A method of programming a driving waveform for an electrophoretic display (EPD) is provided, wherein the driving waveform includes several single pulses selected from K candidate pulse widths W1˜WK. First, K different constant pulse sequences corresponding to W1˜WK may be applied to the EPD, to obtain K sets of discrete electro-optical response data. A polynomial curve fitting algorithm is applied to obtain K relation curves C1˜CK between contrast ratios of the EPD to time, corresponding to the K sets of discrete electro-optical response data. After calculating the slope values S1˜SK of the curves C1˜CK at a current contrast ratio of the EPD, a maximum slope Smax among S1˜SK and a specific pulse width Ws corresponding thereto are determined. A next contrast ratio of the EPD is calculated according to Ws and Smax. The design process is repeated until the next contrast ratio of the EPD exceeds a target value.
