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.

An embodiment of the invention provides a driving method for a display unit, wherein the display unit includes a first electrode, and a second electrode disposed opposite to the first electrode, wherein the first electrode is separated from the second electrode by a distance, and a first particle with a polarity is distributed between the first electrode and the second electrode. The driving method includes the steps of: casting a first voltage difference between the first electrode and the second electrode to make the first particle move toward the second electrode; stopping casting of the first voltage difference; and casting a second voltage difference between the first electrode and the second electrode to apply an opposite force to the first particle, wherein the polarity of the second voltage difference is different from that of the first voltage difference.

An electrophoretic display device is provided. The display device includes a first substrate, a second substrate opposite to the first substrate, a plurality of particles disposed between the two substrates, a driving circuit and a sensor. The driving circuit is configured for a display mode by imagewise driving the particles to display one or more images and configured for an idle mode by causing the particles to move away from at least one of the two substrates and to be non-imagewise dispersed in between the two substrates so as to form a substantially non-imagewise bistable state between the two substrates in the idle mode. The sensor senses or detects the usage status of the display device or the environmental parameters associated with a surrounding environment. The driving circuit is configured for either the display mode or the idle mode in accordance with the usage status or the environmental parameters.
