The substrate 100 may include a base and a first conductive layer, a second conductive layer, and a third conductive layer that are arranged on one side of the base and stacked.

An orthographic projection of the first bottom surface on the substrate 100 is located within an orthographic projection of the first top surface on the substrate 100, that is, a size of the first bottom surface is smaller than that of the first top surface, so that the isolation structure 400 generally has a big-end-up structure, so as to form a recess on one side of the isolation structure 400.

Alternatively, as shown in
In other embodiments, as shown in
In some embodiments, the display panel further includes an auxiliary conductive layer 240 located in the main display region ZA, and the auxiliary conductive layer 240 is electrically connected to the light-transmitting conductive layer 200, so that the light-transmitting conductive layer 200 may be connected to other components through the auxiliary conductive layer 240, and the light-transmitting conductive layer 200 may have a fixed potential.
Optionally, the auxiliary conductive layer 240 is arranged on a side of the isolation structure 400 close to the substrate 100. An orthographic projection of the auxiliary conductive layer on the substrate 100 is located within a range of an orthographic projection of the isolation structure 400 on the substrate 100, so as to facilitate the connection between the auxiliary conductive layer 240 and the isolation structure 400. Optionally, a shape of the auxiliary conductive layer 240 is the same as that of the isolation structure 400. That is, the auxiliary conductive layer 240 also has an auxiliary opening in the main display region ZA, and the auxiliary opening is located under the isolation opening 410. An area of the auxiliary opening is larger than that of the isolation opening 410, which facilitates the manufacturing of the light-emitting unit 600 and ensures a light-emitting area of the light-emitting unit 600.
In some embodiments, the auxiliary conductive layer 240 and the light-transmitting conductive layer 200 are connected to each other to realize the connection between the isolation structure 400 in the main display region ZA and the light-transmitting conductive layer 200, and have a same fixed potential. Further, the light-transmitting conductive layer 200 may extend from the light-transmitting display region TA to the main display region ZA, and the light-transmitting conductive layer 200 located in the main display region ZA forms the auxiliary conductive layer 240. That is, the light-transmitting conductive layer 200 and the auxiliary conductive layer 240 are arranged on a same layer and made of a same material. For example, the light-transmitting conductive layer 200 and the auxiliary conductive layer are made of a same material, so as to increase a contact area between the light-transmitting conductive layer 200 and the auxiliary conductive layer 240, improve strength of the connection thereof, and also simplify a manufacturing process of the display panel.
Optionally, the insulating protective layer 300 extends from the light-transmitting display region TA to the main display region ZA, covering the light-transmitting conductive layer 200 located in the main display region ZA. Optionally, the communication hole 320 includes a first communication hole 321 located in the main display region ZA and arranged through the insulating protective layer 300, and the isolation structure 400 is electrically connected to the auxiliary conductive layer 240 in the main display region ZA through the first communication hole 321 provided in the insulating protective layer 300. Therefore, the isolation structure 400 is electrically connected to the light-transmitting conductive layer 200 through the auxiliary conductive layer 240. In addition, both the main display region ZA and the light-transmitting display region TA are provided with the insulating protective layer 300, which can make structures of the light-transmitting display region TA and the main display region ZA tend to be consistent and improve display uniformity of the light-transmitting display region TA and the main display region ZA.
The first communication hole 321 is positioned in a variety of manners. Optionally, the first communication hole 321 may be distributed throughout the main display region ZA of the display panel 10.
In such optional embodiments, the first communication hole 321 is located in the main display region ZA rather than the light-transmitting display region TA, so that the first communication hole 321 may not occupy an area of the light-transmitting display region TA. More first light-transmitting openings 420 may be appropriately provided in the light-transmitting display region TA, or an area of the first light-transmitting opening 420 may be appropriately increased in the light-transmitting display region TA, so as to further improve the light transmittance of the light-transmitting display region TA. Moreover, at least part of the light-transmitting conductive layer 200 and the auxiliary conductive layer 240 in the main display region ZA are connected to each other, so that the light-transmitting conductive layer 200 can be connected to the isolation structure 400 through the first communication hole 321 located in the main display region ZA.
In some optional embodiments, the display panel 10 includes a light-emitting unit 600, the light-emitting unit 600 includes a first light-emitting unit 610 and a second light-emitting unit 620 located in different isolation openings 410 (i.e., different pixel openings 520), and the first communication hole 321 is located between the first light-emitting unit 610 and the second light-emitting unit 620. On the one hand, an influence of the first communication hole 321 on the light-emitting effect is ameliorated. On the other hand, a spacing between the first light-emitting unit 610 and the second light-emitting unit 620 is larger, which facilitates the arrangement of a larger-sized first communication hole 321, ensures a yield of connection between the isolation structure 400 and the light-transmitting conductive layer 200, and reduces signal transmission impedance.
In some optional embodiments, as shown in
In some other embodiments, an area of an orthographic projection of the second light-transmitting opening 430 on the substrate 100 is smaller than an area of an orthographic projection of the first light-transmitting opening 420 on the substrate 100. That is, the size of the second light-transmitting opening 430 is smaller than that of the first light-transmitting opening 420, so as to ensure that the main display region ZA has a sufficient area for the communication hole 320.
Optionally, the second light-transmitting opening 430 is located between the first light-emitting unit 610 and the second light-emitting unit 620 adjacent to each other. For example, when the first light-emitting unit 610 and the second light-emitting unit 620 are distributed in an array along a first direction X and a second direction Y, the orthographic projection of the second light-transmitting opening 430 on the substrate 100 is located between orthographic projections of the first light-emitting unit 610 and the second light-emitting unit 620 adjacent to each other along the first direction X or the second direction Y on the substrate 100, so as to appropriately increase the size of the second light-transmitting opening 430.
Optionally, when the main display region ZA is provided with both the second light-transmitting opening 430 and the first communication hole 321, the first light-emitting unit 610 and the second light-emitting unit 620 are distributed in an array along the first direction X and the second direction Y, and the orthographic projection of at least one first communication hole 321 on the substrate 100 and the orthographic projection of the second light-transmitting opening 430 on the substrate 100 are arranged side by side along the first direction X, or the second direction Y, or the first direction X and the second direction Y.
For example, when the first communication hole 321 and the second light-transmitting opening 430 are correspondingly arranged between the first light-emitting unit 610 and the second light-emitting unit 620 arranged side by side along the first direction X, the first communication hole 321 and the second light-transmitting opening 430 are arranged side by side along the second direction Y, to reduce an overall size of the second light-transmitting opening 430 and the first communication hole 321 in the second direction Y and appropriately increase the sizes of the second light-transmitting opening 430 and the first communication hole 321 at the same time.
Alternatively, when the first communication hole 321 and the second light-transmitting opening 430 are correspondingly arranged between the first light-emitting unit 610 and the second light-emitting unit 620 arranged side by side along the second direction Y, the first communication hole 321 and the second light-transmitting opening 430 are arranged side by side along the first direction X, to reduce an overall size of the second light-transmitting opening 430 and the communication hole 320 in the first direction X and appropriately increase the sizes of the second light-transmitting opening 430 and the communication hole 320 at the same time.
Optionally, a projection of the insulating protective layer 300 located in the main display region ZA on the substrate 100 at least partially overlaps with the orthographic projection of the second light-transmitting opening 430 on the substrate 100, and the insulating protective layer 300 can be exposed through the second light-transmitting opening 430.
As described above, the light-emitting unit 600 includes a first light-emitting unit 610 and a second light-emitting unit 620 located in different isolation openings 410 (i.e., different pixel openings 520), and the first light-transmitting opening 420 is located between the first light-emitting unit 610 and the second light-emitting unit 620. The first light-transmitting opening 420 is correspondingly arranged between the first light-emitting unit 610 and the second light-emitting unit 620, which can ameliorate an influence of the first light-transmitting opening 420 on the light-emitting effect of the light-emitting unit 600. “The first light-transmitting opening 420 is located between the first light-emitting unit 610 and the second light-emitting unit 620” means that in a top view of the display panel 10, the first light-transmitting opening 420 is located between an orthographic projection of the first light-emitting unit 610 on the substrate 100 and an orthographic projection of the second light-emitting unit 620 on the substrate 100. For example, the first light-transmitting opening 420 has a first orthographic projection on the substrate 100, the first light-emitting unit 610 has a second orthographic projection on the substrate 100, and the second light-emitting unit 620 has a third orthographic projection on the substrate. The first orthographic projection is between the second orthographic projection and the third orthographic projection.
In some optional embodiments, the light-emitting layer comprises a plurality of light-emitting units 600, the plurality of light-emitting units 600 are arranged in an array, and at least one first light-transmitting opening 420 is located between two adjacent light-emitting units 600 in a same row or column, to ameliorate the influence of the first light-transmitting opening 420 on the light-emitting effect of the light-emitting unit 600. “At least one first light-transmitting opening 420 is located between two adjacent light-emitting units 600 in a same row or column” means that in the top view of the display panel 10, the first light-transmitting opening 420 is correspondingly located between two adjacent light-emitting units 600 in a same row or column. For example, when the first light-transmitting opening 420 has a first orthographic projection on the substrate 100, the light-emitting unit 600 has a second orthographic projection on the substrate 100, and the first orthographic projection is located between two adjacent second orthographic projections in a same row or column.
Optionally, the plurality of light-emitting units 600 are arranged in an array along the first direction X and the second direction Y, the light-transmitting opening 420 includes a first light-transmitting sub-opening and a second light-transmitting sub-opening, a length of the first light-transmitting sub-opening in the first direction X is greater than a length thereof in the second direction Y, and a length of the second light-transmitting sub-opening in the second direction Y is greater than a length thereof in the first direction X. Through the arrangement of the first light-transmitting sub-opening and the second light-transmitting sub-opening with different sizes, the first light-transmitting opening 420 can better match a gap between two adjacent light-emitting units 600, a distribution area of the first light-transmitting opening 420 can be increased, and the light transmittance of the display panel 10 can be improved.
Optionally, the first light-transmitting sub-opening is arranged between two light-emitting units 600 adjacent to each other along the second direction Y. An extension size of the gap between the two light-emitting units 600 adjacent to each other along the second direction Y is larger in the first direction X, so that the arrangement of the first light-transmitting sub-opening between the two light-emitting units 600 adjacent to each other along the second direction Y can appropriately increase a distribution area of the first light-transmitting sub-opening.
Optionally, the second light-transmitting sub-opening is arranged between two light-emitting units 600 adjacent to each other along the first direction X. An extension size of the gap between the two light-emitting units 600 adjacent to each other along the first direction X is larger in the second direction Y, so that the arrangement of the second light-transmitting sub-opening between the two light-emitting units 600 adjacent to each other along the first direction X can appropriately increase a distribution area of the second light-transmitting sub-opening.
Optionally, the plurality of light-emitting units 600 may further include a plurality of third light-emitting units 630, the plurality of first light-emitting units 610 and the plurality of second light-emitting units 620 are alternately arranged along the second direction Y to form a first pixel column 601, the plurality of third light-emitting units 630 are arranged along the second direction Y to form a second pixel column 602, and the first pixel column 601 and the second pixel column 602 are alternately arranged along the first direction X. The orthographic projection of the first light-transmitting opening 420 on the substrate 100 is located between the orthographic projections of the first light-emitting unit 610 and the second light-emitting unit 620 adjacent to each other along the first direction X, or the second direction Y, or the first direction X and the second direction Y on the substrate 100.
In such embodiments, the first pixel column 601 includes first light-emitting units 610 and second light-emitting units 620 alternately arranged along the second direction Y, the second pixel column 602 includes third light-emitting units 630 arranged along the second direction Y, and the first pixel column 601 and the second pixel column 602 are alternately arranged along the first direction X. A spacing between the first light-emitting unit 610 and the second light-emitting unit 620 may be larger than a spacing between the first light-emitting unit 610 and the third light-emitting unit 630 or between the second light-emitting unit 620 and the third light-emitting unit 630. The first light-transmitting opening 420 is correspondingly arranged between the first light-emitting unit 610 and the second light-emitting unit 620 adjacent to each other along the first direction X, or the second direction Y, or the first direction X and the second direction Y, that is, the first light-transmitting opening 420 is arranged in a larger gap, which can appropriately increase the distribution area of the first light-transmitting opening 420, thereby improving the light transmittance of the display panel 10.
Optionally, one of the first light-emitting unit 610 and the second light-emitting unit 620 is a blue light-emitting unit 600, and the other is a red light-emitting unit 600. The third light-emitting unit 630 is, for example, a green light-emitting unit 600. Therefore, the first light-emitting unit 610 and the second light-emitting unit 620 in the first pixel column 601 may be combined with the third light-emitting unit 630 in the second pixel column 602 to form a unit group for emitting white light.
Optionally, the third light-emitting unit 630 in the second pixel column 602 is correspondingly located between the first light-emitting unit 610 and the second light-emitting unit 620 adjacent to each other in the first pixel column 601. That is, the first pixel column 601 and the second pixel column 602 are misaligned in the first direction X, which can reduce the spacing between the first light-emitting unit 610 and the third light-emitting unit 630 and the spacing between the second light-emitting unit 620 and the third light-emitting unit 630, thereby improving the display effect.
Optionally, two second light-emitting units 620 and two first light-emitting units 610 are arranged on a peripheral side of the third light-emitting unit 630, and the two first light-emitting units 610 and the two second light-emitting units 620 are alternately arranged on the peripheral side of the third light-emitting unit 630. The spacing between the first light-emitting unit 610 and the third light-emitting unit 630 and the spacing between the second light-emitting unit 620 and the third light-emitting unit 630 can be further reduced, thereby improving the display effect.

The orthographic projection of the shielding portion 250 on the substrate 100 at least partially overlaps with the orthographic projection of the first light-transmitting opening 420 on the substrate 100, that is, the shielding portion 250 of the light-transmitting conductive portion 201 is arranged correspondingly to the light-transmitting opening 420, so that during the subsequent manufacturing of the touch electrode 900, the problem of parasitic capacitance produced between the touch electrode 900 and the wires in the substrate 100 through the first light-transmitting opening 420 can be alleviated, and the process performance of the display panel 10 can be improved.
Optionally, an area of the orthographic projection of the shielding portion 250 on the substrate 100 is greater than an area of an orthographic projection of the connecting portion 260 on the substrate 100. The shielding portion 250 has a larger area, so that the light-transmitting conductive portion 201 can block more signals passing through the first light-transmitting opening 420, which better alleviates the problem of parasitic capacitance produced between the touch electrode 900 and the wires in the substrate 100 through the first light-transmitting opening 420.
Optionally, the orthographic projection of the first light-transmitting opening 420 on the substrate 100 is located within a range of the orthographic projection of the shielding portion 250 on the substrate 100.

Lengths of the first light-emitting unit 610 and the second light-emitting unit 620 in the first direction X are less than lengths thereof in the second direction, so that a gap between the first light-emitting unit 610 and the second light-emitting unit 620 adjacent to each other in the first direction X is larger than a gap in the second direction Y.
In such optional embodiments, the shielding portion 250 is correspondingly located between the first light-emitting unit 610 and the second light-emitting unit 620 adjacent to each other, which can ameliorate a short-circuit connection between the shielding portion 250 and the first electrode 111 for driving the first light-emitting unit 610 and the second light-emitting unit 620 and can also ameliorate an influence of the shielding portion 250 on light-emitting effects of the first light-emitting unit 610 and the second light-emitting unit 620.
“The shielding portion 250 is located between the first light-emitting unit 610 and the second light-emitting unit 620” means that in the top view of the display panel, the shielding portion 250 is correspondingly located between the first light-emitting unit 610 and the second light-emitting unit 620.

Optionally, the orthographic projection of the shielding portion 250 on the substrate 100 is located between orthographic projections of the first light-emitting unit 610 and the second light-emitting unit 620 adjacent to each other along the first direction X, or the second direction Y, or the first direction X and the second direction Y on the substrate 100. Spacings between the first light-emitting unit 610 and the second light-emitting unit 620 adjacent to each other along the first direction X and between the first light-emitting unit 610 and the second light-emitting unit 620 adjacent to each other along the second direction Y are both larger, and the shielding portion 250 is such positioned that it is easy to appropriately increase a distribution area of the shielding portion 250.

The third direction intersects the first direction X and the second direction Y in a same plane. The third direction may be a direction P or Q in
In such embodiments, the shielding portion 250 is correspondingly located between two light-emitting units 600 adjacent to each other along the first direction X or the second direction Y, and the third communication hole 323 is correspondingly located on a side of the first light-emitting unit 610 or the second light-emitting unit 620 in the third direction, so that there is an angle position setting between the third communication hole 323 and the closest light-emitting unit 600. The third communication hole 323 and the shielding portion 250 are distributed at intervals around the first light-emitting unit 610 or the second light-emitting unit 620, so as to ameliorate interference from the relative position between the communication hole 320 and the shielding portion 250, which facilitates an appropriate increase in the size of the shielding portion 250, thereby facilitating an appropriate increase in the size of the first light-transmitting opening 420. In addition, a sufficient space can also be left for the arrangement of the third communication hole 323.
Optionally, an angle between the first reference connection line and the first direction X or the second direction Y ranges from 30 degrees to 60 degrees, to prevent an influence on the arrangement of the communication hole 320 due to an excessively short distance between the communication hole 320 and the shielding portion 250 and an excessively short distance between the first light-transmitting opening 420 and the communication hole 320 caused by an excessively small or large angle.
Optionally, the angle between the first reference connection line and the first direction X or the second direction Y is 45 degrees, so that the shielding portion 250 and the third communication hole 323 can be relatively evenly distributed in a plane.

The second reference connection line intersects the first direction X and the second direction Y in a same plane. That is, the third communication hole 323 is located on a side of the shielding portion 250 in the third direction, so that the third communication hole 323 and the shielding portion 250 can be located on a peripheral side of the first light-emitting unit 610 or the second light-emitting unit 620, which facilitates an appropriate increase in the distribution area of the communication hole 320 and the shielding portion.

Optionally, the third communication hole 323 may be located between the first light-emitting unit 610 and the third light-emitting unit 630, and the third communication hole 323 may alternatively be located between the second light-emitting unit 620 and the third light-emitting unit 630. The third communication hole 323 is correspondingly located between two light-emitting units 600 with a smaller spacing, so that the third communication hole 323 may not occupy an excessively large space, which facilitates the arrangement of the shielding portion 250 and the first light-transmitting opening 420.
In some other embodiments, the orthographic projection of the third communication hole 323 on the substrate 100 may alternatively be located between the orthographic projection of the first light-emitting unit 610 on the substrate 100 and the orthographic projection of the second light-emitting unit 620 on the substrate 100. The third communication hole 323 is correspondingly arranged between two light-emitting units 600 with a larger spacing, which facilitates an appropriate increase in the size of the third communication hole 323.
In the above embodiments, the light-transmitting conductive portions 201 are arranged independently from each other, that is, each first light-transmitting opening 420 is correspondingly provided with an independently arranged light-transmitting conductive portion 201, which can minimize the distribution area of the light-transmitting conductive portion 201, thereby ameliorating interference between arrangement of the light-transmitting conductive portion 201 and other signal lines, also facilitating an appropriate increase in the size of the light-emitting unit 600, and improving the display effect.
When the light-transmitting conductive portions 201 are arranged independently from each other, the connecting portion 260 of each light-transmitting conductive portion 201 is located on a side of the shielding portion 250 in the third direction. There is a third reference connection line between the connecting portion 260 and the shielding portion 250. The third reference connection line intersects the first direction X and the second direction Y in a same plane. That is, each shielding portion 250 has a connecting portion 260 protruding along the third direction. The size of the connecting portion 260 may be smaller, as long as the size can ensure that the connecting portion 260 and the isolation structure 400 can be electrically connected to each other through the third communication hole 323.
The third reference connection line may be arranged in a same manner as the first reference connection line. For example, an angle between the third reference connection line and the first direction X or the second direction Y ranges from 30 degrees to 60 degrees. Optionally, the angle between the third reference connection line and the first direction X or the second direction Y is 45 degrees.
Optionally, an area of the orthographic projection of the shielding portion 250 on the substrate 100 is greater than an area of an orthographic projection of the connecting portion 260 on the substrate 100. The shielding portion 250 has a larger size, and the first light-transmitting opening 420 may have a larger size, thereby improving the light transmittance of the display panel 10. The connecting portion 260 has a smaller size, which can reduce an overall distribution size of the light-transmitting conductive portion 201, thereby ameliorating interference between arrangement of the light-transmitting conductive portion 201 and other signal lines, also facilitating an appropriate increase in the size of the light-emitting unit 600, and improving the display effect.

That is, the shielding portions 250 of the two adjacent light-transmitting conductive portions 201 are connected to each other through the connecting portion 260. The size of the connecting portion 260 is generally smaller than that of the shielding portion 250.
