Abstract
A module integrated with an optical sensor, a display panel, and a display apparatus. A light guide plate and the optical sensor are arranged in a thickness direction. A first part of the light guide plate at least partially overlaps the optical sensor in the thickness direction, and a second part does not overlap the optical sensor. A surface that is of the first part and that is away from the optical sensor is a first protrusion structure, and an included angle between at least a partial side edge of the second part and the thickness direction is greater than 0°. In the embodiments of this application, the second part that protrudes from the optical sensor may receive an optical signal around the optical sensor, and enable the optical signal to be totally reflected inside the light guide plate.
