Panasonic finally came to an end to the struggle history of the plasma industry. A few days ago, its plasma TV assembly plant in Shanghai was shut down, and all relevant personnel left. It is reported that Panasonic will completely bid farewell to the plasma industry in 2013, and Panasonic's evacuation will also mean that plasma TVs that have prospered in China for 12 years are about to die.
Plasma production capacity shrinks rapidly
It is understood that Shanghai Panasonic Plasma Display Co., Ltd. has been completely shut down and is in a closed state. In fact, as early as November last year, the production line was shut down one after another. The assembly capacity of the plant will be concentrated in the LCD TV assembly plant in Shandong Province. For employees of the original factory, Panasonic China stated that it has resigned or arranged for other factories in Panasonic Shanghai based on its personal wishes.
According to the data, Shanghai Panasonic Plasma Display Co., Ltd. started production in 2001 and is mainly used for plasma panel production and plasma TV assembly. In recent years, the global plasma market has shrunk dramatically, and the Chinese market is no exception. In response to changes in the situation, the production capacity of this plant had to be significantly reduced. Data show that last year's plasma production capacity was only 400,000 units, less than 20% of the annual output five years ago.
When asked if the move meant that Panasonic would withdraw from the plasma TV business, a statement from Panasonic stated that Panasonic had recently decided to concentrate the production of plasma TVs and LCD TVs in China to Shandong Panasonic Electronic Information Co., Ltd. . The purpose is to develop more efficient business by unifying the production functions of flat-panel TVs, thereby enhancing the advantages in the Chinese market.
However, a source close to Panasonic revealed that Panasonic has decided to draw a line with plasma at the end of 2013.
According to the latest industry data, in the first week of 2013, the flat-panel TVs monitored a total retail sales of 733,000 units and sales of 3.24 billion yuan. The sales volume of plasma TV monitoring was 29,000 units, and the sales volume was 130 million yuan, a year-on-year decrease of 7.6%. From this perspective, it is reasonable for Panasonic to shake off the plasma industry.
Panasonic repeatedly tried to rescue to no avail
However, such abandonment is not Panasonic's original intention. Although investment in the plasma sector has seriously dragged down Panasonic's performance in recent years, Panasonic still does not give up the "initial dream" and takes advantage of the plasma industry, so Panasonic does not give up any opportunity to vigorously save the market.
In the first half of 2011, Panasonic stood out from the crowd and made a comeback. At the "2011 PDP International Forum", it announced a high-profile announcement that it will form a PDP alliance with plasma camp companies such as Changhong and Samsung, as well as relevant international industry organizations. At the meeting, Panasonic also said that it will assist the International Information Display Society in implementing two major plans. One is to gather global technology and talent advantages to launch a PDP engineer training program in China. The second is to form a PDP technical route working group by the above alliance.
At that time, the relevant person in charge of the International Information Display Society told reporters that the two plans proposed by Panasonic were actually proposed for the Chinese market. At present, the shipment of flat-panel TVs in the Chinese market has the largest share in the global market, and the decisive market for plasma development is China. Panasonic hopes to start with the Chinese market and solve the global market.
After the emergence of 3D, Panasonic even promoted that 3D will become a magic weapon to rescue plasma. At that time, Panasonic executives said that the plasma TV display method is more suitable for 3D imaging features, making it able to catch up with and surpass the ubiquitous LCD TV, and said that the plasma profit is twice that of LCD. Many companies were instigated by Panasonic, and Cheng Yong, general manager of Changhong Multimedia Marketing Company, said bluntly at the time: "The gross profit margin of Changhong Plasma is more than double that of LCD products."
However, alliances and public opinion campaigns failed to save the plasma market. At that time, many companies such as Skyworth and TCL told reporters that plasma products have obvious self-luminous and energy-saving effects, and do not trail on the dynamic picture, which has obvious advantages. However, companies are still reluctant to venture into this field on a large scale. On the one hand, market awareness is not high, and plasma panel supply is also a problem.
Because there are very few companies investing in plasma panels, Yu Liangxing, general manager of Aowei Consulting, said that the whole enterprise's concerns about the supply of plasma panels are very normal. Taking the Chinese market as an example, the supply to the Chinese market is more from Changhong's two plasma production lines. Once large-scale entry, the risk is self-evident.
It is difficult to support the entire industry by oneself
The Panasonic alliance is too late, because in 2011 the LCD has overwhelmingly made it difficult for the plasma to turn over. As early as 2002, the two display methods of LCD and plasma were equally divided. The plasma camp is mainly Panasonic picking beams, Panasonic hopes to use plasma advantage to get rid of followers. Skyworth Group spokesman Li Congxiang told reporters that Panasonic was reluctant to other companies to "infest" the plasma market. Panasonic had a strong sense of confidentiality, and was afraid of being copied and imitated by its peers. It was unwilling to form a strategic alliance with any company.
At that time, Panasonic's financial strength was strong, which gave Panasonic an illusion that the plasma industry could be enlarged by its own efforts. Other companies do not have any accumulation and technical reserves in the plasma field. Under this background, most of them have retreated from difficulties and started to develop the LCD industry.
Only in 2004, when the prospects of plasma and LCD panels were uncertain, Changhong insisted on launching the plasma production line, which was the only company to follow Panasonic in the plasma market. However, for this move, an industry person who did not want to be named pointed out that Changhong was fooled by Panasonic. Panasonic painted a cake for Changhong and told Changhong that with the help of plasma, Panasonic and Changhong could become two players in the industry. This was also the time when Changhong was high. Regardless of the reason why the crowd has voted to invest heavily in the plasma production line. However, the weak advantages of the two companies still failed to enlarge the plasma industry, and the market was gradually swallowed by LCD.
Panasonic regretted the mistakes he made. In June 2012, Panasonic held a general meeting of shareholders. President Daping Wenxiong apologized to shareholders because in the past few years, Panasonic has invested in up to 485 billion yen in Japan to build three plasma panel manufacturing plants. However, such investment did not achieve profitability for the enterprise. Daping Wenxiong said that the decision to invest in building a factory was a calm judgment at the time, but the advancement of liquid crystal technology has weakened the competitiveness of plasma, and Panasonic will use this reflection as a lesson for future industrial management.
Changhong will be the next Panasonic
It is worth noting that Panasonic's adjustment of the plasma industry had a direct impact on the domestic color TV company Changhong. After the adjustment by Panasonic, Changhong will become the "lone ranger" of the plasma camp.
Changhong News spokesman Liu Haizhong said that the adjustment of the plasma business by other companies does have a certain impact on the development of the plasma industry, but he believes that this is an industrial transformation and structural adjustment carried out in the context of the overall contraction of Japanese panel companies, which is related to the industry itself. Market demand is not relevant.
Instead, Changhong believes that Panasonic's adjusted market space will bring opportunities to Changhong Plasma. Liu Haizhong also revealed that Changhong's current sales will still be strong, and last year's plasma sales exceeded one million. Compared with LCD TVs, plasma still has certain cost-effective advantages, especially in the large-screen market.
Household appliance analyst Liu Buchen pointed out that Panasonic has not made a breakthrough in the plasma market in the context of the rapid development of LCD, and it is more difficult for Changhong to be alone. Panasonic announced the decline of plasma, and the support rate of downstream enterprises will be greatly reduced, so Changhong wants to revive the plasma industry, which is almost zero.
However, industry insiders have also said that if Changhong seizes the opportunity of the big screen, it will improve the situation of plasma marginalization to a certain extent. According to technical personnel, at first the LCD screen was born for the computer, the static image is the best, it is easier to make small, the earliest is to meet the small mobile terminals such as mobile phones, MP3, etc .; and the plasma is born for the TV, the best dynamic image effect It is easier to make a large area. Therefore, the early 32 inches is a dividing line, the LCD screen is generally below 32 inches, and the plasma screen is above 32 inches.
Recently, major companies have entered the large-size LCD panel market, and the claim that plasma will once again usher in development opportunities has also been very popular. This is also the reason why industry insiders speculate that the responsible persons of Samsung TV have expressed that they will not give up the development of plasma-related products.
However, people in the industry are not optimistic about it. Household appliance analyst Liang Zhenpeng pointed out that if in the past few years, large size can save plasma, but now that OLED and other new display methods have come out, companies will not return to the original point to develop plasma.
Comparison between plasma TV and LCD TV:
Q: The difference between plasma TV and LCD TV
A: Plasma TVs and LCD TVs are both flat-panel TVs. They look very similar in appearance, but there are essential differences in imaging principles. Due to the difference in imaging principle, there is a very big difference in display performance between the two, and there are advantages and disadvantages in actual use. Below, the author will analyze it for you in detail.
The principle of LCD TV lighting:
The LCD TV, also known as the LCD TV, changes the structure of the crystal in the thin-film transistor on the liquid crystal panel by current to make it appear. LCD TVs have many features, such as rich colors, up to 16.7 million colors, the resolution of current LCD TVs of more than 32 inches can reach 1366 * 768, most of them support 1920 * 1080 resolution; LCD TVs have a longer use Lifespan, the life of a general LCD TV is about 50,000 hours. In addition, LCD TVs also have remarkable features such as high brightness and high contrast.
Advantages and disadvantages of LCD TV:
Advantages: 1. In terms of appearance, the body of the LCD TV is thinner, especially some of the latest TVs with LED backlight, the thickness is even less than 1 cm; 2. The power consumption of the LCD TV is relatively small, compared with the same The size of the plasma TV is more power-saving; 3. The brightness of the LCD TV is higher, and the picture quality will not change much in a relatively bright environment, and it is still more gorgeous. For static images, LCD TVs are also clearer and more delicate.
Disadvantages: 1. The dynamic clarity of the LCD TV is not high, which is mainly due to the limited deflection speed of the liquid crystal molecules, so the LCD TV will have a tailing phenomenon; 2. The LCD TV has more or less light leakage phenomena , Especially in the dark environment. Because of the problem of light leakage, LCD TVs are not deep enough to render black, and the contrast is not high enough compared to plasma TVs, so the level of the picture is often not strong enough.
Summary of advantages: 1. Beautiful appearance; 2. Low power consumption and power saving; 3. High brightness.
Summary of disadvantages: 1. The dynamic sharpness is not high; 2. There is a light leakage phenomenon, resulting in insufficient black expression and low contrast.
Plasma TV lighting principle:
Plasma TV, also known as PDP TV, relies on high voltage to activate the special gas in the developing unit to make it generate ultraviolet rays to excite phosphorescent materials to emit light. Plasma TV completely eliminates the picture shaking phenomenon, and the high definition, will not cause visual fatigue and damage to the eyes. At the same time, in theory, plasma can achieve an unimaginable big picture. With this technology, theater effects can be enjoyed even at home.
Advantages and disadvantages of plasma TV
Advantages: 1. Plasma TV is better than LCD TV in image hierarchy, especially in the performance of black scenes, LCD TV can not be compared with plasma TV at all; 2. Due to the working principle, plasma TV is compared to The LCD TV has higher dynamic clarity, and the performance of high-speed sports pictures such as sports games and action movies is smoother, and there will be no tailing; 3. The plasma TV is still the only TV that can be fully digitalized at present, without going through D / A conversion can avoid the degradation of image quality caused by image signal distortion. The LCD TV must control the brightness and gray scale through the analog voltage, so there is still a certain loss in the image signal during transmission.
Disadvantages: 1. The appearance of plasma TVs cannot be as slim as LED-backlit LCD TVs. For users who care about the appearance of TVs, plasma TVs are not pleasing; 2. Plasma TVs have a low brightness due to luminous efficiency issues It will not be as high as an LCD TV with an independent backlight, so in a brighter place, the viewing effect of the plasma TV will be greatly reduced. It is also due to the problem of luminous rate. In order to improve the brightness, plasma TVs are naturally larger in power consumption than LCD TVs. 3. Plasma TVs still have the imagination of burning screens. The so-called burning screen is that the plasma TV keeps a certain picture for too long (with the development of plasma technology, this time is getting longer and longer), will make a certain picture stay on the TV for a long time. However, under normal circumstances, this phenomenon will disappear after a period of time.
Summary of advantages: 1. Outstanding color; 2. High dynamic clarity; 3. No signal loss during the full digitalization process.
Summary of disadvantages: 1. The body is slightly thicker; 2. The brightness is lower and the power consumption is higher; 3. There will be a screen burning phenomenon.
