发明名称 DISPLAY DEVICE AND ITS DRIVING METHOD
摘要 <p>A display panel (110) comprises a plurality of optical elements (OEL) each having a pair of electrodes and performing an optical operation according to current passing between the pair of electrodes, a current line (DL), a switch circuit (Tr2) that passes a write current (Ia) with a predetermined current value through the current line (DL) during a selection time (Tse) and stops passing current during a non-selection time (Tnse), and a current storage circuit (Trl, Tr2, Cs, Cp) that stores current data according to the current value of the write current (Ia) passing through the current line (DL) during the selection time (Tse) and that supplies a drive current (Ib) having a current value, which is obtained by subtracting a predetermined offset current (Ioff) from the current value of the stored write current (Ia), to the optical elements (OEL) during the non-selection time (Tnse). The current storage circuit (Trl, Tr2, Cs, Cp) includes a first capacitor device (Cs) to which an electrical charge corresponding to the write current (Ia) is written and a second capacitor device (Cp) to which an electrical charge corresponding to offset current (Ioff) is written, and the second capacitor device (Cp) has a capacitive value, which is equal to or larger than the first capacitor device (Cs).</p>
