    摘要: CPU writes display character codes corresponding to a liquid crystal display position to display RAM to cause any desired character to be read from character generator ROM and to be displayed. There are provided a scroll display line designation register for designating a desired display line to be scrolled and a scroll dot quantity register for designating the scroll quantity in pixels. A scroll register supplies, to a segment shift register, character data which is delayed by the designated number of dots with respect to the character data on the designated display line and causes the display line to be displayed.

    摘要: In a display control drive device that displays an image on a display device, a data transfer rate may vary depending on received image data because of a difference in an image size. Assuming that driving force with which a driver or an amplifier is driven is designed based on a maximum data transfer rate and the driver or amplifier is operated with the driving force, when the transfer rate is low, an unnecessary current is consumed. According to the present invention, a display control drive device sequentially reads display data from a display memory in which the display data is stored, produces three primary color image signals that are applied to pixel locations in a dot-matrix color display device, and transmits the signals through a common external output terminal in a time-sharing manner. Moreover, the display control drive device produces control signals to be applied to selection switching elements that are incorporated in the display device and that selectively apply an input image signal to any of three source lines. The display control drive device includes: a unit that determines one horizontal period on the basis of a clock received from outside synchronously with display data; and a signal production circuit that produces and transmits the control signals, which are applied to the selection switching elements, so that the control signals will have a pulse duration equivalent to a time calculated by trisecting one horizontal period.

    摘要: A display control device and technique for controlling displays on a display unit, in which a plurality of display segments are two-dimensionally arranged (e.g. a dot matrix type display unit), is provided. The technique is effectively applicable to a write data latch circuit of a memory for storing display data in the display control device, such as, for example, a liquid crystal display control device, a mobile electronic apparatus, etc. A display drive control technique for controlling a moving picture display mode of a display device is also provided. The display drive control circuit controls a picture display mode of a display device for displaying still pictures and moving pictures to a liquid crystal display device, such as, for example, a dot matrix type display devices, an organic EL display device, etc.
