    摘要: In one embodiment of the present invention, a large-screen or high-definition LCD is provided with its display quality improved significantly by reducing the viewing angle dependence of γ characteristic. Each pixel includes first and second subpixels, to which different voltages are applicable. The device further includes electrically independent storage capacitor trunks, each being electrically connected to the respective storage capacitor counter electrodes of either the first or second subpixels through storage capacitor lines. One vertical scanning period (V-Total) of an input video signal is divided into at least two subframes, in each of which a display signal voltage is written on each pixel. Two consecutive vertical scanning periods of the input video signal include a sequence in which the display signal voltage is written at the same polarity in two consecutive subframes and then has its polarity inverted in the next subframe. A storage capacitor counter voltage has, in each subframe, a first waveform, oscillating in a first cycle time PA, which is an integral number of times (and at least twice) as long as one horizontal scanning period (H), and a second waveform, defined such that the effective value of the CS voltage storage capacitor counter voltage has a predetermined constant value every predetermined number of consecutive vertical scanning periods of the input video signal. Between two subframes in which the polarity of the CS voltage is inverted, the first waveforms of the CS voltage storage capacitor counter voltages have a phase difference of 180 degrees.

    摘要: The vertical scan period of the input video signal is divided into at least two sub-frames. In each of the sub-frames, a display signal voltage is written into each pixel. Two vertical scan periods in which the input video signals are continuous contain a sequence of two continuous sub-frames where a display signal voltage is written with the same polarity and a sub-frame where the polarity of the display signal voltage is inversed. The auxiliary capacity opposing voltage includes, in each of the sub-frames, a first waveform vibrating with a first cycle of the horizontal scan period multiplied by an integer not smaller than 2 and a second waveform in which an effective value of the auxiliary capacity opposing voltage is set to a predetermined constant value for each vertical scan period of a predetermined number of continuous input video signals.

    摘要: Data signal lines, scanning signal lines, and pixels are formed in each of first and second regions of a liquid crystal panel, and the first half of a current frame and the second half of the current frame are written to the first and second regions, respectively. A data signal with polarity inverted for each vertical scanning period is supplied to each data signal line. A scanning direction of the first region is identical to a scanning direction of the second region and the first and second regions are arranged to line up in this order in the scanning direction. In the first and second regions, the potential of the data signal is corrected according to a distance from a scanning start end portion.

    摘要: A display control circuit of a liquid crystal display device generates a double-speed progressive image signal by changing an input image signal based on interlaced scanning into a progressive scanning mode, and also by doubling the frame frequency. With the double-speed progressive image signal, a pixel value equivalent to an odd-numbered scanning line in an odd-numbered frame remains unchanged, a pixel value equivalent to an even-numbered scanning line is replaced with a black pixel value, a pixel value equivalent to an even-numbered scanning line in an even-numbered frame remains unchanged, and a pixel value equivalent to an odd-numbered scanning line is replaced with a black pixel value. An image that the double-speed interlace image signal represents is displayed on a liquid crystal panel.

    摘要: A liquid crystal display apparatus includes a plurality of areas in which response speeds greatly different from each other coexist in a pixel. A first replacement process section replaces the image data of the desired target frame with a first gradation, when a gradation transition from a current frame to a desired target frame corresponds to the above gradation transition. A second replacement process section replaces the image data of the current frame with a second value. The first value is set to a value causing the pixel to respond at a relatively higher speed without the occurrence of the excessive brightness. Without avoiding the deterioration of the image, it is possible to drive a liquid crystal display apparatus including areas whose response speeds are different from each other coexist in the pixel, such as a liquid crystal display apparatus of vertically aligned mode and normally black mode.

    摘要: The cold cathode tube for illuminating pixels with light which is in accordance with an output signal has luminance which gradually increases at a rise and gradually decreases at a fall per one frame time. The cold cathode tube contains a fluorescent material of only one of three primary colors of light, and has a certain OFF period or dimming period per one frame time. Between a diffusing plate and a reflecting plate are provided partition walls for parting emitting areas, so that the illumination light of one cold cathode tube does not reach the display elements to be illuminated by the other cold cathode tubes. The emission of each display element is changed per one frame time between a normal ON state and a dim state. The cold cathode tube has two or more OFF periods within one frame time, and, luminance of the cold cathode tube is changed per one frame period. As a result, it is possible to suppress shortening of life of emitters in an illuminating section, and to relieve lowering of luminance of the emitters, and also to obtain a desirable display quality even in a fast-moving image.

    摘要: A liquid crystal display of the present invention facilitates grayscale level transition from a previous frame to a current frame, in such a manner that a modulation driving process section reads out, from one look-up table, corrected image data corresponding to a combination of image data of a previous frame and image data of a current frame and then outputs this corrected image data, irrespective of the ambient temperature. Meanwhile, a temperature circuit controls a heater so as to either stop the heating by the heater when a temperature of the liquid crystal panel exceeds a threshold value which is 1° C. through 1.5° C. higher than a target temperature, or start the heating by the heater when the temperature of the liquid crystal panel goes below a threshold value which is 1° C. through 1.5° C. lower than the target temperature, the target temperature being determined in advance to be in a range between 48° C. and 63° C. In this manner, it is possible to realize a liquid crystal display which is simple in circuit arrangement but can improve a response speed while restraining the degradation of display quality to be hardly recognizable for the viewer.
