Detailed Description
In order to weaken the sawtooth phenomenon of the special-shaped edge of the special-shaped display panel and improve the effect of the display panel near the special-shaped edge, the embodiment of the invention provides an organic light-emitting display panel and a display device. In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail by referring to the following examples.
As shown in fig. 2, 3 and 4, an organic light emitting display panel provided by an embodiment of the present invention includes an array substrate 1 and a plurality of pixel units 2, the array substrate 1 includes a display area 11 and a non-display area 12 surrounding the display area 11, the display area 11 has a shaped edge 113; the pixel unit 2 is formed in the display area 11 of the array substrate 1, the pixel unit 2 includes a plurality of sub-pixels 21, the sub-pixels 21 include a first electrode layer 213, a light emitting pixel layer 214 and a second electrode layer 215 which are sequentially arranged, wherein the display area 11 includes an irregular display area 111 close to the irregular edge 113 and a central display area 112 far away from the irregular edge 113, and the number of the sub-pixels 21 in at least one row and/or at least one column of the irregular display area 111 is different; the area of the first electrode layer 213 of the sub-pixel 21 of the shaped display region 111 is smaller than the area of the first electrode layer 213 of the sub-pixel 21 of the central display region 112, and/or the area of the second electrode layer 215 of the sub-pixel 21 of the shaped display region 111 is smaller than the area of the second electrode layer 215 of the sub-pixel 21 of the central display region 112.
In the embodiment of the present invention, the area of the first electrode layer 213 of the sub-pixel 21 of the irregular-shaped display region 111 is smaller than the area of the first electrode layer 213 of the sub-pixel 21 of the central display region 112. Then compared to the central display area 112. The light emitting area of the sub-pixel 21 of the shaped display region 111 is small, and thus the light emitting luminance is low, the jaggy feeling at the shaped edge 113 can be weakened.
Referring to fig. 4, fig. 4 is a schematic cross-sectional view of a display area of an organic light emitting display panel in an embodiment, specifically, the organic light emitting display panel includes a substrate 4, an array layer 5, an organic light emitting device 6 and a thin film encapsulation layer 7, wherein: the array layer 5 on the substrate 4 may be a top gate structure, and the array layer 5 sequentially includes a first insulating layer 51, an active layer 52, a second insulating layer 53, a first metal layer 54, a third insulating layer 55, and a second metal layer 56 along a direction away from the substrate 4, and the second metal layer 56 is connected to the active layer 52 through a via hole. It should be noted that, in other embodiments, the array layer 5 may also be a bottom gate structure, which is not limited in this embodiment of the present invention.
The organic light-emitting device 6 includes a planarization layer 61, a first electrode layer 213, a light-emitting pixel layer 214, and a second electrode layer 215, and a pixel defining layer 62 in this order in a direction away from the substrate 4. The pixel defining layer 62 is disposed between the first electrode layer 213 and the second electrode layer 215 to partition the light emitting pixel layer 214 into light emitting pixels. In the organic light emitting device 6, holes (electrons) are generated from the first electrode and electrons (holes) are generated from the second electrode, and injected into the light emitting pixel layer 214. The injected electrons and holes combine with each other to form excitons, and the organic light-emitting device 6 emits light by energy generated when the excitons drop from an excited state to a ground state. The organic light emitting device 6 may further include one or more of a hole injection layer, a hole transport layer, an electron blocking layer, a hole blocking layer, an electron transport layer, and an electron injection layer. The light emitting layer 33 may be a red light emitting layer, a green light emitting layer, or a blue light emitting layer. The light emitting layer 33 may be a single white light emitting layer. The light emitting layer 33 may have a laminated structure of a red light emitting layer, a green light emitting layer, and/or a blue light emitting layer. When the light emitting layer 33 has a stacked structure, a color filter (not shown) may be included. A hole injection layer and/or a hole transport layer may be disposed between the anode layer and the light emitting layer. The electron injection layer and/or the electron transport layer may be disposed between the cathode layer and the light emitting layer, and in the embodiment of the present invention, one of the first electrode and the second electrode may be an anode, and the other electrode is a cathode, which is not limited to the present invention, and those skilled in the art may set the electron injection layer and/or the electron transport layer as needed.
It should be noted that the area of the first electrode layer 213 of the sub-pixel 21 of the irregular-shaped display region 111 is smaller than the area of the first electrode layer 213 of the sub-pixel 21 of the central display region 112, which means that the area of the sub-pixel 21 of each color of the display panel may be different in practical applications compared to the sub-pixel 21 of the same color, and therefore, the sub-pixels 21 of different colors may not be compared.
In the present invention, the display area 11 has an irregular edge 113, which results in different numbers of sub-pixels 21 in at least one row and/or at least one column of the irregular display area 111; alternatively, it can be considered that the number of sub-pixels 21 in at least one row and/or at least one column of the shaped display area 111 is different, so that the shaped edge 113 is formed in the display area 11.
Referring to fig. 3, in an embodiment, the areas of the first electrode layer 213, the light emitting pixel layer 214 and the second electrode layer 215 of the sub-pixel 21 of the irregular display region 111 are substantially the same, that is, the area of the sub-pixel 21 of the irregular display region 111 is smaller than the area of the sub-pixel 21 of the central display region 112. In this embodiment, the area of the sub-pixels 21 in the irregular display region 111 can be directly reduced, and the first electrode layer 213 is not separately processed. In the embodiment, each layer of the sub-pixels can share one set of mask during manufacturing, and the mask does not need to be designed according to the structures of different layers, so that the cost is saved.
Referring to fig. 7, in another embodiment, the sub-pixel 21 of the irregular-shaped display area 111 includes a light-emitting area 211 and a non-light-emitting area 212, the light-emitting pixel layer 214 and the second electrode layer 215 both cover the light-emitting area 211 and the non-light-emitting area 212 of the sub-pixel 21, and the first electrode layer 213 covers the light-emitting area 211.
In this embodiment, it can be considered that the area of the sub-pixel 21 of the irregular display region 111 is the same as the area of the sub-pixel 21 of the central display region 112, and only the first electrode layer 213 is provided with a notch structure, so as to form the light-emitting region 211 covered by the first electrode layer 213 and the non-light-emitting structure exposed by the notch structure. In this embodiment, the area of the sub-pixel 21 in the irregular display region 111 is the same as the area of the sub-pixel 21 in the central display region 112, and the structures of the sub-pixels 21 other than the first electrode layer 213 may be manufactured in a unified manner when manufacturing the substrate, but a notch structure may be formed when manufacturing the first electrode layer 213 of the sub-pixel 21 in the irregular display region 111. For example, when the first electrode layer 213 of the sub-pixel 21 in the irregular display region 111 is evaporated, a mask having a suitable shape is used to form the above-mentioned notch structure.
When the sub-pixels 21 are manufactured, a mask is needed in the evaporation process, and if openings of the mask are not uniform, the mask may be wrinkled, so that the openings of the mask are deformed, and the evaporation effect is affected. In addition, each step of manufacturing the sub-pixel 21 needs to perform process detection, in this embodiment, except for the first electrode layer 213, the sub-pixels 21 of the display panel have the same structure, and only the mask for evaporating the first electrode layer 213 needs to be designed with uneven openings, so that the probability of product defects can be reduced.
Specifically, the first electrode layer 213 may be an anode layer or a cathode layer, that is, as shown in fig. 5, the first electrode layer 213 may be an anode layer, and the second electrode layer 215 may be a cathode layer; alternatively, as shown in fig. 6, the first electrode layer 213 is a cathode layer and the second electrode layer 215 is an anode layer.
In general, the anode layer is separately provided for each sub-pixel, and in the display panel, the anode layer of each sub-pixel works separately, and there is no mutual influence between the anode layers of different sub-pixels, that is, the area of the anode layer of a sub-pixel is changed, and only the light emitting brightness of the sub-pixel itself is affected. Therefore, the area of the anode layer of the sub-pixel of the special-shaped display area is reduced in the scheme, the brightness of the special-shaped display area is reduced, the special-shaped edge sawtooth phenomenon of the special-shaped display panel is weakened, and in addition, the display effect of the central display area is not reduced in the scheme.
In the alternative embodiment with continued reference to fig. 7, the ratio of the area of the non-light-emitting region 212 to the sub-pixel 21 gradually increases along the direction approaching the irregular edge 113. That is, the area of the non-light region of the sub-pixel 21 of the same color is larger and the area of the light-emitting region 211 is smaller closer to the special-shaped edge 113, and the light-emitting luminance of the display region 11 is lower closer to the special-shaped edge 113, which is more advantageous for improving the effect of weakening the jaggy feeling, and furthermore, the display panel becomes gradually darker in a direction closer to the special-shaped edge 113 to reduce the abrupt change in the display luminance of the display panel.
In general, the same pixel unit 2 at least includes three color sub-pixels 21 of the red sub-pixel 21, the green sub-pixel 21 and the blue sub-pixel 21, and the area of the sub-pixels 21 of the respective colors may be different from various viewpoints, so in the present application, the area ratio of the non-light-emitting area 212 of each sub-pixel 21 to the sub-pixel 21 is emphasized, rather than simply limiting the area of the non-light-emitting area 212. Of course, in a specific embodiment, there may be other choices for the sub-pixels 21 included in the same pixel unit 2, such as sub-pixels 21 of four colors including a red sub-pixel 21, a green sub-pixel 21, a blue sub-pixel 21, and a white sub-pixel 21, which are not listed here.
In a further embodiment, the area ratio in the plurality of pixel cells 2 increases linearly in a direction close to the shaped edge 113.
In this embodiment, the ratio of the area of the non-light emitting region 212 in the sub-pixel 21 increases linearly in a direction near the shaped edge 113. The luminance of the special-shaped display area 111 can be gradually changed, which is beneficial to improving the effect of weakening the saw-tooth feeling, and the change step difference of the luminance from the central display area 112 to the special-shaped display area 111 and further to the special-shaped edge 113 can be reduced, so that the sudden change of the display luminance of the display panel is reduced.
In an alternative embodiment, in each sub-pixel 21 of the same pixel unit 2, the area ratio of the non-light-emitting region 212 to the sub-pixel 21 is the same.
The embodiment can make the display panel not easy to generate color shift defect when displaying, and the ratio of the light emitting region 211 of each sub-pixel 21 in the same pixel unit 2 should be unchanged, thereby improving the display effect.
With continued reference to FIG. 7, in an alternative embodiment, the non-light emitting region 212 is located on a side of the sub-pixel 21 near the shaped edge 113. In this embodiment, the non-light emitting region 212 is closer to the shaped edge 113 side, and the reduction degree of the luminance can be further made larger in the region closer to the shaped edge 113.
With continued reference to fig. 7, in a further embodiment, the non-light-emitting region 212 is located at the edge of the sub-pixel 21. Also, in this embodiment, the non-light emitting region 212 is located at the edge of the sub-pixel 21, particularly on the side near the shaped edge 113, and the degree of reduction in luminance in the area of the shaped edge 113 can be made larger.
Of course, the present invention does not limit the position of the non-light-emitting region 212 in the sub-pixel 21, as shown in fig. 8, the non-light-emitting region 212 may also be located inside the sub-pixel 21, and specifically, the position where the non-light-emitting region 212 is disposed may be set according to actual requirements.
In alternative embodiments, the non-light-emitting region 212 includes a circular non-light-emitting region, a fan-shaped non-light-emitting region, a rectangular non-light-emitting region, a triangular non-light-emitting region, an L-shaped non-light-emitting region, or a zigzag non-light-emitting region.
In the present application, the cross-sectional shape of the non-light-emitting region 212 is not particularly limited, so that an edge of a different shape, such as an arc edge, a diagonal edge, or a broken line edge, is formed on the side of the light-emitting region 211 close to the non-light-emitting region 212. For example, as shown in fig. 9, the non-light-emitting region 212 is a fan-shaped non-light-emitting region, and the edge of the light-emitting region 211 near the non-light-emitting region 212 is an arc-shaped edge; alternatively, as shown in fig. 10, the non-light-emitting region 212 is a circular non-light-emitting region, and similarly, the edge of the light-emitting region 211 close to the non-light-emitting region 212 is an arc-shaped edge; as shown in fig. 11, the non-light-emitting region 212 is a triangular non-light-emitting region, and the edge of the light-emitting region 211 close to the non-light-emitting region 212 is a diagonal edge; as shown in fig. 8, the non-light-emitting region 212 is a rectangular non-light-emitting region 2, and the edge of the light-emitting region 211 close to the non-light-emitting region 212 is a broken line edge; as shown in fig. 12, the non-light-emitting region 212 is an L-shaped non-light-emitting region, and as shown in fig. 13, the non-light-emitting region 212 is a zigzag non-light-emitting region, and the edges of the corresponding light-emitting regions 211 close to the non-light-emitting region 212 are all broken line edges. As described above as several embodiments, the shape of the non-light-emitting region may be specifically determined according to actual conditions.
Referring to fig. 14, in an embodiment, the non-light-emitting region 212 may be located at an edge of the sub-pixel 21 close to the special-shaped edge 113, and further, the edge of the light-emitting region 211 close to the non-light-emitting region 212 is a slant line edge or a curved line edge, and an extending trend of the slant line edge or the curved line edge is consistent with an extending trend of the special-shaped edge 113, so as to be more beneficial to reducing the jaggy feeling of the display region 11 at the special-shaped edge 113. For example, taking the embodiment shown in fig. 14 as an example, the special-shaped edge 113 of the display area 11 is a diagonal special-shaped edge, the non-light-emitting area 212 is located at the edge of the sub-pixel 21 close to the special-shaped edge 113, the edge of the light-emitting area 211 is also a diagonal edge, and the inclination angle of the diagonal edge is substantially the same as the inclination angle of the diagonal special-shaped edge, and this configuration can make the edge formed by the plurality of sub-pixels 21 close to the special-shaped edge 113 tend to be the diagonal special-shaped edge, and can further weaken the jaggy feeling of the display area 11.
Referring to fig. 15 to 17, in an embodiment, the shape of the special-shaped edge 113 is not limited, and the special-shaped edge 113 may be a curved special-shaped edge or a diagonal special-shaped edge. In the organic light emitting display panel shown in fig. 15 and 16, the shaped edge 113 is a curved shaped edge, and in the organic light emitting display panel shown in fig. 17, the shaped edge 113 is a diagonal shaped edge. Specifically, the specific shape of the curved shaped edge 113 is not limited, for example, as shown in fig. 15, the curved shaped edge 113 may be a circular arc shaped edge, and as shown in fig. 15, the curved shaped edge is a rounded shaped edge; alternatively, the curved shaped edge 113 may also be an irregularly curved shaped edge, such as the organic light emitting display panel shown in fig. 16, the curved shaped edge being an irregularly curved shaped edge.
Referring to fig. 18, the specific position of the special-shaped edge is not specifically limited, and may be located at four corners of the display area, or may be located at other positions of the display area, for example, if there is a cut 3 on the display area, then there is a special-shaped edge 113 at the cut 3.
Referring to fig. 19, an embodiment of the invention further provides a display device 100, where the display device 100 includes the organic light emitting display panel 200 in any of the above technical solutions.
The organic light emitting display panel of the display device includes an irregular edge 113, and an irregular display region 111 is provided near the irregular edge 113, and an area of the first electrode layer 213 of the sub-pixel 21 of the irregular display region 111 is smaller than an area of the first electrode layer 213 of the sub-pixel 21 of the central display region 112.
