Problems solved by technology

[0004] like figure 1 As shown, since the connection part of the existing flexible circuit board 13 connected with the touch panel 120 is linear near the outer edge of the central area 101, and in order to match the shape of the connection end of the flexible circuit board 13, the existing touch panel The edge of the bonding area 103 of the panel 120 close to the central area 101 is also linear, therefore, in the touch panel 120, the space occupied by the bonding area 103 and the flexible circuit board 13 is large, and the flexible circuit board The space between the board 13 and the central area 101 (for example, the distance D) is relatively small. In addition to causing insufficient wiring space for the wiring 123 of the touch panel 120, it may also cause wrinkles and wrinkles in the adhesive layer 14 due to insufficient space. Bubble problem, affecting product yield

Abstract

The invention provides a touch module. The touch module comprises a touch panel and a flexible circuit board; the touch panel defines a central region and a peripheral region surrounding the central region; the flexible circuit board is connected to the peripheral region of the touch panel; the flexible circuit board has an outer edge close to the central region; and at least part of the outer edge is sunken in a direction far away from the central region. The invention furthermore provides the flexible circuit board, the touch panel and an electronic apparatus. According to the touch module,at least part of the flexible circuit board is sunken in the direction far away from the central region, so that the wire arrangement space is expanded, and the influence of the product yield due to the fold and bubble problem of a bonding layer due to insufficient space can be effectively avoided.

Description

technical field [0001] The invention relates to a flexible circuit board, a touch panel, a touch module and an electronic device using the touch module. Background technique [0002] Among the existing electronic devices, taking the touch display device as an example, with the rise of wearable devices, the previous rectangular shape can no longer meet the needs of users. The wearable device may need to be equipped with a non-rectangular display, such as a circular display, a regular triangular display, a regular pentagonal display, a regular hexagonal display, and the like. [0003] Please refer to figure 1 and figure 2 , figure 1 is a schematic plan view of the touch module 12 in the prior art, figure 2 yes figure 1 Enlarged view of middle II. Taking a circular display screen as an example, the touch module 12 includes a touch panel 120 and a flexible circuit board 13 electrically connected to the touch panel 120. The touch panel 120 defines a central area 101 and a...
