摘要： It is an object of the present invention to provide a multilevel optical recording medium in which influence of variation in characteristics of a recording layer in a plane of the recording layer on reproduced data can be corrected. The multilevel optical recording medium according to the present invention includes at least a recording layer 12 and is constituted so that data can be recorded therein in a multilevel manner by controlling a state of the recording layer 12 among multiple stages and the multilevel optical recording medium according to the present invention is characterized in that a plurality of calibration signals are stored in the recording layer 12. According to the thus constituted multilevel optical recording medium, since an optical data recording and reproducing apparatus can detect and correct for the variation in characteristics of the recording layer 12 in the plane thereof, even in the case where variation in characteristics of the recording layer 12 in the plane thereof is present, data recorded in the multilevel optical recording medium in a multilevel manner can be read in a desired manner.

摘要： A liquid crystal display device includes a plurality of scanning electrodes, a plurality of signal electrodes, and a plurality of picture element electrodes connected to intersections of scanning and signal electrodes via a plurality of switching transistors. A plurality of counter electrodes are arranged opposite to the picture element electrodes. The polarity of display signals applied to the signal electrodes is inverted for a period equal to an integer multiple of a pulse width of a scanning pulse applied to the scanning electrodes. Signals of alternating polarity are applied to the counter electrodes in synchronism with the polarity inversion of the display signals. In this way, non-uniform display contrast along the signal electrode direction of the display screen is avoided by eliminating the stray capacitance timing differences according to the position of picture element electrodes along the signal electrode direction of the display screen.

摘要： A method of driving a matrix-type liquid crystal display panel comprising the step of dividing each scan pulse delivered to a plurality of row electrodes connected to the liquid crystal panel into plural scan periods; supplying video signal data via real-time operation during the initial divided period during alernate scan periods; generating new and proper signal source during the rest of the scan periods; and supplying data from the new signal source so that data can be written into liquid crystal layers. When dividing the width of the scan pulse into n pulses, the frame frequency can be raised n-times, thus making it possible to achieve a satisfactory liquid crystal picture display without the slightest flicker.
