  • Lens module of scanner
    Patent number: 7982962
    Abstract: A lens module of a scanner is provided, including a first lens with a positive diopter, a second lens with a negative diopter, a third lens with a positive diopter, and a fourth lens with a negative diopter. The first, second, third, and fourth lenses are sequentially arranged from an object end to an image end of the lens module, and at least one of the first and fourth lenses is an aspheric lens. The fourth lens has a focal length f4 and an objective side surface with a radius of curvature R7, wherein 0.1<R7/f4<1.
    Type: Grant

  • FABRICATION OF FULL-COLOR OLED PANEL USING MICRO-CAVITY STRUCTURE
    Publication number: 20070286944
    Abstract: Methods of making top-emitting or bottom-emitting full-color OLED flat panel using micro-cavity structure for primary colors are disclosed. The primary colors are realized by setting a different thickness for the hole injection layer of the OLEDs for each primary color, while keeping the thickness of the hole transport layer, the emission layer, the electron transport layer the same for all the OLEDs. Steps for predetermining the respective thickness of the hole injection layer for each primary color are also disclosed.
