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.
As shown in fig. 1, fig. 1 is a schematic structural diagram of a conventional electronic device in the prior art, in which a flexible touch display panel 11 is disposed on a surface of a body 12. The flexible touch display panel 11 can cover the side area 13 of the body 12, so that the side area 13 can display images, the display area of the electronic device is increased, and more image information can be displayed.
However, since the flexible touch display panel 11 is an integrated touch display, the electronic device shown in fig. 1 inevitably touches the side area 13 during the holding process. At this time, if the electronic device is in a touch working state, the holding action is recognized as a touch operation, which results in misoperation.
In order to solve the above problem, an embodiment of the present invention provides a touch display panel, including:
a first region, a second region and a third region arranged in sequence in a first direction;
the first region and the third region are not coplanar with the second region;
the first area and the third area are at least provided with preset partial areas which are only used for image display in the first working mode, and touch detection and image display are simultaneously carried out in the second working mode.
In the touch display panel, the first area and the third area are at least provided with preset partial areas which are only used for image display in the first working mode, and touch detection and image display are simultaneously carried out in the second working mode. Thus, when the display panel works, if the preset partial area is set in the first working mode, the preset partial area is only used for image display and is not used for touch detection, at this time, a user holds or touches the preset partial area, and touch operation of the electronic equipment cannot be executed. Therefore, the touch display panel can avoid the problem that the user is identified as touch operation when holding the side area, and avoid misoperation caused by the problem.

In this way, when the first area 21 and the third area 23 perform touch detection, and the first area 21 and the third area 23 perform touch detection, the same accuracy may be adopted, so that the first area 21 and the third area 23 perform touch detection by using the same touch detection algorithm.
In the embodiment shown in fig. 2 and 3, the second region 22 is a plane, that is, the outer surface of the second region 22 is a plane, the first direction X is parallel to the second region 22 and perpendicular to the first common boundary L1 of the first region 21 and the second region 22 and the second common boundary L2 of the second region 22 and the third region 23, and the first region 21 and the third region 23 are symmetrically disposed at two sides of the second region 22.

The first touch film region 51 has at least a portion insulated from the second touch film region 52, and the third touch film region 53 has at least a portion insulated from the second touch film region 52, so that the first region 21 and the third region 23 each have at least a predetermined partial region for only image display in the first operation mode, and touch detection and image display are simultaneously performed in the second operation mode. The touch film layer 25 corresponding to the predetermined partial area in the first area 21 and the third area 23 is insulated from the touch film layer 25 corresponding to the second area 22, so that the predetermined partial area in the first area 21 and the third area 23 and the second area can be independently used for touch detection.
In the first operating mode and the second operating mode, the second region 22 performs touch detection and image display simultaneously. That is, in the first operation mode and the second operation mode, the touch detection may be performed when the second region 22 displays an image.
In the manner shown in fig. 5, the first touch pad region 51 is located entirely within the first region 21 and is insulated from the second touch pad region 52. The second touch pad region 52 is located entirely within the second region 22.

The first sub-area 31 and the fourth sub-area 34 are not provided with touch control film layers.
It should be noted that the mirror symmetry between the first area 21 and the third area 23 refers to the shapes of the two areas and the stacking sequence of the functional layers, so that the two areas have the same touch detection accuracy, and the tracks of the touch film layer 25 corresponding to the two areas are not included. That is, the trace of the portion of the touch film layer area 25 corresponding to the first area 21 may be asymmetric to the trace of the portion of the touch film layer area 25 corresponding to the third area 23, or two portions of the traces may be provided symmetrically.
In the embodiment shown in fig. 6, the first touch-control film region 51 does not perform touch detection in the first operation mode, and only image display is performed on the second sub-region 32; the third touch pad area 53 does not perform touch detection in the first operation mode, and only the image display is performed in the third sub-area 33.
