1. A display apparatus comprising:
a display panel comprising:
light-emitting elements; and
pixel circuits; wherein at least one of the pixel circuits comprises a pulse width modulation module configured to control light emission duration of the light-emitting element; and
sweep signal lines configured to provide a sweep signal to the pulse width modulation module;
wherein the sweep signal lines comprise first sweep signal lines extending in a first direction, and at least two of the first sweep signal lines are connected through a first connection line extending in a second direction that intersects the first direction;
wherein the sweep signal lines further comprise second sweep signal lines extending in the first direction, and at least two of the second sweep signal lines are connected through a second connection line, the second connection line extends in the second direction;
wherein the sweep signal comprises a first sweep sub-signal and a second sweep sub-signal;
wherein the first sweep signal lines receive the first sweep sub-signal at a moment K1, and the second sweep signal lines receive the second sweep sub-signal at a moment K2; and
wherein K1≠K2;
wherein the display panel comprises first display regions and second display regions alternately arranged in the second direction;
wherein the first sweep signal lines are located in the first display regions, and the second sweep signal lines are located in the second display regions; and
wherein, in the first direction, at least one second connection line is disposed between adjacent two of the first connection lines; and/or
wherein, in the second direction, at least one second connection line is disposed between adjacent two of the first connection lines.
