Abstract:
Each of a pair of spaced glass insulating substrate components has a plurality of mutually isolated conductive electrode layers on a surface thereof. Each surface faces the other and each plurality of electrode layers face the other. A layer of insulating material is applied to cover the electrode layers on each surface. A plurality of spaces are etched in a second layer of insulating material. The second layer is positioned between and joins the first layers of insulating material with the spaces between such layers sealed air tight, so that ionizable gas fills the spaces.
Abstract:
An improved gaseous discharge display arrangement is disclosed for providing a gray scale display capability with nominal modification of existing gaseous display apparatus. Conductor patterns of different resolution are utilized in the conductor drive configurations which are positioned on opposite sides of the panel in a conventional gaseous panel construction. By controlling the selective energization of the higher resolution lines associated with one of the driving configurations, a variation of intensities is provided depending on the ratio of the resolutions and the number of higher resolution conductors selected for each of the lower resolution conductors.
Abstract:
A pair of insulating substrates are positioned in spaced parallel relation having inside surfaces opposite each other with a gap filled with gas capable of ionization. A first group of electrodes are positioned on the inside surfaces of one of the substrates, and a second group of electrodes are positioned on the inside surfaces of the other of the substrates. The first group of electrodes are positioned in rows and the second group of electrodes are positioned in columns, and the first and second groups of electrodes are transversely positioned relative to each other. The surfaces of the first and second groups of electrodes are covered with dielectric layers, and each of the dielectric layers is covered with a protective layer to protect the surfaces inside the display device from sputtering. Each cross point of an electrode of the first group and an electrode of the second group is a discharge point for display.
Abstract:
Disclosed is a method for measuring luminance of each of entire pixels two-dimensionally arranged in a light-emitting display panel at regular intervals, using an image sensor in which light receiving elements are two-dimensionally arranged at regular intervals, the method including: providing an optical lens between the light-emitting display panel and the image sensor, and adjusting distances between the light-emitting display panel, the image sensor, and the optical lens by setting intervals of images of the entire pixels to be N times as large as intervals of the light receiving pixels, where N is a natural number, the images being to be formed on a light receiving surface of the image sensor through the optical lens; displaying, on the light-emitting display panel, a display pattern in which predetermined pixels from among the entire pixels produce a luminescence; and measuring the luminance of the predetermined pixels, using the light receiving elements.
Abstract:
A preferred embodiment microplasma device includes first and second substrates. An electrode array is disposed on the first substrate. Cavities are formed in the second substrate by laser micromachining, etching, or by chemical (wet or dry) etching and the second substrate is overlaid on the electrode array. The inter-electrode spacing and electrode width are set so that each cavity has at least one pair of electrodes underneath it to excite a microplasma discharge in the cavity. A need to precisely register the two substrates is avoided.
Abstract:
A fiber-based PALC (plasma addressed liquid crystal) display device includes two plates sandwiched around a top fiber array and a bottom fiber array. The top and bottom fiber arrays are substantially orthogonal and define a structure of the display, with the top fiber array disposed on a side facing towards a viewer. The top array includes three alternating top fibers, each top fiber including at least one wire address electrode and built in liquid crystal spacers. The top fibers are composed of a colored material with absorbing sides, which builds into the display the color filter and black matrix functions. The bottom array includes identical bottom fibers, each bottom fiber including a hollow plasma channel and two wire channel electrodes. Polarizing films and liquid crystal alignment layers are applied to the top and bottom fibers, which are assembled orthogonal to each other and a liquid crystal material is filled between them. The PALC display is sealed around the perimeter to contain the liquid crystal and the wire electrodes are brought out through the seal and connected to the drive control system.
Abstract:
A full color fiber plasma display device includes two glass plates sandwiched around a top fiber array and a bottom fiber array. The top and bottom fiber arrays are substantially orthogonal and define a structure of the display, with the top fiber array disposed on a side facing towards a viewer. The top fiber array includes identical top fibers, each top fiber including two sustain electrodes located near a surface of the top fiber on a side facing away from the viewer. A thin dielectric layer separates the sustain electrodes from the plasma channel formed by a bottom fiber array. The bottom fiber array includes three alternating bottom fibers, each bottom fiber including a pair of barrier ribs that define the plasma channel, an address electrode located near a surface of the plasma channel, and a phosphor layer coating on the surface of the plasma channel, wherein a luminescent color of the phosphor coating in each of the three alternating bottom fibers represents a subpixel color of the plasma display. Each subpixel is formed by a crossing of one top fiber and one corresponding bottom fiber. The plasma display is hermetically sealed with a glass frit. The sustain and address electrodes are brought out through the glass frit for direct connection to a drive control system.
Abstract:
A gas discharge illumination device is prepared by encapsulating ionizable gas within microporous or nanoscale sealed cavities created within a matrix material. Upon exposure of said matrix material to an electric field, the ionizable gas becomes ionized and emits light. By incorporating several different ionizable gases into one matrix material, a display with different colors of light can be produced. The gas discharge illumination device can be fabricated by a variety of techniques including selective cavity formation with overcoating taking place in an ionizable gas ambient, and bubbling ionizable gas through the matrix material while it is in viscous form. The gas discharge illumination device can be used to form either active or passive displays, as a sensor for detecting electric fields, and in other applications.

Thus, stable memory operation becomes possible.
