    摘要: Output voltages of R-2R ladder resistor type digital-to-analog conversion circuits are once stored in sample and hold capacitors through sample and hold charging amplifiers and the voltages stored in the capacitors are then supplied to a liquid crystal panel through panel drive amplifiers and multiplexers simultaneously. Power supplies to the digital-to-analog conversion circuits and the charging amplifiers are turned on by means of switches only during the period that the voltages are written in the capacitors and turned off during other periods. Two systems of the capacitors and the panel drive amplifiers are provided in order to make the operation of charging the analog voltages to the capacitors and the operation of taking out the analog voltages stored in the capacitors to supply the voltages to the liquid crystal panel in parallel.

    摘要: In RGB time division drives, there is capacitor coupling due to the effects of fluctuation in the drain lines, and thus, the image quality deteriorates (lateral smearing), so that the display brightness becomes different from the desired display brightness due to delay in the convergence of the fluctuation of the common potential, and thus, it is a goal to prevent the image quality from deteriorating (lateral smearing).In RGB time division drives, the order of time division is switched for each frame, or in the direction of the horizontal lines.

    摘要: An image processing unit (2 in FIG. 1) discards a high gray level side of input image data (RiGiBi) in accordance with a chroma coefficient (Csc), thereby to generate a signal of lowered chroma, and it expands the signal into output image data (RoGoBo) of full scale. Besides, the image processing unit (2) generates an image adjustment parameter (Th) and performs a control so as to reduce power of backlight (6), in interlocking with the full-scale expansion.

    摘要: In a hold-type display device, such as a liquid crystal display device, so-called blurring which appears on a profile of a displayed animated image can be suppressed without degrading the brightness of the image. An image based on video data to be inputted to a display device is displayed for every frame period and, thereafter, the image is masked with a blanking image. Here, the ratio between an image display period of the video data and a blanking image display period in one frame period is adjusted, based on the number of pixel rows selected in a pixel array in response to a scanning clock for respective periods, the frequency of the scanning clock, and shortening of a horizontal period of display signal inputting to every pixel row with respect to a horizontal scanning period of the video data, whereby the image can be efficiently cancelled using the blanking image.
