  • Patent number: 8110971
    Abstract: A light emitting element of the present invention includes an electrode substrate; a thin-film electrode; and an electron acceleration layer sandwiched between the electrode substrate and the thin-film electrode. In the electron acceleration layer, as a result of a voltage applied between the electrode substrate and the thin-film electrode, electrons are accelerated so as to be turned into hot electrons. The hot electrons excite surfaces of the silicon fine particles contained in the electron acceleration layer so that the surfaces of the silicon fine particles emit light. Such a light emitting element of the present invention is a novel light emitting element, which has not been achieved by the conventional techniques. That is, the light emitting element of the present invention is able to (i) be produced by using a silicon material, which is available at low price, through a simple production method, and (ii) efficiently emit light.

  • Patent number: 8063551
    Abstract: In the fabrication of a display, such as an OLED display, the OLED layer stack is deposited on an electrode on the substrate. The electrode may be the anode and may comprise indium tin oxide (ITO). Desirably, the deposited films are of uniform thickness over the entire active area of the electrode. If the films are not uniform, then areas that are thicker will not emit light, and areas that are too thin may emit light in a less than optimum efficient way (power loss) and/or result in leakage current leaks through the device in a way that does not generate photons. An active-matrix organic light emitting diode comprises a substrate with a larger well size or wider channel width compared to the emission area. This improves the effective aperture ratio, which improves pixel intensity homogeneity.
