Abstract:

A method and product for reducing reflected light glare into a humans eyes from the humans cheeks while simultaneously providing a non-verbal communication to others is provided, especially for use by participants in athletic contests. Underneath the humans eyes on the cheeks at a reflective location on the cheeks at which incident direct or indirect light is likely to be reflected into a humans eyes a non-toxic, non-reflective colored and finished material in the form of a predefined clearly demarcated geometric shape is applied. Within a week after the application (typically within less than a few hours after the athletic contest is over) the non-reflective material is removed. The non-reflective material may comprise eye black, applied using a stencil, or it may comprise a temporary tattoo or decal, applied in the conventional manner. The shape preferably is a sports apparel or equipment manufacturers or distributors logo and/or letters, or a team name, mascot or logo. The material is preferably black or dark colored, and any non-black or non-dark colored portions providing demarcation between elements of the shape comprises a dull or matte color having a wavelength of greater than about 650 nm and less than about 470 nm.

H01J 314

US Classification:

250216, 345 48

Abstract:

An illumination system for selectively illuminating a nonemissive electronic display comprises display elements in communication with at least one light source. The system comprises an nonemissive electronic display comprising a substrate having a first and a second surface, nonemissive display media having electrically responsive optical properties disposed on the first surface of the substrate, and a light transmissive element adjacent the second surface of the substrate. Light transmitted through the light transmissive element illuminates the display media. The invention also provides a tiled display comprising a plurality of substrates which can be selectively illuminated. The display elements can be tiled to create complex, selectively illuminated, three-dimensional display structures.

Abstract:

Disclosed herein are novel electrophoretic displays and materials useful in fabricating such displays. In particular, novel encapsulated displays are disclosed. Particles encapsulated therein are dispersed within a suspending, or electrophoretic, fluid. This fluid may be a mixture of two or more fluids or may be a single fluid. The displays may further comprise particles dispersed in a suspending fluid, wherein the particles contain a liquid. In either case, the suspending fluid may have a density or refractive index substantially matched to that of the particles dispersed therein. Finally, also disclosed herein are electro-osmotic displays. These displays comprise at least one capsule containing either a cellulosic or gel-like internal phase and a liquid phase, or containing two or more immiscible fluids. Application of electric fields to any of the electrophoretic displays described herein affects an optical property of the display.

US Classification:

345107, 359296, 359297

Abstract:

Novel addressing schemes for controlling electronically addressable displays include a scheme for rear-addressing displays, which allows for in-plane switching of the display material. Other schemes include a rear-addressing scheme which uses a retroreflecting surface to enable greater viewing angle and contrast. Another scheme includes an electrode structure that facilitates manufacture and control of a color display. Another electrode structure facilitates addressing a display using an electrostatic stylus. Methods of using the disclosed electrode structures are also disclosed. Another scheme includes devices combining display materials with silicon transistor addressing structures.

International Classification:

US Classification:

359296, 345107, 204450, 204606

Abstract:

Electrophoretic displays include a light-emitting layer, a photoconductive layer, and an electrophoretic layer. The light-emitting layer may be an organic, light-emitting material, or organic, light-emitting diode, which is addressable using a multiplex addressing drive scheme. The impedance of the photoconductive layer is lowered when struck by light from the light-emitting layer. As a result of the lowered impedance of the photoconductive layer, the electrophoretic layer, which itself cannot be multiplexed, is addressed at a lower, subthreshold voltage.

US Classification:

Abstract:

A process for creating an electronically addressable display includes multiple printing operations, similar to a multi-color process in conventional screen printing. In some of the process steps, electrically non-active inks are printed onto areas of the receiving substrate, and in other steps, electrically active inks are printed onto different areas of the substrate. The printed display can be used in a variety of applications. This display can be used as an indicator by changing state of the display after a certain time has elapsed, or when a certain pressure, thermal, radiative, moisture, acoustic, inclination, pH, or other threshold is passed. In one embodiment, the display is incorporated into a battery indicator. A sticker display is described. The sticker is adhesive backed and may then be applied to a surface to create a functional information display unit.

Abstract:

A display system includes a substrate upon which the display system is fabricated; a printable electrooptic display material, such as a microencapsulated electrophoretic suspension; electrodes (typically based on a transparent, conductive ink) arranged in an intersecting pattern to allow specific elements or regions of the display material to be addressed; insulating layers, as necessary, deposited by printing; and an array of nonlinear elements that facilitate matrix addressing. The nonlinear devices may include printed, particulate Schottky diodes, particulate PN diodes, particulate varistor material, silicon films formed by chemical reduction, or polymer semiconductor films. All elements of the display system may be deposited using a printing process.
