The present invention relates to an electrophoresis display device and a method of driving the same, capable of improving display quality by reducing the update time of an image and enhance grayscale expression. The method of driving the electrophoresis display device according to the embodiment of the present invention includes the steps of designing a plurality of waveforms including sub-frames in which only image data to make voltage, which is applied to a pixel by data voltage for the change from a present image to a next image and common voltage, to become 0V or more or to become 0V or less; selecting a waveform for the update of the next image among the waveforms based on the input image data; and supplying common voltage of 0V or -XV to the whole pixels if the image data of the sub-frame is formed such that the voltage applied to the pixel becomes 0V or more, and supplying the common voltage of 0V or +XV to the whole pixels if the image data of the sub-frame is formed such that the voltage applied to the pixel becomes 0V or less, wherein voltages corresponding to -2X, -X, 0, +X, and +2X are applied to the whole pixels, thereby updating the next image. [Reference numerals] (AA) Start; (BB) End; (S10) Design waveform to maximize sub-frame having image data of more than 0 (+1, 0) or less than 0 (-1, 0).; (S20) Loading waveform suitable for change of screen image.; (S30) Generate common voltage of +15V, 0V, or -15V according to image data.; (S40) Generate Vcom of -15V if image data is more than 0 (+1, 0).; (S50) Generate Vcom of +15V if image data is more than 0 (-1, 0).; (S60) Generate voltages of pixel corresponding to -30V, -15V, 0V, +15V, and 30V and drive data update at five level. |
