“…[24], [62], [107]- [114] As demonstrated at several Society for Information Display (SID) conferences, lightweight and flexible displays have become commercially successful. [115]- [118] Though usually not classified as a display, a colorimetric sensor resembles a display, [119] especially when it conveys easily intelligible combinatoric information. It thus qualifies as a (typically) one-time use display, often implemented on paper or other low-cost substrates.…”

Printed light sources, imaging systems and displays have revolutionized modern lifestyle by enriching visual feedback of various devices that human beings interact with. Despite the overall vastness of the field, there have been few to no attempts to place recent progress in these systems in sensor systems. In this short topical review, we survey the current state of art in printed light sources, imaging systems and displays specifically geared towards sensor applications. We find that the definition of displays needs to generalized in light of the availability of disposable colorimetric sensors for various chemical and biological markers. Recent exemplars of progress in each identified area are briefly presented and in conclusion, an overall view of the trends represented by these achievements is discussed.

“…The flexible glass substrate is dimensionally stable to enable required layer-tolayer alignment, while also displaying low scattering, haze, and absorption. The flexible glass substrate has been demonstrated to be compatible with roll-to-roll and sheet-level coating, lamination, printing processes, as well as stacked multilayer devices with low parallax [23,28].…”

A holographic device characterised by a large angular range of operation is under development. The aim of this study is to increase the angular working range of the diffractive lens by stacking three layers of high efficiency optical elements on top of each other so that light is collected (and focussed) from a broader range of angles. The angular range of each individual lens element is important, and work has already been done in an acrylamide-based photosensitive polymer to broaden the angular range of individual elements using holographic recording at a low spatial frequency. This paper reports new results on the angular selectivity of stacked diffractive lenses. A working range of 12° is achieved. The diffractive focussing elements were recorded holographically with a central spatial frequency of 300 l/mm using exposure energy of 60 mJ/cm2at a range of recording angles. At this spatial frequency with layers of thickness 50 ± 5 µm, a diffraction efficiency of 80% and 50% was achieved in the single lens element and combined device, respectively. The optical recording process and the properties of the multilayer structure are described and discussed. Holographic recording of a single lens element is also successfully demonstrated on a flexible glass substrate (Corning(R) Willow(R) Glass) for the first time.

“…By demonstrating that full-color LEDs can be fabricated on amorphous substrates, we suggest that since sputtering is very frequently used in the LCD industry, it is an established process that could be adapted to fabricate large-area inorganic LED displays on glass substrates. It should also be noted that state-of-the-art technology in the glass industry can offer roll-to-roll processing of flexible glass foils 24 . We think the combination of these techniques can lead to the development of large-area flexible inorganic devices.…”

InGaN-based light-emitting diodes (LEDs) have been widely accepted as highly efficient light sources capable of replacing incandescent bulbs. However, applications of InGaN LEDs are limited to small devices because their fabrication process involves expensive epitaxial growth of InGaN by metalorganic vapor phase epitaxy on single-crystal wafers. If we can utilize a low-cost epitaxial growth process, such as sputtering on large-area substrates, we can fabricate large-area InGaN light-emitting displays. Here, we report the growth of GaN (0001) and InGaN (0001) films on amorphous SiO2 by pulsed sputtering deposition. We found that using multilayer graphene buffer layers allows the growth of highly c-axis-oriented GaN films even on amorphous substrates. We fabricated red, green, and blue InGaN LEDs and confirmed their successful operation. This successful fabrication of full-color InGaN LEDs on amorphous substrates by sputtering indicates that the technique is quite promising for future large-area light-emitting displays on amorphous substrates.
