The working principle of PDP screen is that the HE-Xe or Ne-Xe mixed gas in the discharge unit is excited by electrode discharge and emits 140-200 nm ultraviolet rays. This is the basic structure diagram of its unit, which includes three primary colors as a whole, and three different phosphors are used to produce colors.
From the above table, we can sum up the advantages of PDP: clear dynamic influence; Relieve eye fatigue; Rich and delicate drawing paper; Large viewing angle, no discoloration; Self-luminous ability. The advantage of PDP as a TV display is that its dynamic range is ahead of LCD in terms of stereoscopic impression and dynamic sense of image quality. The structure of PDP is that it can fully display the necessary brightness in the necessary position. PDP can make the black place darker and the bright place brighter, which is better than LCD.
The reaction speed, the moving picture on the left is very clear, while the liquid crystal on the right is almost the same. Although LCD has made continuous progress in this respect, PDP is still relatively better. From the perspective, the LCD on the right is only 90 degrees, the PDP is 160 degrees, and the data reference point is measured when the brightness drops to 1/3. From a single point of view, the LCD on the right can reach 80 degrees. Color reproducibility, the left shows the color reproducibility of LCD light source, and the right shows the performance of PDP.
Regarding the service life of PDP, the current service life of PDP is 60,000 hours. If you use it for 8 hours a day, you can use it for 20 years. Of course, PDP is constantly improving and perfecting. The ultraviolet rays generated are 147 nm and 173 nm. Currently using 147 nm. If 173 is used, the loss of phosphor will be reduced, which means the service life of PDP can still be improved. In terms of power consumption, the rated power of PDP is large, but the actual power consumption is equivalent to that of LCD. PDP changes the power consumption according to the picture load rate, and the monthly electricity cost of 40-inch PDP and LCD is equivalent. The larger the size, the more favorable the PDP is. From the resolution point of view, PDP can also achieve full HD display at present, and the 50-inch full HD display was completed in 2005, and it will be even bigger in the future. From the contrast point of view, LCD images are more vivid under the strong illumination of manufacturers, while PDP performs better under the illumination of real families. If used in ordinary families, the use of PDP will be more obvious. This picture is a summary of what has just been said. From the middle picture, PDP is superior to LCD in many aspects, including resolution, bright room, dark room and gray scale. In terms of price, PDP is relatively low for LCD.
Let me briefly talk about the development of PDP in the world. At present, the size of PDP can achieve 32-inch display by 2007, and it is expected that it can be mass-produced by 26-inch next year. North China's PDP is the best consumer market in the world, followed by Japan, followed by Europe, with a growth rate of 20%, and then the market, which is expected to reach 654.38+million in 2007 and 2 million in 2008, showing that this product is second only to LCD.
Here is a brief introduction to Changhong's plan for PDP production capacity. Changhong Company is entering and integrating the upstream and downstream resources of PDP to make efforts for the healthy development of domestic PDP industry. At present, Changhong PDP TV boutique lineup, 600 series, 700 series, 88 series, 66 series and other product lineups are serialized, covering 32- 103 inch. Our product strategy, the first is to realize the transformation of upstream and downstream industrial chain and the vertical integration of upstream and downstream resources. Increase the development of products with sizes over 50 inches, consolidate the advantages of large-size products, and extend to small-size areas of 32 inches and below. Achieve a new technological leap and achieve the best combination of application and experience.
The above is a brief introduction to Changhong PDP.
26-inch plans to adopt LG panel next year and launch it in the second half of next year, depending on the progress of LG panel.
32 inches, there are currently three companies capable of providing 1024*768 panels, of which LG is the fastest at the end of the year, Panasonic and Samsung are early next year.
37-inch 1366*768 panel, which Panasonic is developing and plans to launch next year.
Changhong also has a 58-inch PDP, which plans to use Panasonic panel, depending on the model set by the subsequent planning department.
Next year, the independent production line plans to provide 32, 42, 50, 60 and 65-inch panels and complete machines.
Now Changhong Organic Light-emitting Diode Project has been started, and the follow-up research and development has been gradually launched. It is estimated that around 20 10, mass production models of 32 inches and below can be provided, so that large and medium-sized PDP will be used, and small-sized organic light-emitting diodes will be used, and Changhong upstream will have the absolute right to speak. The significance of organic light-emitting diode is that it can gradually replace the position of small-size LCD. If the cost and technology break through, it will first gain an overwhelming advantage in desktop display and small-size TV.
Adopted the Proposal on Establishing Sichuan Hongshi Display Technology Co., Ltd.
According to the needs of the company's development strategy, in order to further strengthen the company's core technical capabilities in display technology, the company decided to develop the organic light-emitting diode (OLED) industry and build a new generation of display devices. It is agreed that the Company and Chengdu Hi-tech Investment Group Co., Ltd. (hereinafter referred to as "Chengdu Hi-tech Investment") jointly contribute to the establishment of "Sichuan Hongshi Display Technology Co., Ltd." (tentatively named as "Hongshi Company"). Hongshi Company plans to have a registered capital of 600 million yuan, and the company contributes 360 million yuan, accounting for 60% of the registered capital of Hongshi Company, including 270 million yuan in cash and 90 million yuan in fixed assets. Chengdu Hi-Tech Investment invested 240 million yuan in cash, accounting for 40% of the registered capital of Red Lion Company.
The registered address of Hongshi Company is Chengdu High-tech Industrial Development Zone, Sichuan Province, and its business scope covers R&D, manufacturing, sales and service of organic electroluminescent display devices and their modules, head-mounted displays and mobile displays, and electronic products.
Organic Light-Emitting Diode (OLED), whose Chinese name is "organic light-emitting display", is also called organic light-emitting diode or organic electroluminescent display (OEL). It is a display device driven by electric field, which makes organic materials emit light through carrier injection and recombination. Organic light emitting diode (OLED) is the third generation display technology after CRT (first generation), LCD and PDP (second generation), which represents the development direction of display technology at present and is called "dream display" in the industry. Chengdu Hi-tech Investment, the partner of Hongshi Company, is a wholly-owned subsidiary controlled by the government of Chengdu Hi-tech Zone with a registered capital of 654.38 billion yuan.
The above prices are current transaction prices, which vary from place to place. It is normal that the price difference is about 5%. If the increase is above 10%, you can bargain-hunting, which is a bit high.
