High Luminescence In Cockpit

Project description

Screen innovations to meet demand for high-quality information displays

Today’s display technologies, particularly in commercial avionics, have not achieved the required brightness to provide readable information, consume too much power and are not compact enough. To address these issues, the EU-funded HiLICo project aims to develop, test and validate LED-based micro-display technology that will lead to a compact, transparent system for future avionics applications. Introducing novel products to the micro-display industry and to the health applications field, including head-mounted displays and smart eyewear, will boost European competitiveness. The new technology will also have environmental and aircraft safety benefits.


Although the market demand of displays bright enough to allow the diffusion of readable information against a very bright landscape is important, in particular in the avionics application, existing technologies still do not allow the desired brightness combined with very low power consumption and very compact volume.
In this context, the HiLICo project aims at developing a new generation of monochrome and full-color emissive GaN micro-displays with 1920 x 1200 pixel resolution (WUXGA), 8-μm pixel pitch, very high brightness (over 1MCd/cm²) and good form factor capabilities that will enable the design of ground breaking compact see-through system for next generation Avionics applications.
To achieve this aim, HiLICo will address the following challenges:
1. development of high-quality GaN based LED epilayers designed to fulfill targeted demonstrator performances;
2. design and fabrication of an active matrix in advanced Complementary metal oxide semi-conductor (CMOS) technology to control each individual pixel;
3. coupling of the LED structure and the CMOS, building a monolithic structure on which LED arrays will be fabricated with high precision, thus making monochrome, active-matrix, high-resolution GaN microdisplays;
4. addition of colour converters (quantum dots and 2D Multi-Quantum Wells layers) on such blue emitting devices, for fabricating bi-color and full-color display demonstrators;
5. design and manufacture of the electronics followed by the test and evaluation of the complete micro display device. First demonstrators will be qualified for future commercialisation.
The technology developed will contribute to the increase of European competitiveness, through the rapid and important deployment of innovative products on the microdisplay market, as well as Head-Up Displays, Head-mounted displays and smart Eyewears.
The consortium gathers 1 RTO, 1 large company and 2 SMEs. They will mobilise a grant of 4 091 583 € with an effort of 283 PM.
