Abstract: 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.

Abstract: A method for obtaining a backlight intensity may improving data processing speed of a display device. The method includes: dividing image data into N sets of data; calculating a backlight intensity of each backlight block according to a corresponding set of data; for each group of pixels, calculating a backlight intensity corresponding to a first pixel according to a backlight intensity of each effective backlight block corresponding to the first pixel and a backlight diffusion weight of the effective backlight block corresponding to the first pixel; calculating backlight intensities corresponding to second to Mth pixels in the Tth group of pixels according to the backlight intensities corresponding to first pixels in the Tth group of pixels and a (T+1)th group of pixels; and for a Nth group of pixels, setting the backlight intensity corresponding to the first pixel as backlight intensities corresponding to second to Mth pixels.
