  • Publication number: 20110159610
    Abstract: Metal induced polycrystallized silicon is used as the anode in a light emitting device, such as an OLED or AMOLED. The polycrystallized silicon is sufficiently non-absorptive, transparent and made sufficiently conductive for this purpose. A thin film transistor can be formed onto the polycrystallized silicon anode, with the silicon anode acting as the drain of the thin film transistor, thereby simplifying production.

  • Publication number: 20100289755
    Abstract: Disclosed are systems, methods and techniques to integrate touch-sensing functionality with a liquid crystal display (LCD) panel. In a particular implementation, light sensing detectors are disposed on a backlight panel to detect changes in light incident on the backlight panel in response to a physical touching on a surface of an LCD panel. A location of the physical touching may then be estimated based upon signals received from the light sensing detectors.

    Abstract: There is disclosed a structure for a stacked organic light emitting device in which a plurality of emissive units are disposed between the anode and the cathode. The emissive units comprise at least a hole-transport layer and an electron-transport layer. An intermediate layer is disposed between two adjacent emissive units and the intermediate layer comprises at least two sub-layers, a first sub-layer being formed of a material that can inject electrons into one emissive unit and a second sub-layer being formed of a material that can inject holes into the adjacent emissive unit. The sub-layers are formed of metals or inorganic materials only and a surface of the intermediate layer may be treated by a low pressure CF4-plasma.
