Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the 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.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of a display panel according to a first embodiment of 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), wherein the liquid crystal layer is disposed between the counter substrate and the array substrate. The array substrate further includes a plurality of data lines 11, a plurality of scan lines 12, and a plurality of pixels 13.
It is understood that, in order to realize normal display of the display panel 10, a plurality of data lines 11 and a plurality of scan lines 12 are generally correspondingly disposed in the display panel 10, so as to transmit the content, which is 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 and spaced apart from each other, and the plurality of data lines 11 are also arranged in parallel and spaced apart from each other and intersect with the plurality of scan lines 12 to define a plurality of pixel regions, and the plurality of pixels 13 are respectively and correspondingly arranged in the plurality of pixel regions, and specifically, one pixel 13 is arranged in each of the plurality of pixel regions.
The pixels 13 can be understood as basic units for realizing a display function, so that the display panel 10 can correspondingly realize content display after the plurality of pixels 13 are correspondingly arrayed, and it can be known that a direction of light emitted by each pixel 13, that is, a facing direction of a side surface of each pixel 13 facing to an outer package surface of the display panel 10 is a display direction of the display panel 10.
It should be noted that fig. 2 is a schematic diagram of a pixel region in the display panel 10, that is, the pixel region includes a data line 11, a scan line 12 and a pixel 13, and a plurality of pixel regions in the display panel 10 are obtained by performing corresponding array arrangement on the pixel regions shown in fig. 2, and the offset directions of each pixel 13 are the same.
For convenience of understanding, taking the extending direction of the scan lines 12 as the first direction as an example, it can be known that the scan lines 12 are specifically arranged in parallel and at intervals in the first direction, and when the first central line 1301 of each pixel 13 forms a first included angle a with the first direction, a side surface of the corresponding pixel 13 facing the outer package surface of the display panel 10 and the outer package surface form a set included angle, that is, the display direction of the display panel 10 and the outer package surface form a set included angle, and the set included angle and the first included angle a satisfy a certain corresponding relationship. As shown in fig. 2, the first center line 1301 of the pixel 13 is a center line extending along the length direction thereof, and the second center line 1302 of the pixel 13 is a center line extending along the 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 be interchanged.
In the present embodiment, the first included angle a is greater than 0 and less than 90 °.
It can be understood that, in a normal situation, the outer package surface of the display panel 10 and the display direction thereof are perpendicular to each other, the direction in which the user vertically looks at the outer package surface of the display panel 10 is the front-view state, and after the display direction of the display panel 10 is changed by changing the offset direction of each pixel 13 therein, 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, for illustration, since the central control screen of the cab, that is, the automobile screen, is usually located at the middle position of the vehicle body, and the viewing angle from the driver to the central control screen is not the front viewing angle for the existing automobile display screen, the driver may need to lean to see the screen information better, thereby greatly affecting the driving safety.
By adjusting the first included angle a formed by the first center line 1301 of each pixel 13 and the first direction, the display direction of the finally obtained display panel 10 can be deflected, and when the display direction corresponds 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 understood that, in any other reasonable application scenario, when the viewing angle of the display panel 10 in the normal situation is other situations, the first included angle a may also be any other reasonable angle, for example, any one of 90 ° to 180 °, so as to correspond to the display direction of the display panel 10 corresponding to the viewing angle in the normal situation, which is not limited in this application.
In the above scheme, a first included angle a is formed between the first center line 1301 of each pixel 13 in the display panel 10 and the extending direction of the plurality of scanning lines 12, that is, the first direction, 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 front viewing angle of the viewer under the normal condition of the display panel 10, so that the first included angle a better conforms to the viewing angle of the viewer, and thus the viewer can better see the display information of the display panel 10, and obtain better viewing experience.
In the embodiment, the data lines 11 are specifically spaced in parallel in a second direction, and the second direction and the first direction form a second included angle b, where the second included angle b may be specifically 90 °, that is, the second direction is perpendicular to the first direction. Therefore, the arrangement of the data lines 11 and the scanning 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 pixel of 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, which are sequentially stacked, and the surface of the second transparent electrode layer 131 is further provided with a plurality of slits 1311, so as to correspondingly realize normal display of the pixel 13. The first transparent electrode layer 130 is disposed as a whole layer, the insulating layer 139 is disposed 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, and prevents the first transparent electrode layer 130 and the second transparent electrode layer 131 from being electrically connected. At least a portion of the second transparent electrode 131 is arranged 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 include a plurality of first slits 13111 arranged in parallel with each other at an interval and a plurality of second slits 13112 arranged in parallel with each other at an interval, and the plurality of first slits 13111 and the plurality of second slits 13112 are arranged symmetrically with respect to the second center line 1302 of the pixel 13. In other embodiments, the extending direction 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 included angle c with the first direction, and the third included angle c is greater than 0 and smaller than 90 °. This is provided to ensure the display effect of the display panel 10. For clarity of presentation, only one liquid crystal molecule in the liquid crystal layer 132 is shown in the drawings as an example and not limited thereto.
In an embodiment, the extending direction of each slit 1311 on the transparent electrode layer 131 forms a fourth angle d with the alignment direction of the liquid crystal layer 132, and the fourth angle d is 15 ° to 45 °, and is determined by the viewing angle of the user, for example, so as to correspond to the display direction of the finally obtained display panel 10 to the viewing angle of the car screen, which is the normal viewing angle of the driver, and thus can be widely applied to the car screen, which is not limited in this application.
In another embodiment, a first included angle a formed by the first center line 1301 of the pixel 13 and the first direction is gradually increased from small to large or from large to small from one side to the other side of the display panel 10. This arrangement is to take into account that different display directions of the display panel 10 are required because different positions of the display panel 10 have different distances to human eyes and thus different angles when a person observes. The arrangement can better improve the visual experience of the user, for example, when the driver looks at the display panel 10 located in the middle of the center console, no matter which position of the display panel 10 is seen, the driver looks at the front view angle, so that the front view effect can be achieved when the user looks at the display panel.
Alternatively, the display panel 10 is a fringe field switching type. In other embodiments, the display panel 10 may be any other reasonable type of display screen, such as an IPS (In Plane Switching) type, which is not limited In this application.
It should be noted that FFS technology is called "Fringe Field Switching technology" (FFS for short) in its entirety, which is a wide viewing angle technology developed in the liquid crystal industry for large-size and high-definition desktop displays and liquid crystal televisions, that is, a commonly known "hard screen technology" in the present. The FFS technique is a technique in which a boundary electric field is used to rotate the inside of the electrode surface layer of liquid crystal molecules that are almost uniformly aligned in a plane, thereby generating a high-transmittance effect.
It can be understood that the display panel 10 further includes any reasonable component such as a common electrode and a thin film transistor layer, and the component that is not described is the same as the conventional component, and is not described in detail here.
Referring to fig. 4 and 5, fig. 4 is a schematic structural diagram of a second embodiment of a display panel of the present application, and fig. 5 is a detailed partial schematic diagram of the display panel in fig. 4. In the present embodiment, on the basis of the first embodiment of the display panel provided in the present application, the data lines 21 in the display panel 20 are specifically spaced in parallel in a third direction, and the third direction and the extending direction of the scan lines 22, that is, the first direction, form a second included angle b, and the second included angle b is greater than 0 and smaller than 90 °.
It can be understood that, by adjusting the second included angle b formed between the third direction and the first direction, the distance between each pixel 23 and the data line 21 adjacent to the pixel can be effectively smaller, and the arrangement of the corresponding pixels 23 can be tighter, 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 where a wiring portion or a transistor portion of each pixel 23 is removed (normally hidden by a black matrix) and an area of the entire pixel 23. The higher the aperture ratio, the higher the efficiency of light passing.
In this embodiment, the first center line 2301 of each pixel 23 in the display panel 20 is specifically parallel to the third direction, so that each pixel 23 is closer to the adjacent data line 21, and each two adjacent pixels 23 can be closer to each other, so that the arrangement of the corresponding pixels 23 can be tighter, the density of the pixels 23 is increased, and the aperture ratio of the display panel 20 can be effectively increased.
It is 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 respectively 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, and specific reference is made to fig. 1, fig. 2, fig. 3 and related text, which are not repeated herein.
Further, the present application also protects an array substrate, for example, the array substrate described in any of the above embodiments. In fact, the above embodiments can 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, and the plurality of scan lines and the plurality of data lines intersect with each other to define a plurality of pixel regions, and the plurality of pixels are respectively and correspondingly disposed in the plurality of pixel regions, wherein the plurality of scan lines are spaced in parallel with each other in a first direction, a first central line of each pixel forms a first included angle with the first direction, and the first included angle is greater than 0 and smaller than 90 °.
Fig. 6 is a schematic structural diagram of an embodiment of a display device according to the present application. The display device 31 includes a circuit substrate 311 electrically connected to each other and a display panel 312 disposed on the circuit substrate 311.
It should be noted that the circuit substrate 311 is specifically a circuit logic board for providing power and driving voltage for the display panel 312 and electrically connecting with an external device or apparatus, and the display panel 312 described in this embodiment is the display panel 10 or the display panel 20 described in any of the above embodiments, which is not described herein again.
