A liquid crystal panel includes a plurality of thin film transistors (TFTs), scan lines, data lines, a scan driving chip, and a data driving chip. The scan driving chip includes a compensation driving unit coupled to the scan lines. The compensation driving unit drives the TFTs corresponding to a next-row of scan line to turn on when the scan driving chip drives the TFTs corresponding to a current-row of scan line to turn on or after the scan driving chip drives the TFTs corresponding to the current-row of scan line to turn on. The compensation driving unit drives the TFTs corresponding to the next-row of scan line to turn off when the TFTs corresponding to the current-row of scan line receive a data signal of the data driving chip or before the TFTs corresponding to the current-row of scan line receive the data signal of the data driving chip.
