Detailed Description
In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description.
Before describing the embodiments of the present invention in detail, an existing touch device with an arc edge (hereinafter referred to as an arc touch device) and a binding area of a flexible circuit board therein will be described.
Fig. 1 shows a schematic diagram of a binding area of an existing arc-shaped touch device, referring to fig. 1, the arc-shaped touch device includes an effective touch area 10 and an edge area 20, wherein a binding area 21 for binding a flexible circuit board (Flexible Printed Circuit Board, FPC) of a touch chip is located at the edge area 20, and the binding area 21 is provided with a plurality of binding terminals 01 for binding 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 driving chip, and in general, the flexible circuit board may bind the display driving chip in a manner of COP (Chip On Pi), etc., so that the display driving chip may be disposed on the back of the arc-shaped touch device. In practical application, in order to reduce the frame of the whole machine, the binding area of the flexible circuit board of the display driving chip and the binding area of the flexible circuit board of the touch chip may be disposed on different sides of the edge area 20, for example, as shown in fig. 1, the binding area of the flexible circuit board of the display driving chip may be disposed in the 6 o 'clock direction of the product, and the binding area of the flexible circuit board of the touch chip may be disposed in the 9 o' clock direction of the product. Of course, the binding area of the flexible circuit board of the display driving chip is set in the 6 o 'clock direction of the product, the binding area of the flexible circuit board of the touch chip is set in the 12 o' clock direction of the product, and the like.
In general, as shown in fig. 1, a plurality of binding terminals 01 are generally arranged in a parallel manner in a straight line, that is, a plurality of binding terminals 01 are arranged in a straight line according to a matrix arrangement. As shown in fig. 1, the binding areas 21 are also arranged in a rectangular shape corresponding to the in-line parallel arrangement. For an arc-shaped touch device, the rectangular binding area 21 protrudes relatively to the arc-shaped edge of the arc-shaped touch device, and a protruding end exists.
Referring to fig. 1,O, the geometric center point of the arc-shaped effective touch area 10, i.e. the center of a circle, a is the width occupied by the binding terminals 01 in the direction parallel to the arc-shaped touch panel, B is the distance between the largest protruding portion of the binding area 21 and the effective touch area 10, hereinafter referred to as the hypotenuse frame, and C is the distance between the smallest protruding portion of the binding area 21 and the effective touch area 10, hereinafter referred to as the straight-sided frame. As shown in fig. 1, the in-line parallel arrangement of the binding terminals 01 may make the hypotenuse frame B of the binding area 21 larger, and the hypotenuse frame B directly affects the size of the touch device housing, because the touch device housing needs to cover the binding area 21 so that the binding area 21 is not visible from the outside, and the binding area 21 with the larger hypotenuse frame B will result in the touch device housing having a wider size, which is not beneficial to realizing the narrow frame of the touch device. Therefore, for the arc-shaped touch product, the bevel edge frame B is an important parameter of the whole machine design.
In summary, for the existing arc-shaped touch device and the binding area of the flexible circuit board therein, the touch device, the touch display device and the wearable device in the embodiment of the invention are provided, so as to solve the problem that the binding area of the existing arc-shaped touch device is wider, thereby leading to wider frame of the touch device shell covering the binding area, and being unfavorable for realizing narrow frame of the touch device.
Example 1
Fig. 2 is a schematic diagram of an arc-shaped touch device according to a first embodiment of the present invention, and referring to fig. 2, the arc-shaped touch device includes an arc-shaped binding area 22, where a plurality of binding terminals 02 for binding one end of a flexible circuit board 40 are provided, the other end of the flexible circuit board 40 is used for binding a touch chip, and the plurality of binding terminals 02 are arranged along an arc shape of the arc-shaped binding area 22.
The arc-shaped touch device comprises an effective touch area 10 and an edge area 20, and a binding area 22 of a flexible circuit board 40 for binding a touch chip is located in the edge area 20.
As can be seen by comparing fig. 2 and fig. 1, the hypotenuse frame B ' in fig. 2 is smaller than the hypotenuse frame B in fig. 1, and the hypotenuse frame B ' in fig. 2 is equal to the straight-sided frame C ' in fig. 2.
In the embodiment of the invention, the plurality of binding terminals 02 in the arc binding area 22 can be distributed along the arc of the arc binding area 22, so that the binding terminals 02 do not exceed the edge area 20 of the arc touch device, and correspondingly, the arc binding area 22 provided with the binding terminals 02 does not have a protruding end relative to the edge area 20, thereby shortening the bevel edge frame of the arc binding area 22 for binding the touch chip, and further, the size of the shell of the touch device wrapping the binding area can be correspondingly reduced.
Alternatively, referring to fig. 2, the plurality of binding terminals 02 may be arranged in a fan shape along the arc shape of the arc-shaped binding region 22, that is, each binding terminal 02 may have a certain angle therebetween.
As shown in fig. 2, the extension lines of the binding terminals 02 may intersect at the geometric center point O of the effective touch area 10, but may also intersect at other positions. In addition, it is also possible that the extension lines of a part of the binding terminals 02 intersect at one position, and the extension lines of another part of the binding terminals 02 intersect at another position, so long as it is ensured that a plurality of binding terminals 02 are arranged along the arc shape of the arc-shaped binding region 22 without exceeding the edge region 20, which is not particularly limited in the embodiment of the present invention.
Optionally, fig. 3 is a schematic diagram of another arc-shaped touch device according to the first embodiment of the present invention, referring to fig. 3, the plurality of binding terminals 02 are parallel to each other, and one end of each binding terminal 02 near the edge of the arc-shaped binding region 22 is arranged along the arc shape of the arc-shaped binding region 22. As shown in fig. 3, the extension lines of the plurality of binding terminals 02 are parallel to each other, but the overall profile of the plurality of binding terminals 02 still conforms to the arc shape of the arc-shaped binding region 22.
Alternatively, referring to fig. 2, the flexible circuit board 40 includes a plurality of gold fingers 03 bound to the plurality of binding terminals 02, respectively, and the plurality of gold fingers 03 are identical in arrangement shape to the plurality of binding terminals 02.
The golden fingers 03 on the flexible circuit board 40 for binding the touch chip and the binding terminals 02 need to be bound in a one-to-one correspondence, so that the arrangement shapes of the golden fingers 03 on the flexible circuit board 40 and the binding terminals 02 of the arc binding region 22 can be kept consistent, and good contact between the golden fingers 03 and the binding terminals 02 can be achieved. Of course, in specific application, the arrangement shapes of the golden finger 03 and the binding terminal 02 may also be different, but it is still required to ensure that the golden finger 03 and the binding terminal 02 can achieve binding.
Alternatively, the arc shape of the arc-shaped binding area 22 is a circular arc shape or an elliptical arc shape. In practical applications, if the arc-shaped touch device is a circular touch device, the effective touch area 10 is also circular correspondingly, and the arc of the arc-shaped binding area 22 is also circular correspondingly, as shown in fig. 2 and 3. If the arc-shaped touch device is specifically an elliptical touch device, the effective touch area 10 is also correspondingly elliptical, and the arc of the arc-shaped binding area 22 is correspondingly elliptical arc-shaped, as shown in fig. 4.
In addition, the arrangement scheme of the binding terminals is applicable to the product schemes of the on cell touch device and the external touch device, and the embodiment of the invention is not limited in particular.
The arrangement scheme of the binding terminals is not only suitable for regular round and elliptic touch devices, but also suitable for other irregular arc-shaped touch devices.

In the embodiment of the invention, the plurality of binding terminals in the arc binding area can be distributed along the arc of the arc binding area, so that the binding terminals cannot exceed the edge area of the arc touch device, and correspondingly, the arc binding area provided with the binding terminals also has no protruding end relative to the edge area, thereby reducing the overall size of the arc binding area for binding the touch chip, further correspondingly reducing the size of the shell of the touch device wrapping the binding area, and being beneficial to realizing the narrow frame of the touch device.
