The invention relates to a driving method and system for increasing the display gray level of electrowetting electronic paper, and the method comprises the steps: supposing that the maximum data bit, capable of achieving digital-to-analog conversion, of an existing driving chip is m, in order to achieve the conversion of more bits, if the target data bit of gray level reduction is n, the target data bit is divided into (h + 1) m-bit data + k values, and the m-bit data + k values are output in different subframes; wherein the first m-bit data corresponds to the low m-bit data of the n-bit data, and the value of the first m-bit data is output in the first subframe; for the ith bit in the n-bit data, igt; if the bit is 0 or 1, correspondingly using 2i-m-1 subframes to output 2i-m-1 m-bit all-0 or all-1 data according to the bit of 0 or 1; the gray scale data corresponding to the k value is output by one subframe, all subframes are combined to output (h + 2) subframes, and 2n gray scales are formed, so that the d
