“…Progress has continued in the field, resulting in devices with mobility values higher than 200cm 2 /Vs and the fabrication of functional digital circuits for the first time on metal foils [8,9]. From the application viewpoint, thin metal foils have been recently utilized in the fabrication of active-matrix a-Si TFT digital ink displays [10]. On this paper, we are presenting high-speed polycrystalline silicon thin film transistor digital circuits as well as all the elements needed for the fabrication of a display, representing some of the building blocks for such integrated systems.…”

This paper describes the development of a 3.5 inch diagonal Active Matrix Organic Light Emitting Diode Display on flexible metal foils. The active matrix array had the VGA format and was fabricated using the polysilicon TFT technology. The advantages that the metal foil substrates offer for flexible display applications will first be discussed, followed by a discussion on the multilayer coatings that were investigated in order to achieve a high quality insulating layer on the metal foil substrate prior to TFT fabrication. Then the polysilicon TFT device performance will be presented as a function of the polysilicon crystallization method. Both laser crystallized polysilicon and solid phased crystallized polysilicon films were investigated for the TFT device fabrication. Due to the opaque nature of the metal foil substrates the display had a top emission structure. Both small molecule and polymer based organic material were investigated for the display emissive part. The former were evaporated while the latter were applied by spin-cast. Various transparent multi-layer metal films were investigated as the top cathode. The approach used to package the finished AMOLED display in order to protect the organic layers from environmental degradation will be described. The display had integrated polysilicon TFT scan drivers consisting of shift registers and buffers but external data drivers. The driving approach of the display will be discussed in detail. The performance of the finished display will be discussed as a function of the various materials and fabrication processes that were investigated.

“…Companies such as Amazon, with its subsidiary LiquaVista, are developing on electro‐wetting [ 9 ] displays while Kent Displays and BMG MIS are developing cholesteric liquid crystals technologies. [ 10 ] Electrophoretic displays are mainly developed by the E‐ink company [ 11 ] and are integrated in some electronic books as the Kindle ebook. However, these non‐emissive technologies remain less prevalent on the market than emissive ones; indeed, they have not yet reached the technological maturity or are unable to reproduce all the color palettes, such as the electrophoretic devices, for example.…”

Color reproduction through subtractive synthesis is achieved by combining the three primary colors cyan, magenta, and yellow (CMY). Three CMY electroactive polymers are selected, synthesized, and first, integrated into monochromatic electrochromic devices (pixels) similar to electrochemical cells. In order to develop innovative trichromatic devices, new pixel architectures are proposed and compared. In particular, the stacking of the three monochromatic CMY electrochromic devices in a single system is declined in the form of three different electrochemical cells, which differ in the nature and positioning of the counter‐electrode. Overall performances are finally evaluated in terms of range and ease of assembly. The architecture with common counter‐electrode is clearly the one that offers the best potential for the development of electrochromic devices to reproduce a wide range of colors.

This paper discusses the design and fabrication of digital circuits (primarily shift registers) for display and other active‐matrix driving applications on flexible substrates. The unique advantages of the substrate material and their relation to circuit performance are indicated. A high temperature fabrication process for laser annealed polycrystalline silicon MOS transistors on stainless steel foils is outlined, resulting in effective mobility values up to 267cm2/Vs for n‐channel and 88cm2/Vs for p‐channel devices. Transistor CMOS inverters with a minimum propagation delay of 1.02ns per inverter stage are reported. Both static and dynamic register designs with a high degree of integration are reported, having maximum operating frequencies up to 1.5MHz and 2.5MHz respectively, at supply voltages of 10V or less. These results constitute the first realization of this level of performance and complexity on flexible substrates, and demonstrate the feasibility of high‐speed digital circuitry on thin foils suited for ‐ but not limited to‐ active matrix array driving.
