Claim 0:
1. A display apparatus, comprising:
a plurality of sub-pixels, wherein the sub-pixels are used for light-emitting display;
a plurality of signal lines, wherein the plurality of signal lines are electrically connected to the sub-pixels and provide a signal required for light-emitting display to the sub-pixels;
a signal line repair module, wherein the signal line repair module is electrically connected to the plurality of signal lines, and configured to repair a disconnected signal line; and the signal line repair module comprises:
at least one repair line;
at least one connection switch group, wherein the at least one connection switch group is disposed in a one-to-one correspondence with the at least one repair line; the connection switch group comprises a plurality of connection switches, the plurality of connection switches in a same connection switch group are disposed in a one-to-one correspondence with the plurality of signal lines, input ends of the connection switches are electrically connected to corresponding signal lines in the plurality of signal lines, and output ends thereof are each electrically connected to a corresponding repair line in the at least one repair line; and
a first shift unit group, wherein the first shift unit group comprises a plurality of stages of first shift units, and the plurality of connection switches in each connection switch group are disposed in a one-to-one correspondence with the plurality of stages of first shift units; each first shift unit comprises a shift output end, and the shift output end of the first shift unit is electrically connected to a control end of a corresponding connection switch; and
a drive chip, wherein the drive chip is electrically connected to the plurality of signal lines and the signal line repair module, and is configured to provide the signal required for controlling the light-emitting display of the sub-pixels to the signal lines, and send, when determining that a disconnected signal line exists, a control signal to the signal line repair module, to enable the disconnected signal line to be electrically connected to the at least one repair line in the signal line repair module; and sending the control signal to the signal line repair module, to enable the disconnected signal line to be electrically connected to the at least one repair line in the signal line repair module comprises: sending the control signal to the signal line repair module, so that the shift output end of the first shift unit corresponding to the disconnected signal line outputs an enable signal, so as to control a corresponding connection switch in a connection switch group to be turned on, to enable the disconnected signal line to be electrically connected to the at least one repair line.
