Abstract: Embodiments of the present disclosure provide a method and apparatus for pixel drive control, a display panel and a storage medium. The method includes generating a drive control signal based on display data of target columns of sub-pixels and corresponding target display brightnesses. The drive control signal includes sub-drive control signals having at least two duty cycles. The method includes controlling a pixel drive circuit to output a corresponding pixel drive signal based on the drive control signal. The pixel drive signal includes sub-drive signals having at least two duty cycles corresponding to respective sub-drive control signals. Embodiments of the present disclosure enables different rows of sub-pixels to be driven by signals having different duty cycles, thereby achieving adjustment of charging time for different rows of sub-pixels, to reduce charging difference for rows of sub-pixels and enable their display brightnesses to become uniform.

Abstract: An array substrate is provided, comprising a display area and a non-display area outside the display area. The non-display area is provided with a first transistor and a first conductive region electrically connected with the first transistor. A control terminal, and one of a source and a drain of the first transistor are both electrically connected to a data line in the display area, the other of the source and the drain of the first transistor is electrically connected to the first conductive region. For this array substrate, the static electricity generated on the data line in the rubbing process can be led to the first conductive region through the first transistor, so as to prevent the static electricity from being transmitted to the display area, which could have destroyed the TFT device in the display area.

Abstract: A backlight module and a liquid crystal display device are disclosed. The backlight module comprises a backlight source, a beam splitter and a light beam conversion portion. The beam splitter converts light from the backlight source into a first and second polarization light beam. The light beam conversion portion converts the first polarization light beam into a third polarization light beam through total reflection, and outputs the second and third polarization light beam through a light exit side. Alternatively, the light beam conversion portion converts the first and second polarization light beam into a fourth and fifth polarization light beam through total reflection, and outputs the fourth and fifth polarization light beam through the light exit side. To this end, light from the backlight source is efficiently applied to irradiate a liquid crystal display panel, and the brightness of the liquid crystal display panel significantly improves.
