“…1d) allows the complimentary colors to mix (overlap) and therefore create black, or the colors are removed from the pixel area they can reveal a white background. Pixel technologies that could work for mixing biprimary include electrophoretic (vertical [1] and horizontal in-plane [5], or combinations thereof such as elecrokinetic [6]). Other technologies such as liquid crystal or MEMs may also be capable of non-mixing or mixing bi-primary function, but currently lack the ability to so (e.g.…”

“…The monochrome Amazon Kindle and other e-readers using reflective displays have created an enormous buzz, a moment many researchers have been intensely pursuing in the past decade. The Kindle uses e-Ink™, which elegantly transposes (moves) charged white or black pigment particles toward or away from the front surface of the display [1]. However, in the eyes of some, the excitement over e-Paper has been dampened by the success of Tablet PC's such as the i-Pad.…”

A new bi-primary color system for doubling the reflectance and colorfulness of e-paper

There are several paradigms for color generation in reflective displays (e-Paper) including RGBW color filtering or stacked RGB or CMY. Theoretically, the highest white state reflectance and best color gamut are achieved by stacking three layers of pixels. However, stacking 3 layers induces significant optical losses especially at high resolution and typically does not allow for video operation. Therefore RGBW color filtering is currently preferred for higher resolution and single-layer e-Paper, but only provides color at 25% of the area and a maximum theoretical white reflectance of 50%. Presented herein is a new bi-primary color-system that cooperatively displays two complimentary colors inside a single sub-pixel, and therefore doubles the white state reflectance and color gamut for single-layer e-Paper. Also discussed are candidate e-Paper technologies that may be able to adopt the bi-primary color system, including possible advantages and challenges for each technology.

We present a transmissive-type interferometric display featuring a single layer of Fabry-Pé rot filter using blue phase liquid crystal (BPLC) in tandem with a quantum-dot backlight. With this design, no polarizers and color filters are needed. The intensity modulation is implemented by electrically controlling BPLC's Kerr effect, while the color modulation employs a sequential color scheme. Based on numerical simulations, device performance has been studied in depth. Index Terms-interferometric display, Fabry-Pé rot filter, blue phase liquid crystal, quantum dot.I.

“…While directly addressed (segmented) displays are sufficient for simple message signs, with active matrix addressing, arbitrary images can be displayed [27][28][29][30]. Large-area active matrix backplanes made by conventional lithography suffer from relatively high fixed (equipment-based) and variable (materials-based) cost, however.…”

IntroductionConventional methods for materials processing, such as thin-film deposition and photolithographic patterning provide the foundation for device fabrication in the microelectronics industry. Although these methods are scaleable and cost-effective, as demonstrated in the silicon integrated-circuit (IC) industry, they are not always the most appropriate methods for applications where further miniaturization is not an advantage, such as large-area electronics. Active-matrix liquid-crystal displays (AMLCD) [1], an industry that has grown to a $30 billion dollar business and X-ray imaging [2], another rapidly emerging application for thin-film transistor (TFT) devices are two examples of large-area electronics. Both of these applications rely on the ability to pattern transistor structures over large substrates. Particularly for AMLCD, the cost and difficulty of conventional patterning larger areas has slowed down the introduction of very large-format products. Many new materials systems, based on organic and polymeric semiconductors, are also rapidly being developed to address the intrinsic difficulties of large-area processing. Ideally, these materials are solution-processable, which can enable novel deposition and patterning processes such as jet printing for fabrication of TFT devices.While these polymeric materials hold promise for low-cost electronics and simplified device processing, they still suffer from lower performance than conventional inorganic semiconductors. As the development of these novel materials continues, an alternative technology incorporating patterning schemes such as inkjet printing and conventional vacuum deposited thin films, may provide the required overlap of performance with low-cost fabrication of microelectronic circuits on large-area platforms.In flat-panel display applications, manufacturers reduce production costs by increasing the mother-glass plate size, thus yielding more displays on a single plate of glass using a batch process. Figure 11.1 shows the trend for substrate size as a function of time with the current Generation 7 plate size having an area of 1.8 Â 2.2 m 2 . As the plate size increases in the coming years, it is unclear how Organic Electronics, Materials, Manufacturing and Applications. Edited by Hagen Klauk
