1. A display panel, comprising:
a light-guiding component;
a signal transmitter disposed at at least one edge of a first surface of the light-guiding component, wherein a predetermined included angle is defined between the signal transmitter and the first surface of the light-guiding component; and
a sensor array disposed on a side of the light-guiding component and configured to receive and recognize modulated light emitted from the signal transmitter;
wherein a light-emitting surface of the signal transmitter is provided with a light-controlling component configured to adjust a light-emitting angle of the signal transmitter, and the modulated light emitted from the signal transmitter has a total reflection in the light-guiding component;
wherein the display panel further comprises a middle frame, an end of the middle frame near the light-guiding component is provided with a recess configured to fix and support the light-guiding component, and the signal transmitter is disposed on the middle frame; an orthographic projection of the signal transmitter on the light-guiding component is located at an orthographic projection of the recess on the light-guiding component; and
wherein the display panel further comprises an ink layer disposed between a side of the middle frame facing the light-guiding component and a second surface of the light-guiding component, and the second surface is inclined to the first surface.
