Detailed Description
Embodiments of the present invention provide a display panel and a display device, and in order to make objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The shapes and sizes of the various elements in the drawings are not to scale and are merely intended to illustrate the invention.
As shown in fig. 1 and fig. 3, the display panel according to an embodiment of the present invention includes an array substrate 01 and an opposite substrate 02 (not shown in fig. 1) which are disposed opposite to each other, and a plurality of first traces 011 located on the array substrate 01 and extending along a first direction; wherein the content of the first and second substances,
the display panel has a display area A and a hole-digging area BB surrounded by the display area A;
at least one part corresponding to the excavated region BB extends the first trace 011 along the first direction F1 to penetrate the excavated region BB along the first direction F1;
the array substrate 01 comprises a plurality of first through holes V1 penetrating through the array substrate 01 and arranged in a hole digging area BB, the opposite substrate 02 comprises a plurality of second through holes V2 (shown in FIGS. 2 and 3) penetrating through the opposite substrate 02 and arranged in the hole digging area BB, and orthographic projections of the first through holes V1 and the second through holes V2 on the light-emitting surface of the display panel are at least partially overlapped; in addition, the orthographic projection of the first via V1 and the first trace 011 on the light emitting surface of the display panel is not overlapped.
To explain this point, in the embodiment of the present invention, as shown in fig. 2 and fig. 3, the array substrate 01 and the opposite substrate 02 are both generally composed of substrate boards, wherein the substrate board included in the array substrate 01 may be referred to as a first substrate board, denoted by 010, and the substrate board included in the opposite substrate 02 may be referred to as a second substrate board, denoted by 020, and the first trace 011 included in the array substrate 01 is disposed on the first substrate board 010.
Of course, in the array substrate 01, in addition to the first trace 011 located on the first substrate 010, other film layer structures are also included, wherein the sum of the through hole in the other film layer structures, the through hole in the film layer where the first trace 011 is located, and the through hole in the first substrate 010 is referred to as a first through hole V1, so the first through hole V1 penetrates through all the film layers on the first substrate 010 and the first substrate 010. Similarly, the second through hole V2 and the first through hole V1 have the same configuration, and the description thereof is omitted.
In the display panel provided by the embodiment of the invention, although the excavated region BB is surrounded by the display region a, at least part of the first wiring 011 corresponding to the excavated region BB on the display panel penetrates through the excavated region BB along the first direction F1, so that the first wiring 011 corresponding to the excavated region BB is prevented from being arranged around the excavated region BB, and thus the length difference of each first wiring 011 on the display panel is reduced, the inconsistency of wiring RC Loading caused by the inconsistency of wiring lengths is alleviated, and the display quality is improved. In addition, the first routing line 011 does not need to be arranged around the excavated area BB, so that the peripheral width of the excavated area BB can be reduced, thereby realizing a higher screen occupation ratio.
In addition, the array substrate 01 includes a plurality of first through holes V1 penetrating through the array substrate 01 and provided in the cutout area BB, the counter substrate 02 includes a plurality of second through holes V2 penetrating through the counter substrate 02 and provided in the cutout area BB, and orthographic projections of the first through holes V1 and the second through holes V2 on the light-emitting surface of the display panel at least partially overlap. When the hole digging area BB corresponds to the earphone and other elements, the first through hole V1 and the second through hole V2 can ensure a high-quality sound propagation path and can also play a role of a dustproof net of the earphone.
Finally, since the orthographic projections of the first via V1 and the first trace 011 on the light emitting surface of the display panel are not overlapped, the problem that the service life of the display panel is affected due to the fact that the first via V1 directly exposes the first trace 011 in the air can be avoided, and normal display of the display panel can be ensured.
Optionally, in the display panel provided in the embodiment of the present invention, as shown in fig. 4, the first routing lines 011 corresponding to the excavated region BB all penetrate through the excavated region BB along the first direction F1. The first wiring 011 corresponding to the hole digging region BB can be prevented from being arranged around the hole digging region BB, so that the lengths of the first wirings 011 on the display panel are basically consistent, the inconsistency of wiring RC Loading caused by the inconsistency of the wiring lengths is avoided, and the display quality is guaranteed.
Optionally, in the display panel provided in the embodiment of the present invention, the excavated area is an earphone corresponding area for subsequently disposing earphones, when the excavated area corresponds to an earphone component, the first through hole and the second through hole may ensure a high-quality sound propagation path, and in addition, the size of the first through hole and the second through hole disposed in the excavated area is generally small, so that this structure may also function as an earphone dust screen, but the present invention is not limited thereto. The excavated area can also be used to position some other sensor, such as a gas detection element, so that the gas to be detected reaches the gas detection element through the through-hole.
Optionally, in the embodiment of the present invention, orthographic projections of the first through hole V1 and the second through hole V2 on the light exit surface of the display panel may completely coincide, as shown in fig. 3. In this way, it is possible to ensure higher-quality propagation of sound through the first through hole V1 and the second through hole V2 without being lost, and also to effectively play a role of dust prevention.
Alternatively, in the embodiment of the present invention, the size of the first through hole V1 and the second through hole V2 may be set to be the same (as shown in fig. 3), and the shape of the first through hole V1 and the second through hole V2 may also be set to be the same. Therefore, the first through hole V1 and the second through hole V2 can be manufactured by the same mask plate, so that the manufacturing cost is reduced, and meanwhile, when orthographic projections of the first through hole V1 and the second through hole V2 on the light emitting surface of the display panel are completely overlapped, the occupied area of a hole digging area is favorably reduced, the occupied area of a display area is further increased, and the display effect is improved.
Certainly, the size of the first through hole and the size of the second through hole can be set to be different, so that the first through hole and the second through hole can be manufactured according to actual needs, and the manufacturing flexibility of the first through hole and the second through hole is increased so as to adapt to display panels with more structures.
Optionally, in the embodiment of the present invention, for the second through hole, no matter whether the orthographic projections of the first through hole and the second through hole on the light emitting surface of the display panel are completely overlapped or partially overlapped, the orthographic projections of the second through hole and the first trace on the light emitting surface of the display panel may be set to be not overlapped, as shown in fig. 2 and 3, so as to prevent impurities such as dust and air entering through the second through hole from causing adverse effects on the first trace, thereby ensuring that the first trace can normally transmit a corresponding signal, so as to ensure normal display of the display panel.
Optionally, in the display panel provided in the embodiment of the present invention, the first trace generally includes a scan line, and certainly, the first trace also includes other traces extending along the first direction F1 in the display panel, which is not limited herein.
Optionally, in the display panel provided in the embodiment of the invention, as shown in fig. 5, the array substrate 01 includes a plurality of second routing lines 012 extending along a second direction F2, where the first direction F1 intersects the second direction F2. The first direction F1 and the second direction F2 may be perpendicular to each other, as shown in fig. 5, or may not be perpendicular to each other (not shown), as long as they are arranged according to the structure of the display panel and the actual needs, and are not limited herein.
At least a portion of the second trace 012 corresponding to the cutout area BB penetrates the cutout area BB in the second direction F2. In this arrangement, a part of the second wires 012 corresponding to the cutout area BB may penetrate through the cutout area in the second direction F2 (not shown), or all of the second wires 012 corresponding to the cutout area BB may penetrate through the cutout area in the second direction F2, as shown in fig. 5.
So, the second line 012 of running through the regional BB of digging hole can need not to set up around the regional BB of digging hole, thereby can make the length of the second line 012 on the display panel unanimous basically, thereby reduce the line RC Loading difference that leads to because the second line 012 length is inconsistent, display quality has been guaranteed, and, because the second line 012 runs through the regional of digging hole along second direction F2, need not set up around the edge of the regional BB of digging hole, consequently, can reduce the peripheral width of the regional BB of digging hole, thereby realize higher screen and account for the ratio.
Optionally, in the display panel provided in the embodiment of the present invention, the second traces generally include display signal lines, and certainly, the second traces also include other traces extending along the second direction F2 in the display panel, which is not limited herein.
In practical applications, in the display panel provided in the embodiment of the present invention, the shape of the hole-digging region may be a regular shape, such as a circle, a rectangle, etc., and of course, the shape of the hole-digging region may also be an irregular shape, and the shape of the hole-digging region mainly depends on the shape of the element to be disposed in the hole-digging region, and is not limited herein.
In practical implementation, in the display panel provided in the embodiment of the present invention, the shapes of the first through hole and the second through hole may be regular shapes, such as a circle, a rectangle, and the like, and may also be irregular shapes, which is not limited herein.
Optionally, in the display panel provided in the embodiment of the present invention, as shown in fig. 5, an orthogonal projection of the first through hole V1 on the light emitting surface of the display panel is not overlapped with an orthogonal projection of the second trace 012 on the light emitting surface of the display panel. Therefore, the influence on the service life of the display panel due to the fact that the first through hole V1 directly exposes the second wire 012 in the air can be avoided, and the normal display of the display panel can be ensured.
In addition, in the embodiment of the present invention, orthographic projections of the second through holes and the second wires on the light emitting surface of the display panel are not overlapped, and a diagram is not shown. Thus, the influence of the second trace 012 on the service life of the display panel due to the second through hole V2 directly exposing the second trace 012 in the air can be avoided, and the normal display of the display panel can be ensured.
Optionally, in the display panel provided in the embodiment of the present invention, as shown in fig. 6, an insulating protection structure 03 filled in the excavated area BB is disposed between the array substrate 01 and the opposite substrate 02; the insulating protection structure 03 is provided with a third through hole V3 penetrating through the insulating protection structure 03; the first through hole V1 on the array substrate 01 is connected to the first through hole V1 on the opposite substrate 02 through a third through hole V3 penetrating through the insulating protection structure 03, that is, orthogonal projections of the first through hole V1, the second through hole V2 and the third through hole V3 on the light emitting surface of the display panel overlap. In this way, the insulating protection structure 03 can protect the traces from dust or moisture entering from the first via V1 and the second via V2. In addition, a short circuit between the first trace 011 and the second trace 012 can be avoided, thereby increasing the lifetime of the display panel.
It should be noted that, the orthographic projections of the first through hole V1, the second through hole V2, and the third through hole V3 on the light emitting surface of the display panel overlap, it can be understood that the orthographic projections of the first through hole V1, the second through hole V2, and the third through hole V3 on the light emitting surface of the display panel partially overlap (not shown), and it can also be understood that the orthographic projections of the first through hole V1, the second through hole V2, and the third through hole V3 on the light emitting surface of the display panel completely overlap (as shown in fig. 6), but the invention is not limited thereto as long as the first trace 011 and the second trace 012 can be protected by the insulating protection structure 03.
In addition, when the display panel provided by the embodiment of the invention is a liquid crystal display panel, the insulating protection structure 03 can also prevent liquid crystal in the display area from flowing out through the first through hole and the second through hole.
In specific implementation, the insulating protection structure may be formed on the array substrate by a coating method and covers the first trace and the second trace, but may also be formed by other methods, which is not limited herein.
In a specific implementation, as shown in fig. 7 to 10, in the display panel provided in the embodiment of the present invention, a plurality of pixel units 04 are further disposed in the excavated area BB, and each pixel unit 04 includes a plurality of sub-pixel units.
Optionally, in the display panel provided in the embodiment of the present invention, the first through hole V1 may correspond to one sub pixel unit. Taking the first through holes V1 as an example, as shown in fig. 7, that is, each first through hole V1 overlaps with an orthogonal projection of one sub-pixel unit on the light emitting surface of the display panel, of course, the overlapped region may be any region of the sub-pixel unit, for example, the overlapped region may be located in a middle region of the sub-pixel unit (as shown in fig. 7) or in an edge region of the sub-pixel unit (not shown), and is not limited herein. Thus, the first through hole V1 can secure a high-quality sound propagation path, while the hole is small to play a role of dust prevention.
Or alternatively, in the display panel provided in the embodiment of the present invention, the first through hole V1 may also correspond to a plurality of sub-pixel units. For example, as shown in fig. 8 to 10, taking the case that each first through hole V1 overlaps with the orthographic projection of three or more sub-pixel units on the light emitting surface of the display panel, and each sub-pixel unit overlapping with the orthographic projection of the first through hole V1 on the light emitting surface of the display panel is regarded as one sub-pixel unit, the overlapped region may be located in the middle region of the sub-pixel unit combination (as shown in fig. 8), or in the edge region (not shown), and the like, which is not limited herein.
For another example, taking the example that each first through hole V1 overlaps with the orthographic projections of two sub-pixel units on the light emitting surface of the display panel, not shown in the drawings, and when two sub-pixel units are regarded as one sub-pixel unit combination, the overlapped region may be located in the middle region of the sub-pixel unit combination, or located in the edge region, and the like, and is not limited herein.
Thus, the first via V1 can correspond to a plurality of sub-pixel units, so the size of the first via V1 can be larger, and the manufacturing is easy, thereby reducing the manufacturing difficulty.
However, it should be noted that, for the first trace 011, when each of the first vias V1 corresponds to a plurality of sub-pixel units, in order to avoid the first via V1 overlapping with the first trace 011, the first trace 011 needs to be disposed at a position between the first vias V1. That is, part of the traces of the first trace 011 need to extend around the first via V1 along the second direction F2, and since the aperture of the first via is small, the length of part of the traces of the first trace 011 around the first via V1 along the second direction F2 is small, compared with the prior art that the traces are routed along the excavated area BB, in the embodiment of the present invention, the length of the extra trace is relatively small while the first trace 011 is routed around the first via V1, so that the length difference between the first trace 011 corresponding to the excavated area BB and the first trace 011 in other areas can be greatly reduced, thereby reducing the condition that the traces RC Loading is inconsistent due to the inconsistent lengths of the first trace 011.
Similarly, for the second trace 012, when each first via V1 corresponds to a plurality of sub-pixel units, in order to avoid the first via V1 overlapping with the second trace 012, the second trace 012 needs to be disposed at a position between the first vias V1. That is, the second trace 012 extends along the first direction F1 around the first through hole V1, but because the aperture of the first through hole is small, and the length of a part of the trace of the second trace 012 along the first direction F1 around the first through hole V1 is small, compared with the prior art that the trace is routed along the excavated area BB, the length of the trace that is added by the second trace 012 around the first through hole V1 in the embodiment of the present invention is relatively small, so that the length difference between the second trace 012 corresponding to the excavated area BB and the second trace 012 in other areas can be greatly reduced, thereby reducing the condition of inconsistent trace RC Loading caused by inconsistent lengths of the second trace 012.
Alternatively, in the display panel provided in the embodiment of the present invention, as shown in fig. 8 to 10, each of the first through holes V1 may correspond to one pixel unit 04. Taking the first through hole V1 as an example, that is, the first through hole V1 overlaps with the orthographic projection of one pixel unit on the light-emitting surface of the display panel, of course, the overlapped region may be located in the middle region of the pixel unit, or in the edge region, and is not limited herein.
In practical implementation, in the display panel provided in the embodiment of the present invention, as shown in fig. 7 and fig. 8, each pixel unit 04 includes a first color sub-pixel unit R, a second color sub-pixel unit G, and a third color sub-pixel unit B; or as shown in fig. 9 and 10, each pixel unit 04 includes one first color sub-pixel unit R, one second color sub-pixel unit G, one third color sub-pixel unit B, and one fourth color sub-pixel unit W.
In a specific implementation, the first color, the second color, and the third color may be a red sub-pixel unit, a green sub-pixel unit, and a blue sub-pixel unit, respectively. The fourth color is generally a white sub-pixel unit or a yellow sub-pixel unit, and is not limited herein.
In a specific implementation, the display panel provided in the embodiment of the present invention may be a liquid crystal display panel, and may also be an organic electroluminescence display panel, which is not limited herein.
When the display panel is a liquid crystal display panel, the array substrate generally further includes a thin film transistor, a pixel unit electrode and a common electrode, the opposite substrate generally further includes a photoresist layer, and a liquid crystal layer is further disposed between the array substrate and the opposite substrate.
When the display panel is an organic electroluminescent display panel, the array substrate generally further includes a pixel unit circuit and an organic electroluminescent structure. The organic electroluminescent structure generally includes an anode, a light-emitting layer, and a cathode. When the organic electroluminescent structure emits white light, a photoresist layer is generally further included on the opposite substrate.
Optionally, in the display panel provided in the embodiment of the present invention, the sub-pixel unit is only disposed in the display region. Namely, only the first trace and the second trace are disposed in the cut region, and the film layer, such as the insulating protection structure, is associated with the first trace and the second trace. Therefore, the structure of the display panel can be simplified, and the manufacturing difficulty of the display panel is reduced.
Optionally, in the display panel provided in the embodiment of the present invention, as shown in fig. 11, the display panel further has a high light transmission region C surrounded by the display region a; wherein the content of the first and second substances,
as shown in fig. 11, at least a portion of the first trace 011 corresponding to the high light transmission area C penetrates through the high light transmission area C along the first direction F1, and at least a portion of the second trace 012 corresponding to the high light transmission area C penetrates through the high light transmission area C along the second direction F2; the first trace 011 is made of a transparent conductive material in a portion penetrating through the high-transmittance region C, and the second trace 012 is made of a transparent conductive material in a portion penetrating through the high-transmittance region C.
It should be noted that, at least a portion of the first trace 011, which corresponds to the high light transmission region C, penetrates through the high light transmission region C along the first direction F1, it can be understood that a portion of the first trace 011, which corresponds to the high light transmission region C, penetrates through the high light transmission region C along the first direction F1, and it can also be understood that all of the first traces 011, which correspond to the high light transmission region C, penetrate through the high light transmission region C along the first direction F1, which is within the protection scope of the embodiments of the present invention.
Similarly, at least a portion of the second wires 012 corresponding to the high light transmission area C penetrate through the high light transmission area C along the second direction F2, it can be understood that a portion of the second wires 012 corresponding to the high light transmission area C penetrate through the high light transmission area C along the second direction F2, and it can be understood that all of the second wires 012 corresponding to the high light transmission area C penetrate through the high light transmission area C along the second direction F2.
In the display panel provided by the embodiment of the invention, although the high light transmission region is surrounded by the display region, at least a part of the first wires extending along the first direction F1 corresponding to the high light transmission region on the display panel penetrates through the high light transmission region along the first direction F1, and at least a part of the second wires extending along the second direction F2 corresponding to the high light transmission region penetrates through the high light transmission region along the second direction F2, so that the first wires and the second wires corresponding to the high light transmission region can be prevented from being arranged around the high light transmission region, the lengths of the first wires on the display panel are ensured to be basically consistent, the lengths of the second wires are basically consistent, the inconsistency of RC Loading caused by the inconsistency of the lengths of the wires is avoided, the display quality is ensured, and the peripheral width of the high light transmission region can be reduced because neither the first wires nor the second wires need to be arranged around the high light transmission region, thereby achieving a higher screen occupation ratio. In addition, the part of the first wiring penetrating through the high-light-transmission area is made of transparent conductive materials, and the part of the second wiring penetrating through the high-light-transmission area is made of transparent conductive materials, so that the first wiring and the second wiring can be prevented from influencing light transmission of the high-light-transmission area.
In practical implementation, in the display panel provided in the embodiment of the present invention, the shape of the high light transmittance region may be a regular shape, such as a circle, a rectangle, or the like, and of course, the shape of the high light transmittance region may also be an irregular shape, and the shape of the high light transmittance region mainly depends on the shape of the element that needs to be disposed in the high light transmittance region, and is not limited herein.

In specific implementation, the array substrate or the opposite substrate is formed on the array substrate or the opposite substrate in a coating mode, and when the array substrate and the opposite substrate are paired, the array substrate and the opposite substrate are filled between the array substrate and the opposite substrate.
To further explain the structure of the first trace and the second trace, first, the structures of the layers included in the array substrate in the display panel are briefly explained: generally, the side of the array substrate close to the opposite substrate includes multiple metal layers, for example, for a liquid crystal display panel, the side of the array substrate close to the opposite substrate includes a first metal layer, a second metal layer, the gate and the scan lines of the thin film transistor are located in the first metal layer, the source and the drain of the thin film transistor, and the display signal lines are located in the second metal layer.

Generally, under the same specification (length, width, and thickness), the resistance of ITO (Indium tin oxide) is greater than the resistances of the first metal layer, the third metal layer, and the second metal layer, so that the thickness of the first trace in the high-light-transmission region may be greater than the thickness of the first trace in the display region, and/or the width of the first trace in the high-light-transmission region may be greater than the width of the first trace in the display region, so as to achieve the purpose of reducing the resistance of the first trace in the high-light-transmission region. Similarly, the thickness of the second wire in the high-light-transmission area can be larger than the thickness of the second wire in the display area, and/or the width of the second wire in the high-light-transmission area can be larger than the width of the second wire in the display area, so that the purpose of reducing the resistance of the second wire in the high-light-transmission area is achieved.

Hollowing out the area of the backlight module 100 corresponding to the hollowed-out area BB can prevent the backlight module 100 from affecting the use of the components in the hollowed-out area BB, such as affecting the sound transmission of the handset.
Similarly, the area of the backlight module 100 corresponding to the high-transmittance area C is a hollow area, so that the backlight module 100 can be prevented from affecting the use of the elements in the high-transmittance area C, for example, blocking the light transmission of the camera.

The electrostatic discharge circuit is mainly used for discharging static electricity which may be generated in the display panel and protecting devices in the display panel from being damaged by the static electricity.
The bonding process of the integrated circuit and the first substrate can adopt COF (Chip On Flex, or, Chip On Film) or COG (Chip On glass) or COP (Chip On Panel) and other bonding processes, wherein the COF or COP bonding process is adopted to realize the bonding of the integrated circuit, so that the area occupied by the step area can be reduced, and the screen occupation ratio of the display panel is improved; referring to fig. 15, fig. 15 is a schematic cross-sectional structure diagram of a step region of a display panel when a driver circuit is bonded by a COF bonding process, and as can be seen from fig. 15, the driver circuit 710 is disposed on the flexible circuit board 700, and is electrically connected to a pad 610 disposed on the step region of the first substrate 010 of the array substrate through the flexible circuit board 700, and the flexible circuit board 700 can be bent to be disposed on a side of the step region away from the opposite substrate 02, so as to reduce an area of the step region.
