  • Patent number: 6940500
    Abstract: A potential of a data signal line S during a scanning period is charged to a substantially intermediate potential of a data signal at a corresponding frame. Thus, extremely large dispersion does not occur in a potential of each pixel capacitor with respect to a potential of the data signal line S, so that it is possible to restrict dispersion of a leak current flowing via an active element of each pixel. Thus, potential variation of a pixel PIX is reduced, so that it is possible to improve display quality during a non-scanning period. That is, in an active-matrix-type liquid crystal display, when a frame frequency is reduced by setting the non-scanning period to be sufficiently larger than a scanning period while a standby image is being displayed so as to realize low power consumption, the display quality is improved.

  • Patent number: 6937224
    Abstract: A source driver outputs a data signal and a reset (black) signal alternately to a source line. Four-hundred and eighty gate lines are divided into three groups each comprising 160 lines, and connected to gate drivers. A display control section outputs a discriminant signal, a scan start signal and a clock signal to the gate drivers, where the nth gate line is selected with the data signal outputted by the source driver, and where the (n+160)th gate line is selected with the reset signal outputted. Further, n is shifted sequentially. By writing the reset signal during the latter ? of one frame like this, light leakage of pixels that are changed over from white display to black display is eliminated. Also, blurs of edge portions of a motion picture are reduced. Thus, display grade for motion pictures is enhanced with a minimum improvement.

  • Patent number: 6935748
    Abstract: An apparatus and method for recording an image on the surface of a 3D object uses a laser projector that scans a light beam over the surface in an image pattern. The projector operates in a template imaging mode and an image recording mode where the beam scans at a speed that in a single pass/scan mode is typically four to five orders of magnitude slower than in the template imaging mode. A layer of a photosensitive material is applied to the surface of the object either partially or fully. Projection in the template imaging mode can guide the applying. The layer is substantially insensitive to ambient light for at least a period of time necessary to perform a desired processing step on the object. The layer has a maximum spectral sensitivity in the vicinity of the wavelength of the laser light beam. In one or multiple passes of the beam over the image pattern operating in the image record mode, the accumulated light energy dose density is sufficient to react the material and record the image.

  • Patent number: 6937381
    Abstract: An optical pickup device which includes (A) a light source, and (B) an objective lens and an aberration correcting optical system which are located in a light path from the light source to an optical recording medium is so arranged that the aberration correcting optical system imparts a phase distribution to luminous flux which transmits the aberration correcting optical system, so as to correct a predetermined aberration; and an amount of phase of the aberration correcting optical system when correcting the aberration is set in such a manner that the aberration correcting optical system imparts a larger amount of phase at a position farther from a point where the aberration correcting optical system crosses an optical axis of light emitted from the light source. With this, it is possible to increase a tolerance for the center misalignment of the objective lens so as to reduce aberration caused by the center misalignment.

  • Patent number: 6933175
    Abstract: A method is proposed for fabricating a TFBGA (Thin & Fine Ball-Grid Array) package with embedded heat spreader. Conventionally, since an individual TFBGA package is quite small in size, it would be highly difficult to incorporate an embedded heat spreader therein. As a solution to this problem, the proposed method utilizes a single substrate predefined with a plurality of package sites, and further utilizes a heat-spreader frame including an integrally-formed matrix of heat spreaders each corresponding to one of the package sites on the substrate. A batch of semiconductor chips are then mounted on the respective package sites on the substrate. During the encapsulation process, a single continuous encapsulation body is formed to encapsulate the entire heat-spreader frame and all the semi-conductor chips. After ball implantation, a singulation process is performed to cut apart the encapsulation body into individual package units, each serving as the intended TFBGA package.
