A pixel charging method and circuit, an LCD panel and an LCD device, wherein two driving signals drive two adjacent row scan lines to charge the pixel. When the pixel of a row is charged, the pixel of the next row is pre-charged, and there is no angle cutting in a certain period before and after the pre-charge is completed, so that after the pre-charge of the pixel is completed and the charging of the pixel starts, the active switch of the pixel is turned on completely without affecting the actual charging process, in order to improve the effect of charging the pixel.
