Embodiment Construction

[0034] Please refer to Figures 1 to 3a , The first embodiment of the touch panel of the present invention includes: a touch detection substrate 10 and a flexible circuit board 20 .

[0035] The touch detection substrate 10 can be flexible and has a first fixed edge 11 . At least one first engaging slot 100 is formed on the first fixing edge 11 . At least one first peripheral region (or called a routing region) 13 adjacent to the first fixed edge 11 is disposed on the touch detection substrate 10 . In addition, the width W of the first fitting groove 100 is greater than 0.8 mm, and the depth L1 of the first fitting groove 100 is greater than 1.0 mm. Furthermore, the first engaging slot 100 is U-shaped. In addition, a plurality of first receiving metal pads (Receiver Pad, Rx Pad) located in the first peripheral area 13 on the right side of the first fitting groove 100 and a plurality of first metal pads located in the first A plurality of first transmitting metal pads (Tran...

Abstract

A touch panel, comprising: a touch detection substrate having a first fixed edge, at least one first peripheral region adjacent to the first fixed edge is arranged on the touch detection substrate, and the first At least one first fitting slot is formed on the fixed edge; and a flexible circuit board is fixed to the touch detection substrate and has a second fixed edge, and at least one The second peripheral region adjacent to the second fixed edge, wherein the second fixed edge of the flexible circuit board is embedded in the first fitting groove of the touch detection substrate. The touch detection substrate can obtain a better configuration of the second peripheral region due to the omission of the fitting groove.

Description

technical field [0001] The invention relates to a touch panel. Background technique [0002] The touch panel is an indispensable basic component of mobile devices such as smart phones or tablet computers, which allows users to perform single-point or multi-point touch. Touch detection substrate and flexible printed circuit (FPC) are common components on the touch panel. The touch detection substrate is embedded on the touch screen panel for users to perform single-point or multi-point touch operation, and the flexible circuit board can be connected to an external circuit board. [0003] However, in the assembly structure of the touch detection substrate and the flexible circuit board on the existing touch panel, the circuit layout on the flexible circuit board needs to accommodate the slot and bypass the slot because of the slot on the flexible circuit board, or It is a problem of breaking into multiple segments or increasing the size of the flexible circuit board.
