  • Patent number: 7792006
    Abstract: The present invention provides an optical head with a single or multiple sub-wavelength light beams, which can be used in arenas such as photolithography, optical storage, optical microscopy, to name a few. The present invention includes a transparent substrate, a thin film, and a surface structure with sub-wavelength surface profile. The incident light transmits through the transparent substrate, forms a surface plasma wave along the sub-wavelength aperture located within the thin film, and finally re-emits through spatial coupling with the sub-wavelength profile of the surface structure. As the coupled re-emitting light beam or light beams can maintain the waist less than that of the diffraction limit for a few micrometers out of the surface with sub-wavelength profile in many cases, this invention can have applications ranging from micro or nano manufacturing, metrology, and manipulation by using light beams with waist smaller than the diffraction limit.

  • Patent number: 7646021
    Abstract: A TFT array substrate includes a substrate, a patterned first metallic layer, a patterned stack layer, a patterned dielectric layer, a patterned transparent conductive layer, and a patterned third metallic layer. Elements of each TFT in the TFT array substrate are arranged vertically, so that the TFT array substrate has relatively small fabrication area and is operable with a high conducting current. Further, the storage capacitance can be enhanced by enclosing or sandwiching the second metallic layer with the common lines and the transparent electrodes. In such a way, pixel flashing caused by those coupled signals can be reduced, thus promoting displaying quality thereof.

    Abstract: An optical reflective film that includes pluralities of repeating units is provided. The repeating unit includes a first multiplayer-film unit and a second multiplayer-film unit. The first multiplayer-film unit and the second multiplayer-film unit are by stacking a first polymeric material A and a second polymeric material B.

The stacking order in the first multiplayer-film unit is 1A:xB:1A, and the stacking order in the second multiplayer-film unit is 1B:yA:1B, where x and y represent the optical thickness multiple of the middle polymeric material relative to the neighboring polymeric material. X and y are not equal and have a proportional relationship to each other.
