Description

Technical Field

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

[0002] Current display panels are evolving towards full-screen designs. In full-screen displays, a transparent area with high light transmittance is needed within the main display area to house structures such as cameras. In this case, the pixel density of the transparent area can be set lower than that of the regular display area, thus reducing occlusion and ensuring light transmittance. However, when the pixel density of the transparent area is lower than that of the regular display area, the number of signal lines required for pixels in the transparent area is less than that required for pixels in the regular display area. When the transparent area is surrounded by the regular display area, if the same signal line on both sides of the transparent area is broken along the direction of the signal lines, only a portion of the signal lines in the regular display area on one side of the transparent area will connect to the pixels in the transparent area. Consequently, the signal lines required by the regular display area on the other side of the transparent area will be unable to provide a signal, reducing the display effect. Alternatively, a transition area can be set between the transparent and regular display areas, with connecting lines running through this transition area to connect the signal lines on both sides of the transparent area. However, this increases the area of ​​the transition area and similarly reduces the display effect. Summary of the Invention

[0003] The present invention provides a display panel and a display device to improve the display effect of the display panel.

[0004] In a first aspect, embodiments of the present invention provide a display panel, including a first display area and a second display area; the light transmittance of the first display area is less than the light transmittance of the second display area; the first display area is at least partially disposed around the second display area.

[0005] The first display area is provided with a first pixel and a first signal line electrically connected to the first pixel, and the second display area is provided with a first conductor; along a first direction, n first signal lines extend through the second display area; on both sides of the second display area, the n first signal lines include a first part and a second part, and the first part of m first signal lines is connected to the second part through the first conductor; wherein, n is an integer greater than 1, and m is an integer greater than or equal to 1 and less than n; the first direction is the column direction of the first pixel.

[0006] Optionally, the first signal line is a data line, and the second display area includes a transparent display area and a transition area, wherein the light transmittance of the transition area is less than that of the transparent display area; the transition area is at least partially disposed around the transparent display area.

[0007] The transparent display area and the transition area are provided with multiple light-emitting device areas, each light-emitting device area including at least two light-emitting devices, the at least two light-emitting devices in the light-emitting device area are arranged along a second direction, and the light-emitting devices in the light-emitting device area are connected by a first transparent wire; the transition area is provided with a pixel driving circuit, the pixel driving circuit is connected to the light-emitting devices through a second transparent wire; the first wire and the first transparent wire are disposed on the same layer; wherein, the second direction is the row direction of the first pixel.

[0008] Optionally, the first wire is disposed between different light-emitting device regions.

[0009] Optionally, the second display area is provided with at least two of the first wires, and the at least two first wires are respectively provided in the transparent display area and the transition area.

[0010] Optionally, k light-emitting devices in the light-emitting device area are arranged along the second direction, and the second display area is provided with n / k first wires; along the first direction, each first wire is connected to a corresponding first signal line.

[0011] Optionally, the first conductor is a freely bending conductor.

[0012] Optionally, the second display area is provided with a light-emitting device and a metal layer, the metal layer being disposed on the side of the light-emitting device away from the light-emitting surface, and the metal layer forming the first conductive line.

[0013] Optionally, the light-emitting device includes an anode; along a third direction, the vertical projection of the anode overlaps with the vertical projection of the first conductor; wherein, the third direction is the thickness direction of the display panel.

[0014] Optionally, the first display area is further provided with a second signal line, and the second display area is further provided with a second conductor; the second signal line is connected to the first pixel; along the second direction, the extension direction of p second signal lines penetrates the second display area, and on both sides of the second display area, the p second signal lines include a third part and a fourth part, and the third part of q second signal lines is connected to the fourth part through the second conductor; wherein, p is an integer greater than 1, and q is an integer greater than or equal to 1 and less than p; the second direction is the row direction of the first pixel.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0026] Figure 1 A schematic diagram of the structure of a display panel provided by the prior art. For example... Figure 1As shown, the display panel includes a conventional display area 101, a transition area 102, and a transparent display area 103. The transition area 102 surrounds the transparent display area 103, and the conventional display area 101 surrounds the transition area 102. Because the conventional display area 101 surrounds the transparent display area 103, the display panel can form an offshore full-screen display panel. The pixel density in the transparent display area 103 is lower than the pixel density in the conventional display area 101; that is, the number of pixels in the transparent display area 103 per unit area is less than the number of pixels in the conventional display area 101. When the transparent display area 103 only has light-emitting devices, and the transition area 102 has a pixel driving circuit to provide driving current to the light-emitting devices in the transparent display area 103, the pixel density of the transparent display area 103 is the number of light-emitting devices per unit area. At this time, the signal lines 104 on both sides of the transparent display area 103 are disconnected along the direction X' of the signal line extension. The display panel also includes a driver chip 105. In the disconnected signal line 104, the portion 104A connected to the driver chip 105 has a driving signal, while the other portion 104B of the signal line 104 does not. When the pixel density in the transparent display area 103 is less than the pixel density in the conventional display area 101, the corresponding transition area 102 has fewer pixel driving circuits. The transition area 102 requires fewer signal lines 104 than the conventional display area 101. This causes a portion of the disconnected signal line 104 located on the side of the transparent display area 103 to wind around to the transition area 102, providing a driving signal to the pixel driving circuit of the transition area 102. This allows the pixel driving circuit to provide driving current to the light-emitting devices in the transparent display area 103. The portion of the signal line 104A located on the side of the transparent display area 103 remains disconnected to avoid increasing the area of ​​the transition area 102. At this time, the signal line 104B, which is disconnected on the other side of the transparent display area 103, cannot receive a driving signal, causing the pixels in that part of the regular display area 101 to fail to emit light normally, thus reducing the display effect of the display panel. Alternatively, a connecting line can be provided in the transition area 102, and the disconnected signal line 104 can be connected through the connecting line in the transition area 102. However, since there are many signal lines 104, the disconnected signal lines 104 will increase the area of ​​the transition area 102 when they are wound through it, which will also reduce the display effect of the display panel. For example, the signal line 104 can be a data line. Figure 2 A partial schematic diagram of a display panel provided for the prior art. (e.g.) Figure 2As shown, the display panel also includes a compensation transition area 106. Along the direction X' extending from the signal lines, the signal lines that are disconnected on both sides of the transparent display area 103 are connected by winding through the compensation transition area 106. This compensation transition area 106 is added in addition to the transition area 102. Typically, the width of the additional compensation transition area 106 in the display panel is 2.5mm, increasing the overall area of ​​the transition area in the display panel, reducing the area of ​​the conventional display area 101, and thus lowering the display effect of the display panel.

[0027] To address the aforementioned technical problems, embodiments of the present invention provide a display panel. Figure 3 This is a schematic diagram of a display panel provided in an embodiment of the present invention. Figure 3 As shown, the display panel includes a first display area 110 and a second display area 120; the light transmittance of the first display area 110 is less than that of the second display area 120; the first display area 110 is at least partially disposed around the second display area 120; the first display area 110 is provided with a first pixel P1 and a first signal line L1 electrically connected to the first pixel P1, and the second display area 120 is provided with a first conductor L2; along the first direction X, n first signal lines L1 extend through the second display area 120; on both sides of the second display area 120, the n first signal lines L1 include a first part L11 and a second part L12, and the first part L11 of m first signal lines L1 is connected to the second part L12 through the first conductor L2; wherein, n is an integer greater than 1, and m is an integer greater than or equal to 1 and less than n; the first direction X is the column direction of the first pixel P1.

[0028] Specifically, the display panel can be a full-screen display panel. The first display area 110 can be the regular display area of ​​the display panel, or the main screen of the display panel. The second display area 120 can be the abnormal display area of ​​the display panel, or the secondary screen of the display panel. The pixel density of the second display area 120 can be set to be smaller than that of the first display area 110 to ensure that the light transmittance of the second display area 120 is greater than that of the first display area 110. This allows a photosensitive element to be placed at a corresponding position in the second display area 120, enabling under-screen light sensing of the display panel and thus achieving full-screen display. For example, the photosensitive element can be a camera, enabling under-screen imaging of the display panel.

[0029] Additionally, the first display area 110 is provided with a plurality of first pixels P1 and a first signal line L1 electrically connected to the first pixels P1. The first pixels P1 can be arranged in an array. The first signal line L1 provides a driving signal for the first pixels P1. The second display area 120 is provided with second pixels P2, and the density of the second pixels P2 is less than the density of the first pixels P1. The number of columns formed by the array of second pixels P2 is less than the number of columns of first pixels P1 in the first display area 110 corresponding to the second display area 120. For example, the first signal line L1 can be a data line used to provide data signals for a column of first pixels P1. In this case, it can be set that along the first direction X, the number of columns formed by the array of second pixels P2 is less than the number of columns of first pixels P1 in the first display area 110 corresponding to the second display area 120. When the first display area 110 is arranged around the second display area 120, the n first signal lines L1 are divided into a first part L11 and a second part L12 at the second display area 120, and the first part L11 and the second part L12 of the same first signal line L1 correspond to each other. The display panel may also include a driving module, which may be located at one end of the first signal line L1, for example, at the end of the first portion L11 away from the second portion L12, and is used to provide a driving signal for the first signal line L1. When the first signal line L1 is divided into the first portion L11 and the second portion L12, the driving signal provided by the driving module can only be provided to the first portion L11, and there is no driving signal for the second portion L12. Figure 3 The example illustrates six first signal lines L1, each comprising a first portion L11 and a second portion L12. The number of n first signal lines L1 is greater than the number of first signal lines L1 required for the second pixel P2. In this case, of the n first signal lines L1, the first portions L11 of nnm first signal lines L1 extend to the second display area 120 and connect to the second pixel P2 in the second display area 120, providing a driving signal for the second pixel P2. The first portions L11 of the other m first signal lines L1 are connected to their corresponding second portions L12 via different first wires L2, providing a driving signal for the second portions L12. This allows the first pixel P1 at the second portion L12 to emit light normally according to the driving signal, ensuring that the first pixels P1 within the first display areas 110 on both sides of the second display area 120 can emit light, improving the display effect of the display panel. When the second display area 120 includes a transition area, the disconnected first signal lines L1 can be wrapped to increase the area of ​​the transition area, ensuring the display effect of the display panel. Figure 3 The example shows that the first portion L11 of the three first signal lines L1 is connected to the corresponding second portion L12 via the first conductor L2.

[0030] It should be noted that the first conductor L2 can be disposed on the same layer as the first signal line L1, in which case the first conductor L2 and the first signal line L1 can make contact to achieve electrical connection. Alternatively, the first conductor L2 can be disposed on a different layer from the first signal line L1, in which case the first conductor L2 can be connected to the first signal line L1 through a via.

[0031] Figure 4 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention. Figure 5 This is a cross-sectional structural diagram of a display panel provided in an embodiment of the present invention. Figure 4 and Figure 5 As shown, the first signal line L1 is a data line, and the second display area 120 includes a transparent display area 121 and a transition area 122. The light transmittance of the transition area 122 is less than that of the transparent display area 121. The transition area 122 is at least partially arranged around the transparent display area 121. The transparent display area 121 and the transition area 122 are provided with a plurality of light-emitting device areas A. Each light-emitting device area A includes at least two light-emitting devices D1. The at least two light-emitting devices D1 in the light-emitting device area A are arranged along the second direction Y, and the light-emitting devices D1 in the light-emitting device area A are connected by a first transparent wire L3. The transition area 122 is provided with a pixel driving circuit 1221, which is connected to the light-emitting devices D1 through a second transparent wire L4. The first wire L2 and the first transparent wire L3 are arranged on the same layer. The second direction Y is the row direction of the first pixel P1.

[0032] Specifically, the transparent display area 121 has a relatively high light transmittance and is used to house the photosensitive element. The second pixel P2 includes a pixel driving circuit and a light-emitting device. The pixel driving circuit has a relatively low light transmittance. Therefore, only the light-emitting device D1 can be placed in the transparent display area 121 to ensure the light transmittance of the transparent display area 121. The transition area 122 can house the pixel driving circuit 1221 and is connected to the light-emitting device D1 in both the transparent display area 121 and the transition area 122 via a second transparent wire L4 to provide driving current to the light-emitting device D1. At this time, the pixel density of the transparent display area 121 and the transition area 122 can be set to be lower than the pixel density of the first display area 110 to ensure that the space for the pixel driving circuit 1221 in the transition area 122 meets the requirements. The display panel includes a substrate, and the light-emitting device D1 is disposed on the array substrate. The light-emitting devices D1 in the light-emitting device area A can be light-emitting devices with the same emission color. After being connected by the first transparent wire L3, the light-emitting devices D1 in the light-emitting device area A can be driven by a single pixel driving circuit, realizing a structure where one pixel driving circuit drives multiple light-emitting devices D1, reducing the number of pixel driving circuits required. Each light-emitting device D1 includes an anode. The first transparent wire L3 is disposed on the side of the anode near the substrate B1, used to connect the anode of the light-emitting devices D1 in the light-emitting device area A, thus connecting different light-emitting devices D1. A second transparent wire L4 can be disposed on the side of the first transparent wire L3 near the substrate B1, and the materials of both the first transparent wire L3 and the second transparent wire L4 have relatively high light transmittance to ensure the light transmittance of the transparent display area 121. When at least two light-emitting devices D1 in the light-emitting device area A are arranged along the second direction Y, the number of first signal lines L1 required along the second direction Y in the light-emitting device area A is less than the number of disconnected first signal lines L1, i.e., less than n. At this point, the first portions L11 of n of the n first signal lines L1 can be extended to the transition area 122 and connected to the pixel driving circuit corresponding to the light-emitting device D1 to provide driving signals for the pixel driving circuit. At least one of the first portions L11 of the remaining m first signal lines L1 is connected to the second portion L12 of the same first signal line L1 through a first conductor L2, so that the driving signal on the first portion L11 is transmitted to the second portion L12 through the first conductor L2. Then, the first pixel P1 connected to the second portion L12 can emit light normally, improving the display effect of the display panel. At the same time, it can avoid increasing the area of ​​the transition area 122 by connecting the first portion L11 of the first signal line L1 to the second portion L12 by winding, thus ensuring the display effect of the display panel.

[0033] When the first signal line L1 is a data line, the first signal line L1 extends along the column direction and the second transparent wire L4 extends along the row direction. By setting the first wire L2 and the first transparent wire L3 to be on the same layer, the short circuit phenomenon caused by the intersection of the first wire L2 and the second transparent wire L4 can be avoided.

[0034] Furthermore, when the first conductive line L2 and the first transparent conductive line L3 are disposed in the same layer, the materials of the first conductive line L2 and the first transparent conductive line L3 can be the same, for example, indium tin oxide (ITO). Forming them in the same process not only avoids the need for additional process steps to form the first conductive line L2, but also ensures the light transmittance of the first conductive line L2, thereby ensuring the light transmittance of the transparent display area 121.

[0035] For example, when two light-emitting devices D1 in the light-emitting device area A are arranged along the second direction Y, and the number of disconnected first signal lines L1 is n, the number of pixel driving circuits corresponding to the light-emitting devices D1 in the light-emitting device area A can be n / 2. In this case, the first part L11 of n / 2 first signal lines L1 extends to the transition area 122 and connects to the pixel driving circuit to provide driving current for the light-emitting devices D1 in the light-emitting device area A. There are n / 2 first conductors L2, and the first part L11 of the remaining n / 2 first signal lines L1 is connected to the corresponding second part L12 through a first conductor L2, which enables the first pixel P1 at the second part L12 to emit light normally, improves the display effect of the display panel, and avoids the winding connection of the first signal lines L1, thus ensuring the display effect of the display panel. For example, among the n first signal lines L1, the first part L11 of the odd-numbered first signal lines L1 extends to the transition area 122 and connects to the pixel driving circuit, and the first part L11 of the even-numbered first signal lines L1 is connected to the corresponding second part L12 through the first conductor L2. Alternatively, among the n first signal lines L1, the first part L11 of the even-numbered first signal line L1 extends to the transition region 122 and is connected to the pixel driving circuit, and the first part L11 of the odd-numbered first signal line L1 is connected to the corresponding second part L12 through the first wire L2.

[0036] Continue to refer to Figure 4 and Figure 5 At least one first wire L2 is disposed between different light-emitting device regions A.

[0037] Specifically, the first transparent wire L3 is used to connect the light-emitting device D1 within the light-emitting device area A, therefore the first transparent wire L3 is disposed within the light-emitting device area A. When the first wire L2 and the first transparent wire L3 are disposed on the same layer, the first wire L2 can be disposed between different light-emitting device areas A, which can avoid short circuit between the first wire L2 and the first transparent wire L3, ensuring the normal display of the display panel.

[0038] It should be noted that, Figure 4 The diagram only illustrates the extension direction of the first conductor L2. In a specific embodiment, the first conductor L2 is disposed outside the light-emitting device region A and does not contact the first transparent conductor L3.

[0039] Optionally, the first conductive line L2 is a freely bendable line. In this case, the first conductive line L2 can bend and extend along the first direction X between different light-emitting device areas A, which can reduce the diffraction of light by the first conductive line L2, thereby ensuring the light-emitting effect of the light-emitting device D1 within the second display area 120. Preferably, the extension shape of the first conductive line L2 is S-shaped, thereby further reducing the diffraction of light by the first conductive line L2.

[0040] It should be noted that the display panel also has an active layer, a metal layer, and an insulating layer on the substrate for forming a driving circuit layer. For example, an active layer is provided on the substrate to form the active region of the transistor in the pixel driving circuit. Then, multiple metal layers are provided on the side of the active layer away from the substrate to form the gate, source, and drain of the transistor, as well as capacitors in the pixel driving circuit. An insulating layer is provided between the multiple metal layers and between the metal layers and the active layer to prevent short circuits between the metal layers or between the metal layers and the active layer.

[0041] Based on the above technical solutions, the second display area is provided with at least two first wires, which are respectively provided in the transparent display area and the transition area.

[0042] Specifically, the transition zone also includes multiple light-emitting device areas to ensure its illumination. The transition zone may also feature a first conductive line to connect the first and second portions of the first signal line within the transition zone. This ensures that the first pixel connected to the second portion of the corresponding first signal line can emit light normally, improving the display panel's performance. Simultaneously, it avoids increasing the transition zone's area by using a winding method to connect the first portion of the first signal line to the second portion, thus maintaining the display panel's display quality. Furthermore, the first conductive line and the first transparent conductive line are placed on the same layer, ensuring the first conductive line's transparency and preventing it from being placed on the same layer as the pixel driving circuit, simplifying the wiring layout of the transition zone.

[0043] Based on the above technical solution, k light-emitting devices D1 in the light-emitting device area A are arranged along the second direction Y, and the second display area 120 is provided with n / k first wires L2; ​​along the first direction X, each first wire L2 is connected to the corresponding first signal line L1.

[0044] Specifically, when k light-emitting devices D1 in the light-emitting device area A are arranged along the second direction Y, i.e., the k light-emitting devices D1 are connected through the first transparent wire L3, then along the second direction Y, the k light-emitting devices D1 are connected to a pixel driving circuit. For each different light-emitting device D1 in the light-emitting device area A, only the first part L11 of one of the k first signal lines L1 needs to extend to the transition area 122 to provide driving current to the k light-emitting devices D1 through the pixel driving circuit. The first parts L11 of the other k-1 first signal lines L1 can be connected to the second parts L12 through the first wire L2. When the density of the light-emitting devices D1 is equal to the pixel density of the first display area 110, and the second display area 120 is provided with n first signal lines L1 including the first part L11 and the second part L12, then a total of n / k first signal lines L1 with their first parts L11 extending to the transition area 122 provide driving current to the light-emitting devices D1 in the light-emitting device area A through the pixel driving circuit. The remaining n / k first signal lines L1, each with its first portion L11 connected to its second portion L12 via a first conductor L2, enable the normal display of the first pixel at the second portion L12 of the first signal line L1. The first signal line L1 corresponding to the first conductor L2 is the one that is collinear with the first conductor L2. When the first signal line L1 is a data line, the n / k first conductors are sequentially arranged in the same column as the n / k first signal lines L1.

[0045] Furthermore, when the first conductive wire and the first transparent conductive wire can be disposed in the same layer, the first conductive wire can be placed between different light-emitting device areas, avoiding short circuits caused by contact between the first conductive wire and the first transparent conductive wire. Optionally, the first conductive wire can be a freely bendable wire, further preventing short circuits between the first conductive wire and the first transparent conductive wire. Moreover, by making the first conductive wire a freely bendable wire, the diffraction effect of the first conductive wire on the light emitted by the light-emitting device can be reduced, thereby ensuring the light-emitting effect of the light-emitting device.

[0046] Figure 6 This is a cross-sectional structural diagram of another display panel provided in an embodiment of the present invention, with reference to... Figure 4 and Figure 6 The second display area 120 is provided with a light-emitting device D1 and a metal layer M1. The metal layer M1 is disposed on the side of the light-emitting device D1 away from the light-emitting surface, and the metal layer M1 forms the first conductive line L2.

[0047] Specifically, the display panel also includes multiple metal layers disposed on the substrate B1 to form pixel driving circuits. The metal layer M1 can be any metal layer in the display panel, avoiding the need for an additional metal layer. The width of the first conductive line L2 is relatively small. When the first conductive line L2 is disposed in the transparent display area 121, it can avoid severely affecting the light transmittance of the transparent display area 121, ensuring that the light transmittance of the transparent display area 121 meets the requirements. For example, a pixel unit includes a red sub-pixel, a green sub-pixel, and a blue sub-pixel. A corresponding light-emitting unit in the second display area 120 is provided with three light-emitting devices D1 emitting different colors, each light-emitting device D1 corresponding to a first conductive line L2. Along the first direction, the width of the three first conductive lines L2 can be 2µm, extending along the gaps between the light-emitting units. At this time, the light transmission loss rate of the three first conductive lines L2 is approximately 1.57%, meaning that the light transmittance of the transparent display area 121 is greater than 98%, ensuring that the transparent display area 121 meets the light transmittance requirements.

[0048] Figure 7 This is a schematic diagram of the structure of a second display area of ​​a display panel provided in an embodiment of the present invention, as shown below. Figure 7 As shown, the light-emitting device D1 includes an anode A1; along the third direction Z, the vertical projection of the anode A1 overlaps with the vertical projection of the first conductor L2; wherein, the third direction Z is the thickness direction of the display panel.

[0049] Specifically, the anode A1 can be a semi-transparent and semi-reflective film layer with relatively low light transmittance to ensure the light-emitting effect of the light-emitting device D1. For example, the material of the anode A1 can include ITO / Ag / ITO. Along the third direction Z, when the vertical projection of the first conductor L2 overlaps with the vertical projection of the anode A1, a portion of the first conductor L2 can reduce the light transmittance of the area overlapping with the anode A1 in the second display area. This reduces the area where the first conductor L2 additionally reduces the light transmittance in the second display area, thus helping to ensure the light transmittance of the second display area.

[0050] Based on the above technical solutions, the first display area is further provided with a second signal line, and the second display area is further provided with a second conductor; the second signal line is connected to the first pixel; along the second direction, the extension direction of p second signal lines runs through the second display area, and on both sides of the second display area, the p second signal lines include a third part and a fourth part, and the third part of q second signal lines is connected to the fourth part through the second conductor; wherein, p is an integer greater than 1, and q is an integer greater than or equal to 1 and less than p; the second direction is the row direction of the first pixel.

[0051] Specifically, when the display panel also includes a second signal line, the first signal line and the second signal line are respectively a data line and a scan line. The first signal line extends along the column direction, and the second signal line extends along the row direction. When the scan drive of the display panel is a single-sided drive, the first display area is arranged around the second display area, such that along the first direction, the second part of the first signal line located on the side of the second display area away from the data drive has no data drive signal, and along the second direction, the fourth part of the second signal line located on the side of the second display area away from the scan drive has no scan drive signal. At this time, at least one first signal line can be configured to have its first part connected to the second part through a first wire to provide a data drive signal to the second part, and at least one second signal line can have its third part connected to the fourth part through a second wire to provide a scan drive signal to the fourth part. This allows the first pixel at any position within the first display area to emit light normally, ensuring the display effect of the display panel.

[0052] This invention also provides a display device. Figure 8 This is a schematic diagram of a display device provided in an embodiment of the present invention. Figure 8 As shown, the display device 20 includes a display panel 21 provided in any embodiment of the present invention.
