DISPLAY DEVICE WITH TOUCH PANEL

摘要

PURPOSE:To provide the display device with the touch panel which adjusts the display position of display data on an LCD on the basis of the phase shift quantity between the LCD and touch panel. CONSTITUTION:The position shift quantity between the LCD 15 and touch panel 17 is converted into the number of dots of the LCD 16, which is stored in a position correction memory 19; when a display instruction or touch data of the touch panel 17 are inputted, a control circuit 18 reads corresponding character data out of a character generator memory 21 and expands the data into dots at a position in a DRAM 22 corresponding to the display position, but the expansion position is corrected at this time according to the position shift quantity in the position correction memory 19. The dot data after the position correction are converted by a data converting circuit 23 into serial data, which are inputted to an LCD driving circuit 24, and the LCD driving circuit 24 displays the character on the LCD 16 at the position after the correction.
