Apparatus for monitoring and controlling formation of organic layers by physical vapor deposition of organic materials in making organic light-emitting devices is disclosed.

Controlling the thickness of an organic layer in an organic light-emiting device

A direct write lithographic printing plate includes a base layer; a metal light absorbing layer provided over the base layer; and a melanophobic layer provided over the metal absorbing layer and selected to have a thickness which minimizes reflection of light from the metal layer so that light which passes through a selected portion of the melanophobic layer and into the metal light absorbing layer, is absorbed by such metal layer to provide a heat source which causes the removal, at the selected portion, of the melanophobic layer.

Antireflection direct write lithographic printing plates

A process of forming an image comprising imagewise-exposing, by means of a laser, a thermal recording element comprising a transparent support having thereon at least two metal layers having a melting point below about 2,000&deg; C. and a substantially transparent, polymeric spacer layer separating each metal layer from another metal layer, thereby causing portions of each metal layer to coalesce in response to the imagewise exposure by the laser, thus forming the image.

A thermal physical vapor deposition electroluminescent source includes a housing defining an enclosure having side walls and a bottom wall, the enclosure receiving solid organic electroluminescent material which can be vaporized, and the width of the housing having a dimension w,; and the housing has a conductive portion defining a vapor efflux aperture slit having a width w,for permitting vaporized electroluminescent materials to pass through the slit onto a surface of a substrate. A conductive baffle member has width b, the baffle member being centered on the slit and spaced from the side walls and spaced from the top plate by a distance m, the baffle member substantially providing a line-of-sight covering of the slit preventing direct access of vaporized electroluminescent materials to the slit, and preventing particulate electroluminescent materials from passing through the slit; and a straight-line projection from an edge of the slit to an edge of the baffle member onto a side wall defining a position on the side wall such that such position is spaced from the top plate by a dimension L. The ratio of the dimensions w,to w,is in a range of from 1.5 to 6.0; the ratio of L to w,is in a range of from 2 to 6; and the ratio of m to L is in a range of from 0.15 to 0.40. Heat is applied to different parts of the housing to cause vapor deposition.

A method of making a color filter array on a first substrate is disclosed. The method includes depositing and patterning a photoresist layer on the substrate to form openings over selected regions of the substrate; providing a colorant layer having a heat transferable colorant material on a second substrate and positioning the second substrate such that the heat transferable colorant layer is in transferable relationship with but spaced a distance from the first substrate; heating the second substrate sufficiently to cause substantially all of the heat transferable colorant material to transfer across the spaced distance to the patterned photoresist layer on the first substrate; and removing the patterned photoresist layer leaving behind the heat transferable colorant material in the position of the openings over the selected regions of the first substrate.

Imaging elements, such as photographic, electrostatographic and thermal imaging elements, are comprised of a support, an image-forming layer, a transparent magnetic layer comprising magnetic particles dispersed in a film-forming binder and a transparent electrically-conductive layer comprising a sputter-deposited layer of a metal oxide. Use of a sputter-deposited metal oxide provides a controlled degree of electrical conductivity and beneficial chemical, physical and optical properties which adapt the electrically-conductive layer for such purposes as providing protection against static or serving as an electrode which takes part in an image-forming process.

There is disclosed a flexible optical recording element comprising a flexible support having thereon, in order, an SbInSn phase-change alloy optical recording layer and an overcoat layer, the overcoat layer being a silicon oxide layer having an index of refraction greater than about 1.8 at about 800 nm wavelength and a thickness of about .lambda./4, where .lambda. is the wavelength at which the element is read. The element of the invention provides for an advantageous optical tape with a well adhered abrasion resistant overcoat which also provides for excellent corrosion resistance.

A method is disclosed for producing Ag/Ni composite ion selective electrode on polymer substrates. By utilizing a nitrogen glow discharge pretreatment of the polymer substrate, silver may be deposited directly thereon. Further, because of the glow discharge pretreatment, aging of the silver layer prior to nickel deposition and bleaching operation is not necessary.

The heat absorbing layer may include a metal or an alloy either in single or multiple layers having a thickness sufficient to yield a heat capacity of less than 0.2 calories per degree Centigrade per square meter and an optical density at the laser wavelength of 1.0 or greater.

Donor element for laser color transfer

In the manufacture of a decorative sheet material to be bonded to a substrate to provide a surface having a brushed metal appearance, a light-reflective, glossy metal layer is formed on a thermoformable carrier film. A pattern of straight and parallel microscopic cracks is created in the metal layer at a temperature below Tg of the carrier film by bi-directionally bending and drawing the resulting sheet material around a straight cracking member. Thereafter, the sheet material is stretched at a temperature above Tg of the carrier film. This creates an attractive brushed metal appearance of reduced gloss.
