Electronic device

An electronic device, comprising:

• a display module comprising a red-light emitting area, a green-light emitting area, a blue-light emitting area, and a light receiving area, which are spaced apart from each other, the display module further comprising:
• a base layer;
• a display element layer disposed on the base layer and comprising a light emitting element and a light receiving element;
• and
• an input sensing layer disposed on the display element layer,
• wherein the display element layer further comprises:
• a first electrode;
• a hole transport region disposed on the first electrode;
• an electron transport region disposed on the hole transport region;
• and
• a second electrode disposed on the electron transport region,
• wherein the light emitting element comprises a light emitting layer disposed between the hole transport region and the electron transport region,
• wherein the light receiving element comprises a light receiving layer disposed between the hole transport region and the electron transport region and an electron extraction layer disposed on the light receiving layer, and
• wherein the electron extraction layer and light emitting layer do not overlap one another.

An electronic device, comprising:

• a base layer;
• a first electrode disposed on the base layer and comprising a light emitting electrode and a light receiving electrode spaced apart from the light emitting electrode;
• a pixel definition layer disposed on the base layer and including with first and second openings through which the light emitting electrode and the light receiving electrode are exposed, respectively;
• a light emitting layer disposed on the light emitting electrode within the first opening;
• a light receiving layer disposed on the light receiving electrode within the second opening;
• an electron extraction layer disposed on the light receiving layer within the second opening, the electron extraction layer comprises Ca, Yb, K, Cs, Rb, and/or Li;
• a hole transport region disposed between the light emitting electrode and the light emitting layer and between the light receiving electrode and the light receiving layer;
• an electron transport region entirely overlapping each of the pixel definition layer, the light emitting layer, and the light receiving layer;
• a second electrode disposed on the electron transport region;
• and
• an encapsulation layer disposed on the second electrode.
