Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display panel and a display device. Background Art

[0002] The development of under-display facial recognition technology requires two key aspects: first, the facial recognition display area must have the same display quality as the regular display area; second, the facial recognition display area must meet infrared light transmittance requirements. Generally, high transmittance requires low pixel density, but the pixel density of a screen is closely related to the display quality. Some technologies achieve high transmittance requirements by removing pixels from the facial recognition display area, but this reduces the display quality in this area.

[0003] Other technologies, in order to minimize the display difference between the two areas, adopt the design of deleting the driving circuit of the face recognition display area and using one driving circuit to correspond to multiple light-emitting devices to achieve equal resolution in the two areas, which can also meet the transmittance requirements.

[0004] However, to ensure the continuity of data signals within the surface, the data signals of the conventional display area are wired one-to-one in the face recognition display area, but these connections will reduce the overall transmittance of the face recognition display area.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described here are only used to illustrate and explain the present application and are not used to limit the present application. In this application, the various embodiments can be combined with each other but will not be repeated one by one. In addition, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the drawings; while "inner" and "outer" refer to the outline of the device; the terms "first", "second", "third", etc. are used only as labels and do not impose numerical requirements or establish an order.

[0041] The embodiments of the present application provide a display panel and a display device, which are described in detail below. It should be noted that the order of description of the following embodiments does not limit the preferred order of the embodiments.

[0042] Please refer to Figures 1 to 3 ,exist Figure 1In the embodiment, the first direction F1 may be a direction parallel to one side of the display panel 100 in a top plan view, and may be, for example, a transverse direction of the display panel 100. The second direction F2 may be a direction parallel to the other side of the display panel 100 in a top plan view, and may be a longitudinal direction of the display panel 100. Alternatively, in some embodiments, the first direction F1 and the second direction F2 may not intersect perpendicularly.

[0043] The display panel 100 may have a rectangular shape in a top plan view, but embodiments are not limited thereto. In some embodiments, the display panel 100 may have a rectangular shape with vertical corners or rounded corners in a top plan view. The display panel 100 may include two short sides extending in a first direction F1 and two long sides extending in a second direction F2 in a top plan view.

[0044] An embodiment of the present application provides a display panel 100 , which includes a first display area AA1 and a second display area AA2 located at at least one side of the first display area AA1 . The first display area AA1 is configured to transmit light.

[0045] The display panel 100 includes a plurality of first pixel circuits 11 , a second pixel circuit 12 , a first data line 21 , and a second data line 22 .

[0046] A plurality of first pixel circuits 11 are arranged in the first display area AA1, and one first pixel circuit 11 is correspondingly connected to at least two light emitting devices 01. A plurality of second pixel circuits 12 are arranged in the second display area AA2, and one second pixel circuit 12 is correspondingly connected to one light emitting device 01.

[0047] A plurality of first data lines 21 are provided in the first display area AA1 and the second display area AA2, each of which is connected to the first pixel circuit 11 and the second pixel circuit 12. At least one second data line 22 is provided in the second display area AA2 and outside the first display area AA1, and is connected to the second pixel circuit 12.

[0048] The second data line 22 includes a first line 221, a connecting line 223, and a second line 222, which are connected in sequence. The first line 221 and the second line 222 are each connected to a corresponding second pixel circuit 12. At least a portion of the connecting line 223 intersects with the first data line 21 and is disposed in a different layer. The first line 221 and the second line 222 are located on opposite sides of the first display area AA1 and are both separated from the first data line 21. The connecting line 223 is arranged around the periphery of the first display area AA1.

[0049] The length of the second data line 22 is greater than that of the first data line 21 . The second data line 22 further includes an auxiliary portion 24 , which is connected to the connecting trace 223 .

[0050] It is understood that since the second data line 22 is not connected to the first pixel circuit 11 in the first display area AA1, the second data line 22 is routed around the first display area AA1 via the connecting trace 223, thereby reducing the number of data lines in the first display area AA1 and improving the light transmittance of the first display area AA1. Furthermore, since the second data line 22 is routed in a winding manner, its length is longer than that of the first data line 21. Therefore, an auxiliary portion 24 is used to connect the second data line 22 to reduce the load on the second data line 22, thereby reducing the load difference between the first data line 21 and the second data line 22, thereby improving display uniformity in the first display area AA1.

[0051] It should be noted that the lengths of the second data line 22 and the first data line 21 are their respective lengths within the total display area. The first display area AA1 and the second display area AA2 are connected to form the total display area. The second display area AA2 is located on at least one side of the first display area AA1. For example, the second display area AA2 surrounds the first display area AA1, or the second display area AA2 partially surrounds the first display area AA1.

[0052] Optionally, in some embodiments of the present application, the display panel 100 further includes third data lines 23 disposed in the second display area AA2. The third data lines 23 extend along the second direction F2 and pass through the entire second display area AA2. The third data lines 23 and the first data lines 21 are disposed in the same layer and spaced apart. In the first direction F1, the third data lines 23 are disposed on opposite sides of all first data lines 21. In the first direction F1, the second sub-line 22b is disposed between two adjacent third data lines 23.

[0053] In the second display area AA2, the length of the third data line 23 is shorter than that of the second data line 22. The auxiliary portion 24 is used to connect the second data line 22 to reduce the load on the second data line 22, thereby reducing the load difference between the third data line 23 and the second data line 22, thereby improving the display uniformity of the entire display area.

[0054] Secondly, the second display area AA2 and the first display area AA1 are both areas including pixels for displaying images. The first display area AA1 is configured to provide a light-transmitting channel for the camera module.

[0055] Optionally, the camera module may be a camera module for facial recognition, which includes a transmitter and a receiver, wherein the transmitter is configured to transmit infrared light, and the receiver is configured to receive infrared light reflected from a human face.

[0056] exist Figure 1In the embodiment, the display panel 100 includes two first display areas AA1. One first display area AA1 is configured to provide a light transmission channel for the transmitter, and the other first display area AA1 is configured to provide a light transmission channel for the receiver. However, the present invention is not limited thereto. For example, one first display area AA1 may provide a light transmission channel for both the transmitter and the receiver. Alternatively, the display panel 100 includes one first display area AA1, and the first display area AA1 is configured to provide a light transmission channel for a conventional camera module, such as a single-camera module, a multi-camera module, or an infrared camera module.

[0057] Optionally, the plurality of light-emitting devices 01 include a red light-emitting device R, a green light-emitting device G, and a blue light-emitting device B. In the first display area AA1, a first pixel circuit 11 is connected to at least two red light-emitting devices R, another first pixel circuit 11 is connected to at least two green light-emitting devices G, and yet another first pixel circuit 11 is connected to at least two blue light-emitting devices B. In the second display area AA2, a second pixel circuit 12 is connected to a red light-emitting device R, another second pixel circuit 12 is connected to a green light-emitting device G, and yet another second pixel circuit 12 is connected to a blue light-emitting device B.

[0058] Optionally, in some embodiments, in the first display area AA1, a first pixel circuit 11 is connected to two red light emitting devices R, another first pixel circuit 11 is connected to two green light emitting devices G, and another first pixel circuit 11 is connected to four blue light emitting devices B.

[0059] Optionally, in some embodiments, the plurality of second data lines 22 are divided into two groups. The connecting traces 223 of one group of second data lines 22 are routed toward the left side of the first display area AA1, while the connecting traces 223 of the other group of second data lines 22 are routed toward the right side of the first display area AA1. In other words, the connecting traces of the two groups of second data lines 22 are arranged opposite each other with the first display area AA1 spaced apart. Compared to a single-sided routing method, the bilateral routing method employed in the present embodiment can reduce the load difference between the first data lines 21 and the second data lines 22, as well as reduce the load difference between the second data lines 22.

[0060] Optionally, in some embodiments of the present application, the connecting trace 223 includes a first sub-line 22a, a second sub-line 22b, and a third sub-line 22c, which are connected in sequence. The first sub-line 22a is connected to the first trace 221, and the third sub-line 22c is connected to the second trace. The first sub-line 22a and the third sub-line 22c extend along a first direction F1. The second sub-line 22b, the first data line 21, the first trace 221, and the second trace 222 extend along a second direction F2 that intersects the first direction F1. The first sub-line 22a and the third sub-line 22c intersect the first data line 21 and are arranged in different layers. The second sub-line 22b is spaced apart from the first data line 21.

[0061] Please refer to Figures 2 to 5 The auxiliary portion 24 includes a first auxiliary portion 241 , the first sub-line 22a includes a first end connected to the first trace 221 and a second end connected to the second sub-line 22b , and at least one of the first end and the second end is connected to the first auxiliary portion 241 .

[0062] Optionally, a first auxiliary portion 241 is connected to the first end, and another first auxiliary portion 241 is connected to the second end to reduce the impedance of the second data line 22, thereby reducing the load difference between the first data line 21 and the second data line 22 and improving the display uniformity of the first display area AA1.

[0063] Optionally, in some embodiments of the present application, the first auxiliary portion 241 is connected to the first sub-line 22 a in the same layer, and the first auxiliary portion 241 is extended along the first direction F1.

[0064] Optionally, in some embodiments of the present application, in the first direction F1 , the first sub-line 22 a is extended in a straight line to reduce the load difference between the first data line 21 and the second data line 22 .

[0065] The first sub-line 22a is connected to the second sub-line 22b through the via g1.

[0066] Please refer to Figure 5 and Figure 6 In some embodiments of the present application, the auxiliary portion 24 includes a second auxiliary portion 242, the second sub-line 22b includes a third end connected to the first sub-line 22a and a fourth end connected to the third sub-line 22c, and at least one of the third end and the fourth end is connected to the second auxiliary portion 242.

[0067] Optionally, a second auxiliary portion 242 is connected to the third end, and another second auxiliary portion 242 is connected to the fourth end to reduce the impedance of the second data line 22, thereby reducing the load difference between the first data line 21 and the second data line 22 and improving the display uniformity of the first display area AA1.

[0068] Optionally, in some embodiments of the present application, the second auxiliary portion 242 is connected to the second sub-line 22 b in the same layer, and the second auxiliary portion 242 extends along the second direction F2.

[0069] Optionally, in some embodiments of the present application, in the second direction F2, the second sub-line 22b is extended in a straight line, and the first data line 21 is extended in a zigzag line, so as to reduce the load difference between the first data line 21 and the second data line 22.

[0070] The third sub-line 22c is connected to the second sub-line 22b through the via g1.

[0071] Please refer to Figure 6 and Figure 7 In some embodiments of the present application, the auxiliary portion 24 includes a third auxiliary portion 243, the third sub-line 22c includes a fifth end connected to the second trace 222 and a sixth end connected to the second sub-line 22b, and at least one of the fifth end and the sixth end is connected to the third auxiliary portion 243.

[0072] Optionally, a third auxiliary portion 243 is connected to the fifth end, and another third auxiliary portion 243 is connected to the sixth end to reduce the impedance of the second data line 22, thereby reducing the load difference between the first data line 21 and the second data line 22 and improving the display uniformity of the first display area AA1.

[0073] Optionally, in some embodiments of the present application, the third auxiliary portion 243 is connected to the third sub-line 22 c in the same layer, and the third auxiliary portion 243 is extended along the first direction F1.

[0074] Optionally, in some embodiments of the present application, in the first direction F1 , the third sub-line 22 c is extended in a straight line to reduce the load difference between the first data line 21 and the second data line 22 .

[0075] Optionally, in some embodiments of the present application, a second data line 22 is connected to a column of green light-emitting devices G, wherein a second sub-line 22b is arranged adjacent to a third data line 23 connected to the green light-emitting device G to reduce the interference of the second data line 22 on other light-emitting devices and improve the display stability.

[0076] Please refer to Table 1, which is a load comparison table of the first data line 21 and the second data line 22 in an embodiment of the present application. The first data line 21 and the second data line 22 are each connected to a corresponding column of green light-emitting devices G, and the two columns of green light-emitting devices G are also adjacent to each other.

[0077]

[0078] It should be noted that the in-plane ratio refers to the ratio of the load of the data line to the load of the total data lines in the total display area. Figure 3 In the vicinity of the first display area AA1, in the second direction F2 (longitudinal direction), the first data line 21 is designed to be concave and convex, and the second sub-line 22b of the second data line 22 is designed to be a straight line.

[0079] As can be seen from Table 1, the second data line 22 adopts the winding method of the connection line 223, which does not cause a large load difference and does not cause obvious display difference. At the same time, it can also improve the transmittance of the first display area AA1.

[0080] Please continue to refer to Figure 3 In some embodiments of the present application, in the display panel 100 viewed from a top perspective, the first display area AA1 has a central axis zz extending along the second direction F2. The farther the connecting line 223 of the second data line 22 is from the central axis zz, the closer it is to the first display area AA1. Two adjacent connecting lines 223 are arranged separately.

[0081] It can be understood that the connecting line 223 is semi-circular or quasi-semi-circular, and multiple connecting lines 223 are arranged in a manner of half a circle around the other half circle in a direction away from the first display area AA1, so that any two connecting lines 223 do not intersect or overlap, thereby avoiding the risk of mutual interference between data signals and improving the stability of the display of the first display area AA1.

[0082] Optionally, in some embodiments of the present application, in a top view of the display panel 100, the further the connecting trace 223 of the second data line 22 is from the central axis zz, the shorter the length. The further the connecting trace 223 of the second data line 22 is from the central axis zz, the longer the total length of the auxiliary portion 24 corresponding to the connecting trace 223 of the second data line 22 is.

[0083] It is understandable that by complementing the lengths of the connecting wires 223 and the auxiliary portion 24 , the wiring area in the unit area of ​​the second display area AA2 is uniform, thereby improving the uniformity of light distribution and further improving the uniformity of display.

[0084] Secondly, in the second direction F2, in the top area a02 of the second display area AA2, which is adjacent to the first display area AA1 and far from the data signal input terminal, the portion of the second data line 22 closer to the central axis zz is located in the center of the top area a02, while the portion of the second data line 22 farther from the central axis zz is located on either side of the top area a02. From the center of the top area a02 toward the sides, the length of the second data line 22 decreases, while the length of the auxiliary portion 24 connected to the second data line 22 increases. This results in a load on the second data line 22 that decreases as it moves farther from the central axis zz, and closer to the load of the first data line 21 and the third data line 23. This results in a load on the second data line 22 decreasing from the center of the top area a02 toward the sides, enabling better display transition and improving display uniformity.

[0085] Optionally, in some embodiments of the present application, in a top-down view of the display panel 100, in the first direction F1, the closer the second sub-line 22b is to the first display area AA1, the shorter the length. In the second direction F2, the closer the first sub-line 22a is to the first display area AA1, the shorter the length, and the closer the third sub-line 22c is to the first display area AA1, the shorter the length.

[0086] In the display panel 100 viewed from above, in the second direction F2, the first auxiliary portion 241 corresponding to the first sub-line 22a closer to the first display area AA1 is longer, and the third auxiliary portion 243 corresponding to the third sub-line 22c closer to the first display area AA1 is longer.

[0087] Optionally, in some embodiments of the present application, the display panel 100 includes a first cathode connection line 31 extending along the first direction F1, and the first cathode connection line 31, the first sub-line 22a, and the third sub-line 22c are arranged in the same layer and spaced apart. In the second display area AA2, the first sub-lines 22a are arranged spaced apart in the extending direction of a portion of the first cathode connection line 31, and the third sub-lines 22c are arranged spaced apart in the extending direction of a portion of the first cathode connection line 31. The portion of the first cathode connection line 31 extends through the entire second display area AA2.

[0088] It will be appreciated that the first cathode connection lines 31 extend along the first direction F1. The first cathode connection lines 31 are configured to electrically connect the cathodes of the light-emitting devices 01. In the second display area AA2, the first cathode connection lines 31 are arranged at intervals along the second direction F2. First sub-lines 22a are arranged at intervals along the extension direction of some of the first cathode connection lines 31, and third sub-lines 22c are arranged at intervals along the extension direction of some of the first cathode connection lines 31. Some of the first cathode connection lines 31 extend through the entire second display area AA2, ensuring that the wiring area within each unit area of ​​the second display area AA2 is uniform, thereby improving display uniformity.

[0089] Optionally, in some embodiments of the present application, the distance between two adjacent first cathode connecting lines 31 is equal to the distance between two adjacent first sub-lines 22a and the distance between two adjacent third sub-lines 22c, so that the wiring formed by the first cathode connecting lines 31, the first sub-lines 22a and the third sub-lines 22c are arranged at equal intervals, thereby improving the wiring positions within each unit area of ​​the second display area AA2 to be consistent, thereby further improving the display uniformity.

[0090] Optionally, in some embodiments of the present application, the display panel 100 includes a second cathode connection line 32 extending along the second direction F2. The second cathode connection line 32 is disposed in a different layer from and electrically connected to the first cathode connection line 31. The second cathode connection line 32 and the second sub-line 22b are disposed in the same layer and spaced apart. The second sub-lines 22b are spaced apart along the extension direction of a portion of the second cathode connection line 32. The portion of the second cathode connection line 32 extends through the entire second display area AA2.

[0091] It will be appreciated that the second cathode connection lines 32 extend along the second direction F2. The second cathode connection lines 32 are configured to electrically connect to the cathodes of the light-emitting devices 01. In the second display area AA2, the second cathode connection lines 32 are arranged at intervals along the first direction F1. Second sub-lines 22b are arranged at intervals along the extension direction of some of the second cathode connection lines 32. Some of the second cathode connection lines 32 extend through the entire second display area AA2, ensuring that the wiring area within each unit area of ​​the second display area AA2 is uniform, thereby improving display uniformity.

[0092] Optionally, the distance between two adjacent second cathode connection lines 32 is equal to the distance between two adjacent second sub-lines 22b, so that the wiring formed by the second cathode connection lines 32 and the second sub-lines 22b is arranged at equal intervals, thereby improving the wiring positions in each unit area of ​​the second display area AA2 to be consistent, further improving the display uniformity.

[0093] In addition, it should be noted that in existing panel technology, the cathode connecting lines are usually designed in a grid shape and set on the entire surface. However, the embodiment of the present application disconnects part of the cathode connecting lines and uses via g1 to connect to form connecting lines 223, without the need to set up additional connecting lines 223, thereby saving wiring space and improving the opening ratio.

[0094] Optionally, in some embodiments of the present application, the second cathode connection line 32 does not extend into the first display area AA1 to improve the light transmittance of the first display area AA1.

[0095] Optionally, in some embodiments of the present application, the first sub-line 22a is connected to the first routing line 221 through a first avoidance line 41, and the first avoidance line 41 includes a first connection end 41a connected to the first routing line 221, and the distance between the first connection end 41a and the adjacent routing line on the same layer is greater than the distance between the first sub-line 22a and the adjacent routing line on the same layer.

[0096] It can be understood that the first avoidance line 41 is set on the same layer as the first sub-line 22a, and the first sub-line 22a transfers the connection between the first sub-line 22a and the first routing line 221 to a position with a larger space through the first avoidance line 41 to meet the setting requirements of the via g1, thereby reducing the risk of short circuit between the first sub-line 22a and other routing lines on the same layer.

[0097] Furthermore, the first avoidance line 41 includes a second connection end 41b connected to the first sub-line 22a. The second connection end 41b is located on the side of the intersection of the first line 221 and the first sub-line 22a, away from the central axis zz. This arrangement allows the first auxiliary portion 241 to be arranged within a limited space and shortens the length of the connecting line 223 to reduce impedance.

[0098] Optionally, in some embodiments of the present application, the third sub-line 22c is connected to the second routing line 222 through a second avoidance line 42, the second avoidance line 42 includes a third connection end 42a connected to the second routing line 222, and the distance between the third connection end 42a and the adjacent routing line on the same layer is greater than the distance between the third sub-line 22c and the adjacent routing line on the same layer.

[0099] It can be understood that the second avoidance line 42 is set on the same layer as the third sub-line 22c, and the third sub-line 22c transfers the connection between the third sub-line 22c and the second routing line 222 to a position with a larger space through the second avoidance line 42 to meet the setting requirements of the via g1, thereby reducing the risk of short circuit between the third sub-line 22c and other routing lines on the same layer.

[0100] In addition, the second avoidance line 42 includes a fourth connection end 42b connected to the third sub-line 22c. The fourth connection end 42b is located on the side of the intersection of the second line 222 and the third sub-line 22c, away from the central axis zz. This arrangement allows the third auxiliary portion 243 to be arranged within a limited space and shortens the length of the connecting line 223 to reduce impedance.

[0101] Please refer to Figure 8 Accordingly, an embodiment of the present application further provides a display device 1000 , comprising the display panel 100 as described in any one of the above embodiments.

[0102] It is understood that the structure of the display panel 100 of the display device 1000 of the embodiment of the present application is similar to or the same as the structure of the display panel 100 of any of the above embodiments. Figures 1 to 7 The explanation will not be repeated here.

[0103] Optionally, the display device 1000 further includes a camera module, which is disposed on the backlight side of the display panel 100 and corresponding to the first display area AA1.

[0104] The camera module includes a transmitter and a receiver. The transmitter is configured to emit infrared light, and the receiver is configured to receive infrared light reflected from a person's face. The transmitter corresponds to a first display area AA1, and the receiver corresponds to another first display area AA1. However, this is not limiting. For example, a single first display area AA1 can provide a light transmission channel for both the transmitter and the receiver. Alternatively, the display panel 100 includes a single first display area AA1, and the camera module is a conventional camera module, such as a single-camera module, a multi-camera module, or an infrared camera module.

[0105] The display panel 100 of the display device 1000 of the embodiment of the present application includes a first data line 21 and a second data line 22. The first data line 21 is arranged in the first display area AA1 and the second display area AA2. The first data line 21 is respectively connected to the first pixel circuit 11 and the second pixel circuit 12. The second data line 22 is arranged in the second display area AA2 and is located outside the first display area AA1. The second data line 22 is connected to the second pixel circuit. The second data line 22 includes a first routing line 221, a connecting routing line 223, and a second routing line 222, which are connected in sequence. The first routing line 221 and the second routing line 222 are each connected to the second pixel circuit 12. At least a portion of the connecting routing line 223 intersects with the first data line 21 and is arranged in a different layer. The first routing line 221 and the second routing line 222 are located on opposite sides of the first display area AA1 and are both separated from the first data line 21.

[0106] The length of the second data line 22 is greater than that of the first data line 21 . The second data line 22 further includes an auxiliary portion 24 , which is connected to the connecting trace 223 .

[0107] It is understood that since the second data line 22 is not connected to the first pixel circuit 11 in the first display area AA1, the second data line 22 is routed around the first display area AA1 via the connecting trace 223, thereby reducing the number of data lines in the first display area AA1 and improving the light transmittance of the first display area AA1. Furthermore, since the second data line 22 is routed in a winding manner, its length is longer than that of the first data line 21. Therefore, an auxiliary portion 24 is used to connect the second data line 22 to reduce the load on the second data line 22, thereby reducing the load difference between the first data line 21 and the second data line 22, thereby improving display uniformity in the first display area AA1.

Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for those skilled in the art, based on the ideas of the present application, there may be changes in the specific implementation methods and application scope.
