  • Publication number: 20130280836
    Abstract: A method of selectively applying a material to a surface of a substrate from a stamp with a raised surface using an energy activated release layer is provided. The release layer is applied to at least a first portion of a surface of the stamp. A layer of the material is applied to the raised surface of the stamp. The raised surface of the stamp is placed in contact with the surface of the substrate such that the material layer is situated therebetween. Thereafter, the release layer is activated with energy, causing the material layer to release from the raised surface of the stamp, and to adhere to the surface of the substrate. Alternatively, the entire stamp surface may be coated with the release layer and the release layer may be selectively activated in the areas in which the material on the stamp surface is in contact with the substrate.

  • Patent number: 8564187
    Abstract: A color display device that increases the efficiency of use of white light emitted from an organic light-emitting diode (OLED) in producing an improved color display. The device includes a plurality of color OLED display pixels, which include an OLED, a color filter layer, and a color conversion matrix sandwiched between the OLED and the color filter layer. The color filter layer has a plurality of color filter elements including a red, green and blue color filter element. The array of subpixels comprised in the color conversion matrix is composed of semiconductor nanocrystals uniformly dispersed in an organic binding material, which may be employed in either down-emitting or up-emitting color OLED display devices.

  • Patent number: 7456380
    Abstract: An image sensor includes a plurality of photosensitive sites; a plurality of asymmetrical-shaped microlenses positioned spanning the photosensitive sites; wherein incoming light is directed in a predetermined direction by an asymmetrical surface of the asymmetrical-shaped microlenses onto the photosensitive sites for capturing the light in a substantially uniform manner.

  • Patent number: 5889277
    Abstract: An image sensor and method of making such sensor is described. The sensor includes an integral color filter array, comprising: a semiconductor substrate having an optically planar top surface; a plurality of spaced image pixels formed in the substrate; and an array of physically contiguous color filter elements embedded in the substrate whose top and bottom surfaces are coplanar and which have no overlap of color filter layers between adjacent color filter elements.

  • Patent number: 5756239
    Abstract: For use in forming a high resolution color filter array the following steps are used: coating a colored layer containing a binder, a colorant in the binder, the binder being transparent over the entire visible electromagnetic spectrum and remaining so even after extended treatment with elevated temperature and light; hardening the colored layer; providing and patterning a photoresist layer over the hardened colored layer; and treating the patterned photoresist layer so that it is selectively resistant to oxygen plasma etch. Further processing steps are used to complete the colored filter array.

  • Patent number: 4526856
    Abstract: A novel photoresist formulation is provided which provides low striations and excellent wetting properties. The photoresist composition may be applied by spin casting on various substrates used in integrated circuit manufacture. The essential component in this invention is the solvent composition which consists of cyclopentanone (or cyclopentanone-cyclohexanone blend) in combination with an aliphatic alcohol of 5-12 carbon atoms. These solvent components when used in certain specific ratios provide unexpectedly good wetting of various substrates and low striation films.
