Abstract:
1. A light emitting driving apparatus for a display device, the apparatus comprising: a plurality of light emitting driving blocks, wherein the plurality of light emitting driving blocks respectively include: a first node applied with a second light emitting power source voltage according to a clock signal input to a first clock signal input terminal and applied with a first light emitting power source voltage according to a clock signal input to a second clock signal input terminal, a second node applied with the first light emitting power source voltage according to the clock signal input to the first clock signal input terminal, the second node being coupled to a relay signal output terminal outputting a relay signal, a third node applied with the first light emitting power source voltage according to the clock signal input to the first clock signal input terminal, and applied with a third light emitting power source voltage according to a clock signal input to the second clock signal input terminal, the third node being coupled to a reverse light emitting signal output terminal outputting a reverse light emitting signal, a first transistor turned on by a voltage of the first node to transmit the second light emitting power source voltage to a light emitting signal output terminal outputting a light emitting signal, and a second transistor turned on by a voltage of the second node to transmit the first light emitting power source voltage to the light emitting signal output terminal.
