    Abstract: Provided are a driving method and a driving apparatus for a display device, and a display device. The driving method includes inputting a gate driving signal to each gate line progressively, and inputting a gate driving signal to one gate line within each scanning period; inputting a data signal to each data line within each scanning period, and inverting, for one time, polarity of a data signal inputted to the same data line every n scanning periods; and inputting a threshold voltage with a preset time length to a threshold voltage line within each scanning period, latching the data signal inputted to the data line when a threshold voltage is inputted to the threshold voltage line, and outputting the data signal otherwise; wherein the second time length is greater than the first time length.

    Abstract: Disclosed are a backlight module and a display device having the same. The backlight module includes an optical assembly including a light guide plate, a plastic frame and an optical film disposed on a light-emitting side of the light guide plate. The plastic frame includes a side wall and a bearing portion formed on the top of the side wall of plastic frame and located on the light-emitting side of the light guide plate, the side wall of plastic frame is arranged to surround the light guide plate, the bearing portion extends from the top of the side wall of plastic frame to the light guide plate, and a side surface of the bearing portion faces a side surface of the optical film. The backlight module according to the disclosure can reduce the optical retardation of the display device, thereby reducing the dark-state light leakage of the display device.
