    Abstract: An image forming apparatus comprises an exposure light source, an image bearing member and a printer head interposed therebetween. The printer head has a micro-shutter array which comprises a plurality of micro-shutters arranged in a matrix comprising a plurality of rows and a plurality of columns. Each micro-shutter comprises a first electrode connected to a terminal of a thin film transistor, a second electrode forming a common electrode and a liquid crystal interposed therebetween. On the first electrode is further provided an opposing conductor film through an insulating film, whereby a charge storage capacitor is formed. Because of the charge storage capacitor, an effective voltage applied across the liquid crystal is kept at a high level, whereby an optical signal with good contrast is given to the image bearing member even when the printer head is driven according to a high degree of time-division scheme.

    Abstract: A display apparatus, such as a liquid crystal display apparatus, includes a display panel having scanning lines and data lines arranged in a matrix form, and drive means for applying scanning signals and data signals to the scanning lines and data lines, respectively, so as to display a picture on the display panel. The drive means includes a plurality of data line drivers disposed so as to apply data signals to the data lines, and picture data transfer control means for transferring picture data for one scanning line drive period to the plurality of data line drivers. The picture data transfer control means further includes means for supplying a signal for setting a period for intermission of picture data transfer during a period for transferring the picture data for one scanning line drive period to the plurality of data lines. As a result, the processing load on the picture data transfer control means can be reduced, and a cascade connection between data line drivers leading to a mal-operation due to noise can be alleviated.

    Abstract: A data transfer method for transferring data to an information-side driver for driving a display apparatus is provided. Wherein, driver circuits each comprising a chip address/video data discrimination circuit and a unit driver are mounted around said display apparatus. A unique chip address is set for each of the unit drivers by means of a hardware pattern. Data exchange with the driver circuits is performed so that chip address information and video data information are time-divisionally transferred to the target unit driver using a chip address/video data common bus line and a chip address/video data discrimination control signal.
