Claim 13:
14. The crack detection method for a display panel according to claim 13, wherein the determining crack state information of the display panel according to the light emitting state of the sub-pixel of the display panel comprises:
there being a crack between the first terminal and the third node of the first crack detection line when a sub-pixel connected with the first data line is in a second light emitting state and a sub-pixel connected with the second data line is in the second light emitting state;
there being no crack between the first terminal and the third node of the first crack detection line, a crack between the third node and the second terminal of the first crack detection line, and no crack between the first terminal and the second terminal of the second crack detection line when the sub-pixel connected with the first data line is in the second light emitting state and the sub-pixel connected with the second data line is in the first light emitting state; and
there being a crack between the first terminal and the second terminal of the second crack detection line and no crack between the first terminal and the second terminal of the first crack detection line when the sub-pixel connected with the first data line is in the first light emitting state and the sub-pixel connected with the second data line is in the second light emitting state;
wherein one of the first light emitting state and the second light emitting state is an on state, and the other of the first light emitting state and the second light emitting state is an off state.
