1. A display module, comprising: a display panel, a light control panel, at least one first circuit board for the display panel, and at least one second circuit board for the light control panel,
wherein the display panel and the light control panel are stacked,
the display panel is on a light-emitting side of the light control panel,
a light-emitting surface of the display panel is on a first surface, and
at least part of an orthographic projection of any one of the at least one first circuit board on the first surface does not overlap with an orthographic projection of the at least one second circuit board on the first surface in a direction perpendicular to the first surface;
the display panel comprises a plurality of first connection lines and a plurality of first signal lines, each of the plurality of first connection lines comprises a first wire portion, a second wire portion, and a third wire portion which are sequentially connected; the light control panel comprises a plurality of second connection lines and a plurality of second signal lines, each of the plurality of second connection lines comprises a fourth wire portion, a fifth wire portion, and a sixth wire portion which are sequentially connected;
the display panel further comprises a first common electrode in a peripheral region of the display module;
the light control panel further comprises a second common electrode in the peripheral region of the display module;
the display module comprises a first side and a second side opposite to each other in the first direction;
two outermost first connection lines among the plurality of first connection lines comprise a first connection line on the first side and a first connection line on the second side;
two outermost second connection lines among the plurality of second connection lines comprise a second connection line on the first side and a second connection line on the second side;
a distance between a second wire portion of the first connection line on the first side and an edge of the first common electrode close to the first connection line on the first side is a first distance;
a distance between a second wire portion of the first connection line on the second side and an edge of the first common electrode close to the first connection line on the second side is a second distance;
a distance between a fifth wire portion of the second connection line on the first side and an edge of the second common electrode close to the second connection line on the first side is a third distance; and
a distance between a fifth wire portion of the second connection line on the second side and an edge of the second common electrode close to the second connection line on the second side is a fourth distance;
a product of a difference between the first distance and the second distance and a difference between the third distance and the fourth distance is a positive value.
