The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present invention based on the embodiments herein.
Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of a first embodiment of a display panel according to the present application, and fig. 2 is a detailed partial schematic diagram of the display panel in fig. 1. In the present embodiment, the display panel 10 includes a counter substrate (not shown), a liquid crystal layer and an array substrate (not shown), and the liquid crystal layer is disposed between the counter substrate and the array substrate. And the array substrate further comprises a plurality of data lines 11, a plurality of scanning lines 12 and a plurality of pixels 13.
It can be understood that, to achieve normal display of the display panel 10, a plurality of data lines 11 and a plurality of scan lines 12 are generally configured correspondingly in the display panel 10, so as to convey the content intended to be displayed by the display panel 10 through the data lines 11, and provide the on-off voltage of the corresponding switch of each pixel 13 through the scan lines 12.
Specifically, the plurality of scan lines 12 and the plurality of data lines 11 are generally arranged in rows and columns, and specifically, the plurality of scan lines 12 are arranged in parallel with each other at intervals, and the plurality of data lines 11 are also arranged in parallel with each other at intervals and mutually intersect the plurality of scan lines 12 to define a plurality of pixel areas, and the plurality of pixels 13 are respectively and correspondingly arranged in the plurality of pixel areas, and specifically, each pixel area therein is provided with one pixel 13.
The pixels 13 can be understood as basic units for realizing the display function, so that after the pixels 13 are arranged in an array, the display panel 10 can correspondingly realize the content display, and it can be known that the direction of the light emitted by each pixel 13, that is, the opposite direction of one side of each pixel 13 facing the package surface outside the display panel 10, is the display direction of the display panel 10.
It should be noted that, fig. 2 is a schematic diagram of one pixel area in the display panel 10, that is, one data line 11, one scan line 12, and one pixel 13, and the plurality of pixel areas in the display panel 10 are specifically obtained by performing corresponding array arrangement on the pixel areas shown in fig. 2, and the bias directions of each pixel 13 are the same.
For convenience of understanding, taking the extending direction of the scan lines 12 as an example of the first direction, it can be known that the plurality of scan lines 12 are disposed in parallel with each other in the first direction, and when the first center line 1301 of each pixel 13 forms the first included angle a with the first direction, a side surface of the corresponding plurality of pixels 13 facing the outer package surface of the display panel 10 forms a set included angle with the outer package surface, that is, the display direction of the display panel 10 forms a set included angle with the outer package surface, and the set included angle and the first included angle a satisfy a certain corresponding relationship. Referring to fig. 2, a first center line 1301 of the pixel 13 is a center line extending along a length direction thereof, and a second center line 1302 of the pixel 13 is a center line extending along a width direction thereof. Wherein the second centerline 1302 is perpendicular to the first centerline 1301. In other embodiments, the first centerline 1301 and the second centerline 1302 may also be interchanged.
In this embodiment, the first included angle a is specifically greater than 0 and less than 90 °.
It can be understood that, in a normal case, the outer packaging surface of the display panel 10 and the display direction thereof are perpendicular to each other, the direction in which the user looks at the outer packaging surface of the display panel 10 perpendicularly is the front view state, and after changing the display direction of the display panel 10 by changing the offset direction of each pixel 13, the viewing angle corresponding to the display direction is the front view state, and in the front view state, the best viewing effect can be obtained.
In a specific application scenario, taking the display panel 10 as an automobile screen as an example, since the central control screen of the cab, that is, the automobile screen is usually located in the middle of the automobile body, and the view angle of the driver looking at the central control screen is not a front view angle for the existing automobile display screen, the driver may need to lean on to see the screen information better, so that the driving safety is greatly affected.
When the first included angle a formed by the first center line 1301 of each pixel 13 and the first direction is adjusted, the display direction of the display panel 10 is deflected to correspond to the viewing angle of the driver, the problem can be overcome, and the viewing direction of the driver corresponds to the front viewing angle, so that a better viewing effect can be obtained.
It is to be understood that, in any other reasonable application scenario, when the viewing angle of the display panel 10 in the normal case is other, the first included angle a may also be any other reasonable angle, for example, any one of 90 ° -180 °, so as to enable the display direction of the display panel 10 to correspond to the normal viewing angle, which is not limited in this application.
In the above-mentioned scheme, the first center line 1301 of each pixel 13 in the display panel 10 forms the first included angle a with the extending direction, that is, the first direction, of the plurality of scan lines 12, and the first included angle is greater than 0 and smaller than 90 °, that is, the first included angle a may be specifically set according to the normal viewing angle of the viewer of the display panel 10, so as to better conform to the viewing angle of the viewer, so that the viewer can better see the display information of the display panel 10, and obtain a better viewing experience.
In this embodiment, the plurality of data lines 11 are parallel to each other in a second direction, and the second direction forms a second included angle b with the first direction, where the second included angle b may be 90 ° specifically, that is, the second direction is perpendicular to the first direction. Therefore, the arrangement of the data lines 11 and the scan lines 12 does not need to be changed, and the complexity of wiring is not increased.
Referring further to fig. 3, fig. 3 is a cross-sectional view of a portion of the structure of the pixel in fig. 1. In this embodiment, each pixel 13 in the display panel 10 further includes a first transparent electrode layer 130, an insulating layer 139, and a second transparent electrode layer 131 that are sequentially stacked, and a plurality of slits 1311 are further disposed on the surface of the second transparent electrode layer 131, so as to correspondingly realize normal display of the pixel 13. The first transparent electrode layer 130 is a whole layer, the insulating layer 139 is laid on the first transparent electrode layer 130, and the second transparent electrode layer 131 is disposed on a side of the insulating layer 139 away from the first transparent electrode layer 130. The insulating layer 139 separates the first transparent electrode layer 130 and the second transparent electrode layer 131, preventing the first transparent electrode layer 130 from conducting with the second transparent electrode layer 131. At least part of the second transparent electrode 131 is disposed in a stripe shape, thereby forming a slit 1311. The insulating layer 139 may be exposed at the slit 1311.
In the present embodiment, the plurality of slits 1311 includes a plurality of first slits 13111 disposed in parallel with each other and a plurality of second slits 13112 disposed in parallel with each other, and the plurality of first slits 13111 and the plurality of second slits 13112 are disposed symmetrically with respect to the second center line 1302 of the pixel 13. In other embodiments, the extending directions of each first slit 13111 and each second slit 13112 may also be different, which is not limited in this application.
In an embodiment, the pixel 13 further includes a liquid crystal layer 132, and the alignment direction of the liquid crystal layer 132, that is, the initial bias direction of the liquid crystal molecules in the liquid crystal layer 132 forms a third angle c with the first direction, and the third angle c is greater than 0 and less than 90 °. This is provided to secure the display effect of the display panel 10. For clarity of description, only one liquid crystal molecule in the liquid crystal layer 132 is shown in the drawings as an example, and is not limited thereto.
In an embodiment, the extending direction of each slit 1311 on the transparent electrode layer 131 forms a fourth included angle d with the alignment direction of the liquid crystal layer 132, where the fourth included angle d is 15 ° -45 °, and is specifically determined by the viewing angle of the user, for example, so as to enable the display direction of the finally obtained display panel 10 to correspond to the normal viewing angle of the viewer of the automobile screen, so that the display panel can be widely applied to the automobile screen.
In another embodiment, the first center line 1301 of the pixel 13 forms a first angle a with the first direction from one side to the other side of the display panel 10, and the first angle a is gradually changed from small to large or from large to small. This arrangement is to take into account that different display directions of the display panel 10 are required, since the distances from different positions of the display panel 10 to the eyes of a person are different, resulting in different angles, when the person is looking. The arrangement can better improve the visual experience of the user, for example, when a driver looks at the display panel 10 positioned in the middle of the center console, no matter which position of the display panel 10 is seen, the driver looks at the display panel with a front view angle, so that the effect of front view can be achieved when the user looks at the display panel from side.
Alternatively, the display panel 10 is of a fringe field switching type. In other embodiments, the display panel 10 may be any other reasonable display screen, for example, IPS (In Plane Switching, in-plane switching) type, which is not limited in this application.
It should be noted that, the FFS technology is called "fringe field switching technology" (Fringe Field Switching abbreviated as FFS), which is a wide viewing angle technology developed by liquid crystal boundaries for solving the problems of large-size, high-definition desktop displays and lcd-tv applications, and is also called "hard screen technology" in common use. The FFS technique is to rotate the inside of the electrode surface layer of the liquid crystal molecules which are almost homogeneously aligned in the plane by a boundary electric field, thereby generating a high penetration effect.
It is understood that the display panel 10 specifically further includes any reasonable component such as a common electrode, a thin film transistor layer, etc., and the component that is not illustrated is specifically the same as the conventional arrangement, and will not be described in detail herein.
Referring to fig. 4 and 5, fig. 4 is a schematic structural view of a second embodiment of the display panel of the present application, and fig. 5 is a detailed partial schematic view of the display panel of fig. 4. In this embodiment, on the basis of the first embodiment of the display panel provided in the present application, the plurality of data lines 21 in the display panel 20 are specifically spaced parallel to each other in a third direction, and the third direction forms a second included angle b with the extending direction of the scan line 22, that is, the first direction, and the second included angle b is greater than 0 and less than 90 °.
It can be understood that, by adjusting the second included angle b formed by the third direction and the first direction, the distance between each pixel 23 and the adjacent data line 21 can be effectively reduced, and the arrangement of the corresponding plurality of pixels 23 can be more compact, so that the aperture ratio of the display panel 20 can be effectively increased.
The aperture ratio is a ratio between an area of a light passing portion excluding a wiring portion and a transistor portion (normally hidden by a black matrix) of each pixel 23 and an area of the entire pixel 23. The higher the aperture ratio, the higher the efficiency of light passage.
In this embodiment, the first center line 2301 of each pixel 23 in the display panel 20 is parallel to the third direction, so that each pixel 23 is closer to the adjacent data line 21, and can be closer to each adjacent two pixels 23, and the corresponding plurality of pixels 23 can be arranged more tightly, so that the density of the pixels 23 is increased, and the aperture ratio of the display panel 20 can be effectively increased.
It can be understood that in the present embodiment, the scan line 22, the pixel 23, the first transparent electrode layer 230, the second transparent electrode layer 231, the liquid crystal layer 232, the first center line 2301, the second center line 2302, the slit 2311, the first slit 23111, and the second slit 23112 are the same as the scan line 12, the pixel 13, the first transparent electrode layer 130, the second transparent electrode layer 131, the liquid crystal layer 132, the first center line 1301, the second center line 1302, the slit 1311, the first slit 13111, and the second slit 13112, respectively, and detailed descriptions thereof will be omitted herein.

In fact, the foregoing embodiments may be simplified as needed, and it is only necessary to ensure that the array substrate includes a plurality of data lines, a plurality of scan lines, and a plurality of pixels, where the plurality of scan lines and the plurality of data lines intersect each other to define a plurality of pixel regions, and the plurality of pixels are respectively disposed in the plurality of pixel regions correspondingly, where the plurality of scan lines are spaced parallel to each other in a first direction, and a first center line of each pixel forms a first included angle with the first direction, and the first included angle is greater than 0 and less than 90 °.
