Problems solved by technology

[0003] However, according to the metal contacts and related circuit configurations of existing touch screens, each touch electrode must be provided with a dedicated set of wires and metal contacts to export its touch signals, but this design will lead to the loss of the wires and metal contacts. Occupying too much area is not conducive to the volume reduction of the touch panel module and the flexible circuit board, and will limit the adjustment flexibility of the circuit configuration

no. 1 example

[0024] refer to figure 1 and figure 2 , is the first preferred embodiment of the touch panel module 100 of the present invention. The touch panel module 100 can be applied to various electronic devices such as mobile phones and tablet computers, and is not limited to specific application forms.

[0025] The touch panel module 100 of this embodiment includes a substrate 1, a shielding layer 2, a first sensing unit 3, at least one (here three, but not limited to) second sensing unit 4, a The overlapping portion 5 and a connecting portion 6 form an electrical connection with an external circuit (not shown) through a flexible circuit board 101 .

[0026] The substrate 1 has light transmission and is divided into a visible area 11 and a non-visible area 12 adjacent to the visible area 11 , which can be made of glass material, but not limited thereto.

[0027]The shielding layer 2 is arranged on the non-visible area 12 of the substrate 1, and can be made of materials with light-...

[0034] refer to image 3 , is the second embodiment of the touch panel module 100 of the present invention. The touch panel module 100 of this embodiment is substantially the same as the aforementioned first embodiment, the main difference lies in the implementation of the connecting portion 6 .

[0035] In this embodiment, the connecting portion 6 further includes at least one (here, two are used as an example, but not limited thereto) first insulating layer 62, and the circuit wiring method of the first wire 52 and the first sub-wire 61 is the same as the aforementioned The first embodiment is different. Specifically, the first wires 52 extend between the first electrode 31 and the first sub-electrode 41, and the first sub-wires 61 cross the first wires 52 in an electrically insulated manner to electrically insulate Connect to the first wire 52 to which it belongs. The first insulating layer 62 is respectively arranged at the overlapping positions of the first wires 52 an...

[0039] refer to Figure 4 , Figure 5 , is the third embodiment of the touch panel module 100 of the present invention. The touch panel module 100 of this embodiment is substantially the same as the aforementioned first embodiment, the main difference lies in the implementation of the sensing electrode structures of the first sensing unit 3 and the second sensing unit 4 .

[0040] In this embodiment, the first sensing unit 3 and the second sensing unit 4 respectively have a biaxial sensing electrode structure, so the first sensing unit 3 also includes at least one (here five are taken as an example, but not limited to this) The second electrode 32 and a second insulating layer 33, and the second sensing unit 4 also includes at least one (here three are used as an example, but not limited to) second sub-electrode 42 and a third insulating layer 43 . Therefore, both the overlapping portion 5 and the connecting portion 6 that provide the function of the conductive circuit have...

Abstract

For a touch panel module, a first sensing unit is disposed on a viewing area of a substrate and includes a first electrode, a second sensing unit corresponds in position to a non-viewing area of the substrate and includes a first sub-electrode, an attaching portion corresponds in position to the non-viewing area and includes a first contact, and a first conducting wire, two ends of which are respectively connected to the first electrode and the first contact to form an electrical connection therebetween, and a connecting portion corresponds in position to the non-viewing area and includes a first conducting sub-wire for forming electrical connection between the first electrode and the first sub-electrode.

Description

technical field [0001] The present invention relates to a touch panel module, in particular to a touch panel module with optimized design for internal circuit configuration. Background technique [0002] Currently common touch screens, such as Patent No. TW I380071, include components such as a liquid crystal module (LCM for short), a touch panel module (TPM for short), and the like. Among them, the touch panel module is usually electrically connected to a flexible printed circuit (FPC) and connected to an external control circuit through the flexible printed circuit for transmission of touch signals and correlation. control. Based on the current circuit design of the touch panel module and the flexible circuit board, the touch panel module will be provided with a plurality of metal contacts corresponding to its touch electrodes (such as ITO electrodes), and each metal contact is used for touch control. The electrodes are connected to each other through metal wires in a on...
