摘要： A multiplex electrophoretic display driver circuit comprises a memory unit, a display controller and a voltage driving unit. The memory unit has two registers respectively storing the current and former gray-level matrix signals. The gray-level matrix signal contains gray-level data corresponding to electrophoretic pixels. The display controller has an encoding circuit and a counting circuit. The encoding circuit generates a difference-value matrix signal containing difference values according to a difference between the current and former gray-level matrix signals and then generates a voltage-difference matrix signal containing voltage-difference signals corresponding to the electrophoretic pixels. The counting circuit receives the difference-value matrix signal and counts to generate refreshing values corresponding to the difference values. The encoding circuit adds the refreshing values to a next-cycled difference-value matrix signal to generate a new voltage-difference matrix signal. The voltage driving unit drives the electrophoretic pixels according to the voltage-difference matrix signal.

摘要： A driving method of an electrophoretic display having at least a display particle is provided. The driving method includes the following steps. A first voltage difference is applied to a data line in a first period, in which the data line corresponds to one of the display particles. At least a particle restore period is inserted in the first period, and a second voltage difference is applied to the data line in the particle restore periods, in which the second voltage difference is different from the first voltage difference. With this method disclosed here, the maxima brightness, maxima darkness, contrast ratio, color saturation, bistability, and image updating time can be largely improved.

摘要： The present invention is directed to a driving method for compensating the response speed change of an electrophoretic display due to temperature variation, photo-degradation or aging of the display device, without a complex structure (e.g., use of sensors). This is accomplished by combining two waveforms, one of which causes the grey level to become dimmer and the other waveform causes the grey level to become brighter, as the response speed degrades.

摘要： An electro-phoretic display apparatus is disclosed. The electro-phoretic display apparatus has a plurality of pixel units and is coupled to an alternating current (AC) common voltage. The electro-phoretic display apparatus includes a switching unit coupled between a path of a plurality of storage capacitors in the pixel units and the common voltage. The switching unit is turned off according to a control signal before the common voltage carries out a transition action. The switching unit is turned on according to the control signal after the common voltage carries out the transition action.
