Holst and imec explore next-gen OLED

Holst Centre and imec has launched a new research program on next-generation flexible OLED (organic light emitting diode) displays, which aims to develop an economically scalable route to high-volume manufacturing of flexible active-matrix OLED displays. The shared program tackles challenges such as high resolution, low power consumption, large area, outdoor readability, flexibility and light weight.

OLED displays are small and mobile, and currently used in smartphones and tablet PCs. They are characterized by a strong contrast compared to conventional LCDs since OLED pixels emit only when activated, achieving a more intense black. Moreover, OLEDs have a faster response time, eliminating image lag. They also consume less power while providing better contrast and viewing angle than conventional LCDs. OLEDs are also simpler in design and contain less components enabling substantial process cost reductions.

The program aims to work towards flexible, high-resolution OLED displays, and tackle challenges such as: a mechanically flexible encapsulation film and TFT backplane; and printed, high-efficiency OLEDs. New materials and processes that allow for cheaper production, better quality, lower power, more robustness and flexibility will be developed. Moreover, the design of the drivers, pixel circuits and TFT backplane matrix will be reconsidered as increasing display area influences the amount of pixels-per-inch or the refresh rates. Finally, the program scope includes the development of new manufacturing equipment such as fine patterning equipment for backplanes and tools for integrated roll-to-roll manufacturing.

Gerwin Gelinck, program manager, OLED display program, Holst Centre ”Holst Centre and its partners continuously look for new application domains for the generic flexible electronic technologies that have been developed. Flexible displays represent an enormous economic and technical opportunity for flat panel manufacturers and its supply chain. As such they are seen as an attractive landing place for many new technologies. Flexible displays are therefore becoming a top priority research effort for many companies worldwide, including many of our current industrial partners.”
