In order to meet the requirements of LTPS and OLED two key display technology, Corelle launched a dedicated Jade glass

Jade glass can be applied to low temperature polysilicon (LTPS) and organic light-emitting diode (OLED) these two key display technology, so as to solve the challenges faced by today's mobile electronic equipment industry. Unlike other manufacturers of glass substrates, Corelle's Jade glass does not require two heat treatment without polishing to meet the requirements of surface quality and thermal stability of LTPS and OLED processes.

Jade glass allows customers to implement more stringent design standards, so that they can be more direct integration of electronic devices on the glass. The equipment manufacturers, this integration means lower costs and higher design flexibility; and for consumers, the final result is the electronic equipment display brighter and clearer, longer battery life and more compact.

Compared with the amorphous silicon (a-Si) process for the production of liquid crystal TV sets and liquid crystal displays, the requirements of LTPS technology on temperature, surface and size are more stringent. Through its chemical properties, Jade glass has thermal stability improvement, coupled with the melting process optimization, Jade glass can achieve the required quality standards of today's LTPS technology, and has potential and space for future further innovation. In the past, using LTPS technology to the production of liquid crystal display manufacturers have to use the traditional a-Si glass, the glass is needed after two times of heat treatment or special polishing, surface quality and surface characteristics which may damage the glass substrate.

OLED technology breakthrough

In addition to the application of LTPS-LCD technology, Jade glass also provides excellent surface quality and thermal stability for the production of OLED displays. OLED display can rely on organic components to achieve self luminous.

At present, the two technical challenges hinder the development of the OLED industry and restrict its application in small displays. The first challenge is the performance of polysilicon backplane. "As a current driving device, OLED display to backplane" higher quality than the conventional liquid crystal display, Corelle chief executive Peter L. technology in East Asia, Dr. Bocko said, "provides flexibility in the production process of Jade glass for customers to help them achieve the optimization performance of OLED. "

Another challenge is how to protect OLED devices from environmental problems. The OLED materials are sensitive to moisture and oxygen, the industry has been a need not reduce the equipment size and optical quality, with expansion sealing technology ", Bocko said," this is the Corelle company now is developing called Vita? OLED encapsulation equipment causes solutions. This new technology can cause a sealing space, blocking moisture and oxygen, thereby enhancing the life of OLED display equipment. The company is in talks with potential customers in the hope that it will be able to launch this high-performance sealing solution in 2008.

Jade glass products and Vita sealing scheme is independent of each other, but the combination of the two can be a significant breakthrough for OLED display devices. "The Jade glass and Vita program, we can solve two big problems facing the OLED industry: product life and backplane performance", Bocko said, "this launch two products will help OLED technology has been applied to the larger size of the display. "

market demand

Today, with the rapid development of portable electronic equipment, the introduction of Jade glass meets the needs of the industry. Corelle display technology division president Ji Kebin said: "great success although now on the market a lot of attention focused on the LCD TV, but historically, the new technology of small electronic equipment market is the test stage, the market is expanding rapidly. The latest industry data show that the use of Jade glass support LTPS and active matrix OLED applications share has accounted for 20% of the small and medium display market, by 2011 the figure is expected to grow to 33%.
