Abstract: An array substrate, a display device, and a driving method therefor are provided. The array substrate includes multiple pixel units, multiple scan signal lines (2), and multiple data signal lines (3). The pixel units comprise multiple subpixels (10). The subpixels (10) include first sub-subpixels (101) and second sub-subpixels (102). The multiple data signal lines (3) form multiple data signal line sets. The data signal line sets include multiple data signal line subsets. The data signal line subsets include first data signal lines (Sm+1) and second data signal lines (Sm). The first sub-subpixels (101) are connected to the first data signal lines (Sm+1) to acquire a first data signal. The second sub-subpixels (102) are connected to the second data signal lines (Sm) to acquire a second data signal. The voltage of the first data signal is a V. The value interval for the voltage of the second data signal is (0.7a V, a V)∪(a V, 1.3a V). Using the driving method, the display device is provided with a wide viewing angle.

Abstract: Embodiments of the disclosure provide a thin-film transistor, an array substrate, a display panel and a display device. The thin-film transistor includes a current enhancement portion, and the current enhancement portion is provided between a drain and a source. The current enhancement portion may include at least one protrusion portion, and the protrusion portion is provided on the drain and/or the source and faces a channel. The current enhancement portion may include an island portion provided between the drain and the source, and the island portion is separate from the drain and the source. The island portion may include at least one protrusion end, and the at least one protrusion end faces the drain and/or the source.
