Driving method and driving device for liquid crystal display, and liquid crystal display

A driving device of a liquid crystal display, wherein, the driving device comprises a processor and a memorizer, the memorizer stores executable instructions, the processor executes the executable instructions, and the executable instructions comprises:

• a block dividing module, used for dividing first sub-pixels of a display panel into a plurality of array blocks, and selecting at least one of the first sub-pixels in each array block as a glowing pixel;
• a signal acquiring module, used for receiving an image to be displayed, and acquiring a pixel signal of a liquid crystal pixel of the display panel, and looking up a table for the liquid crystal pixel, so as to obtain a high voltage panel driving signal and a low voltage panel driving signal of each first sub-pixel;
• a calculating module, used for calculating a high luminance signal and a low luminance signal, respectively, for driving the glowing pixel in the array block according to the high voltage panel driving signal and the low voltage panel driving signal of the first sub-pixel in each array block;
• and
• a driving module, used for driving the glowing pixels in turn by the high luminance signal and the low luminance signal, and driving other first sub-pixels by the pixel signal.
