The embodiment of the application provides a display panel 100 and a display device 1000. For a better understanding of the present application, embodiments of the present application are described below with reference to fig. 1 to 8.
The display panel 100 provided in the embodiment of the present application may be an Organic Light Emitting Diode (OLED) display panel. However, this is not a limitation in the present application.
Fig. 1 illustrates a schematic top view of a display panel 100 according to an embodiment of the present application. Fig. 2 shows an exemplary cross-sectional view along a-a in fig. 1. Referring to fig. 1 and fig. 2, a display panel 100 provided in the embodiment of the present disclosure is provided with a plurality of pixels for displaying a picture. The display panel 100 has a first display region 101 and a second display region 102 disposed at least one side of the first display region 101. The display panel 100 is exemplarily illustrated in fig. 1 as a regular rectangle. In some other embodiments of the present application, the display panel 100 may also be configured to be irregular. For example, four corners of the display panel 100 may be arranged in a circular arc shape.
The display panel 100 of the embodiment of the present application includes an array substrate 10 and a light emitting device layer 70. The array substrate 10 includes a plurality of functional layers 20 stacked in a thickness direction X thereof. Adjacent functional layers 20 are insulated by an insulating layer 30. Here, the functional layer 20 has a layer structure having a predetermined function with respect to the insulating layer 30, and has conductivity or the like, for example. The light emitting device layer 70 is stacked on one side of the array substrate 10 in a thickness direction X of the array substrate 10.
In some embodiments, each functional layer 20 includes a first functional unit 21 located in the first display region 101 and a second functional unit 22 located in the second display region 102. The first functional unit 21 and the second functional unit 22 are provided independently of each other, and implement their functions, respectively. For one functional layer 20, the first functional unit 21 and the second functional unit 22 are disposed on the same layer, so that the first functional unit 21 and the second functional unit 22 can be formed in one process, which is beneficial to simplifying the manufacturing process and reducing the process production cost.
In some embodiments, among the plurality of functional layers 20, at least a portion of the second functional unit 22 of at least one functional layer 20 is disposed to be raised upward in the thickness direction X of the array substrate 10 with respect to the first functional unit 21, so that one side surface of the array substrate 10 forms a first inclined surface 10a in the second display region 102. The number of the first inclined surfaces 10a may be selected according to actual requirements. The second function unit 22 is provided to be raised means that the second function unit 22 is provided to protrude from the first function unit 21 in the thickness direction X. Illustratively, the first inclined surface 10a forms an acute angle with the horizontal plane with the state shown in fig. 2 as a reference system. The surface of the array substrate 10 has a flat surface connected to the first inclined surface 10a, and the flat surface is parallel to the horizontal plane.
In some embodiments, the light emitting device layer 70 is stacked on the surface of the array substrate 10 having the first inclined surface 10 a. The light emitting device layer 70 includes a pixel defining layer 71 and a plurality of light emitting cells 72. The pixel defining layer 71 has a plurality of openings 71 a. The light emitting unit 72 is located within the opening 71 a. The light emitting unit 72 may be an organic light emitting unit. The light emitting unit 72 may include an anode, a cathode, and an organic light emitting layer between the anode and the cathode. When a voltage is applied to the anode and the cathode, respectively, the organic light-emitting layer emits light. The light emitting unit 72 may include a red light emitting unit, a green light emitting unit, and a blue light emitting unit, thereby implementing a color display. However, the color of the light emitting unit 72 is not limited in the present application. The pixel defining layer 71 is provided with openings 71a in both the first display area 101 and the second display area 102. The opening 71a located in the second display area 102 is disposed corresponding to the first inclined surface 10 a. The light emitting unit 72 located in the second display region 102 is disposed on the first inclined surface 10 a. The light emitting direction of the light emitting unit 72 located in the second display region 102 is inclined with respect to the light emitting direction of the light emitting unit 72 located in the first display region 101, so that the light emitting direction of the light emitting unit 72 located in the second display region 102 intersects with the light emitting direction of the light emitting unit 72 located in the first display region 101.
In using electronic products having flat display screens, such as smart watches, users are accustomed to viewing the display screen from an oblique angle while viewing the image information displayed on the display screen. At this time, a predetermined angle is formed between the line of sight of the user and the perpendicular line of the display screen, so that there is a large difference between the light emitting direction of each light emitting unit 72 and the line of sight of the user, thereby causing color cast of image information observed by the user.
After the display panel 100 of the embodiment of the application is applied to an electronic product having a flat display screen, when a user observes the display screen from an inclined angle, a perpendicular line of the first inclined surface 10a of the array substrate 10 tends to be consistent with a line of sight of the user, so that a light emitting direction of the light emitting unit 72 located in the second display area 102 tends to be consistent with the line of sight of the user, thereby reducing a difference between the light emitting direction of the light emitting unit 72 and the line of sight of the user, reducing a possibility of color cast of image information observed by the user, and improving a display effect of the display panel 100.
The display panel 100 of the embodiment of the application forms the first inclined plane 10a by adopting a mode that at least a part of the second functional unit 22 of the functional layer 20 is arranged in an upward protruding manner in the thickness direction X of the array substrate 10 relative to the first functional unit 21, so that the second functional unit 22 can be formed by processing and manufacturing in a conventional manufacturing process, the second functional unit 22 does not need to be formed by additionally processing and manufacturing a special mask plate, and the processing difficulty and the processing cost are reduced.
In some embodiments, the uppermost layer of the array substrate 10 is the insulating layer 30, that is, the layer structure on the array substrate 10 near the pixel defining layer 71 is the insulating layer 30. The second functional unit 22 may be provided with bumps such that the regions of the insulating layer 30 corresponding to the second functional unit 22 are also formed with bumps, and the first inclined surfaces 10a are formed in the regions where the insulating layer 30 is bumps. Illustratively, the first inclined surface 10a is a flat surface. The first inclined surface 10a is inclined toward the side of the first display area 101, which satisfies the habit of different users viewing the display screen from different angles. The display panel 100 of the present embodiment is provided by raising at least a part of the second functional unit 22 using the functional layer 20 to jack up the insulating layer 30, so that the first inclined face 10a is formed on the insulating layer 30. Thus, the first inclined surface 10a is formed in a manner of adopting different exposure amounts at different positions of the insulating layer 30 without additionally using a special mask plate, so that the processing difficulty and the processing cost can be effectively reduced.
In some embodiments, the second functional unit 22 of the functional layer 20 adjacent to the pixel defining layer 71 has the second inclined surface 23. The first inclined surface 10a is parallel to the second inclined surface 23. When the first inclined surface 10a is formed on the insulating layer 30, the region of the insulating layer 30 corresponding to the second inclined surface 23 may be formed to have an equal thickness structure. The area of the second inclined surface 23 is equal to or larger than the area of the first inclined surface 10 a.

The second functional units 22 of the three functional layers 20 are each disposed to rise upward, and the second functional unit 22 of the functional layer 20 located above has a second inclined surface 23 itself. In the thickness direction X, the second functional unit 22 of the middle functional layer 20 and the second functional unit 22 of the lower functional layer 20 raise the second functional unit 22 of the upper functional layer 20 in a superimposed manner, so that the thickness of the second functional unit 22 of the upper functional layer 20 can be reduced while the second functional unit 22 of the upper functional layer 20 is raised by a predetermined height.
Two insulating layers 30 are provided between the functional layer 20 and the pixel defining layer 71 located above. The second functional units 22 of the respective three functional layers 20 are each provided with a ridge so that the two insulating layers 30 between the upper functional layer 20 and the pixel defining layer 71, the insulating layer 30 between the upper functional layer 20 and the intermediate functional layer 20, and the insulating layer 30 between the intermediate functional layer 20 and the lower functional layer 20 each form a ridge in the corresponding region, and the first inclined surface 10a is formed on the upper insulating layer 30.

Thus, when a user uses an electronic product with a bent display screen, the line of sight of the user is kept parallel to the perpendicular line of the first display area 101, and is also kept parallel to the perpendicular line of the second display area 102, so that the difference between the light emitting directions of the light emitting units 72 in the first display area 101 and the second display area 102 and the line of sight of the user is reduced, the possibility of color cast of image information observed by the user is reduced, and the display effect of the display panel 100 is improved.
In some embodiments, the second display region 102 is bent to have a straight structure. The inclination angle of the first inclined surface 10a is equal to the bending angle of the second display area 102 relative to the first display area 101, so that the light emitting surface of each light emitting unit 72 on the second display area 102 is parallel to the light emitting surface of the light emitting unit 72 located in the first display area 101. The inclination angle of the first inclined surface 10a may be selected according to actual product requirements.
In some embodiments, the second display area 102 is curved. In a direction away from the first display area 101, the bending degree of the second display area 102 relative to the first display area 101 gradually increases. The inclination degree of the first inclined surface 10a gradually increases along a direction away from the first display area 101, so that the light-emitting surfaces of the light-emitting units 72 at different positions on the second display area 102 and the light-emitting surfaces of the light-emitting units 72 in the first display area 101 are parallel.
In some embodiments, a bump 31 is provided on the insulating layer 30 under the second functional unit 22 to bump the second functional unit 22 by the bump 31. Referring to fig. 7, a bump 31 is provided on one of the insulating layers 30 adjacent to the substrate 40. The bump 31 on the insulating layer 30 may cause the second functional units 22 of the upper two functional layers 20 to be disposed with upward bumps. The second functional unit 22 of the upper functional layer 20 forms the second inclined surface 23, and the first inclined surface 10a is formed on the upper insulating layer 30. The present embodiment adopts a manner in which the second function unit 22 is raised by providing the raised portion 31 on the insulating layer 30 to jack up the second function unit 22. Illustratively, the second functional units 22 of both functional layers 20 may be provided in an equal thickness structure. It is to be understood that the present embodiment is not limited to providing the bump 31 on one of the insulating layers 30 adjacent to the substrate 40. The insulating layer 30 between the two second functional units may be provided with a swelling portion 31 to swell the second functional unit 22 of the upper functional layer 20 and form the second inclined surface 23, and the first inclined surface 10a is formed on the upper insulating layer 30.
