Linde Electronics, the international electronics division of the Linde Group, has expanded the ultra high definition display production capacity in Asia by acquiring a new plant that complements the high-purity nitrous oxide (N2O) gas facility of Linde.
The acquired plant is located in Zhenjiang in Jiangsu Province of China. The move is expected to enhance the popularity of metal oxide transistors amongst display manufacturers. The acquisition comes in the wake of a new plant installation in Korea and capacity augmentation of an existing facility in Taiwan.
The development of advanced ultra high definition three dimensional (UHD 3D) OLED and TFT-LCD displays at economical costs depends to a large extent on the specialty gas N2O. Current manufacturing methods for UHD 3D displays are expensive as they employ polysilicon transistors that are extremely expensive than amorphous silicon. An economical and far efficient alternative to polysilicon is metal oxide. The latter can enhance mobility of electrons by a factor of 40. Electron mobility is important for incorporating better resolution and frame rates in mobiles, TVs and computers. Metal oxide transistors need N2O in high volumes for their manufacture as the gas is utilized to build thin-film transistor layers that control the resolution.
The demand for metal oxide transistors from display manufacturers is on the rise. The three plants of Linde in China, Taiwan and Korea will help meet this demand to produce high resolution displays. Linde LienHwa (LLH) China has acquired Chinese N2O specialist, Zhenjiang Xinhua Industrial Gases to be equipped to meet the demand for N2O gas in the wake of increasing incorporation of metal oxide transistors in the display manufacture industry.
