DISPLAY DEVICE, DRIVE CHIP, AND ELECTRONIC DEVICE

Disclosed are a display apparatus, a drive chip, and an electronic device. A signal line repair module (10) of a display panel (001) includes a plurality of connection switches (12) and a plurality of sequentially-cascaded shift units (11) that are disposed in a one-to-one correspondence, where an input end of each connection switch (12) is electrically connected to one signal line (DL), an output end thereof is electrically connected to another signal line (DL), and a shift output end (OUT) of each shift unit (11) is electrically connected to a control end of a corresponding connection switch (12). When determining that a disconnected signal line (DL) exists, a drive chip (30) sends a control signal to the signal line repair module (10), so that the shift output ends (OUT) of a plurality of shift units (11) sequentially output enable signals, and the shift unit (11) corresponding to a connection switch (12) electrically connected to the disconnected signal line (DL) continuously outputs enable signals, so that the connection switch (12) electrically connected to the disconnected signal line (DL) is continuously turned on. The display apparatus may repair a disconnected signal line without being returned to a factory and a manual operation.
