ABSTRACT:
To expand display data for a low-resolution matrix display apparatus to display data for a high-resolution matrix display apparatus without causing a reduction in the speed of processing and without requiring clocks of different frequencies. This is accomplished by providing intermediate value generating circuits for generating intermediate values of a plurality of adjacent display data according to an expansion ratio in a driver circuit of a matrix display apparatus and by also applying the outputs of the intermediate value generating circuits to the matrix display panel. Thus, the display data is expanded by the driver.
