Roll-to-roll manufacturing for small-molecule flexible OLED devices

Recentl y, several lighting companies in Europe and Asia have started pilot production of OLED devices on glass.


The OLED covers a range of applications from less demanding signage and decorative lighting up to large area flexible illumination, automotive applications and general lighting which have higher requirements in terms of efficiency and reliability. It is believed that the price can drop significantly by transferring the sheet-to-sheet fabrication into the roll-to-roll (R2R) processing. High throughput and the use of relatively cheap metal foil and plastic web as substrates will be the major cost reducing step. Aluminium foil already fulfils one important requirement as a substrate for OLEDs regarding impenetrability to water and oxygen.

The development platform for i.MX 6Quad from element14 (built to the Freescale SABRE Lite design) is an evaluation platform featuring the powerful i.MX 6Q, a multimedia application processor with Quad ARM Cortex-A9 cores at 1.2 GHz from Freescale Semiconductor.

This month, Freescale and element14 are giving away five such platforms, worth £128.06 each, for EETimes Europe's readers to win. The platform helps evaluate the rich set of peripherals and includes a 10/100/Gb Ethernet port, SATA-II, HDMI v1.4, LVDS, parallel RGB interface, touch screen interface, analog headphone/microphone, micro TF and SD card interface, USB, serial port, JTAG, camera interface, and input keys for Android. 


 

And the winners are...

In our previous reader offer, Pico Technology was giving away one of its recently launched PicoScope 3207B, a 2-channel USB 3.0 oscilloscope worth 1451 Euros. Lucky winner Mr L. Sanchez-Gonzalez from Spain should be receiving his PicoScope 3207B soon. Let's wish them some interesting findings with his projects.
