Abstract:
An array base plate includes a silicon substrate including multiple cascaded EOA units disposed at a peripheral area; the EOA units are electrically connected to a pixel driving unit; each EOA unit includes an input circuit transmitting a signal input by a light-emitting control signal input line to the EOA unit; a first control circuit transmitting a second power signal input by a second power signal line to a first node, and transmitting a first power signal input by a first power signal line to a second node; a second control circuit transmitting a second clock signal to a third node or transmitting the second power signal to the third node; a pull-up circuit transmitting the first power signal to a light-emitting control signal output line, and a pull-down circuit transmitting the second power signal to the light-emitting control signal output line.
