Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Before describing the embodiments of the present invention in detail, a conventional touch device with an arc-shaped edge (hereinafter referred to as an arc-shaped touch device) and a bonding area of a flexible circuit board thereof will be described.
Fig. 1 shows a schematic diagram of a bonding area of a conventional arc-shaped touch device, and referring to fig. 1, the arc-shaped touch device includes an effective touch area 10 and an edge area 20, wherein a bonding area 21 of a Flexible printed circuit Board (FPC) for bonding a touch chip is located in the edge area 20, and the bonding area 21 is provided with a plurality of bonding terminals 01 for bonding the Flexible circuit Board.
In addition, in the case that the arc-shaped touch device is matched with a display device, 30 shown in fig. 1 is a flexible circuit board for binding the display driver chip, and generally, the flexible circuit board may bind the display driver chip in a cop (chip On pi) manner, so that the display driver chip may be disposed On the back surface of the arc-shaped touch device. In practical applications, in order to reduce the frame of the whole device, the bonding area of the flexible circuit board of the display driver chip and the bonding area of the flexible circuit board of the touch chip may be disposed at different sides of the edge area 20, for example, as shown in fig. 1, the bonding area of the flexible circuit board of the display driver chip may be disposed in a 6 o 'clock direction of a product, and the bonding area of the flexible circuit board of the touch chip may be disposed in a 9 o' clock direction of the product. Of course, the binding region of the display driver chip flexible circuit board may be set in the 6 o 'clock direction of the product, the binding region of the touch chip flexible circuit board may be set in the 12 o' clock direction of the product, and so on.
Generally, as shown in fig. 1, the plurality of binding terminals 01 are generally arranged in a straight line, that is, the plurality of binding terminals 01 are arranged in a matrix. As shown in fig. 1, the binding region 21 is also set to be rectangular correspondingly to the arrangement mode of the parallel linear arrangement. For the arc-shaped touch device, the rectangular bonding area 21 is relatively protruded with respect to the arc-shaped edge of the arc-shaped touch device, and there is a protruded end.
Referring to fig. 1, O is a geometric center point, i.e., a center of a circle, of the arc-shaped effective touch area 10 in a direction parallel to the arc-shaped touch panel, a is a width occupied by the plurality of binding terminals 01, B is a distance between a maximum protrusion of the binding area 21 and the effective touch area 10, hereinafter referred to as a hypotenuse frame, and C is a distance between the minimum protrusion of the binding area 21 and the effective touch area 10, hereinafter referred to as a straight-side frame. As shown in fig. 1, the straight-line parallel arrangement of the binding terminals 01 may make the oblique-side frame B of the binding region 21 larger, and the oblique-side frame B directly affects the size of the touch device housing, because the touch device housing needs to cover the binding region 21 so that the binding region 21 is not visible from the outside, and the larger binding region 21 of the oblique-side frame B may cause the size of the touch device housing to be wider, which is not favorable for realizing the narrow-frame configuration of the touch device. Therefore, for the arc-shaped touch control product, the bevel edge frame B is an important parameter for the overall design.
In summary, the touch device, the touch display device and the wearable device in the embodiments of the present invention are provided for the existing arc-shaped touch device and the binding region of the flexible circuit board therein, so as to solve the problem that the binding region of the existing arc-shaped touch device is wide, which results in a wide frame of the touch device housing covering the binding region, and is not beneficial to realizing a narrow frame of the touch device.
