Abstract
Disclosed is a display apparatus comprising a display area and a dummy area; the display area comprises multiple pixel driving circuits and multiple display light-emitting devices, and the display light-emitting devices at least comprise a display anode and a display cathode; the dummy region comprises a cathode voltage line, at least one dummy anode connection line and multiple dummy light-emitting devices, the dummy light-emitting devices at least comprise a dummy anode and a dummy cathode; the display cathode and the dummy cathode are both connected to the cathode voltage line, the display anode being connected to a pixel driving circuit, and the dummy anode is connected to a dummy anode connection line, the dummy anode connection line being configured to cause the voltage differential between the dummy anode and the dummy cathode to be less than the turn-on voltage of the dummy light-emitting device.
