    Sensoren zijn een veelbelovende optie voor het beheersen en controleren van waterkwaliteit. Innovatie en implementatie van sensoren wordt momenteel belemmerd door onduidelijkheden over prestaties van sensoren en behoeften van gebruikers. Er wordt niet altijd onderscheid gemaakt tussen de verschillende toepassingsgebieden van sensoren, waardoor appels met peren worden vergeleken. Daarnaast zijn er onduidelijkheden over de implementatie van sensoren, bijvoorbeeld over hun acceptatie als wettelijk toegestane monitoringsmethode. In dit artikel stellen wij een indeling in vier hoofdrichtingen van sensortoepassingen voor als leidraad in discussies, en pleiten wij ervoor dat waterbedrijven, onderzoekers en ontwikkelaars ook drinkwaterlaboratoria, toezichthouders en beleidsmakers betrekken in die discussie

    AMOLED Displays with In-Pixel Photodetector

    Get PDF
    The focus of this chapter is to consider additional functionalities beyond the regular display function of an active matrix organic light-emitting diode (AMOLED) display. We will discuss how to improve the resolution of the array with OLED lithography pushing to AR/VR standards. Also, the chapter will give an insight into pixel design and layout with a strong focus on high resolution, enabling open areas in pixels for additional functionalities. An example of such additional functionalities would be to include a photodetector in pixel, requiring the need to include in-panel TFT readout at the peripherals of the full-display sensor array for applications such as finger and palmprint sensing

    Indium Gallium Zinc Oxide (IGZO) films are deposited using plasma-enhanced spatial Atomic Layer Deposition (sALD) on substrates as large as 32 cm x 35 cm. Excellent uniformity and thickness control leads to high-performing and stable co-planar top-gate self-aligned (SA) thin-film transistors (TFTs), demonstrating the viability of atmospheric spatial ALD as a novel deposition technique for the flat-panel display Industry

Excellent uniformity and thickness control leads to high-performing and stable coplanar top-gate self-aligned (SA) thin-film transistors (TFTs). The integration of a sALD-deposited aluminum oxide buffer layer into the TFT stack further improves uniformity and stability.
