1. A display panel, comprising: a display region, wherein the display region comprises GaN-based LED units arranged in an array, the display region comprises a first-selected region, the first-selected region comprises a capturing-visible-light-image state comprising a state of real-time viewing before capturing and a capturing-image state; at the state of real-time viewing before capturing, some GaN-based LED units in the first-selected region are used for real-time viewing before capturing, and at the capturing-image state, all of the GaN-based LED units in the first-selected region are used for capturing an image;
wherein each of the GaN-based LED units comprises GaN-based LED structures used for sensing light and emitting light;
wherein each of the GaN-based LED structures comprises a red-light photosensitive and emitting layer, a green-light photosensitive and emitting layer, a blue-light photosensitive and emitting layer and an infrared photosensitive and emitting layer which are stacked from up and down; materials of the red-light photosensitive and emitting layer, the green-light photosensitive and emitting layer, the blue-light photosensitive and emitting layer and the infrared photosensitive and emitting layer are GaN-based materials containing different proportions of In; when the red-light photosensitive and emitting layer, the green-light photosensitive and emitting layer, the blue-light photosensitive and emitting layer and the infrared photosensitive and emitting layer are used for sensing light, photosensitive charges are generated based on wavelengths of received light, or not generated based on wavelengths of received light; and when the red-light photosensitive and emitting layer, the green-light photosensitive and emitting layer, the blue-light photosensitive and emitting layer and the infrared photosensitive and emitting layer are used for emitting light, light with different wavelengths and different strengths is generated based on different values of applied voltages.
