In some embodiments, at least two of the half waves have different wave forms.

In some embodiments, the different wave forms comprise a triangular half wave form and a trapezoidal half wave form; and the base lines are aligned along a direction substantially parallel to the column direction.

Sometimes, due to poor flexibility of indium tin oxide (ITO) as shown in Fig. 14, the touch electrode pattern is prone to rupture nearby a bending line as shown by the dotted line in Fig. 14. When that happens, the flexible touch panel is destroyed.

Therefore, it is a technical problem to be solved to prevent the rupture of the touch electrode pattern from affecting the touch operation performance during use of the foldable type flexible touch panel.

Example implementations of the flexible touch panel and a display device according to embodiments of the present disclosure are described below in detail with reference to figures.

Shapes and sizes of components in the figures do not reflect real scale of the flexible touch panel and are only intended to illustrate the content of the present disclosure.

As shown in FIG. 15 through FIG. 20, a flexible touch panel according to some embodiments of the present disclosure may include: a flexible substrate baseplate 100, a touch electrode layer having a plurality of touch electrode patterns on the flexible substrate baseplate, and the flexible touch electrode pattern 200 disposed on the flexible substrate baseplate 100, and the flexible touch panel has at least one bendable area, and at least one of the touch electrode patterns within the bendable area 300 has a cutoff region to divide one electrode pattern into insulated portions.

The bendable area 300 arranged on the flexible touch panel and having at least one relatively fixed position, where at least part of the flexible touch electrode pattern 200 in the bendable area 300 has a cutoff region A that may divide the electrode pattern into two substantially complementary portions. Each of the touch electrode patterns within the bendable area has the cutoff region to divide the one electrode pattern into the insulated portions.

The bendable area 300 in the touch panel may be bended when needed. When the bendable area 300 is bended, the touch panel may be folded into two or multiple folds from a flat touch panel. Not all areas of the touch panel may be bent. When the touch panel is folded, the bendable area 300 may be bent and the rest of areas of the touch panel may not be bent, and may be the relatively fixed positions. The purpose of the bendable area 300 is for the touch panel to be folded. Sometimes, the bendable area 300 may have a cutoff region that may have a substantially 90%difference from the direction of the folding of the touch panel. For example, in FIG. 19, each bendable area 300 has a cutoff region that has a horizontal direction while the touch panel may be folded vertically. Thus, the flexible touch panel may have one bendable area, the flexible touch panel may be bendable along a first direction, and an extension direction of the bendable area may be along a second direction that is substantially perpendicular to the first direction. The cutoff region may substantially extend along the extension direction of the bendable area. As such, all the touch electrode patterns within the bendable area may have the cutoff region to divide one electrode pattern into two insulated portions, and the two insulated portions may be distributed symmetrically in respect to the cutoff region.

However, as shown in FIG. 16 and FIG. 17, sometimes, even though the direction of the folding is substantially vertical, the bendable area 300 may have the cutoff regions with more than one directions. Such directions may or may not be the same.

Thus, connections of all cutoff regions within the bendable area bendable may be substantially a straight line as a whole. Sometimes, connections of all cutoff regions within the bendable area are substantially a bent line as a whole as shown in FIG. 16 and FIG. 17.

For example, in the embodiments illustrated in FIG. 16 and FIG. 17, the cutoff region A extends along a direction parallel to the substrate baseplate (e.g., in the state of being flat without being bent) . For example, the cutoff region has a width in the direction perpendicular to the extending direction can be designed as small as possible, e.g, less than 10 μm. For example, the width can be 6 μm or 2 μm.

In the flexible touch panel, the flexible touch electrode pattern 200 may be liable for the rupture in the bendable area 300 which is at a relatively fixed position. A transparent electrically conductive material with poor flexibility such as ITO may be selected, for optical performance, as the material for making the flexible touch electrode pattern 200. Therefore, in the bendable area 300 which is liable to rupture, at least part of the flexible touch electrode pattern 200 is directly arranged with the cutoff region A.

However, when at least part of the flexible touch electrode pattern 200 disposed in the bendable area 300 is removed, the location at the cutoff region A may be enabled to release stress when it is bent. Thus, damages caused by the stress generated by the bending to the flexible touch electrode pattern 200 may be avoided in the bendable area 300, and at the same time, the removal of the part of flexible touch electrode pattern in the bendable area does not affect the touch operation performance.

It should be noted that the flexible touch panel according to the embodiment of the present disclosure may be adapted for a flexible display panel having a relatively fixed folding position. Generally, the bendable area 300 is located in the middle of the flexible touch panel, for example, on a central axis. Sometimes, the bendable area 300 may be disposed closely at an edge position of the flexible touch panel in accordance with the requirement of some applications. Also, the number of the bendable areas 300 may be one or more.

The following examples describe the scenarios that the bendable area 300 is disposed in the middle of the flexible touch panel. However, in practice, the bendable area 300 may be in the other areas of the flexible touch panel.

In the flexible touch panel according to the embodiment of the disclosure, at least part of the flexible touch electrode pattern 200 in the bendable area 300 is arranged to contain a cutoff region A. The flexible touch electrode patterns 200 on two sides of the cutoff region A may be independent from each other and may be spaced apart by the cutoff region A.

To ensure normal performance of touch detection, it is possible to respectively arrange a separated signal wiring connected with a touch chip at the flexible touch electrode patterns 200 on two sides of the cutoff region A. The flexible touch electrode patterns 200 on each side of the cutoff region A is connected with the touch chip via a corresponding signal wiring respectively.

When the flexible touch electrode pattern 200 is completely cut off at the bendable area 300 as shown in FIG. 15 through FIG. 18, the flexible touch electrode pattern 200 is divided into two completely independent pattern regions along the location of the cutoff region A. A left pattern and a right pattern as shown in the figures.

Thus, it is possible to respectively use an independent touch chip to control the left pattern and right pattern to execute the touch detection function. The flexible touch panel may be considered as two independent panels. The flexible touch electrode patterns 200 located on two sides of the cutoff region A may be respectively connected with different touch chips through respective signal wirings. Thus, touch electrode patterns located on two sides of the cutoff region may be connected by separated signal wirings and a single touch chip. Also, touch electrode patterns located on two sides of the cutoff region are connected by separated signal wirings and different touch chips.

In a possible implementation, one part of the touch electrode patterns may include touch driving electrodes and another part of the touch electrode patterns may include touch sense electrodes.

In the flexible touch panel according to the embodiment of the disclosure, to make the location of the cutoff region A of the flexible touch electrode pattern 200 in the bendable area 300 invisible as much as possible and to mitigate the impact on display consistency of the flexible touch panel, in one implementation, the location of the cutoff region A of the flexible touch electrode pattern 200 may be as small as possible. Thus, a gap of the cutoff region A should be as narrow as possible, and the pattern at the location of the cutoff region A may be designed as disorderly as possible to make the location not easily be noticed.

In one implementation, in the flexible touch panel according to the embodiment of the disclosure, the flexible touch electrode pattern 200, as shown in FIG. 15 through FIG. 20, generally may include: touch driving electrodes 210 and touch induction electrodes 220. An extension direction of the touch driving electrodes 210 may be a horizontal direction as shown in FIG. 15 through FIG. 20. Correspondingly, an extension direction of the touch induction electrodes 220 may be a vertical direction. Alternatively, the extension direction of the touch driving electrodes 210 may be a vertical direction, and correspondingly, the extension direction of the touch induction electrodes 220 may be a horizontal direction. The extension directions may have many variations. The touch driving electrodes 210 and touch induction electrodes 220 may be generally shaped as a diamond.

As shown in FIG. 15 through FIG. 20, each of the touch driving electrodes 210 comprises a plurality of electrode blocks which are connected in sequence. The arrangement direction of the electrode blocks in each touch driving electrode is the horizontal direction, i.e., it is the extension direction of the touch driving electrode 210. The arrangement direction of the electrode blocks in each touch induction electrode 220 is the vertical direction, i.e., it is the extension direction of the touch induction electrode 220.

In some embodiments, as shown in FIG. 15 through FIG. 20, the electrode blocks in the touch driving electrodes 210 and touch induction electrodes 220 may be shaped as square or circle. In some embodiments, the electrode blocks in the touch driving electrodes 210 and the electrode blocks in the touch induction electrodes 220 are shaped as the same. In some embodiments, shapes of the electrode blocks in the touch driving electrodes 210 and the electrode blocks in the touch induction electrodes 220 are different from each other.

The flexible touch electrode pattern 200, as shown in FIG. 15 through FIG. 20, generally may include: a jumper line 230 that bridges adjacent electrode blocks in the touch driving electrodes 210 or adjacent electrode blocks in the touch induction electrodes 220. For example, as shown in FIG. 15 through FIG. 20, the electrode blocks in each touch driving electrode are connected with the jumper line 230 so as to form the touch driving electrode extending along the horizontal direction. For the electrode blocks in the touch induction electrode, the adjacent electrode blocks can be directly connected with each other or connected with a connection line integrally formed with the electrode blocks. The bendable area may have at least one jumper line, and at least part of the at least one jumper line within the bendable area may be in the cutoff region of the bendable area. In FIG. 15 through FIG. 20, the example is provided to show the jumper line 230 to bridge adjacent electrode blocks of the touch driving electrodes 210. The jumper line may also bridge adjacent touch induction electrodes which is not shown in FIG. 15 through FIG. 20. Thus, a plurality of jumper line with each electrically connecting adjacent touch electrode patterns. For example, the first touch electrode 210 includes a plurality of first touch electrode blocks (the square as illustrated in FIG. 15) arranged in the first direction (e.g., the horizontal direction in FIG. 15) , every two first touch electrode blocks adjacent along the first direction are connected by a first connecting portion. The second touch electrode 220 includes a plurality of second touch electrode blocks (the square as illustrated in FIG. 15) arranged in the second direction (e.g., the vertical direction in FIG. 15) , every two second touch electrode blocks adjacent along the second direction are connected by a second connecting portion. For example, one of the first connecting portion and the second connecting portion is the jumper line as described above, and the other one can be a portion integral with the touch electrode blocks and between adjacent touch electrode blocks. In FIG. 2, as an example, the first connecting portion is the jumper line 230, and the second connecting portion is the portion between adjacent second touch electrode blocks and shielded by the jumper line230.

In the flexible touch panel according to the embodiment of the disclosure, the touch driving electrodes 210 and touch induction electrodes 220 included by the flexible touch electrode pattern 200 generally may use a transparent electrically conductive material such as ITO. The jumper line 230 may use either a metallic material or a transparent electrically conductive material. The present disclosure does not limit the use of materials.

Based on the above flexible touch electrode pattern 200, in the flexible touch panel according to the embodiment of the disclosure, there may be the cutoff region A with different patterns depending on different structures of the flexible touch electrode pattern 200 included in the bendable area 300. Detailed depictions are provided by describing several examples below.

In the flexible touch panel according to the present embodiment, as shown in FIG. 15 through FIG. 17, the touch driving electrodes 210 or touch induction electrodes 220 included in the bendable area 300 have the cutoff region A in the extension direction of the bendable area 300.

For example, in the embodiments illustrated in FIG. 15 and FIG. 17, the cutoff region is located in the touch electrode blocks within the bendable area of the first touch electrodes 210.

In one implementation, the electrodes located in the cutoff region A need to be determined according to whether the flexible touch electrode pattern 200 included at the location of the bendable area 300 is in the touch driving electrodes 210 or touch induction electrodes 220. Each of FIG. 15 through FIG. 17 exemplarily illustrates the bendable area 300 covering the touch driving electrodes 210 as an example. In the extension direction of the bendable area 300, multiple touch driving electrodes 210 in the bendable area 300 contain the cutoff region A.

Specific graphs for performing the cutoff processing may employ multiple manners. For example, performing the cutoff processing may be in a straight line manner as shown in FIG. 15, performing the cutoff processing may be in a bent line manner as shown in FIG. 16 and FIG. 17, or performing the cutoff processing may be in a curved line manner. Performing the cutoff processing may also be in other ways which are not elaborated herein. In another implementation, the cutoff graph resulting from the cutoff processing in the bent line manner may be more disorderly than that resulting from the cutoff processing in the straight line manner and may not be easily noticed. However, the graphs other than the straight line may be more complicated, and may impose certain requirements for the precision of the manufacturing process.

As shown in FIG. 15, the touch driving electrodes 210 or touch induction electrodes 220 included in the bendable area 300 have a straight line cutoff region A in the extension direction of the bendable area 300. As shown in FIG. 16 and FIG. 17, the touch driving electrodes 210 or touch induction electrodes 220 included in the bendable area 300 have a bent line cutoff region A in the extension direction of the bendable area 300. When the cutoff processing is performed in the bent line manner, the touch driving electrodes 210 or touch induction electrodes 220 included in the bendable area 300 may have a serrated bent line cutoff region A as shown in FIG. 16 or a concave and convex bent line cutoff region A as shown in FIG. 17 in the extension direction of the bendable area 300.

In the flexible touch panel according to the present embodiment, when the touch driving electrodes 210 or touch induction electrodes 220 in the bendable area 300 are cut off, it may further perform a hollowing processing at the cutoff location to further release the stress during the bending.

As shown in FIG. 18, the touch driving electrodes 210 or touch induction electrodes 220 having the straight line cutoff region A further have a central hollowed region B including the cutoff region A. A central region of the touch driving electrodes 210 or touch induction electrodes 220 having the cutoff region A is hollowed on the basis of the cutoff region A. Thus, the touch electrode pattern within the bendable area may have the cutoff region with central hollowed portions.

Such hollowed region B and the cutoff region A in the hollowed region B may facilitate the folding of the touch panel. When the foldable area as shown in FIG. 18 is substantially hollowed, the touch panel may be folded along the cutoff region A without much resistance. Because the foldable area is hollowed, the touch panel may be folded repeatedly without wearing out the foldable area.

In one implementation, the shape of the hollow may vary. For example, it may be a shape such as circle, rectangle or polygon. However, a maximum hollowing degree should be a pattern line width that may be ensured by the capacity of the process. The hollowing should ensure integrity of outer contour of the touch driving electrodes 210 or touch induction electrodes 220. Each touch electrode pattern within the bendable area may have the cutoff region with central hollowed portions.

For example, as shown in FIG. 18, the central hollowed regions B of the touch driving electrodes 210 or touch induction electrodes 220 having the straight line cutoff region A are arranged to match the outer contour of the touch driving electrodes 210 or touch induction electrodes 220. The pattern line width of the touch driving electrodes 210 or touch induction electrodes 220 having the central hollowed regions B may be greater than 20μm. Thus, the pattern line width of the outer contour of the touch electrode patterns within the bendable area may be greater than 20μm.

In Example 1 and Example 2, by means of designing the location of the bendable area 300, it may ensure that the touch driving electrodes 210 or the touch induction electrodes 220 having the cutoff region A are distributed symmetrically in respect to the cutoff region A.

In the flexible touch panel according to the present embodiment, as shown in FIG. 19 and FIG. 20, when the bendable area 300 includes the jumper line 230, at least part of the jumper line 230 included in the bendable area 300 may have the cutoff region A. As such, the impact exerted by the stress to the jumper line 230 may be reduced and the rupture of the jumper line 230 which may affect the touch operation performance can be prevented. Thus, each of more than one jumper lines may be a straight line having a cutoff part in the cutoff region. Sometimes, the more than one jumper lines may also be a bent line having a cutoff part in the cutoff region.

In one implementation, it is possible to perform the cutoff processing for all jumper lines 230, or a part of lines 230 included in the bendable area 300 or other variations which are not elaborated herein. For example, as shown in FIG. 19, each of jumper lines 230 that are located on the same straight line may be arranged to have the cutoff region A. Alternatively, as shown in FIG. 20, each of jumper lines 230 that extend in the bent line may be arranged to have the cutoff region A. In both FIG. 19 and FIG. 20, the cutoff region A is illustrated as jumper lines 230 that have dotted lines. The jumper lines 230 having dotted lines are to be moved. In practice, it is possible to remove merely part of jumper lines rather than the whole jumper lines in order to perform the cutoff processing.

It should be noted that in the flexible touch panel according to the embodiment of the present disclosure, the cutoff processing may be performed only for the touch driving electrodes 210 or for touch induction electrodes 220 included in the bendable area 300. Alternatively, the cutoff processing may be performed only for the jumper lines 230 included in the bendable area 300, or simultaneously for the electrode blocks of the touch driving (induction) electrodes 210 (220) and the jumper lines 230 included in the bendable area 300. Other variations may be available and the present disclosure does not elaborate.

In some embodiments, the flexible touch panel includes an effective area provided with the touch electrodes and a periphery area surrounding the effective area. Fig. 21 illustrates a structural schematic view of a flexible display panel according to some embodiments of the present disclosure. For example, as illustrated in FIG. 21, the part of the first touch electrode 210 located at the left side of the cutoff region A is connected to a touch chip 410 through leads at the left side of the effective area, and the part of the first touch electrode 210 located at the right side of the cutoff region A is connected to a touch chip 420 through leads at the right side of the effective area. For the second touch electrodes 220, their extending direction is substantially parallel to the extending direction of the bendable area, and they can be divided as the second touch electrodes 220 at the left side of the cutoff region A and the second touch electrodes 220 at the right side of the cutoff region A. The second touch electrodes 220 at the left side of the cutoff region A can be connected to the touch chip 410, and the second touch electrodes 220 at the right side of the cutoff region A can be connected to the touch chip 420. Therefore, the touch electrode pattern can be divided into two parts at both sides of the cutoff region, which are controlled by two touch chip, respectively. For example, in the case that the flexible touch panel is applied in the bendable display screen, the touch region at one side of the bendable area may correspond to a non-display region when the bendable display screen is bent. In this case, this touch region can be controlled to cease to work so as to avoid the touch detection error caused by the touch floating phenomenon when the non-display region is touched. For example, in this embodiment, the touch electrode 210 extending horizontally is a touch induction electrode and the touch electrode 220 extending vertically is a touch driving electrode.

The above description takes the touch electrode pattern prepared from transparent conductive oxide such as ITO as an example, however, the embodiments of the present disclosure is not limited thereto, and the touch electrode pattern according to the embodiments of the present disclosure can also be a metal mesh electrode pattern or an electrode pattern of any other suitable material. For example, in the touch electrode pattern as illustrated in FIGs. 15 to 20, each square electrode block is replaced with a metal mesh block so as to form the metal mesh touch electrode pattern. For example, the electrode blocks of the first touch electrode and the electrode blocks of the second touch electrode can be metal mesh patterns. The metal mesh electrode blocks are connected by the first connecting portion and the second connecting portion. One of the first connecting portion and the second connecting portion is the jumper line, and the other may be a connecting line integrally formed with the metal mesh electrode blocks. Similarly, in the case of the metal mesh touch electrodes, the cutoff region can exist on the connecting portions or the electrode blocks, or on both the connecting portions and the electrode blocks.

In the case of the metal mesh electrode pattern, the cutoff region is realized by disconnecting the grid lines in a predetermined region. Each electrode block can include a plurality of grids, and the cutoff region can include a plurality of breakpoints in the grid lines defining the grids. As illustrated in FIG. 22, it illustrates a partial plan view of a metal mesh electrode block. The metal mesh electrode block includes a plurality of grids 510 connected to each other in a net or mesh shape. In the example illustrated in FIG. 22, each grid is approximately hexagonal in shape, however, the embodiments according to the present disclosure are not limited thereto, and the shape of the grids may be quadrangle or other polygon or irregular shape. The grid lines defining each grid are formed by metal lines, which may be silver nanowires or other suitable metal lines, for example. In order to realize the cutoff region of the metal mesh electrode block, fractures can be formed at the predetermined positions of some grid lines.

In the embodiments illustrated with reference to FIG. 16 and FIG. 17, the cutoff region of the electrode block may be in the form of a broken line. In the case of a metal mesh electrode pattern, for example, as illustrated in FIG. 22, along a broken line line 600 extending substantially in the horizontal direction in the figure, the grid lines are disconnected at the intersection positions of the broken line 600 and the grid lines defining the grids 510 to form the breakpoints. For example, in the case of such a cutoff region, the connecting line between the breakpoints is also a broken line, that is, it is not on the same straight line. For example, the broken line formed by the connecting line between breakpoints includes a plurality of straight line segments connected end to end, and the number of grids that each straight line segment passes through is not more than 5. That is to say, the breakpoints forming the cutoff region are not located on the same straight line. The maximum distance spanned by adjacent breakpoints on the same straight line does not exceed 5 grids. In this way, the visualization phenomenon of the cutoff region caused by the diffraction enhancement at the cutoff region can be weakened or avoided. For example, in each first touch electrode block, the breakpoints are not at the same straight line.

In addition, as described above, in order to avoid the visualization of the cutoff region, the cutoff region can be made as small as possible. In the case of the metal mesh electrode pattern, since its disconnection position is realized by each breakpoint on the grid line, the breaking distance (distance between opposite ends of disconnected grid line) of the breakpoint of the grid line can be very small, for example, it can be less than 10 μm. In some examples, the breaking distance may be less than or equal to 6 μm or 2 μm.

In some embodiments as mentioned above, the cutoff region is located around the bending axis and runs through the whole touch electrode pattern along the bending axis. However, the embodiments according to the present disclosure are not limited thereto, for example, the cutoff region can be provided at only partial positions in the direction along the bending axis; or, although the cutoff region is in the bendable area, it can deviate from the bending axis; alternatively, the cutoff region can be located at any other position within the bendable area. For example, the bending axis can be the center line of the strip-shaped bendable area.

The flexible touch structure described above can be a flexible touch panel alone or a flexible touch display panel bonded with a display structure, and the combination mode of the flexible touch structure and the display structure is not particularly limited. For example, it can be an out-cell touch display device in which a flexible touch panel is bonded with a display panel, or an on-cell or in-cell touch display device in which the touch structure is combined in the display panel. For example, in the case of an out-cell touch display device, the flexible touch panel and the display panel may be bonded with each other. In case of the on-cell and in-cell touch display device, the flexible substrate baseplate of the flexible touch panel can be one substrate in the display panel. For example, the above touch control structure can be integrated on the OLED display substrate, and it can be formed on the packaging layer of the OLED display substrate.

Based on the same disclosed concept, embodiments of the present disclosure may further provide a display device. The display device may include the flexible touch panel described above according to embodiments of the present disclosure. The display device may be any product or component having the display function such as a mobile phone, a tablet computer, a TV set, a display, a notebook computer, a digital photo frame or a navigator.

Thus, at least part of the flexible touch electrode pattern which should have been disposed in the bendable area is removed, thereby enabling these cutoff locations to release stress when the bendable area is bent.
