Detailed Implementation

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods and means well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0031] Figure 1 The diagram shown is a structural schematic of a display panel provided in an exemplary embodiment of this application. Figure 1 As shown, the display panel 110 provided in this application embodiment includes: a hole area 111, including a first side L and a second side R disposed opposite to each other; a display area 112 surrounding the hole area 111, including a plurality of pixel units P arranged sequentially along a first direction T; a non-display area 113 surrounding the display area 112; and a first signal line A10 and a second signal line A20, which have the same function and are at least partially disposed in the non-display area 113. The first signal line A10 is at least partially disposed in the first side L, and the second signal line A20 is at least partially disposed in the second side R. The first signal line A10 is electrically connected to the pixel units P of the first side L and the second side R sequentially along the first direction T, and the second signal line A20 is electrically connected to the pixel units P of the first side L and the second side R sequentially along the opposite direction of the first direction T.

[0032] It should be noted that the first direction T refers to the direction perpendicular to the edge of the first side L or the second side R, and the first direction T points towards the second side R. For example... Figure 1 As shown, the first direction T is the horizontal direction to the right.

[0033] In some embodiments, the aperture region 111 is used to accommodate a camera. The first signal line A10 and the second signal line A20 may be GIP signal lines that drive the pixel unit P to emit light, wherein the GIP signal lines include at least one of the EIN signal line, ECK1 signal line, ECK2 signal line, SIN signal line, SCK1 signal line, and SCK2 signal line.

[0034] In some embodiments, the first signal line A10 is arranged parallel to the first side L edge of the display area 112, and the second signal line A20 is arranged parallel to the second side R edge of the display area 112.

[0035] In some embodiments, the connecting line electrically connecting the first signal line A10 to the pixel unit P on the first side L and the second side R, and the connecting line electrically connecting the second signal line A20 to the pixel unit P on the first side L and the second side R, can be the same connecting line to simplify the circuit structure and facilitate manufacturing; or they can be two connecting lines to reduce signal interference between the first signal line A10 and the second signal line A20. This application does not further limit the specific connection method of the connecting lines, and can set it according to actual needs.

[0036] In some embodiments, the first signal line A10 can be electrically connected to the pixel unit P on the first side L and the second side R via a signal line having the same function as the first signal line A10, and the second signal line A20 can be electrically connected to the pixel unit P on the first side L and the second side R via a signal line having the same function as the second signal line A20. The connection line between the pixel unit P on the first side L and the pixel unit P on the second side R surrounds the edge of the aperture region 111.

[0037] In this embodiment, by electrically connecting the first signal line A10 to the pixel unit P of the first side L and the second side R, and the second signal line A20 to the pixel unit P of the first side L and the second side R, the pixel unit P of the first side L and the second side R can still be displayed normally by relying on the other signal line when one of the first signal line A10 or the second signal line A20 experiences an open circuit or short circuit fault. This effectively avoids the phenomenon of abnormal display caused by open circuit or short circuit of the signal line.

[0038] Figure 2 The image shown is a schematic diagram of the structure of a display panel provided in another exemplary embodiment of this application. Figure 1 This application extends from the embodiments shown. Figure 2 The illustrated embodiment will be described in detail below. Figure 2 The illustrated embodiments and Figure 1 The differences between the embodiments shown are not repeated here, and the similarities are not repeated here.

[0039] like Figure 2 As shown, the display panel 110 also includes a first driving line B10 extending along the first direction T. One end of the first driving line B10 is electrically connected to the first signal line A10 and the other end is electrically connected to the second signal line A20. The first driving line B10 is electrically connected to the pixel units P of the first side L and the second side R in sequence along the first direction T. The first driving line B10 is at least partially disposed in the display area 112.

[0040] In some embodiments, a first driving line B10 between pixel unit P on the first side L and pixel unit P on the second side R surrounds the edge of the aperture region 111. The display panel 110 provided in this application embodiment has simple wiring and low manufacturing cost.

[0041] Figure 3 The image shown is a second schematic diagram of the structure of a display panel provided in another exemplary embodiment of this application. In this application... Figure 2 This application extends from the embodiments shown. Figure 3 The illustrated embodiment will be described in detail below. Figure 3 The illustrated embodiments and Figure 2 The differences between the embodiments shown are not repeated here, and the similarities are not repeated here.

[0042] like Figure 3As shown, on the first side L, the first signal line A10 includes a first segment A11 and a second segment A12. The first segment A11 and the second segment A12 are arranged parallel to each other along the second direction V, and the same end of the first segment A11 and the second segment A12 are electrically connected along the second direction V. On the second side R, the second signal line A20 includes a third segment A23 and a fourth segment A24. The third segment A23 and the fourth segment A24 are arranged parallel to each other along the second direction V, and the same end of the third segment A23 and the fourth segment A24 are electrically connected along the second direction V. Wherein, the electrical connection of the first segment A11 and the second segment A12 at the same end along the second direction V means that the first signal line A10 also includes a connecting line electrically connecting one end of the first segment A11 and one end of the second segment A12, and the connecting line between the first segment A11 and the second segment A12 has the same function as the first segment A11 and the second segment A12; the electrical connection of the third segment A23 and the fourth segment A24 at the same end along the second direction V means that the second signal line A20 also includes a connecting line electrically connecting one end of the third segment A23 and one end of the fourth segment A24, and the connecting line between the third segment A23 and the fourth segment A24 has the same function as the third segment A23 and the fourth segment A24.

[0043] It should be noted that the second direction V refers to the direction parallel to the edge of the first side L or the second side R. For example... Figure 3 As shown, the second direction V is the vertically upward direction.

[0044] In some embodiments, on the first side L, a first segment A11 extends from one end of the first signal line A10 in a direction parallel to the edge of the first side L of the display area 112, and a second segment A12 is parallel to the first segment A11. On the second side R, a third segment A23 extends from one end of the second signal line A20 in a direction parallel to the edge of the second side R of the display area 112, and a fourth segment A24 is parallel to the third segment A23.

[0045] In some embodiments, if one of the first signal line A10 and the second signal line A20 experiences an open circuit fault, the pixel unit P on the first side L and the second side R will only be driven to emit light by the one signal line that is not faulty, resulting in uneven display. To solve this problem, the display panel 110 provided in this application embodiment includes two segments for both the first signal line A10 and the second signal line A20. When one segment of one of the signal lines experiences an open circuit fault, the pixel unit P on the first side L and the second side R can be driven to emit light by the other segment and the other signal line. This ensures that the pixel unit P on the first side L and the second side R is still driven to emit light simultaneously by the first signal line A10 and the second signal line A20 on both sides, avoiding the uneven display problem caused by only being driven to emit light by one signal line.

[0046] Specifically, such as Figure 3As shown, drive signals are input from both ends of the first signal line A10, that is, from one end of the first segment A11 and one end of the second segment A12. The drive signals are transmitted along the first segment A11 and the second segment A12. Figure 3 Taking the open circuit fault at point C in the first segment A11 as an example, the drive signal input from one end of the second segment A12 is interrupted when it reaches point C, and the drive signal input from one end of the first segment A11 is also interrupted when it reaches point C. However, the first signal line A10 from the signal input end of the second segment A12 to point C and the first signal line A10 from the signal input end of the first segment A11 to point C can normally drive the pixel unit P of the display area 112, except for the pixel unit P corresponding to point C, to emit light. In addition, the second signal line A20 normally drives the pixel unit P of the display area 112 to emit light, effectively avoiding the problem of uneven display.

[0047] Figure 4 The third schematic diagram shows the structure of a display panel provided in another exemplary embodiment of this application. Figure 3 This application extends from the embodiments shown. Figure 4 The illustrated embodiment will be described in detail below. Figure 4 The illustrated embodiments and Figure 3 The differences between the embodiments shown are not repeated here, and the similarities are not repeated here.

[0048] like Figure 4 As shown, the first segment A11 and the second segment A12 are each electrically connected to one end of the first drive line B10, and the third segment A23 and the fourth segment A24 are each electrically connected to the other end of the first drive line B10.

[0049] In some embodiments, the connection point between the signal line and the drive line is easily broken or corroded by moisture, thus the connection point is prone to open circuit and short circuit faults, resulting in abnormal display in the display area 112. To reduce the probability of the above problems, in the display panel 110 provided in this application embodiment, the first segment A11 and the second segment A12 are each electrically connected to one end of the first drive line B10. When an open circuit fault occurs at the connection point of one segment with the first drive line B10, the pixel units P on the first side L and the second side R can be driven to emit light by the electrical connection of the other segment with the first drive line B10, and the display can still display normally. Similarly, the third segment A23 and the fourth segment A24 are each electrically connected to the other end of the first drive line B10. When an open circuit fault occurs at the connection point of one segment with the first drive line B10, the pixel units P on the first side L and the second side R can be driven to emit light by the electrical connection of the other segment with the first drive line B10, and the display can still display normally.

[0050] Figure 5 The fourth illustration shows the structure of a display panel provided in another exemplary embodiment of this application. Figure 1 This application extends from the embodiments shown. Figure 5 The illustrated embodiment will be described in detail below. Figure 5 The illustrated embodiments and Figure 1 The differences between the embodiments shown are not repeated here, and the similarities are not repeated here.

[0051] like Figure 5 As shown, the display panel 110 provided in this embodiment further includes a second driving line B20 electrically connected to the pixel unit P on the first side L, and a third driving line B30 electrically connected to the pixel unit P on the second side R. Both the second driving line B20 and the third driving line B30 are at least partially disposed in the display area 112. Specifically, the second driving line B20 extends in the opposite direction to the first direction T to be electrically connected to the first signal line A10, and the third driving line B30 is electrically connected to the first signal line A10 via the second driving line B20. The third driving line B30 extends in the first direction T to be electrically connected to the second signal line A20, and the second driving line B20 is electrically connected to the second signal line A20 via the third driving line B30. In other words, the first signal line A10 is electrically connected to the second driving line B20, and the first signal line A10 is also electrically connected to the third driving line B30; the second signal line A20 is electrically connected to the second driving line B20, and the second signal line A20 is also electrically connected to the third driving line B30.

[0052] In some embodiments, the pixel unit P on the first side L and the pixel unit P on the second side R are electrically connected to different driving lines, thereby reducing the interference between the driving signals received by the pixel unit P on the first side L and the pixel unit P on the second side R, and effectively avoiding abnormal display phenomena.

[0053] Figure 6 The fifth illustration shows the structure of a display panel provided in another exemplary embodiment of this application. Figure 5 This application extends from the embodiments shown. Figure 6 The illustrated embodiment will be described in detail below. Figure 6 The illustrated embodiments and Figure 5 The differences between the embodiments shown are not repeated here, and the similarities are not repeated here.

[0054] like Figure 6 As shown, the first signal line A10 extends around the edge of the display area 112 to the second side R. The first signal line A10 located on the first side L is electrically connected to the second driving line B20, and the first signal line A10 located on the second side R is electrically connected to the third driving line B30. The second signal line A20 extends around the edge of the display area 112 to the first side L. The portion of the second signal line A20 located on the first side L is electrically connected to the second driving line B20, and the portion of the second signal line A20 located on the second side R is electrically connected to the third driving line B30.

[0055] In some embodiments, due to the limited space at the edge of the aperture area 111, accommodating too many traces will inevitably increase the risk of short circuits and easily cause signal interference between traces. To solve the above problems, in the display panel 110 provided in this application embodiment, neither the second driving line B20 nor the third driving line B30 passes through the aperture area 111. Figure 6 The electrical connection method shown avoids routing traces at the edge of the hole area 111, reducing the risk of short circuits. It also achieves electrical connection between the first signal line A10 and the pixel unit P on the first side L and the second side R, and between the second signal line A20 and the pixel unit P on the first side L and the second side R. This further reduces the risk of display abnormalities caused by open circuits and short circuits in the signal lines.

[0056] Figure 7 The image shown is a sixth schematic diagram of the structure of a display panel provided in another exemplary embodiment of this application. In this application... Figure 5 This application extends from the embodiments shown. Figure 7 The illustrated embodiment will be described in detail below. Figure 7 The illustrated embodiments and Figure 5 The differences between the embodiments shown are not repeated here, and the similarities are not repeated here.

[0057] like Figure 7 As shown, the first signal line A10 includes a fifth segment A15 and a sixth segment A16. The fifth segment A15 extends from one end of the first signal line A10 around the edge of the display area 112 to the second side R, and the sixth segment A16 is arranged parallel to the fifth segment A15. The second signal line A20 includes a seventh segment A27 and an eighth segment A28. The seventh segment A27 extends from one end of the second signal line A20 around the edge of the display area 112 to the first side L, and the eighth segment A28 is arranged parallel to the seventh segment A27. The fifth segment A15 and the seventh segment A27 located on the first side L are both electrically connected to the second driving line B20, and the fifth segment A15 and the seventh segment A27 located on the second side R are both electrically connected to the third driving line B30. In addition, the first signal line A10 also includes a connecting line that electrically connects one end of the fifth segment A15 and one end of the sixth segment A16. The connecting line between the fifth segment A15 and the sixth segment A16 has the same function as the fifth segment A15 and the sixth segment A16. The second signal line A20 also includes a connecting line that electrically connects one end of the seventh segment A27 and one end of the eighth segment A28. The connecting line between the seventh segment A27 and the eighth segment A28 has the same function as the seventh segment A27 and the eighth segment A28.

[0058] In some embodiments, to reduce the impact of an open circuit fault in the first signal line A10 or the second signal line A20 on the display, both the first signal line A10 and the second signal line A20 include two parallel segments. Based on... Figure 3Following the same principle as the illustrated embodiment, when a section of the first signal line A10 experiences an open circuit fault, the portion of the first signal line A10 other than the open circuit fault point can normally drive the pixel units P of the display area 112, except for the pixel unit P corresponding to the open circuit fault point, to emit light. Similarly, when a section of the second signal line A20 experiences an open circuit fault, the portion of the second signal line A20 other than the open circuit fault point can normally drive the pixel units P of the display area 112, except for the pixel unit P corresponding to the open circuit fault point, to emit light, thereby reducing the impact of signal line open circuits on the display.

[0059] Figure 8 The seventh illustration shows the structure of a display panel provided in another exemplary embodiment of this application. Figure 7 This application extends from the embodiments shown. Figure 8 The illustrated embodiment will be described in detail below. Figure 8 The illustrated embodiments and Figure 7 The differences between the embodiments shown are not repeated here, and the similarities are not repeated here.

[0060] like Figure 8 As shown, the sixth segment A16 and the eighth segment A28 located on the first side L are also electrically connected to the second drive line B20, and the sixth segment A16 and the eighth segment A28 located on the second side R are also electrically connected to the third drive line B30.

[0061] In some embodiments, the connection points between signal lines and drive lines are easily broken or corroded by moisture, thus making them prone to open circuits and short circuits, leading to abnormal display in display area 112. To reduce the probability of the above problems, the display panel 110 provided in this application embodiment has its fifth segment A15, sixth segment A16, seventh segment A27, and eighth segment A28 on the first side L electrically connected to the second drive line B20. When an open circuit occurs at the connection point of one of these segments with the second drive line B20, the pixel unit P on the first side L can be driven to emit light by the electrical connection of the other segments with the second drive line B20. Similarly, the fifth segment A15, sixth segment A16, seventh segment A27, and eighth segment A28 on the second side R are all electrically connected to the third drive line B30. When an open circuit occurs at the connection point of one of these segments with the third drive line B30, the pixel unit P on the second side R can be driven to emit light by the electrical connection of the other segments with the third drive line B30, thereby reducing the probability of abnormal display.

[0062] In some embodiments, the driving lines (including the first driving line B10, the second driving line B20 and the third driving line B30) can be signal lines processed by the first signal line A10 and the second signal line A20 through the GIP signal processing circuit.

[0063] In some embodiments, the pixel unit P includes a driving transistor, which includes a source and a drain. At least a portion of the first signal line A10 and at least a portion of the second signal line A20 are disposed in the same layer as the source and drain, so that they can be fabricated in a single etching process, simplifying the fabrication process and reducing the manufacturing cost.

[0064] Figure 9 The diagram shown is a structural schematic of a display device provided in an exemplary embodiment of this application. Figure 9 As shown, one embodiment of this application also provides a display device 100. It is understood that the display panel 110 can be applied to the display device 100, which can be, for example, any product or component with display functionality such as a mobile terminal, tablet computer, computer monitor, television, wearable device, or information kiosks. The display device 100 includes the display panel 110 as in any embodiment of this application, and its technical principles and effects are similar, so they will not be described again here.
