  • Patent number: 9784997
    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).
