摘要： The specification and drawings relate to liquid crystal matrix display panel which is used to display a television image or the like and disclose the technology in which: the pixels on a matrix are divided into at least two groups of pixels, in particular, two right and left pixel groups: these pixel groups are respectively independently driven within one horizontal scanning interval; thereby widening the width of the vertical scanning signal and allowing the image signal to be sufficiently transferred to the liquid crystal cells; and thereby allowing a high-quality image to be displayed without causing the lack of luminance and a variation in luminance in association with the realization of a large area and a fine pitch of the display panel.

摘要： A specific pattern in an inputted digital signal is detected (13) and the input digital signal is sampled and held (14) in accordance with such a detection output. A clock (15-17) whose phase is synchronized with the input digital signal is generated on the basis of the sampling output. With such a construction as mentioned above, the phase of the clock can be optimally controlled by a simple construction. The clock can be precisely extracted from the input digital signal, so that the operation of a circuit is also stable.

摘要： A device is arranged to detect the level of an input digital signal by detecting a specific pattern from the input digital signal and to control the level of the input digital signal according to a result of the level detection. The arrangement enables the device to accurately detect the amplitude of a reproduced signal obtained at the detecting point of data which has the specific pattern, to keep the level of the reproduced signal unvarying at the data detecting point and to lessen errors of reproduced data.
