UPMOST - Ultrafast laser processing

To develop ultrafast laser processing for advanced mobile displays.

(2013-2018)

About the project:

UPMOST (Ultrafast laser Processing for MObile diSplay Technology) is devoted to the development of a non-thermal, ultra-precision machining process utilizing femtosecond lasers and novel optical systems for beam shaping and pulse shaping. The aim is to provide a fully customized fabrication mean for high resolution mobile displays as submicron precision is required as the pixel size of such HD displays decreases.

ALPhANOV's role:

Developing innovative processes to overcome the challenges posed by the complex multi-layered geometry of electronic screens, always smaller pixels and the use of sensitive organic materials. These developments aim to define the characteristic quantities of the laser / material interaction (ablation thresholds, material flow rate, penetration depth per pulse) for various materials, in particular, organic materials, used in the manufacture of electronic screens.
