Consortium looks to 3D OLED displays

CRL Opto has been selected to lead a consortium involving Thomson, CEA, DSM and the University of Hull to develop novel photopatternable light emitting polymer OLED-on-silicon displays.

CRL Opto has been selected to lead a consortium involving Thomson, CEA, DSM and the University of Hull to develop novel photopatternable light emitting polymer OLED-on-silicon displays.

This collaborative project, known as Photoledd, started in January 2003 and is supported by the European Commission.

Emissive displays based on organic light emitting diodes (OLEDs) are considered by the displays industry to be a very promising technology: present predictions suggest a market value of $3 billion by 2007.

As demand increases for displays with dual 2D and 3D image capabilities in a wide range of applications, an effective low cost manufacturing route for these high performance emissive displays will be required.

The Photoledd consortium aims to provide this technology.

The primary aim of this project is to demonstrate that economic manufacture of both 2D and 3D direct-view and miniature OLED displays can be made through the development of novel photopatternable organic light emitting diodes (p-OLEDs), RGB emitter materials and related manufacturing processes.

The photopatternability of the new p-OLED materials allows conventional photolithography techniques to be employed so that high-resolution colour displays can be manufactured using fewer processing steps than colour filter based active matrix displays.

Colour will be generated by a colour conversion technique based on a blue emitter.

The development of the unique stereoscopic 3D displays will use a concept jointly patented by CRL Opto and Hull University based on the emission of polarised light from an OLED device.

The project's main aims are to: demonstrate a stereoscopic 3D binocular display system based on a single OLED display; and devise a cost effective photopatternable process for the fabrication of both 2D and 3D displays for applications in direct view displays and microdisplays - paving the way for the volume manufacture of low-cost low-power OLED displays.

Photoledd is funded by the Information Society Technologies (IST) Initiative, part of the European Union's 5th Framework Programme with special emphasis for the development of innovative technologies, products and services for the new information age.
