摘要： The present invention is intended to achieve an improvement in the horizontal resolution of an active matrix semiconductor display device. In accordance with the present invention, by supplying a modulated clock signal obtained by frequency modulating a reference clock signal at a constant period to a driving circuit of an active matrix semiconductor display device or to a driving circuit of a passive matrix semiconductor display device, signal information (the presence or absence of an edge, the extent of nearness) relative to the vicinity of the sampling of video signals (image signals) sampled on the basis of this modulated clock signal can be written to the corresponding pixels of the semiconductor display device as shading information. The driving method of the present invention makes use of a phenomenon which apparently makes the resolution of an image display higher owing to the shading information (visual Mach phenomenon and Craik-O'Brien phenomenon).

摘要： A device for displaying a stereoscopic image in which cross-talk is suppressed. A left eye image and a right eye image alternately displayed on a liquid crystal display panel are viewed through an eye shutter having a left eye and a right eye shutter which are alternately switched. The image is displayed on the panel by sequentially supplying scanning voltages on a scanning electrode array and supplying image data voltages on a data electrode array in synchronism with the scanning voltages. The display panel is divided into an upper part and a lower part which are scanned separately in opposite directions. The left eye image is displayed in the first field during which all scanning electrodes in both parts are scanned, and the right eye image is similarly displayed in the second field following the first field. A certain time interval is provided between the first and second fields, while properly setting the eye shutter switching timing. Thus, cross-talk images are displayed only in limited regions close to upper and lower edges of the display panel. The display panel may be scanned in a single scanning method, and the displayed image may be held with a lower brightness to suppress the cross-talk images.

摘要： A method realizes gradations on a display employing an antiferroelectric liquid crystal material. The method involves at least two scan periods to drive the display. The waveforms of voltages applied to the display in the two scan periods are symmetrical to each other with respect to 0 V. Each of the scan periods consists of a selected period and an unselected period. The waveform of a voltage applied in the selected period is modulated to control the response time of the antiferroelectric liquid crystal material and adjust the light transmittance thereof in the following unselected period.

摘要： An antiferroelectric liquid crystal display apparatus free from burn-in and achieving high display quality is provided by providing means for preventing pixel brightness from varying between pixels continuously held in an ON (bright) state and pixels continuously held in an OFF (dark) state. Aging processing is performed to saturate the brightness level of pixels into a stable state and thereby prevent the occurrence of a white brightening phenomenon. For this purpose, the brightness at a no voltage condition (base brightness) is set to a normalized level for all pixels in the liquid crystal panel that are required to exhibit uniform display performance. Further, temperature variations in the liquid crystal panel are eliminated to stabilize the brightness level and thereby prevent the occurrence of a white darkening phenomenon. Means is also provided for repeatedly performing normalization processes automatically or manually.

摘要： In a liquid crystal display using a liquid crystal exhibiting a smectic phase, a display of good quality is accomplished by alleviating the burn-in phenomenon caused by its layer structure or by an internal electric field induced by spontaneous polarization. To achieve this, the liquid crystal display is equipped with a display data conversion circuit which forcibly sets an arbitrary pixel into a prescribed display state for a prescribed period regardless of the display data to be written to the pixel, thereby correcting the change of its layer structure and preventing the internal electric field due to the spontaneous polarization occurring in the same direction from lasting for too long a period.

摘要： A method simultaneously drives a plurality of lines of a display employing an antiferroelectric liquid crystal material. The polarity of the start of a waveform applied to a first one of the simultaneously selected lines is opposite to the polarity of the starts of waveforms applied to the other simultaneously selected lines. Each select period is divided into n sections. A data waveform applied to any one of data electrodes (column electrodes) of the display in synchronization with the select waveforms is determined according to column vectors of a unit matrix of n rows by n columns. The sign of a first one of the n column vectors is inverted. A maximum among voltages applied to pixels of the display must be sufficiently larger than the threshold of the ferroelectric liquid crystal material. The absolute value of the threshold is set between the sum of and the difference between the absolute values of the select and data waveforms.

摘要： The present invention relates to an antiferroelectric liquid crystal display device, by which a time (namely, a ferroelectric saturation time tr) required for transition of the state of a liquid crystal, which has been in a dark state, to a saturated bright state is reduced. A method of establishing a precedent driving period in such a manner as to be precedent to a selective driving period and of obtaining a value, at which the ferroelectric saturation time tr is minimized, of a synthetic voltage from a scanning signal and a display signal in the precedent driving period. A device using the value obtained by this method. In the precedent driving period, a voltage, whose voltage value is .vertline.Vx.vertline., is applied to the liquid crystal. In a selective driving period, a voltage, which is different in polarity from the voltage value .vertline.Vx.vertline. and has a voltage value is .vertline.Vz.vertline., is applied thereto. In other periods, a voltage having a voltage value of 0 is applied thereto. A value of the voltage .vertline.Vx.vertline., at which the ferroelectric saturation time tr is minimized when changing the value of the voltage .vertline.Vx.vertline. while maintaining the voltage .vertline.Vz.vertline. at a constant value, is set as an optimum precedent driving voltage .vertline.VM.vertline..
