1. A light-emitting assembly, comprising:
a first substrate having a first surface configured for receiving touches, the first substrate having a light-transmitting area which transmits light;
a light guide layer on a side of the first substrate away from the first surface;
a first reflective layer between the first substrate and the light guide layer, an opening being formed in the first reflective layer, and a boundary of a projection of the opening on the first substrate in a thickness direction of the light-emitting assembly coinciding with a boundary of the light-transmitting area of the first substrate;
a plurality of light emitters in the light guide layer, the plurality of light emitters being configured to project light to illuminate the light-transmitting area;
a touch sensor in the light guide layer, wherein in the thickness direction of the light-emitting assembly, a projection of the touch sensor on the first substrate at least partially overlaps with the light-transmitting area; and
a second reflective layer on a side of the light guide layer away from the first substrate.
