Description

Technical Field

[0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background Art

[0002] With the development of display technology, display panels have an increasingly higher screen-to-body ratio. Full-screen displays, with their narrow or even borderless display effects, have attracted widespread attention. Currently, display devices such as mobile phones and tablets often require space on the front for commonly used electronic photosensitive devices such as front cameras, infrared sensors, and fingerprint recognition devices. For example, these photosensitive devices are placed at the top of the front of the display device, forming a non-display area at that location, thereby reducing the device's screen-to-body ratio.

[0003] In the prior art, in order to increase the screen-to-body ratio, a high-light-transmittance area may be provided in the display area of ​​the display panel to accommodate the above-mentioned photosensitive device.

[0004] With the development of full-screen displays, more and more electronic photosensitive devices need to be integrated under the screen. For example, a semi-transparent area is set on the display screen, and the camera is placed below the screen and correspondingly placed in the semi-transparent area. During normal display, the semi-transparent area can play a display role; when taking photos or videos, the camera shoots photos or videos through the semi-transparent area, so that the semi-transparent area can realize the display and shooting functions simultaneously. How to achieve high transmittance of the semi-transparent area while simplifying the production process has become one of the technical problems that need to be solved at this stage. Summary of the Invention

[0005] In view of this, the present invention provides a display panel and a display device, which are beneficial to improving the transmittance of the semi-transparent area, reducing the wiring arrangement density of the semi-transparent area, and reducing the crosstalk between adjacent wirings in the semi-transparent area.

[0006] In a first aspect, the present application provides a display panel comprising a display area and a non-display area, wherein the display area comprises a first display area and at least one second display area, wherein the first display area at least partially surrounds the second display area; and the second display area comprises at least two semi-transparent areas and a spacer area located between two adjacent semi-transparent areas.

[0007] The display area includes a plurality of sub-pixels and a pixel driving circuit electrically connected to the sub-pixels. The pixel driving circuit electrically connected to the sub-pixels in the semi-transparent area is at least partially located in the first display area and the spacer area.

[0008] In a second aspect, the present application provides a display device, including the display panel provided by the present application.

[0009] Compared with the prior art, the display panel and display device provided by the present invention achieve at least the following beneficial effects:

[0010] In the display panel and display device provided by the present invention, a first display area and at least one second display area are provided, the first display area at least partially surrounds the second display area, and the second display area includes at least two semi-transparent areas and a spacer area provided between two adjacent semi-transparent areas. In the display stage, the semi-transparent area and the spacer area in the second display area both play a display function; in the shooting stage, the semi-transparent area in the second display area serves as a light-transmitting area to realize the picture shooting function. The sub-pixels in the first display area and the second display area are both electrically connected to the pixel driving circuit, and the sub-pixels are displayed under the drive of the pixel driving circuit. In particular, the present invention introduces a spacer area between two adjacent semi-transparent areas, and at least part of the pixel driving circuit electrically connected to the sub-pixels in the semi-transparent area is provided in the first display area and the spacer area, thereby avoiding the effect of the pixel driving circuit provided in the semi-transparent area on the transmittance of the semi-transparent area, thereby facilitating the improvement of the transmittance of the semi-transparent area, and thus facilitating the improvement of the shooting quality. In addition, the present invention arranges a portion of the pixel driving circuit electrically connected to the sub-pixels in the semi-transparent area in the first display area and a portion in the spacing area, so that the wiring connecting the pixel driving circuit and the sub-pixels in the semi-transparent area extends from the first display area and the spacing area to the semi-transparent area respectively, which is beneficial to reducing the arrangement density of the wiring, and further beneficial to reducing the crosstalk between adjacent wirings in the semi-transparent area.

[0011] Of course, any product implementing the present invention does not necessarily need to achieve all of the technical effects described above at the same time.

[0033] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0034] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0035] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0036] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0037] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0038] Figure 1 FIG. 1 is a schematic structural diagram of a display panel provided by an embodiment of the present invention. Figure 2 The figure shows a relative position relationship between the pixel driving circuit in the semi-transparent area and the semi-transparent area. Figure 1 and Figure 2 The present invention provides a display panel 100, including a display area AA and a non-display area NA, the display area AA including a first display area AA1 and at least one second display area AA2, the first display area AA1 at least partially surrounding the second display area AA2; the second display area AA2 includes at least two semi-transparent areas 10 and a spacer area 11 located between two adjacent semi-transparent areas 10; the display area AA includes a plurality of sub-pixels and a pixel driving circuit 30 electrically connected to the sub-pixels, and the pixel driving circuit 30 electrically connected to the sub-pixels P in the semi-transparent area 10 is at least partially located in the first display area AA1 and the spacer area 11.

[0039] It should be noted that Figure 1Only the case where the display panel 100 includes one second display area AA2 is shown. In some other embodiments of the present application, two or more second display areas AA2 may be provided on the display panel 100 as needed. The present application does not specifically limit this. The following description will only take the case where the display panel 100 includes one second display area AA2 as an example. When the display panel 100 includes multiple second display areas AA2, the embodiments of the present application may be referred to for execution. Figure 1 Only the situation in which the first display area AA1 completely surrounds the second display area AA2 is shown. In some other embodiments of the present invention, the first display area AA1 may also half surround the second display area AA2. Figure 1 This also only shows a relative position relationship between the first display area AA1 and the second display area AA2 in the display panel 100. In some other embodiments of the present application, the second display area AA2 may also be located at other positions in the display panel 100, which is not specifically limited in the present application. In addition, Figure 1 and Figure 2 The circular shape of the middle semi-permeable area 10 is for illustration only. In some other embodiments of the present application, the semi-permeable area 10 may also be embodied in other shapes such as a rectangle or an ellipse. The size of the semi-permeable area 10 may also be set according to actual needs, and the present application does not impose any specific restrictions on this. Figure 2 The diagram only shows a pixel arrangement of the semi-transparent area 10, which does not represent the actual number and size of pixels. Figure 2 The arrangement of pixels in the spacer area 11 and the first display area AA1 is not shown. The arrangement of pixels in the spacer area 11 and the first display area AA1 may refer to the arrangement of pixels in the prior art, and this application does not make any specific limitation thereto.

[0040] It is understandable that Figure 1 and Figure 2 Only a second display area AA2 including two semi-transparent areas 10 and a spacer area 11 is used as an example for description. In some other embodiments of the present invention, a second display area AA2 may also include three or more semi-transparent areas 10, and a spacer area 11 is provided between any two adjacent semi-transparent areas 10. This embodiment will only be described by taking a second display area AA2 including two semi-transparent areas 10 as an example. When a second display area AA2 includes three or more semi-transparent areas 10, the pixel driving circuit corresponding to the sub-pixel in the semi-transparent area between the two semi-transparent areas along the arrangement direction of the semi-transparent areas may be located in the two spacers on both sides of the semi-transparent area, or in the first display area adjacent to the semi-transparent area. This application does not make any specific limitations on this.

[0041] In addition, this application only takes the example that the shape and area of ​​the semi-transparent areas included in the same second display area are the same. In some other embodiments of the present invention, the shape and area of ​​the semi-transparent areas included in the same second display area may not be exactly the same, and this application does not specifically limit this. For example, see Figure 3 , Figure 3 FIG2 shows another relative position relationship diagram of the pixel driving circuit and the semi-transparent area. In this embodiment, the two semi-transparent areas 10 have different shapes, one of which is triangular and the other is circular. The areas of the two semi-transparent areas are also different. The pixel driving circuit 30 electrically connected to the sub-pixels P in each semi-transparent area is respectively arranged in the first display area AA1 and the spacer area 11. Figure 4 , Figure 4 FIG. 1 shows another relative position relationship diagram between the pixel driving circuit in the semi-transparent area and the semi-transparent area. In this embodiment, the two semi-transparent areas 10 have the same shape but different areas. The pixel driving circuit 30 electrically connected to the sub-pixels P in each semi-transparent area 10 is respectively arranged in the first display area AA1 and the spacer area 11.

[0042] For more details, please see Figures 1 to 4 The display panel 100 provided in an embodiment of the present invention is provided with a first display area AA1 and at least one second display area AA2. The first display area AA1 at least partially surrounds the second display area AA2. The second display area AA2 includes two semi-transparent areas 10 and a spacer area 11 disposed between two adjacent semi-transparent areas 10. During the display phase, the semi-transparent areas 10 and the spacer area 11 in the second display area AA2 both perform display functions. During the capture phase, the semi-transparent areas 10 in the second display area AA2 function as light-transmitting areas, enabling image capture.

[0043] In the present invention, the first display area AA1 and the second display area AA2 are both provided with a plurality of sub-pixels. It should be noted that, in order to clearly reflect the content of the present invention, Figure 2Only some of the sub-pixels in the semi-transparent area 10 are shown, and some of the pixel driving circuits 30 in the spacer area 11 and the first display area AA1 are shown. The sub-pixels in the spacer area 11 and the first display area AA1 are not shown. It can be understood that sub-pixels are provided in both the spacer area 11 and the first display area AA1, and the sub-pixels in the first display area AA1 and the second display area AA2 are electrically connected to the pixel driving circuit 30, and the sub-pixels display under the drive of the pixel driving circuit 30. It should be noted that the pixel driving circuit 30 electrically connected to the sub-pixels can be implemented using a pixel driving circuit in the prior art, such as a 7T1C driving circuit in the prior art, and this application does not specifically limit this. In particular, the present invention introduces a spacer region 11 between two adjacent semi-transparent areas 10 and disposes at least a portion of the pixel driver circuit 30 electrically connected to the sub-pixels in the semi-transparent area 10 in the first display area AA1 and the spacer region 11. This avoids the effect of disposing the pixel driver circuit 30 in the semi-transparent area 10 on the transmittance of the semi-transparent area 10, thereby facilitating improved transmittance of the semi-transparent area 10 and enhancing image quality. Optionally, in the display panel 100 provided by the present invention, no pixel driver circuit 30 is disposed in each semi-transparent area 10. Instead, the corresponding pixel driver circuit 30 is disposed in the first display area AA1 and the spacer region 11, thereby further improving the transmittance of the semi-transparent area 10. Since the pixel driving circuit 30 and the sub-pixels P need to be electrically connected through wiring, an embodiment of the present invention introduces a spacer area 11 between adjacent semi-transparent areas 10, and a portion of the pixel driving circuit 30 electrically connected to the sub-pixels in the semi-transparent area 10 is arranged in the first display area AA1, and a portion is arranged in the spacer area 11, so that the wiring connecting the pixel driving circuit 30 and the sub-pixels P in the semi-transparent area extends from the first display area AA1 and the spacer area 11 to the semi-transparent area 10 respectively, which is beneficial to reducing the arrangement density of the wiring, and further beneficial to reducing the crosstalk between adjacent wirings in the semi-transparent area.

[0044] Furthermore, to achieve display functionality, pixel driver circuits are typically electrically connected to data lines, obtaining data signals via the data lines. The present invention, by placing the pixel area driver circuits corresponding to the sub-pixels in the semi-transparent area within the first display area AA1 and the spacer area 11, helps reduce the risk of data lines electrically connected to the pixel driver circuits from winding, thereby reducing the load on the data lines.

[0045] In the related art, when the pixel driving circuits 30 corresponding to the sub-pixels in the semi-transparent area 10 are all concentrated in the first display area AA1, the leads between the sub-pixels in the semi-transparent area 10 and the pixel driving circuits 30 will be gathered between the first display area AA1 and the semi-transparent area 10. In order to avoid short circuits caused by the aggregation of the leads, these leads need to be set in different film layers; when these leads are set in different film layers, the wiring located in different film layers corresponds to different processes respectively, which will increase the process complexity and is not conducive to cost savings.

[0046] To this end, in an optional embodiment of the present invention, please continue to refer to Figures 2 to 4 Some of the sub-pixels in the semi-transparent area 10 are electrically connected to the pixel driving circuit 30 in the first display area AA1 through the first lead L1, and another part of the sub-pixels in the semi-transparent area 10 are electrically connected to the pixel driving circuit 30 in the spacer area 11 through the second lead L2. The first lead L1 and the second lead L2 are arranged on the same layer.

[0047] Specifically, in an embodiment of the present invention, when the pixel driving circuit 30 electrically connected to the sub-pixels in the semi-transparent area 10 is disposed in the first display area AA1 and the spacer area 11, a portion of the sub-pixels in the semi-transparent area 10 is electrically connected to the pixel driving circuit 30 disposed in the first display area AA1 via the first lead line L1, while another portion of the sub-pixels in the semi-transparent area 10 is electrically connected to the pixel driving circuit 30 disposed in the spacer area 11 via the second lead line L2. In particular, the first lead line L1 and the second lead line L2 are disposed on the same layer. In this case, the first lead line L1 and the second lead line L2 can be fabricated using the same mask and in the same production process. There is no need to introduce separate fabrication processes for the first lead line L1 and the second lead line L2. A single layer of leads can be used to electrically connect the sub-pixels in the semi-transparent area 10 to the corresponding pixel driving circuit 30, thereby reducing the number of process steps and the production time, thereby improving the production efficiency of the display panel 100. Furthermore, this also helps reduce mask mold costs, saving production costs.

[0048] In an optional embodiment of the present invention, Figure 5 The figure shows a connection diagram of the sub-pixel in the semi-transparent area 10 and the first lead L1 and the second lead L2. The line segment of the first lead L1 in the semi-transparent area 10 is an arc, and the line segment of the second lead L2 in the semi-transparent area 10 is an arc.

[0049] Specifically, in this embodiment, when the sub-pixels in the semi-transparent area 10 are connected to the pixel driving circuit 30 in the first display area AA1 or the spacer area 11 via the first lead L1 or the second lead L2, the first lead L1 and the second lead L2 both include line segments located in the semi-transparent area 10 and line segments located in the first display area AA1 or the spacer area 11. The applicant has discovered that when leads are provided in the semi-transparent area 10, gaps between adjacent leads can easily cause light diffraction, which can easily lead to unclear images. Furthermore, when straight boundaries appear in the semi-transparent area 10 (for example, when the leads are straight), a phenomenon of overlapping diffraction will occur, significantly affecting the image quality. In this application, by providing the line segments of the first lead L1 and the second lead L2 in the semi-transparent area 10 as arcs, the degree of diffraction in the semi-transparent area 10 can be greatly reduced, thereby weakening the impact of the diffraction phenomenon on the image. This is beneficial for improving the clarity and quality of the captured image.

[0050] Optionally, in order to further improve the diffraction phenomenon of the semi-transparent area 10, the present invention can also set the shape of the sub-pixel in the semi-transparent area 10 to a shape including an arc, for example Figures 3 to 5 It should be noted that when the display panel 100 of the present invention is an organic light-emitting display panel, the shape of the sub-pixel refers to the shape of the anode corresponding to the sub-pixel. When the display panel 100 of the present invention is a liquid crystal display panel, the shape of the sub-pixel refers to the shape of the opening area.

[0051] In an optional embodiment of the present invention, both the first lead L1 and the second lead L2 are transparent leads. Specifically, in this embodiment of the present invention, the first lead L1 and the second lead L2 are both made of transparent conductive traces, such as materials such as indium tin oxide. This helps reduce the degree of light obstruction caused by the segments of the first lead L1 and the second lead L2 located in the semi-transparent area 10, thereby further improving the transmittance of the semi-transparent area 10 and enhancing the image quality of the display panel 100.

[0052] In an optional embodiment of the present invention, Figure 6 The figure shows a schematic diagram of a pixel arrangement in the normal area 20, the transition area 21 and the second display area AA2 in an embodiment of the present invention. Figure 5 and Figure 6The first display area AA1 includes a regular area 20 and a transition area 21, the transition area 21 is located between the regular area 20 and the second display area AA2, the pixel density of the regular area 20 is greater than the pixel density of the transition area 21, and the pixel density of the transition area 21 is greater than the pixel density of the semi-transparent area 10; the pixel density of the spacer area 11 is greater than the pixel density of the semi-transparent area 10, and the pixel density of the spacer area 11 is greater than or equal to the pixel density of the transition area 21; the pixel driving circuit 30 located in the first display area AA1 and electrically connected to the sub-pixels in the semi-transparent area 10 is located in the transition area 21.

[0053] For more details, please see Figure 5 and Figure 6 In the present application, the first display area AA1 is provided with a regular area 20 and a transition area 21. The transition area 21 is located between the regular area 20 and the second display area AA2. The pixel density of the transition area 21 is lower than that of the regular area 20, and the pixel density of the transition area 21 is higher than that of the semi-transparent area 10. When the pixel driving circuits 30 are fabricated in the regular area 20 and the transition area 21, they are usually fabricated at the same arrangement density. When the pixel density of the transition area 21 is lower than that of the regular area 20, within the same unit area, the number of pixel driving circuits 30 required to drive the sub-pixels in the transition area 21 will be smaller than the number of pixel driving circuits 30 required to drive the sub-pixels in the regular area 20. In this way, there will be more pixel driving circuits in the regular area, and these pixel driving circuits can serve as pixel driving circuits for driving the sub-pixels in the semi-transparent area 10 to emit light. In addition, due to the large difference in pixel density between the semi-transparent area 10 and the regular area 20, the present application sets the pixel density of the sub-pixels in the transition area 21 to be greater than the pixel density of the sub-pixels in the semi-transparent area 10 and less than the pixel density of the regular area 20. The transition area 21 realizes the transition of pixel density between the semi-transparent area 10 and the regular area 20, avoiding the obvious display unevenness between the semi-transparent area 10 and the regular area 20 due to the large difference in pixel density during the display stage. Therefore, the setting method of the pixel density in the transition area 21 is also beneficial to improving the display uniformity of the display panel 100 during the display stage.

[0054] In an optional embodiment of the present invention, Figure 7 1. FIG. 1 is a schematic diagram of another pixel arrangement in the conventional area 20, the transition area 21 and the second display area AA2 in an embodiment of the present invention. In the direction F from the second display area AA2 to the first display area AA1, the pixel density of the transition area 21 increases.

[0055] Specifically, the embodiment of the present invention implements a gradual design for the pixel density of the transition area 21, so that the pixel density of the transition area 21 shows an increasing trend in the direction F from the second display area AA2 to the first display area AA1, that is, from the semi-transparent area 10 to the conventional area 20, the pixel density of the transition area 21 increases, and the pixel density of the portion of the transition area 21 close to the semi-transparent area 10 is close to the pixel density of the semi-transparent area 10, and the pixel density of the portion close to the conventional area 20 is close to the pixel density of the conventional area 20. Therefore, it is beneficial to reduce the display difference between the transition area 21 and the semi-transparent area 10, and it is also beneficial to reduce the display difference between the transition area 21 and the conventional area 20. Therefore, it is more beneficial to improve the display uniformity of the display panel 100 during the display stage.

[0056] In an optional embodiment of the present invention, Figure 8 The figure shows a connection diagram of the sub-pixels in the semi-transparent area 10 and the corresponding pixel driving circuit 30 in the transition area 21. It should be noted that: Figure 8 Only a schematic arrangement of the pixel driving circuit 30 in the transition area 21 is shown, and the sub-pixels in the transition area 21 are not shown. In fact, a plurality of sub-pixels electrically connected to the first pixel driving circuit 31 in a one-to-one correspondence are provided in the transition area 21 to realize the display function of the transition area 21.

[0057] See Figure 8 The pixel driving circuit 30 in the transition area 21 includes a first pixel driving circuit 31 and a second pixel driving circuit 32, wherein the first pixel driving circuit 31 is electrically connected to the sub-pixels in the transition area 21 in a one-to-one correspondence, and the second pixel driving circuit 32 is electrically connected to the sub-pixels in the semi-transparent area 10; the first pixel driving circuits 31 are arranged in an array along the first direction D1 and the second direction D2 in the transition area 21, and the second pixel driving circuit 32 is located between two adjacent first pixel driving circuits 31 along the first direction D1 and / or along the second direction D2, and the first direction D1 and the second direction D2 intersect. It should be noted that in order to clearly distinguish the first pixel driving circuit 31 and the second pixel driving circuit 32, Figure 8The first pixel driving circuit 31 and the second pixel driving circuit 32 are schematically shown in different filling methods. In fact, the first pixel driving circuit 31 and the second pixel driving circuit 32 can be formed using the same structure. When manufacturing pixel driving circuits in the display area, multiple pixel driving circuits arranged in an array are usually manufactured in the entire display area. Since the pixel density in the transition area is lower than that in the conventional area, the number of pixel driving circuits required in the transition area is smaller within the same unit area. That is, a portion of the pixel driving circuits in the transition area 21 can serve as the first pixel driving circuit 31 that drives the sub-pixels in the transition area 21, while another portion of the pixel driving circuits located in the transition area 21 can be electrically connected to the sub-pixels in the semi-transparent area 10 to serve as the second pixel driving circuit 32 that drives the sub-pixels in the semi-transparent area 10.

[0058] Optionally, Figure 9 FIG. 1 is another schematic diagram showing another connection between the sub-pixels in the semi-transparent area 10 and the corresponding pixel driving circuit 30 located in the transition area 21. Figure 9 When the second pixel driving circuit 32 in the transition area 21 is electrically connected to the sub-pixels in the semi-transparent area 10, among the second pixel driving circuits 32 in the transition area 21, the second pixel driving circuit 32 that is closer to the semi-transparent area 10 along the first direction D1 can be electrically connected to the sub-pixels in the semi-transparent area 10 that are farther away from the transition area 21, and the second pixel driving circuit 32 that is farther away from the semi-transparent area 10 can be electrically connected to the sub-pixels in the semi-transparent area 10 that are closer to the transition area 21, thereby helping to reduce the length difference of the first lead L1 connecting each sub-pixel and the second pixel driving circuit 32, avoiding a large load difference due to a large length difference of the first lead L1, and thus helping to improve the display brightness uniformity of the sub-pixels in the semi-transparent area 10, and helping to improve the display effect of the semi-transparent area 10.

[0059] In an optional embodiment of the present invention, Figure 10 The figure shows a connection diagram of the sub-pixels in the semi-transparent area 10 and the corresponding pixel driving circuit 30 located in the spacer area 11. The pixel driving circuit 30 in the spacer area 11 includes a third pixel driving circuit 33 and a fourth pixel driving circuit 34. The third pixel driving circuit 33 is electrically connected to the sub-pixels in the spacer area 11 in a one-to-one correspondence. It should be noted that in order to clearly distinguish the third pixel driving circuit 33 from the fourth pixel driving circuit 34, Figure 10 The third pixel driving circuit 33 and the fourth pixel driving circuit 34 are illustrated with different fillings. In fact, the third pixel driving circuit 33 and the fourth pixel driving circuit 34 can be formed with the same structure.

[0060] See Figure 10The third pixel driving circuits 33 are arranged in an array along the first direction D1 and the second direction D2 in the transition area 21, and the fourth pixel driving circuit 34 is located between two adjacent third pixel driving circuits 33 along the first direction D1 and / or along the second direction D2, and the first direction D1 and the second direction D2 intersect.

[0061] Along the first direction D1, the spacer area 11 is located between two adjacent semi-transparent areas 10; the spacer area 11 includes a first spacer area 111 and a second spacer area 112 arranged along the first direction D1, the first spacer area 111 is adjacent to one of the semi-transparent areas 10, and the second spacer area 112 is adjacent to the other semi-transparent area 10; the fourth pixel driving circuit 34 in the first spacer area 111 is electrically connected to the sub-pixel in the semi-transparent area 10 adjacent to the first spacer area 111, and the fourth pixel driving circuit 34 in the second spacer area 112 is electrically connected to the sub-pixel in the semi-transparent area 10 adjacent to the second spacer area 112.

[0062] For more details, please see Figure 10 Because the spacer 11 is located between two adjacent semi-transparent areas 10, the embodiment of the present invention divides the spacer 11 into a first spacer 111 and a second spacer 112. The first spacer 111 and the second spacer 112 are respectively adjacent to different semi-transparent areas 10. That is, one semi-transparent area 10 is located on the side of the first spacer 111 away from the second spacer 112, and the other semi-transparent area 10 is located on the side of the second spacer 112 away from the first spacer 111. The fourth pixel driving circuit 34 corresponding to the sub-pixels in the semi-transparent area 10 adjacent to the first spacer 111 is disposed in the first spacer 111, and the fourth pixel driving circuit 34 corresponding to the sub-pixels in the semi-transparent area 10 adjacent to the second spacer 112 is disposed in the second spacer 112. In this way, the fourth pixel driving circuit 34 in the spacer 11 is electrically connected to the sub-pixels in the semi-transparent area 10 using a proximity connection method, which helps simplify the wiring process of the display panel 100.

[0063] It should be noted that Figure 10 Only one arrangement of the pixel driving circuit 30 in the spacer 11 is shown, and the sub-pixels in the spacer 11 are not shown. In fact, the spacer 11 is provided with a plurality of sub-pixels electrically connected to the third pixel driving circuit 33 in a one-to-one correspondence, so as to realize the display function of the spacer 11. The third pixel driving circuit 33 and the fourth pixel driving circuit 34 in the spacer 11 are arranged in an array along the first direction D1 and the second direction D2.

[0064] It can be understood that when the fourth pixel driving circuit 34 in the first spacing area 111 is electrically connected to the sub-pixels in the semi-transparent area 10, among the fourth pixel driving circuit 34 in the first spacing area 111, the fourth pixel driving circuit 34 that is closer to the semi-transparent area 10 can be electrically connected to the sub-pixels in the semi-transparent area 10 that are farther away from the first spacing area 111, and the fourth pixel driving circuit 34 that is farther away from the semi-transparent area 10 can be electrically connected to the sub-pixels in the semi-transparent area 10 that are closer to the first spacing area 111. The fourth pixel driving circuit 34 in the second spacing area 112 and the sub-pixels in the semi-transparent area 10 can also adopt a similar design, which is beneficial to reducing the length difference of the second lead L2 connecting each sub-pixel and the fourth pixel area driving circuit, avoiding large load differences due to large length differences of the second lead L2, and thus helping to improve the display brightness uniformity of the sub-pixels in the semi-transparent area 10, and helping to improve the display effect of the semi-transparent area 10.

[0065] It should be noted that Figures 2 to 7 The illustrated embodiment shows a situation where the pixel driving circuit 30 corresponding to the sub-pixel in the semi-transparent area 10 is arranged in the transition area 21 and the spacer area 11 on both sides of the semi-transparent area 10 along the first direction D1. In some other embodiments of the present invention, when the pixel driving circuit 30 connected to the sub-pixel in the semi-transparent area 10 is arranged in the transition area 21, the pixel driving circuit 30 may also be located in the transition area 21 on both sides of the semi-transparent area 10 along the second direction D2, for example, see Figure 11 , Figure 11 FIG. 1 is another schematic diagram showing another connection between the sub-pixels in the semi-transparent area 10 and the corresponding pixel driving circuit 30 in the transition area 21 . Figure 11 The arrangement shown is more conducive to avoiding the aggregation of the first lead L1 connecting the sub-pixels in the semi-transparent area 10 and the pixel driving circuit 30 in the transition area 21. While achieving the same-layer arrangement of the first lead L1 and the second lead L2, it is also conducive to reducing the wiring difficulty of the first lead L1.

[0066] In an optional embodiment of the present invention, Figure 12 The diagram shows a relative position relationship between the semi-permeable area 10, the transition area 21 and the spacer area 11. Figure 12, in the same second display area AA2, the semi-transparent area 10 and the spacer area 11 are arranged along the first direction D1; the first display area AA1 includes a regular area 20 and a transition area 21, and the transition area 21 is located between the regular area 20 and the second display area AA2; the transition area 21 includes at least one first transition area 211 and at least one second transition area 212, at least one first transition area 211 is arranged on at least one side of the second display area AA2 along the second direction D2, and at least one second transition area 212 is arranged on at least one side of the second display area AA2 along the first direction D1, and the first direction D1 and the second direction D2 intersect; the pixel driving circuit 30 located in the first display area AA1 and electrically connected to the sub-pixel in the semi-transparent area 10 is located in the second transition area 212.

[0067] It should be noted that Figure 12 Only the second display area AA2 including two semi-transparent areas 10 and one spacer area 11 is used as an example for explanation. In this example, the transition area 21 includes two first transition areas 211 arranged on both sides of the second display area AA2 along the second direction D2 and two second transition areas 212 arranged on both sides of the second display area AA2 along the first direction D1. It should be noted that sub-pixels are arranged in the first transition area 211 and the second transition area 212. In order to clearly reflect the connection relationship between the sub-pixels in the semi-transparent area 10 and the pixel driving circuit 30, the figure does not reflect the sub-pixels arranged in the first transition area 211 and the second transition area 212. Among them, the pixel driving circuit 30 arranged in the first display area AA1 and electrically connected to the sub-pixels in the semi-transparent area 10 is located in the second transition area 212. Figure 12 From the perspective shown, the pixel driving circuit 30 in the transition area 21 that is electrically connected to the sub-pixels in the semi-transparent area 10 is located in the second transition area 212 on the left or right side of the semi-transparent area 10, that is, located in the second transition area 212 arranged opposite to the spacer area 11. In this way, it is equivalent to arranging the pixel driving circuit 30 connected to the sub-pixels in the semi-transparent area 10 on two opposite sides of the semi-transparent area 10 along the first direction D1. At this time, the first lead L1 and the second lead L2 tend to extend along the first direction D1 as a whole, which is conducive to avoiding the winding phenomenon that may occur when the first lead L1 and the second lead L2 extend along different directions.

[0068] In an optional embodiment of the present invention, Figure 13 The figure shows a wiring diagram of the semi-transparent area 10, the transition area 21 and the spacer area 11. The first transition area 211 includes a plurality of first signal lines 41 extending along the first direction D1 and arranged along the second direction D2. The pixel driving circuit 30 located in the spacer area 11 is electrically connected to the first signal lines 41.

[0069] Specifically, since the spacer 11 is provided with a pixel driving circuit 30 for driving the sub-pixels in the spacer 11 to emit light, and a pixel driving circuit 30 for driving the sub-pixels in the semi-transparent area 10 to emit light, in order to achieve normal operation of these pixel driving circuits 30, the pixel driving circuit 30 needs to be connected to a signal line to achieve signal transmission. The present invention arranges the first signal line 41 connected to the pixel driving circuit 30 in the spacer 11 in the first transition area 211. The first signal line 41 extends along the first direction D1 in the first transition area 211 and is arranged along the second direction D2. In this way, the first signal line 41 does not need to be arranged along the outer periphery of the semi-transparent area 10 to achieve electrical connection with the pixel driving circuit 30 in the spacer 11, but instead extends along the first direction D1 in the first transition area 211. Compared with the form of arranging the first signal line 41 in the spacer 11, this embodiment is equivalent to moving the first signal line 41 in the spacer 11 outward, thereby saving space in the spacer 11 for arranging the pixel driving circuit 30 connected to the sub-pixels in the semi-transparent area 10.

[0070] Optionally, the first signal lines 41 in the embodiment of the present invention may be distributed in two first transition areas 211 that are oppositely arranged along the second direction D2. Figure 13 Under the viewing angle shown, the pixel driving circuit 30 distributed on the upper and lower sides of the semi-transparent area 10 in the spacer area 11 near the first transition area 211 above the spacer area 11 can be electrically connected to the first signal line 41 located above the spacer area 11, and the pixel driving circuit 30 in the spacer area 11 near the first transition area 211 below the spacer area 11 can be electrically connected to the first signal line 41 below the spacer area 11, thereby reducing the connection complexity between the pixel driving circuit 30 in the spacer area 11 and the first signal line 41.

[0071] In an optional embodiment of the present invention, Figure 13 The first signal line 41 in the pixel driver circuit is at least one of a gate line, a light-emission control signal line, and a reset signal line. Specifically, a pixel driver circuit typically includes multiple transistors, and different signals need to be provided to different transistors. For example, a signal controlling the transistor to turn on or off can be provided to the control terminal of the transistor via a gate line; when the transistor functions as a light-emission control switch, a light-emission control signal can be provided to the control terminal of the transistor in question via a light-emission control signal line; when the transistor functions as a reset module, a reset signal can be provided to the transistor in question via a reset signal line, and so on.

[0072] In an optional embodiment of the present invention, please continue to refer to Figure 13The sub-pixels in the spacer area 11 are arranged in an array along the first direction D1 and the second direction D2, and the pixel driving circuit 30 corresponding to the sub-pixels located in the same row is electrically connected to the same first signal line 41 through the same signal lead 40, and the signal lead 40 extends along the second direction D2.

[0073] It should be noted that Figure 13 Only the sub-pixels in the spacer 11 are shown, and the pixel driving circuit in the spacer 11 is not shown. In fact, a plurality of pixel driving circuits 30 are provided in the spacer 11. The arrangement of the pixel driving circuits 30 can be seen in FIG. Figure 12 As shown, each sub-pixel in the spacer 11 is electrically connected to a corresponding pixel driving circuit 30 in the spacer 11. Optionally, the first signal line 41 is electrically connected to the second signal line 42 in the first display area AA1. In this embodiment, the sub-pixels in the spacer 11 are arranged in an array along the first direction D1 and the second direction D2. When the pixel driving circuit 30 is electrically connected to the first signal line 41, some sub-pixel rows in the spacer 11 and some sub-pixel rows in the first display area AA1 are located in the same row. At this time, the pixel driving circuit 30 corresponding to the sub-pixels in the same row in the spacer 11 and the first display area AA1 is electrically connected to the first signal line 41 and the second signal line 42 that are electrically connected to each other. In this way, even if the first signal line 41 is routed above or below the semi-transparent area 10, it can be ensured that the driver chip can still provide signals to the sub-pixels in the same pixel row in the spacer 11 and the first display area AA1 according to the original timing.

[0074] In addition, the sub-pixels located in the same row in the spacing area 11 are electrically connected to the same first signal line 41 through a signal lead 40, and the signal transmitted from the same first signal line 41 will be transmitted to each pixel driving circuit 30 corresponding to the sub-pixels in the same row through a signal lead 40. This is beneficial to reducing the number of signal leads 40 connected between the pixel driving circuit 30 corresponding to the sub-pixels located in the same row and the same first signal line 41, thereby helping to reduce the space occupied by the signal leads 40 in the spacing area 11, and therefore helping to reduce the size of the spacing area 11. The smaller the size of the spacing area 11, the more beneficial it is to improve the overall display uniformity of the display panel 100.

[0075] It should also be noted that the pixel driving circuit 30 corresponding to the sub-pixels in the same row in the spacing area may need to be electrically connected to multiple first signal lines 41 at the same time. Figure 13The diagram shows a situation in which the pixel driving circuits 30 corresponding to the sub-pixels in the same row in the spacing area are respectively connected to the four first signal lines 41, and the description is made only by taking the spacing area 11 including four rows of sub-pixels as an example. In fact, the spacing area 11 may include more rows of sub-pixels, and the present invention does not specifically limit this. The pixel driving circuits 30 corresponding to the sub-pixels in different rows in the spacing area 11 are respectively connected to different first signal lines 41. For the same first signal line 41, it is connected to the pixel driving circuit 30 corresponding to a row of sub-pixels through a signal lead 40 extending along the second direction D2.

[0076] Please continue to see Figure 13 In an optional embodiment of the present invention, in the spacing area 11 , the signal leads 40 are arranged on both sides of the sub-pixel row along the first direction D1 .

[0077] Specifically, in the spacer 13, the pixel driving circuits 30 corresponding to the same row of sub-pixels are electrically connected to a plurality of first signal lines 41 via a plurality of signal leads 40. The number of signal leads 40 corresponds to the number of first signal lines 41. When multiple sub-pixel rows are formed in the spacer 11, the number of corresponding first signal lines 41 and the number of signal leads 40 are both relatively large. In embodiments of the present invention, arranging the signal leads 40 on both sides of the sub-pixel row along the first direction D1 helps avoid the phenomenon of the signal leads 40 being clustered on one side of the sub-pixel row, thereby facilitating the rational use of the spacer 11 and making the spacing of the spacer 11 on both sides along the first direction D1 more uniform.

[0078] In an optional embodiment of the present invention, Figure 14 FIG. 4 is a diagram showing a relative position relationship between the first signal line 41 and the signal lead 40 electrically connected thereto. Figure 14 , the signal lead 40 and the first signal line 41 are arranged in different layers. When the signal lead 40 and the first signal line 41 are arranged in different layers, the signal lead 40 and the first signal line 41 are connected through the via K. The introduction of the signal lead 40 does not occupy the space of the film layer where the signal lead 40 is located, which is conducive to improving the arrangement flexibility of the signal lead 40 and also helps to avoid the phenomenon of the same signal lead 40 being electrically connected to different first signal lines 41, thereby improving the reliability of the electrical connection between the signal lead 40 and the first signal line 41.

[0079] Figure 15 The figure shows another wiring diagram of the semi-transparent area 10, the transition area 21 and the spacer area 11. Along the second direction D2, two first transition areas 211 are respectively provided on both sides of the two semi-transparent areas 10. Optionally, the pixel density in the transition area 211 is the same as that in the semi-transparent area 10. The pixel driving circuit electrically connected to the sub-pixels in the first transition area 211 is located in the spacer area 11 and the first display area. It should be noted that Figure 15 The pixel driving unit connected to the sub-pixels in the semi-transparent area 10 and the first transition area 211 is not shown. The connection relationship can be seen in FIG. Figure 12 .and Figure 13 Compared with the embodiment shown, Figure 15 In the illustrated embodiment, taking the first signal line 41 above the semi-transparent area as an example, the first signal line 41 includes a line segment 411 provided above one of the semi-transparent areas 10 and a line segment 412 provided above the other semi-transparent area 10. The line segment 411 and the line segment 412 are provided in one-to-one correspondence and are electrically connected. The two line segments provided in one-to-one correspondence are electrically connected to the sub-pixels located in the same row in the spacing area 11 through the signal lead 40. In this embodiment, the first signal line 41 is not extended directly from one first transition area 211 to another first transition area 211 along the first direction D1, but is extended in the direction of the sub-pixel P of the spacing area 11 through the signal lead 40, thereby saving a certain amount of space between the two first transition areas 211 arranged along the first direction, so that the sub-pixels in the first transition area 211 are more easily connected to the pixel driving unit in the spacing area 10. It should be noted that in Figure 15 From the perspective shown, the arrangement and connection of the first signal lines 41 below the semi-transparent area 10 can refer to the arrangement and connection of the first signal lines 41 above the semi-transparent area 10, and the present invention will not be repeated here. Figure 15 The connection relationship between the first signal line 41 and the second signal line 42 in the first display area is not shown. The connection relationship between the two can be referred to in Figure 13 .

[0080] Figure 16 In the embodiment shown, the line segments 411 and 412 arranged in one-to-one correspondence in the first signal line 41 are electrically connected and connected to the same pixel row in the spacer 11. In other embodiments of the present invention, the first signal line 41 may also be embodied as Figure 16 The form shown, where Figure 16 FIG. 1 shows another wiring diagram of the semi-transparent area 10, the transition area 21 and the spacer area 11. Figure 16In the illustrated embodiment, two groups of first signal lines 41 are disposed above the semi-transparent region 10. One group of first signal lines 41 is located in the first transition region 211 above one of the semi-transparent regions 10, and the other group of first signal lines 41 is located in the first transition region 211 above the other semi-transparent region 10. One group of first signal lines 41 is used to electrically connect to the sub-pixels in odd-numbered rows in the spacer region 11, and the other group of first signal lines 41 is used to electrically connect to the sub-pixels in even-numbered rows in the spacer region. In this way, while providing signals to each row of sub-pixels in the spacer region, the number of first signal lines 41 in the first transition region 211 is reduced. The connection relationship of the first signal lines 41 located below the semi-transparent region 10 can be referred to the connection relationship of the first signal lines 41 located above the semi-transparent region 10, and the present invention will not be further described here.

[0081] In an optional embodiment of the present invention, Figure 17 Shown is another wiring diagram of the semi-transparent area, transition area and spacer area, see Figure 17 , the sub-pixels located in the same row in the spacer area 11 are arranged in the same row as at least some of the sub-pixels in the semi-transparent area 10; in the spacer area 11, the pixel driving circuit 30 corresponding to the sub-pixels arranged in the same row in the spacer area 11 and the semi-transparent area 10 is electrically connected to the same first signal line 41; the first display area AA1 includes a plurality of second signal lines 42 extending along the first direction D1 and arranged along the second direction D2; at least some of the sub-pixels in the semi-transparent area 10 are arranged in the same row as at least some of the sub-pixels in the first display area AA1, and in the first display area AA1, the pixel driving circuit 30 corresponding to the sub-pixels arranged in the same row in the first display area AA1 and the semi-transparent area 10 is electrically connected to the same second signal line 42.

[0082] Specifically, the present invention arranges pixel driving circuits corresponding to the sub-pixels in the semi-transparent area 10 in the first display area AA1 and the spacer area 11. Some of the sub-pixels in the semi-transparent area 10 are arranged in the same row as some of the sub-pixels in the spacer area 11. The pixel driving circuits 30 corresponding to the sub-pixels arranged in the same row in the semi-transparent area 10 and the spacer area 11 are electrically connected to the same first signal line 41. In addition, the pixel driving circuits 30 corresponding to the sub-pixels in the first display area AA1 are electrically connected to a second signal line 42, which provides the signals required for the operation of these pixel driving circuits. Some of the sub-pixels in the first display area AA1 are arranged in the same row as some of the sub-pixels in the semi-transparent area 10. In the first display area AA1, the pixel driving circuits corresponding to the sub-pixels arranged in the same row in the first display area AA1 and the semi-transparent area 10 are electrically connected to the same second signal line 42. In this way, when providing signals to the sub-pixels in the display area, for example, when providing gate signals, the sub-pixels located in the same row in the first display area AA1, the semi-transparent area 10 and the spacer area 11 can obtain the same gate signal, and the above-mentioned sub-pixels located in the same row will be lit at the same time, avoiding the phenomenon of screen tearing.

[0083] In an alternative embodiment of the present invention, see Figure 16 , one of the first signal lines 41 is electrically connected to one of the second signal lines 42 located on both sides thereof along the first direction D1. In this way, the signals transmitted on the electrically connected first signal line 41 and second signal line 42 are the same, and one of the first signal lines 41 is only electrically connected to one of the second signal lines 42 located on both sides thereof along the first direction D1, so that the signal is only transmitted from the second signal line 42 to the first signal line 41, and then transmitted to the corresponding pixel driving circuit through a signal lead 40. Figure 16 At the viewing angle shown, the first signal lines 41 located above and below the left semi-transparent region 10 are electrically connected to the sub-pixels in odd-numbered rows in the spacer 11, and are also electrically connected to the second signal line 42 on the left side of the semi-transparent region 10. The first signal lines 41 located above and below the right semi-transparent region 10 are electrically connected to the sub-pixels in even-numbered rows in the spacer 11, and are also electrically connected to the second signal line 42 on the right side of the semi-transparent region 10. This ensures that signals such as gate signals are provided to the sub-pixels in the spacer 11 while also reducing the number of first signal lines 41.

[0084] In an alternative embodiment of the present invention, see Figure 18 , Figure 18 The diagram shows an arrangement diagram of the second transition area 212, the semi-permeable area 10 and the spacer area 11. Figure 18The second transition area 212, the semi-transparent area 10 and the spacer area 11 are arranged along the first direction D1, the semi-transparent area 10 includes a first semi-transparent area 101 and a second semi-transparent area 102 arranged along the first direction D1, along the first direction D1, the first semi-transparent area 101 is located between the second transition area 212 and the second semi-transparent area 102, and the second semi-transparent area 102 is located between the first semi-transparent area 101 and the spacer area 11; the sub-pixels in the first semi-transparent area 101 are electrically connected to the pixel driving circuit 30 in the second transition area 212, and the sub-pixels in the second semi-transparent area 102 are electrically connected to the pixel driving circuit 30 in the spacer area 11.

[0085] For more details, please see Figure 18 In the embodiment of the present invention, the semi-transparent area 10 is divided into a first semi-transparent area 101 and a second semi-transparent area 102 along a first direction D1. The first semi-transparent area 101 is located on a side of the second semi-transparent area 102 near the second transition area 212, and the second semi-transparent area 102 is located on a side of the first semi-transparent area 101 near the spacer area 11. When electrically connecting the sub-pixels in the semi-transparent area 10 to the pixel driving circuit 30 in the second transition area 212 or the spacer area 11, the sub-pixels in the first semi-transparent area 101 adjacent to the second transition area 212 are electrically connected to the pixel driving circuit 30 in the second transition area 212, and the sub-pixels in the second semi-transparent area 102 adjacent to the spacer area 11 are electrically connected to the pixel driving circuit 30 in the spacer area 11. In this way, the electrical connection between the sub-pixels in the semi-transparent area 10 and the pixel driving circuit 30 outside the semi-transparent area 10 is achieved by using a proximity connection method, which helps to simplify wiring complexity and improve the production efficiency of the display panel 100.

[0086] Based on the same inventive concept, the present application also provides a display device, Figure 19 FIG2 is a schematic diagram of a display device provided in an embodiment of the present application, see FIG2. Figure 19 The display device 200 includes the display panel 100 and the camera 201 provided in any of the above embodiments of the present application; wherein the orthographic projection of the camera 201 on the light-emitting surface of the display panel 100 is located in the second display area AA2. It should be noted that the embodiments of the display device 200 provided in the embodiments of the present application can refer to the above embodiments of the display panel 100, and the repeated parts will not be repeated. The display device 200 provided in the present application can be: a mobile phone, a tablet computer, a television, a monitor, a laptop computer, a digital photo frame, a navigator, or any other product or component with real-world functions.

[0087] In an optional embodiment of the present invention, in one of the second display areas AA2 , one camera corresponds to two of the semi-transparent areas 10 , or two of the semi-transparent areas 10 correspond to two cameras respectively.

[0088] Specifically, in the display device provided by the embodiment of the present invention, only one camera can be set in the area corresponding to the same second display area AA2, that is, a single camera is adopted. In this case, one camera corresponds to two semi-transparent areas 10. In some other embodiments of the present invention, two cameras can also be set in the area corresponding to the same second display area AA2, that is, a dual-camera setting method is adopted. In this case, the cameras are set in a one-to-one correspondence with the semi-transparent areas 10. An interval area is introduced between the two semi-transparent areas 10, and the pixel driving circuits corresponding to the sub-pixels in the semi-transparent area 10 are set in the interval area and the first display area AA1, thereby avoiding the phenomenon that the pixel driving circuits 30 corresponding to the sub-pixels in the semi-transparent area 10 are concentrated in the interval area 11. Therefore, it is beneficial to simplify the manufacturing process of the pixel driving circuit 30 electrically connected to the sub-pixels in the semi-transparent area 10, and improve the production efficiency of the display panel 100 and the display device.

[0089] In summary, the display panel and display device provided by the present invention achieve at least the following beneficial effects:

[0090] In the display panel and display device provided by the present invention, a first display area and at least one second display area are provided, the first display area at least partially surrounds the second display area, and the second display area includes at least two semi-transparent areas and a spacer area provided between two adjacent semi-transparent areas. In the display stage, the semi-transparent area and the spacer area in the second display area both play a display function; in the shooting stage, the semi-transparent area in the second display area serves as a light-transmitting area to realize the picture shooting function. The sub-pixels in the first display area and the second display area are both electrically connected to the pixel driving circuit, and the sub-pixels are displayed under the drive of the pixel driving circuit. In particular, the present invention introduces a spacer area between two adjacent semi-transparent areas, and at least part of the pixel driving circuit electrically connected to the sub-pixels in the semi-transparent area is provided in the first display area and the spacer area, thereby avoiding the effect of the pixel driving circuit provided in the semi-transparent area on the transmittance of the semi-transparent area, thereby facilitating the improvement of the transmittance of the semi-transparent area, and thus facilitating the improvement of the shooting quality. In addition, the present invention arranges a portion of the pixel driving circuit electrically connected to the sub-pixels in the semi-transparent area in the first display area and a portion in the spacing area, so that the wiring connecting the pixel driving circuit and the sub-pixels in the semi-transparent area extends from the first display area and the spacing area to the semi-transparent area respectively, which is beneficial to reducing the arrangement density of the wiring, and further beneficial to reducing the crosstalk between adjacent wirings in the semi-transparent area.
