Description

technical field [0001] The invention relates to an electronic paper device, a driving circuit and a manufacturing method thereof. Background technique [0002] Generally speaking, the method of driving an active matrix display device is to use a row (column) driver and a column (row) driver and cooperate with timing control to make the display device display image images. [0003] In the row driver, a sample-hold circuit is usually required to convert the sequential pixel data into parallel pixel data and input them into a pixel array. And because it needs to update the image data quickly, a structure similar to Static Random Access Memory (SRAM) is usually used in the sample and hold circuit to achieve the purpose of its fast operation. [0004] Please refer to figure 1 As shown, a general sample-and-hold circuit includes a shift register 11 and a recorder 12, wherein the recorder 12 is composed of four transistors. A pixel data is sent to the pixel array 13 through the ...

Problems solved by technology

[0005] Since each data line needs a recorder 12 to cooperate with the application, when the size of the display device becomes larger and larger, the cost caused by it will become larger and larger, and it will not be economical.
