Abstract: In a multiplex driving method of a matrix type liquid crystal electro-optical device comprising a liquid crystal layer provided between a first substrate carrying row electrodes (X 1 , X 2 ,...) and a second substrate carrying column electrodes (Y 1 , Y 2 ,...) wherein said row and column electrodes define a matrix of pixels, said row electrodes are divided into groups and, during a selection period, the row electrodes of one group are simultaneously selected by applying a respective row voltage waveform to each of them while applying a non-selection voltage to the row electrodes of all other groups. The groups are sequentially selected. The row voltage waveforms are composed of a plurality of successive row select pulses defining a corresponding plurality of successive row select patterns. To each column electrode is applied a respective column voltage determined in response to each row select pattern and display data. The selection period is divided into plural subperiods (t 1 , t 2 , t 3 ) and and, when a frame is defined as the time period equal to said selection period times the number of row electrode groups and a picture period comprises a certain number of frames, said column voltages are modulated during said picture period in accordance with gradation information of grey scale display data,.

Abstract: A display driving method, wherein only one voltage of an unselected scanning line is used, and when the displaying of an image by display elements is not carried out, the voltage level of data lines corresponding to the display elements is the voltage level of the unselected scanning line. The power consumption of the display can be reduced. The smallest possible area out of the whole screen is used for the displaying of an image, and the other area is put in a display-off state (display-off mode) by using this driving method. For example, the reduction of the consumption of the display in a standby mode is effected. The image display area and the area in a display-off state can be set freely, respectively. When the multiline driving method and the above-described driving method are combined, the power consumption can further be reduced.

Abstract: This invention relates to an image display method, which includes the steps mainly characterized by allowing the observer to stereoscopically view the three-dimensional partial image by guiding a light beam coming from the three-dimensional partial image to a predetermined position via a partial parallax barrier, which is formed by light directivity controlling means, arranged to oppose the image displaying means, by alternately arranging stripe-shaped light-transmitting portions and light-shielding portions on an area corresponding to the three-dimensional partial image; and controlling, using light amount adjusting means, the brightness levels of the partial images to be observed by the observer in correspondence with the view point numbers of the partial images.

Abstract: A passive liquid crystal display is enhanced by selectively applying low frequency signals to the columns of electrodes on the substrates sandwiching a liquid crystal, selectively applying high frequency signals to the rows of the electrodes so the first and second signals activate the liquid crystal at selected ones of said rows and columns, and passive storing the energy in capacitances exhibited by said rows at the high frequency with an inductor. The low frequency may be 10 to 20kHz and the high frequency 1 MHz or higher.

Abstract: A second group of drive voltages V3 to V5 has a voltage range that is separate from, and does not overlap a first group of drive voltages V0 to V2. The first group of drive voltages V0 to V2 is supplied from first power sources VDD and VSS through operational amplifiers OP1 and OP2. The second group of drive voltages V3 to V5 is set with reference to VEE, and is supplied from the first power sources VDD and VSS through the operational amplifiers OP1 and OP2. Voltage conversion capacitors C11 and C12 are charged by turning on and off a first group of switches SW11 to SW13, and are discharged by turning on and off a second group of switches SW14 to SW16, thus causing the output of the second group of drive voltages V3 to V5 which have references to VEE.
