    摘要： A tiled display device is formed from display tiles having picture element (pixel) positions defined up to the edge of the tiles. Each pixel position has an organic light-emitting diode (OLED) active area which occupies approximately 25 percent of the pixel area. Each tile includes a memory which stores display data, and pixel driving circuitry which controls the scanning and illumination of the pixels on the tile. The pixel driving circuitry is located on the back side of the tile and connections to pixel electrodes on the front side of the tile are made by vias which pass through portions of selected ones of the pixel areas which are not occupied by the active pixel material. The tiles are to formed in two parts, an electronics section and a display section. Each of these parts includes connecting pads which cover several pixel positions. Each connecting pad makes an electrical connection to only one row electrode or column electrode. The connecting pads on the display section are electrically connected and physically joined to corresponding connecting pads on the electronics section to form a complete tile. Each tile has a glass substrate on the front of the tile. Black matrix lines are formed on the front of the glass substrate and the tiles are joined by mullions which have the same appearance as the black-matrix lines. Alternatively, the black matrix lines may be formed on the inside surface of an optical integrating plate and the tiles may be affixed to the integrating plate such that the edges of the joined tiles are covered by the black-matrix lines. A cathodoluminescent tile structure is formed from individual tiles that have multiple phosphor areas, a single emissive cathode and horizontal and vertical electrostatic deflecting grids which deflect the electron beam produced by the single cathode onto multiple ones of the phosphor areas.

    摘要： A display device having features which enhance the contrast of displayed images includes a pixel structure that defines an active pixel area and an inactive pixel area. The display device may be an emissive device such as an OLED or electroluminescent device, a transmissive device such as a liquid crystal light-valve device or a reflective device, such as a Bistable, Reflective Cholesteric (BRC) liquid crystal device. The ratio of the active pixel area to the total pixel area is less than 50 percent. The display device includes a transparent cover plate having a black matrix formed on the viewer side of the cover plate. The display device may be a tiled display in which case the black matrix is formed on an integrator plate to which the individual tiles are bound to form the complete display device. For reflective or emissive display materials, the display device includes an electronics section including a circuit board which provides driving signals for the pixels of the display device. The electronics section is bound to the display section by an adhesive. To provide a light-absorptive background for the active pixel elements, the circuit board or the adhesive are colored black. The individual pixel elements of the display device include four sub-pixel components separated by portions of the inactive pixel area, which four sub-pixel components together define the active area of the pixel. A lens system is provided on the viewer surface of the display to concentrate light emitted by the active area of the pixel elements into a smaller area, thus decreasing the aperture of the display. Areas between the lenses on the viewer surface of the display are coated with a black material to form a black matrix. A black material is selectively deposited on the front cover plate before applying the metal row electrodes to prevent the row electrodes from providing a reflective surface to the viewer.

    摘要： A method and associated system that compensates for long-term variations in the light-emitting efficiency of individual organic light emitting diodes (OLEDs) in an OLED display device, calculates and predicts the decay in light output efficiency of each pixel based on the accumulated drive current applied to the pixel and derives a correction coefficient that is applied to the next drive current for each pixel. In one exemplary embodiment of the invention, the calculation is based the accumulated current that has been passed through the device. In another exemplary embodiment, the calculation is based on a difference in voltage across the pixel at two instants. The compensation system is best used after the display device has been calibrated to provide uniform light output. The present invention further provides a method for calibrating a display device comprising an array of individually adjustable discrete light emitting devices (pixels) using a camera having an array of radiation sensors or a single photodetector. According to this method, the camera captures respective images of substantially equal-sized first sub-areas and adjusts the driving current for each of said pixels within said first sub-areas to achieve a desired light output. Next, the camera captures images of a plurality of second sub-areas, each of the second sub-areas including multiple ones of the first sub-areas second-level sub-areas are adjusted such that each of the first-level sub areas provide substantially equal light output. In an alternative embodiment, each of the first level sub-areas overlaps and, after adjusting a first sub-area to a desired brightness level, the invention adjusts the pixels in each overlapping sub-area to have the same brightness as the overlapping pixels.

    摘要： A plasma display includes a front panel having a glass body secured to a surface of a substrate. The glass body has a plurality of channels in the exposed surface thereof with upstanding ribs being between the channels. Conductive first electrodes are on the body with each electrode extending along the bottom of a separate channel. The first electrodes are preferably embedded in the glass body. A transparent front panel is over the back panel and is seated on and secured to the glass body. A plurality of spaced, parallel second electrodes extend between the front panel and the back panel substantially orthogonally to the first electrodes. Phosphors which emit different colors are coated on the channels and the channels are filled with a plasma gas. The back panel is formed of at least one and preferably a plurality of layers of a green tape of glass particles in a binder. The layers are stacked one on top of each other and the channels are formed in the surface of one of the layers. The stack is placed on a substrate and fired to bond the layers together and to the substrate.

According to one aspect of the invention, the first layer of the electrode structure is designed to provide electrical contact to a fluid electronic material and the second layer of the electrode structure is formed so as to constrain the fluid electronic material in a precise pattern. Alternatively, the second layer of the two-layer electrode structure includes a low surface energy material to further assist in constraining the fluid electronic material to the desired pattern. In another alternative, the first layer of the electrode structure includes a transparent electrode material, that is coupled to an electro-optical device. The second layer of this electrode structure includes a high conductivity material that is coupled to the first layer of the electrode structure in an area not directly over the electro-optical device to improve the conductivity of the transparent electrode structure.
