  • Patent number: 6747621
    Abstract: The invention relates to a liquid crystal display device, comprising a memory that delays a current display data supplied to a liquid crystal panel by one display period, and a reference table memory that holds a reference data containing multiple reference values determined by the current display data and a delayed display data. Here, the reference table memory has a compensation signal data written in advance, which substantially completes an optical response of the liquid crystal panel within the one display period. The liquid crystal display device supplies the inputted display data after having been converted always into a compensated signal level data to the liquid crystal panel, thus achieving a high-speed response that is completed within the one display period.

  • Patent number: 6707439
    Abstract: In the conventional method of achieving a fast response of a liquid crystal panel, even if the frame rate or the ambient temperature varies, if the image data are the same, the correction value will always be constant; accordingly, the conventional method is impossible of a correction in accordance with the environmental conditions in use. The liquid crystal display of the invention is provided with a plurality of look-up tables, each of which outputs a correction data for correcting an image data to increase the response speed of transmittance of the liquid crystal panel by using the two inputs of the input image data and the image data one frame before that an image memory storing the input image data outputs.

  • Publication number: 20030117364
    Abstract: A liquid crystal display device for color display comprising a transmission type liquid crystal panel capable of controlling an amount of transmission light and a backlight disposed behind the liquid crystal panel capable of emitting three colors of light separately in a time-dividing manner, in which three data corresponding to the three colors of the backlight are displayed sequentially to thereby make the backlight emit a corresponding color in a period corresponding to data to be displayed. The switching can be performed manually or in response to outside signal, between a sequence in which the backlight emits three colors separately one time in one display period to perform color display, and a sequence in which the backlight emits three colors simultaneously three times to perform black-and-white display. The backlight emission can be switched depending on the intensity of outer light, thereby allowing switching between color display with low intensity and black-and-white display with high intensity.

  • Publication number: 20020057249
    Abstract: In a liquid crystal display device of the invention, a reference voltage having a maximum value higher than a maximum value of a signal voltage used for obtaining a predetermined liquid crystal application voltage-luminance characteristic and a minimum value lower than a minimum value of the signal voltage is formed, and a liquid crystal driving circuit forms a correction voltage to speed up a response of a liquid crystal element from this reference voltage, so that the speed of the response of the liquid crystal element is made high even at the time of change from a gray level to white or black.

  • Publication number: 20020050965
    Abstract: The present invention is directed to provide a driving circuit and driving method for a LCD having high performance of moving image displaying within few amount of memory and downscaled circuit. In the present invention, a voltage applied to a pixel to drive liquid crystal material in the pixel is determined as a voltage with which the transparency of the pixel at the end of the current field becomes the designated transparency. To determine the voltage, a data table for quick response in which output data is stored in correspondence with some of the possible value of a preceding field image data and some of the possible value of the current field image data is employed, and the output data corresponding to the preceding field image data and the current field image data is determined by the data table through linear interpolation. The voltage corresponding to the output data is applied to the pixel.

  • Publication number: 20020030652
    Abstract: A liquid crystal display device is provided with a image data inputting means for inputting image data and a image data memory for storing image data comprising a number of bits which is fewer than the number of bits in the image data input to the image data inputting means, on the basis of this image data. In addition, a liquid crystal display device is provided with corrected data generating means for generating corrected data by correcting the current image data input to the image data inputting means, on the basis of previous image data stored in the image data memory. Consequently, the liquid crystal display device enables the capacity of image data memory for storing previous image data to be reduced, thereby yielding a merit in that cost savings can be achieved.

  • Patent number: 6118509
    Abstract: A liquid crystal display device comprising a liquid crystal panel, in which there are formed on opposing faces of a pair of substrates a light shield film or a wiring which do not transmit light, a seal member is applied onto the opposing faces for forming an injection port for liquid crystal, and the pair of substrates are adhered together. A sealing material for sealing the injection port is resin that is curable by ultraviolet light or by visible radiation. At least one of the substrates is formed with a transmitting portion through which the ultraviolet light or visible radiation can transmit at a portion in the proximity of the injection port of the light shield film or wiring. Even if sealing material has penetrated between a pair of substrates, it can be cured by irradiated ultraviolet light or visible radiation by the provision of a transmitting portion, and dispersion of uncured sealing material into liquid crystal can be prevented.
