Arizona State University successfully developed the first soft OLED display

The United States Arizona State University flexible display center (FDC) and Universal Display Corporation (UDC) announced that produced the first amorphous silicon flexible active matrix organic light emitting diode (OLED) display, this display is the use of DuPont Teijin (Dupont Teijin) PEN film production. And the use of UDC phosphor materials and FDC proprietary adhesive / de bonding (bond-debond) production technology. This 4.1 inch monochrome video graphics array (QVGA) represents a milestone towards the realization of flexible organic light emitting diode (OLED) display manufacturing solutions.

The main goal of the design of flexible OLED displays is the need for more robust and durable displays for some military and commercial applications. Using UDC PHOLED technology and materials, the new monitor has a very low power consumption, and can reach the same brightness as the traditional display. Additional technical advantages include a lower temperature, easier to drive, longer battery life, and more stable transistors due to less heat generation.

"The development of this soft active organic light emitting display provides a solid starting point for industrial manufacturing, mass production and commercialization of flexible organic light emitting diodes," said FDC engineering director Shawn O''Rourke.

In the flexible display center (FDC), the fabrication of the soft back panel display is made using a 180 C thin film transistor process. And the use of traditional flat-panel and semiconductor tools and processes to make displays, in addition, FDC also uses its proprietary adhesive / adhesive (bond-debond), to ensure that the operation of the manufacturing process, the plastic substrate is fixed.

P optical activity of organic light emitting diode integrated Universal Display Corporation (PHOLED) of the front plate technology provides key technology. The PHOLED material enables the OLED to convert up to one hundred percent of the energy into the illuminant, instead of the traditional fluorescent organic light emitting diode to convert only up to twenty-five percent, providing up to 4 times the efficiency of energy use.
