OLED light source, display device and method for fabricating the same

A display device, comprising an OLED light source, wherein the OLED light source comprises:

• light emitting units, comprising anodes arranged in an array;
• metal wires, connecting the anodes and disposed between the light emitting units;
• a photosensitive sensor, disposed on the metal wires which makes the metal wires as a sense electrode of the photosensitive sensor;
• a drive electrode, provided on the photosensitive sensor;
• and
• an opening, disposed at a position where the metal wires correspond to the drive electrode,
• wherein the photosensitive sensor is configured to receive an external light signal through the opening.
