    摘要: A liquid crystal display device in which the time necessary for luminance to change from application of a different gray-scale voltage exceeds one frame period in relation to the response as a luminance change time of the liquid crystal. The liquid crystal display device includes a signal control circuit for preventing the content of a preceding frame from being displayed as an after-image and preventing also deterioration of image quality. The signal control circuit includes a frame memory for delaying by one frame the first display data inputted from the external device, an arithmetic operation circuit for comparing the second display data stored in the frame memory and delayed by one frame with the first display data, and an addition/subtraction circuit for adding and subtracting correction data outputted by the arithmetic operation circuit to and from the first display data.

    摘要: A liquid crystal display device of the present invention capable of enlarging and displaying to a high picture quality even when display data having a lower resolution than a liquid crystal panel is inputted, is provided with storage element groups every drain line within latches of a liquid crystal driver. A portion of the storage element groups simultaneously captures display data. In doing so, the same liquid crystal apply voltage is outputted from drain lines corresponding to these storage element groups. Storage element groups corresponding to neighboring drain lines then simultaneously capture display data so as to enlarge an image in the horizontal direction. The rate of enlargement can be regulated by changing the number of storage element groups simultaneously capturing display data. A scanning driver then simultaneously selects a plurality of rows with a select voltage being applied to the simultaneously selected rows of pixel elements in the same period so as to enlarge the image in the vertical direction. Enlarged displaying is therefore possible by the liquid crystal driver regulating an output period of the liquid crystal apply voltage even when rows are selected one at a time.

    摘要: In order to improve the phase skipping characteristic and the transient response characteristic when using a tracking filter to regenerate the carrier from a PSK signal, a pair of output points having different equivalent noise bandwidths are set by using a first filter having a broad equivalent noise bandwidth and a second filter having a narrow bandwidth. The phase difference between the output points is detected by a phase detector, the phase of the signal at the output point having the broader noise equivalent bandwidth being changed by a phase shifter if a phase difference is detected. The filters and associated circuitry can be connected in either parallel or serial configuration, and the frequency division necessary in the tracking filter can be accomplished in more than one stage to simplify the phase shifting requirement. Additionally either channel switching or polarity inversion of the demodulated baseband signal, or both, can be performed on the basis of such phase differences.

    摘要: A band-pass filter circuit comprising a band-pass filter for removing noise modulation components from an input signal comprising a carrier sine wave, a phase detector for detecting a phase difference between input and output signals of the band-pass filter, a loop filter supplied with the output from the phase detector, and automatic control means for effecting control by the output from the loop filter so that a difference between the frequency of the input sine wave and the center frequency of the band-pass filter is reduced to zero. For carrier recovery in a burst mode, the loop filter is selected for each particular case so that high-speed pulling-in is possible even if a narrow-band filter is employed as the band-pass filter for the removal of noise components. Also, high-speed and high-precision pulling-in is achieved when many bursts of different frequencies are applied in one frame period. Further, when common and individual frequency variations occur at the same time, high-speed pulling-in is also achieved for each burst.
