Description
Technical Field
The present application relates to the field of display technologies, and in particular, to a display panel and a display device.
Background
The organic light emitting display device is a self-light emitting display device including an Organic Light Emitting Diode (OLED) including a hole injection electrode, an electron injection electrode, and an organic emission layer formed therebetween. The organic light emitting display device emits light when excitons generated due to a combination of holes injected from the hole injection electrode and electrons injected from the electron injection electrode fall from an excited state to a ground state.
The self-emission display device does not require an additional light source. The organic light emitting display device may be driven at a low voltage, and may be lightweight and formed by a thin film technology. In addition, the organic light emitting display device has high quality characteristics such as a wide viewing angle, a large contrast ratio, and a fast response speed, and thus is considered as a next generation display device.
Generally, an organic light emitting display device includes a plurality of pixels for emitting light of different colors to display an image. Here, the pixel refers to a minimum unit of a display image. Gate lines, data lines, power lines such as driving power lines, insulating layers such as pixel defining layers for defining an area or a shape of each pixel, and the like may be positioned between adjacent pixels.
In a typical organic light emitting display device, an organic emission layer for forming pixels is formed by a deposition process using a mask such as a Fine Metal Mask (FMM). A spacing column is formed between part of the pixels, and on one hand, the spacing column is used as a support between the array substrate and the packaging substrate to maintain a gap between the two substrates and keep certain impact strength; on the other hand, when the organic light emitting layer is evaporated using the fine metal mask, the spacer may also contact the fine metal mask as a support of the fine metal mask. If the pixels are formed with a small gap therebetween to ensure a good aperture ratio of the pixels, the spacer area is reduced, the strength of the fine metal mask is reduced, and the reliability of deposition may be reduced. In contrast, if the pixel is formed to have a large gap to improve the reliability of deposition, the spacer area is increased, the strength of the fine metal mask is improved, but the aperture ratio of the pixel may be reduced.
In addition, the formation of the spacers may cause process problems such as contamination, impurities, particles, etc. due to the contact of the spacers with the fine metal mask, thereby reducing the reliability of deposition, and ultimately affecting the display effect and performance of the display panel.

As one skilled in the art will appreciate, manufacturers may refer to a component by different names. This specification and claims do not intend to distinguish between components that differ in name but not function. In the following description and in the claims, the terms "include" and "comprise" are used in an open-ended fashion, and thus should be interpreted to mean "include, but not limited to. "substantially" means within an acceptable error range, and a person skilled in the art can solve the technical problem within a certain error range to substantially achieve the technical effect. The description which follows is a preferred embodiment of the present application, but is made for the purpose of illustrating the general principles of the application and not for the purpose of limiting the scope of the application. The protection scope of the present application shall be subject to the definitions of the appended claims.
Fig. 1 is a diagram of a pixel arrangement and a spacer distribution of a display panel in the prior art. R, G, B the three sub-pixels 11, 12, 13 are arranged in parallel, and as a pixel unit, the spacer 14 is located between two pixel units in the column direction, and the spacer is adjacent to R, G, B the three sub-pixels 11, 12, 13.
Since the spacer is in contact with the fine metal mask during the evaporation process, foreign matters are easily generated at the contact position to affect the light emitting quality of the sub-pixels, and the red and green pixels are more susceptible to the influence of the spacer than the blue pixels. That is, although foreign substances exist in some regions of the pixel region, the luminance reduction due to the foreign substances is more serious in the red and green pixels than in the blue pixel.
In the prior art, on one hand, the pixel arrangement mode is difficult to meet the requirement of high resolution, and on the other hand, the interval pillars are adjacent to the sub-pixels of three colors, so that the interval pillars have higher probability of abnormal light emission and poor display. If the spacers are disposed only between the blue subpixels, the area of the spacers is small, and the impact resistance of the display panel is reduced.
The application provides a display panel, including array substrate and packaging substrate, wherein the array substrate includes: a substrate base plate; the array substrate comprises a substrate base plate, a plurality of sub-pixels and a plurality of pixel units, wherein the substrate base plate is provided with a plurality of sub-pixels which are arranged in an array mode, the plurality of sub-pixels comprise a plurality of sub-pixel columns which are arranged along a row direction, each sub-pixel column comprises a plurality of pixel units which are repeatedly arranged along a column direction, each pixel unit is formed by sequentially arranging a first sub-pixel of a first color, a second sub-pixel of a second color and a third sub-pixel of a third color, and each sub-pixel column and the adjacent sub-pixel column are staggered in the column direction; and the spacing columns are positioned between two third sub-pixels which are closest to each other in the adjacent sub-pixel columns.
Specifically, fig. 2 shows a pixel arrangement and a spacer distribution of the display panel provided by the present application. The plurality of sub-pixels comprise a plurality of sub-pixel columns arranged along the row direction, each sub-pixel column comprises a plurality of pixel units 20 repeatedly arranged along the column direction, each pixel unit is formed by sequentially arranging a first sub-pixel 21 of a first color, a second sub-pixel 22 of a second color and a third sub-pixel 23 of a third color, and the third sub-pixel 23 is overlapped with one first sub-pixel 21 and one second sub-pixel 22 of an adjacent column in the column direction. Each sub-pixel column is staggered with the adjacent sub-pixel column in the column direction; and a plurality of spacer pillars 24 between the substrate base plate and the encapsulation base plate, the spacer pillars being located between two third sub-pixels closest to each other in the adjacent sub-pixel columns. The spacers 24 are in the shape of stripes, the third sub-pixels 23 are located on two sides of the extending direction of the stripe-shaped spacers, the first sub-pixels 21 and the second sub-pixels 22 are located on two sides of the spacers in the first direction, and the first direction intersects with the extending direction.
FIG. 3 is a schematic cross-sectional view of A-A' of FIG. 2. FIG. 4 is a schematic cross-sectional view of B-B' in FIG. 2. The display panel 20 includes an array substrate 201 and a package substrate 202, and a pixel definition layer 25 separates each sub-pixel. The third sub-pixels 23 (blue sub-pixels) have spacers 24 disposed therebetween, and the spacers 24 are formed on the pixel defining layer 25. The spacer 24 is arranged next to the third sub-pixel 23. In contrast to fig. 4, the distance between the spacer 24 and the first and second sub-pixels 21 and 22 is greater than the distance between the spacer 24 and the third sub-pixel 23. Because the spacing columns are only arranged among the blue sub-pixels, and the distance among the blue sub-pixels is increased under the pixel arrangement, the area of the spacing columns is correspondingly increased, and the impact strength of the display panel is improved; moreover, the distance between the spacer 24 and the first sub-pixel 21 (green sub-pixel) and the distance between the spacer 24 and the second sub-pixel 22 (red sub-pixel) are greater than the distance between the spacer 24 and the third sub-pixel 23, the influence of the spacer on the first sub-pixel 21 and the second sub-pixel 22 is reduced, the deposition stability is better than that of the prior art, and display defects and defects are not easily caused.
FIG. 5 is a diagram illustrating another pixel layout and spacer distribution of a display panel according to the present application; the spacer 24 includes a middle portion 241 and an end portion 242 adjacent to a third sub-pixel, the third sub-pixel is located on two sides of the extending direction X of the spacer, the first sub-pixel and the second sub-pixel are located on two sides of the spacer in a second direction Y, and the second direction Y intersects with the extending direction. The provision of the end portions 242 increases the area and strength of the spacer, thereby enhancing the impact strength of the display panel.
At least a part of an edge of the end portion 242 and a part of an edge of one third sub-pixel adjacent thereto are parallel to each other. Specifically, as shown in fig. 6, the third sub-pixel 23 has a square shape, and at least a part of an edge of the end portion 242 is parallel to one of the edges of the adjacent one of the third sub-pixels. In this embodiment, the spacer 24 is in the shape of a dogleg, the end portion 242 is adjacent to the third sub-pixel, and the adjacent sides are parallel to each other. The arrangement ensures that the tail end of the spacing column is matched with the edge of the third sub-pixel, so that the reduction of the aperture opening ratio or the overlarge influence on the third sub-pixel caused by the overlapping of the spacing column and the third sub-pixel can be avoided while the area is increased.
Fig. 7 is a diagram illustrating another pixel arrangement and spacer distribution of a display panel according to the present application. Similarly to fig. 6, the third sub-pixel 23 has a square shape, and at least a part of an edge of the end portion 242 and one of the edges of the adjacent one of the third sub-pixels are parallel to each other. The spacer 24 has a polygonal shape, and the end portion 242 is adjacent to the third sub-pixel, and the adjacent sides are parallel to each other. The arrangement ensures that the tail end of the spacing column is matched with the edge of the third sub-pixel, so that the reduction of the aperture opening ratio or the overlarge influence on the third sub-pixel caused by the overlapping of the spacing column and the third sub-pixel can be avoided while the area is increased.
Fig. 8 is a diagram illustrating another pixel arrangement and spacer distribution of a display panel according to the present application. Similar to fig. 6, the third sub-pixel 23 is square, and the end portion 242 has an L-shaped edge, two segments of the L-shaped edge are parallel to two adjacent edges of a third sub-pixel adjacent to the L-shaped edge, that is, a corner of the third sub-pixel 23 is just half surrounded by the L-shaped edge.
Fig. 9 is a variation of fig. 6. A plurality of spacer posts may be connected by end portions. A plurality of spacing posts are connected into a whole, so that the spacing posts become the spacing wall, and the strength is further improved.
Fig. 10 is a diagram of an octagonal sub-pixel and its corresponding spacer distribution. The third sub-pixel has an octagonal shape, has four first sides intersecting both the row direction and the column direction, and has an edge of the end portion 242 parallel to one of the first sides. The third sub-pixel is arranged to be octagonal, so that the space column 242 can be avoided to a certain extent, and the space column can be correspondingly arranged to be larger in area, and the strength of the space column is further improved.
Fig. 11 is a thickness profile of the intermediate and end portions of the spacer. The thickness of the end portion 242 in the direction perpendicular to the substrate base is larger than the thickness of the intermediate portion in the direction perpendicular to the substrate base. Since the start voltage of the blue sub-pixel is greater than the start voltages of the green sub-pixel and the red sub-pixel, when the drive voltage is applied to the blue sub-pixel, the green sub-pixel and the red sub-pixel are easily caused to be lighted by theft, and the thickness of the end portion 242 in the direction perpendicular to the substrate is greater than the thickness of the middle portion in the direction perpendicular to the substrate, which helps to prevent the green sub-pixel and the red sub-pixel from being lighted by theft when the drive voltage is applied to the blue sub-pixel.
Of course, another situation may be adopted, that is, as shown in fig. 3, the orthographic projection of the bottom of the spacer on the substrate is covered with the orthographic projection of the top of the spacer on the substrate, that is, the spacer has a wider bottom and a sharper top, and is less difficult to manufacture, and the contact area between the spacer and the fine metal mask is smaller, so that the probability of the defect caused by the foreign matter is smaller, and the reduction of the defect is facilitated.
FIG. 12 is a schematic view of a parallelogram spacer. The third sub-pixel is square in shape, the spacer 242 is parallelogram-shaped, and the edge of the spacer 242 adjacent to the third sub-pixel 23 is parallel to one side of the third sub-pixel. Such a shape is not as complex to make as the spacer shown in figures 6, 7 and 8 and at the same time satisfies the flush edge feature.
Fig. 13 shows a specific pitch setting of the pixel arrangement in the above embodiment. The distance between the first sub-pixel and the second sub-pixel in the column direction is L1, the distance between the first sub-pixel and the third sub-pixel in the column direction is L2, the distance between the second sub-pixel and the third sub-pixel in the column direction is L3, and L1< L2 and L1< L3 are satisfied.
The present invention also provides a display device 30 including the above display panel. Referring to fig. 14, the display panel provided in the above embodiments of the present application is included. The display device 30 may be: any product or component with a display function, such as a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, a navigator and the like.
