Abstract
A display device includes a first transistor controlled by a first control signal and connected between an image data signal line and a first node, a third transistor controlled by a second control signal and connected between the first node and a second node, a second transistor connected to the second node and connected between a power line and a third node, a fourth transistor controlled using a third control signal and connected between a reference voltage power line and the second node, a fifth transistor controlled by a fourth control signal and connected between an initialization voltage power line and the third node, and a sixth transistor controlled by a fifth control signal and connected between a pre-charge voltage power line and the first node.
Claims8
A display device comprising:
- an image data signal line supplied with a data voltage;
- a power line supplied with a constant voltage;
- a reference voltage power line supplied with a reference voltage;
- an initialization voltage power line supplied with an initialization voltage;
