摘要： Embodiments of this application provide a flexible display screen and a display terminal, and relate to the field of display technologies, to reduce a probability that a stress concentration problem occurs because a non-luminous area of a display screen is folded a plurality of times. A back surface of the flexible display screen is connected to a first housing, a second housing, and a rotating shaft that are included by a support component. A part that is of the flexible display screen and that is connected to the rotating shaft is used as a first bent portion. The first bent portion is bent along an axis of the rotating shaft, to fold in half a part that is of the flexible display screen and that is separately connected to the first housing and the second housing. The flexible display screen includes a first peripheral portion and a second peripheral portion. The first peripheral portion and the second peripheral portion are in the non-luminous area, and are disposed side by side on a same side of a luminous area. A part that is of the first peripheral portion and that is bent to the back surface of the flexible display screen faces the first housing. A part that is of the second peripheral portion and that is bent to the back surface of the flexible display screen faces the second housing. A first notch is in the non-luminous area, disposed on a side of the first bent portion, and located between the first peripheral portion and the second peripheral portion.

摘要： A display module and a display apparatus are provided. The display module includes a polygonal display region (1) and a plurality of non-display portions (21). The non-display portions (21) are connected to side edges of the display region (1) in a one-to-one correspondence. At least two of the non-display portions (21) are bent to a back side of the display region (1). When the non-display portions (21) bent to the back side of the display region (1) include adjacent non-display portions (21), there may be an opening (7) between two adjacent non-display portions (21). In this solution, it is convenient to reduce pulling force between the adjacent non-display portions (21), and stress concentration may be reduced after the adjacent non-display portions (21) are bent to the back side of the display region (1). Specifically, the non-display portion (21) is provided with a signal line (22), and signal lines (22) of the adjacent non-display portions (21) are electrically connected by using a connecting line (11). The connecting line (11) is used to connect the signal lines (22) of the adjacent non-display portions (21). In this solution, the connecting line (11) is disposed on the back side of the display region (1), so that the signal lines (22) of the adjacent non-display portions (21) can be electrically connected, to control the display module to display a picture.

摘要： A flexible display module and a flexible display apparatus are provided. The flexible display module includes a cover (210), a flexible display panel (220), a rigid backplane component (230), and an optical device (240) that are sequentially disposed, and the optical device (240) is disposed on a side that is of the rigid backplane component (230) and that is away from the flexible display panel (220). The rigid backplane component (230) includes a rigid backplane body (231) and a rigid light-transmitting component (232). The rigid light-transmitting component (232) is disposed between the optical device (240) and the flexible display panel (220), and the rigid light-transmitting component (232) has a light transmission feature and is rigid. Therefore, light can penetrate through the rigid light-transmitting component (232) and enter the optical device (240), so that the optical device (240) operates normally. In addition, the flexible display panel (220) and the optical device (240) may be further isolated from each other. Even if a user presses the flexible display panel (220) when using the flexible display module, because there is a rigid support structure, neither the flexible display panel (220) nor the optical device (240) is easily damaged, to improve quality and a service life of the flexible display module.

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.
