Print recognition module and display device

A display device, comprising:

• a print recognition module;
• and
• a display panel on a light incident side of the print recognition module;
• wherein the print recognition module comprises:
• a light guide structure;
• wherein the light guide structure comprises:
• a light guide plate;
• and
• an optical path adjusting component;
• wherein the light guide plate comprises a light incident surface and a light emergent surface arranged oppositely, and side surfaces connected between the light incident surface and the light emergent surface;
• a first optical sensor at a side of the light emergent surface of the light guide plate;
• and
• at least one second optical sensor corresponding to at least one of the side surfaces of the light guide plate;
• wherein
• the optical path adjusting component is disposed between the side face of the light guide plate and the second optical sensor, and comprises a reflector, wherein
• an included angle between the reflector and the light incident surface of the light guide plate is an acute angle;
• and
• the reflector reflects at least part of light incident from a light incident side of the light guide plate to the second optical sensor.
