Description

[0001] This application is a divisional application with the application date of December 30, 2019, application number 201911395938.7, and the invention name is "Display panel and display device".

Technical field

[0002] The present invention relates to the field of display technology, and in particular to a display panel and a display device. [Background Technology]

[0003] In the prior art, display panels with camera functions typically have a through hole or groove within the display panel to accommodate the camera assembly, without pixels being placed within the through hole or groove. However, this arrangement prevents images from being displayed in the through hole or groove, not only failing to achieve a true full-screen display but also affecting the continuity of the displayed image. [Summary of the invention]

[0004] In view of this, embodiments of the present invention provide a display panel and a display device, which optimize the full-screen design and improve the continuity of the display image while ensuring that the optical component arrangement area has a high light transmittance.

[0005] In one aspect, an embodiment of the present invention provides a display panel, including:

[0006] substrate;

[0007] A display area, the display area including an optical component arrangement area;

[0008] Pixels, the pixels including a first pixel, the first pixel including a first pixel circuit and a first light-emitting element electrically connected, wherein the first light-emitting element is located in the optical component setting area;

[0009] A carrier substrate, on which the first pixel circuit is arranged, and the carrier substrate is bent relative to the base substrate.

[0010] On the other hand, an embodiment of the present invention provides a display device including the above-mentioned display panel.

[0011] One of the above technical solutions has the following beneficial effects:

[0012] In the technical solution provided in the embodiment of the present invention, a carrier substrate is set, and then the first pixel circuit in the first pixel is set on the carrier substrate. Only the first light-emitting element electrically connected to the first pixel circuit is retained in the optical component setting area, and there is no need to set the first pixel circuit. Since 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 is set in the optical component setting area, the optical component setting area can still be guaranteed to have a high light transmittance; moreover, the light emission of the first light-emitting element can also enable the optical component setting area to display the picture normally, thereby realizing a true full-screen design, and improving the continuity of the overall picture presented by the display panel, thereby optimizing the display effect.

[0031] In order to better understand the technical solution of the present invention, the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] It should be understood that the embodiments described are only a portion of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative work are within the scope of protection of the present invention.

[0033] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The singular forms "a", "an", "the" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0034] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0035] It should be understood that although the terms "first" and "second" may be used to describe light-emitting elements in embodiments of the present invention, these light-emitting elements should not be limited to these terms. These terms are merely used to distinguish light-emitting elements from each other. For example, a first light-emitting element may also be referred to as a second light-emitting element, and similarly, a 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.

[0036] An embodiment of the present invention provides a display panel, such as Figure 1 As shown, Figure 1 Schematic diagram of the base substrate and the carrier substrate in the display panel provided by the embodiment of the present invention, the display panel includes: a base substrate 1; a display area 2, the display area 2 includes an optical component setting area 3; a pixel 4, the pixel 4 includes a first pixel 5, the first pixel 5 includes an electrically connected first pixel circuit 6 and a first light-emitting element 7, wherein the first light-emitting element 7 is located in the optical component setting area 3; a carrier substrate 8, the first pixel circuit 6 is provided on the carrier substrate 8, as shown in FIG. Figure 2 and Figure 3 As shown, Figure 2 A side view of a display panel provided by an embodiment of the present invention, Figure 3 This is a top view of the display panel provided in an embodiment of the present invention, in which one side of the carrying substrate 8 is in contact with one side of the base substrate 1, and the carrying substrate 8 is bent to the back of the base substrate 1. The base substrate 1 includes a surface located on the same side as the light-emitting surface of the display panel and a non-light-emitting surface, that is, the carrying substrate 8 is bent to the non-light-emitting side of the base substrate 1.

[0037] In the display panel provided in the embodiment of the present invention, a carrier substrate 8 is set, and then the first pixel circuit 6 in the first pixel 5 is set on the carrier substrate 8. Only the first light-emitting element 7 electrically connected to the first pixel circuit 6 is retained in the optical component setting area 3, and there is no need to set the first pixel circuit 6. Since 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 set in the optical component setting area 3, the optical component setting area 3 can still be guaranteed to have a high light transmittance; moreover, the light emission of the first light-emitting element 7 can also enable the optical component setting area 3 to display the picture normally, thereby realizing a true full-screen design, and improving the continuity of the overall picture presented by the display panel, thereby optimizing the display effect.

[0038] Alternatively, as Figure 4 As shown, Figure 4This is a structural schematic diagram of a base substrate and a carrier substrate in a display panel provided by an embodiment of the present invention. The base substrate 1 and the carrier substrate 8 are respectively flexible substrates, and the base substrate 1 and the carrier substrate 8 are integrally formed. That is, when forming the display panel, a flexible substrate is used as a substrate, and the flexible substrate is divided into the base substrate 1 and the carrier substrate 8. After corresponding film layers are formed on the base substrate 1 and the carrier substrate 8, respectively, the carrier substrate 8 is bent relative to the base substrate 1. This arrangement not only ensures the stability of the connection between the carrier substrate 8 and the base substrate 1, reduces the risk of the carrier substrate 8 breaking with the base substrate 1 when bent, but also facilitates the wiring of the connection lines between the first pixel circuit 6 and the first light-emitting element 7.

[0039] Optionally, see again Figure 2 The carrying substrate 8 is bent and arranged on the side of the base substrate 1 facing away from the light-emitting surface of the display panel. When the carrying substrate 8 is bent to the back of the base substrate 1, the carrying substrate 8 will not occupy the front space of the display panel, thereby ensuring that the front of the display panel is an area where the image can be displayed, further optimizing the full-screen design of the display panel.

[0040] Alternatively, as Figure 5 and Figure 6 As shown, Figure 5 A schematic structural diagram of a first connecting line provided in an embodiment of the present invention, Figure 6 for Figure 5 In the cross-sectional view along the A1-A2 direction, the first pixel circuit 6 and the first light-emitting element 7 are electrically connected via a first connecting trace 9. The first connecting trace 9 includes a transparent connecting trace 10, and the transparent connecting trace 10 is located in the optical component installation area 3. By configuring the portion of the first connecting trace 9 located in the optical component installation area 3 as the transparent connecting trace 10, it is possible to reduce the obstruction of the optical component installation area 3 by this portion of the connecting trace, further improving the light transmittance of the optical component installation area 3, thereby further increasing the amount of external ambient light incident on the camera assembly through the optical component installation area 3, and optimizing the imaging quality.

[0041] Further, please see again Figure 5 , the first connecting trace 9 also includes a bent metal wire 11; the carrier substrate 8 includes a bending area 12. When the carrier substrate 8 includes the bending area 12, the bending area 12 contacts the base substrate 1, thereby realizing the connection between the carrier substrate 8 and the base substrate 1; optionally, the base substrate 1 may include a bending area 12, and the bending area 12 contacts the carrier substrate 8, thereby realizing the connection between the base substrate 1 and the carrier substrate 8.

[0042] The bent metal wire 11 is located at least in the bending region 12. Since metal has good ductility and is less likely to break when bent, the portion of the first connecting trace 9 located in the bending region 12 is provided as the bent metal wire 11. This effectively reduces the risk of breaking the first connecting trace 9 due to bending, thereby improving the stability of the connection between the first pixel circuit 6 and the first light-emitting element 7, and thereby improving the reliability of the light emission of the first light-emitting element 7.

[0043] Alternatively, as Figure 7 and Figure 8 As shown, Figure 7 A schematic structural diagram of a second connection line provided in an embodiment of the present invention, Figure 8 for Figure 7 In the cross-sectional view along the B1-B2 direction, the first pixel circuit 6 and the first light-emitting element 7 are electrically connected via a second connecting trace 13, which is a metal connecting trace. By forming the second connecting trace 13 from a metal material with a low resistivity, the load on the second connecting trace 13 can be reduced, thereby reducing the attenuation of the drive current signal during transmission along the second connecting trace 13. This improves the transmission stability of the drive current signal, thereby ensuring that the brightness of the first light-emitting element 7 approaches the standard brightness.

[0044] Alternatively, as Figure 9 As shown, Figure 9 Another expanded schematic diagram of the base substrate and the carrier substrate in the display panel provided in an embodiment of the present invention, the display area 2 has a first edge 14, a second edge 15 and a first vertex angle 16 defined by the first edge 14 and the second edge 15; the optical component setting area 3 is located on the side of the display area 2 close to the first vertex angle 16; the carrier substrate 8 includes a first carrier substrate 17 and a second carrier substrate 18, the first carrier substrate 17 is located on the side of the base substrate 1 close to the first edge 14, and the second carrier substrate 18 is located on the side of the base substrate 1 close to the second edge 15; the first pixel circuit 6 is respectively provided on the first carrier substrate 17 and the second carrier substrate 18.

[0045] If the carrier substrate 8 is only provided on one side of the base substrate 1, and for example the carrier substrate 8 is provided on the upper side of the base substrate 1, then the connection lines 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 base substrate 1 to the optical component setting area 3, resulting in a denser distribution of connection lines in the upper half of the optical component setting area 3, which in turn leads to poor uniformity in light transmittance between the upper and lower halves of the optical component setting area 3. However, by providing the first carrier substrate 17 and the second carrier substrate 18 on both sides of the base substrate 1, respectively, and distributing the first pixel circuit 6 on the first carrier substrate 17 and the second carrier substrate 18, please refer again to Figure 9For the connecting lines between the first pixel circuit 6 and the first light-emitting element 7 in the first carrier substrate 17, this part of the connecting lines can pass through the first edge 14 of the base substrate 1 and extend to the optical component setting area 3. For the connecting lines between the first pixel circuit 6 and the first light-emitting element 7 in the second carrier substrate 18, this part of the connecting lines can pass through the second edge 15 of the base substrate 1 and extend to the optical component setting area 3, so that the connecting lines are dispersed and extended into the optical component setting area 3 in different directions, avoiding the overly dense distribution of lines in a certain area of ​​the optical component setting area 3, thereby effectively improving the uniformity of the transmittance in different areas of the optical component setting area 3.

[0046] Alternatively, as Figure 10 As shown, Figure 10 This is a structural schematic diagram of the optical component setting area provided in an embodiment of the present invention. The display panel also includes a camera assembly 19, which is located in the optical component setting area 3; the optical component setting area 3 only includes a high-transmittance area 20, and in the direction perpendicular to the plane of the substrate 1, the high-transmittance area 20 and the camera assembly 19 completely overlap.

[0047] In the prior art, if one wishes to set pixels in the optical component setting area, the optical component setting area is typically configured to include a high-transmittance area and a transition area surrounding the high-transmittance area. The high-transmittance area is typically used to set the light-emitting elements of the pixels, and the transition area is used to set the pixel circuits corresponding to the light-emitting elements in the high-transmittance area. The camera assembly is typically located in the high-transmittance area. Since the pixel circuits require a certain amount of space within the optical component setting area, the area occupied by the optical component setting area is relatively large, thereby affecting the overall image presentation. In other words, in order to achieve normal operation of the front camera while maintaining a full-screen display, there will be an area on the display panel that has a different pixel density and transmittance than the normal display area, namely the optical component setting area. This area is larger than the actual area of ​​the camera, increasing the impact on the overall display effect. Considering the uniformity of the display effect across the entire display panel, the area of ​​the optical component setting area should be as small as possible while ensuring the normal operation of the optical components. In the embodiment of the present invention, by setting the first pixel circuit 6 on the carrier substrate 8, there is no need to set a transition zone in the optical component setting area 3, and only the high-transmittance area 20 is retained in the optical component setting area 3, so that the occupied area of ​​the optical component setting area 3 is the same as the area of ​​the camera assembly 19, which greatly reduces the space occupied by the optical component setting area 3 and further reduces the impact of the optical component setting area 3 on the image displayed by the display panel.

[0048] Optionally, see again Figure 10 In order to ensure that the optical component setting area 3 occupies a smaller space, the length of the edge of the optical component setting area 3 is L, 2mm≤L≤3.5mm.

[0049] Optionally, see again Figure 1 , the display area 2 also includes a first display area 21, and the pixel 4 also includes a second pixel 22 located in the first display area 21, and the second pixel 22 includes an electrically connected second pixel circuit 23 and a second light-emitting element 24; the density of the second light-emitting element 24 in the first display area 21 is the same as the density of the first light-emitting element 7 in the optical component setting area 3, that is, the density of the pixels 4 in the optical component setting area 3 and the first display area 21 is the same, so that the display quality of the optical component setting area 3 and the first display area 21 is the same, and the optical component setting area 3 will not have a negative impact on the overall display screen, thereby optimizing the display effect of the overall screen. In addition, it should be noted that since the number of metal traces forming the pixel circuit is much greater than the number of metal traces forming the light-emitting element, therefore, under the premise that the first pixel circuit 6 is not set in the optical component setting area 3, increasing the number of first light-emitting elements 7 in the optical component setting area 3 to make it the same as the density of the second light-emitting element 24 will not have a significant impact on the transmittance of the optical component setting area 3.

[0050] Alternatively, as Figure 11 As shown, Figure 11 Schematic diagram of the structure of the first driving line provided in an embodiment of the present invention, the carrier substrate 8 includes a bending area 12. When the carrier substrate 8 includes the bending area 12, the bending area 12 contacts the base substrate 1, thereby realizing the connection between the carrier substrate 8 and the base substrate 1; optionally, the base substrate 1 may include a bending area 12, and the bending area 12 contacts the carrier substrate 8, thereby realizing the connection between the base substrate 1 and the carrier substrate 8. The bending area 12 includes a bending axis 25, which extends along the first direction; the display panel includes a first driving line 26, such as a gate scan line and a reference voltage signal line, and the first driving line 26 includes a first A driving line 27 and a first B driving line 28, wherein the first B driving line 28 extends along the first direction within the first display area 21; the first A driving line 27 includes a first routing segment 29 and a second routing segment 30, and the first routing segment 29 extends along the first direction within the first display area 21; the second routing segment 30 extends from the end of the first routing segment 29 to the carrier substrate 8, and the second routing segment 30 is electrically connected to the first pixel circuit 6.

[0051] By extending the second routing segment 30 in the first A driving line 27 to the carrier substrate 8 and electrically connecting it to the first pixel circuit 6, the first A driving line 27 can be prevented from passing through the optical component setting area 3, thereby preventing the first A driving line 27 from affecting the transmittance of the optical component setting area 3.

[0052] In addition, it should be noted that since the first routing segment 29 is wound on the carrier substrate 8, the routing length of the first A driving line 27 is greater than the routing length of the first B driving line 28, resulting in the load of the first A driving line 27 being greater than the load of the first B driving line 28. The resistance of the first A driving line 27 can be reduced by increasing the line width of the first A driving line 27, thereby reducing the load of the first A driving line 27, ensuring that the loads of the first A driving line 27 and the first B driving line 28 are consistent, thereby ensuring that the attenuation degree of the signal when transmitted on the first A driving line 27 and the first B driving line 28 is consistent.

[0053] Alternatively, as Figure 12 As shown, Figure 12 A structural schematic diagram of the second driving line provided in an embodiment of the present invention, wherein the carrier substrate 8 includes a bending area 12. When the carrier substrate 8 includes the bending area 12, the bending area 12 contacts the base substrate 1, thereby realizing the connection between the carrier substrate 8 and the base substrate 1; optionally, the base substrate 1 may include a bending area 12, and the bending area 12 contacts the carrier substrate 8, thereby realizing the connection between the base substrate 1 and the carrier substrate 8. The bending area 12 includes a bending axis 25, which extends along the first direction; the display panel includes a second drive line 31, such as a data line and a power signal line; the second drive line 31 includes a second A drive line 32 and a second B drive line 33, wherein the second B drive line 33 is located in the first display area 21, and the second B drive line 33 extends along the second direction, and the second direction intersects with the first direction; the second A drive line 32 passes through the first display area 21 through the optical component setting area 3 and extends to the supporting substrate 8, and the second A drive line 32 includes a third routing segment 43, the third routing segment 43 is located in the optical component setting area 3, and the third routing segment 43 is a non-straight routing line, such as a wavy routing line.

[0054] Because the second-A driving lines 32 pass through the optical component installation area 3 via the first display area 21, when the display panel is in camera mode, ambient light enters the camera assembly 19 and is diffracted in the narrow gaps between the second-A driving lines 32, causing variations in light intensity and, in turn, distortion in the captured image. By configuring the third routing segments 43 of the second-A driving lines 32 within the optical component installation area 3 as non-linear routing, the irregularly arranged third routing segments 43 can be used to mitigate the diffraction effect on light, thereby alleviating the problem of image distortion caused by diffraction.

[0055] Alternatively, as Figure 13 As shown, Figure 13Another structural schematic diagram of the second driving line provided in an embodiment of the present invention, the carrier substrate 8 includes a bending area 12. When the carrier substrate 8 includes the bending area 12, the bending area 12 contacts the base substrate 1, thereby realizing the connection between the carrier substrate 8 and the base substrate 1; optionally, the base substrate 1 may include a bending area 12, and the bending area 12 contacts the carrier substrate 8, thereby realizing the connection between the base substrate 1 and the carrier substrate 8. The bending area 12 includes a bending axis 25, which extends along the first direction; the display area 2 also includes a frame area 34 surrounding the optical component setting area 3; the display panel includes a second driving line 31, and the second driving line 31 includes a second A driving line 32 and a second B driving line 33, wherein the second B driving line 33 extends along the second direction in the first display area 21, and the second direction intersects with the first direction; the second A driving line 32 extends through the first display area 21 to the frame area 34 and extends to the supporting substrate 8, and the second A driving line 32 does not overlap with the optical component setting area 3; the second A driving line 32 includes a fourth routing segment 35, and the fourth routing segment 35 is located in the frame area 34, and the multiple fourth routing segments 35 included in the multiple second A driving lines 32 are arranged in different layers; the multiple fourth routing segments 35 are arranged in different layers, which can save the space occupied by the routing on the plane where the display panel is located and save the frame width. Typically, the driving line is a metal line, and the second A driving line 32 does not overlap with the optical component setting area 3, that is, the driving line does not pass through the optical component setting area 3, which can further improve the transmittance of the optical component setting area 3 and avoid the influence of the diffraction effect when the light passes between the driving lines on the imaging effect of the optical component.

[0056] like Figure 14 As shown, Figure 14 This is a schematic diagram of the membrane layer structure of the fourth routing segment provided in an embodiment of the present invention. Taking the fourth routing segment 35 as an example, which includes multiple fourth A routing segments 36 and multiple fourth B routing segments 37, and the fourth A routing segment 36 and the fourth B routing segment 37 are arranged on different layers, two adjacent fourth routing segments 35 (corresponding to one fourth A routing segment 36 and one fourth B routing segment 37) are arranged on different layers. Under the premise of avoiding mutual interference between the signals of the two adjacent fourth routing segments 35, the interval between the two adjacent fourth routing segments 35 can be reduced, thereby reducing the space occupied by all the fourth routing segments 35 in the border area 34, reducing the width of the border area 34, and thus reducing the impact of the border area 34 on the display screen.

[0057] Alternatively, as Figure 15 As shown, Figure 15This is another structural diagram of the second driving line provided by an embodiment of the present invention. A bending area 12 is included between the carrier substrate 8 and the base substrate 1. The bending area 12 includes a bending axis 25. The bending axis 25 extends along the first direction. The display panel includes a second driving line 31. The second driving line 31 extends along the second direction. The second direction intersects with the first direction. The second driving line 31 includes a second A driving line 32 and a second B driving line 33. The second B driving line 33 is located in the first display area 21. The second A driving line 32 extends along the second direction. The second A driving line 32 passes through the first display area 21, penetrates the optical component setting area 3 and extends to the supporting substrate 8. The second A driving line 32 includes a fifth routing segment 38 and a sixth routing segment 39. The fifth routing segment 38 is located in the first display area 21, and the sixth routing segment 39 is located in the optical component setting area 3. The sixth routing segment 39 is a transparent routing segment; the line width of the sixth routing segment 39 is greater than the line width of the fifth routing segment 38, and / or, in the direction perpendicular to the plane where the display panel is located, the thickness of the sixth routing segment 39 is greater than the thickness of the fifth routing segment 38.

[0058] With such a configuration, on the one hand, by configuring the sixth routing segment 39 in the second A driving line 32 located in the optical component setting area 3 as a transparent routing segment, the degree of shielding of the optical component setting area 3 by the sixth routing segment 39 can be reduced, thereby improving the transmittance of the optical component setting area 3; 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 routing segment 39 can be reduced by further adjusting the line width or thickness of the sixth routing segment 39, so that the load of the second A driving line 32 and the load of the second B driving line 33 tend to be consistent, thereby ensuring that the attenuation degree of the signal when transmitted on the load of the second A driving line 32 and the second B driving line 33 tends to be consistent.

[0059] Further, if Figure 16 As shown, Figure 16 Another expanded schematic diagram of the base substrate and the carrier substrate in the display panel provided in an embodiment of the present invention, the pixel 4 also includes a third pixel 40 formed on the carrier substrate 8, the third pixel 40 includes an electrically connected third pixel circuit 41 and a third light-emitting element 42; the density of the third light-emitting element 42 on the carrier substrate 8 is less than the density of the second light-emitting element 24 in the first display area 21.

[0060] Since a carrier substrate 8 is required in the display panel provided by the embodiment of the present invention, a third pixel 40 for display is further provided on the carrier substrate 8, in combination with the Figure 3The carrier substrate 8 can be bent toward the side of the display panel to display auxiliary information, such as remaining battery power, date, time, and prompt information, in the area where the carrier substrate 8 is located, thereby optimizing the function of the display panel. Furthermore, by reducing the density of the third light-emitting elements 42, sufficient space can be ensured on the carrier substrate 8 for the first pixel circuit 6.

[0061] The embodiment of the present invention further provides a display device, such as Figure 17 As shown, Figure 17 This is a schematic diagram of the structure of a display device provided by an embodiment of the present invention, and the display device includes the above-mentioned display panel 100, wherein the specific structure of the display panel 100 has been described in detail in the above-mentioned embodiment and will not be repeated here. Figure 17 The display device shown is for illustrative purposes only. The display device may be any electronic device with a display function, such as a mobile phone, a tablet computer, a laptop computer, an e-reader, or a television.

[0062] Since the display device provided by the embodiment of the present invention includes the above-mentioned display panel 100, the display device is adopted, by setting a carrier substrate 8, and then setting the first pixel circuit 6 in the first pixel 5 on the carrier substrate 8, and only the first light-emitting element 7 electrically connected to the first pixel 5 is retained in the optical component setting area 3, and there is no need to set the first pixel circuit 6, thereby ensuring that the optical component setting area 3 has a high light transmittance; moreover, the light emission of the first light-emitting element 7 can also enable the optical component setting area 3 to display the picture normally, thereby realizing a true full-screen design, and improving the continuity of the overall picture presented by the display panel, thereby optimizing the display effect.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
