DISPLAY PANEL DEVICE, DISPLAY DEVICE AND METHOD FOR CONTROLLING SAME |
摘要 |
<p>A display panel device includes: an organic EL element (13); a capacitor (14) including first and second capacitor electrodes; a driving transistor (11) having a gate connected to the first capacitor electrode for allowing a drain current to flow through the organic EL element (13) and a source connected to the second capacitor electrode; a selecting transistor (12) switchably interconnecting a data line (20) and the first capacitor electrode for supplying a signal voltage to the capacitor (14); a switching transistor (16) switchably interconnecting the drain of the driving transistor (11) and a positive power line (24); and a controller. The controller is configured to: turn ON the selecting transistor (12) while the switching transistor (16) is ON to supply the signal voltage to the capacitor and flow a current between the source of the driving transistor (11) and the second capacitor electrode; and, after predetermined time period, turn OFF the switching transistor (16) to cause non-conduction between the positive power line (24) and the drain of the driving transistor (11).</p> |
