  • Publication number: 20060065020
    Abstract: A molding core includes: a substrate having a roughened article-shaping surface; and a hard coating formed on the roughened article-shaping surface of the substrate and including a protective film that comprises a metal complex of carbon and at least one noble metal selected from the group consisting of Pt, Ir, Ru, Re, Rh, Ta, and Os. The protective film has a thickness greater than 5 ?m so as to increase the number of times that the protective film can be repaired. Combination of the noble metal and carbon can prevent the noble metal of the protective film from reacting with carbon of a diamond tool during turning process.

  • Patent number: 6984546
    Abstract: A method is to form a thin film light emitting device. The method includes providing a transparent substrate. A transparent anode layer, a light emitting layer, a metal cathode layer are sequentially formed on the transparent substrate. A sealant layer is formed to at least cover the light emitting layer and the metal cathode layer. A covering layer having a covering surface is provided. An evaporation process is performed to form an active absorption layer on the covering surface of the covering layer. The covering surface of the covering layer covers on a portion of the sealant layer above the metal cathode layer. The covering layer can have a recess region that is to be formed the active absorption layer thereon. Alternatively, the active absorption layer can be evaporated before the sealant is formed. Moreover, the active absorption layer can be replaced with an insulating layer.

  • Publication number: 20050006652
    Abstract: A light emitting device having an anti-reflective member. The light emitting device includes an anti-reflective member including a reflective layer and a first electrode; a second electrode; and a light emitting layer disposed between the first electrode and the second electrode. The first electrode of the present invention has both electrode and anti-reflective functions. Ambient light is reflected by the first electrode to obtain a first reflected light and reflected by the reflective layer to obtain a second reflected light. The first reflected light and the second reflected light have phase difference; thus, the reflection of ambient light is reduced.

  • Publication number: 20040201346
    Abstract: An organic light-emitting display having an anti-reflective and inert cathode is provided. The cathode is made of a diamond-like carbon material to reduce ambient light reflection and increase contrast. The diamond-like carbon material is an opaque and inert material, so the cathode is anti-reflective and inert.

  • Patent number: 6612888
    Abstract: A packaging method of electro-luminescence devices. By controlling the moisture and oxygen in an environment, a glass substrate with electro-luminescence devices and a glass covering plate corresponding thereto are provided. A frame glues with an opening is applied on each frame on the glass plate that corresponds to each electro-luminescence device on the substrate. The glass plate is laminated with the glass substrate via the frame glues. The glass substrate is cut into individual package including an electro-luminescence device enclosed by a part of the glass substrate, a part of the glass plate and the frame glue except that a side thereof is exposed to the environment via the opening. Each of the packages is disposed in a vacuum cavity with the opening facing the packaging material in a glue tub in the vacuum cavity. The pressure of the vacuum is raised up to a certain value to have the packaging material filling the cavity containing the electro-luminescence in the package.

  • Patent number: 6037190
    Abstract: A method for fabricating a full-color organic electro-luminescent device starts with forming an indium tin oxide (ITO) layer on a glass substrate, and then forming a blue-light emitting layer on the ITO layer. By irradiating predetermined portions of the blue-light emitting layer with certain light sources, pixels that emit different light colors are formed on the irradiated portions of the blue-light emitting layer. An electrode layer is then formed on the corresponding pixels, wherein the electrode layer is further covered by a protection layer. During the operation of the full-color OEL device of the invention, a driving voltage is applied on the ITO layer, the anode, and the electrode layer, the cathode.
