摘要： A shift register, a gate drive circuit, a display device, and a driving method for the same. The shift register comprises a first output sub-circuit, which provides, under control of an INPUT or a RESET, a signal of a CN or a CNB to a pull-up node, outputs, according to a voltage level of the pull-up node, a signal of a CK to an OUT, transmits, under control of a CKB, a CKB to a pull-down node, and pulls down, according to a voltage level of the pull-down node, a voltage level of the OUT; a second output sub-circuit, which outputs, during a scan output stage and under control of a GON, a signal of the OUT to a GOUT; and a transfer sub-circuit, which pulls down, during a scan transfer stage and under control of a GOFF, a voltage level of the GOUT.

摘要： A display device and a method for driving the display device are described, where the display device includes a plurality of pixel island groups, a plurality of lenses, a positioning module, and a gate driving chip. The plurality of pixel island groups are arranged in array, wherein each of the pixel island groups includes a plurality of pixel islands, and different pixel islands are able to be scanned in different scanning modes. The positioning module is configured to determine a gaze area and a non-gaze area according to gazed coordinates of human eye. The gate driving chip is configured to provide gate driving signals in a first driving manner to sub-pixel units in the gaze area, and provide gate driving signals simultaneously in a second driving manner to sub-pixel units in the non-gaze area during a scanning stage of the sub-pixel units in the non-gaze area.
