Abstract:
An emission driver according to example embodiments includes a plurality of stages each having an input block; an output block; a first signal processing block controlling a voltage of a first node; a second signal processing block controlling a voltage of a fourth node in response to the signal supplied to a third input terminal and a voltage of a fifth node; a third signal processing block controlling the voltage of the fourth node; a fourth signal processing block controlling the voltage of the third node; and a stabilization block electrically connected between the input block and the output block to limit a voltage drop between the first node and the third node. The stabilization block may limit a voltage drop between a second node and the fourth node by lowering a voltage of a second power source to the fifth node.
