1. A display device, comprising: a display module and an infrared touch assembly; wherein
a display surface of the display module is in a shape of rectangle with an edge extending in a first direction and an edge extending in a second direction, and the first direction and the second direction are perpendicular to each other;
the infrared touch assembly comprises an infrared emitting frame and an infrared receiving frame which are disposed oppositely and extend in the first direction, a plurality of infrared emitting units are fixed in the infrared emitting frame, and a plurality of infrared receiving units are fixed in the infrared receiving frame;
an orthographic projection of a light-emitting surface of the infrared emitting frame in the display module is located in an area outside a display area of the display module; and
a distribution density of the plurality of infrared emitting units in the infrared emitting frame is uneven;
wherein the infrared emitting frame comprises a first area and a second area, and a distribution density of infrared emitting units in the first area is greater than a distribution density of infrared emitting units in the second area;
wherein the plurality of infrared emitting units have a sequence number from 1 to N, the first area is a middle area of the infrared emitting frame, the infrared emitting units in the first area are arranged at different intervals, and the second area is an area adjacent to the first area in the infrared emitting frame;
a distance between an infrared emitting unit numbered 1 and an infrared emitting unit numbered N is a third distance;
a distance between a center point between two infrared emitting units with a minimum spacing in the first area and the infrared emitting unit numbered 1 is a fourth distance; and
a ratio between the fourth distance and the third distance is a third ratio, and the third ratio is a 0.38 less then 0.62.
