Abstract:
A color filter having a bi-layer metal grating is formed by nanoimprint lithography. Nanoimprint lithography, a low cost technology, includes two alternatives, i.e., hotembossing nanoimprint lithography and UV-curable nanoimprint lithography. Manufacture steps comprises providing a substrate with a polymer material layer disposed thereon. A plurality of lands and grooves are formed in the polymer material layer, and a first metal layer and a second metal layer are disposed on the surfaces of the lands and grooves, respectively. Finally, a color filter having a bi-layer metal grating is obtained.

A driving method for reducing the color shift suitable for driving a display panel is disclosed. The display panel includes at least one scan line, at least one data line, and at least one pixel unit electrically connected to the scan line and the data line. The driving method includes the following steps. First, turn on the pixel unit by the scan line during a frame period. Transmit a frame signal to the pixel unit by the data line during the frame period as the pixel unit is turned on. Turn on the pixel unit by the scan line between the present frame period and the next frame period. Transmit a revising signal to the pixel unit by the data line between the present frame period and the next frame period as the pixel unit is turned on, so as to reduce the color shift of the pixel unit.
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.

Abstract:
The light-guide module for emitting particular polarized light beams includes a splitter for separating non-polarized light beams, a transformer for converting polarization of light beams, and a non-polarized light source. The non-polarized light source emits light beams. Particular polarized light beams pass the splitter and other light beams are reflected by the splitter. Polarizations of reflected light beams and of light beams emitted by the non-polarized light source are converted by the transformer so as to separate the light beams later. Thus the light-guide module for emitting particular polarized light beams loses relatively little light energy.

A pixel unit comprising a first metal layer and a second metal layer. The first metal layer comprises a gate electrode and a first electrode. The second metal layer comprises a drain electrode, a source electrode, and a second electrode. The drain electrode overlaps the gate electrode in a first overlapping region. The source electrode overlaps the gate electrode in a second overlapping region. The second electrode overlaps the first electrode in a third overlapping region. The size of the first electrode approximates that of the second electrode. The first electrode and the second electrode are staggered.
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 first polymeric material A and the second polymeric material B differ from each other in refractive index by at least about 0.03. 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. For the visible light, the ratio of the first multiplayer-film unit and the second multiplayer-film unit in the effective refractive index is about 1.00.
