Claim 9:
10. A drive chip, comprising:
a control circuit, configured to: provide a signal to control sub-pixels to perform light-emitting display; and
an input/output circuit, configured to: send a control signal to a signal line repair circuit, wherein sending the control signal to the signal line repair circuit causes a shift output end of a first shift circuit of the signal line repair circuit corresponding to a disconnected signal line to output an enable signal, to control a corresponding selector switch of the signal line repair circuit to be turned on, and wherein after the enable signal output by the shift output end reaches a corresponding connection control circuit of the signal line repair circuit by using the selector switch that is turned on, the corresponding connection control circuit is controlled to keep outputting a turn-on signal, and the turn-on signal is transmitted to a control end of a corresponding connection switch of the signal line repair circuit to turn on the corresponding connection switch, so that the disconnected signal line is electrically connected to the repair line.
