First, the present invention provides a display panel, and specifically, referring to fig. 1, fig. 1 is a schematic structural diagram of a display panel according to an embodiment of the present invention, wherein the display panel 100 includes a display area AA and a non-display area BB at least located on one side of the display area AA or disposed around the display area AA. The display area AA comprises at least one shaped border S1 arranged adjacent to the non-display area BB.
The display panel 100 further includes a plurality of pixel units 10 located in the display area AA, wherein the plurality of pixel units 10 are arranged along a first direction D1 to form a pixel row, and arranged along a second direction D2 to form a pixel column. Each pixel unit 10 includes a first sub-pixel 11 and a second sub-pixel 12 arranged along a first direction D1. Wherein the first direction D1 intersects the second direction D2, and the shaped boundary S1 intersects the first direction D1 and the second direction D2, respectively, in the extending direction thereof.
In the present embodiment, the boundary line between the display area AA and the non-display area BB of the display panel 100 is a shape including an arc line, for example, the display area of the display panel is a rounded rectangle (the partial boundary at the four corners thereof is the shape of the arc line), and the non-display area BB has a shaped non-display area BB1 at a position near the rounded corner thereof, and the shaped boundary S1 is located between the shaped non-display area BB1 and the display area AA. Alternatively, the display area AA of the display panel 100 includes a cut-out for placing a camera or an earphone, the special-shaped non-display area BB1 is located between the cut-out and the display area AA, and the special-shaped boundary S1 is located between the special-shaped non-display area BB1 and the display area AA. Alternatively, the display area AA of the display panel 100 has a non-rectangular shape, such as a diamond shape, an oval shape, a hexagon shape, or a triangle shape, which also generates a special-shaped boundary (in this case, the boundary of the display area, even if it is a straight line, intersects both the first direction D1 and the second direction D2, or intersects both the pixel rows and the pixel columns, but is not parallel to the pixel rows or the pixel columns).
The plurality of pixel cells 10 includes an edge pixel cell 10S and a normal pixel cell 10A, the edge pixel cell 10S being disposed adjacent to the odd-shaped boundary S1, the normal pixel cell 10A being located on a side of the edge pixel cell 10S away from the odd-shaped boundary S1. In other words, among the plurality of pixel cells 10, the edge pixel cell 10S is disposed adjacent to the irregular boundary S1, and the normal pixel cell 10A is not disposed adjacent to the irregular boundary S1. In each edge pixel unit 10S, the first sub-pixel neighborhood 11 is disposed adjacent to the shaped boundary S1, and the second sub-pixel 12 is disposed on a side of the first sub-pixel 11 away from the shaped boundary S1, specifically, in the embodiment, the first sub-pixel 11 and the second sub-pixel 12 are arranged along the first direction D1, and the second sub-pixel 12 is disposed between the first sub-pixel 11 and the shaped boundary S1 in the first direction D1.
The display brightness of the second sub-pixel 12 is greater than the display brightness of the first sub-pixel 11. The brightness refers to the physical quantity of the intensity of the light emitted (reflected) from the surface of the illuminant (reflector), and the ratio of the light intensity in one direction when the human eye observes the light source to the area of the light source "seen" by the human eye is defined as the brightness of the light source unit, i.e. the light intensity in the unit of projection area. Brightness, also known as lightness, represents the brightness of a color, and the brightness perceived by the human eye is determined by the reflected or transmitted light of the color. In the embodiment of the present invention, the display luminance is the luminance that the human eye perceives from one direction as each sub-pixel driven by the gray-scale data signal. At this time, in each pixel unit, the difference of the display luminance of the first sub-pixel 11 and the second sub-pixel 12 may be caused by one or more reasons, for example, may be caused by the difference of the gray scale data signals of the first sub-pixel 11 and the second sub-pixel 12; may be caused by the difference in the aperture ratio of the first sub-pixel 11 and the second sub-pixel 12; the shape of the driving electrode in the first sub-pixel 11 may be different from that of the driving electrode in the second sub-pixel 12 (the driving electrode in each sub-pixel, such as the pixel electrode or the common electrode, has different shapes and sizes, which may cause different driving capacities of the sub-pixels), or the light transmittance of the first sub-pixel 11 may be different from that of the second sub-pixel 12, or the driving electrode may be a combination of several reasons, which is not limited in this embodiment.
In the embodiment of the invention, in each edge pixel unit, the sub-pixel with lower display brightness is arranged near the special-shaped boundary, so that the brightness difference between the sub-pixel closest to the special-shaped boundary and the non-display area can be reduced, and the edge saw-tooth feeling near the special-shaped boundary of the display panel can be further reduced.
Fig. 2 is a partial schematic structural diagram of another display panel according to an embodiment of the present invention, in the display panel provided in fig. 2, each pixel unit 10 includes a first sub-pixel 11, a second sub-pixel 12, and a third sub-pixel 13 arranged along a first direction D1. In each edge pixel unit 10S, the first sub-pixel neighborhood 11 is disposed adjacent to the shaped boundary S1, the second sub-pixel 12 is located on a side of the first sub-pixel 11 away from the shaped boundary S1, and the third sub-pixel 13 is located on a side of the second sub-pixel 12 away from the shaped boundary S1, wherein the display luminance of the second sub-pixel 12 is greater than the display luminance of the first sub-pixel 11, and the display luminance of the third sub-pixel 13 is greater than the display luminance of the second sub-pixel 12.
In each edge pixel unit 10S, the display luminance of the third sub-pixel 13, the second sub-pixel 12, and the first sub-pixel 11 decreases in a stepwise manner, and the display luminance of the sub-pixel closer to the irregular boundary decreases, which can further reduce the edge jaggy feeling in the vicinity of the irregular boundary of the display panel.
In the display panel shown in fig. 2, the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 have different colors in each pixel unit, and may be three primary colors (blue, red and green), for example. The arrangement and the arrangement sequence of the three sub-pixels in the normal pixel unit 10A are the same as those of the three sub-pixels in the edge pixel unit 10S, or the arrangement of the sub-pixels in all the pixel units 10 is the same, and the color of the adjacent sub-pixels is different in each pixel row. For example, in each pixel row, the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 may be sequentially arranged in a cycle order to form one pixel row. Of course, it may be: the arrangement of the three sub-pixels in the normal pixel unit 10A is different from the arrangement of the three sub-pixels in the edge pixel unit, for example, in each pixel row, along the direction from the position adjacent to the special-shaped boundary S1 toward the direction away from the special-shaped boundary S1, the arrangement of the three sub-pixels in the edge pixel unit 10S is: a first subpixel 11, a second subpixel 12, and a third subpixel 13; the arrangement of the three sub-pixels in each conventional pixel unit 10A is: a second sub-pixel 12, a third sub-pixel 13, and a first sub-pixel 11. As long as "the colors of the adjacent sub-pixels in each pixel row are different" is satisfied.
Further, in the present embodiment, the plurality of pixel units 10 are arranged along the first direction D1 to form pixel rows, and arranged along the second direction D2 to form pixel columns, the display panel includes a plurality of pixel rows and a plurality of pixel columns, the plurality of pixel rows includes an x-th pixel row and an x + 1-th pixel row which are adjacent to each other, at an end of the pixel row near the irregular boundary S1, the x-th pixel row is retracted by 1 edge pixel unit relative to the x + 1-th pixel row, where x is an integer greater than or equal to 1, or there is an integer or several integer pixel units between two adjacent rows, so that the edge color shift phenomenon of the display area can be improved.
Fig. 3 is a schematic partial structure diagram of another display panel according to an embodiment of the invention, in the display panel provided in fig. 3, a plurality of pixel units are arranged along a first direction D1 to form pixel rows, and are arranged along a second direction D2 to form pixel columns, each pixel unit includes a first sub-pixel 11, a second sub-pixel 12, and a third sub-pixel 13 arranged along a first direction D1, and the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are a blue sub-pixel, a red sub-pixel, and a green sub-pixel, respectively. Along the direction from the position adjacent to the special-shaped boundary S1 to the position far away from the special-shaped boundary S1, the arrangement mode of the three sub-pixels in the edge pixel unit is as follows: a first subpixel 11, a second subpixel 12, and a third subpixel 13; the arrangement of three sub-pixels in each conventional pixel unit is as follows: a second sub-pixel 12, a third sub-pixel 13, and a first sub-pixel 11.
In the embodiment of the present invention, the display panel may be a liquid crystal display panel, an organic light emitting display panel, a direct type nanowire light emitting diode display panel, or other types of display panels, which is not limited in this embodiment. Referring to fig. 3 and fig. 4 and fig. 5, fig. 4 is a cross-sectional view taken along a direction a1-a2 in fig. 3, and fig. 5 is a schematic view of a portion of a pixel structure of an array substrate in the display panel shown in fig. 3. In this embodiment, the display panel 100 includes a color film substrate 110, an array substrate 120, and a liquid crystal molecular layer 130 located in a sealed box-shaped space formed by the color film substrate 110 and the array substrate 120.
The array substrate 120 includes a plurality of pixel units 10 arranged in an array along a first direction D1 and a second direction D2, each pixel unit 10 includes three sub-pixels arranged along a first direction D1, each sub-pixel includes an opening area 101 and a light-shielding area 102, each sub-pixel is further provided with a thin film transistor T serving as a driving switch, a gate line GL extending from a gate of the thin film transistor T and a data line DL extending from a drain, and the thin film transistor T, the gate line GL and the data line DL are located in the light-shielding area 102. The source of the thin film transistor T is connected to a pixel electrode 121, the pixel electrode 121 is a transparent conductive electrode, is located in the opening area 101, and supplies a gray-scale data signal to each sub-pixel, and the gate lines GL and the data lines DL cross to form a plurality of sub-pixels.
The color filter substrate 110 includes a color filter layer 111, the color filter layer 111 includes color resistors F having different colors and a black matrix BM located between adjacent color resistors F, and the opening area 101 of each sub-pixel is disposed corresponding to one of the color resistors F. In the present embodiment, the opening areas 101 of the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 respectively correspond to the blue color resist, the red color resist and the green color resist on the color film 111, so as to form a blue sub-pixel capable of displaying blue, a red sub-pixel capable of displaying red and a green sub-pixel capable of displaying green. The light-shielding region 102 of each sub-pixel corresponds to the black matrix BM, or the black matrix BM covers the gate line GL, the data line DL and the thin film transistor T on the array substrate 120 in a direction perpendicular to the display panel, and the black matrix BM covers the non-display region of the display panel, or the light-shielding layer for preventing light leakage in the non-display region may be formed of the same material as the black matrix BM. When displaying, light passes through the color resistors F, so that each sub-pixel presents the same color as the corresponding color resistor F, and the sub-pixels with different colors are repeatedly arranged in an array, thereby realizing different color combinations.
It should be noted that each sub-pixel may further include a common electrode 122 located on the array substrate 120, an alignment film (not shown) located on the array substrate 120, and an alignment film (not shown) located on the color film substrate 110, and further, since the above structures are structures of display panels known to those skilled in the art, they are not described herein again. During display, liquid crystal molecules in the liquid crystal molecular layer 130 rotate or twist under the action of a driving electric field provided by the pixel electrode and the common electrode, so that the backlight passes through the opening area of each sub-pixel, then passes through the liquid crystal molecular layer 130 between the array substrate 120 and the color film substrate 110, and is emitted by the color resistor F corresponding to the sub-pixel, thereby realizing a display function.
In the present embodiment, the areas of the opening areas of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 on the array substrate 120 are equal, but when the same gray-scale data signal is supplied to the three sub-pixels, the display luminance of the three sub-pixels finally irradiated to the human eye is different. This is because: the three sub-pixels display different colors because light passes through three color resistors of different colors, and the color resistor is an optical filter for expressing colors, which can precisely select light of a small range of passing bands and reflect light of other bands. For example, the blue color resistance only allows light in a blue visible light band to pass, the red color resistance only allows light in a red visible light band to pass, the green color resistance only allows light in a green visible light band to pass, and the transmittance of the light in the blue visible light band, the light in the red visible light band, and the light in the green visible light band in the polyimide film (alignment film), the planarization layer, the coating layer (OC), and other film layers in the display panel is different, so that the light quantities of the finally emitted blue light, red light, and green light are different, and finally, the display brightness of the three sub-pixels is different. Further, the human eye has different sensitivities, or sensitivities, to different wavelengths of radiation within the visible spectrum, wherein the human eye has the highest sensitivity to the yellow-green visible light band and the lowest sensitivity to the blue visible light band. This finally results in: when the areas of the opening areas of the three sub-pixels on the array substrate are equal and the same gray-scale data signals are transmitted to the three sub-pixels, the display brightness of the three sub-pixels actually sensed by human eyes is different, wherein the display brightness of the green sub-pixel is the highest, the display brightness of the red sub-pixel is the second highest, and the display brightness of the blue sub-pixel is the lowest.
In this embodiment, in each edge pixel unit, the blue sub-pixel with the lowest display brightness is disposed adjacent to the special-shaped boundary, the red sub-pixel with the middle display brightness is slightly distant from the special-shaped boundary, and the green sub-pixel with the highest display brightness is farthest from the special-shaped boundary. In other words, in each pixel row intersecting the irregular boundary, all the sub-pixels arranged adjacent to the irregular boundary are blue sub-pixels with the lowest display brightness, the display brightness of the three sub-pixels of the edge pixel unit is sequentially reduced in a step shape, and the display brightness of the sub-pixels closer to the irregular boundary is lower, so that the brightness difference between the sub-pixels and the non-display area can be further reduced, and the edge jaggy feeling near the irregular boundary of the display panel can be improved. In addition, in the embodiment, the purpose of reducing the jaggy feeling of the edge near the special-shaped boundary of the display panel can be realized only by adjusting the arrangement sequence of the three sub-pixels in the edge pixel unit without changing the opening area of the sub-pixels, the pixel electrode formation, the integrated driving circuit for providing the gray-scale data signal and the like, and the realization method is simple and the cost is low.
In this embodiment, the arrangement of the three sub-pixels in the normal pixel unit is different from the arrangement of the three sub-pixels in the edge pixel unit, but it is also possible to arrange the sub-pixels in all the pixel units in the same arrangement.
