Display device lively sound components
Overall, the global LCD industry is still showing growth and prosperity, which also led to the rapid growth of domestic industry. At present, the LCD industry has entered a new period of development, from the perspective of industry chain in 2006, TFT supply and demand roughly in balance, the second half of 2007 will be strained.
Construction industry is still hot
2006, China's TFT-LCD production line construction
Climax, the first is the "Parc Royale project" surface, followed by BOE shares Julong Photoelectric work together to build a 6th generation LCD panel production line. Chi Mei Optoelectronics and then settled in Foshan, the back-end LCD module plant has officially started in early May,'s first seventh-generation LCD panel production line was settled. Then Corning built in Beijing Economic and Technological Development Zone in China's first liquid crystal display (LCD) glass substrate finishing facility. Subsequently, LG-Philips LCD (Guangzhou) Co., Ltd. and related items located in Guangzhou Science City, a formal agreement signed in Guangzhou, Guangzhou will invest in the latest generation (ie, the 8th generation) LCD production line, etc., large-scale construction TFT-LCD production line momentum intensified.
As the TFT-LCD industry to flourish, into the liquid crystal display device era. Whether it is large-size displays, notebook computers or LCD TV, or small-sized high-resolution color screen mobile phone, PDA, GPS, etc., other types of LCD panels is eating away at the product market, thus achieving unified situation. However, the rapid development of LCD panel, PDP, OLED is also rapidly emerging, especially the PDP in 2007, TFT-LCD will constitute no small threat.
PDP feel the pressure
While the domestic flat-panel LCD TV market PDP development as strong, but the forecast shows that in 2007 China PDP TV sales will exceed 100 million units. The DisplaySearch statistics also show that in 2006 global sales of PDP nearly 10 million units by 2010 will reach 25 million 30 million units. Especially in the U.S. and European markets, PDP 42 inch and above market is accounted for close to 70% market share.
In the United States this year on the Las Vegas Consumer Electronics Show, Panasonic announced the development of a 42-inch 1080p HD Plasma (PDP) display prototype. This Full HD plasma display screen resolution up to 200 million pixels, compared with the previous 42-inch HD plasma flat-panel TV with high resolution more than twice. Panasonic PDP's force, and a direct threat to large-size TFT-LCD applications in the market. Some experts said that 2007 will be the plasma (PDP) making determined efforts of a large outbreak of the year.
Domestically, Changhong's PDP with the project is well underway. Some experts predict that technology integration is complete, Changhong will be in the PDP in all aspects of the industry chain has become its capability, Changhong in the development of PDP projects are bound to accomplish something.
At the same time, OLED development should not be ignored. OLED panels are difficult to achieve because of large size, are used for mobile phones or digital cameras, but this year the U.S. Consumer Electronics Show in Las Vegas, Sony demonstrated a 11-inch OLED TV, the product gives us the wonder is not size, but the production level, this information for the TFT is concerned, is not good, is the addition of a rival.
There are indications that in 2007, TFT will face greater market pressures, but whether it is mobile phones, MP3 or laptop computers, televisions, liquid crystal display devices into the era is indisputable.

Second, focus on various size LCD with LED backlight, a small area of the cell phone, MP3, MP4, PDA, digital cameras with the backlight, the middle area of about 9 inches to 20 inches for the terminal display and LED backlight large area LCD TV's backlight, with hundreds of billions of these potential markets.
2007 China will issue 3G licenses, 3G market, the launch will be in small size LED backlight market growth. At the same time, large-size backlight market to become the new darling of companies. Implementation of EU environmental standards have been put forward, as the traditional cold cathode fluorescent backlight large-size LCD panel's position precarious. The green LED by virtue of its characteristics to win the attention of the manufacturers, LED backlight LCD size is small to large-size LCD backlight applications forward.
For the three-color LED backlight is still there red, green and blue color of the LED is inconsistent attenuation problems affecting the white LED life. The switch to LED as backlight source is related to the circuit would also require re-design. These problems to some extent, affected the large-size LCD LED backlight into the market pace. 2007 LCD TV backlight market is not started will wait and see.
In addition, a variety of car lights, such as front and rear lights, turn lights, side lights, brake lights, headlights, interior lights and instrument panel displays, will enter the development and application of the potential market of hundreds of billion yuan.
