[0047] The following further elaborates on the present invention in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for ease of description, only the parts related to the present invention are shown in the drawings rather than all the structures.

[0048] Based on the above technical problems, the following solutions are proposed in this embodiment:

[0049] Figure 1 is a schematic structural diagram of a touch display panel provided by an embodiment of the present invention. Refer to Figure 1 , the touch display panel 100 provided by the embodiment of the present invention includes a display area 10 and at least a part of a non-display area 20 surrounding the display area 10; at least one horizontal electrode T extending in a first direction N1 and at least one vertical electrode P extending in a second direction N2 are provided in the display area 10, and the first direction N1 and the second direction N2 intersect; at least one horizontal electrode T includes at least two first disconnection parts D1 arranged at intervals, and a space between adjacent first disconnection parts D1 is for light to pass through; and / or, at least one vertical electrode P includes at least two second disconnection parts D2 arranged at intervals, and a space between adjacent second disconnection parts D2 is for light to pass through.

[0050] Specifically, the display area 10 is used for displaying a picture. Pixels 2 are arranged in the display area 10, and the pixels 2 are used for displaying a picture according to a driving signal. The pixels 2 may include sub-pixels 21 of at least three light-emitting colors. The sub-pixels 21 may include a red sub-pixel R, a blue sub-pixel B, and a green sub-pixel G. The horizontal electrode T and the vertical electrode P are arranged in the display area 10, and the display area 10 is used for touch operations. The touch display panel 100 includes a pixel opening for arranging the pixels 2.

[0051] Pixels 2 are not arranged in the non-display area 20. A pixel driving circuit, signal traces, a bonding driving chip, etc. may be arranged in the non-display area 20. A touch driving circuit for the horizontal electrode T and the vertical electrode P may also be arranged in the non-display area 20.

[0052] The first direction N1 may extend along the row direction of the pixels 2, or the first direction N1 may extend along the column direction of the pixels 2. Or, the first direction N1 may be a direction intersecting with the row direction of the pixels 2. Or, the first direction N1 may be a direction intersecting with the column direction of the pixels 2. Or, the first direction N1 may be a direction intersecting with both the row direction and the column direction of the pixels 2, and no limitation is made here.

[0053] The horizontal electrode T and the vertical electrode P may be strip-shaped, may be straight lines, curves, or broken lines, and no limitation is made here. The horizontal electrode T and the vertical electrode P may have a certain width. By adjusting the widths of the horizontal electrode T and the vertical electrode P, the touch area of the touch display panel 100 can be adjusted.

[0054] When the first disconnection part D1 is arranged on the horizontal electrode T, the first disconnection part D1 disconnects the horizontal electrode T. The first disconnection part D1 is arranged in a floating state. A gap is formed between adjacent first disconnection parts D1. This gap is used for light to pass through, increasing the light-transmitting gap on the horizontal electrode T. The horizontal electrode T extending along the first direction N1 includes the first disconnection parts D1 arranged at intervals, so that the light-transmitting area of the horizontal electrode T is increased. Since the first disconnection parts D1 arranged at intervals disconnect the horizontal electrode T, a horizontal electrode T including the first disconnection parts D1 arranged at intervals is composed of at least two electrode segments. The light transmittance between the electrode segments is not blocked by the horizontal electrode T at all, effectively increasing the light-transmitting area of the touch display panel 100.

[0055] When the second disconnection part D2 is arranged on the vertical electrode P, the second disconnection part D2 disconnects the vertical electrode P. The second disconnection part D2 is arranged in a floating state. A gap is formed between adjacent second disconnection parts D2. This gap is used for light to pass through, increasing the light-transmitting distance on the vertical electrode P. The vertical electrode P extending along the second direction N2 includes the second disconnection parts D2, so that the light-transmitting area of the vertical electrode P is increased. Since the second disconnection part D2 disconnects the vertical electrode P, a vertical electrode P including the second disconnection parts D2 is composed of at least two second disconnection parts D2 arranged in a floating state. The gap between the second disconnection parts D2 is not blocked by the vertical electrode P, effectively increasing the light-transmitting area of the touch display panel 100.

[0056] When the horizontal electrode T includes the first disconnection part D1 and the vertical electrode P includes the second disconnection part D2, the light entering the light sensor opening 3 can be increased, further improving the light transmittance of the touch display panel 100. When the horizontal electrode T and the vertical electrode P of the touch display panel 100 are used in cooperation with the light sensor of the touch display panel 100, the light transmittance of the light sensor can be effectively increased, and thus the sensing effect of the light sensor can be improved. It should be noted that Figure 1 The light sensor opening 3 is exemplarily shown. The light sensor opening 3 is used for light to pass through. The light sensor is used in cooperation with the touch display panel, and the light sensor can be arranged corresponding to the light sensor opening 3. It should be noted that the "corresponding" relationship involved in the present invention can be a one-to-one corresponding relationship, or other "corresponding" relationships adapted to achieve the purpose of the present invention, such as a corresponding relationship formed by adaptation in shape to achieve the purpose of the invention or other corresponding relationships in terms of quantity, etc.

[0057] The touch display panel 100 provided in this embodiment is provided with at least one horizontal electrode T extending along the first direction N1 and at least one vertical electrode P extending along the second direction N2 in the display area 10. The horizontal electrode T and the vertical electrode P intersect with each other. And by setting that at least one horizontal electrode T includes a first disconnection portion D1 arranged at intervals; and / or, at least one vertical electrode P includes a second disconnection portion D2 arranged at intervals, so that the horizontal electrode T and the vertical electrode P can allow light to pass through the gap between adjacent first disconnection portions D1, or the gap between adjacent second disconnection portions D2, or the gap between adjacent first disconnection portions D1 and second disconnection portions D2, which increases the field of view for the light sensor to collect light, preferably improves the light transmittance of the touch display panel 100, and further improves the light transmittance of the light sensor opening 3 of the touch display panel 100 to light.

[0058] Optionally, Figure 2 is a schematic structural diagram of another touch display panel provided by an embodiment of the present invention. On the basis of the above embodiment, referring to Figure 2 , the first disconnection portion D1 of the horizontal electrode T and the second disconnection portion D2 of the vertical electrode P are arranged corresponding to each other.

[0059] Specifically, by setting like this, the horizontal electrode T and the vertical electrode P are both disconnected in the same area, so as to further increase the photosensitive field angle of the light sensor corresponding to both the first disconnection portion D1 of the horizontal electrode T and the second disconnection portion D2 of the vertical electrode P, and further improve the light transmittance of the touch display panel 100, and further improve the sensitivity of the light sensor to light collection.

[0060] It should be noted that, in order to facilitate reflecting the positional relationship between the pixel opening and the light sensor opening 3 and the horizontal electrode and the vertical electrode in the drawings, Figure 2 the positional relationship between the pixel 2 and the light sensor opening 3 and the horizontal electrode and the vertical electrode is exemplarily shown. Since the pixel 2 is arranged in the pixel opening and the light sensor is arranged in the light sensor opening 3, Figure 2 the positions of the pixel 2 and the light sensor opening 3 are exemplarily shown, which can indirectly reflect the positions of the pixel opening and the light sensor.

[0061] Optionally, Figure 3 is a schematic structural diagram of yet another touch display panel provided by an embodiment of the present invention. Figure 4 is a schematic structural diagram of yet another touch display panel provided by an embodiment of the present invention. On the basis of the above embodiment, in combination with Figure 3 and Figure 4, the touch display panel 100 may further include a substrate 1, pixels 2 disposed on one side of the substrate 1, and a photosensor opening 3 disposed on the side of the pixels 2 away from the substrate 1; adjacent two horizontal electrodes T and adjacent two vertical electrodes P enclose a first region S1; the pixels 2 include sub-pixels 21 of at least three light-emitting colors, and the orthographic projection of the sub-pixels 21 on the substrate 1 is located within the orthographic projection of the first region S1 on the substrate 1; the orthographic projection of the horizontal electrodes T on the substrate 1 and the orthographic projection of the vertical electrodes P on the substrate 1 do not overlap with the orthographic projection of the sub-pixels 21 on the substrate 1; the orthographic projection of the horizontal electrodes T on the substrate 1 and the orthographic projection of the vertical electrodes P on the substrate 1 do not overlap with the orthographic projection of the photosensor opening 3 on the substrate 1.

[0062] Specifically, the substrate 1 may include an array substrate 1. The array substrate 1 may be provided with a driving circuit layer. The pixels 2 are disposed on one side of the substrate 1. The pixels 2 are driven to emit light by the driving circuit layer of the substrate 1. The touch display panel 100 may further include a pixel defining layer 30. The pixel defining layer 30 forms a plurality of pixel openings (not shown in the figure). The pixels 2 are disposed in the pixel openings. The photosensor opening 3 may be disposed on the side of the pixels 2 away from the substrate 1. No light-blocking metal wires such as horizontal electrodes T or vertical electrodes P are provided in the photosensor opening 3. The photosensor may include photosensor devices such as a photosensitive camera and a photosensitive sensor. The photosensor (not shown in the figure) may be disposed on one side of the touch display panel and is correspondingly disposed with the photosensor opening 3.

[0063] Setting that the orthographic projection of the horizontal electrodes T on the substrate 1 and the orthographic projection of the vertical electrodes P on the substrate 1 do not overlap with the orthographic projection of the sub-pixels 21 on the substrate 1 can preferably avoid the light shielding of the horizontal electrodes T and the vertical electrodes P on the light of each sub-pixel 21, and further improve the display effect of the touch display panel 100.

[0064] Setting that the orthographic projection of the horizontal electrodes T on the substrate 1 and the orthographic projection of the vertical electrodes P on the substrate 1 do not overlap with the orthographic projection of the photosensor opening 3 on the substrate 1 can preferably improve the light transmittance of the horizontal electrodes T and the vertical electrodes P corresponding to the photosensor opening 3 to light, and further improve the sensitivity of the photosensor to light collection.

[0065] Optionally, on the basis of the above embodiments, continue to refer to Figure 4, the horizontal electrode T may include a first horizontal electrode T1 and a second horizontal electrode T2. The first horizontal electrode T1 includes a first disconnection portion D1; the second horizontal electrode T2 is continuously arranged; the first horizontal electrode T1 and the second horizontal electrode T2 are alternately arranged; the vertical electrode P includes a first vertical electrode P1 and a second vertical electrode P2. The first vertical electrode P1 includes a second disconnection portion D2; the second vertical electrode P2 is continuously arranged; the first vertical electrode P1 and the second vertical electrode P2 are alternately arranged; the first disconnection portion D1 of the first horizontal electrode T1 and the second disconnection portion D2 of the first vertical electrode P1 are correspondingly arranged in the second region S2, and the orthographic projection of the optical sensor opening 3 on the substrate 1 is located within the orthographic projection of the second region S2 on the substrate 1. Optionally, the first horizontal electrode T1 and the second vertical electrode P2 partially overlap; optionally, the first vertical electrode P1 and the second horizontal electrode T2 partially overlap.

[0066] Specifically, the first horizontal electrode T1 and the second horizontal electrode T2 are alternately arranged. It should be noted that the ratio of the first horizontal electrode T1 to the second horizontal electrode T2 is not limited to 1:1. For example, one, two or more than two second horizontal electrodes T2 may be arranged between every two first horizontal electrodes T1 including the first disconnection portion D1, and no limitation is made here.

[0067] Similarly, the first vertical electrode P1 and the second vertical electrode P2 are alternately arranged. It should be noted that the ratio of the first vertical electrode P1 to the second vertical electrode P2 is not limited to 1:1. For example, one, two or more than two second vertical electrodes P2 may be arranged between every two first vertical electrodes P1 including the second disconnection portion D2, and no limitation is made here.

[0068] The fact that the second horizontal electrode T2 is continuously arranged means that the second horizontal electrode T2 does not have the first disconnection portion D1 and does not form a gap. The fact that the second vertical electrode P2 is continuously arranged means that the second vertical electrode P2 does not have the second disconnection portion D2 and does not form a gap.

[0069] The first disconnection portion D1 of the first horizontal electrode T1 and the second disconnection portion D2 of the first vertical electrode P1 are correspondingly arranged in the second region S2. The orthographic projection of the optical sensor opening 3 on the substrate 1 is located within the orthographic projection of the second region S2 on the substrate 1. Since the second region S2 is the region formed by the first disconnection portion D1 of the first horizontal electrode T1 and the second disconnection portion D2 of the first vertical electrode P1, the optical sensor can have a relatively high light transmittance in a large viewing field range, further improving the sensitivity of the optical sensor to light collection.

[0070] Optionally, on the basis of the above embodiments, the first horizontal electrode T1 and the second vertical electrode P2 partially overlap; optionally, the first vertical electrode P1 and the second horizontal electrode T2 partially overlap. The overlapping position of the first horizontal electrode T1 and the second vertical electrode P2 can be bridged or an insulating layer can be provided. The first disconnection portion D1 and the second disconnection portion D2 can be floatingly arranged. It should be noted that the horizontal electrode T and the vertical electrode P are arranged on the same layer, and a double layer can be provided only at the overlapping position of the horizontal electrode T and the vertical electrode P for bridging.

[0071] Optionally, Figure 5 is a schematic structural diagram of another touch display panel provided by an embodiment of the present invention. On the basis of the above embodiments, refer to Figure 5 , at least one second horizontal electrode T2 includes a first bending portion T21, and the first bending portion T21 is arranged on at least one side of the photosensor opening 3; at least one second vertical electrode P2 includes a second bending portion P21, and the second bending portion P21 is arranged on at least one side of the photosensor opening 3; the first bending portion T21 and the second bending portion P21 enclose a third region S3, and the orthographic projection of the third region S3 on the substrate 1 does not completely surround the orthographic projection of the photosensor opening 3 on the substrate 1; the third region S3 includes at least one opening K1. Optionally, at least one side of the orthographic projection of the photosensor opening 3 on the substrate 1 is directly opposite to the orthographic projection of the opening K1 on the substrate 1.

[0072] Specifically, the first bending portion T21 refers to an electrode of the second horizontal electrode T2 with a bent portion on the basis of a straight wire routing. The shape of the first bending portion T21 can include at least two broken line segments, arcs or semi - circles, etc.

[0073] The second bending portion P21 refers to an electrode of the second vertical electrode P2 with a bent portion on the basis of a straight wire routing. The shape of the second bending portion P21 can include at least two broken line segments, arcs or semi - circles, etc. The first bending portion T21 and the second bending portion P21 can form the third region S3. The orthographic projection of the first bending portion T21 on the substrate 1 and the orthographic projection of the second bending portion P21 on the substrate 1 can partially overlap. Since the third region S3 includes at least one opening K1, and at least one side of the orthographic projection of the photosensor opening 3 on the substrate 1 is directly opposite to the orthographic projection of the opening K1 on the substrate 1, at least one side of the photosensor opening 3 whose orthographic projection on the substrate 1 is arranged within the orthographic projection of the third region S3 on the substrate 1 can pass through the position of the opening K1, which can increase the viewing angle of light sensing. With this setting, the setting density of the photosensor opening 3 can be further increased, the light transmittance of the touch display panel 100 can be further increased, and thus the sensitivity of the photosensor to light collection can be further improved.

[0074] Optionally, Figure 6It is a schematic structural diagram of another touch display panel provided by an embodiment of the present invention. On the basis of the above embodiment, refer to Figure 6 , the touch display panel 100 may further include a first pixel unit 4. The first pixel unit 4 includes four sub-pixels 21 and four third regions S3; the first pixel unit 4 is centered on the second region S2; each third region S3 includes a single opening K1; in each first pixel unit 4, at most one opening K1 of each third region S3 faces the sub-pixel 21 of the first pixel unit 4.

[0075] Specifically, in an alternative embodiment, in the defined first pixel unit 4, there are two pixels 2. Each pixel 2 includes a red sub-pixel R, a blue sub-pixel B, and a green sub-pixel G. The two pixels 2 may share sub-pixels 21 of two emission colors, for example, sharing the blue sub-pixel B and the red sub-pixel R. The first pixel unit 4 is centered on the second region S2. The second region S2 is a region surrounded by the first disconnection portion D1 of the first horizontal electrode T1 and the second disconnection portion D2 of the first vertical electrode P1. The first pixel unit 4 includes four third regions S3. The third region S3 is a region surrounded by the first bending portion T21 of the second horizontal electrode T2 and the second bending portion P21 of the second vertical electrode P2.

[0076] Setting each third region S3 to include a single opening K1 can not only maintain the touch area of the touch display panel 100, but also improve the light transmittance of the touch display panel 100. Setting that in each first pixel unit 4, at most one opening K1 of each third region S3 faces the sub-pixel 21 of the first pixel unit 4 can make the light emission of the pixel 2 more uniform and effectively improve the display effect of the touch display panel 100.

[0077] Optionally, Figure 7 It is a schematic structural diagram of another touch display panel provided by an embodiment of the present invention. Figure 8 It is a schematic structural diagram of another touch display panel provided by an embodiment of the present invention. On the basis of the above embodiment, in combination with Figure 7 and Figure 8 , the third region S3 may include three of the first side a1, the second side a2, the third side a3, or the fourth side a4. The first side a1 and the second side a2 are oppositely arranged, and the first side a1 and the second side a2 are connected through the third side a3 or the fourth side a4; alternatively, the third side a3 and the fourth side a4 are oppositely arranged, and the third side a3 and the fourth side a4 are connected through the first side a1 or the second side a2; the openings K1 of the two third regions S3 located at the diagonal positions of the first pixel unit 4 are not oppositely arranged.

[0078] Specifically, when the first pixel unit 4 is quadrilateral, an opening K1 can be provided in each of the third regions S3 at the vertex positions of the first pixel unit 4. Among the two third regions S3 at the diagonal positions of the first pixel unit 4, the opening K1 of one of the third regions S3 can be provided at a position corresponding to the first side a1, and the opening K1 of the other third region S3 can be provided at a position corresponding to the first side a1, the third side a3, or the fourth side a4.

[0079] It should be noted that Figure 7 exemplarily shows the case where the third region S3 includes the second side a2, the third side a3, and the fourth side a4, and no limitation is made here.

[0080] In an alternative embodiment, continue to refer to Figure 8 , the direction of the opening K1 of each third region S3 at the vertex position of the first pixel unit 4 can be set to rotate in the clockwise direction or the counterclockwise direction. For example, in the same first pixel unit 4, the opening K1 of the third region S3 at the 12 o'clock direction can be provided at a position corresponding to the first side a1, that is, the third region S3 at the 12 o'clock direction includes the second side a2, the third side a3, and the fourth side a4. The opening K1 of the third region S3 at the 3 o'clock direction can be provided at a position corresponding to the third side a3, that is, the third region S3 at the 3 o'clock direction includes the first side a1, the second side a2, and the fourth side a4. The opening K1 of the third region S3 at the 6 o'clock direction can be provided at a position corresponding to the second side a2, that is, the third region S3 at the 6 o'clock direction includes the first side a1, the third side a3, and the fourth side a4. The opening K1 of the third region S3 at the 9 o'clock direction can be provided at a position corresponding to the fourth side a4, that is, the third region S3 at the 9 o'clock direction includes the first side a1, the second side a2, and the third side a3, and no limitation is made here.

[0081] In another alternative embodiment, continue to refer to Figure 8, the openings K1 of the two third regions S3 located at the diagonal positions of the first pixel unit 4 are provided on different sides. For example, in the same first pixel unit 4, the opening K1 of the third region S3 located at the 6 o'clock direction can be provided at the position corresponding to the first side a1, that is, the third region S3 located at the 6 o'clock direction includes the second side a2, the third side a3, and the fourth side a4. The opening K1 of the third region S3 located at the 9 o'clock direction can be provided at the position corresponding to the first side a1, that is, the third region S3 located at the 9 o'clock direction includes the second side a2, the third side a3, and the fourth side a4. The opening K1 of the third region S3 located at the 12 o'clock direction can be provided at the position corresponding to the fourth side a4, that is, the third region S3 located at the 12 o'clock direction includes the first side a1, the second side a2, and the third side a3. The opening K1 of the third region S3 located at the 3 o'clock direction can be provided at the position corresponding to the third side a3, that is, the third region S3 located at the 3 o'clock direction includes the first side a1, the second side a2, and the fourth side a4, and no limitation is made here.

[0082] It should be noted that the openings K1 of the two third regions S3 located at the diagonal positions of the first pixel unit 4 are not oppositely arranged, which can make the optical signals collected by each optical sensor more uniform, and can also make the light transmission of the touch display panel 100 more uniform, thereby improving the touch effect of the touch display panel 100 while improving the light collection sensitivity of the optical sensor, and can also improve the display uniformity of the touch display panel 100.

[0083] Optionally, Figure 9 is a schematic structural diagram of another touch display panel provided by an embodiment of the present invention. On the basis of the above embodiment, refer to Figure 9 , the touch display panel may further include a second pixel unit 6. The second pixel unit 6 includes four sub-pixels 21 and four second regions S2; the second pixel unit 6 is centered on the third region S3; each third region S3 includes a single opening K1. The touch display panel 100 may further include a minimum unit 5. The minimum unit 5 includes four second pixel units 6; in a minimum unit 5, the opening K1 direction of the third region S3 corresponding to the sub-pixels 21 of at least one emission color is complementary to the opening K1 direction of the third region S3 corresponding to the sub-pixels 21 of the same emission color in the adjacent second pixel unit 6.

[0084] Specifically, in a minimum unit 5, the opening K1 direction of the third region S3 corresponding to the sub-pixel 21 is complementary to the opening K1 direction of the third region S3 corresponding to the sub-pixel 21 with the same emission color in the adjacent second pixel unit 6. This means that the number of openings K1 of the third region S3 facing the red sub-pixels is the same as or approximately the same as the number of openings K1 of the third region S3 facing the green sub-pixels and the number of openings K1 of the third region S3 facing the blue sub-pixels. Such a setting can make the emission colors of the sub-pixels 21 in a minimum unit 5 more uniform, make the light transmittance between adjacent minimum units 5 as identical as possible, effectively avoid color deviation, and further improve the display effect of the touch display panel 100 and the photosensitive effect of the optical sensor.

[0085] Optionally, Figure 10 is a schematic structural diagram of another touch display panel provided by an embodiment of the present invention. Based on the above embodiment, refer to Figure 10 , the distance H1 between the orthographic projection of the first boundary L1 of the transverse electrode T close to the optical sensor opening 3 on the substrate 1 and the orthographic projection of the second boundary L2 of the optical sensor opening 3 close to the transverse electrode T on the substrate 1 is greater than or equal to 2 μm and less than or equal to 5 μm; the distance H2 between the orthographic projection of the third boundary L3 of the longitudinal electrode P close to the optical sensor opening 3 on the substrate 1 and the orthographic projection of the fourth boundary L4 of the optical sensor opening 3 close to the longitudinal electrode P on the substrate 1 is greater than or equal to 2 μm and less than or equal to 5 μm.

[0086] Specifically, H1 refers to the minimum distance between the orthographic projection of the first boundary L1 of the transverse electrode T on the substrate 1 and the second boundary L2 of the optical sensor opening 3. H2 refers to the minimum distance between the orthographic projection of the third boundary L3 of the longitudinal electrode P on the substrate 1 and the orthographic projection of the fourth boundary L4 of the optical sensor opening 3 on the substrate 1. Such a setting can avoid the transverse electrode T and the longitudinal electrode P from blocking the optical sensor opening 3, can effectively increase the field of view angle of the optical sensor, and further improve the sensitivity of the optical sensor to light collection. On the other hand, such a setting can also ensure the touch areas of the transverse electrode T and the longitudinal electrode P, and improve the touch effect of the touch display panel 100.

[0087] Optionally, the widths of the transverse electrode T and the longitudinal electrode P are the same. Such a setting can make the manufacturing processes of the transverse electrode T and the longitudinal electrode P simple, facilitate manufacturing, and reduce the manufacturing cost.
