[0003] It is true that the above-mentioned e-books have many characteristics and advantages that traditional paper does not have. However, when changing screens, they are still controlled by key operations, which is not very convenient. Although some e-books are equipped with a touch panel to provide more convenience. However, the touch panel is externally assembled and stacked on the outermost side of the e-book. Because it has glass substrates and other components, it will increase the overall thickness and weight of the e-book and affect the optical display of the e-book. effect

Abstract

The invention relates to a touch detection circuit structure for a bistable electronic display, which is arranged between a substrate and a bistable display thin film. The touch detection circuit structure comprises a plurality of first electrodes, an insulation layer and a plurality of second electrodes, wherein the insulation layer is provided with a plurality of perforations; openings at both ends of each of the perforations are corresponding to the first electrode and the second electrode respectively; and the second electrode does not cover the perforations completely. Under the touch action of external, the first electrodes contact the second electrodes to generate resistance impedance effect for detecting and judging the position of touch points by a system end of the display.

Description

technical field [0001] The present invention is related to optical displays, and more specifically refers to a touch detection circuit structure for bistable electronic displays. Background technique [0002] The development of e-book (E-Paper Display) imitates the appearance of ink on paper, making it easy to read, easy to carry, reusable, and downloadable to update data. When using e-books, only when the screen changes In other words, when people read the information on the display screen, the power is turned off, so the power consumption can be reduced; secondly, the structural design of the e-book does not need to be equipped with a backlight source and can be read with only external ambient light, reducing cost. [0003] It is true that the above-mentioned e-books have many characteristics and advantages that traditional paper does not have. However, when changing screens, they are still controlled by key operations, which is not very convenient. Although some e-books ...
