Referring to fig. 1 and fig. 2, an embodiment of the present application provides a display panel 10. The display panel 10 includes an opening region 110, at least one first multiplexing control switch unit 210, a plurality of first signal lines 310, at least one second multiplexing control switch unit 220, a plurality of second signal lines 320, and a plurality of third signal lines 330.

The opening region 110 is disposed on the display panel 10. The display panel 10 may include a substrate 100. The substrate 100 is provided with the open region 110. The at least one first multiplexing control switch unit 210 and the plurality of first signal lines 310 are disposed at a first side of the open region 110. At least two of the first signal lines 310 are connected to one of the first multi-way control switch units 210. The at least one second multiplexing control switch unit 220 and the plurality of second signal lines 320 are disposed at a second side of the open region 110. At least two of the second signal lines 320 are connected to one of the second multi-way control switch units 220. The plurality of third signal lines 330 are disposed around the open region 110. One of the third signal lines 330 is connected to one of the first multi-way control switch units 210 and one of the second multi-way control switch units 220, respectively. The third signal line 330 is used to connect the first signal line 310 and the second signal line 320. The first signal lines 310 and the second signal lines 320 are connected in a one-to-one correspondence through the first multi-way control switch unit 210 and the second multi-way control switch unit 220.

The opening 110 can be used to install a camera, a gravity sensor, an infrared sensor, a receiver, a light sensor, etc. The shape of the open area 110 may be set as desired. The shape of the open area 110 may be circular or polygonal, etc.

The display panel 10 further includes a display area 120. The display region 120 may be disposed on the substrate 100. The open area 110 may be disposed in the middle of the display area 120. When the open region 110 is disposed in the middle of the display region 120, the display region 120 may surround the open region 110.

Referring to fig. 3 and 4, in an embodiment, the opening region 110 may be further disposed at an edge of the display region 120. When the opening region 110 is disposed at the edge of the display region 120, the display region 120 may be disposed around at least a portion of the opening region 110. It is understood that the surface of the open area 110 may also be provided with an array of pixels.

The pixel array may be turned on or off as desired. In one embodiment, the opening area 110 is provided with a camera. When the camera is turned on, the pixel array corresponding to the opening region 110 may be turned off. And the corresponding position of the pixel array is used for lighting. When the camera is turned off, the pixel array corresponding to the opening region 110 may be turned on to implement display. Therefore, when the camera is turned off, the display panel 10 has a larger area having a display function, thereby having a higher screen occupation ratio.

In one embodiment, the first multiplexing control switch unit 210 and the second multiplexing control switch unit 220 may carry multiple signals for communication through the same transmission line. In one embodiment, the first and second multiplexing

control switch units

210 and 220 may have a plurality of signal channels. The plurality of signal channels may be connected to the transmission line. The first multi-way control switch unit 210 and the second multi-way control switch unit 220 can communicate one or more signal channels according to requirements.

The first signal line 310 and the second signal line 320 may be data lines or scan lines. The number of the first signal lines 310 and the second signal lines 320 may be the same. The first signal lines 310 and the second signal lines 320 are disposed in one-to-one correspondence.

The first signal line 310 and the second signal line 320 are respectively located at a first side and a second side of the open region 110. A plurality of the first multi-way control switch units 210 and a plurality of the second multi-way control switch units 220 are also respectively disposed at the first side and the second side. The first side and the second side may be opposite sides of the open area 110. The first side and the second side may also be non-adjacent sides having a distance. The first signal lines 310 and the second signal lines 320 are respectively connected in a one-to-one correspondence manner through the first multi-way control switch unit 210 and the second multi-way control switch unit 220.

It is understood that a plurality of the first signal lines 310 and a plurality of the second signal lines 320 may be arranged in parallel at the first side and the second side, respectively. The plurality of first multi-way control switch units 210 and the plurality of first multi-way control switch units 210 may be arranged in a straight line shape, or may be arranged in an arc shape.

In the display panel 10 provided in the embodiment of the present application, at least two first signal lines 310 are connected to one first multiplexing control switch unit 210. The first multi-way control switch unit 210 is connected to one of the second multi-way control switch units 220 through one of the third signal lines 330. The second multiplexing control switch unit 220 is further connected to at least two second signal lines 320. The number of the first signal lines 310 to which one of the first multi-control switch units 210 is connected and the number of the second signal lines 320 to which one of the second multi-control switches is connected may be the same. The third signal line 330 may be disposed around the open region 110.

On a first side of the opening area 110, each of the first multiplexing control switch units 210 connects at least two of the first signal lines 310 with one of the third signal lines 330. The third signal line 330 surrounds the open region 110 and extends from a first side of the open region 110 to a second side of the open region 110. On a second side of the opening area 110, each of the second multi-way control switch units 220 connects one of the third signal lines 330 with at least two of the second signal lines 320. Therefore, the first signal lines 310 are communicated with the first multi-way control switch unit 210, the third signal lines 330 and the second signal lines 320 in a one-to-one correspondence manner, so that signals are transmitted from the first side of the open region 110 to the second side of the open region. Through the arrangement mode, the signal wires surrounding the edge of the opening area 110 are reduced by at least half, so that the wiring space at the edge of the opening area 110 is saved. The display panel 10 has a larger display area due to the reduced wiring space at the edge of the opening region 110.

When the first signal line 310 passes through the open area 110, the signals of at least two first signal lines 310 pass through one third signal line 330, i.e., the signal line surrounding the edge of the open area 110, by at least half when passing through the first multi-way control switch unit 210, thereby saving the wiring space around the open area 110. Similarly, the density of the signal lines around the edge of the opening area 110 is also significantly reduced in the same wiring space, so that the signal lines can be prevented from interfering with each other.

It is understood that the first and second multi-way

control switch units

210 and 220 may switch different signal channels such that the first and

second signal lines

310 and 320 are connected differently.

In one embodiment, the first and second multiplexing

control switch units

210 and 220 may be connected to 4 or 8 first and

second signal lines

310 and 320, respectively. That is, the number of signal lines surrounding the opening area 110 may be changed to the previous 1/4 or 1/8 by the first and second multi-way

control switch units

210 and 220.

Referring to fig. 5, in an embodiment, the display panel 10 further includes a first wiring layer 410, a first insulating layer 450, and a second wiring layer 420. The first wiring layer 410 is disposed on the surface of the substrate 100. The first wiring layer 410 includes a plurality of the third signal lines 330 arranged at intervals. The first insulating layer 450 covers the first wiring layer 410. The second wiring layer 420 covers the first insulating layer 450. The second wiring layer 420 includes a plurality of the third signal lines 330 arranged at intervals. The plurality of third signal lines 330 in the first wiring layer 410 are arranged to be staggered with respect to the plurality of third signal lines 330 in the second wiring layer 420.

The first wiring layer 410, the first insulating layer 450, and the second wiring layer 420 are sequentially disposed at one side of the substrate 100. The third signal line 330 may be formed at the first wiring layer 410. It is understood that the first wiring layer 410 may be a metal layer. The metal layer may be made of copper, aluminum, gold, silver, or an alloy material containing silver or copper. A plurality of the third signal lines 330 are formed by etching the metal layer. Similarly, the second wiring layer 420 may also be a metal layer. The third signal line 330 may be formed by etching the metal layer. The metal layer may be made of copper, aluminum, gold, silver, or an alloy material containing silver or copper. Compared to a certain number of the third signal lines 330 being disposed on the same wiring layer.

The third signal lines 330 in the first wiring layer 410 and the third signal lines 330 in the second wiring layer 420 are disposed in a staggered manner, that is, orthographic projections of the third signal lines 330 in the first wiring layer 410 and the third signal lines 330 in the second wiring layer 420 on the substrate 100 may be parallel to each other, or may have overlapping portions. By disposing the plurality of third signal lines 330 in the first wiring layer 410 and the plurality of third signal lines 330 in the second wiring layer 420 in an interlaced manner, the facing areas of the plurality of third signal lines 330 in the first wiring layer 410 and the plurality of third signal lines 330 in the second wiring layer 420 can be reduced, thereby reducing the parasitic capacitance effect. By providing the same number of third signal lines 330 in the first wiring layer 410 and the second wiring layer 420, respectively, the wiring area of the electrical signal lines can be reduced, thereby saving space around the opening region 110.

The first insulating layer 450 may be an interlayer dielectric. The material of the first insulating layer 450 may be silicon dioxide, silicon nitride, phosphosilicate, or the like. In one embodiment, orthographic projections of the third signal lines 330 on the first wiring layer 410 and the third signal lines 330 on the second wiring layer 420 on the surface of the substrate 100 are not overlapped. That is, the third signal line 330 located in the first wiring layer 410 and the third signal line 330 located in the second wiring layer 420 do not have any facing area. Therefore, interference of the parasitic capacitance with the signal can be avoided.

In one embodiment, a passivation layer 480 is further disposed between the substrate 100 and the first wiring layer 410. The passivation layer 480 may prevent an electrochemical corrosion phenomenon. The passivation layer 480 may also be a multi-layer structure. The passivation layer 480 may be made of silicon nitride or silicon oxide.

The passivation layer 480 may be directly formed on the surface of the substrate 100. The first wiring layer 410 may be formed on a surface of the passivation layer 480. The first insulating layer 450 covers the surface of the first wiring layer 410.

In one embodiment, orthographic projections of the third signal lines 330 on the first wiring layer 410 and the third signal lines 330 on the second wiring layer 420 on the surface of the substrate 100 are exactly spliced into a plane. Therefore, the area of the first wiring layer 410 and the area of the second wiring layer are fully utilized, and the area of the traces around the opening region 110 is reduced. Meanwhile, the influence of the generated parasitic capacitance on the signal is also avoided.

In one embodiment, the display panel 10 further includes a plurality of control signal lines 340. The plurality of control signal lines 340 are disposed around the open region 110. Each of the control signal lines 340 is connected to a plurality of the first multi-way control switch units 210 and a plurality of the second multi-way control switch units 220, respectively. The control signal line 340 may be configured to control the plurality of first multiplexing control switch units 210 and the plurality of second multiplexing control switch units 220 to perform line switching, and may enable the plurality of first signal lines 310 and the plurality of second signal lines 320 to operate in different periods.

Referring to fig. 2 again, the control signal line 340 may be connected to the driving unit 500. The driving unit 500 may be a driving chip. The driving unit 500 controls the operating states of the first multi-way control switch unit 210 and the second multi-way control switch unit 220 by controlling the control signal line 340.

Referring to fig. 6, in an embodiment, the first multi-way control switch unit 210 and the second multi-way control switch unit 220 are respectively formed by at least two thin film transistors. A first electrode of each of the thin film transistors may be connected to one of the first signal lines 310 or one of the second signal lines 320, respectively. Accordingly, the thin film transistors in the first and second multi-way

control switch units

210 and 220 may be the same as the number of the first signal lines 310 and the number of the second signal lines 320 to which each of the first and second multi-way

control switch units

210 and 220 is connected, respectively.

The second poles of the two thin film transistors may be connected to one of the control signal lines 340, respectively. The number of the control signal lines 340 may also be the same as the number of the thin film transistors in the first and second multi-way

control switch units

210 and 220. One of the control signal lines 340 may be used to control an operation state of one of the thin film transistors in one of the first multi-way control switch units 210 or one of the second multi-way control switch units 220. The thin film transistor may be turned on by controlling a gate of one thin film transistor, so that the first signal line 310 and the second signal line 320 corresponding to the thin film transistor are turned on.

In one embodiment, the first pole may be a source. The second pole may be a drain.

In one embodiment, when the number of the thin film transistors in each of the first and second multi-way

control switch units

210 and 220 is two, two drains of the thin film transistors may be connected. Therefore, the drains of the two thin film transistors in the first multi-way control switch unit 210 and the drains of the two thin film transistors in the second multi-way control switch unit 220 may be connected through the third signal line 330.

In one embodiment, the display panel 10 further includes a second insulating layer 460 and a third wiring layer 430. The second insulating layer 460 covers the surface of the second wiring layer 420. The third wiring layer 430 includes the control signal line 340. The third wiring layer 430 covers the surface of the second insulating layer 460. The second insulating layer 460 may insulate the second wiring layer 420 and the third wiring layer 430. The second insulating layer 460 may also be an interlayer dielectric layer, and the material of the second insulating layer 460 may be silicon dioxide, silicon nitride, phosphosilicate, or the like.

The third wiring layer 430 may also be a metal layer, and the control signal line 340 may be obtained by patterning the metal layer. It is to be understood that, around the open region 110, the control signal line 340 may be disposed to the third wiring layer 430 around the open region 110.

In one embodiment, the display panel 10 is further provided with the display area 120. The display area 120 is disposed around the open area 110. The display panel 10 further includes a third insulating layer 470 and an electrode layer 440. The third insulating layer 470 covers the surface of the third wiring layer 430. The electrode layer 440 covers the surface of the third insulating layer 470. The control signal line 340 extends from the display region 120 to the edge of the substrate 100 through the electrode layer 440. In one embodiment, the third insulating layer 470 may be a planarization layer.

When the opening region 110 is disposed at the edge of the display panel 10, the display region 120 may be disposed to half surround the display panel 10. When the open region 110 is disposed in the middle of the display panel 10, the display region 120 may be disposed around the open region 110. The third insulating layer 470 may insulate the third wiring layer 430 from the electrode layer 440. It is understood that the electrode layer 440 may be in the same layer as the anode layer for driving the light emitting layer to emit light. The electrode layer 440 and the anode layer may be formed in the same process step. In the display area 120, since there is a pixel array, a plurality of VDD signal lines and Vdate signal lines are provided in the third wiring layer 430. Therefore, the third wiring layer 430 has a small wiring area. If the control signal line 340 passes through the third wiring layer 430 directly in the display area 120, the distance between lines may be further reduced, the wiring density may be increased, and the risk of short-circuiting may easily occur. Therefore, in the display region 120, the control signal line 340 can be connected to the driving unit 500 through the electrode layer 440, so that the control signal line 340 can be prevented from occupying the area of the third wiring layer 430, and the risk of short circuit can be reduced. It is understood that the driving unit 500 may be disposed at an edge of the display panel 10. The control signal line 340 may be connected to the driving unit 500 through the display area 120.

Referring to fig. 3 again, in an embodiment, the display panel 10 further includes a routing area 130. The routing area 130 may be disposed on the substrate 100. The wiring area 130 is disposed between the display area 120 and the opening area 110. The control signal line 340 extends from the routing area 130 to the display area 120. Referring to fig. 7, the third insulating layer 470 is provided with a via 472 between the routing area 130 and the display area 120. The control signal line 340 in the third wiring layer 430 is connected to the control signal line 340 in the electrode layer 440 through the via 472. It is understood that the routing area 130 may be disposed around the open area 110. The outline of the routing region 130 may be the same as the outline of the open region 110. The third signal line 330 and the control signal line 340 can be disposed in the routing area 130. The side of the routing area 130 away from the opening area 110 is the display area 120. Therefore, when the control signal line 340 is connected to the driving unit 500, the control signal line 340 needs to extend to the display area 120 through the wiring area 130.

It is understood that the opening region 110 and the routing region 130 may not be provided with a pixel array. The pixel array is disposed in the display area 120. As can be seen from the above analysis, in the routing area 130, the control signal line 340 may be disposed in the third wiring layer 430. In the display region 120, the control signal line 340 may be disposed on the electrode layer 440. The third insulating layer 470 may be provided with the via hole 472 at a boundary of the routing area 130 and the display area 120.

The plurality of control signal lines 340 are respectively connected to the first multi-way control switch unit 210 and the second multi-way control switch unit 220 from the same side or both sides of the opening area 110. When the plurality of control signal lines 340 are connected to the first multi-way control switch unit 210 and the second multi-way control switch unit 220 from the same side of the opening region 110, the space on the other side of the opening region 110 can be saved, and therefore, other sensing devices or pixel arrays can be arranged on the other side as required. When the plurality of control signal lines 340 are disposed on two sides of the opening region 110, the width of the wiring regions on the two sides of the opening region 110 may be the same.

In one embodiment, the plurality of first multiplexing control switch units 210 are arranged in a circular arc around the open region 110 on the first side. The plurality of second multi-way control switch units 220 are arranged in a circular arc around the open region 110 at the second side. That is, the plurality of first multi-way control switch units 210 and the plurality of second multi-way control switch units 220 may have the same tendency as the open region 110. The arrangement of the first and second multi-way

control switch units

210 and 220 with respect to the opening region 110 can be made more compact, saving space.
