Abstract
There provide an emission electrode scanning circuit, an array substrate and a display apparatus. The emission electrode scanning circuit includes a plurality of sub scanning circuits connected in cascades, each of which includes a shift register unit, a scanning signal generation unit and a driving output unit. Each sub scanning circuit provides a driving signal to the emission electrode respectively, thereby avoiding bringing in a plurality of driving signal lines from outside of the array substrate. And the plurality of sub scanning circuits shares the emission electrode driving signal line and needs an input of only one start signal to drive the emission electrode scanning circuit to send the emission electrode driving signal progressively. The emission electrode scanning circuit is suitable to be integrated in the seal region of the array substrate, without setting the Fan-out having numerous input lines, which is advantageous for implementing the narrow frame of the display apparatus and also avoids crosstalk produced between the input lines and the gate voltage lines.
