[0064] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0065] like Figure 1 As shown, Figure 1This is a flow chart of an electrowetting electronic paper driving method based on AC drive provided by an embodiment of the present application. The method includes but is not limited to step S100, step S200, step S300, step S400, step S500, step S600, step S700, step S800 and step S900:

[0066] Step S100, collecting original image data;

[0067] Step S200, preprocessing the original image data to obtain preprocessed image data;

[0068] Step S300, performing cache processing on the pre-processed image data to obtain cached image data;

[0069] Step S400, performing a read and storage process on the cached image data to obtain stored image data;

[0070] Step S500, performing data compression conversion processing on the stored image data based on a preset electrowetting electronic paper display timing to obtain electrowetting electronic paper display data;

[0071] Step S600, generating an electrowetting electronic paper driving control signal based on the electrowetting electronic paper display data;

[0072] Step S700, obtaining a preset asymmetric AC combined voltage signal;

[0073] Step S800, based on the electrowetting electronic paper driving control signal, synchronously combining the electrowetting electronic paper display data and the asymmetric AC combined voltage signal in a row refresh manner to obtain an asymmetric AC electrowetting electronic paper driving signal;

[0074] Step S900 , driving and controlling the electrowetting electronic paper based on the asymmetric alternating current electrowetting electronic paper driving signal.

[0075] In some embodiments of the present application, in the process of driving the electrowetting electronic paper based on the AC driving mode, firstly, the original image data is collected; then, the original image data is preprocessed to obtain the preprocessed image data; then, the preprocessed image data is cached to obtain the cached image data; then, the cached image data is read and stored to obtain the stored image data; then, based on the preset electrowetting electronic paper display timing, the stored image data is compressed and converted to obtain the electrowetting electronic paper display data; then, based on the electrowetting electronic paper display data, an electrowetting electronic paper driving control signal is generated; then, a preset asymmetric AC combined voltage signal is obtained; finally, based on the electrowetting electronic paper driving control signal, the electrowetting electronic paper display data and the asymmetric AC combined voltage signal are synchronously combined in a row refresh manner to obtain the asymmetric AC electrowetting electronic paper driving signal; finally, based on the asymmetric AC electrowetting electronic paper driving signal, the electrowetting electronic paper is driven and controlled. Through the above technical solution, it is beneficial to improve the effect of the electrowetting electronic paper display, and effectively avoid the problems of screen afterimage and electrowetting ink reflux of the electrowetting video display.

[0076] It is worth noting that the pre-processed image data can be cached using a data cache module, wherein the data cache module can be a first-in, first-out FIFO data cache; the FIFO data cache is a first-in, first-out dual-port buffer, that is, the first data entering it is the first to be removed, one of which is the input port of the memory, and the other port is the output port of the memory; for a single-chip FIFO, there are mainly two structures: a trigger-oriented structure and a zero-oriented transmission structure. The FIFO of the trigger-oriented transmission structure is composed of a register array, and the FIFO of the zero-oriented transmission structure is composed of a dual-port RAM with a read and write address pointer.

[0077] It is worth noting that the cached image data can be stored and processed using a data storage module, wherein the data storage module can be a synchronous dynamic random access memory (SDRAM); synchronous dynamic random access memory is a dynamic random access memory DRAM with a synchronous interface; usually DRAM has an asynchronous interface, so that it can respond to changes in control inputs at any time, while SDRAM has a synchronous interface and will wait for a clock signal before responding to control inputs, so that it can be synchronized with the computer's system bus; the clock is used to drive a finite state machine to perform pipeline operations on incoming instructions, which allows SDRAM to have a more complex operating mode compared to asynchronous DRAM without a synchronous interface.

[0078] It is worth noting that the stored image data is compressed and converted based on the preset electrowetting electronic paper display timing to obtain electrowetting electronic paper display data; wherein the electrowetting electronic paper display data is used to be compatible with the electrowetting electronic paper display.

[0079] It is worth noting that in order for electrowetting electronic paper to realize dynamic video display, a driving signal at a specific frequency is required so that each pixel can be effectively driven, so that the state can be quickly switched according to the driving voltage to realize video and image display with an effective refresh rate. In an embodiment of the present application, display control processing of electrowetting electronic paper is performed based on an asymmetric AC combined voltage signal.

[0080] In addition, in one embodiment, if Figure 2 As shown, the above step S200 may include but is not limited to step S210.

[0081] Step S210 , the original image data is synchronously processed according to a preset system working clock by using a preset synchronization counter and a signal source clock to obtain pre-processed image data.

[0082] In some embodiments of the present application, a preset synchronization counter and a signal source clock are used to synchronize the input raw image data to the system working clock to facilitate subsequent processing and analysis of the data.

[0083] In addition, in one embodiment, the compression algorithm used in the process of performing data compression conversion processing on the stored image data is expressed as follows:

[0088] In addition, in one embodiment, the cropping algorithm used in the process of performing data compression conversion processing on the stored image data is expressed as follows:

[0089]

[0090] Among them, E(x,y) is the pixel data of the electrowetting electronic paper, P(x,y) is the input pixel data, x p andp is the coordinate of the input pixel point, x e and e are the coordinates of the pixels of the electrowetting electronic paper.

[0091] In addition, in one embodiment, if Figure 3 As shown, the electrowetting electronic paper driving control signal includes a resolution driving control signal, a low voltage differential signal, a thin film field effect transistor TFT source voltage control signal, a TFT gate voltage control signal and a TFT common electrode voltage control signal. The above step S600 may also include but is not limited to step S610.

[0092] Step S610, converting the resolution signal of the electrowetting electronic paper display data into a resolution driving control signal, a low voltage differential signal, a TFT source voltage control signal, a TFT gate voltage control signal and a TFT common electrode voltage control signal.

[0093] In some embodiments of the present application, the resolution signal of the electrowetting electronic paper display data is converted into a resolution drive control signal, a low voltage differential signal, a TFT source voltage control signal, a TFT gate voltage control signal and a TFT common electrode voltage control signal to prepare for subsequent electrowetting electronic paper control.

[0094] In addition, in one embodiment, if Figure 4 and Figure 6 As shown, the above step S800 may also include but is not limited to step S810, step S820, step S830 and step S840.

[0098] Step S840: combining the time-synchronized asymmetric AC combined voltage signal with the row data to obtain an asymmetric AC electrowetting electronic paper driving signal.

[0099] In some embodiments of the present application, valid data of a row synchronization signal is determined from a resolution signal of the electrowetting electronic paper display data; then, the valid data of the row synchronization signal is counted by a preset counter to obtain row data; then, the asymmetric AC combined voltage signal and the row synchronization signal are subjected to timing synchronization processing; finally, the timing-synchronized asymmetric AC combined voltage signal and the row data are combined and processed to obtain an asymmetric AC electrowetting electronic paper drive signal; finally, the asymmetric AC electrowetting electronic paper drive signal can be used to control and process the electrowetting electronic paper.

[0100] In addition, if Figure 5 As shown, in one embodiment, the asymmetric AC combined voltage signal includes a positive 15V driving voltage signal and a negative 20V driving voltage signal. The positive 15V driving voltage signal and the negative 20V driving voltage signal form asymmetry, and the positive 15V driving voltage signal and the negative 20V driving voltage signal have the same specific frequency. The asymmetric AC combined voltage signal is controlled by the electrowetting electronic paper driving control signal.
