    摘要: In a method of driving a liquid crystal panel using one horizontal period (1H) as a reversal period, the liquid crystal panel using a TFT as a switching element for driving the panel in units of divided blocks and comprising the block division TFT's (B-TFT), a matrix circuit for driving each block in time division, and a TFT active matrix panel; each block of the B-TFT's is further divided into two half-blocks and a control signal shifted in phase between adjacent two half-blocks is applied to time-divisionally drive the liquid crystal panel at superposed timings. High intensity lines produced at the intersection of blocks due to the charge sharing effect are eliminated to thereby enable a high quality image to be produced.

    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 a lack of luminance or a variation in luminance in association with the realization of a large area and a fine pitch of the display panel.

    摘要: A matrix-type display panel comprises a display panel having a plurality of scanning lines, a plurality of data lines and a plurality of picture elements disposed at each intersection of the scanning lines and data lines, and analog switching elements for sampling-and-holding information signals which are applied to the data lines in synchronism with scanning signals applied to the scanning lines. The matrix-type display panel is driven by a driving method comprising: applying such switching pulses to the analog switching elements that time-serial pulses among them and shifted in phase from each other and overlap each other in a same duration.

    摘要: A tactile sensation providing apparatus, so as to reduce an influence by provision of a tactile sensation on detection of a position by a touch sensor, includes a touch sensor 11, a tactile sensation providing unit 12 disposed near the sensor 11 and configured to vibrate the sensor 11, a touch sensor control unit 20 configured to transmit a scanning signal to the sensor 11 and, by receiving the signal from the sensor 11, to detect the position of the contact to the sensor, signal lines 16, 18 configured to transmit the signal between the sensor 11 and the control unit 20, and a tactile sensation control unit 30 configured to, based on the position of the contact detected by the control unit 20, control the providing unit 12 to vibrate the sensor 11. The providing unit 12 is disposed avoiding overlapping with the lines 16, 18.
