  • Patent number: 7379046
    Abstract: A display driver includes an instruction signal generation circuit which generates a data-fetch-start-instruction-signal; a data latch which fetches display data at data fetch timings including a fetch start timing that is determined by the data-fetch-start-instruction-signal; and a data line drive circuit which drives the data lines, based on the display data fetched into the data latch. The instruction signal generation circuit includes a fetch-start-timing-setting-register into which is set data for determining the fetch start timing of the display data, and the instruction signal generation circuit generates the data-fetch-start-instruction-signal that changes when a period corresponding to the data set in the fetch-start-timing-setting-register has elapsed, with reference to a reference timing.

  • Patent number: 7365734
    Abstract: The present invention addresses the above described problems by simplifying the assumptions on possible motions made by a user. This simplification process can take place by making an assumption that the motion of the device will travel along a certain preferential motion arc, which will be referred to herein as the “Javal arc.” Calculations of motions of the device can be made based on these Javal arcs. Additionally, the double integration of each accelerometer is now eliminated and the expensive accelerometers are replaced by two magnetic sensors.

  • Patent number: 7250928
    Abstract: A light emitting device capable of preventing a luminance of individual light emitting elements from being fluctuated by applying electrical characteristics of TFTs for properly controlling current being fed to individual light emitting elements, and also capable of generating the constant luminance without adversely being affected by possible degradation of organic light emitting layers and variable temperature by way of preventing the luminance of light emitting elements from being lowered through degradation of organic light emitting layers. Instead of controlling the luminance of light emitting elements by means of a voltage applied to TFTs, by way of properly controlling current flowing into TFTs via a signal-line driving circuit, it is possible to hold on the current flowing into light emitting elements at a desired value without adversely being affected by electrical characteristics of TFTs.

  • Patent number: 7248242
    Abstract: The present invention relates to a driving circuit of a liquid crystal display and a driving method thereof. The method includes receiving a M-bit image data from an image data input terminal and extracting N most significant bits (MSB)of the M-bit image data to form a N-bit image data. The N-bit image data is delayed by one frame period to form a N-bit delayed image data. The N-bit delayed image data is compared with P MSB of a current M-bit image data to determine whether to generate a first data voltage according to a first image value selected from a reference table, or to generate a second data voltage according to the current M-bit image data.
