  • Publication number: 20040151911
    Abstract: An apparatus for depositing and aligning an amorphous film in a single step, a method of forming an aligned film on a substrate in a single step by combining the deposition and alignment of an alignment layer into a single-step using ion beam processing and an amorphous film having an aligned atomic structure prepared by a method in which an aligned film is deposited and aligned in a single step are provided. The film is deposited and aligned in a single step by bombarding a substrate with an ion beam at a designated incident angle to simultaneously (a) deposit the film onto the substrate and (b) arrange an atomic structure of the film in at least one predetermined aligned direction.

  • Patent number: 6724449
    Abstract: A liquid crystal display device includes a first substrate, a dry alignment film deposited over the substrate, a second substrate coupled to the first substrate with the dry alignment film deposited over the second substrate therebetween and forming a cell gap, and a liquid crystal material formed in the cell gap. The dry alignment film allows for a truly vertical alignment of molecules of the liquid crystal material such that the molecules form an angle of substantially 90° relative to the substrate. The dry alignment film can be an oxide layer, a nitride layer, an oxynitride layer or a silicon layer. This dry alignment layer can be treated to form a tilted homeotropic alignment, such that the liquid crystal molecules have a pretilt angle of 0.5 to 10 degrees from a substrate normal direction.

  • Patent number: 6690383
    Abstract: The present invention provides methods and apparatus for the color calibration of displays. These methods are particularly useful for displays having properties different than those associated with cathode ray tubes (CRT). Some displays, for example liquid crystal displays (LCD), have a high luminance black, the chromas of their primaries are not independent of their luminance levels, the intensities of their primaries are not strictly monotonically increasing with respect to their RGB levels, the color additivity of their subpixels is affected by crosstalk or leakage and their color measurements are dependent on the view angle of the observer. Therefore, the usage of CRT methods is deficient for such displays.

  • Publication number: 20040017347
    Abstract: An electrically selectable diffraction grating made of electrodes that can fabricate color pixels of light from a full spectrum of light or a white light with the particular color being based on the spacing sequence of the energized electrodes. In an unaltered state the electrodes are transparent to light, once energized the electrodes become opaque to light. A full spectrum of light can be diffracted into individual wavelengths of colored light when passed through the transparent spaces provided by the unenergized electrodes.

  • Patent number: 6593586
    Abstract: A method is disclosed for forming an alignment layer for use in a liquid crystal cell layer for use in a liquid crystal cell using an ion beam source that includes the steps of: (1) providing a substrate having a surface; (2) providing an ion beam source that emanates an ion beam; (3) providing a mask layer disposed between the substrate surface and the ion beam source. The mask layer has at least two openings disposed between the ion beam source and the substrate surface. The shape and position of the openings reduce the irregularity of the beam exposure in a border region on the surface of the substrate resulting from the ion beam source. The present invention may be used in conjunction with substrate treatment using multiple sweeps with a single ion beam source, or with a substrate treatment using a single sweep with multiple ion beam sources. Also disclosed is an apparatus for practicing the disclosed method.

  • Patent number: 6583847
    Abstract: It is important to accurately align a pair of substrates, such as liquid crystal display (LCD) panels before they are affixed together. This is accomplished, according to the invention, by depositing a number of magnetic field generating elements on one substrate and a plurality of magnetic field-detecting elements on the other substrate. For example, the field-generating elements can be permanent magnets, while the field-detecting can be correspondingly located elements of a magnetic material. Alternatively, both the field-generating and field-detecting elements may be made from permanently magnetic materials.

  • Patent number: 6509947
    Abstract: A device and method for maintaining the volume of a liquid contained within a cavity between two substrates to something equal or nearly equal to that of the volume of the cavity. A particular application is a liquid crystal display (LCD), in which a liquid crystal (LC) material is contained within a cavity between two flat display substrates. The device serves to minimize the volume differential between the liquid and the cavity caused by a change in temperature of the display, such that the formation of bubbles within the liquid is substantially or completely prevented. In so doing, the device essentially eliminates thermally-induced defects that would otherwise be visible to the user.

  • Patent number: 6211851
    Abstract: The elimination of crosstalk between data lines and pixel cells in a thin film transistor/liquid crystal display is accomplished by applying a precharge voltage level for a given data signal level which also provides an equivalent to a compensation voltage for a prior scan line to a given data line for a time period less than the standard scan line period of the display, and applying the data signal to the given data line for the remainder of the scan line period.
