  • Patent number: 8147906
    Abstract: The present invention relates to a polarizer and a method for produce for producing the same, and an LCD device. The polarizer includes a glass substrate and a metal wire grating disposed on the glass substrate. The polarizer disposed on the LCD device can greatly lower cost of the polarizer and the LCD device. Besides, the polarizer does not absorb incident lights so as to greatly reduce energy loss of lights passing through the polarizer and improve the utilization rate of light energy.

  • Patent number: 8144283
    Abstract: The present invention relates to a circuit and a method for repairing a broken line of a flat panel display device. The circuit includes a second repairing line and a resistance access port is disposed on the second repairing line. The method includes: disposing a resistance access port on a second repairing line of the flat panel display device; and connecting a resistance meeting a display requirement to the resistance access port. The above solutions enable the circuit for repairing to adjust the load resistance so as to adjust the display effect by disposing the resistance access port; thereby improving the repairing effect and making the display quality of the repaired flat panel display device meet the requirement.

  • Patent number: 6563985
    Abstract: An optical filter that is tunable over a wide portion of the spectrum, such as the infrared portion. The filter has a core of silica fiber with a first cladding layer of silica fiber disposed thereon. A long period grating is disposed on the core. A second electro-optical cladding layer is disposed on the first cladding layer. The first cladding layer is ultra thin so as to support only a single resonant band over the spectral portion. The resonant band is tunable to different wavelengths in the spectral portion by a voltage applied to the second electro-optic layer. The electro-optic layer is a copolymer that has a refractive index less than that of the silica fiber material. The optical filter has fast tuning speed (nanosecond range), wide tuning range (>50 nm), low insertion loss (<0.1 dB), narrow bandwidth (<0.5 nm), and low sidelobe (<30 dB).
