Description du projet
Des écrans innovants pour répondre à la demande d’écrans d’information de haute qualité
Les technologies d’affichage actuelles, en particulier dans l’avionique commerciale, n’offrent pas la luminosité nécessaire pour fournir des informations lisibles, sont trop gourmandes en énergie et trop peu compactes. Pour résoudre ces problèmes, le projet HiLICo, financé par l’UE, entend développer, tester et valider une technologie de micro-affichage à base de LED qui débouchera sur un système compact et transparent pour de futures applications avioniques. L’introduction de nouveaux produits dans l’industrie des micro-écrans et dans le domaine des applications de santé, notamment les visiocasques et les lunettes intelligentes, renforcera la compétitivité de l’Europe. Cette nouvelle technologie profitera également à l’environnement et à la sécurité des avions.
Objectif
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.
