摘要： In a liquid crystal display device for receiving television signals by an interlace scanning method, number of the rows of pixels and of scan signal lines on a liquid crystal panel is increased to be the same as the number of valid scan lines of 1 frame of television signals. The original video signals to be inputted to the device are compressed to 1/2, and interpolating signals are added to every line of the compressed signals to form pseudo video signals. Shift register operation of a scan driver and the segment driver are done twice as fast as that in the conventional device, and start timing of the shift register operation of the segment driver is controlled to be shifted by 1/2 horizontal scanning period between the even field and odd field, while the pseudo video signals are applied to the segment driver. Consequently, to the rows of pixels to which original video signals are applied in the even field and to the rows of pixels to which interpolating signals are applied in the even field, interpolating signals and original video signals are applied in the odd field, respectively. Consequently, display can be carried out seemingly in accordance with the interlace scanning method.

摘要： A liquid crystal displaying panel is formed of a number of pixels in the horizontal and vertical directions based on a PAL system of many horizontal scanning lines. A polarity reversing circuit reverses the polarity of an input video signal at a predetermined period and a signal feeding circuit samples the video signal reversed in the polarity and holds it. The signal feeding circuit feeds the output to the respective data lines of the liquid crystal panel and can feed the output corresponding to the data lines of an NTSC video displaying region by a switch to the data lines corresponding to the blank part other than the NTSC system video displaying region. A scanning circuit feeds a driving signal to the respective gate lines of the liquid crystal displaying panel and can feed the output corresponding to the gate lines of the NTSC video displaying region by a switch so that, when the NTSC system is selected, an intrinsic NTSC video will be displayed in the displaying region and the NTSC video will be displayed also in the blank part. That is to say, by alternately driving the liquid crystal of all the pixels, a video of the same picture quality can be displayed in the PAL system and NTSC system without deteriorating the liquid crystal.

摘要： A display device, such as thin film EL display device, is formed by interposing a dielectric layer between a plurality of scanning electrodes and a plurality of data electrodes which are arranged at right angles. Modulation voltage is varied in accordance to the display data, and is applied to the data electrodes. Further, a writing voltage is applied to the scanning electrodes in sequential line order, to thereby perform gradation display. Further, the writing voltage includes a ramp voltage, which varies with time. Thus, the peak of the current flowing through the luminescent layer of the picture element, as a current contributing to the luminescence, is suppressed to a low level. contributing to the luminescence, is suppressed to a low level. Accordingly, the energization period of the current is also elongated. Thus gradation display over multiple levels is made possible and a stable display of different gradation levels is enabled.

摘要： This invention relates to gradation display by a pulse width control method (PWM method) in every pixel in a capacitive display apparatus such as a liquid crystal display apparatus. The driving voltage applied to the electrodes is varied slowly, and the number of gradations of gradation display by the PWM method is increased. Since the capacitive display apparatus is used, for each electrode further from the drive circuit, the driving pulse is more influenced and its persisting duration is extended. As a result, even in identical gradation data, uneven colors may occur. The pulse width applied to the electrodes is gradually decreased as scanning of the electrodes sequentially occurs. Therefore, the brightness of the capacitive display apparatus may be made uniform over the entire screen surface.

摘要： A memory circuit for use with a spatial light modulator having an array of electrically addressable, micro-mechanical, modulating elements, whose address electrodes determine how that element will affect incident light. The memory circuit has at least one static memory cell in communication with the address electrodes of each modulating element. Each memory cell receives data for determining its micro-mechanical movement via a bit-line down each column of memory cells. A row select signal determines whether the data will be written to that row. A two-level voltage line supplies power to each memory cell, with one level being used for writing to the cell and another level being used for operating the modulating element.

摘要： The display apparatus has a band-pass filter for limiting an input video signal to a bandwidth equal to or narrower than half of a frequency band which is calculated from the number of display elements along the horizontal direction of a screen. Further a computing circuit computes vertical interpolation video data in order to correct for the difference between the number of display elements along the vertical direction and the number of scanning lines along the vertical direction of the input video signal. Even if various kinds of video signals are input, the display apparatus displays images corresponding to the video signals, by controlling the brightness of display elements arranged in a matrix form.
