DRIVING METHOD OF DOT-MATRIX DISPLAY PANEL, DRIVE CIRCUIT FOR DOT-MATRIX DISPALY PANEL, DOT-MATRIX DISPLAY DEVICE AND INFORMATION PROCESSING SYSTEM PROVIDED WITH DOT-MATRIX DISPLAY DEVICE
DRIVING METHOD OF DOT-MATRIX DISPLAY PANEL, DRIVE CIRCUIT FOR DOT-MATRIX DISPALY PANEL, DOT-MATRIX DISPLAY DEVICE AND INFORMATION PROCESSING SYSTEM PROVIDED WITH DOT-MATRIX DISPLAY DEVICE
To expand display data for a low-resolution dot matrix display apparatus to display data for a high-resolution dot matrix display apparatus without causing the reduction of the speed of processing and without requiring clocks of different frequencies, a driver circuit comprises intermediate value generating circuits for generating intermediate values of a plurality of adjacent display data according to the expansion ratio in a driver circuit of a dot matrix display apparatus and by applying also the outputs of the intermediate value generating circuits to a dot matrix display panel, the display data is expanded inside of said driver.
