Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
One embodiment of the present invention relates to a display panel. The specific structure is shown in fig. 1, and comprises: the display device comprises a substrate 10, a display layer 20 and a touch layer 30, wherein the display layer 20 and the touch layer 30 are arranged on one side of the substrate 10. The display layer 20 includes a plurality of first electrodes 21 arranged at intervals, and the first electrodes 21 include a light emitting region 211 and a non-light emitting region 212 adjacent to the light emitting region 211. Specifically, in this embodiment, the first electrode 21 is an anode, the display layer 20 includes an anode 21 and a pixel defining layer 22 disposed to cover the anode 21, an opening 23 is disposed on the pixel defining layer 22, an area where the opening 23 falls on the anode 21 is a light emitting area 211 of the anode 21, and the other area where the anode 21 is covered by the pixel defining layer 22 is a non-light emitting area 212. In addition, the touch panel further includes a light emitting material layer 24 disposed in the opening 23, a cathode 25 covering the light emitting material layer 24, and a film encapsulation layer 26 covering the cathode 25 and the pixel defining layer 22, and the touch layer 30 is disposed on the film encapsulation layer 26. The light emitting material layer 24 emits light by an electric charge between the anode 21 and the cathode 25. It should be understood that the touch layer 30 is disposed on the film encapsulation layer 26 only by way of specific example in this embodiment, and is not limited thereto, and in other embodiments of the present invention, a buffer layer or the like may be disposed between the touch layer 30 and the film encapsulation layer 26, which is not specifically illustrated in this embodiment. The touch layer 30 includes a touch electrode 31, and an orthogonal projection (X region in fig. 1) of the touch electrode 31 on the substrate 10 covers an orthogonal projection (Y region in fig. 1) of the non-light emitting region 212 of the first electrode 21 on the substrate 10.
Compared with the prior art, the orthographic projection of the non-light-emitting area 212 of the first electrode 21 on the substrate 10 is covered by the orthographic projection of the touch electrode 31 on the substrate 10, so that the shielding of at least part of the touch electrode 31 on the external light and the shielding of the non-light-emitting area 212 of the first electrode 21 on the external wiring are in the same area, namely, the shielding of at least part of the touch electrode 31 on the external light and the shielding of the non-light-emitting area 212 of the first electrode 21 on the external light coincide, thereby reducing the shielding of the touch electrode 31 on the external light and improving the transmittance of the display panel.
Specifically, as shown in fig. 1, in the present embodiment, the orthographic projection of the touch electrode 31 on the substrate 10 falls within the orthographic projection of the non-light-emitting region 212 of the first electrode 21 on the substrate 10. With such an arrangement, the light-shielding region of the touch electrode 10 can completely fall into the light-shielding region of the non-light-emitting region 212 of the first electrode 21, that is, all incident lights shielded by the touch electrode 10 are incident lights shielded by the non-light-emitting region 212 of the first electrode 21, so that the touch electrode 10 cannot cause extra light shielding, thereby eliminating shielding of the touch electrode 31 on the incident lights and greatly improving transmittance of the display panel.
In another embodiment of the present invention, as shown in fig. 2, the orthographic projection of the non-light-emitting area 212 of the first electrode 21 on the substrate 10 falls within the orthographic projection of the touch electrode 31 on the substrate 10, so that the area of the touch electrode 31 can be set to be larger, the touch effect can be improved, and at the same time, the light-shielding area of the non-light-emitting area 212 of the first electrode 21 can be fully utilized, that is, the transmittance of the display panel can be improved to the maximum extent while the touch effect is ensured. In other embodiments of the present invention, the orthogonal projection of the non-light-emitting region 212 of the first electrode 21 on the substrate 10 and the orthogonal projection of the touch electrode 31 on the substrate 10 may be alternately disposed, and there are other cases such as a certain overlapping area.
In one embodiment of the present invention, as shown in fig. 3, an orthogonal projection of the touch electrode 31 on the substrate 10 is annular, and the annular orthogonal projection is disposed outside an orthogonal projection of the light emitting region 211 of the first electrode 21 on the substrate 10. Specifically, in practical applications, the non-light-emitting region 212 of the first electrode 21 is a process margin reserved for the light-emitting region 211, and the light-emitting region 211 is located at a middle portion of the first electrode 21, so that the non-light-emitting region 212 formed by the light-emitting region 211 and the edge of the first electrode 21 at an interval is a generally annular region. Therefore, in the present embodiment, the light blocking region of the non-light emitting region 212 can be effectively used by setting the orthographic projection of the touch electrode 31 on the substrate to be annular, which is convenient for increasing the area of the touch electrode 31.
In other embodiments of the present application, the orthographic projection of the touch electrode 31 on the substrate 10 may be an annular shape formed by sleeving a square, a circle, a polygon, a rounded rectangle, and other figures, and specifically, the touch electrode may be flexibly configured according to actual needs.
In one embodiment of the present invention, as shown in fig. 4, which is a partial enlarged view of a partial area in a display panel provided in one embodiment of the present invention, the touch layer 30 includes a first touch electrode 32 and a second touch electrode 33 that are disposed in an insulated manner, the first touch electrode 32 extends along a first direction (a direction in fig. 4), the second touch electrode 33 extends along a second direction (B direction in fig. 4), and the first direction intersects the second direction. In the present embodiment, the first touch electrode 32 and the second touch electrode 33 are located on the same layer, and the intersecting position (position C in fig. 4) of the first touch electrode 32 and the second touch electrode 33 is insulated by a bridging manner. The bridging method is to arrange a portion of the second touch electrode 33 at the intersection of the first touch electrode 32 and the second touch electrode 33 and the first touch electrode 32 as different layers, and to arrange an insulating layer between the second touch electrode 33 and the first touch electrode 32 to ensure that the second touch electrode 33 and the first touch electrode 32 are arranged as an insulating layer.
It is understood that the aforementioned insulating arrangement of the intersecting position of the first touch electrode 32 and the second touch electrode 33 by the bridge connection method is merely an example of a specific structure in this embodiment, and is not limited thereto, and in other embodiments of the present invention, other structures may also be adopted, for example, the first touch electrode 32 and the second touch electrode 33 are arranged on different layers, so as to ensure that the second touch electrode 33 and the first touch electrode 32 are arranged in an insulating manner, and the like, and the specific arrangement may be flexibly set according to actual needs.
Specifically, in the present embodiment, the first touch electrode 32 is a touch sensing electrode, and the second touch electrode 33 is a touch driving electrode. It is understood that, in other embodiments of the present invention, the second touch electrode 33 may be a touch sensing electrode, and the first touch electrode 32 may be a touch driving electrode, which may be flexibly configured according to actual needs.
In one embodiment of the invention, as shown in fig. 5, the number of the first touch electrodes 32 is multiple, the number of the second touch electrodes 33 is multiple, the touch layer 30 further includes a plurality of first connection lines 34 and a plurality of second connection lines 35, the first connection lines 34 connect two adjacent first touch electrodes 32, and the second connection lines 35 connect two adjacent second touch electrodes 33. In the second direction, one first touch electrode 32 is disposed between two adjacent second touch electrodes 33. The second connection line 35 includes a bridge region 351, and an insulation layer 40 is disposed between the bridge region 351 and the first connection line 34 to be insulated from the first connection line 34.
An orthogonal projection of the bridging region 351 on the substrate 10 covers an orthogonal projection of the non-light emitting region 212 of the first electrode 21 on the substrate 10. The orthographic projection of the bridging region 351 on the substrate 10 is arranged to cover the orthographic projection of the non-light-emitting region 212 of the first electrode 21 on the substrate 10, so that the light-shielding area of the bridging region 351 can be reduced, and the transmittance of the display panel is further improved.
Specifically, in the present embodiment, as shown in fig. 6, an orthogonal projection of the bridging region 351 on the substrate 10 (region C in fig. 6) is within an orthogonal projection of the non-light emitting region 212 of the first electrode 21 on the substrate 10 (region D in fig. 6). With this arrangement, it is ensured that the light-shielding region of the bridging region 351 is entirely within the light-shielding region of the non-light-emitting region 212 of the first electrode 21, and the bridging region 351 is ensured not to shield incident light. It should be understood that the foregoing is merely an illustration of a specific structure of the bridging region 351 in this embodiment, and is not a limitation, and in other embodiments of the present invention, other structures may be adopted, such as a partial overlap between an orthogonal projection of the bridging region 351 on the substrate 10 and an orthogonal projection of the non-light emitting region 212 of the first electrode 21 on the substrate 10, and the like, and the arrangement may be flexibly set according to actual needs.
In one embodiment of the present invention, as shown in fig. 7, an orthogonal projection of the bridging region 351 on the substrate 10 falls within an orthogonal projection of the first touch electrode 32 on the substrate 10. The orthographic projection of the bridging area 351 on the substrate 10 is set to fall in the orthographic projection of the first touch electrode 32 on the substrate 10, namely the bridging area 351 and the first touch electrode 32 are opposite to each other and opposite to each other to form mutual capacitance, when a user presses a finger, the relative distance between the bridging area 351 and the first touch electrode 32 is reduced, the capacitance value of the capacitance is changed, and therefore a touch signal is generated.
Preferably, in an embodiment of the present invention, as shown in fig. 8, an orthogonal projection of the bridging region 351 on the substrate 10 coincides with an orthogonal projection of the first touch electrode 32 on the substrate 10. The orthographic projection of the bridging area 351 on the substrate 10 is overlapped with the orthographic projection of the first touch electrode 32 on the substrate 10, so that the relative area between the bridging area 351 and the first touch electrode 32 can be increased, the capacitance value of the mutual capacitance is increased, the change range of the capacitance value is also increased, the touch sensing capability is also improved, and the touch sensing effect of multi-point touch is improved.
In addition, in order to avoid the influence of the bridge region 351 on the light emission of the light emitting region 211, in this embodiment, the trace shape of the bridge region 351 may be correspondingly designed according to the arrangement position of the bridge region 351, for example, as shown in fig. 9, when the arrangement position of the bridge region 351 does not influence the light emission of the light emitting region 211, the bridge region 351 may be arranged in a linear trace design, and as shown in fig. 10, as the trace position of the bridge region 351 may influence the light emission of the light emitting region 211, the bridge region 351 is arranged as a bent trace, thereby avoiding influencing the light emission of the light emitting region 211, and particularly, the bridge region 351 may be flexibly arranged according to actual needs.
In addition, in one embodiment of the present invention, the orthographic projection of the bridging regions 351 located in the same row on the substrate 10 falls on the same side of the orthographic projection of the light emitting region 211 of the anode 21 on the substrate 10. Since the light emitting region 211 is disposed in the middle of the non-light emitting region 22, in order to avoid the bridge regions 351 affecting the light emission of the light emitting region 211, the bridge regions 351 need to be disposed on either side of the light emitting region 211 to bypass the region where the light emitting region 211 is located, in this embodiment, the orthographic projection of the bridge regions 351 located in the same row on the substrate 10 is located on the same side of the orthographic projection of the light emitting region 211 of the anode 21 on the substrate 10, that is, as shown in fig. 11, the bridge regions 351 located in the same row are located on the same side of the light emitting regions 211. The interference to the transmission of the touch signal caused by the too close distance between two adjacent bridging regions 351 is avoided.
An embodiment of the invention further provides a display panel, as shown in fig. 12, including a transparent light emitting area 100 and a non-transparent light emitting area 200 adjacent to the transparent light emitting area 100, the display substrate 300 provided in the foregoing embodiment is disposed in the transparent light emitting area 100, and another kind of display substrate is disposed in the non-transparent light emitting area 200. It should be understood that the foregoing is only a specific example in the embodiments of the present invention, and is not limited thereto, and in other embodiments of the present invention, the display panel may only include the transparent light emitting area 100, and all of the transparent light emitting areas 100 may be provided with the structure of the display substrate 300 and the like as provided in the foregoing embodiments.
Compared with the prior art, in the present embodiment, the display substrate 300 provided in the foregoing embodiment is disposed in the transparent light emitting area 100, so that the technical effects of the foregoing embodiments are also achieved, and no further description is provided herein.
It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific examples for carrying out the invention, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention in practice.
