Abstract
A display driving apparatus includes a matrix display device for displaying an image. The matrix display device has switching elements and data written elements connected to the switching elements. The switching elements and the data written elements are arranged in rows and columns to form a matrix. A plurality of scan lines are arranged in a predetermined number of rows, with each row of the plurality of scan lines being connected to respective ones of the switching elements arranged along a corresponding row of the matrix. A plurality of data lines are connected to the switching elements for supplying lines of display data to be displayed on successive rows of the scan lines, and a data line driver circuit is connected to the switching elements via the data lines for supplying the switching elements connected to successive rows of the scan lines with the lines of display data. The data line driver circuit includes a shift register for receiving and shifting lines of display data supplied in serial thereto, and a latch circuit. The latch circuit successively receives lines of display data from the shift register, holds a previous line of received display data, and supplies the he…
