1. A display panel, having a display region comprising an optical component setting region, the optical component setting region comprising pixel regions and light transmission regions being provided between adjacent pixel regions of the pixel regions,
wherein the display panel comprises:
pixels located in the display region, wherein each of the pixels comprises a pixel circuit and an organic light-emitting element, the pixel circuit comprises transistors, the transistors comprise a first reset transistor, a second reset transistor, and a drive transistor, wherein the first reset transistor is configured to reset a gate of the drive transistor in response to a scanning signal corresponding to the first reset transistor, and wherein the second reset transistor is configured to reset a first electrode of the organic light-emitting element in response to a scanning signal corresponding to the second reset transistor; and
wherein the pixel circuits of the pixels comprise first pixel circuits located in the optical component setting region, and a gate of the first reset transistor of each of the first pixel circuits is electrically connected to a gate of the second reset transistor of the first pixel circuit.
