摘要： Embodiments of this application provide a display and an electronic device, and relate to the field of display technologies, to improve a problem of large power consumption of a self-luminous display under low-frequency driving. The display includes a plurality of sub pixels, a substrate, a light-emitting device, a pixel circuit, and an isolation portion. The light-emitting device, the pixel circuit, and the isolation portion are disposed on the substrate. The pixel circuit and the light-emitting device are coupled, and are located in the sub pixel. The pixel circuit includes a first transistor and a second transistor. An active layer of the first transistor includes polycrystalline silicon, and an active layer of the second transistor includes a semiconductor oxide. In addition, the isolation portion includes an isolation base and an isolation retaining wall surrounding the isolation base. The active layer of the second transistor is disposed in a groove formed by the isolation retaining wall and the isolation base. The isolation portion is configured at least to block hydrogen ions in the active layer of the first transistor from being diffused into the active layer of the second transistor.
