Problems solved by technology

like figure 1 Shown is a schematic diagram of a two-layer stacked structure of a touchpad of a notebook computer with a near field communication coil, wherein the near field communication coil 101 is disposed under a substrate 103, and the first layer 1031 of the substrate 103 is provided with driving conductor lines and sensing conductor lines , and the second layer 1032 of the substrate 103 is provided with circuit components and wiring. With this configuration, since there is no shield between the near field communication coil 101 and the substrate 103, the touch panel is greatly interfered by the near field communication signal, and It will affect the function of the touchpad, so this configuration is not suitable for the application of the NFC coil 101 under the touchpad
[0004] Therefore, the structure of the existing touch panel still has imperfections, and there is a need to improve it.

Abstract

A touchpad device comprises a near-field communication coil, a shielding layer and a touch layer. The near field communication coil is provided with two opposite first edges and two opposite second edges; the shielding layer is arranged on the near-field communication coil, and a plurality of slits are formed in the shielding layer; the touch layer is arranged on the shielding layer; the touch layer is provided with a plurality of first conductor wires which are arranged at intervals and a plurality of second conductor wires which are arranged at intervals, wherein the plurality of first conductor wires and the plurality of second conductor wires are crossed at intervals, each slit is arranged along one first conductor wire and strides over two second edges of the near field communicationcoil, and each slit at least exceeds the near field communication coil by a length which is greater than the diameter width of the near field communication coil on the two second edges.

Description

technical field [0001] The invention relates to the technical field of touch panels, in particular to a touch panel device with a near-field communication function and a notebook computer including the touch panel device. Background technique [0002] Touch pads have gradually become standard equipment on various consumer electronics products and computer devices. For example, today's notebook computers are equipped with touch pads to provide users with another input besides mouse and keyboard. Function. In addition, the notebook computer can be configured with a Near-Field Communication (NFC) coil for data transmission with an external NFC object such as a NFC card or a mobile phone supporting the NFC function. For example, the user can first use a laptop to search for data, and after finding a correct URL and copying the URL, then put a mobile phone that supports NFC close to the NFC coil of the laptop, so that the laptop can pass the NFC The field communication data tra...
