摘要： An edge detecting circuit detects whether a particular pixel belongs to an edge by determining whether the differential value of the pixel from the neighboring pixel is equal to or greater than a threshold. Based on the detection result, an emphasis converter stops OS drive when the image of a pixel area is regarded as an edge image in accordance with the detected result of the edge detecting circuit and implements OS drive when the image of a pixel area is not regarded as an edge image. In this way, the edge detecting circuit detects edge portions of the input video, whereby OS drive in the emphasis converter can be controlled so as to be turned on and off.

摘要： An emphasis converter 52 compares the image data of the current vertical period with the image data of the previous vertical period and controls the input image data to a liquid crystal display panel 4 based on the emphasis conversion parameters stored in tables of ROMs 3a to 3c so as to achieve accelerated drive. A microcomputer 38 is able to realize stable control of selecting emphasis conversion parameters by adding hysteresis to the detected temperature from a thermistor 37 even when the detected temperature fluctuates up and down crossing the temperature threshold.

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 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： 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.
