A liquid crystal display (LCD) panel includes a plurality of pixels, scan lines, data lines crisscrossing with the scan lines, a data driving unit that drives the data lines, an overvoltage driving unit coupled to the data driving unit, a data analysis unit coupled to the overvoltage driving unit and reading gray level of each of sub-pixels, an original overvoltage driving table, and a first overvoltage driving table. Each of the pixels belonging to a same column receives data of a same data line, and each of the pixels includes three sub-pixels controlled by three adjacent scan lines one by one. The original overvoltage driving table and the first overvoltage driving table are coupled to the data analysis unit. When an input signal driving the first overvoltage driving table is same as an input signal driving the original overvoltage driving table, partial voltages driving the data lines and corresponding to the first overvoltage driving table is greater than voltage driving the data lines and corresponding to the original overvoltage driving table. In a same frame image, when gray level of a current sub-pixel is greater than gray level of a previous sub-pixel of a same data line with the current sub-pixel, and gray level difference between the two sub-pixels is greater than a first threshold value, the overvoltage driving unit drives the current sub-pixel according to the first overvoltage driving table.
