Abstract: An electrical assembly (200, FIG. 2) is formed from two, interconnected circuit boards (202, 204). Conductive spacers (240) and a conductive material (260) are placed between complementary bond pads (218, 232) on the circuit boards. The conductive spacers are formed from a material that maintains its mechanical integrity during the process of attaching the circuit boards. The conductive material is a solder or conductive adhesive used to mechanically attach the circuit boards. In addition, an insulating material (270) is inserted into an interface region (250) between the circuit boards. The insulating material provides additional mechanical connection between the circuit boards. In one embodiment, one circuit board (202) includes a glass panel that holds an array of organic light emitting diodes (OLEDs), and the other circuit board (204) is a ceramic circuit board. Together, the interconnected circuit board assembly (200) forms a portion of a flat panel display (1102, FIG. 11).

Abstract: A display panel is structured for attachment of multiple circuits using a two-dimensional array of contacts. Components, constituting driver circuits, can be mounted to the back of the panel in a central region of the panel rather than at the edges thereof.

Abstract: A way of driving emissive displays is provided. An apparatus comprises a first panel having one or more contacts in a pre-selected arrangement. The apparatus comprises a display panel having one or more light emitting elements and one or more contacts in the pre-selected arrangement to deliver current to the light emitting elements, wherein the contacts of the display panel are surface mounted to the contacts of the first panel.

Abstract: Briefly, this is a disclosure of embodiments of a technique, an apparatus, and a system for luminance compensation for emissive displays.

Abstract: A polymer or organic light emitting display may be formed on a substrate by patterning the light emitting material using a screen printing technique. In this way, displays may be formed economically, overcoming the difficulties associated with photoprocessing light emitting materials. A binary optic material may be selectively incorporated into sol gel coatings coated over light emitting elements formed from the light emitting material. A tricolor display may be produced using a light emitting material that produces a single color.

Abstract: An organic light emitting device display may be formed of at least two moisture impervious layers sealed to one another using an epoxy material having a desiccant formed within the epoxy material. Any moisture or other solvents that tend to penetrate into the region between the front and back plates of the display where the organic light emitting material resides, will be trapped by the desiccant within the filler material.

Abstract: A tiled display may be formed by temporarily securing a plurality of modules to a substrate. Thereafter, the tiled array may be tested to insure that each module is functional. If each module is functional, the modules may be permanently secured to the substrate. If any modules are defective, they may be replaced and the tiled array may be retested.

Abstract: An organic light emitting diode (OLED) display includes an array of OLED pixels that generate heat and an array of thermally conductive elements positioned between the OLED pixels and a thermally conductive back panel. In one embodiment of the invention, the thermally conductive elements may be solder joints deposited over cathode contacts and anode contacts at each OLED pixel. The solder joints provide a path of low thermal resistance from the OLED pixels to the back panel. Also, the solder joints may serve as an array of electrical connections from back panel interconnects to the cathode lines and anode lines.

Abstract: A backframe may be utilized to align a plurality of emissive display tiles precisely with respect to one another. The individual display tiles may be removable from the backframe for replacement or other reasons. As a result, the spacing between individual tiles in an overall large format display may be precisely controlled in some cases. In addition, regularly occurring gaps between adjacent tiles may be filled with a suitable light absorbing material to reduce the visibility of seams.

Abstract: According to one aspect of the present invention, an apparatus is provided in which a first display element and a second display element are arranged adjacent to each other forming a seam therebetween. Each display element includes a front panel that has a black matrix and a plurality of pixel elements disposed on a first surface thereof. The black matrix is patterned to cover at least a portion of the first surface along an edge of the first surface proximate the seam. The plurality of pixel elements are disposed in those regions of the first surface that are not covered by the black matrix. Each display element, in one embodiment, further includes a back panel attached to the first surface of a corresponding front panel. The first and second display elements are attached to a cover plate using an index-matching adhesive in which the corresponding adhesive is used to fill the seams between the first and second display elements to a predetermined thickness.

Abstract: Tiled flat-panel displays have increased mechanical stability due to the addition of stiffening straps affixed across seams between individual display modules. The stiffening straps may increase mechanical strength of the display by redistributing stress placed on the display from the front of the display to the straps.

Abstract: The lifetime of an organic light emitting device display may be increased by initially driving the display at a substantially constant luminance. For example, over an initial period of the display's lifetime, the display may be driven at a level that may be below its maximum possible light output. After a given amount of time at a substantially constant output luminance, the luminance may be gradually decreased over a second portion of the lifetime of the display.

Abstract: A light directing apparatus comprising an LED array having RGB light emitting diode structures arrayed longitudinally along a substrate to form a plurality of RGB triplet groups and a lenslet array having a plurality of lenslet structures positioned adjacent a respective one of the RGB triplet groups. The lenslet structures include for each respective RGB triplet group a plurality of cylindrical lenses indexed to its respective RGB triplet group. The cylindrical lenses are longitudinally arrayed in parallel to said RGB light emitting diode structures. This arrangement results in greater optical efficiency because light from the LEDs is preferentially directed in a desired direction where an observer is most likely to be.
