at the TV, Hail Ridge is like appreciating a work of art.

The material will also make the TV last longer, which can allow us to save money even more.

The advantage is that it can bury the bending circle to the greatest extent to restore the color, the brightness can be restored, the contrast is also very good, and the response is also very agile, very fast, and the angle will be more.

1.Clearer picture quality; 2.The screen does not hurt the eyes, and the light sense is not strong; 3.The color difference is small, and the color will not be too bright; 4.**Cheap; 5.Low pollution.

Of course, it is a projection TV, which can be transferred from the living room to the bedroom projection, and it can also be outdoors, which is obviously more convenient than CRT display tube TV.

Projection TV is better, people can watch TV at home, and the bezels are wider.

Personally, I think flat-screen TVs are better. But flat-panel TV and CRT CRT tube TV both have their own advantages and disadvantages,Can't completely compare which type of TV is better,Let me explain it in detail for you,Advantages and disadvantages of flat-panel TV and CRT CRT CRT TV。

The first category, flat-screen TVs.

The advantage of flat-screen TVs is that they are relatively thin and light, and the appearance is more fashionable, which is more suitable for today's society. It can protect people's eyes and has a long service life. One of the biggest advantages of flat panel electric chaos is that it is similar to a flat panel,That is, it is relatively light and thin,It also gives people a better visual experience on the outside,And in**TV,It has a better viewing experience,It looks fashionable,Suitable for today's society,Because of the continuous progress of society now,The appearance of TV is also constantly changing。

When the flat-screen TV is in the first place, the brightness and contrast will not be very strong, so it will not stab people's eyes, which also plays a role in protecting the eyes. Although the flat-screen TV looks relatively thin and light, its service life is still very strong, because now that the technology is updated, its service life is also longer with the progress of technology.

The disadvantage of flat-screen TVs is that they are relatively expensive, and ordinary families have to buy them with a lot of budget. It's more likely to be damaged because flat-screen TVs are too thin and light to damage if you accidentally hit them.

The second category, CRT CRT TVs.

The advantage of this type of TV is that it is relatively cheap. The image is clearer, and the contrast and brightness are better in all aspects. Because its principle is that the electron beam hits the phosphor for a reflection, it will be stronger in terms of brightness, contrast, and picture sense, and it will also give people a better viewing experience, and it is also very cheap.

CRT picture tube TV disadvantage is that people's eyes are not too friendly to the skin,Because of the brightness,The contrast is very strong,So a long time ** may damage human eyes,And because its principle is to use an electronic beam to hit the phosphor,With the growth of use time,Its picture sense will become bad,So its service life is short。

To sum up,The above aspects briefly describe the advantages and disadvantages of flat-screen TVs and CRT CRT CRT TVs。

CRT CRT picture tube TV,It's better,It's more phased,Very clear,It looks more enjoyable,It's also great to play movies。

Flat-screen TV is better,The sense of experience is relatively strong when a**,There will be no jamming,**It's also cheaper。

A flat-screen TV is a little better, the clarity of such a TV is better, and you will have a very good feeling when you use it.

With the development of the economy now, there are many types of TVs, among themCRT TVIt is an early TV product, which was very popular with everyone in the past, but now there are not many friends who know about it, so what are the advantages and disadvantages of CRT TV? What is the principle of CRT TV? Let's follow us to find out.

What is a CRT TV?

The structure of a CRT television is a vacuum tube with one or more electron guns inside. The electron beam is emitted by an electron gun. When an electron beam hits the inside of the screen surface in front of the vacuum tube, the luminescent paint on the inside of the screen produces an image due to the impact of the electron beam.

This is how CRT TVs work. Most of today's thick, bulky and bulky TVs use this technology. CRT TV has a long history, after years of innovation and progress, its technology has gradually matured, and the picture quality has reached a very high level.

And it's relatively cheap, so it's still relatively cost-effective, which is relatively good.

What are the advantages and disadvantages of CRT TVs?

Advantages of CRT TV: CRT TV has a low ** and high cost performance. It is brightly colored. If our TV is broken, it is easier to repair it, and the cost of repair is lower.

Disadvantages of CRT TV: CRT electric Jianshi machine is relatively bulky, more troublesome to move, and takes up a lot of table space. Its radiation will be greater than that of liquid crystals, so we can't close it for a long time, otherwise the eyes are susceptible to radiation and myopia.

However, if we are at a normal distance** and not for a long time continuous**, there will be no problem.

What is the principle of CRT TV?

CRT TV principle: CRT monitor (scientific name "cathode ray picture tube") is such a device, which is mainly composed of electron gun (electrongun), deflection coils (deflectioncoils), shadow mask (shadowmask), high-pressure graphite electrode and phosphor coating (phosphor) and glass shell. One of the things that impressed us the most was definitely the glass case, which can also be called a phosphor screen, because its inner surface can display rich color images and clear text.

How does the CRT display use the principle of three primary colors? Of course, instead of directly painting these three primary colors on the phosphor screen, the CRT display (scientific name "cathode ray picture tube") is controlled by an electron beam, which is mainly composed of five parts: electron gun (electrongun), deflection coils (deflectioncoils), shadow mask (shadowmask), high-voltage graphite electrode and phosphor coating (phosphor) and glass shell. Among them, the most impressive thing is definitely the glass case, which can also be called a phosphor screen, because its inner surface can display rich color images and clear text.

The above is for you, what are the advantages and disadvantages of CRT TVs? What is the principle of CRT TV? All of it.

Generally speaking, it is large in size, not environmentally friendly, highly dangerous, and harmful to the human body.

The biggest advantage: large brightness, bright color The biggest disadvantage: large volume, large radiation, and power consumption.

CRT CRT tubes are highly radiated and unhealthy.
