Abstract:
An electroluminescent display device contains an electroluminescent phosphor (140) sandwiched between a pair of electrodes (120, 220) and a graphic arts element (260). The device is fabricated by bonding a generic electroluminescent base laminate (100) containing an electrode (120) and an electroluminescent layer (140), to a custom graphic arts film (200) containing a graphic element (260) and a corresponding electrode (220). The generic electroluminescent base laminate is made at a first location or time, and the custom graphic arts film is made at a second location or time.
Abstract:
In a printed electronic device and methods for determining the electrical value of the device, a dielectric material 130 is contact printed on a substrate 110 using a preset force. The substrate 110 has a pressure sensitive material 120 that is optically responsive in direct proportion to the amount of force imparted by the contact printing. The force of the contact printing causes the pressure sensitive material to form a pattern that is quantifiable to the amount of feree. The pattern is then optically inspected and compared to sets of standards in order to quantify the amount of feree that was used in printing. The thickness of the printed dielectric material is then calculated based on the quantified force by comparing to another set of standards.
Abstract:
A printing platform receives (102) (preferably in-line with a semiconductor device printing process (101)) a substrate having at least one semiconductor device printed thereon and further having a test structure printed thereon, which test structure comprises at least one printed semiconductor layer. These teachings then provide for the automatic testing (103) of the test structure with respect to at least one static (i.e., relatively unchanging) electrical characteristic metric. The static electrical characteristic metric (or metrics) of choice will likely vary with the application setting but can include, for example, a measure of electrical resistance, a measure of electrical reactance, and/or a measure of electrical continuity. Optionally (though preferably) the semiconductor device printing process itself is then adjusted (105) as a function, at least in part, of this metric.
Abstract:
A power source (201) and a printed transistor circuit (202) are combined with one another in a stacked and integral configuration. In a preferred though optional configuration this combination can further comprise a substrate (200) of choice. The power source can comprise a technology of choice such as, but not limited, to, a battery or a photovoltaic element. These elements can be combined (104) using a joining technology of choice such as, but not limited to, laminating these elements together or printing one upon the other.
Abstract:
Data regarding printing instructions for an active electronic component are provided (11). These printing instructions will typically comprise instructions regarding the location, geometry, size, orientation, and functional inks used for various component layers as correspond to the electronic component, and are without reference to a specific printing system. This data is then modified (12) as a function of one or more operational proclivities of a particular high throughput additive printing system to provide modified instructions that, when employed to effect the printing of the active electronic component, will improve the resultant yield as compared to the unmodified data.
Abstract:
An apparatus (200) such as a semiconductor device comprises a gate electrode (201) and at least a first electrode (202). The first electrode preferably has an established perimeter that at least partially overlaps with respect to the gate electrode to thereby form a corresponding transistor channel. In a preferred approach the first electrode has a surface area that is reduced notwithstanding the aforementioned established perimeter. This, in turn, aids in reducing any corresponding parasitic capacitance. This reduction in surface area may be accomplished, for example, by providing openings (203) through certain portions of the first electrode.
Abstract:
A low-temperature process for creating a semiconductive device by printing a liquid composition containing semiconducting nanoparticles. The semiconductive device is formed on a polymeric substrate (22) by printing a composition that contains nanoparticles of inorganic semiconductor suspended in a carrier, using a graphic arts printing method. The printed deposit is then heated to remove substantially all of the carrier from the printed deposit (25). The low-temperature process does not heat the substrate or the printed deposit above 300° C. The mobility of the resulting semiconductive device is between about 10 cm2/Vs and 200 cm2/Vs.
Abstract:
An electroluminescent display contains an array of dynamically addressable pixels. The pixels are arranged on one side of a carrier substrate. Conductive vias in the substrate are electrically connected to each of the pixels. Each pixel consists of a bottom electrode that is coupled to a via, an electroluminescent material, and a dielectric material. A common top electrode is disposed on the dielectric material. A driver circuit conductor or connector is situated on the other side of the substrate and is electrically coupled to each of the conductive vias and to the common top electrode, so that each pixel can be individually addressed to illuminate the electroluminescent material on individual pixels.

Merchandising and marketing data collection systems (100, 400, 500, 700, 1200, 1300, 1400, 1500) collect data on shopper's (816) interaction with merchandise samples (106, 414, 1212, 1400, 1502), page store personnel, output promotional vouchers and use the merchandise samples to access information about the capabilities of the merchandise being sold.
