Embodiment Construction

[0020] see figure 1 , figure 1 It is a three-dimensional schematic diagram of the touch display device 1 provided by the present invention. The touch display device 1 includes a cover glass 10 (cover lens / cover glass), a touch module 20 and a display module 30 . The touch module 20 is sandwiched between the cover glass 10 and the display module 30 . In this embodiment, the cover glass 10 and the touch module 20 can be integrated, that is, the cover glass 10 can be used as a substrate of the touch module 20, so that the touch module 20 The touch electrodes are fabricated on the cover glass 10 to form an OGS (one glass solution) or TOL (touch on lens) touch display device. In other embodiments, the touch module 20 may also be glued together with the cover glass 10 and the display module 30 by optical glue. For example, the optical adhesive may be an adhesive with high light transmittance such as optical clear adhesive (Optical Clear Adhesive, OCA) or optical clear resin (Opt...

Abstract

The invention relates to a touch module. The touch module comprises a touch region and a wiring region on the periphery of the touch region. The touch module further comprises a substrate, wherein a first light shielding layer is arranged at a position, corresponding to the wiring region, of the substrate, a conductive signal line is laid above the first light shielding layer and a touch electrode is laid at a position, corresponding to the touch region, of the substrate; a protection pad is further arranged above the first light shielding layer to protect the first light shielding layer, the conductive signal line and the touch electrode are respectively extended to the surface of the protection pad to enable the conductive signal line and the touch electrode to be electrically connected at the position of the protection pad. The invention further provides a manufacturing method of the touch module.

Description

technical field [0001] The invention relates to a touch module and a manufacturing method thereof. Background technique [0002] With the continuous development of electronic technology, most consumer electronic products such as mobile phones, portable computers, personal digital assistants (PDAs), tablet computers, and media players use touch modules as input devices to make the products more user-friendly. machine interaction. [0003] According to different touch principles, touch modules include resistive touch modules, capacitive touch modules, infrared touch modules, and acoustic wave touch modules. Currently, widely used touch modules include resistive, capacitive, optical, and acoustic touch modules. Among them, capacitive touch modules are more widely used. Capacitive touch modules are widely used in various consumer electronics products due to their good touch sensitivity, long service life, and less interference from external signals. [0004] At present, capa...
