Claim 10:
11. An electronic device, comprising a display apparatus, the display apparatus comprising:
a plurality of sub-pixels, wherein the sub-pixels are configured to be used for light-emitting display;
a plurality of signal lines, wherein the plurality of signal lines are electrically connected to the plurality of sub-pixels and are configured to provide a signal required for light-emitting display to the plurality of sub-pixels;
a signal line repair circuit, wherein the signal line repair circuit is electrically connected to the plurality of signal lines, and configured to repair a disconnected signal line; and the signal line repair circuit comprises:
a repair line;
a connection switch group, wherein the connection switch group comprises a plurality of connection switches, and the plurality of connection switches are disposed in a one-to-one correspondence with the plurality of signal lines, input ends of the plurality of connection switches are electrically connected to the corresponding signal lines, and output ends of the plurality of connection switches are electrically connected to the repair line;
a connection control circuit group, wherein the connection control circuit group comprises a plurality of connection control circuits, the plurality of connection control circuits are disposed in a one-to-one correspondence with the plurality of connection switches, and an output end of each connection control circuit is connected to a control end of a corresponding connection switch, and when the output end of the respective connection control circuit outputs a turn-on signal to the control end of the corresponding connection switch, the signal line electrically connected to the input end of the corresponding connection switch is electrically connected to the repair line electrically connected to the output end of the corresponding selector switch;
a selector switch group, wherein the selector switch group comprises a plurality of selector switches, the plurality of selector switches are disposed in a one-to-one correspondence with the plurality of connection control circuits, and an output end of each selector switch is electrically connected to a connection control end of a corresponding connection control circuit; and
a first shift circuit group, wherein the first shift circuit group comprises a plurality of stages of first shift circuits, the plurality of stages of first shift circuits are disposed in a one-to-one correspondence with the plurality of selector switches, and a shift output end of each first shift circuit is electrically connected to an input end of a corresponding selector switch; and

a drive chip, wherein the drive chip is electrically connected to the plurality of signal lines and the signal line repair circuit, and is configured for providing the signal required for controlling the light-emitting display of the plurality of sub-pixels to the signal lines, and sending, when determining that a disconnected signal line exists, a control signal to the signal line repair circuit to enable the disconnected signal line to be electrically connected to the repair line in the signal line repair circuit, and wherein:
sending the control signal to the signal line repair circuit, to enable the disconnected signal line to be electrically connected to the repair line in the signal line repair circuit comprises:
sending the control signal to the signal line repair circuit, so that a shift output end of the first shift circuit corresponding to the disconnected signal line outputs an enable signal, to control a corresponding selector switch to be turned on; and
after the enable signal output by the shift output end reaches a corresponding connection control circuit by using the selector switch turned on, controlling the corresponding connection control circuit to keep outputting a turn-on signal, and transmitting the turn-on signal to a control end of a corresponding connection switch to turn on the corresponding connection switch, so that the disconnected signal line is electrically connected to the repair line.
