The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It should be understood that the term "and/or" as used herein is merely one type of association that describes an associated object, meaning that three relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
It should be understood that although the terms first and second may be used to describe the light emitting elements in the embodiments of the present invention, the light emitting elements should not be limited to these terms. These terms are only used to distinguish the light emitting elements from each other. For example, the first light emitting element may also be referred to as a second light emitting element, and similarly, the second light emitting element may also be referred to as a first light emitting element without departing from the scope of embodiments of the present invention.

In the display panel provided in the embodiment of the present invention, by providing the carrier substrate 8, the first pixel circuit 6 in the first pixel 5 is disposed on the carrier substrate 8, and only the first light emitting element 7 electrically connected to the first pixel circuit 6 is remained in the optical component disposing region 3, and there is no need to further provide the first pixel circuit 6, because the number of metal traces forming the light emitting element is much less than the number of metal traces forming the pixel circuit, when only the first light emitting element 7 is disposed in the optical component disposing region 3, it can still be ensured that the optical component disposing region 3 has a higher light transmittance; moreover, the first light-emitting element 7 emits light to enable the optical component arrangement area 3 to normally display a picture, so that a real full-screen design is realized, the continuity of the whole picture displayed by the display panel is improved, and the display effect is optimized.
Alternatively, as shown in fig. 4, fig. 4 is a schematic structural diagram of a substrate board and a carrier board in a display panel provided in an embodiment of the present invention, the substrate board 1 and the carrier board 8 are respectively flexible boards, and the substrate board 1 and the carrier board 8 are integrally formed, that is, when forming a display panel, a flexible substrate is used as a substrate, the flexible substrate is divided into a substrate 1 and a bearing substrate 8, after the corresponding film layers are respectively formed on the substrate base plate 1 and the bearing base plate 8, the bearing base plate 8 is bent relative to the substrate base plate 1, and by adopting the setting mode, the stability of connection between the bearing base plate 8 and the substrate base plate 1 is ensured, the risk of breakage between the bearing base plate 8 and the substrate base plate 1 when the bearing base plate 8 is bent is reduced, and wiring of wiring between the first pixel circuit 6 and the first light-emitting element 7 is facilitated.
Optionally, referring to fig. 2 again, the carrier substrate 8 is bent and disposed on a side of the substrate 1 opposite to the light exit surface of the display panel, and the carrier substrate 8 is bent to the back of the substrate 1, so that the carrier substrate 8 does not occupy the front space of the display panel, thereby ensuring that the front of the display panel is an area capable of displaying pictures, and further optimizing the overall screen design of the display panel.
Alternatively, as shown in fig. 5 and fig. 6, fig. 5 is a schematic structural diagram of a first connection trace provided in the embodiment of the present invention, and fig. 6 is a cross-sectional view taken along a direction a1-a2 in fig. 5, the first pixel circuit 6 and the first light emitting element 7 are electrically connected through the first connection trace 9, the first connection trace 9 includes a transparent connection line 10, and the transparent connection line 10 is located in the optical component disposing area 3. Through setting up the part that lies in optical component setting area 3 in walking line 9 with first connecting to transparent connecting line 10, can reduce sheltering from of this part connecting line to optical component setting area 3, further improved optical component setting area 3's luminousness to further increased the light quantity of the external environment light of inciding to the camera subassembly via optical component setting area 3, optimized the imaging quality.
Further, referring to fig. 5 again, the first connecting trace 9 further includes a bending metal wire 11; the bearing base plate 8 comprises a bending area 12, and when the bearing base plate 8 comprises the bending area 12, the bending area 12 is in contact with the substrate base plate 1, so that the bearing base plate 8 is connected with the substrate base plate 1; optionally, the substrate base plate 1 may include a bending region 12, and the bending region 12 is in contact with the carrier base plate 8, so as to achieve connection between the substrate base plate 1 and the carrier base plate 8.
The bending metal wire 11 is at least located in the bending area 12. Because the ductility of metal is better, difficult fracture takes place during the bending, consequently, set up the part that lies in bending zone 12 in the first connecting line 9 as bending metal line 11, can effectively reduce the cracked risk of first connecting line 9 that leads to by buckling, improved the stability of connecting between first pixel circuit 6 and the first light emitting component 7, and then improved the luminous reliability of first light emitting component 7.
Optionally, as shown in fig. 7 and fig. 8, fig. 7 is a schematic structural diagram of a second connection trace provided by the embodiment of the present invention, and fig. 8 is a cross-sectional view of fig. 7 along a direction B1-B2, where the first pixel circuit 6 and the first light emitting element 7 are electrically connected through the second connection trace 13, and the second connection trace 13 is a metal connection line. The second connecting wire 13 is made of a metal material with lower resistivity, so that the load of the second connecting wire 13 can be reduced, the attenuation degree of a driving current signal during transmission on the second connecting wire 13 is reduced, the transmission stability of the driving current signal is improved, and the brightness of the first light-emitting element 7 is close to the standard brightness.
Alternatively, as shown in fig. 9, fig. 9 is another expanded schematic view of a substrate and a carrier substrate in a display panel provided in the embodiment of the present invention, and the display area 2 has a first edge 14, a second edge 15, and a first top corner 16 defined by the first edge 14 and the second edge 15; the optical member disposition region 3 is located on a side of the display region 2 near the first vertex 16; the bearing base plate 8 comprises a first bearing base plate 17 and a second bearing base plate 18, wherein the first bearing base plate 17 is positioned on one side of the substrate base plate 1 close to the first edge 14, and the second bearing base plate 18 is positioned on one side of the substrate base plate 1 close to the second edge 15; the first carrier substrate 17 and the second carrier substrate 18 are provided with first pixel circuits 6, respectively.
If the carrier substrate 8 is disposed on only one side of the substrate 1, taking the example that the carrier substrate 8 is disposed on the upper side of the substrate 1, then the connection traces between the first pixel circuit 6 and the first light emitting element 7 on the carrier substrate 8 all extend from the upper side of the substrate 1 to the optical component disposing region 3, so that the connection traces in the upper half area of the optical component disposing region 3 are distributed densely, and further the light transmittance uniformity of the upper half area and the lower half area of the optical component disposing region 3 is poor. And by providing the first and second carrier substrates 17 and 18 on both sides of the base substrate 1, and the first pixel circuits 6 are disposed on the first carrier substrate 17 and the second carrier substrate 18 in a distributed manner, please refer to fig. 9 again, for the connection tracks between the first pixel circuits 6 and the first light emitting elements 7 in the first carrier substrate 17, the portion of the connection tracks may extend through the first edge 14 of the base substrate 1 to the optic component placement region 3, for the connection tracks between the first pixel circuits 6 and the first light emitting elements 7 in the second carrier substrate 18, the portion of the connection tracks may extend through the second edge 15 of the substrate base 1 to the optical component placement area 3, therefore, the connecting wires are dispersedly extended into the optical component setting area 3 along different directions, the phenomenon that the wires in a certain area in the optical component setting area 3 are distributed too densely is avoided, and the uniformity of the light transmittance in different areas of the optical component setting area 3 is effectively improved.
Alternatively, as shown in fig. 10, fig. 10 is a schematic structural diagram of the optical component arrangement area provided in the embodiment of the present invention, the display panel further includes a camera assembly 19, and the camera assembly 19 is located in the optical component arrangement area 3; the optical component disposition region 3 includes only the high-transmission region 20, and the high-transmission region 20 and the camera head assembly 19 completely overlap in a direction perpendicular to the plane of the substrate base plate 1.
In the prior art, if a pixel is desired to be disposed in an optical component disposing area, the optical component disposing area generally includes a high-transmittance area and a transition area surrounding the high-transmittance area, where the high-transmittance area is generally used for disposing a light emitting element of the pixel, and the transition area is used for disposing a pixel circuit corresponding to the light emitting element in the high-transmittance area, and the camera assembly is generally located in the high-transmittance area. That is, in order to realize normal work of the front camera while displaying on a full screen, a region different from the normal display region in pixel density and light transmittance, namely, an optical component setting region, exists on the display panel, and the area of the region is larger than the actual area of the camera, so that the influence on the overall display effect is increased, and the uniformity of the display effect of the whole display panel is considered, and the smaller the area of the optical component setting region is, the better the optical component setting region is, under the condition that the optical component can normally work. In the embodiment of the present invention, the first pixel circuits 6 are all disposed on the carrier substrate 8, so that no transition region needs to be disposed in the optical component disposing region 3, and only the high-transmittance region 20 is reserved in the optical component disposing region 3, so that the occupied area of the optical component disposing region 3 is the same as the area of the camera assembly 19, the occupied space of the optical component disposing region 3 is reduced to a great extent, and the influence of the optical component disposing region 3 on the displayed picture of the display panel is further reduced.
Optionally, referring to fig. 10 again, in order to ensure that the optical component disposing area 3 occupies a smaller space, the length of the edge of the optical component disposing area 3 is L, and L is greater than or equal to 2mm and less than or equal to 3.5 mm.
Optionally, referring to fig. 1 again, the display area 2 further includes a first display area 21, the pixel 4 further includes a second pixel 22 located in the first display area 21, and the second pixel 22 includes a second pixel circuit 23 and a second light emitting element 24 electrically connected to each other; the density of the second light emitting elements 24 in the first display area 21 is the same as the density of the first light emitting elements 7 in the optical component arrangement area 3, that is, the density of the pixels 4 in the optical component arrangement area 3 and the first display area 21 is the same, so that the display quality of the optical component arrangement area 3 and the display quality of the first display area 21 are the same, the optical component arrangement area 3 does not have adverse effect on the whole display picture, and the display effect of the whole picture is optimized. Moreover, since the number of metal traces forming the pixel circuit is much larger than the number of metal traces forming the light emitting element, on the premise that the first pixel circuit 6 is not disposed in the optical component disposing area 3, the number of the first light emitting elements 7 in the optical component disposing area 3 is increased to be the same as the density of the second light emitting elements 24, and the light transmittance of the optical component disposing area 3 is not greatly affected.
Optionally, as shown in fig. 11, fig. 11 is a schematic structural diagram of the first driving line provided in the embodiment of the present invention, the carrier substrate 8 includes a bending region 12, and when the carrier substrate 8 includes the bending region 12, the bending region 12 contacts with the substrate 1, so as to implement connection between the carrier substrate 8 and the substrate 1; optionally, the substrate base plate 1 may include a bending region 12, and the bending region 12 is in contact with the carrier base plate 8, so as to achieve connection between the substrate base plate 1 and the carrier base plate 8. The bending zone 12 comprises a bending axis 25, the bending axis 25 extending in a first direction; the display panel includes first driving lines 26, such as gate scanning lines and reference voltage signal lines, the first driving lines 26 including first a driving lines 27 and first b driving lines 28, wherein the first b driving lines 28 extend in a first direction within the first display area 21; the first driving line 27 includes a first routing segment 29 and a second routing segment 30, the first routing segment 29 extends in a first direction in the first display area 21; the second wire segment 30 extends from the end of the first wire segment 29 to the carrier substrate 8, and the second wire segment 30 is electrically connected to the first pixel circuit 6.
By extending the second wire segment 30 of the first driving wire 27 to the carrier substrate 8 to be electrically connected to the first pixel circuit 6, the first driving wire 27 can be prevented from penetrating the optical component setting area 3, and the first driving wire 27 can be prevented from affecting the light transmittance of the optical component setting area 3.
In addition, it should be noted that, because the first wire segment 29 is wound on the carrier substrate 8, the first driving wire 27 has a length longer than the second driving wire 28, which results in the load of the first driving wire 27 being greater than the load of the first second driving wire 28, and the resistance of the first driving wire 27 can be reduced by increasing the line width of the first driving wire 27, so as to reduce the load of the first driving wire 27, ensure that the loads of the first driving wire 27 and the second driving wire 28 tend to be consistent, and further ensure that the attenuation degrees of signals transmitted on the first driving wire 27 and the second driving wire 28 tend to be consistent.
Optionally, as shown in fig. 12, fig. 12 is a schematic structural diagram of a second driving line according to an embodiment of the present invention, where the carrier substrate 8 includes a bending region 12, and when the carrier substrate 8 includes the bending region 12, the bending region 12 contacts with the substrate 1, so as to achieve connection between the carrier substrate 8 and the substrate 1; optionally, the substrate base plate 1 may include a bending region 12, and the bending region 12 is in contact with the carrier base plate 8, so as to achieve connection between the substrate base plate 1 and the carrier base plate 8. The bending zone 12 comprises a bending axis 25, the bending axis 25 extending in a first direction; the display panel includes second driving lines 31, such as data lines and power supply signal lines; the second driving lines 31 include second driving lines 32 and second driving lines 33, wherein the second driving lines 33 are located in the first display region 21, the second driving lines 33 extend in a second direction, and the second direction intersects with the first direction; the second driving line 32 passes through the optical component disposing region 3 via the first display region 21 and extends to the carrier substrate 8, the second driving line 32 includes a third routing segment 43, the third routing segment 43 is located in the optical component disposing region 3, and the third routing segment 43 is a non-linear routing, such as a wave-shaped routing.
Since the second driving lines 32 penetrate the optical component installation area 3 through the first display area 21, when the display panel is in the image capturing mode, light of the external environment enters the camera assembly 19, and the light is diffracted in the slits between the second driving lines 32, so that the light intensity is changed, and the captured image is distorted. By arranging the third wire segments 43 in the second driving wires 32 in the optical component arrangement area 3 as non-linear wires, the irregular third wire segments 43 can be used to improve the diffraction effect on light, thereby improving the distortion of the photographed image caused by diffraction.
Optionally, as shown in fig. 13, fig. 13 is another schematic structural diagram of the second driving line provided in the embodiment of the present invention, the carrier substrate 8 includes a bending region 12, and when the carrier substrate 8 includes the bending region 12, the bending region 12 contacts with the substrate 1, so as to implement connection between the carrier substrate 8 and the substrate 1; optionally, the substrate base plate 1 may include a bending region 12, and the bending region 12 is in contact with the carrier base plate 8, so as to achieve connection between the substrate base plate 1 and the carrier base plate 8. The bending zone 12 comprises a bending axis 25, the bending axis 25 extending in a first direction; the display area 2 further includes a rim area 34 surrounding the optical component disposition area 3; the display panel includes a second driving line 31, the second driving line 31 including a second driving line 32 and a second driving line 33, wherein the second driving line 33 extends in a second direction within the first display area 21, the second direction intersecting the first direction; the second driving lines 32 extend to the frame region 34 via the first display region 21 and extend to the carrier substrate 8, and there is no overlap between the second driving lines 32 and the optical component disposing region 3; the second driving lines 32 comprise fourth line segments 35, the fourth line segments 35 are positioned in the frame area 34, and a plurality of fourth line segments 35 comprised by the plurality of second driving lines 32 are arranged in different layers; the fourth routing segments 35 are arranged on different layers, so that the space occupied by the routing on the plane where the display panel is located can be saved, and the width of the frame is saved. Generally, the driving wires are metal wires, and the second driving wires 32 are not overlapped with the optical component setting area 3, that is, the driving wires do not penetrate through the optical component setting area 3, so that the light transmittance of the optical component setting area 3 can be further improved, and meanwhile, the influence of the diffraction effect of light passing through the driving wires on the imaging effect of the optical component is avoided.
As shown in fig. 14, fig. 14 is a schematic diagram of a film structure of a fourth routing segment according to an embodiment of the present invention, in which the fourth routing segment 35 includes a plurality of fourth routing segments 36 and a plurality of fourth routing segments 37, and different layers of the fourth routing segments 36 and the fourth routing segments 37 are set as examples, two adjacent fourth routing segments 35 (corresponding to one fourth routing segment 36 and one fourth routing segment 37) are set on different layers, so that on the premise of avoiding mutual interference between signals of two adjacent fourth routing segments 35, an interval between two adjacent fourth routing segments 35 can be reduced, thereby reducing a space occupied by all fourth routing segments 35 in the frame area 34, reducing a width of the frame area 34, and reducing an influence of the frame area 34 on a display screen.
Alternatively, as shown in fig. 15, fig. 15 is a schematic structural diagram of a second driving line according to an embodiment of the present invention, a bending region 12 is included between the carrier substrate 8 and the substrate 1, the bending region 12 includes a bending axis 25, and the bending axis 25 extends along a first direction; the display panel includes a second driving line 31, the second driving line 31 extending along a second direction, the second direction intersecting the first direction; the second driving lines 31 include second driving lines 32 and second driving lines 33, wherein the second driving lines 33 are located in the first display region 21; the second driving line 32 penetrates through the optical component arrangement area 3 via the first display area 21 and extends to the carrier substrate 8, the second driving line 32 comprises a fifth line segment 38 and a sixth line segment 39, the fifth line segment 38 is located in the first display area 21, the sixth line segment 39 is located in the optical component arrangement area 3, and the sixth line segment 39 is a transparent line segment; the line width of the sixth running line segment 39 is greater than the line width of the fifth running line segment 38, and/or the thickness of the sixth running line segment 39 is greater than the thickness of the fifth running line segment 38 in the direction perpendicular to the plane of the display panel.
With this arrangement, on the one hand, by setting the sixth running line segment 39 in the second driving line 32, which is located in the optical component arrangement area 3, as a transparent running line segment, the degree of shielding of the optical component arrangement area 3 by the sixth running line segment 39 can be reduced, and the light transmittance of the optical component arrangement area 3 can be improved; on the other hand, since the resistivity of the transparent conductive material is greater than that of the metal material, the load of the sixth running line section 39 can be reduced by further adjusting the line width or the thickness of the sixth running line section 39, so that the load of the second driving line 32 and the load of the second driving line 33 tend to be consistent, and the attenuation degree of signals transmitted on the second driving line 32 and the second driving line 33 tends to be consistent.
Further, as shown in fig. 16, fig. 16 is another expanded schematic view of the substrate and the carrier substrate in the display panel according to the embodiment of the present invention, the pixel 4 further includes a third pixel 40 formed on the carrier substrate 8, and the third pixel 40 includes a third pixel circuit 41 and a third light emitting element 42 electrically connected to each other; the density of the third light emitting elements 42 on the carrier substrate 8 is less than the density of the second light emitting elements 24 in the first display area 21.
