Plasma technology was first developed by major electrical appliance manufacturers in Japan, because compared with plasma technology, ordinary liquid crystal technology and advanced level are much higher. Not only is the response faster and the color more realistic, but it also has the largest short board of LCD, pure black.
At that time, Samsung was actually far behind the five major Japanese electrical appliance manufacturers in technology, but Samsung directly adopted the way of buying plasma panels from the five major manufacturers for sale, which made the five major Japanese manufacturers optimistic about the prospects of plasma.
Because of this, Japan's five major electrical appliance manufacturers decided to increase their investment in plasma and invest hundreds of billions of dollars in Japan and neighboring countries to establish plasma panel production plants. And invest a lot of money to continuously improve the defects of plasma technology, such as screen burning, such as short life and low resolution. With the continuous investment of huge funds, plasma technology tends to be perfect.
In order to confuse the top five Japanese manufacturers, Samsung invested heavily in building LCD panel production lines, and also spent some money on building plasma panel production lines.
Wait until a large amount of funds from the five major Japanese manufacturers have all settled in. Samsung suddenly reported to the European Union that five Japanese manufacturers monopolized the control of plasma panels. Samsung appeared in court as a tainted witness. As we all know, Europe is very strict about monopoly. As a result, the five major Japanese manufacturers have to invest a lot of energy to deal with the accusations and censorship of the European Union. However, little progress has been made in plasma. Finally, in three years, the vice president of a company went to prison in Europe and was fined tens of billions of dollars, ending the lawsuit.
While Samsung is tired of coping with the lawsuit, it is almost overwhelming, promoting a lot of corresponding publicity and promotion about LCD being more advanced than plasma in the market. Almost saturated advertising attacks make a large number of consumers think that liquid crystal is a more advanced technology than plasma. In addition, a large number of plasma LCD panels have been expanded and supplied to the domestic market at a relatively low price. At this point, the consumer's impression has reversed. Looking back, the Japanese found that plasma basically wouldn't have much market. Finally, I can only hold my nose and admit that hundreds of billions of losses have directly hurt all Japanese electrical appliance manufacturers. This is one of the reasons why we now see that Japanese manufacturers are weaker from generation to generation.
What other people say about technical reasons is empty. People who have seen plasma TV generally don't like watching LCD, because there is really no way to compare the contrast of the picture. Moreover, plasma protects the eyes and saves electricity more than LCD TV. Plasma TV is a point light source, which consumes the most power only when the picture is completely white. If the picture is completely black, it consumes almost no electricity. The LCD TV provided by backlight is originally a four-sided lamp tube, and now it is basically changed into an LED light guide plate.
So whether a technology is advanced or not has little to do with whether it can eventually become a winner in the market.
The elimination of plasma TV is not due to backward technology at all. My family bought a Panasonic 42-inch plasma TV in 2005. Now there is no screen burning and no fault maintenance. During this period, my relative's LCD TV (later than I bought it) has been changed, indicating that the quality of plasma TV is not a problem. Moreover, I am used to the bright, transparent and natural picture of plasma TV, and then watching LCD TV feels like watching a plastic picture, so I have never changed LCD TV until now, and the only thing I like is OLED TV.
Let's take a look at the technical advantages of plasma TV compared with LCD TV:
Since plasma technology is much more advanced than liquid crystal, why is it defeated by liquid crystal and turned into antique household appliances?
Panasonic tried to keep the cake for itself, but it backfired.
Plasma display technology was first developed by Japanese manufacturers, so this technology is mainly in the hands of Japanese enterprises. Not all Japanese companies have mastered the core technology of plasma. Among them, Panasonic has the strongest plasma technology and the best display quality, followed by Hitachi, Pioneer, Samsung and LG. These manufacturers can produce plasma panels, but their technology is not as good as Panasonic. Finally, Japanese companies such as Sony, Toshiba and Fujitsu cannot produce plasma panels themselves.
After Panasonic became a leading enterprise in the plasma field, it saw that CRT TVs were facing elimination, and LCD TVs and plasma TVs were expected to rise. Due to the advanced plasma technology, it is expected to unify the TV rivers and lakes, so I want to take the cake for myself and refuse to open the technology to other enterprises. * * * The plasma panel sold is expensive, accounting for 70%-80% of the cost of plasma TV, resulting in the retail price of a 42-inch standard definition plasma TV as high as 2005.
Companies without panels such as Sony, Toshiba and Fujitsu turned to lower-cost LCD monitors. Hitachi, Pioneer, Samsung, LG and other plasma panel companies can't stand Panasonic's greed and short-sightedness, and they have also closed/sold their own plasma production lines (Changhong bought the plasma production line and lost all money) and switched to the LCD camp.
Domestic TV manufacturers are unwilling to be controlled by Panasonic on the panel, and gradually stop introducing plasma TVs and shift their development focus to LCD.
With the growth of LCD camp, the output of panel increases and the cost decreases. LCD quickly occupies the plasma site through price reduction, and at the same time narrows the gap with plasma through technical improvement. By 20 15, plasma shipments had shrunk dramatically, and Panasonic was self-defeating. Later, I had to close the plasma production line and switch to the LCD camp.
In this way, an advanced display technology that might have been popular in the market was eventually eliminated by backward technology because of the greed of manufacturers with core technologies.
I found that everyone thinks plasma is better than liquid crystal. Speaking of plasma, they all say that they bought their own plasma TV in XX. They are very proud and have a sense of superiority. The lines between them are full of melodrama.
What is good about plasma is nothing more than self-luminescence, more natural display color, good dynamic contrast and no smear. Finally, I want to add that you can see it when you watch it together. As you said yourself, if you want to compare them together, it means that the gap is not very big, at least not so big that everyone haggles over every ounce. You know, at that time, many people who went shopping to buy TV sets could not tell the difference between LCD and plasma in the face of two TV sets put together.
These advantages of plasma over liquid crystal mentioned above are also possessed by more primitive CRT displays. Regardless of size, weight and cost, CRT can do better than plasma in your so-called advantages, but it is a pity that CRT was eliminated earlier. Because the inside of CRT is vacuum negative pressure, it needs thick glass and high voltage to realize large size, and its volume, weight and energy consumption are unacceptable. It is difficult for a 29-inch CRT to go upstairs alone, and it is almost impossible for a 50-inch plasma to go upstairs alone. For a 60-inch LCD, it is not more difficult for me to move upstairs alone than a 29-inch CRT.
The above fully shows that compared with these insignificant advantages, the volume, weight and energy consumption that can be perceived at a glance are the most important. The elimination of plasma by liquid crystal is not that bad money drives out good money, but that the potential of technological upgrading is exhausted, and being eliminated is an inevitable trend.
In 2008, I bought a 50-inch Panasonic plasma full HD TV, which is less than 10000, and the dynamic definition is above 1000. Natural colors, pure black pictures can be freely displayed, and dynamic pictures will not be dragged by ordinary LCD TVs. Power consumption is dynamic, which is not much higher than that of previous LCD TVs. The afterimage (so-called screen burning, but by no means screen burning and machine burning that people who don't know the truth think) exists, and it can only be distinguished after it is turned off, and it has no effect in the normal viewing stage. Don't talk big, the viewing effect is as good as ever, and there is no chance to change an oled LCD TV, haha. I bought a 12000 37-inch LCD TV in 2006, and the effect is far less than this plasma.
Plasma quit the market because there are too few people like me who know what to do and too many people who follow suit. Below are the current screen shots (which can't be compressed) and my post on 10.

Let me answer this question. This is a typical bad money drives out good money! Let me draw a conclusion first, and then look at the following when I have time. Liquid crystal tired eyes, very harmful to the eyes, especially LED light source, eyes dry after a long time, plasma can be said to be very green! Let's start with the reason. There are several reasons why LCD is popular: First, it is rich in colors; The second is bright; Third, thinner; Fourth, it is the so-called power saving, so many people will choose. The reason why plasma TV is not popular is the result of comparison with LCD in shopping malls. Everyone likes the picture to be more beautiful and save electricity, but this is not the case. LCD TV pictures are always high-definition and slow animation, because high-speed pictures are too late to respond, but they are blurred and the dynamic colors are not good. As the saying goes, color expression is too hard or not. For example, white, although the liquid crystal is very white, but subtle differences are difficult to show, far less than darker plasma, even if the brightness is adjusted. Power consumption is also inaccurate. LCD is a backlight, and the power consumption after startup is almost only related to the volume, while plasma is related to the volume of the display screen. The brighter the screen, the greater the power consumption. On average, the same size consumes almost less power. Unfortunately, plasma is hard to buy. It turned out that only Changhong did it. I don't know if there is any production now.
Plasma TV was eliminated for the following reasons:
First, the weight is heavy. Take a 50-inch TV for example. It weighs more than 80 kilograms and covers a large area. Generally, manual people are very laborious to move.
Second, the power consumption is large, with a 50-inch power consumption of more than 300 watts. Now more than 200-inch projectors only have more than 40 watts.
Thirdly, the plasma has smear residue in the process of playing, especially in standby. If the standby time is too long, it is easy to burn the screen!
The fourth and most important reason. At that time, there was only Changhong betting plasma in China. At that time, although the technology was leading, due to the technical limitations of Panasonic in Japan, color TV enterprises did not have follow-up research and development, and they were overtaken by LCD TVs in the same industry.
To sum up, plasma TV sets gradually disappeared from the market.
Mainly because it's too expensive.
I worked in a home appliance factory for eight years. When the plasma was born, it directly cut off the rear projection.
But unfortunately, the LCD was born at the wrong time.
In fact, plasma and liquid crystal are still very different. Plasma works like a picture tube. Simply explained, it can be understood as ultra-thin kinescope TV. At that time, due to technical reasons, liquid crystal could not compare with kinescope in color saturation and brightness, especially brightness, let alone plasma.
But the price difference is really very big. I remember that a plasma sold for more than 20 thousand, while a liquid crystal of the same size only cost more than 5 thousand. As for the rear projection TV, it was directly eliminated because of the brightness problem.
The biggest problem of rear projection is fever, and TV station logos are often baked directly on the screen. We don't know how many such complaints we received after the sale. But it can't be helped. This is the characteristic of rear projection. There are many big light bulbs baked in it. It is estimated that the mutton can be cooked.
Personally, if it weren't for the continuous development and compensation of liquid crystal technology, plasma might survive for some time, but with the continuous improvement of liquid crystal brightness and color saturation, plasma will die out directly. After all, their looks are so similar that laymen simply can't understand the difference. At that time, there were many defects in liquid crystals, which was also the focus of our sales of plasma. After all, selling a plasma can directly get two thousand ... but generally it can sell four or five sets at most a year. After all, one or two thousand sets were not decimals at that time, and many people had to save them for several years.
In fact, plasma TV has not really been promoted, and it has gradually faded out of the market for two main reasons!
First, plasma technology was invented in the later period of CRT display. The real production standards and core technologies are only in the hands of two companies, namely Panasonic and Pioneer. Other companies can't develop and produce because of technical barriers caused by patent problems. Plasma is an ideal display device because of its advantages of high definition, high contrast, bright color, high reduction, fast response and no afterimage. Due to the patent and technology blockade, other companies can't produce it, which leads to the phenomenon that the supply of plasma ytterbium plate is tight and the price remains high, which can't meet the market demand.
Second, because of the last reason, because the market is a big cake, and no one wants to give up, other manufacturers can't get the plasma screen, and (including China manufacturers) can only find another way to find a breakthrough and turn to the LCD panel. Because of the technical reasons at that time, the clarity, contrast, color reproduction and response speed of LCD panels were far less than those of plasma. Moreover, in the case of rapid changes in the picture, the afterimage is serious and the yield is low, and only one is better than plasma.
There is also a third-party reason, that is, manufacturers in the market want to grab the market, and then when promoting plasma and LCD, they deliberately amplify the advantages of LCD, saying that plasma is useless, and consumers will listen to what they say when they know these technical things. Gradually, public opinion will guide LCD, preconceived, saying that LCD is good, plasma is not good, and publicity is oriented, so fewer people will buy plasma, so they will gradually fade out of the market! Write here first!
LCD TV will be eliminated soon, and laser tv will dominate in the near future. What needs to be broken now is the projection ratio, brightness and price. But now the projection scale is mature, and you can project 100 inch screen 50 cm away from the wall. If we can break through the projection of 100 inch 30 cm away from the wall, this problem will be solved. Now the lumen in laser tv is about 1.500. If it exceeds 2,000, the curtains will not be drawn during the day, and this problem will be solved. Finally, the price. If the price in laser tv can be reduced to about 6,000 yuan, laser tv all over the country will go crazy. I now watch TV with a low-end traditional projector. To tell the truth, the brightness and color of curtains during the day are acceptable, which is comparable to that of TV theaters at night.
The reason why plasma TV was really eliminated actually involved a huge commercial conspiracy.
The earliest plasma technology was led by major Japanese electrical appliance manufacturers and developed by hundreds of millions of entertainment companies, because compared with plasma technology, ordinary liquid crystal technology and advanced level are much higher. Not only is the response faster and the color more realistic, but it also has the largest short board of LCD, pure black.
At that time, Samsung was actually far behind the five major Japanese electrical appliance manufacturers in technology, but Samsung directly adopted the way of buying plasma panels from the five major manufacturers for sale, which made the five major Japanese manufacturers optimistic about the prospects of plasma.

Plasma quit the market because there are too few people like me who know what to do and too many people who follow suit. This is a screen shot.
Let me answer this question. This is a typical bad money drives out good money! Let me draw a conclusion first, and then look at the following when I have time. Liquid crystal tired eyes, very harmful to the eyes, especially LED light source, eyes dry after a long time, plasma can be said to be very green! Let's start with the reason.

I don't know if there is any production now.
Plasma TV, like OLED TV now, is self-luminous technology, which is much better than LCD TV with backlight display. However, there are several reasons for its decline: First, the power consumption of plasma TV is much higher than that of LCD TV, which is two to three times that of the same size, and its energy saving performance is not good. Second, the resolution is limited by the manufacturing process and cannot be improved under the condition of cost performance. Generally, plasma can only achieve the resolution of 1920x 1080, while liquid crystal 4K has been popularized and 8K has come out. Third, the plasma circuit is complicated. Generally speaking, plasma TV includes the backlight board of the main power board of LCD TV (now these boards of LCD TV are integrated into one board, commonly known as three-in-one board, which is small in size and light in weight), and there are seven or eight boards on Y board and Z board, which greatly increases the cost. Moreover, the failure rate of plasma TVs is also very high because of the high voltage excitation of phosphor. Fourthly, the production process of plasma screen is complicated and the yield is low. However, the current LCD technology is mature, the yield is quite high, the product volume is large, and the cost is greatly reduced. Domestic display manufacturers represented by BOE have occupied the second place in the world, and the price of large screens over 55 inches has continued to fall. You can buy 55-inch 4K smart TVs in the market for less than 2,000 yuan.
Based on the above reasons, plasma technology has been eliminated although it has shown good results. Of course, the current organic light-emitting diode display technology, combined with liquid crystal plasma technology and abandoned their shortcomings, has become the current "network celebrity."
