Embodiment Construction

[0102] Hereinafter, several examples are presented to illustrate the present invention, but the present invention is not limited to the illustrated examples. Appropriate combinations are also allowed between the embodiments. As used throughout the specification of this application, including the claims, the term "coupled" may refer to any means of connection, direct or indirect. For example, if it is described in the text that a first device is coupled to a second device, it should be interpreted that the first device can be directly connected to the second device, or the first device can be connected through other devices or some kind of connection means. indirectly connected to the second device. Additionally, the term "signal" may refer to at least one current, voltage, charge, temperature, data, electromagnetic wave, or any other signal or signals.

Abstract

The invention provides a touch sensor for sensing a touch object. The touch sensor comprises a sensing element and a sensing circuit, wherein the sensing element comprises a substrate, a sensing electrode, a sensing common electrode and a shielding layer; the sensing electrode and the sensing common electrode are arranged on the substrate; the shielding layer is disposed on the sensing electrode and the sensing common electrode; the sensing circuit is electrically connected to the sensing element; the sensing circuit includes a resistive element; the relaxation frequency of the relaxation signal of the touch sensor depends on the resistance value of the resistance element and / or the parasitic resistance value of the sensing element; and the pulse wave variation value of the relaxation signal is changed by touching an object. The touch object is a conductor. In addition, the invention also provides an electronic paper display panel and an electronic paper display device comprising the touch sensor.

Description

technical field [0001] The present invention relates to a sensor, a display panel and a display device, in particular to a touch sensor, an electronic paper display panel and an electronic paper display device. Background technique [0002] In recent years, electronic paper display devices have been widely used in electronic readers (such as e-books, electronic newspapers) or other electronic components (such as electronic tags) due to their advantages of thinness, durability, energy-saving and environmental protection, and low power consumption. ). On the other hand, if the electronic paper display device has a touch sensing function, it will provide an intuitive input method for the user and improve the user experience. [0003] Generally speaking, the touch sensor must be exposed to the air, and its internal layered structure should not include, for example, an Indium Tin Oxide (ITO) conductive film or other similar conductive layers to avoid covering other The layered ...
