Abstract: A display panel includes a front surface, a back surface, a display region, a binding region, a first flexible substrate, and a thin-film transistor. The display region is arranged on the front surface and configured to display a picture. The binding region is arranged on the back surface and at least partially overlaps with the display region. The thin-film transistor layer is arranged on a side of the first flexible substrate close to the front surface of the display panel. The first flexible substrate is arranged between the thin-film transistor layer and the binding region.

Abstract: A display panel and a driving method thereof, and a display device are provided. The display panel includes pixel circuits. Each pixel circuit includes a driving transistor, a data writing circuit, a light-emitting control circuit, a threshold compensation circuit and a bias adjustment circuit. The driving transistor includes a gate electrically connected to a first node, a first terminal electrically connected to a second node, and a second terminal electrically connected to the third node, and is configured to generate a driving current. The third node is connected to a light-emitting element through the light-emitting control circuit. The bias adjustment circuit is configured to provide a signal of a bias adjustment signal terminal to the second node under control of a signal of a first scanning signal terminal in such a manner that a bias state of the driving transistor is adjusted.

Abstract: A display panel and a display device are provided. The display panel is an LTPO display panel including at least one LTPS thin film transistor and at least one Oxide thin film transistor. The LTPS thin film transistor and the Oxide thin film transistor are both formed on the side of the buffer layer facing away from the substrate. A groove structure or a hollow structure is provided on the buffer layer at a position corresponding to the Oxide thin film transistor, and the Oxide thin film transistor is fabricated in the groove structure or the hollow structure, to avoid the case that the great height by which the Oxide thin film transistor protrudes from the substrate causes a great thickness of the LTPO display panel.
