Description

[Technical field]

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

[0002] Currently, the narrow border design of display panels is a development trend in the existing display field. However, due to the horizontal width required by functional circuits, wiring and other structures in the left and right borders, it is difficult to further narrow the border of the display panel, thus restricting the development of narrow borders or even borderless display panels. [Summary of the invention]

[0003] In view of this, an embodiment of the present invention provides a display panel and a display device, which are used to narrow the border width of the display panel and optimize the narrow border design of the display panel.

[0004] In one aspect, an embodiment of the present invention provides a display panel, including:

[0005] A display area and a non-display area, the non-display area includes a first area and a bending area, the bending area is located between the first area and the display area, and the first area is located on the backlight side of the display panel;

[0006] A pixel circuit, located in the display area;

[0007] A driving signal line electrically connected to the pixel circuit, the driving signal line being located in the display area and extending along a first direction;

[0008] A shift register electrically connected to the driving signal line, at least a portion of the shift register is located in the first area.

[0009] On the other hand, an embodiment of the present invention provides a display device, including the above-mentioned display panel.

[0010] One of the above technical solutions has the following beneficial effects:

[0011] In related designs, the shift register is generally set in the left and right frames of the display panel (the left and right frames are located on both sides of the display area in the first direction). In this way, firstly, the shift register itself needs to occupy a larger frame width in the left and right frames, and secondly, the clock signal line, frame start signal line and other wiring lines connected between the driver chip and the shift register also need to occupy a certain space in the left and right frames and corner frames, resulting in a larger width of the left and right frames and corner frames of the display panel.

[0012] In the embodiment of the present invention, at least part of the shift register is set in the first area of ​​the non-display area 2. It can be understood that in the process of the display panel, the first area will be bent to the backlight side of the display panel along with the bending area, so the first area does not occupy the visible lower border width on the front of the display panel. Therefore, when at least part of the shift register is located in the first area, it can not only effectively reduce the number of shift registers required to be set in the left and right borders, and reduce the number of connecting lines extending between the shift register and the driver chip in the left and right borders and the corner borders, but also will not affect the visible lower border width on the front of the display panel, thereby facilitating the realization of a narrow border design for the display panel.

[0013] In addition, under the premise of not changing the width of the visible lower border on the front of the display panel, the embodiment of the present invention can further increase the width of the first area in the second direction to provide a larger setting space for the shift register, thereby accommodating more shift registers, and then all the shift registers can be set in the first area to further narrow the border width of the display panel.

[0032] In order to better understand the technical solution of the present invention, the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] It should be clear that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0035] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0036] An embodiment of the present invention provides a display panel, such as Figure 1 to Figure 3 As shown, Figure 1 A top view of a display panel provided by an embodiment of the present invention, Figure 2 A cross-sectional schematic diagram of a display panel provided by an embodiment of the present invention, Figure 3 A top view of the bending area in the display panel provided in an embodiment of the present invention is in an unbent state, the display panel includes a display area 1 and a non-display area 2, wherein the non-display area 2 includes a first area 3 and a bending area 4, the bending area 4 is located between the first area 3 and the display area 1, and the first area 3 is located on the backlight side of the display panel.

[0037] The display panel further includes a pixel circuit 5, a driving signal line 6 and a shift register 7. The pixel circuit 5 is located in the display area 1; the driving signal line 6 is electrically connected to the pixel circuit 5, the driving signal line 6 is located in the display area 1 and extends along the first direction x; the shift register 7 is electrically connected to the driving signal line 6, and at least part of the shift register 7 is located in the first area 3.

[0038] It should be noted that the shift register 7 includes a plurality of shift units 8 arranged in cascade, and a first-stage shift unit 8 can be electrically connected to at least one drive signal line 6, and the shift unit 8 is used to provide a drive signal to the drive signal line 6 electrically connected thereto, so as to further transmit the drive signal to the pixel circuit 5 using the drive signal line 6, thereby controlling the pixel circuit 5 to perform a reset operation, a charging operation, and a light emission control operation, etc. In the drawings provided in the embodiments of the present invention, the first-stage shift unit 8 is electrically connected to a drive signal line 6 as an example for illustration.

[0039] In related designs, the shift register is generally set in the left and right frames of the display panel (the left and right frames are located on both sides of the display area 1 in the first direction x). In this way, firstly, the shift register itself needs to occupy a larger frame width in the left and right frames, and secondly, the clock signal line, frame start signal line and other wiring lines connected between the driver chip and the shift register also need to occupy a certain space in the left and right frames and corner frames, resulting in a larger width of the left and right frames and corner frames of the display panel.

[0040] In the embodiment of the present invention, at least part of the shift register 7 is set in the first area 3 of the non-display area 2. It can be understood that in the process of the display panel, the first area 3 will be bent to the backlight side of the display panel along with the bending area 4, so the first area 3 will not occupy the visible lower frame width on the front of the display panel. Therefore, when at least part of the shift register 7 is located in the first area 3, it can not only effectively reduce the number of shift registers 7 required to be set in the left and right frames, and reduce the number of connecting lines extending between the shift register 7 and the driver chip in the left and right frames and corner frames, but also will not affect the visible lower frame width on the front of the display panel, thereby facilitating the realization of a narrow frame design for the display panel.

[0041] In addition, under the premise of not changing the width of the visible lower border on the front side of the display panel, the embodiment of the present invention can further increase the width of the first area 3 in the second direction y to provide a larger setting space for the shift register 7, thereby accommodating more shift registers 7, and then all the shift registers 7 can be set in the first area 3 to further narrow the border width of the display panel.

[0042] In one possible implementation, see again Figure 2 and Figure 3 The first region 3 includes a first sub-region 9 and a second sub-region 10 . The first sub-region 9 is located between the bending region 4 and the second sub-region 10 . The second sub-region 10 is used to bind the driver chip. At least part of the shift register 7 is located in the first sub-region 9 .

[0043] Specifically, a plurality of binding pins are provided in the second sub-area 10 , and the binding pins are electrically connected to the pins of the driving chip to achieve binding of the driving chip with the display panel, and then the driving chip is used to provide the signal lines in the display panel with the signals required for display.

[0044] By setting at least part of the shift register 7 in the first sub-area 9, the shift register 7 in the first area 3 can be located on the side of the second sub-area 10 close to the display area 1. At this time, the shift register 7 is closer to the display area 1. When the drive signal line 6 in the display area 1 is led to the shift register 7 through the connecting lead, the connecting lead does not need to extend to the binding pin of the second sub-area 10, thereby avoiding the risk of short circuit between the connecting lead and the binding pin, and improving the binding reliability of the driver chip. Moreover, by adopting the above-mentioned setting method, after the driver chip is bound to the display panel, the driver chip is closer to the outer edge of the display panel, which also helps the subsequent connection between the binding chip and the motherboard.

[0045] In one possible implementation, see again Figure 3 The display panel further includes a connecting line 11, which is electrically connected to the driving signal line 6 and the shift register 7 respectively. The connecting line 11 is located in the display area 1 and extends along the second direction y, and the second direction y intersects with the first direction x.

[0046] In the above arrangement, the drive signal line 6 is connected to the shift register 7 through the connecting line 11 extending in the display area 1. This part of the connecting line 11 does not occupy the space of the left and right frames, so it can further reduce the horizontal line width required for the routing in the left and right frames, which helps to further optimize the narrow frame design of the display panel. In addition, the drive signal line 6 and the connecting line 11 are arranged horizontally and vertically, and the drive signal line 6 and the connecting line 11 only need to be connected through a via, so the connection method is simpler and the connection reliability is also higher.

[0047] In a possible implementation, Figure 4 As shown, Figure 4 Another top view of the bending area 4 in the display panel provided by the embodiment of the present invention in the unbent state, the display area 1 also includes a light-transmitting hole 12, part of the driving signal line 6 is disconnected and arranged on both sides of the light-transmitting hole 12 in the first direction x, and part of the driving signal line 6 includes a first line segment 13 and a second line segment 14, and the first line segment 13 and the second line segment 14 are respectively located on both sides of the light-transmitting hole 12 in the first direction x. The first line segment 13 and the second line segment 14 are respectively electrically connected to the shift register 7 through the connecting line 11.

[0048] At this time, the first line segment 13 and the second line segment 14 cut off on both sides of the light-transmitting hole 12 are respectively led to the shift register 7 through a connecting line 11, and even if the shift register 7 adopts a single-sided drive, it can still ensure that there is signal transmission on the first line segment 13 and the second line segment 14. In this way, the first line segment 13 and the second line segment 14 no longer need to be wound in the frame 40 around the light-transmitting hole 12 to connect with each other, so the frame width around the light-transmitting hole 12 can also be reduced, thereby effectively optimizing the full-screen display effect of the display panel.

[0049] It should be noted that the connecting line 11 includes a first end and a second end. In an embodiment of the present invention, for at least a portion of the connecting lines 11, the first ends thereof are aligned and the second ends thereof are also aligned, so that the extension lengths of these portions of the connecting lines 11 are the same and the loads are relatively uniform, thereby making the voltage drop of the driving signal transmitted on these portions of the connecting lines 11 tend to be consistent.

[0050] In a possible implementation, Figure 5 As shown, Figure 5 A schematic diagram of the structure of the connection line 11 provided in an embodiment of the present invention, the connection line 11 includes a first connection line 15 and a second connection line 16 arranged in different layers, and the first connection line 15 and the second connection line 16 overlap in a direction perpendicular to the plane where the display panel is located.

[0051] The number of driving signal lines 6 in the display panel is large, so the number of connecting lines 11 required to be set is also large. Figure 4 When the first line segment 13 and the second line segment 14 cut off on both sides of the light-transmitting hole 12 are electrically connected to the shift register 7 through the connecting wires 11, more connecting wires 11 need to be arranged in the display area 1. In this regard, the embodiment of the present invention performs double-layer wiring on the connecting wires 11 and allows the two layers of connecting wires 11 to overlap each other, which can not only reduce the lateral width required for the connecting wires 11 as a whole, but also allow the first connecting wires 15 and the second connecting wires 16 to have larger intervals, thereby avoiding the problem of signal interference caused by overly dense wiring.

[0052] Furthermore, if Figure 6 and Figure 7 As shown, Figure 6 A schematic diagram of a partial structure of a display panel provided by an embodiment of the present invention, Figure 7 for Figure 6 In a cross-sectional view along the A1-A2 direction, the driving signal line 6 includes a first type of driving signal line 17 and a second type of driving signal line 18 arranged in different layers. Among them, the first connecting line 15 is located on the side of the first type of driving signal line 17 facing away from the second type of driving signal line 18, and the first connecting line 15 is electrically connected to the first type of driving signal line 17, and the second connecting line 16 is located on the side of the second type of driving signal line 18 facing away from the first type of driving signal line 17, and the second connecting line 16 is electrically connected to the second type of driving signal line 18.

[0053] Among them, the first type of driving signal line 17 may include a scanning signal line Scan, which is used to transmit a scanning signal to the pixel circuit 5 to control the pixel circuit 5 to perform a reset operation and a charging operation; the second type of driving signal line 18 may include a light-emitting control signal line Emit, which is used to transmit a light-emitting control signal to the pixel circuit 5 to control the pixel circuit 5 to perform a light-emitting control operation.

[0054] It can be understood that the display panel also includes a data line Data electrically connected to the pixel circuit 5, and the data line Data is located in the display area 1 and extends along the second direction y. In one configuration, the first connection line 15 is located on one side of the substrate 19, the scan signal line Scan is located on the side of the first connection line 15 away from the substrate 19, the light control signal line Emit is located on the side of the first type of drive signal line 17 away from the substrate 19, the data line Data is located on the side of the light control signal line Emit away from the substrate 19, and the second connection line 16 is located on the side of the data line Data away from the substrate 19. Insulating layers 20 are also provided respectively between the substrate 19 and the film layer where the first connection line 15 is located, between the film layer where the first connection line 15 is located and the film layer where the scan signal line Scan is located, between the film layer where the scan signal line Scan is located and the film layer where the light control signal line Emit is located, between the film layer where the light control signal line Emit is located and the film layer where the data line Data is located, and between the film layer where the data line Data is located and the film layer where the second connection line 16 is located.

[0055] Generally, the wiring in the same film layer is usually formed of the same metal material. When the drive signal line 6 includes two types of drive signal lines 6, namely, a first type of drive signal line 17 and a second type of drive signal line 18, by connecting the first type of drive signal line 17 to the first connecting line 15 of the same layer, and connecting the second type of drive signal line 18 to the second connecting line 16 of the same layer, the load of the part of the connecting line 11 electrically connected to the first type of drive signal line 17 tends to be consistent, and the load of the part of the connecting line 11 electrically connected to the second type of drive signal line 18 tends to be consistent, thereby improving the consistency of the signals transmitted by different first type drive signal lines 17 and improving the consistency of the signals transmitted on different second type drive signal lines 18.

[0056] Moreover, compared with the second type driving signal line 18, the first type driving signal line 17 is closer to the first connecting line 15, so selecting the first type driving signal line 17 to be electrically connected to the first connecting line 15 can also improve the connection reliability between the two.

[0057] In a possible implementation, Figure 8 As shown, Figure 8A schematic diagram of the film layer position of the connecting wire 11 provided in an embodiment of the present invention, the display panel further includes a substrate 19, a semiconductor layer 21 located on one side of the substrate 19, and a shielding metal layer 22 located between the semiconductor layer 21 and the substrate 19. Among them, at least part of the connecting wire 11 and the shielding metal layer 22 are arranged in the same layer.

[0058] It can be understood that the pixel circuit 5 includes a plurality of transistors 23, and the transistor 23 includes an active layer p, a gate g, a first electrode s, and a second electrode d, wherein the active layer p is located on the semiconductor layer 21. In a direction perpendicular to the plane where the substrate 19 is located, the shielding metal layer 22 can overlap with the active layer p of the transistor 23 to prevent the external ambient light from irradiating the channel of the active layer p and affecting the carrier mobility in the active layer p, thereby improving the reliability of the working state of the transistor 23.

[0059] In the embodiment of the present invention, at least part of the connecting wires 11 are arranged in the same layer as the shielding metal layer 22, so that the connecting wires 11 and the shielding metal layer 22 can be formed by the same patterning process, thereby simplifying the manufacturing process. Moreover, the connecting wires 11 are equivalent to the metal routing wires at the bottom layer, so the connecting wires 11 will not occupy the arrangement space of other signal wires, and can also reduce the mutual interference with other signal wires.

[0060] In a possible implementation, Fig. 9 As shown, Fig. 9 Another schematic diagram of the film layer position of the connection line 11 provided in an embodiment of the present invention, the display panel further includes a power signal line PVDD electrically connected to the pixel circuit 5, the power signal line PVDD is located in the display area 1 and extends along the second direction y. In the direction perpendicular to the plane where the display panel is located, at least part of the connection line 11 overlaps with the power signal line PVDD.

[0061] On the one hand, when the connection line 11 overlaps with the original signal line in the display panel, the external ambient light is incident on the position of the connection line 11, which can reduce the additional impact of the connection line 11 on the reflection of the ambient light, thereby weakening the impact of the connection line 11 on the reflection uniformity of the display panel. On the other hand, the power signal line PVDD is used to transmit a constant voltage signal without voltage jumps. Compared with overlapping the connection line 11 with the data line Data, overlapping the connection line 11 with the power signal line PVDD can also reduce the mutual interference between the connection line 11 and the signal line in the panel.

[0062] In a possible implementation, Fig.10 As shown, Fig.10Another top view of the bending area 4 in the display panel provided in an embodiment of the present invention is in an unbent state, wherein the connecting lines 11 are arranged in the same layer, and the connecting lines 11 are arranged at equal intervals in the first direction x to improve the uniformity of the arrangement of the connecting lines 11 and avoid the connection lines 11 being arranged too densely in a local area and causing interference to other signal lines.

[0063] In one possible implementation, see again Figure 1 and Figure 3 The shift register 7 includes a plurality of shift units 8 arranged in cascade, and the plurality of shift units 8 are arranged along a first direction x in the first region 3 .

[0064] When the connecting line 11 extends to the lower edge of the display area 1, it will be further extended to the first area 3 through the bending area 4 through the fan-out line 24 and connected to the shift unit 8. When multiple shift units 8 in the same shift register 7 are arranged horizontally, the extension length of the fan-out line 24 corresponding to each shift unit 8 can be shortened and the wiring method of the fan-out line 24 can be simplified.

[0065] In a possible implementation, Fig.11 and Fig.12 As shown, Fig.11 Another top view of the bending area 4 in the display panel provided by the embodiment of the present invention in an unbent state, Fig.12 This is another top view of the bending area 4 in the display panel provided by the embodiment of the present invention in the unbent state, and the drive signal line 6 includes a first type of drive signal line 17 and a second type of drive signal line 18. As mentioned above, the first type of drive signal line 17 may include a scan signal line Scan, which is used to drive the pixel circuit 5 to perform a reset operation and a charging operation, and the second type of drive signal line 18 may include a light emitting control signal line Emit, which is used to drive the pixel circuit 5 to perform a light emitting control operation.

[0066] The shift register 7 includes a first shift register 25 electrically connected to the first type of drive signal line 17 and a second shift register 26 electrically connected to the second type of drive signal line 18, wherein the first shift register 25 and / or the second shift register 26 are located in the first area 3 to release a portion of space on the left and right borders of the display panel, which helps to narrow the width of the left and right borders of the display panel.

[0067] In one configuration, see Fig.11, the first shift register 25 is located in the first area 3, the second shift register 26 is driven on both sides, and the second shift register 26 is located on both sides of the display area 1 in the first direction x. At this time, compared with setting the first shift register 25 and the second shift register 26 in the left and right frames, the left frame or the right frame of the display panel can be reduced by more than 0.2mm. Alternatively, in another setting mode, the first shift register 25 and the second shift register 26 are both located in the first area 3. At this time, compared with setting the first shift register 25 and the second shift register 26 in the left and right frames, the left frame and the right frame of the display panel can each be reduced by about 0.4mm.

[0068] Further, see again Fig.12 The first shift register 25 and the second shift register 26 are located in the first area 3, and the first shift register 25 and the second shift register 26 are arranged along the second direction y, and the second direction y intersects with the first direction x.

[0069] When the first shift register 25 and the second shift register 26 are both located in the first area 3, the number of shift units 8 that need to be accommodated in the first area 3 will be relatively large. As mentioned above, since the first area 3 will bend to the backlight side of the display panel along the bending area 4, the first area 3 will not occupy the visible lower border width on the front of the display panel. To this end, by arranging the first shift register 25 and the second shift register 26 along the second direction y, a larger setting space can be provided for the two by increasing the width of the first area 3 in the second direction y, thereby optimizing the arrangement of the first shift register 25 and the second shift register 26, and even if the width of the first area 3 in the second direction y is set larger, it will not affect the visible lower border width on the front of the display panel.

[0070] In a possible implementation, Figure 13 to Figure 15 As shown, Fig.13 Another top view of a display panel provided by an embodiment of the present invention, Fig.14 Another cross-sectional schematic diagram of a display panel provided by an embodiment of the present invention, Fig.15 Another top view of the bending area 4 in the display panel provided in the embodiment of the present invention in the unbent state, the non-display area 2 includes a first non-display area 27 and a second non-display area 28, the first non-display area 27 and the second non-display area 28 are respectively located on both sides of the display area 1 in the second direction y, the first non-display area 27 and the second non-display area 28 both include a first area 3 and a bending area 4, and the second direction y intersects with the first direction x. Part of the shift register 7 is located in the first non-display area 27, and part of the shift register 7 is located in the first area 3 of the second non-display area 28. Exemplarily, the first shift register 25 is located in the first non-display area 27, and the second shift register 26 is located in the second non-display area 28.

[0071] This setting method also sets the first area 3 and the bending area 4 on the upper frame of the display panel, so that at least two shift registers 7 can be dispersedly set in the first area 3 of the upper and lower frames, avoiding a large number of shift registers 7 required to be set in the first area 3 of the lower frame, which helps to optimize the circuit layout and layout design of the first area 3 of the lower frame.

[0072] In a possible implementation, Fig.16 As shown, Fig.16 Another top view of the bending area 4 in the display panel provided in an embodiment of the present invention in an unbent state, the non-display area 2 includes a first non-display area 27 and a second non-display area 28, the first non-display area 27 and the second non-display area 28 are respectively located on both sides of the display area 1 in the second direction y, the first non-display area 27 and the second non-display area 28 both include a first area 3 and a bending area 4, and the second direction y intersects with the first direction x.

[0073] The display area 1 includes a first display area 29 and a second display area 30 . The first display area 29 is located on a side of the second display area 30 close to the first non-display area 27 .

[0074] The shift register 7 includes a plurality of cascaded shift units 8, the shift unit 8 including a first shift unit 31 and a second shift unit 32; wherein the first shift unit 31 is located in the first non-display area 27, and the first shift unit 31 is electrically connected to the drive signal line 6 in the first display area 29, and the second shift unit 32 is located in the second non-display area 28, and the second shift unit 32 is electrically connected to the drive signal line 6 in the second display area 30.

[0075] If the number of driving signal lines 6 is large, the number of shift units 8 required to be set in the shift register 7 is also correspondingly large. Due to the lateral width of the first area 3 in the first direction x, it may be difficult to arrange multiple shift units 8 horizontally.
