<p>PURPOSE:To make the change of a common signal output terminal position easy and to enable coping with display devices of plural kinds by changing a terminal position of the common signal for displaying a fixed pattern. CONSTITUTION:When a terminal (a) of a selected terminal group 403 is set to '1' and terminals (b), (c) to '0', each input terminal (a) of each multiplexer MPX 1-17 of a multiplexer group 402 is selected and the other terminals (b), (c) are made open or high impedance, in a control IC for driving display. Further, When the terminal (b) of the selected terminal group 403 is set to '1' and terminals (a), (c) to '0', each terminal (b) of the MPX 1-17 is selected, also when the terminal (c) of the selected terminal group 403 is set to '1' and the other terminals (a), (b) to '0', each input terminal (c) of the MPX 1-17 is selected. Thus, positions of common signal output terminals for displaying a fixed pattern are switched between arrays, to the end of terminals (the uppermost) and the other end of terminals (the maximum) by controlling for switching of the selected terminals 403.</p> |
