Claim 16:
17. The electronic device according to claim 11, wherein:
the display apparatus further comprises a signal line defect detection circuit, the signal line defect detection circuit is electrically connected to the signal lines and configured to detect a defect of the signal lines, and the signal line defect detection circuit comprises:
a detection line, configured to transmit signals on the signal lines to the drive chip;
a plurality of detection switches, wherein the plurality of detection switches are disposed in a one-to-one correspondence with a plurality of signal lines, an input end of each detection switch is electrically connected to a corresponding signal line, and an output end of each detection switch is electrically connected to the detection line; and when a detection switch of the plurality of detection switches is turned on, a signal on the signal line electrically connected to the input end of the detection switch is transmitted to the detection line electrically connected to the output end of the detection switch;
a reset line, configured to obtain a reset signal from the drive chip and transmit the reset signal to the detection line; and
reset switches, wherein an input end of each reset switch is electrically connected to the repair line, and an output end of each reset switch is electrically connected to the detection line; and
when each reset switch is turned on, a reset signal transmitted on the reset line electrically connected to the input end of the respective reset switch is transmitted to the detection line.
