1. An under-display camera structure, comprising: a display and a camera arranged under the display, wherein the display comprises display glass and display area backlight, an opening area is configured in the display area backlight above the camera, the display glass forms convex glass in a direction of the opening area curving towards the camera, a flexible printed circuit board having an annular conical structure is connected between the convex glass and the camera, so as to surround a viewing angle of the camera, and a plurality of lamp beads are sequentially arranged on the flexible printed circuit board from a camera end to a convex glass end, wherein
when the camera is in a turned-on state, a first-type lamp bead which is pre-determined in the plurality of lamp beads and is close to the camera end is in a turned off state, a predetermined second-type lamp beads far away from the camera are in a lighting state, and light emitted by the second-type lamp beads forms a circle of light on the convex glass after being refracted by the convex glass, so as to make the convex glass display no images; and
when the camera is in a turned-off state, the plurality of lamp beads are in a lighting state, and backlight is provided for the convex glass after refraction by the convex glass, so as to make the convex glass display images.
