All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.

In addition, the three-dimensional dimensions of length, width and height should be included in the actual fabrication.
Fig. 1 is a schematic top view of a touch display panel according to an embodiment of the present invention. As shown in fig. 1, the touch display panel 10 includes a display area 100 and an optoelectronic device reserved area 200, and a boundary between the display area 100 and the optoelectronic device reserved area 200 is a first boundary 300.
Fig. 2 is a schematic sectional view along a broken line AB in fig. 1. As shown in fig. 2, the touch display panel 10 further includes a display substrate 410 and a touch substrate 420, and the touch substrate 420 is located on the light-emitting side of the display substrate 410. The display substrate 410 includes a plurality of organic light emitting units 412, and the plurality of organic light emitting units 412 are disposed in the display area 100. The touch substrate 420 includes a first substrate 421 and a touch layer 422 on the first substrate 421, and the touch layer 422 includes at least one touch electrode layer. The vertical projection of the touch layer 422 on the display substrate 410 covers the vertical projection of the first boundary 300 on the display substrate 410.
It is noted that the first boundary 300 has a linear structure, and the cross-sectional structure along the dotted line AB is two points shown in fig. 2.
It should be noted that the reserved optoelectronic element area 200 is a light-permeable area, and no functional film layer having an obvious blocking effect on light is disposed in the light-permeable area, so that the optoelectronic element disposed on the side of the display substrate 410 away from the touch substrate 420 in the reserved optoelectronic element area 200 can receive sufficient light, and thus the optoelectronic element can work normally. It is understood that the reserved optoelectronic device area 200 is not used for displaying an image because the organic light emitting unit 412 is not disposed in the reserved optoelectronic device area 200.
It should be further noted that, in the present embodiment, the structure of the touch layer 422 is not specifically limited, the number of the touch electrode layers in the touch layer 422 may be 1 or more, for the latter case, the touch layer 422 may further include a plurality of insulating layers disposed between adjacent touch electrode layers, the number, shape and arrangement of the touch electrodes in the touch electrode layers may be reasonably set according to actual needs, and all the structures of the touch layer 422 capable of realizing a touch function are within the protection range of the present embodiment.
In addition, in the stacking direction of the display substrate 410 and the touch substrate 420, the touch layer 422 covers the first boundary 300, so that the touch layer 422 includes a first sub-portion located in the display area 100 and a second sub-portion located in the reserved optoelectronic device area 200, the shape and the size of the second sub-portion are not particularly limited in this embodiment, and any technical solution that can realize that the touch layer 422 covers the first boundary 300 is within the protection scope of this embodiment.
The touch display panel 10 provided by this embodiment includes a display area 100 and a reserved optoelectronic device area 200, a boundary between the display area 100 and the reserved optoelectronic device area 200 is a first boundary 300, the touch display panel 10 further includes a display substrate 410 and a touch substrate 420, the touch substrate 420 is located on a light-emitting side of the display substrate 410, the display substrate 410 includes a plurality of organic light-emitting units 412, the plurality of organic light-emitting units 412 are disposed in the display area 100, the touch substrate 420 includes a first substrate 421 and a touch layer 422 located on the first substrate 421, the touch layer 422 includes at least one touch electrode layer, a vertical projection of the touch layer 422 on the display substrate 410 covers a vertical projection of the first boundary 300 on the display substrate 410, so that an edge of the touch electrode layer generated by cutting does not appear at the position of the first boundary 300, the touch electrode layer near the first boundary 300 has good touch performance, a touch operation of a user in an area near the first boundary 300 in the display area 100 can be effectively identified and responded, and thus the overall touch performance of the touch display device is improved.
With continued reference to fig. 2, within the reserved optoelectronic device area 200, the vertical projection of the touch layer 422 on the display substrate 410 coincides with the vertical projection of the reserved optoelectronic device area 200 on the display substrate 410.
It should be noted that, with such an arrangement, the touch layer 422 is fully distributed in the reserved optoelectronic device area 200, and the touch layer 422 in the display area 100 and the reserved optoelectronic device area 200 is a continuous integral film structure, so that the touch layer 422 in the reserved optoelectronic device area 200 does not need to be cut, which is beneficial to simplifying the manufacturing process of the touch display panel 10.
Fig. 3 is a schematic top view of another touch display panel according to an embodiment of the present invention. Fig. 4 is a schematic cross-sectional view along the dashed line CD in fig. 3. As shown in fig. 3, the touch layer (not shown) includes a first hollow structure 500, and as shown in fig. 4, a vertical projection of the first hollow structure 500 on the display substrate 410 is within a vertical projection of the reserved optoelectronic device area 200 on the display substrate 410, and the vertical projection of the first hollow structure 500 on the display substrate 410 is not connected to a vertical projection of the first boundary 300 on the display substrate 410.
It should be noted that, on one hand, the arrangement is such that in the stacking direction of the display substrate 410 and the touch substrate 420, the touch layer 422 can cover the first boundary 300, so that the edge of the touch electrode layer generated by cutting does not appear at the position of the first boundary 300, and it is ensured that the touch electrode layer near the first boundary 300 has good touch performance, and the touch operation of the user in the area close to the first boundary 300 in the display area 100 can be effectively recognized and responded, thereby improving the overall touch performance of the touch display device. On the other hand, the touch layer 422 in the middle area of the reserved optical electronic element area 200 is removed, and the area has no touch function, so that the occurrence probability of the false touch phenomenon in the reserved optical element area 200 is effectively reduced. In addition, the touch layer 422 is a light-permeable film layer, but still has a certain blocking effect on light, so that the removal of the touch layer 422 in the middle area of the reserved area 200 of the optoelectronic device can achieve the beneficial effect of increasing the light transmittance of the reserved area 200 of the optoelectronic device.
Optionally, with continuing reference to fig. 3, the shape of the outer edge of the vertical projection of the first hollow-out structure 500 on the display substrate is the same as the shape of the first boundary 300, and the distance k between the outer edge and the first boundary 300 is a certain value.
It should be noted that, with such a configuration, the minimum distances from each point on the edge of the touch layer generated by cutting in the reserved area 200 of the optoelectronic device to the first boundary 300 are all equal, and the touch performance in the area near the first boundary 300 in the display area 100 is the same, which improves the uniformity of the touch performance in the area.
Illustratively, the fixed value may range from greater than or equal to 0.5 to less than or equal to 1mm.
It should be noted that too small a value of the fixed value may still cause the touch layer edge generated by cutting in the optical element reserved area 200 to affect the touch performance near the first boundary 300 in the display area 100, and too large a value of the fixed value may cause the size of the touch layer that needs to be cut in the optical electronic element reserved area 200 to be smaller, which increases the difficulty of cutting.
With continued reference to fig. 3, the touch display panel 10 further includes a non-display area 600, and the non-display area 600 is disposed around the display area 100 and the reserved optoelectronic device area 200. Fig. 5 is a schematic view of another cross-sectional structure along the dashed line CD in fig. 3. As shown in fig. 5, the display substrate 410 includes a second substrate 700, and a plurality of light-non-transmissive layers 720 and a plurality of light-transmissive layers 710 formed on the second substrate 700, wherein the light-non-transmissive layers 720 are disposed in the display region 100 and the non-display region 600. At least one of the light-transmissive layers 710 includes a second hollow structure 800, and a vertical projection of the second hollow structure 800 on the first substrate 421 falls within a vertical projection of the reserved optical electronic element area 200 on the first substrate 421.
Alternatively, fig. 6 is a schematic view of another cross-sectional structure along the dashed line CD in fig. 3. The touch display panel 10 shown in fig. 6 has a structure similar to that of the touch display panel 10 shown in fig. 5, except that the second substrate 700 and the plurality of light-transmissive layers 710 in fig. 6 each include a third hollow structure 900, and a vertical projection of the third hollow structure 900 on the first substrate 421 coincides with a vertical projection of the reserved optical element area 200 on the first substrate 421.
Illustratively, referring to fig. 5 and 6, the plurality of light-transmissive layers 710 includes a buffer layer 711, a gate insulating layer 712, an interlayer insulating layer 713, a passivation layer 714, a pixel defining layer 715, a second electrode layer 716, and an encapsulation layer 717, and the light-non-transmissive layer 720 includes an active layer 721, a gate metal layer 722, a source-drain metal layer 723, a first electrode layer 724, and a light-emitting functional layer 725. The pixel defining layer 715 defines a plurality of organic light emitting units 412, each organic light emitting unit 412 includes a first electrode, a light emitting material layer, and a second electrode sequentially disposed along the light emitting direction of the touch display panel 10, the film layer of the first electrode is a first electrode layer 724, and the film layer where the second electrode is located is a second electrode layer 716. The non-light-transmissive layer 720 in the non-display region 600 is used to form devices or circuits in the driving circuit. Fig. 5 only illustrates that the pixel defining layer 715, the second electrode layer 716, and the packaging layer 717 include the second hollow structure 800, and the positions and sizes of the second hollow structures 800 in the film layers are the same, but not limited thereto, and the scheme that one or more of the transparent layers 710 include the second hollow structure 800 is within the protection scope of the present embodiment. In addition, the size of the second hollow structure 800 is not specifically limited in this embodiment, as long as the second hollow structure 800 is in the reserved area 200 of the optoelectronic device.
It should be noted that, each functional film layer in the display substrate 410 is formed on the second substrate 700, and the second substrate 700 is a support of the functional film layer, so that, in the case of removing the second substrate 700 in the reserved optoelectronic device area 200 in fig. 6, other film layers in the display substrate 410 in the reserved optoelectronic device area 200 need to be removed at the same time. It can be understood that, at this time, the optical electronic element may be disposed in the groove structure formed by the plurality of third hollow structures 900 in the reserved optical electronic element area 200, so that the distance between the optical electronic element and the display surface of the touch display panel 10 is closer, and light incident from the outside is more easily received.
The touch display panel 10 shown in fig. 5 and 6 is arranged in a manner that the total thickness of the light-permeable layer 710 in at least a part of the reserved area 200 of the optical electronic element can be reduced, so that the blocking of the light-permeable layer 710 to the light incident in the reserved area 200 of the optical electronic element can be reduced, which is beneficial to the improvement of the light transmittance in the reserved area 200 of the optical electronic element, and ensures that the optical electronic element can receive more light to realize better performance.
Illustratively, fig. 7 is a schematic view of a further cross-sectional configuration along the dashed line CD in fig. 3. The structure of the touch display panel 10 shown in fig. 7 is similar to that of the touch display panel 10 shown in fig. 5, except that the vertical projection of the second hollow structure 800 on the first substrate 421 coincides with the vertical projection of the reserved optoelectronic device area 200 on the first substrate 421.
It should be noted that, the arrangement is such that the light-permeable layer 710 with the second hollow structure 800 does not include the portion arranged in the reserved area 200 of the optoelectronic device, and further, the light-permeable layer 710 does not produce any reduction effect on the light transmittance in the reserved area 200 of the optoelectronic device, thereby increasing the light transmittance of the reserved area 200 of the optoelectronic device to the maximum extent.
Illustratively, with continued reference to FIG. 3, the first boundary 300 may be circular in shape. In other embodiments of this embodiment, the first boundary 300 may also have other shapes, such as a U-shape, as shown in fig. 8.
It should be noted that the shape of the conventional camera is circular or rectangular, and the shape of the first boundary 300 is circular or U-shaped, so that the shape of the reserved optical electronic element area 200 is circular or rectangular, and then the shape of the reserved optical element area 200 is the same as that of the camera, thereby avoiding the occurrence of the situation that part of the reserved optical element area 200 is not effectively utilized due to different shapes, which is beneficial to reducing the area of the reserved optical electronic element area 200, and further increasing the screen occupation ratio of the touch display panel 10.
Fig. 9 is a schematic top view of a touch substrate according to an embodiment of the invention. Fig. 10 is a schematic sectional view along a broken line EF in fig. 9. As shown in fig. 9 and 10, the touch substrate 420 includes a first substrate 421 and a touch layer 422 formed on the first substrate 421, and the touch layer 422 includes a touch electrode layer including a plurality of self-capacitance touch electrodes 431.
It should be noted that, due to such an arrangement, the touch layer 422 is a self-capacitance touch structure, and includes only one self-capacitance touch electrode layer, so that the overall thickness of the touch layer is relatively small, which is beneficial to thinning the touch display panel.
It should be further noted that the principle of the self-capacitance touch structure for realizing touch detection is as follows: the capacitance touch electrode 431 and the ground form a capacitor, when a finger touches the touch display panel, the capacitance of the finger is superposed on the capacitance inside the touch display panel, so that the capacitance is increased, and the touch position of the finger can be determined according to the capacitance signal.
Fig. 11 is a schematic top view of another touch substrate according to an embodiment of the invention. Fig. 12 is a schematic sectional view taken along the dashed line GH in fig. 11. As shown in fig. 11 and 12, the touch layer 420 includes a first touch electrode layer 441 and a second touch electrode layer 442 which are insulated from each other, the first touch electrode layer 441 includes a plurality of touch driving electrodes 433, the second touch electrode layer 442 includes a plurality of touch sensing electrodes 432, and the extending directions of the touch driving electrodes 433 and the touch sensing electrodes 432 intersect.
It should be noted that, by such an arrangement, the touch layer 422 is a mutual capacitance touch structure, which has an advantage that the mutual capacitance touch structure can accurately detect multi-point touch, thereby facilitating the improvement of touch performance of the touch display panel.
It should be further noted that the principle of implementing touch detection by the mutual capacitance touch structure is as follows: the intersection area of the touch driving electrode 433 and the touch detection electrode 432 forms a capacitor, when a finger touches the touch display panel, the capacitance of the finger affects the coupling between the touch driving electrode 433 and the touch detection electrode 432 near a touch point, so that the capacitance between the touch driving electrode 433 and the touch detection electrode 432 is changed, and the touch position of the finger is determined according to a capacitance signal.
Fig. 13 is a schematic structural diagram of a touch display device according to an embodiment of the present invention. As shown in fig. 13, the touch display device 20 includes the touch display panel 10 and the optical electronic element 30 according to any embodiment of the invention, and the optical electronic element 30 is disposed in the reserved optical electronic element area 200. Since the touch display device 20 provided by the present application includes the touch display panel 10 according to any embodiment of the present invention, the same or corresponding beneficial effects of the touch display panel 10 included therein are achieved, and details are not repeated herein.
Illustratively, the optoelectronic element 30 may include one or more of a camera module, a light sensor, and an ultrasonic distance sensor.
