Abstract

The invention provides a pixel driving circuit, a display panel and a pixel driving method which are used for driving a pixel array. The pixel array comprises multiple pixels, wherein each pixel comprises a first subpixel, a second subpixel and a third subpixel which are respectively provided with a storage capacitor, and the adjacent subpixels are opposite in polarity along the row direction. The pixel driving circuit comprises multiple first switching devices; the first switching devices comprise input ends, output ends and control ends; the input end and output end of each first switching device are respectively and electrically connected with the second subpixel and the third subpixel which are in the same row and are opposite in polarity. In a process of driving the first subpixels in a current scanning column, the first switching devices are conducted, so that the second subpixels and the third subpixels are average in voltage, a precharge effect is achieved, the charging time is generally reduced, and the power consumption is reduced.

Description

technical field [0001] The present invention relates to liquid crystal display technology, in particular to a pixel driving circuit, a display panel including the pixel driving circuit and a pixel driving method. Background technique [0002] Currently, a liquid crystal display (LCD, Liquid Crystal Display) is widely used in various electronic devices. A display panel of an LCD is usually composed of a pixel array including a plurality of pixels, and each pixel usually includes a plurality of sub-pixels. When charging a sub-pixel, the corresponding thin film transistor (TFT) of the sub-pixel is first turned on through the corresponding gate line, and then the switching device is turned on so that the data line applies a display voltage to the sub-pixel for charging. When the storage capacitor of the sub-pixel is fully charged, even if the TFT is turned off, the sub-pixel can still work stably due to the display voltage in the storage capacitor. [0003] With the increase o...
