  • Patent number: 7292213
    Abstract: A method and device for repairing defective pixels of a liquid crystal display panel. First, examine the liquid crystal panel to obtain the locations of defective pixels on a liquid crystal display. Next, input a pixel signal wherein the pixel signal further comprises a pixel brightness signal used to control a pixel with a first brightness according to the pixel signal. When the pixel signal is used to be inputted to the defective pixel, the pixel brightness signal of the pixel signal will be replaced by a default brightness signal wherein the default brightness signal controls the pixel with a second brightness. Of which, the second brightness, whose level of brightness is of complete darkness for instance, is dimmer than the first brightness. At last, output pixel signals.

  • Patent number: 7190333
    Abstract: The present invention relates to a coding method intended to improve the performance of GCC coding based on the temporal centre of gravity of displayed video codes. According to the invention, the number of video levels that can be selected in order to implement the GCC coding is increased by increasing the number of subfields in the video level display frame. This increase in the number of subfields is made possible by simultaneously addressing the cells of at least two adjacent rows of the PDP during at least two subfields of the video image display frame.

  • Patent number: 7187373
    Abstract: Amplifier circuits (AMPi, AMPj) are provided corresponding to data lines (DLi, DLj) arranged corresponding to columns of display pixels (PX). In the amplifier circuit, a non-inversion input of a differential amplifier circuit (32) is connected to the corresponding data line, and an inversion input node (N2) is connected to a capacitance element (34). Before pixel data of a displaying pixel element is read onto the data line, the non-inversion input of the differential amplifier circuit is precharged to a predetermined voltage level, and an output node of the differential amplifier circuit is coupled to the inversion input node (N2). The differential amplifier circuit operates as a voltage follower, and the capacitance element stores a comparison reference voltage including information corresponding to an offset of the differential amplifier circuit.

  • Patent number: 7176852
    Abstract: A front substrate contains a plurality of scan electrodes and sustain electrodes. Two strips of scan electrodes and two strips of sustain electrodes are alternately disposed on the substrate. In addition, a plurality of auxiliary scan electrodes is disposed on the front substrate so as to be parallel to the scan electrodes. On the back substrate, a plurality of priming electrodes is disposed parallel to the scan electrodes. Each auxiliary scan electrode has electrical connections to the scan electrode that performs scanning earlier than the scan electrode adjacent to each auxiliary scan electrode. With the structure above, a priming discharge occurs between the auxiliary scan electrodes and the priming electrodes.

  • Patent number: 7167165
    Abstract: A user is provided with guidelines that are temporarily displayed with content, in order to assist the user in neatly and accurately writing electronic ink. The guidelines may appear when the user moves a writing tool, such as a stylus or pen, close to a display and writing surface. Alternately, the guidelines may appear after the user has begun to write electronic ink, so that the guidelines can correspond to the angle at which the user is writing, the size of the user's handwriting, or both. As the user writes the electronic ink onto the writing surface, the handwritten electronic ink is added to the content being rendered on the display. After the user has finished writing electronic ink and moves the writing tool away from the writing surface, the guidelines are deleted, and are not added to the displayed content. In this way, the user can employ the temporary guidelines to accurately and legibly write electronic ink into content, without the guidelines themselves becoming a permanent part of the content.

  • Patent number: 7161582
    Abstract: A data input device for use with a tracking surface having light-scattering properties. The device comprises a coherent light source for projecting a coherent light beam onto the tracking surface to reflect a speckle pattern. A detector having a field of view detects and images the speckle pattern. The detector operates in a tracking mode when the field of view intersects the coherent light beam. The intersection of the coherent light beam and the field of view comprise a detection zone. Relative movement between the coherent light beam and the tracking surface within the detection zone between is detected in the tracking mode, based on the reflected speckle pattern. Relative movement between the coherent light beam and the tracking surface outside the detection zone is not detected. A controller responsive to the detector operates in the tracking mode for correlating the imaged laser speckle pattern to track the relative movement within the detection zone.

  • Patent number: 7145582
    Abstract: A method of driving a plasma display device that includes a plurality of scanning electrodes, a plurality of sustaining electrodes, and a plurality of data electrodes is such that, when m is any given integer, the data electrodes are applied with a negative polarity pulse when a voltage applied to the scanning electrodes gradually decreases during the initialization period, if a final pulse in a sustain period of an (m?1)-th subfield is applied to the scanning electrodes and an m-th subfield includes an initialization period. If the final pulse in the sustain period of the (m?1)-th subfield is applied to the sustaining electrodes and the m-th subfield includes the initialization period, the data electrodes are applied with a positive polarity pulse when a voltage applied to the scanning electrodes gradually increases during the initialization period.

  • Patent number: 7034815
    Abstract: A method, system and apparatus for synchronizing an analog video signal to an LCD monitor is described. For each of a succession of associated video frames are surveyed for a number of displayed features based upon a pseudo-random selection of regions into which the displayed video frame is divided. During successive associated video frames, a minimum number of features each is which is generated by an associated pixel clock is determined based upon a pre-selected number of scans. Subsequent to the determination of the minimum number of features, a transition region for each of plurality of horizontal resolution values is determined by scanning through a selected number of pixel clock phases. Based upon a minimum transition zone corresponding to a maximum change in the number of features for a particular pixel clock phase, an associated horizontal resolution is provided.
