Abstract: The present disclosure is directed to a method for coating the edge of glass articles. The shaped edge of a glass article is inserted into the slot of a coating apparatus. The coating apparatus includes a vessel containing a UV curable coating material, an element connected to the vessel having the slot, wherein the slot is shaped to receive an edge of the glass article; and a coating pad having a coating surface shaped to conform to the shaped edge of the glass article, the pad having a network of interconnected openings therethrough, wherein the coating pad extends from the vessel and into the element so that the coating surface forms a bottom surface of the slot. An ultraviolet (UV) curable coating material is supplied to the coating pad and the shaped edge is contacted with the coating pad surface to transfer a selected thickness of the coating material from the coating pad to the shaped edge. The UV curable coating material is then cured on the shaped glass edge.

Abstract: A method for forming a fritted cover sheet for sealing a glass package includes providing a transparent substrate having a sealing surface and a backing surface and forming at least one mask on one of the sealing surface of the substrate or the backing surface of the substrate. A sealing frit may be formed on the sealing surface of the substrate such that the at least one mask is positioned adjacent a perimeter defined by the sealing frit.

Abstract: A glass article having an anti-glare surface. The anti-glare surface has a distinctness-of-reflected image of less than 95, and a haze of less than or equal to 50%. In one embodiment, the glass article further includes a smudge-resistant surface disposed on the anti-glare surface. Methods of making the glass article and anti-glare surface are also described.

Abstract: A spine screw assembly is adapted to be loaded from a bottom of a receiver member. The spine screw assembly includes a bone fastener with a head having a groove that removably accepts a clip. The clip acts to retain the head of the bone fastener in the receiver member.

Abstract: A method for sealing an organic light emitting diode (OLED) device is disclosed wherein the OLED device comprises a color filter. A color filter is deposited on a first glass plate or substrate and a glass-based frit is then deposited in a loop around the color filter, The deposited fit loop is then heated by electromagnetic energy to evaporate organic constituents and to sinter the fit in a pre-sintering step. An OLED device may then be assembled by positioning a second glass plate comprising an organic light emitting material deposited thereon in overlying registration with the first glass plate, with the color filer and the organic light emitting material positioned between the plates. The fit is then heated with a laser to form a hermetic seal between the first and second glass plates.

Abstract: Hermetically-sealed packages for electronic components, e.g., OLEDs, are provided. The packages have a first glass substrate (12), a second glass substrate (16), and a wall (14) that separates the first and second substrates (12,16) and hermetically seals the electronic component (18) between the substrates (12,16). The package has a reduced outer unused area characterized by distances Dfirst (32a) and Dsecond (32b) at least one of which, and, in certain embodiments, both of which are less than 200 microns, e.g., one or both of Dfirst (32a) and Dsecond (32b) is approximately 100 microns. The reduction in unused area can be used to increase viewing area, improve electrical lead design, and/or increase package strength through the use of a wider sintered frit wall (14).
