20 years ago, plasma TVs were deeply loved by the public due to their excellent technology and display effects. People often said that "laymen buy LCD, experts choose plasma", which shows that plasma TVs have an unusual status in people's hearts. .
Nowadays, big data tells us that strong technology does not mean long-term development. LCD TVs have become the mainstream, while plasma TVs, which were popular in the past, are gradually being forgotten. What happened in this?
In 1964, several American scientists jointly produced the first plasma panel, which was also the beginning of plasma technology. Until 1993, Japan's Fujitsu Company took the lead in manufacturing the first commercial plasma TV with a resolution of 640x480 and the ability to display 260,000 colors.
In the early days of plasma TV, a 42-inch plasma TV cost about 200,000 yuan. Around 2000, 200,000 was not a small amount of money for most families, which also made plasma TVs an unattainable dream for many people.
Due to the high price of plasma TVs, people are out of reach of them. In order to meet the demand for watching TV, most families prefer to buy CRT TVs with mature technology and low prices.
With the advent of LCD TVs, the market share of plasma TVs has been continuously divided. In order to cater to the market, plasma TVs have to be sold at reduced prices. The price of plasma TVs of the same size has dropped to less than 10,000 yuan, which also allows it to enter the market. Thousands of households, sales have once again ushered in "spring".
However, while plasma TVs and LCD TVs compete with each other, they also invisibly replace the commonly used CRT TVs.
Plasma TV consists of plasma display screen, digital processor, tuner, interface board and other parts. Plasma TVs are deeply loved by people because of their excellent color, brightness, uniformity, viewing angle and thin and light appearance. The display size can reach up to 103 inches and is widely used in public places and as outdoor display screens.
Both LCD TVs and plasma TVs have pixel-level self-luminous technology. Each pixel emits light independently without the need for a backlight. When black is displayed, light leakage, whitening, etc. rarely occur.
However, compared with LCD TVs, plasma TVs have higher brightness and can enjoy large-screen TV programs under sunlight. They have good color reproduction performance and can provide exceptionally bright, uniform and smooth pictures.
In addition to good display effects, plasma TVs also have the advantage of low latency. The delay time of most LCD TVs is around 10ms, and some better-performing monitors can reach 1ms. However, the delay time of plasma is in the microsecond range, and lag is almost unnoticeable during use.
In addition, it also has the function of preventing electromagnetic interference. The display principle of plasma TV has nothing to do with electromagnetic fields, so external electromagnetic interference has almost no impact on plasma images. Once early CRT TVs were subject to electromagnetic interference, the images would be tilted and deformed.
When plasma TVs withdraw from the market, we must first start with its own shortcomings. While there are many advantages, the shortcomings cannot be ignored.
High price and high power consumption
In China, plasma TVs cannot be popularized, which is partly related to the price. Domestic LCD TV prices generally range from 3,000 to 8,000 yuan, while plasma TV prices have remained high, with slightly cheaper ones costing 8,000 or even more than 10,000 yuan.
Since the pixels on the plasma display screen emit light independently, the power consumption increases greatly. The power consumption of a display screen is much higher than 300 watts, and it is also known as the "electric tiger". .
When the power is high, the heat will also increase. After a long standby period, touching the back of the TV will make your hands hot, and the overall heat dissipation effect is not ideal.
Screen burn-in is easy
Plasma TVs are prone to screen burn-in after long-term use. The so-called screen burn-in means that the TV stays on the same screen for a long time, and in severe cases, a black screen may appear. As the use time increases, the temperature of the internal parts and screen of the TV will also rise, and residual images may remain.
In addition to the defects of the product itself, there are also some industry competition issues
Plasma TVs rely on display effects to attract countless fans in the market. Although there are some inevitable shortcomings, they are not to the point of delisting. And almost none of today's electronic products are flawless, and there are more or less defects. But as long as it does not affect the overall use, people will still choose to tolerate and accept them.
For example, OLED TVs have problems with screen burn-in and short lifespan, but this does not affect it in any way from becoming a mainstream product today. Therefore, the delisting of plasma TVs has little to do with product defects, and is more caused by industry-level factors.
With the continuous development of the times, new electronic products that are larger, thinner and lighter are constantly refreshing people's visual senses. Especially the rise of smart phones and tablets has put plasma TVs to an unprecedented test.
Due to the rapid rise of mobile phones, tablets and other electronic products, the situation of "small screen dominance" has become increasingly obvious. The frequency of use of TVs has gradually decreased, and sales have also shown a downward trend.
In this context, plasma has exposed its fatal drawbacks. Because it can only produce large-size TV screens and cannot apply the technology to mobile phones or tablets, it cannot keep pace with the times. LCD TVs, on the other hand, rely on their own advantages to stabilize their market position. They can be produced in sizes ranging from 100 inches to 1 inch, and their business scope has also been expanded.
Complex generation technology
LCD TV panel manufacturing technology is relatively complex, while image processing and driving technology are relatively simple. Plasma technology is exactly the opposite of LCD TV technology. Whether it is circuit design or image processing chip technology, it has high requirements for researchers, and it is also difficult for manufacturers to learn.
Although plasma technology was first discovered by Americans, at that time the core technologies were almost all controlled by Panasonic, and they refused to share technical resources with other companies. It was precisely because of the exclusive technology that plasma TVs are sold at a high price, making it difficult for other manufacturers to ensure profits.
Looking back at the development history of LCD TVs, it is a healthy market competition. There is no technology monopoly. Manufacturers have the goal of winning through cooperation and invest heavily in capital and technology to improve areas that are insufficient. , improve quality.
Nowadays, technology has been able to satisfy most consumer groups, and the price also has an advantage, several times cheaper than the price of plasma TVs more than ten years ago.
Due to the above reasons, plasma TVs are gradually disappearing from the market. Of course, there may also be problems with the leader's decision-making.
From the issue of plasma TVs, we can also learn that if a product wants to keep pace with the times and develop in the long term, it must not only have its own patented technology, but also learn to cooperate to win, in line with Current market demand.
