Taiwan's aggressive investments in
R&D are essential to keeping it at the top of the global flat panel display industry. One of the latest advances in this field here was introduced recently by the Electronics Research and Service Organization of the Industrial Technology Research Institute recently: the development of a 3.8-inch double-sided monochromatic flat panel display active matrix OLED (organic light-emitting diode) display (AMOLED). Following Samsung in South Korea and Pioneer in Japan, ERSO is the world's third organization to develop such a double-sided display.
LTPS (low temperature polysilicon) TFT (thin film transistor) and OLED are two important areas of development in the display industry. LTPS TFT allows for an easier IC manufacturing process and enhanced potential for integration. OLED provides the advantages of self-illumination, lower production costs, low power usage, wide viewing angles and rapid response time. OLED is touted as an important next-generation product following the reign of the liquid crystal display. ERSO has developed a near-transparent electrode material that makes it possible for light to emerge from the cathode side of a display, thus permitting displays with double-sided features. This technology is sure to be used in electronics products such as clamshell mobile phones.
In just five years, Taiwan's LCD display industry has expanded from the development stage of this technology to become the second largest display producer in the world. Some projections put Taiwan's display industry at the top of the world in 2005.
ITRI's
R&D efforts have been essential to the development of this industry.
Featuring low power consumption and high brightness, AMOLED is already being used in small products, such as cell phones, personal digital assistants (PDA), small TVs, tablet PCs and car display panels. While the current technology permits monochromatic displays,
ITRI is currently pursuing the development of color versions.
