Patent ID: 7973761

Claim:
A method of driving an information display panel of a passive matrix driving type, in which display media are sealed in a space between two substrates, at least one substrate being transparent, and, in which an electrostatic field, which is generated from an electrode at scan side and an electrode at data side arranged respectively to the opposed substrates in an intersected manner, is applied to the display media so as to display information such as an image, comprising a construction such that at least two or more voltage values or an open state (including a connection state under a high-impedance state) are applied to at least one electrode, wherein an applying voltage of the selected electrode at scan side is VS 1 , at least one electrode among the non-selected electrodes at scan side is open (including a connection state under a high-impedance state), and an applying voltage of the selected electrode at data side is VD 1 , wherein whether a voltage applied to the non-selected electrode at data side is VD 2 or an open state (including a connection state under a high-impedance state) is decided according to the number of the selected electrodes at data side, to which a voltage VD 1 is applied, wherein at least one electrode among the non-selected electrode at data side is open (including a connection state under a high-impedance state); and an applying voltage of the other non-selected electrode at data side is VD 2 , and wherein VD 1 is not equal to VD 2 .
