Organic electroluminescent display device

An organic electroluminescent display device, comprising:

• an organic light emitting structure, comprising:
• a first electrode;
• a second electrode, disposed oppositely to the first electrode;
• an organic light emitting layer, disposed between the first electrode and the second electrode;
• and
• a photo current sensitive layer, disposed between the organic light emitting layer and the first electrode;
• a back light module, disposed correspondingly to the organic light emitting structure, the back light module configured to provide a light beam to the organic light emitting structure;
• wherein the photo current sensitive layer is configured to absorb the light beam for generating an electrical current, and the electrical current is configured to drive the organic light emitting layer;
• and
• a light control structure, disposed between the organic light emitting structure and the back light module, wherein the light control structure is configured to control amount of the light beam entering the organic light emitting structure.
