Abstract:
An electronic display is formed using an array of hollow tubes filled with an electrophoretic material sandwiched between two plates. The hollow tubes have either barrier walls or an electrostatic barrier, which restrict the flow of electrophoretic particles within the hollow tubes. The flow of electrophoretic particles over these barriers is controlled using electric fields, which makes it possible to matrix address the electrophoretic displays. Wire electrodes built into the hollow tubes and electrodes on the two plates are used to address the display. The plates are preferably composed of glass, glass-ceramic, polymer/plastic or metal, while the hollow tubes are preferably composed of glass, polymer/plastic or a combination of glass and polymer/plastic. Color is optionally imparted into the display using colored tubes, adding a color coating to the surface of the tubes, or adding the color to the electrophoretic material. Reflectivity within the display is accomplished by using a reflective material to fabricate the tubes, coating the tubes with a reflective material or coating one of the two plates with a reflective material. The display can also function in a transmissive mode by applying an illuminating back to the display.
Abstract:
An assembly of rib structures sandwiched between a dielectric glass layer and a glass substrate for use in a flat panel display, such as plasma addressed liquid crystal (PALC) displays, is formed by a number of methods. One method includes molding thermoplastic glass frit containing paste into rib structures, transferring the rib structures to a thin transparent layer of a thermoplastic dielectric glass frit containing composition on a drum, and transferring the rib structures with the thin transparent dielectric glass layer to a glass substrate having metallic electrodes already formed thereon.
Abstract:
The invention relates to a field emission display constructed using an array of fibers and an orthogonal array of emitter electrodes. Each fiber in the fiber array contains an extraction electrode, spacer, a high voltage electrode and a phosphor layer. The array of emitter electrodes consists of carbon nanotube emitters attached to conductive electrodes. The emitter electrodes are separated using non-conductive fibers. A getter material in the form of a wire is placed within the array of emitter electrodes to maintain a high vacuum within the display.
Abstract:
Plasma channels in a PALC display have a minimal width, which implies that substantially all light passes via optically planar surfaces so that depolarization is prevented. The small width also enhances the extinction rate of the plasma so that less critical gas mixtures may be used. In a specific embodiment, the microsheet may be dispensed with.
Abstract:
Plasma addressed liquid crystal display ribs are produced by introducing a glass paste which includes a curable medium into cavities formed in an intaglio collector to define rib structures, which are transferred from the collector to a surface of a substrate, and removing the curable medium from the rib structures on the substrate surface to generate pores in the rib structures. The substrate having rib structures is then dipped into a solution containing an opaque pigment which is absorbed into the rib structure. Alternatively, ribs are produced by forming a temporary mask on portions of a surface of a substrate, depositing a layer of a glass paste having a curable medium and at least one pigment blended therein over the substrate and temporary mask, micro-molding rib structures from the glass paste on the substrate surface in areas between the masked sections, removing any residual layer of paste material present on the temporary mask, removing the temporary mask from the substrate, and firing the substrate with micro-molded rib structures thereon.
Abstract:
A display device comprising channels (30, 30′, 30″) containing an ionizable gas (33), and walls of the channels (30, 30′, 30″) being provided with row electrodes (31, 32) for selectively ionizing the ionizable gas (33) during operation. The display device is further provided with an electro-optical layer (35) and means for activating said electro-optical layer (35). The display device is characterized in that the ionizable gas (33) contains a carrier gas and an additional gas, said additional gas comprising deuterium or deuterium hydrogen, or hydrogen and a further gas having a higher molecular weight. Preferably, helium or nitrogen is used as the carrier gas, and the additional gas comprises deuterium or deuterium hydrogen, or hydrogen and nitrogen, or hydrogen and xenon.
Abstract:
A channel plate suitable for use in a plasma-addressed electro-optic display device and comprising a substrate having a set of elongate channels formed therein covered by a thin deposited dielectric layer is fabricated by filling the channels with filler material, depositing a layer of porous dielectric material over the substrate, removing the filler material from the channels through the porous layer and thereafter depositing a layer of non-porous dielectric material over the porous layer so as to close the channels. In this way a very thin dielectric layer can reliably be provided which improves operation of the channel plate as an addressing structure, with the channels filled with an ionisable gas, for example in a display device having electro-optic material overlying the dielectric layer.
Abstract:
A process for frit-sealing together a panel of a fiber-based information display includes assembling the panel and sealing, after the step of assembling, the panel by forcing a glass frit to flow between the two glass plates that comprise the panel using narrow strips of glass. The glass frit-seals the top and bottom glass plates together and covers the wire electrodes at the end of the fibers to dielectrically isolate them from each other. The process of assembling and frit-sealing the panel is particularly suitable for use in an information display, such as plasma emissive displays, plasma addressed liquid crystal displays, and field emissive displays.
Abstract:
A method of manufacturing a plasma display panel, which comprises the steps of filling a barrier rib-forming paste containing glass frit in a barrier ribs-forming intaglio and concurrently forming a paste layer having a constant thickness on the intaglio, superimposing a substrate on the barrier ribs-forming intaglio filled with the barrier rib-forming paste containing glass frit to thereby transfer the barrier rib-forming paste onto the substrate, and heating the barrier rib-forming paste that has been transferred to the substrate, thereby burning out existing organic components and concurrently sintering the glass frit to thereby form the barrier ribs and dielectric layer. The plasma display panel manufactured by this method is featured in that the barrier ribs and the dielectric layer are formed using the same barrier rib-forming material containing a low melting point glass frit.
