Display panel and terminal device

A terminal device, comprising:

• a display panel with a light-transmitting hole, a display area located outside the light-transmitting hole, a peripheral area located outside the display area and a transition area located between the light-transmitting hole and the display area, comprising:
• a driving backplane;
• a barrier dam, disposed on the driving backplane, located in the transition area, and at least surrounding a partial area of the light-transmitting hole;
• a first separation component, disposed on the driving backplane and located in the transition area, wherein the first separation component and the barrier dam are distributed at intervals in a radial direction of the light-transmitting hole, the first separation component comprises a first separation pillar at least surrounding the partial area of the light-transmitting hole, and a sidewall of the first separation pillar is provided with a cut-off groove at least surrounding the partial area of the light-transmitting hole;
• a light-emitting device, disposed on a side of the driving backplane and located in the display area;
• a photoelectric sensing device, disposed between the barrier dam and the first separation component;
• and
• an encapsulation layer, covering the light-emitting device, the barrier dam and the first separation component, wherein the encapsulation layer comprises an organic layer defined on a side of the barrier dam away from the light-transmitting hole;
• and
• a photosensitive element, disposed on a side of the driving backplane away from the light-emitting device and overlapped with the light-transmitting hole.
