The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the technical solutions of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. 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.
As shown in fig. 1, an embodiment of the present invention provides an OLED display panel 1, which includes a substrate 2, a pixel defining layer 3 formed on a surface of the substrate 2, and a spacer layer 4 formed on a surface of the pixel defining layer 3. The pixel defining layer 3 divides the substrate 2 into a plurality of light emitting regions 21, wherein the pixel defining layer 3 surrounds each of the light emitting regions 21 such that the plurality of light emitting regions 21 are exposed to the pixel defining layer 3. The spacing layer 4 includes a plurality of mutually spaced convex pillars 41, and the plurality of convex pillars 41 are non-uniformly distributed on the substrate 2.
The substrate 2 may be a glass substrate or a flexible substrate.
In one embodiment, the light-emitting regions 21 may include a plurality of red light-emitting regions, a plurality of green light-emitting regions, and a plurality of blue light-emitting regions.
The pixel defining layer 3 may be formed by depositing a pixel defining layer material and etching the pixel defining layer material; the pixel defining layer may be made of a photoresist material formed by mixing a resin, a photosensitizer, a solvent, and the like.
In one embodiment, the spacing layer 4 is a plurality of mutually spaced apart pillars 41.
The material of the spacing layer 4 can be organic material or inorganic material; preferably, an organic material; more preferably, it is one or more of polyimide resin, polystyrene resin, polymethacrylic resin, silicone material, and the like.
In the embodiment of the technical scheme, the convex columns 41 can support the mask plate during evaporation to prevent the mask plate from contacting with the substrate 2, so that the friction between the mask plate and the substrate 2 can be reduced, and foreign matters on the metal mask plate can be prevented from being stuck to the substrate 2 through the contact between the mask plate and the substrate 2 to cause poor evaporation; in addition, during vapor deposition, if the foreign matters of the mask plate are bonded to the convex columns 41, the mask plate can be jacked up, so that local color mixing is caused, the foreign matters are bonded to the convex columns 41, so that packaging failure is caused, and the panel presents black points, namely although the convex columns 41 have the function of supporting the mask plate, if the density of the black points is too high, the risks of color mixing and black points caused by the foreign matters are higher; the inventor of the technical scheme discovers that foreign matters are bonded at different positions of the substrate, so that the severity of the evaporation color mixing and black dot consequences caused by the foreign matters is different, and a plurality of convex columns 41 are designed to be in non-uniform distribution, so that the density of the convex columns 41 at different positions of the substrate 2 can be set as required, and the effect of supporting the mask plate and the effect of preventing the color mixing and the black dots of the convex columns 41 can be considered.
In an embodiment, a plurality of pixel regions 22 (only one is shown in fig. 1) are defined on the substrate 2, each pixel region 22 corresponds to one pixel unit of the OLED display panel, and each pixel region 22 includes a plurality of light emitting regions 21; the ratio of the number of the convex columns 41 distributed on the substrate 2 to the number of the pixel regions 22 defined on the substrate ranges from 3:1 to 1: 50.
In an embodiment, a pitch between each adjacent pillars 41 distributed on the substrate 2 ranges from 10 micrometers to 1000 micrometers.
In the foregoing embodiment, the distribution density of the convex pillars 41 is small as a whole, so that the probability that the foreign matter of the mask plate is bonded to the convex pillars 41 can be reduced, and the risk of local color mixing and black spots can be reduced.
In an embodiment, each of the pixel regions 22 includes three light emitting regions 21, and the three light emitting regions 21 are a red light emitting region, a green light emitting region, and a blue light emitting region.
In an embodiment, the distribution density of the pillars 41 is different in at least two regions of the substrate 2. That is, the convex pillars 41 may be provided in different densities according to characteristics of different regions of the substrate 2. For example, as shown in fig. 2, the distribution density of the pillars 41 in the middle area 201 of the substrate 2 is less than the distribution density of the pillars 41 in the two end areas 202 of the substrate 2, so as to enhance the supporting effect of the two end areas 202 of the substrate 2 and reduce the probability of defects in the middle area 201 of the substrate 2 during evaporation.
In one embodiment, the distribution density of the pillars 41 is different along different directions of the substrate 2. Wherein, the distribution density of the convex columns 41 in different directions can be set according to the characteristics of the substrate 2. For example, the distribution density of the convex columns 41 is different in a direction along a stretching direction of the corresponding metal mask plate on the substrate 2 and in a direction along a non-stretching direction of the corresponding metal mask plate on the substrate 2.
Further, in an embodiment, the distribution density of the pillars 41 is different along different directions of the substrate 2, and the distribution density of the pillars 41 is the same along the same direction of the substrate 2.
At present, during vapor deposition, the metal mask plate is easy to wrinkle, and the area where the wrinkle is generated is easy to contact with the substrate 2, so that the series of defects are generated; therefore, the distribution density of the convex columns 41 cannot be too small on the substrate 2 corresponding to the area where the mask is prone to wrinkle. In an embodiment, the mask plate includes at least one wrinkle region, a spacing between each adjacent convex pillar 41 and the wrinkle region is defined as K, a half-wave width of a wrinkle of the wrinkle region is L, a height of the wrinkle is H, and a thickness of the spacer layer is a, where K is smaller than L × a/H; that is to say, the distance between the convex columns 41 and the wrinkle region is smaller than L × a/H, so as to ensure that the distribution density of the convex columns 41 in the wrinkle region is not too small, and the mask plate can be supported, so that the wrinkles in the wrinkle region of the mask plate have a distance from the substrate 2, thereby preventing the wrinkles in the wrinkle region of the mask plate from contacting the substrate 2 during evaporation.

In the embodiment, the folding direction is defined as an X direction, and a direction perpendicular to the X direction is defined as a Y direction.

In this embodiment, in the panel region 12, the convex columns 41 are uniformly distributed along the Y direction and also uniformly distributed along the X direction.
The folding area 11 of the foldable panel has higher sensitivity to foreign matters, that is, if the foreign matters on the mask plate corresponding to the folding area 11 stick to the convex columns 41 during vapor deposition, the yield of the panel is greatly influenced; therefore, in the present embodiment, the overall distribution density of the convex columns 41 in the folding area 11 is less than the overall distribution density of the panel area 12, so as to reduce the probability that foreign matters on the mask plate adhere to the convex columns 41 in the folding area 11.

More preferably, the distribution density of the studs 41 in each odd-numbered row along the X direction is the same, and the distribution density of the studs 41 in each even-numbered row along the X direction is the same.
Referring to fig. 3 and 6, in an embodiment, in the folding region 11, the protruding pillars 41 are distributed in parallel in a plurality of rows, a direction of each row of the protruding pillars 41 forms an acute angle with the X direction, wherein a row pitch of adjacent rows is greater than a pitch between adjacent protruding pillars 41 in each row, and distribution densities of the protruding pillars 41 in each row are the same.
