The driving method is a representative of an image frame. The image data is written into the electronic paper device 2, wherein the image data has a first sub-image data and a second sub-image resource. It should be noted that the first sub-image data and the second sub-image data are nodes here. It is expressed by the magnitude of the voltage Vpixei. In addition, it is assumed that when the node voltage Vpixel is greater than the first power signal Voi, it is white-face data, and when the node voltage Vpixei is smaller than the first power signal, it is black-face data.

In addition, as shown in FIG. 5, 'it is executed at the first time L' - the red sequence is reset, which first writes the entire display screen to the white-faced material, and then provides the 15V at the second time T22. The first-power signal and the sub-image signal of ον are used to write the _-black pixel data into the corresponding pixels. In order to achieve faster writing speed, the data can be written at the first time T2 "using the large voltage difference (about 20 ν) of the vehicle. (The reaction speed of the general electrophoretic material increases with the write voltage. Increase), for example, the first power signal V01 is -5 V and the node Vpixei is i 5 ν, so that the purpose of increasing the write voltage can be increased without increasing the driving voltage range of the drive 1C. In other words, 'to achieve more The fast write speed of the 'reset procedure' can be greater than the first-writer program, the first-sub-image signal and the first-generation 11 200923534 source signal v01 (or the second power signal v〇2) The difference between the second sub-image signal and the first-power signal V〇1 (or the second power supply number V02) is greater than the first: middle, last, please refer to Figure 6, in order to avoid The attachment to the edge of the electronic paper device 2 can perform a reset procedure in the first time T31, and provide a oscillating signal level; at the second time T32, write the white material; and in the third time Τ33 Write the black-faced information. In this implementation, the signal level of the money refers to the first The power signal or the second power signal has a 汛唬 level. In Figure 6, the power supply 唬V〇i is taken as an example, which is used to generate the first-packet source signal V〇1 and the node voltage %. Fine voltage difference. "Upper 4, because the electronic paper device and its driving system according to the present invention can change the level of the first power signal and cooperate with the first sub-image signal or the second sub-image signal to display the image data. Write each book. The level of the power signal can be changed. Therefore, the driving capability, the driving circuit of 15V can be used to drive the electronic paper device, so that the difficulty of driving the 1C can be reduced, and the cost can be reduced. .卩 is only a gesture, _ is a restrictive.
