The advantages of the PDP display itself highlight the considerable prospects of the domestic market

In the next two decades, the time allocation pattern of human beings in work and life will not change much, and people’s reliance on display screens will become more prominent beyond rest time. We can imagine our life is such a picture: Our indoor environment will be used in a wider range of display (or called the display wall), the display not only has the traditional function of the TV, or part of the interior decoration And the platform for external information exchange, the display wall will change the interior decoration backdrop according to our needs, and at the same time, it can also exchange information through the display wall to increase the exchange space and improve the efficiency.

The development of PDP display technology, while highlighting its own advantages, also overcomes its own high energy consumption deficiencies. PDP power consumption has been decreasing at a rate of 30% per year over the past three years. According to data from the changes in energy efficiency of flat-panel TVs released by the Consumer Electronics Association (CEA) in February 2011 for nearly six or seven years (Figure 1 below), the power consumption of PDP products has dropped significantly since 2009. The power consumption is reduced to about 270W, and the corresponding LCD has an average power consumption of 290W. By 2010, the power consumption of PDP 42-inch products has also been reduced to around 95W, which is almost similar to that of LED and LCD products of the same specifications; the power consumption of 55-59-inch PDPs has dropped to about 200W, which is comparable to LCDs of the same size segment. Changhong has also made breakthroughs in the development of PDP high-efficiency and low-power technology recently. By adopting a new type of calcium-doped magnesium oxide protective film material and low-power driving technology, the luminous efficiency has increased from the original 1.8 (lm/W) to 2.6 ( Lm/w), making the PDP's overall power consumption drop by 40%, which is at the international leading level. In the next few years, PDP will adopt "evolutionary" technologies - new dielectric protection films, high helium content working gases, low dielectric constant media, new high-efficiency 3D phosphors, new low-power cell structures, Low-reflection, high-transmission filter films and low-power driving methods reduce power consumption. The power consumption of PDPs will reach 2 W/inch, and the average power consumption of a 100-inch display wall will be about 200 W. In addition, "revolutionary revolutionary" PDP display technology is gestating. As mentioned earlier, each pixel of the PDP is like a small fluorescent lamp. The efficiency of a fluorescent lamp can reach 100-120 Lm/W. However, the existing plasma television has a luminous efficiency of only 1.8 Lm/W, and the energy conversion efficiency is lower than 2%. In fluorescent lamps, there is a lot of room for improvement in luminous efficiency, and there is ample room for PDP technology development. Of course, since the PDP pixel space size unit is far smaller than the fluorescent lamp size, a positive column region with high luminous efficiency cannot be realized in a conventional PDP cell, but a high-efficiency light-emitting mechanism similar to the characteristics of the positive column region has been found, and it is expected that the future 5 - Within 10 years, achieving a luminous efficiency of 20-40 Lm/W on a new generation of PDPs is completely achievable.

The advanced nature of technology is an important prerequisite for the success of the industry, but it cannot guarantee the ultimate success of its industry. The early PDP technology was mainly controlled by Japanese household electrical appliance companies. The expansion of technology promotion and production scale was relatively conservative. As a result, electronic companies in South Korea and Taiwan had obvious lags in PDP technology and could not follow-up and expand on a large scale, affecting in some degree. The development of the PDP industry. In recent years, the PDP industry has seen new developments. Matsushita has completed the integration of Japan's PDP industry, and its low-power consumption and high-definition technology have developed rapidly. South Korea's PDP industry chain has been gradually improved with rapid technological progress and low-cost technological achievements. China's PDP has also developed rapidly. In 2006, Changhong Group invested 675 million U.S. dollars to build the country’s first plasma screen base, dedicated to exerting strong market forces on the basis of mass production, and establishing “China PDP regional industrial clusters” with government support. . In July 2009, Hefei Xinhao invested about RMB 2 billion to purchase a Hitachi 4-sided production line with a production capacity of 1.5 million units/year (measured in 42-inch units). The project has already started trial production and it is expected that its first products will be Listed during May Day. The rise of the PDP industry in China has promoted international exchanges and cooperation among the PDP industry and gradually changed the relatively closed R&D method of PDP technology. Currently, Panasonic and Changhong are continuing to expand their new capacity. Shanghai Panasonic will introduce the Panasonic P3 production line in Japan, with an annual output of 3 million pieces, and Changhong will expand its production capacity to 3 million pieces per year. After this round of investment construction is completed, China's domestic PDP module production capacity will reach an annual output of 600-700 million.

While developing PDP display production, Changhong is committed to the construction of the PDP industry chain in China. It has initiated the establishment of four localized alliances for PDP key materials, key components, key equipment, and technological innovation, integrating domestic superior resources, and expanding the PDP industry camp. Seek sustainable basic capabilities for industrial development. Since 2009, encouraged by the expansion of PDP production capacity in China, the domestic PDP industry chain manufacturers have also accelerated their industrial supporting capabilities. It is expected that by 2012, the localization rate of key devices will reach over 90%; the localization rate of screen materials will reach 80% will further reduce production costs. Driven by record sales in 2010 and plasma 3D TV demand, PDP companies will further shorten production cycles and increase production capacity in 2011. The PDP industry has entered a healthy virtuous circle.

The future of highly-developed information for indoor display is large size, high resolution (including static and dynamic), 3D, natural color, high contrast, and low power consumption. Through continuous technological innovation, especially the progress of high light efficiency and low power consumption technology, PDP display technology can fully meet the requirements of future display. Compared with the current various display technologies, all picture quality of the PDP is the benchmark of other flat panel display technologies except the contrast of the bright room. The PDP technology not only represents the past and the present, but more importantly represents the future. Due to the advantages of PDP materials, devices, processes, and production costs, the PDP is particularly suitable for growing in China. The development of the PDP industry in China will greatly promote the development of the global PDP industry to meet the needs of future information display.
