PIXEL CIRCUIT AND DISPLAY DEVICE INCLUDING THIS PIXEL CIRCUIT

Abstract

This invention relates to a picture circuit and a display device comprising such a picture circuit. The picture circuit comprises an actuator consisting of a first electrode connected to the first node, a first gate electrode connected to the second node, a second electrode connected to the third node, and a second gate electrode to which a pre-set voltage is applied; an actuator consisting of an anode connected to the fourth node and a cathode to which a low-voltage supply voltage is applied; a first switch connected between the first and second nodes; a second switch connected between the third and fourth nodes; a first capacitor connected to the first gate electrode of the actuator; and a second capacitor connected to the third node.
