EMITTING DRIVER FOR DISPLAY DEVICE, DISPLAY DEVICE AND DRIVING METHOD THEREOF

摘要

A light emitting driving device for a display device includes a plurality of light emitting driving blocks. Each of the plurality of light emitting driving blocks comprises; a first node in which a second light emitting power voltage is applied according to a clock signal inputted to a first clock signal input terminal, and a first light emitting power voltage is applied according to a clock signal inputted to a second clock signal input terminal; and a second node in which the first light emitting power voltage is applied according to the clock signal inputted to the first clock signal input terminal, and a third light emitting power voltage is applied according to the clock signal inputted to the second clock signal input terminal. The second node is connected to a reverse light emitting signal output terminal in which a reverse light emitting signal is outputted. The each of the plurality of light emitting driving blocks comprises; a first transistor which is turned on by the voltage of the first node and transfers the second light emitting power voltage to a light emitting signal output terminal in which a light emitting signal is outputted; and a second transistor which is turned on by the voltage of the second node and transfers the first light emitting power voltage to the light emitting signal output terminal.
