Detailed Description
In order to further describe the technical means and effects adopted by the invention to achieve the preset aim, the following detailed description refers to the specific implementation, structure, characteristics and effects of a display panel and an electronic device according to the invention with reference to the accompanying drawings and preferred embodiments. In the following description, different "an embodiment" or "an embodiment" do not necessarily refer to the same embodiment. Furthermore, the particular features, structures, or characteristics of one or more embodiments may be combined in any suitable manner.
The technical scheme of the embodiment of the invention aims to solve the technical problems, and the overall thought is as follows:
Example 1
Referring to fig. 1 and 3, a display panel provided in an embodiment of the present invention includes a display area A-A and a frame area B-B disposed at two opposite edges of the display area A-A, the display area A-A includes a cathode layer 6, the cathode layer 6 has an extraction portion 62, the extraction portion 62 extends to the frame area B-B, and the frame area B-B is electrically connected to the extraction portion 62 for transmitting an electrical signal of a driving IC1 to the display area A-A; wherein the frame area B-B comprises a substrate 2, a transmission layer 3, an insulating layer 4, a first electrode layer 5 and a lead-out part 62 which are arranged in a stacked manner;
the side of the first electrode layer 5 facing the lead-out portion 62 has a first non-planar surface;
The side of the lead-out portion 62 facing the first electrode layer 5 has a second non-planar surface adapted to the first non-planar surface, and the second non-planar surface and the first non-planar surface are attached to each other.
Specifically, in order to solve the problem that for a narrow-frame display device, after the frame area is narrowed, the width of the switching area of the anode and the cathode for transmitting electric signals in the frame area is also reduced, so that the contact area of two metal layers is reduced, and larger current cannot be transmitted, and the display effect is affected.
The display panel is an OLED display panel, and includes the display area A-A and a frame area B-B disposed at two opposite edges of the display area A-A, where the frame area B-B is usually disposed at the left and right sides of the display area A-A, the frame area B-B is set as a switching area, and switches the electric signal of the driving IC1 to the cathode layer 6 of the display area A-A, the display area A-A is sequentially provided with a TFT substrate 11 and a pixel defining layer 10 from the substrate 2 upwards, and the cathode layer 6 is disposed on the upper side of the pixel defining layer 10.
Wherein the frame area B-B is formed by sequentially stacking the substrate 2, the transmission layer 3, the insulating layer 4, the first electrode layer 5 and the lead-out portion 62 from bottom to top, so as to form a complete transmission area structure, and the transmission layer 3 transmits the electric signal of the driving IC1 to the cathode layer 6 of the display area A-A through the first electrode layer 5 and the lead-out portion 62; the substrate 2 is a glass substrate, and the display area A-A and the frame area B-B share the same substrate 3; the transmission layer 3 is made of metal, and the transmission layer 3 and the first electrode layer 5 can be electrically connected across the insulation layer 4 through a via hole, a winding or the insulation layer 4 and the like; the lead-out portion 62 is electrically connected to the cathode layer 6 of the display area A-A, and is used for transmitting the electric signal of the driving IC1 to the cathode layer 6, in this embodiment, the lead-out portion 62 is disposed in the same layer as the cathode layer 6 of the display area A-A, that is, the lead-out portion 62 as a part of the cathode layer 6 of the display area A-A overlaps with the first electrode layer 5 in the frame area B-B, and is used for receiving the electric signal of the driving IC 1; the first electrode layer 5 and the lead-out portion 62 are overlapped with each other, so that the lead-out portion 5 needs to have good electrical conductivity, and the anode and the lead-out portion 62 serving as the cathode layer 6 are overlapped with each other and transmit an electrical signal thereto, and the material of the anode is designed according to experience or actual needs of those skilled in the art, and is not an important point of protection of the present application, so that redundant description is not made here.
Wherein, a side of the first electrode layer 5 facing the lead-out portion 62 has a first non-plane, a side of the lead-out portion 62 facing the first electrode layer 5 has a second non-plane adapted to the first non-plane, so it can be understood that, referring to fig. 1, a position where the first electrode layer 5 overlaps the lead-out portion 62 is the first non-plane, the rest is a planar surface, a position where the lead-out portion 62 overlaps the first electrode layer 5 is the second non-plane, and the rest is a planar surface, where the rest is the display area A-A is still a planar surface; the first non-planar surface and the second non-planar surface may be an arc-shaped surface-adapted attachment, a wave-shaped surface-adapted attachment, or a groove-tooth embedded engagement-type attachment, so long as the contact area between the first electrode layer 5 and the lead-out portion 62 can be increased, as long as the first non-planar surface and the second non-planar surface are not laminated to each other; meanwhile, when the first electrode layer 5 and the lead-out portion 62 are overlapped with each other by the first non-planar surface and the second non-planar surface, even if the cathode layer 6 of the display area A-A is different in overlapping width of the frame areas B-B on both sides, the difference in contact area is not great because of non-planar contact, so that the problem of difference in current transmission of the frame areas B-B on both sides due to a slight deviation in overlapping of the cathode layer 6 of the display area A-A and the first electrode layer 5 of the frame areas B-B, that is, the anode, can be reduced.
According to the above-mentioned list, in the display panel provided by the application, the contact surface of the first electrode layer 5 and the lead-out part 62, which are used for transmitting electric signals, of the frame area B-B is set to be non-planar contact, and the contact area of the first electrode layer 5 and the lead-out part 62 is increased on the premise that the width of the frame area B-B is reduced, so that the purpose of reducing contact resistance and enabling the first electrode layer 5 and the lead-out part 62 to transmit larger current is achieved; meanwhile, the non-planar contact mode provided by the application can also reduce the problem of current transmission difference of the two side frame areas B-B caused by small deviation of the lap joint of the cathode layer 6 of the display area A-A and the first electrode layer 6 of the frame area B-B, namely the anode.
The term "and/or" is herein merely an association relation describing an associated object, meaning that there may be three relations, e.g. a and/or B, specifically understood as: the composition may contain both a and B, and may contain a alone or B alone, and any of the above three cases may be provided.
Further, referring to fig. 1 and fig. 3, in an embodiment of the present invention, the first non-plane includes a plurality of splice grooves 51, and the splice grooves 51 are spaced along a first direction a;
The second non-plane includes a plurality of splicing teeth 61, the plurality of splicing teeth are arranged at intervals along the first direction a, and the splicing teeth 61 are adapted to the splicing groove 51;
Wherein the first direction a is perpendicular to the lamination direction of the first electrode layer 5 and the lead-out portion 62.
Specifically, in order to achieve that the contact area between the first electrode layer 5 and the lead-out portion 62 can be increased as much as possible when the first non-plane and the second non-plane are fit and attached, in this embodiment, the first non-plane is set to include the surfaces of the plurality of spliced teeth 51, the second non-plane is set to be matched with the surfaces of the plurality of spliced teeth 61, the two surfaces form a contact manner of mutual embedded engagement, in the manufacturing process, the plurality of spliced grooves 51 can be formed only by mask plates and photolithography after the first electrode layer 5, that is, the anode, is prepared, and the preparation manner of the lead-out portion 62, that is, the cathode layer 6, is not changed, so that the setting manner of this embodiment is simple and effective; it will of course be appreciated that: it is obvious that the stacking direction of the first electrode layer 5 and the lead-out portion 62 is the thickness direction of the display panel, and the first direction a may be the width direction of the display panel or the length direction of the display panel in actual arrangement.
Wherein, the contact area of the anode and the cathode layer 6 in the frame area B-B in the prior art is originally S1, and after the width of the frame area B-B is reduced by L, the contact width of the anode and the cathode layer 6 is also reduced by L, the contact area is naturally reduced, and the contact resistance is naturally increased; in the display panel provided by the embodiment of the invention, even though the width of the frame area B-B is equal to the width of the frame area B-B reduced by L in the prior art, the contact area S2 can be larger than the contact area of the first electrode layer 5 (anode) and the lead-out portion 62 (cathode layer 6) after the width of the frame area B-B is reduced by L in the prior art by the adaptive bonding of the first non-planar surface and the second non-planar surface of the first electrode layer 5 (anode) and the lead-out portion 62 (cathode layer 6), and it is preferable to design S2 to be equal to S1 or even larger than S1, so that the large current transmission effect of the frame area B-B under the frame design is optimized; the technical effect that S2 is greater than or equal to S1 can be achieved by adjusting the dimensions of the splice groove 51 and the splice teeth 61, which is not difficult for those skilled in the art to understand or achieve, and is not limited herein too much.
Further, referring to fig. 2 and the accompanying drawings, in a display panel provided in an embodiment of the present invention, in a specific implementation, a slot size of the splice groove 51 is larger than a slot bottom size thereof.
Specifically, in order to achieve perfect fit between the splice groove 51 and the splice teeth 61, in this embodiment, the size of the notch of the splice groove 51 is set to be larger than the size of the bottom of the groove, because the extraction portion 62, that is, the cathode layer 6 is realized by vapor deposition during the preparation, so that if the size of the notch of the splice groove 51 is smaller than the size of the bottom of the groove, the problem that the extraction portion 62, that is, the cathode layer 6, may be left on the side wall of the splice groove is limited; in this embodiment, the slot opening of the splice slot 51 is set to be larger than the slot bottom thereof, for example: inverted trapezoids as shown in fig. 1 and 3.
Further, referring to fig. 2 and fig. 4, in a specific implementation, a front projection size of the lead-out portion 62 toward the substrate 2 is smaller than a front projection size of the first electrode layer 5 toward the substrate 2;
the substrate 2 is used for sharing the frame area B-B with the display area A-A.
Specifically, in order to avoid short-circuiting between the first electrode layer 5 and other electronic components around the lead-out portion 62, the orthographic projection dimension of the lead-out portion 62 toward the substrate 2 is set smaller than the orthographic projection dimension of the first electrode layer 5 toward the substrate 2 in this embodiment, that is, referring to fig. 1 and 3, the width of the lead-out portion 62 in the first direction a is smaller than the width of the first electrode layer 5 in the first direction a.
Further, referring to fig. 1 and fig. 3, in a specific implementation, the dimensions of the plurality of splice grooves 51 along the stacking direction of the first electrode layer 5 and the lead-out portion 62 are equal.
Specifically, in order to simplify the manufacturing process, in this embodiment, the dimensions of the plurality of splice grooves 51 along the stacking direction of the first electrode layer 5 and the lead-out portion 62 are set to be equal, that is, the groove depths of the plurality of splice grooves 51 are all equal, so that only one operation is required when the first electrode layer 5 is subjected to photolithography, and the manufacturing process can be simplified on the premise of ensuring that the plurality of splice grooves 51 are arranged, thereby reducing unnecessary costs.
Further, in an embodiment of the present invention, the dimensions of the plurality of splice grooves 51 along the first direction a are equal/unequal.
Specifically, in order to increase the contact area between the first electrode layer 5 and the lead-out portion 62 as much as possible, in this embodiment, the dimensions of the plurality of splice grooves 51 along the first direction a may be set to be equal or unequal, that is, the dimensions of the plurality of splice grooves 51 may be set to be equal or different, and how to set the plurality of splice grooves is completely dependent on the extent to which the contact area needs to be increased, and it is obvious that a person skilled in the art may design and adjust the dimensions according to needs or experience.
Further, in an embodiment of the present invention, the splice groove 51 is one or more of rectangular, trapezoidal, triangular, arc-shaped, and oval.
Specifically, the shapes of the splicing groove 51 and the splicing tooth 61 may be rectangular, trapezoidal, triangular, arc-shaped, oval, etc., or various shapes may exist at the same time, as long as the splicing groove 51 and the splicing tooth 61 can be fit, and the method is not limited in any way.
Further, referring to fig. 1 and 3, in a display panel provided in an embodiment of the present invention, in a specific implementation, a dimension of the splice groove 51 along a stacking direction of the first electrode layer 5 and the lead-out portion 62 is smaller than a dimension of the first electrode layer 5 along the stacking direction of the first electrode layer 5 and the lead-out portion 62;
The size of the splice teeth 61 in the lamination direction of the first electrode layer 5 and the lead-out portion 62 is smaller than the size of the lead-out portion 62 in the lamination direction of the first electrode layer 5 and the lead-out portion 62.
Specifically, in order to ensure the integrity of the first electrode layer 5 and the lead-out portion 62, in this embodiment, the dimension of the splice groove 51 in the stacking direction of the first electrode layer 5 and the lead-out portion 62 is smaller than the dimension of the first electrode layer 5 in the stacking direction of the first electrode layer 5 and the lead-out portion 62, that is, the groove depth of the splice groove 51 is smaller than the thickness of the first electrode layer 5; accordingly, the size of the teeth 61 in the lamination direction of the first electrode layer 5 and the lead-out portion 62 is smaller than the size of the lead-out portion 62 in the lamination direction of the first electrode layer 5 and the lead-out portion 62, that is, the height of the teeth 61 is smaller than the thickness of the lead-out portion 62.
Further, referring to fig. 1 and fig. 3, in a specific implementation of a display panel provided in an embodiment of the present invention, a side of the first electrode layer 5 facing away from the display area A-A completely wraps a side of the transmission layer 3 facing away from the display area A-A.
Specifically, in order to realize the electrical connection between the first electrode layer 5 and the transmission layer 3, in this embodiment, a side of the transmission layer 3 facing away from the display area A-A is completely included in the first electrode layer 5, so that the first electrode layer 5 may be directly electrically connected with the transmission layer 3 in a stacked manner, so as to quickly transfer the electrical signal of the driving IC1 to the first electrode layer 5 (anode) via the transmission layer 3, and then to the lead-out portion 62 (cathode layer 6).
Further, referring to fig. 1, fig. 2, fig. 3, and fig. 4, a display panel according to an embodiment of the present invention further includes a driving IC1 in a specific implementation;
