Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those specifically described and will be readily apparent to those of ordinary skill in the art without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.
As shown in the background section, the conventional flexible touch screen has a weak bending resistance.
As shown in fig. 1, fig. 1 is a schematic view illustrating a partial structure of the first touch electrode and the second touch electrode in the conventional flexible touch screen, and it can be seen from fig. 1 that when the flexible touch screen is bent by a dotted line a, a large number of stress points d generated by bending the flexible touch screen in the row direction are more, and the bending resistance is poor; when the flexible touch screen is bent by a dotted line c, more stress points d are generated by bending the flexible touch screen in the row direction, and the bending resistance is poor; and only when the flexible touch screen is bent by taking the dotted line b as a bending axis, the larger stress points d generated by bending in the row direction of the flexible touch screen are fewer, and the bending resistance is better. However, the first touch electrode and the second touch electrode in the conventional flexible touch screen are in a diamond structure, so that the selection range of the bending axis b in the first touch electrode and/or the second touch electrode is relatively small, and the probability that the bending area falls in the area where the bending axis b is located is relatively small, thereby causing the bending resistance of the conventional flexible touch screen to be relatively weak.
As shown in fig. 2, fig. 2 is a schematic diagram of a conventional flexible touch screen in a bent state, specifically, the flexible touch screen is bent with an axis a0 as a folding line to form a first portion a1 and a second portion a2, when performing touch detection, not only a touch operation may affect a capacitance between a first touch electrode and a second touch electrode in the first portion a1 or a capacitance between a first touch electrode and a second touch electrode in the second portion a2, but also the first touch electrode and the second touch electrode in the second portion a2 may affect a capacitance between the first touch electrode and the second touch electrode in the first portion, and similarly, the first touch electrode and the second touch electrode in the first portion a1 may also affect a capacitance between the first touch electrode and the second touch electrode in the second portion a2, that is, an electromagnetic field formed by the touch electrode in the first portion and an electromagnetic field formed by the touch electrode in the second portion may mutually affect a capacitance between the first touch electrode and the touch electrode in the second portion a2 Influence, thereby make when flexible touch-control screen is in crooked or fold condition, the capacitive signal that uses the folding line as the adjacent region of axis influences each other in the flexible touch-control screen, results in flexible touch-control screen is when carrying out touch-control detection through mutual capacitance principle, uses the folding line to reduce as the touch-control detection precision of the adjacent region of axis, the interference killing feature of the folding region of flexible touch-control screen weakens.
In view of this, an embodiment of the present invention provides a flexible touch screen, as shown in fig. 3, the flexible touch screen includes:
the display panel comprises a first display area 100, a bending area 200 and a second display area 300 which are sequentially arranged along a first direction;
a first touch electrode 10, wherein the first touch electrode 10 extends from the first display area 100 to the second display area 300 along the first direction X, and includes a plurality of first sub-electrodes 11 connected to each other;
a second touch electrode 20, where the second touch electrode 20 extends along a second direction Y and includes a plurality of second sub-electrodes 21 connected to each other, the second direction Y intersects the first direction X, and the second touch electrode 20 is not disposed in the bending region 200, that is, the second touch electrode 20 is only located in the first display region 100 and the second display region 300;
a third touch electrode 30, the third touch electrode 30 extending along the second direction Y, and the third touch electrode 30 being disposed in the bending region 200, wherein at least one side of the third touch electrode 30 is parallel to the second direction Y.
It should be noted that, in the embodiment of the present invention, the third touch electrode 30 overlaps with any one of the first touch electrodes 10 in the flexible touch screen, so that when the flexible touch screen is bent with a certain line in the third touch electrode 30 as an axis, the bending axis overlaps with only one of the third touch electrodes 30 in the flexible touch screen, so as to reduce the number of stress points when the flexible touch screen is bent with a certain line in the third touch electrode 30 as an axis.
Optionally, on the basis of the foregoing embodiment, in an embodiment of the present invention, each position of the third touch electrode 30 has the same width along the first direction, specifically, the third touch electrode 30 is rectangular, but the present invention is not limited to this, and in other embodiments of the present invention, the third touch electrode 30 may also be square, or trapezoidal or other patterns, as long as the degree of each position of the third touch electrode 30 along the first direction is greater than a preset value, so that when the flexible touch screen is bent with a certain line in the third touch electrode 30 as an axis, the bending axis only overlaps with one third touch electrode 30 in the flexible touch screen, and only has two intersection points with the edge of the third touch electrode 30.
Therefore, in the flexible touch screen provided by the embodiment of the present invention, at least one side edge of the third touch electrode 30 located in the bending region 200 is parallel to the second direction Y, so that the flexible touch screen is bent along any bending axis of the third touch electrode 30 parallel to the second direction Y, the generated stress points are fewer, the bending region range where fewer stress points are generated in the flexible touch screen is enlarged, and the bending resistance of the flexible touch screen is improved.
