Light Emitting Scanning Drive Unit, Array Substrate and Method for Outputting Light Emitting Scanning Signal

A light emitting scanning drive unit, wherein the light emitting scanning drive unit is configured to output a light emitting scanning signal, and comprises:

• a pull-up control unit, configured to receive a first clock signal, and transmit a high-level reference voltage to a pull-up node according to the first clock signal in one scanning cycle so as to control the pull-up node to be in a high-level state;
• a pull-up output unit, electrically connected to the pull-up node, and transmitting, when the pull-up node is in the high-level state, the high-level reference voltage received to a light emitting scanning terminal and outputting the high-level reference voltage as the light emitting scanning signal;
• a pull-down control unit, electrically connecting a pull-down node and the pull-up node, and configured to control the pull-up node to be in a low-level state and to control the pull-down node to be in a high-level state in each time period of two non-overlapping time periods in one scanning cycle;
• and
• a pull-down output unit, electrically connected to the pull-down node and the light emitting scanning terminal, and configured to, when the pull-down node is in the high-level state, output a low-level reference voltage received to the light emitting scanning terminal and output the low-level reference voltage as the light emitting scanning signal.
