In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
For better understanding of the present invention, the following description is made in detail with reference to fig. 1 to 15 for a display panel and a display device according to an embodiment of the present invention.
Referring to fig. 1 to fig. 3, an embodiment of the invention provides a display panel 100, including: an array substrate 1; the pixel definition layer 2 is arranged on one side of the array substrate 1; the support 3 is arranged on one side, away from the array substrate 1, of the pixel definition layer 2, the support 3 comprises a first surface and a second surface which are arranged oppositely, the second surface, away from the pixel definition layer 2, comprises a flat portion 31 and a protruding portion 32 which extends in the direction away from the pixel definition layer 2 relative to the flat portion 31; a cathode layer 4 at least partially covering the second surfaces of the pixel defining layer 2 and the support 3; the shielding part 5 is arranged on one side of the cathode layer 4, which is far away from the array substrate 1, and the orthographic projection of the shielding part 5 on the array substrate 1 at least covers part of the orthographic projection of the protruding part 32 on the array substrate 1.
The display panel 100 provided by the embodiment of the invention includes an array substrate 1, a pixel defining layer 2, a support 3, a cathode layer 4 and a shielding portion 5, wherein the support 3 includes a first surface and a second surface which are opposite to each other, and is affected by a manufacturing process, the support 3 is provided with a flat portion 31 on the surface away from the second surface and a protruding portion 32 extending in a direction away from the pixel defining layer 2 relative to the flat portion 31, that is, the protruding portion 32 is higher than the flat portion 31, and the cathode layer 4 at least partially covers the second surfaces of the pixel defining layer 2 and the support 3, due to the effect of the protruding portion 32, a part of the cathode layer 4 on the protruding portion 32 also protrudes upwards, in a process of attaching the display panel 100, the support 3 is affected by an external force, and a part of the cathode layer 4 on the protruding portion 32 is easily damaged due to an excessive force, thereby causing a difference in the degree of reflection of the cathode layer 4, so that a problem of defective black spots was observed upon visual observation. In order to avoid the above problem, in the display panel 100 provided in the embodiment of the present invention, the shielding portion 5 is disposed on a side of the cathode layer 4 away from the array substrate 1, and an orthographic projection of the shielding portion 5 on the array substrate 1 at least partially covers an orthographic projection of the protruding portion 32 on the array substrate 1, that is, the shielding portion 5 shields a portion of the cathode layer 4 damaged by the supporting member 3, so as to reduce a probability that a black spot at a damaged position is observed by a user, and improve a product yield and user experience.
It should be noted that the support 3 and the pixel defining layer 2 may be of an integral structure, that is, the support 3 and the pixel defining layer 2 are made of the same material, so as to reduce the production cost. Alternatively, the support 3 and the pixel defining layer 2 may be formed by two processes, respectively, so as to improve the forming accuracy of the pixel defining layer 2 and the support 3. Optionally, the first surface of the support 3 is in contact with the pixel definition layer 2, that is, the support 3 is disposed on a surface of the pixel definition layer 2 facing away from the array substrate 1.
It is understood that the cathode layer 4 may cover the whole second surface of the pixel defining layer 2 and the support 3, or only partially cover the cathode layer 4 in an area where the light transmittance requirement of the display panel 100 is high, for example, an area where the under-screen camera is disposed, so as to improve the light transmittance.
Since the shielding portion 5 needs to shield the protruding portion 32 to prevent the black spot at the damaged position of the cathode layer 4 from being observed by the user, the shielding portion 5 may specifically adopt opaque materials such as metal and ink layer to improve the shielding effect.
Referring to fig. 4, in some optional embodiments, the display device further includes a touch layer 6 disposed on a side of the cathode layer 4 away from the array substrate 1, the touch layer 6 includes a touch electrode 611, and the shielding portion 5 and the touch electrode 611 are disposed at the same layer.
Specifically, in the present embodiment, the material of the touch layer 6 includes metal. Compared with the prior art that the touch layer 6 is made of ITO (Indium tin oxide), the sheet resistance of the metal material is smaller than that of ITO, and the touch signal transmission effect is good. In addition, from the aspect of the preparation process, the difficulty of hollowing the metal material is lower than that of hollowing the ITO, so that the difficulty of the preparation process is reduced. In this embodiment, the material of the touch layer 6 preferably adopts molybdenum with small surface resistance and good oxidation resistance. In practical implementation, the touch layer 6 may be made of other metals, such as aluminum Al, etc., but considering that the aluminum material has poor oxidation resistance, a corresponding inorganic protective layer, such as silicon oxide SiOx, etc., needs to be added.
It should be noted that the shielding portion 5 and the touch electrode 611 are disposed on the same layer, on one hand, it can be understood that the shielding portion 5 and the touch electrode 611 are formed through different processes, specifically, the shielding portion 5 and the touch electrode 611 are formed through two processes, the shielding portion 5 and the touch electrode 611 are made of different materials, and since the shielding portion 5 and the touch electrode 611 are disposed on the same layer, the film layer preparation sequence and the process of the existing film layers such as the array substrate 1 and the pixel defining layer 2 are slightly affected, and the preparation is convenient. On the other hand, the shielding portion 5 and the touch electrode 611 are formed by the same process, that is, the shielding portion 5 and the touch electrode 611 are made of the same material, for example, molybdenum, aluminum, titanium aluminum titanium, and other metals, so as to improve the production efficiency and reduce the production cost.
Referring to fig. 2, the pixel defining layer 2 includes an opening region and a non-opening region, the opening region is used for light emission display generated by the light emitting unit formed by the anode layer 21, the light emitting layer 22 and the cathode layer 4, the touch electrode 611 and the supporting member 3 are both disposed in the non-opening region to prevent the supporting member 3 from affecting the light emission of the light emitting unit, and therefore, the shielding portion 5 is also disposed in the non-opening region. Optionally, the shielding portion 5 is connected to the touch electrode 611, so that the forming is convenient, the shielding portion 5 and the touch electrode 611 can also be arranged at intervals, the shielding portion 5 is formed separately, and adverse effects of the shielding portion 5 on the touch performance are avoided.
Referring to fig. 2 to 5, in some alternative embodiments, the liquid crystal display device further includes a package glass 7, the package glass 7 is disposed on a side of the cathode layer 4 away from the array substrate 1, and the touch layer 6 is disposed on a surface of the package glass 7 away from the cathode layer 4; alternatively, the touch layer 6 is disposed on a surface of the encapsulation glass 7 facing the cathode layer 4.
Referring to fig. 5, it can be understood that the encapsulation glass 7 is disposed on a side of the cathode layer 4 away from the array substrate 1, and when the encapsulation glass 7 is formed, the encapsulation glass 7 is attached to a side of the second surface of the support 3, and the encapsulation glass 7 has excellent chemical stability, oxidation resistance, electrical insulation, flatness and compactness, and can effectively prevent water vapor from entering the light emitting layer 22, the thin film transistor T1, and other elements inside the display panel 100, which are easily damaged by corrosion. The sealing glass 7 has high hardness and is not easy to bend, so the sealing glass 7 is generally applied to a hard screen display panel. Optionally, the touch layer 6 is arranged On a side surface of the encapsulation glass 7 departing from the cathode layer 4, namely, in an On-cell structure, and film layer structures such as a polarizer, optical cement and a cover plate are sequentially stacked On a side surface of the touch layer 6 departing from the cathode layer 4, so that the touch layer 6 is closer to a touch position of a user On the cover plate, and the touch sensitivity is improved.
Referring to fig. 2, In another embodiment, the touch layer 6 is disposed on a surface of the encapsulation glass 7 facing the cathode layer 4, that is, the touch layer 6 is covered and protected by the encapsulation glass 7, so as to prevent the touch layer 6 from being affected by adverse factors such as moisture erosion, that is, the structural form of In-cell. When the touch layer 6 is set to be in-cell structure, in order to prevent the touch layer 6 from being electrically conductive in contact with the cathode layer 4, a first insulating layer 8 is disposed on a side of the touch layer 6 opposite to the encapsulation glass 7, that is, the first insulating layer 8 is disposed between the touch layer 6 and the cathode layer 4, so as to ensure the function of the touch layer 6.
Referring to fig. 6, in some optional embodiments, the touch layer 6 includes a touch electrode layer 61 and a bridging connection layer 62, which are stacked, the bridging connection layer 62 is disposed on a side of the touch electrode layer 61 away from the array substrate 1, and the shielding portion 5 is disposed on the touch electrode layer 61.
It should be noted that, because the bridging connection layer 62 is disposed on the side of the touch electrode layer 61 away from the array substrate 1, the touch electrode layer 61 is closer to the light emitting unit than the bridging connection layer 62, the shielding portion 5 is disposed on the touch electrode layer 61, the optical path from the light emitted from the light emitting unit to the shielding portion 5 is relatively short, and the offset of the light with respect to the emitting position is relatively small, so that the light blocked by the shielding portion 5 can be effectively reduced by disposing the shielding portion 5 on the touch electrode layer 61, and the light transmittance of the display panel 100 is improved.
Further, the touch layer 6 further includes a second insulating layer 63, the second insulating layer 63 is disposed between the touch electrode layer 61 and the bridge-crossing connection layer 62, the second insulating layer 63 is provided with a plurality of via holes at intervals, and an electrode on the bridge-crossing connection layer 62 is connected to the touch electrode layer 61 through the via hole on the second insulating layer 63, so that the touch electrode layer 61 and the bridge-crossing connection layer 62 are electrically connected.
Referring to fig. 7 to 11, in some alternative embodiments, a ratio of a length of an orthographic projection of the supporting member 3 on the array substrate 1 along the first direction X to a length of the orthographic projection along the second direction Y is 0.8 to 1.2, the protruding portions 32 are respectively located at corners of the supporting member 3, and the first direction X is perpendicular to the second direction Y.
It should be noted that, due to the limitation of the molding process of the support 3, when the difference between the ratio of the length of the orthographic projection of the support 3 on the array substrate 1 along the first direction X to the length of the orthographic projection along the second direction Y is relatively small, the protrusions 32 are respectively formed at the corner positions of the support. Specifically, the inventor has found through analysis that, since the material used for the supporting member 3 is an organic material, the basic process flow thereof includes coating, photolithography, developing, prebaking, baking, and the like, before prebaking, even baking, the supporting member 3 has a certain fluidity, and therefore, after forming, since the difference between the ratio of the length of the orthographic projection of the supporting member 3 on the array substrate 1 along the first direction X to the length along the second direction Y is relatively small, the top area of the supporting member 3 is large, and a portion of a plane with a large area is arranged in the middle, after curing, the middle plane portion is slightly sunken, and a high-edge and short-middle morphology is formed, and the above conclusion is verified through experimental and practical tests, specifically referring to fig. 7, a circled portion in the figure, i.e. a damaged portion of the cathode layer 4, a protruding portion 32 is formed at the corner portion of the supporting member 3 protruding relative to the middle portion, the cathode layer 4 located at the corner portions is more easily damaged by the pressure to cause the generation of black dots. Therefore, the shielding portion 5 is required to be disposed corresponding to each corner of the supporting member 3 in this embodiment, so that shielding is achieved and interference to the touch electrode load is avoided.
Specifically, when the ratio of the length of the orthogonal projection of the support 3 on the array substrate 1 along the first direction X to the length of the orthogonal projection along the second direction Y is 1 and the orthogonal projection is a quadrangle, the orthogonal projection of the support 3 on the array substrate 1 is a square, and the protrusions 32 are formed at four corners of the square. Therefore, the shielding portion 5 needs to be disposed corresponding to each corner of the supporting member 3, so that the shielding portion 5 can shield the protruding portion 32, and the problem of visible black spots caused by the cathode layer 4 covering the protruding portion 32 being damaged due to pressure is avoided.
Referring to fig. 7 to 11, in order to enable the shielding portion 5 to effectively shield each of the protruding portions 32 located at the corners of the supporting member 3, in some alternative embodiments, the shielding portion 5 includes a plurality of sub-shielding portions 51, and the orthographic projection of each sub-shielding portion 51 on the array substrate 1 covers the orthographic projection of each of the protruding portions 32 located at the corners of the supporting member 3 on the array substrate 1.
It can be understood that the orthographic projections of the sub-shielding parts 51 on the array substrate 1 respectively cover the orthographic projections of the convex parts 32 at the corners of the supporting member 3 on the array substrate 1. Specifically, each sub-shielding portion 51 may have the same size as the protruding portion 32, one sub-shielding portion 51 just shields the protruding portion 32 of one support member, and each sub-shielding portion 51 may also be larger than the protruding portion 32, so as to leave a margin for the alignment error or the size error between the sub-shielding portion 51 and the protruding portion 32, and ensure that the sub-shielding portion 51 can effectively shield the protruding portion 32 and the cathode layer 4 covering the protruding portion 32.
In some alternative embodiments, the sub-shielding portions 51 corresponding to the same support member 3 are disposed at intervals or continuously.
It can be understood that when the sub-shielding portions 51 are disposed at intervals, the space occupied by each sub-shielding portion 51 is relatively small, so that the light emitting amount of the light emitting element is shielded less, and the transmittance of the display panel 100 is not greatly affected, specifically, according to the shape of each protruding portion 32, each sub-shielding portion 51 may correspondingly adopt a rectangular shape, a triangular shape, a circular shape, or an irregular shape, as long as the orthographic projection of the sub-shielding portion 51 on the array substrate 1 can respectively cover the orthographic projection of the protruding portions 32 at the corners of the supporting member 3 on the array substrate 1. When the sub shielding portions 51 are continuously arranged, the sub shielding portions 51 corresponding to the same supporting member 3 can be integrally formed through processes such as evaporation and etching, and each sub shielding portion 51 does not need to be formed independently, so that the process is simpler and more convenient, and meanwhile, the structural stability of each sub shielding portion 51 is better when the sub shielding portions 51 are continuously arranged, the position change is not easy to occur, and the alignment precision between each sub shielding portion 51 and the protruding portion 32 is ensured. Specifically, each sub-shielding portion 51 corresponding to the same supporting member 3 may be formed in an "X" shape, a cross shape, etc., as required, depending on the position of the protruding portion 32 on the supporting member 3.
Referring to fig. 4, optionally, the touch electrodes 611 are disposed in a grid shape, and the touch electrodes 611 are generally disposed in the non-opening areas between the opening areas, so as to avoid the influence on the light emitted from the light emitting units, ensure that the display panel 100 has better light transmittance, and enable the display panel 100 to have better display effect.
Further, the touch electrode 611 includes: the first routing wires extend along a first direction X and the second routing wires extend along a second direction Y; the first direction X and the second direction Y are crossed with each other; the plurality of first traces and the plurality of second traces are located in the non-opening area between the opening areas.
The touch electrode 611 is set to be a plurality of first wires extending along the first direction X and second wires extending along the second direction Y, so that the first wires and the second wires can be disposed in the non-opening area, and thus, the light emitted from the opening area is not shielded by the graph of the touch electrode 611, the light transmittance of the display panel 100 is not affected, and the display panel 100 has a better display effect. Optionally, the shielding portion 5 is connected to the grid of the touch electrode 611 corresponding to the support 3, and the shielding portion 5 can be connected to at least one of the first trace and the second trace, for example, when each sub-shielding portion 51 can form an "X" shape, each sub-shielding portion 51 can be connected to an intersection point of the first trace and the second trace, that is, connected to a vertex of the grid-shaped touch electrode 611.
Referring to fig. 12 to 15, in some alternative embodiments, a ratio of a length of an orthographic projection of the supporting member 3 on the array substrate 1 along the first direction X to a length of the supporting member along the second direction Y is 1.5 to 2.5, the protruding portion 32 is located in a middle portion of the supporting member 3, the orthographic projection of the shielding portion 5 on the array substrate 1 covers the orthographic projection of the protruding portion 32 on the array substrate 1, and the first direction X is perpendicular to the second direction Y.
It can be understood that, the ratio of the length of the orthographic projection of the supporting member 3 on the array substrate 1 along the first direction X to the length of the support member 3 along the second direction Y is 1.5-2.5, that is, the orthographic projection of the supporting member 3 on the array substrate 1 is in the shape of a long strip, the inventor found through analysis that after the supporting member 3 is formed, since the ratio of the length of the orthographic projection of the supporting member 3 on the array substrate 1 along the first direction X to the length of the orthographic projection along the second direction Y is 1.5-2.5, the long strip is formed, the top of the long strip supporting member 3 is in the shape of a long strip, the area of a plane is small, after curing, the plane is in the shape of a circular arc, the top of the whole supporting member 3 is in the middle-high edge short distribution, and the above conclusion is verified through experimental practical tests, specifically referring to fig. 12, a circled part in the figure, that the damaged part of the cathode layer 4, therefore, the shielding part 5 adopted in this embodiment needs to be arranged corresponding to the middle part of the supporting member 3, the shielding is realized, and the interference to the touch electrode load is avoided.
Specifically, the orthographic projection of the shielding portion 5 on the array substrate 1 can be in a shape of rectangle, ellipse, etc., and in order to correspond to the protruding portion 32 located in the middle of the supporting member 3, the shielding portion 5 generally adopts an integral structure, so that the shielding portion 5 can shield more protruding portions 32 in the middle of the supporting member 3, and it is avoided that part of the protruding portions 32 are not shielded by the shielding portion 5, so that black dots are generated, and the display effect of the display panel 100 is affected.
In some alternative embodiments, the orthographic projection width of the shielding part 5 on the array substrate 1 is 0.5 μm to 2.0 μm. It can be understood that the orthographic projection width of the shielding portion 5 on the array substrate 1 should not be too large, and too large will affect the light emitting effect of the light emitting unit, and the orthographic projection width of the shielding portion 5 on the array substrate 1 should not be too small, and too small cannot well shield the protruding portion 32.
