It should be noted that, when both the first bending portion 210 and the second bending portion 220 have no touch function, the first bending portion 210 only includes the fourth edge region 300/4, and the second bending portion 220 only includes the complete first edge region 300/1 or the partial first edge region 300/1. In addition, when the first bending portion 210 and the second bending portion 220 both have the touch function, the first bending portion 210 includes the fourth edge region 300/4 and the partial touch region 200, and the second bending portion 220 includes the complete first edge region 300/1 or the partial first edge region 300/1 and the partial touch region 200. Notably, when the second bend 220 includes the complete first edge region 300/1, the bend 240 includes only the binding region 100; when the second bend 220 includes a portion of the first edge region 300/1, the bent portion 240 includes the binding region 100 and another portion of the first edge region 300/1. Figure 3 illustrates the case where the first bend 210 includes only the fourth edge region 300/4, the second bend 220 includes only the complete first edge region 300/1, and the bend 240 includes only the bonded region 100.
It should be noted that, the first bending portion 210 and the second bending portion 220 are disposed to narrow the widths of the two frames of the flexible touch panel corresponding to the first edge region 300/1 and the fourth edge region 300/4 in a top view, which is beneficial to narrow the frames of the flexible touch panel.
Referring to fig. 1 and 2, the touch electrodes 120 include a plurality of first touch electrodes 121 disposed in parallel and a plurality of second touch electrodes 122 disposed in parallel, and the extending directions of the first touch electrodes 121 and the second touch electrodes 122 are perpendicular.
With reference to fig. 1, the edge region 300 further includes a second edge region 300/2 and a third edge region 300/3 respectively connected to two ends of the first edge region 300/1, the second edge region 300/2 and the third edge region 300/3 are disposed opposite to each other, the first touch electrode 121 extends along the second edge region 300/2 in a direction toward the third edge region 300/3, a portion of the touch trace 140 electrically connected to the first touch electrode 121 may extend from the touch region 200 to the bonding region 100 through the second edge region 300/2 and the first edge region 300/1, and another portion of the touch trace extends from the touch region 200 to the bonding region 100 through the third edge region 300/3 and the first edge region 300/1; the touch trace 140 electrically connected to the second touch electrode 122 extends from the touch area 200 to the bonding area 100 through the first edge area 300/1.
It should be noted that, in the above-mentioned arrangement manner, on one hand, the touch traces 140 electrically connected to the first touch electrodes 121 can extend to the corresponding pads 130 in a shorter path, and on the other hand, since the number of the touch traces 140 can influence the width of the edge region 300 where the touch traces are located to some extent, the arrangement manner can also avoid that the difference between the widths of the second edge region 300/2 and the third edge region 300/3 is too large. It can be understood that the closer the number of the touch traces 140 routed through the second edge region 300/2 and the number of the touch traces 140 routed through the third edge region 300/3 are, the smaller the difference between the widths of the second edge region 300/2 and the third edge region 300/3 is, and therefore, for example, when the number of the first touch electrodes 121 is even, half of the touch traces 140 electrically connected to the first touch electrodes 121 may be configured to extend from the touch region 200 to the bonding region 100 through the second edge region 300/2 and the first edge region 300/1, and the other half of the touch traces 140 may extend from the touch region 200 to the bonding region 100 through the third edge region 300/3 and the first edge region 300/1.
For example, the first touch electrode 121 may be a touch driving electrode, and the second touch electrode 122 may be a touch detecting electrode; alternatively, the first touch electrode 121 may be a touch detection electrode, and the second touch electrode 122 may be a touch driving electrode.
Fig. 4 is a schematic top view structure diagram of another flexible touch panel provided in the embodiment of the present invention before being bent. The structure of the flexible touch panel shown in fig. 4 is similar to that of the flexible touch panel shown in fig. 1, except that the touch electrode 120 in fig. 4 is a self-capacitance touch electrode. Referring to fig. 4, the touch traces 140 electrically connected to the respective capacitive touch electrodes extend from the touch area 200 to the bonding area 100 through the first edge area 300/1.
It should be noted that, referring to fig. 1 and fig. 4, no touch trace 140 is disposed in the fourth edge region 300/4 of the corresponding flexible touch panel, which may cause the width of the first edge region 300/1 to be larger than the width of the fourth edge region 300/4, in both the mutual capacitance touch manner and the self-capacitance touch manner, and at this time, the above-mentioned manner of bending part of the first edge region 300/1 together with the bonding region 100 to the side of the flexible substrate 110 away from the touch electrode 120 can be adopted for improvement.
Fig. 5 is a schematic top view of a touch display device according to an embodiment of the invention. Fig. 6 is a schematic cross-sectional view along the dashed line CD in fig. 5. It should be noted that, in order to simplify the structure of the drawing, the touch electrode 120 is not shown in fig. 6. As shown in fig. 5 and 6, the touch display device includes a flexible touch panel 20, a display panel 30, and a cover 10 according to any embodiment of the invention. As shown in fig. 6, the flexible touch panel 20 is located on a side of the light emitting surface of the display panel 30, the cover 10 is located on a side of the touch panel away from the display panel 30, and the binding region 100 of the flexible touch panel 20 is located on a side of the display panel 30 away from the cover 10. As shown in fig. 5, the display panel 30 includes a terminal area 400 provided with a display driver chip 401, and the terminal area 400 and the first edge area 300/1 of the flexible touch panel 20 are located on different sides of the touch area 200.
It should be noted that, referring to fig. 1 and the related description, the bonding area 100 and the first edge area 300/1 of the flexible touch panel 20 are located on the same side of the touch area 200, and therefore the terminal area 400 of the display panel 30 and the bonding area 100 of the flexible touch panel 20 are located on different sides of the touch area 200, it is understood that the terminal area 400 of the display panel 30 may be located on the same side of the touch area 200 as the second edge area 300/2, the third edge area 300/3 or the fourth edge area 300/4 of the flexible touch panel 20. The arrangement is such that the terminal area 400 of the display panel 30 does not overlap with the bonding area 100 of the flexible touch panel 20 in the lamination direction of the display panel 30 and the flexible touch panel 20. Based on the flexible technology, the terminal area 400 of the display panel 30 can also be bent to the side of the display panel 30 departing from the cover plate 10, the terminal area 400 of the display panel 30 is not overlapped with the binding area 100 of the flexible touch panel 20, so that the bending positions of the display panel 30 and the flexible touch panel 20 are different, and the bending parts of the display panel 30 and the flexible touch panel 20 are not in contact with each other, thereby avoiding the damage of the bending parts of the flexible touch panel 20 to the structure of the bending parts of the display panel 30.
Optionally, with reference to fig. 5, if the edge region 300 further includes a second edge region 300/2 and a third edge region 300/3 connected to two ends of the first edge region 300/1, respectively, the second edge region 300/2 and the third edge region 300/3 are disposed oppositely, and the terminal region 400 of the display panel 30 and the second edge region 300/2 or the third edge region 300/3 are located on the same side of the touch region 200.
It should be noted that, the above-mentioned setting manner is to make the terminal area 400 of the display panel 30 and the binding area 100 of the flexible touch display panel 30 located at the adjacent side of the touch area 200 of the flexible touch panel 20. In the present embodiment, the above setting manner enables the bending portion of the flexible touch panel 20 to be located at the bending edge position of the touch display device in the prior art, so that the touch display device with the curved edge design does not need to specially bend the edge of the flexible touch panel.
For example, if the edge region 300 further includes a second edge region 300/2 and a third edge region 300/3 connected to two ends of the first edge region 300/1, respectively, the second edge region 300/2 and the third edge region 300/3 are disposed opposite to each other, the flexible touch panel 20 includes a first bending portion 210, a second bending portion 220, an intermediate plane portion 230, and a bending portion 240, the first bending portion 210 and the second bending portion 220 are located on two opposite sides of the intermediate plane portion 230, the bending portion 240 is connected to the second bending portion 220 and located on a side of the second bending portion 220 away from the intermediate plane portion 230, the bending portion 240 is located on a side of the flexible substrate 110 away from the touch electrodes 120 after being bent, the first bending portion 210 at least includes the second edge region 300/2, the second bending portion 220 at least includes a part of the first edge region 300/1, the bending portion 240 at least includes the binding region 100, and the cover panel 10 includes a first bending edge 101 and a second bending edge 102 that are oppositely disposed, the first bending edge 101 overlaps and has the same bending curvature as the first bending portion 210 of the flexible touch panel 20 in the stacking direction Y of the flexible touch panel 20 and the display panel 30, and the second bending edge 102 overlaps and has the same bending curvature as the second bending portion 220 of the flexible touch panel 20 in the stacking direction Y of the flexible touch panel 20 and the display panel 30.
It should be noted that, as shown in fig. 6, the cover plate 10 further includes a middle portion 103 having both ends connected to the first curved edge 101 and the second curved edge 102, respectively. Such an arrangement can narrow the width of the two frames of the touch display device corresponding to the first edge region 300/1 and the fourth edge region 300/4 of the flexible touch panel 20 in a plan view, which is beneficial to the narrow frames of the touch display panel 30.
For example, the touch display device may further include a touch driving chip, where the touch driving chip and the display driving chip 401 are located on the same flexible printed circuit board.
In fig. 5, the display driver chip 401 is disposed on the substrate of the display panel 30, but in addition to this arrangement, the display driver chip 401 may be disposed on a flexible printed wiring board, and the pad 130 disposed on the substrate of the display panel 30 correspondingly is electrically connected to the flexible printed wiring board. For the latter setting mode, after the display driving chip 401 is attached, the flexible printed circuit board where the display driving chip 401 is located may be partially bent to the side of the display panel 30 departing from the cover plate 10, and the binding region 100 of the flexible touch panel 20 is located at the side of the flexible substrate 110 departing from the touch electrode 120, so that the flexible printed circuit board where the display driving chip 401 is located may extend to the position of the pad 130 in the binding region 100 of the flexible touch panel 20, and then the touch driving chip is also set on the flexible printed circuit board through a reasonable circuit design.
It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious modifications, rearrangements, combinations and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail by the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the spirit of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
