Titel
New method for head-up display realization by mean of chip on board and aerosol jet process
Abstract
A new method to fabricate transparent head-up display on glass has been developed. The method exploits the integration of the Aerosol JetĀ® Process in the Chip On Board technology. The Aerosol JetĀ® Process is an additive process, which allows the deposition of a wide variety of materials onto a wide variety of substrates without conventional masks or thin-film equipment, but driven by a CAD file (see, e.g. [1]). The process uses aerodynamic focusing to precisely and accurately deposit nano dispersions, so called "functional inks". The process has been used for the printing of thin conductive layout on glass with Agnanoparticle based conductive inks. After layout deposition, the chip-LED has been mounted on the glass by means of flip chip process exploiting micro-stamping technique. The developed displays have a luminance higher than 10000 cd/m2 and the visibility trough the glass substrate is fulfills requirements to guarantee the application also on windshield in automo tive field [2].
