Classification: CPC G | IPC G

Claim 9:
10. A drive chip, wherein the drive chip is configured to:
provide a signal to a plurality of signal lines to control sub-pixels to perform light-emitting display; and
when determining that a disconnected signal line exists, provide a control signal to enable the disconnected signal line to be electrically connected to a repair line in a signal line repair module, wherein providing the control signal to enable the disconnected signal line to be electrically connected to the repair line in the signal line repair module comprises: sending a control signal to the signal line repair module, to control a shift output end of a first shift unit corresponding to the disconnected signal line to output an enable signal, and control a corresponding connection switch in a connection switch group to be turned on, so that the disconnected signal line is electrically connected to the repair line, wherein sending the control signal by the drive chip to the signal line repair module comprises:
sending a selection signal to the selection signal line, so that the connection switch electrically connected to the selection signal line transmitting the selection signal is turned on, and an enable signal output by the first shift unit is transmitted to a control end of a corresponding connection switch, so that the corresponding connection switch is turned on.
