Description

Technical Field of the InventionThe present invention relates to the field of 3D display technologies, and more particularly to an array substrate, a 3D display panel, and a 3D display device.BACKGROUND OF THE INVENTIONStereo display technologies can be broadly classified into the stereo display glasses technology and the automatic stereo display technology in which a specially designed viewing device (e.g., specially designed glasses or helmets) does not need to be worn to effect the automatic stereoscopic display, and also referred to as stereo displays for the naked eye. In the technology of stereoscopic displays for the naked eye, the same image is projected into the left eye and the right eye of a viewer using a grating device, respectively, and different parallaxes for the image projected into the left eye and the right eye cause stereoscopic display. Specifically, taking a slit grating as an example, there is a distance between the grating and a 3D display panel, so that different combinations of pixels can be seen from the left and right eyes, respectively, through slits, and thus different images are projected into the left and right eyes, as illustrated in FIG. 1A.However, the gaps of the slit grating may be disposed in an area having more display zones or in an area having more non-display zones, and when the gaps of the slit grating are disposed in the area having more display zones, a brighter display effect may be exhibited in the area, and when the gaps of the slit grating are disposed in the area having more non-display zones, a darker display effect may be exhibited in the area, so that lighter and darker stripes, i.e., moire stripes, tend to appear in the overall display effect alternately.In the aforementioned technology of stereo displays for the naked eye, the Moire fringes are typically mitigated by the following solution:In the display panel, a lateral shift, which is an irrational multiple of the width of a pixel unit, occurs for each row of pixel units on an array substrate relative to a previous row of pixel units, so that the ratio of display zones to non-display zones in the columns of the grid becomes more uniform to alleviate the Moire fringes.However, the inventors of the invention have recognized that in the above solution, a lateral shift, which is an irrational multiple of the width of a pixel unit, occurs every row of pixel units relative to a previous row of pixel units, so that the pixels may be arranged nonuniformly, resulting in periodic nonuniform brightness in the vertical direction (i.e., in the column direction). As illustrated in FIG. 1B, for respective rows of pixel units in the vertical direction and the same reference straight line L in this direction, row segment lengths formed from the respective pixel units R, G, and B intersecting the straight line are different. This also means that there are unequal display zones (which can be regarded as the line segments) for the respective pixel units R, G and B along the reference straight line L, for example, the pixel units R, G and B denoted by the reference numeral 1 appear reddish and the pixel units R, G and B denoted by the reference numeral 2 appear greenish, so that there may be non-uniform brightness of the pixel units R, G and B in the direction in which the straight line runs, resulting in Moire stripes and affecting a display effect.US 2012 / 0229456 A1 discloses a three-dimensional display device having a pair of substrates having a plurality of pixels arranged in a matrix in a display region. The parallelogram pixels are arranged in rows and can have a different height. A further three-dimensional display device is disclosed in US 2011 / 0141560 A1.SUMMARY DESCRIPTION OF THE INVENTIONAn object of the invention is to provide an array substrate, a 3D display panel and a 3D display device for making the brightness of respective R / G / B pixel units uniform in the vertical direction, mitigating the moire fringes and improving a 3D display effect.The object of the invention is achieved with an array substrate having the features of claim 1.An embodiment of the invention provides an array substrate including a plurality of sub-pixel units arranged in an array form, wherein each of the sub-pixel units is a non-equilateral parallelogram, wherein the top and bottom of each of the sub-pixel units are shorter sides of the non-equilateral parallelogram, and wherein the same rows of corresponding sub-pixel units are inclined in the same direction, wherein the top sides of the corresponding sub-pixel units in the same row of sub-pixel units lie on a straight line, wherein the bottom sides of the corresponding sub-pixel units lie on a straight line, wherein the projection of the top side of each of the sub-pixel units in the vertical direction lies overlapping on the bottom side of an adjacent sub-pixel unit, and wherein the projection of the bottom side of the sub-pixel unit in the vertical direction lies overlapping on the top side of another adjacent sub-pixel unit, and wherein, for any two of the sub-pixel units (201), a straight line perpendicular to the top of one of the two sub-pixel units (201) intersects an end of the top and a long side of one of the two sub-pixel units (201) opposite the end to form a first row segment, and a straight line perpendicular to the top of the other of the two sub-pixel units (201) intersects an end of the top and a long side of the other of the two sub-pixel units (201) opposite the end to form a second row segment, wherein a length of the first row segment is equal to the length of the second row segment, and wherein the end is the apex of an obtuse angle adjacent to the top.The embodiment of the invention provides the following advantageous effects: the same rows of sub-pixel units are inclined in the same direction, and the projection of the top of each sub-pixel unit in the vertical direction is overlapped on the bottom of an adjacent sub-pixel unit, and the projection of the bottom of the sub-pixel unit in the vertical direction is overlapped on the top of another adjacent sub-pixel unit, resulting in a more uniform ratio of display zones and non-display zones in columns of a grid when cooperating with the grid and a periodically uniform brightness in the vertical direction (i.e., in the column direction), mitigating Moire fringes, and improving a 3D display effect.An embodiment of the invention provides a 3D display panel comprising two paired box substrates and liquid crystals arranged between the two paired box substrates, wherein one of the two paired box substrates is the array substrate according to the aforementioned embodiment of the invention.The embodiments of the invention provide the following advantageous effects: the same rows of sub-pixel units are inclined in the same direction, and the projection of the top of each sub-pixel unit in the vertical direction is overlapping on the bottom of an adjacent sub-pixel unit, and the projection of the bottom of the sub-pixel unit in the vertical direction is overlapping on the top of another adjacent sub-pixel unit, resulting in periodic uniform brightness in the vertical direction (i.e., in the column direction), mitigating Moire fringes, and improving 3D display effect.An embodiment of the invention provides a 3D display device including a grid configured to project different images into the left eye and the right eye, respectively, wherein the 3D display device includes the 3D display panel according to the aforementioned embodiment of the invention.The embodiments of the invention have the following advantageous effects: resulting in a more uniform ratio of display zones to non-display zones of the pixel array in columns of the grid, periodically uniform brightness in the vertical direction (i.e., in the column direction), mitigation of Moire fringes and improvement of a 3D display effect.Brief Description of the DrawingsFIGS. 1A and 1B are schematic structural diagrams of an array substrate for a 3D display according to the related art, FIG. 2 is a schematic structural diagram of an array substrate according to an embodiment of the invention, FIG. 3 is a schematic structural diagram of sub-pixel units according to an embodiment of the invention, FIG. 4 is a schematic structural diagram of two sub-pixel units having different heights according to an embodiment of the invention, FIG. 5 is a schematic structural diagram of two sub-pixel units having the same height and different widths according to an embodiment of the invention;

However, a lateral shift, which is an irrational multiple of the width of a pixel unit, occurs for each row of pixel units relative to a preceding row of pixel units, so that the pixels may be arranged nonuniformly, resulting in periodic nonuniform brightness in the vertical direction (i.e., in the column direction), i.e., nonuniform brightness of the R / G / B pixel units in the zones in the vertical direction, so that moire fringes may occur. To mitigate the Moire fringes, embodiments of the invention provide an array substrate in which the structure of sub-pixel units is changed such that the ratio of display zones to non-display zones is uniform in columns of a grid and there is periodically uniform brightness in the vertical direction after arranging the grid. Hereinafter, implementations of the embodiment of the invention will be described with reference to the drawings. It should be noted that in all drawings, identical or similar reference numerals designate identical or similar elements or functionally identical or similar elements. The embodiments described below with reference to the drawings are for illustrative purposes and are intended merely to explain the invention, but should not be interpreted as limiting the invention.Reference is made to FIG. 2 which shows a schematic structure diagram of an array substrate according to an embodiment of the invention. An embodiment of the invention provides an array substrate including a plurality of sub-pixel units 201 arranged in the form of an array and black arrays 202 arranged between the sub-pixel units 201. The sub-pixel unit 201 is a non-equilateral parallelogram, wherein the top and bottom of the sub-pixel unit 201 are shorter sides of the non-equilateral parallelogram, and wherein the same rows of corresponding sub-pixel units 201 are inclined in the same direction.The top sides of the respective sub-pixel units 201 in the same row of sub-pixel units 201 lie on a straight line, the bottom sides of the respective sub-pixel units 201 lie on a straight line, the projection of the top side of each of the sub-pixel units 201 in the vertical direction overlapping lies on the bottom side of an adjacent sub-pixel unit 201, and the projection of the bottom side of the sub-pixel unit 201 in the vertical direction overlapping lies on the top side of another adjacent sub-pixel unit 201.For any two of the sub-pixel units 201, a straight line perpendicular to the tops of the two sub-pixel units 201 intersects an end of the top of each of the two sub-pixel units 201 and the side of each of the two sub-pixel units 201 opposite the end, respectively, to form equal line segments, the end being the vertex of the obtuse angle adjacent to the top.In an embodiment of the invention, a uniform brightness of the sub-pixel units 201 in the vertical direction is periodically given to mitigate the moire fringes and improve a 3D display effect.Reference is made to FIG. 3, which shows a schematic structural diagram of sub-pixel units according to an embodiment of the invention, wherein two adjacent sub-pixel units 201 and a black matrix 202 between the two adjacent sub-pixel units 201 are illustrated. The illustration shows an apex A, an apex B, an apex C and an apex D, and an apex A', an apex B', an apex C' and an apex D' of the two subpixel units 201, respectively. Preferably, the two sides of the sub-pixel unit 201 are two longer sides of the non-equilateral parallelogram, and the angle θ between the side of the sub-pixel unit 201 and a vertical line satisfies the following equation:Here, θ is the angle between the side of the sub-pixel unit 201 and the vertical line; L is 1 the length of the top or the bottom of the sub-pixel unit; W is the distance between two adjacent ends of the tops of the two adjacent sub-pixel units 201 or the distance between two adjacent ends of the bottoms of the two adjacent sub-pixel units 201; and H is the distance between the top and the bottom of the sub-pixel unit 201.The projection of the top AD of one of the sub-pixel units 201 in the vertical direction is fully overlapped on the bottom B'C' of the other sub-pixel unit 201 in the direction in which the sub-pixel units 201 are inclined, with the vertex A and the vertex B' lying on a vertical line. In an embodiment of the invention, the obtuse angle vertex formed by the top and side of one of the sub-pixel units 201 and the acute angle vertex formed by the bottom and side of the adjacent sub-pixel unit 201 lie on a vertical line in the direction in which the sub-pixel units are inclined. In the middle of a row of sub-pixel units 201, a vertical line can be placed at any locations of the row where there are equal valid display zones of the sub-pixel units 201 intersecting the vertical line, and with reference to, for example, Figure 3, a vertical line intersects a first sub-pixel unit 201 to create a row segment AK, and another vertical line intersects the two sub-pixel units 201 to create row segments MN and M'N', the length of the row segment AK being equal to the total length of the row segments MN and M'N'.Thus, there is a state in which, for any two sub-pixel units, a straight line perpendicular to the top surfaces of the two sub-pixel units 201 intersects an end of the top surface of each of the two sub-pixel units 201 and the side of each of the two sub-pixel units 201 opposite to the end, respectively, to form equal line segments, the end being the vertex of the obtuse angle adjacent to the top surface. A periodically uniform brightness of a subpixel array in the vertical direction may be given in the case that this condition is fulfilled for different rows of subpixel units 201. Reference may be made to FIGS. 4 and 5, which show schematic structural diagrams of sub-pixel units for the sake of more detailed description.Reference is made to FIG. 4, which shows a sub-pixel unit 2011 and a sub-pixel unit 2012 in different rows and with different heights, where vertices A 1, B 1, C 1 and D 1 of the sub-pixel unit 2011 and vertices A 2, B 2, C 2 and D 2 of the sub-pixel unit 2012 are located. The subpixel unit 2011 and the subpixel unit 2012 may or may not be located in adjacent rows. The height of the sub-pixel unit 2011 is H 1, the lengths of the top side A 1 D 1 and the bottom side B 1 C 1 are L 1, the distance from an adjacent sub-pixel unit is W 1, a straight line A 1 D 1 perpendicular to the top side runs through the vertex A 1 and intersects the side to form a line segment A1K1with a length h1, and the angle between the side A 1 B 1 and A 1 K 1 is θ 1; and the height of the subpixel unit 2012 is H 2, the lengths of the top side A 2 D 2 and the bottom side B 2 C 2 are L2, the distance from an adjacent subpixel unit is W2, a straight line perpendicular to the top side A2D2 passes through the vertex A2 and intersects the side, In order to form a row segment A 2 K 2 having a length h 2 and the angle between the side A 2 B 2 and A 2 K 2 is θ2, wherein L 1+ W 1 is equal to L 2+ W2.Reference is further made to FIG. 5, which shows a sub-pixel unit 2011 and a sub-pixel unit 2012 in different rows and with different heights, where vertices A 1, B 1, C 1 and D 1 of the sub-pixel unit 2011 and vertices A 2, B 2, C 2 and D 2 of the sub-pixel unit 2012 are located. The subpixel unit 2011 and the subpixel unit 2012 may or may not be located in adjacent rows. The height of the sub-pixel unit 2011 is H1, the lengths of the top side A 1 D 1 and the bottom side B1C1 are L1, the distance from an adjacent sub-pixel unit is W1, a straight line A1D1 perpendicular to the top side passes through the vertex A1 and intersects the side to form a line segment A1K1 having a length h1, and the angle between the side A1B1 and A1K1 is θ1; and the height of the sub-pixel unit 2012 is H2, the lengths of the top side A2D2 and the bottom side B2C2 are L2, the distance from an adjacent sub-pixel unit is W2, a straight line perpendicular to the top side A2D2 passes through the vertex A2 and intersects the side to form a row segment A2K2 having a length h2, and the angle between the side A2B2 and A2K2 is θ2, wherein H1 is H2, L1 is not L2, W1 is not W2, and L1+W1 is not L2+W2.According to the following equation (1) and equation (2), the following applies:The subpixel unit 2011 and the subpixel unit 2012 must satisfy the condition that h1 is h2. There are the following different arrangement combinations of sub-pixel units upon satisfying the condition that h1 is h2:For example, different rows of sub-pixel units may be arranged as illustrated in FIG. 4, where the heights H 1 and H 2 are different, the angles θ 1 and θ 2 are not equal, the widths L 1 and L 2 are not equal, and the distances W 1 and W 2 between all two adjacent sub-pixel units are not equal, but L 1+W 1 is L 2+W 2.In another example, different rows of sub-pixel units may be arranged as illustrated in FIG. 5, where the heights H 1 and H 2 are equal but the angles θ 1 and θ 2 are not equal, the widths L 1 and L 2 are not equal, and the distances W 1 and W 2 between all two adjacent sub-pixel units are not equal.In yet another example, different rows of sub-pixel units may be sub-pixel unit 2012 illustrated in FIG. 4 and sub-pixel unit 2012 illustrated in FIG. 5, where heights H 1 and H 2 are not equal, angles θ 1 and θ 2 are not equal, widths L 1 and L 2 are not equal, and distances W 1 and W 2 between all two adjacent sub-pixel units are not equal.In view of the above combinations of sub-pixel units, in an application to a display device having a grid and within a specified grid width, when m sub-pixel units 2011 as illustrated in FIG. 5 are arranged in one grid and n sub-pixel units 2012 as illustrated in FIG. 5 are arranged in another grid, L1+W1is not equal to L2+W2, so that m is not equal to n, where m and n are natural numbers. Of course, within a defined grid width there are as many subpixel units 2011 and subpixel units 2012, as illustrated in FIG. 4.It should be noted that the aforementioned embodiments are intended to illustrate only different combinations of sub-pixel units, but not to fully address combinations thereof, and that there may be numerous combinations that simultaneously satisfy the condition that h1is equal to h2for different rows of sub-pixel units, but are not enumerated here. Sub-pixel units and corresponding combinations of sub-pixel units that would occur to those skilled in the art without departing from the scope of the invention are within the scope of the invention as claimed.Preferably, the width of the black matrix 202 between two adjacent sub-pixel units 201 is equal to the width of the distance between the two adjacent sub-pixel units 201.Moreover, the sub-pixel units 201 are inclined in a direction that can be set row by row.For example, reference is made to FIG. 2, which illustrates a schematic structural diagram of the array substrate where all sub-pixel units 201 are tilted in the same direction, such that when the sub-pixel units 201 are shielded by a grid, the ratio of display zones to non-display zones in columns of the grid is uniform and there is a periodically uniform brightness of the resulting array of sub-pixels in the vertical direction.In another example, reference is made to FIG. 6, which illustrates a schematic structure diagram of another array substrate. A difference from the structure of the array substrate illustrated in FIG. 2 is that two adjacent rows of sub-pixel units 201 are inclined in opposite directions. Further, since respective sub-pixel units 201 in each row of sub-pixel units 201 are inclined in the same direction, the ratio of display zones to non-display zones in columns is uniform, and there is periodically uniform brightness of the formed array of sub-pixels in the vertical direction when two adjacent rows of sub-pixel units 201 are inclined in opposite directions.In yet another example, N adjacent rows of sub-pixel units 201 are a group of sub-pixel units 201 in which the sub-pixel units 201 are tilted in the same direction; and the sub-pixel units 201 in adjacent groups of sub-pixel units 201 are tilted in opposite directions, where N is an integer greater than or equal to 2. Referring to the array substrate illustrated in FIG. 6, this structure may be a variant of the array substrate illustrated in FIG. 6, so repeated illustration thereof will be omitted here. In this embodiment, the ratio of display zones to non-display zones is uniform in columns, and there is a periodically uniform brightness of the resulting array of sub-pixels in the vertical direction.In the respective aforementioned embodiments, the sub-pixel units 201 may be sub-pixel units of one pixel unit, or the sub-pixel units 201 may be formed by dividing one pixel unit into a plurality of zones capable of emitting light, or the sub-pixel units 201 may be formed by dividing one sub-pixel unit into a plurality of zones emitting light. The sub-pixel unit typically refers to an R, G, B, or W sub-pixel unit included in a pixel unit.It should be noted that in the respective aforementioned embodiments, the ratio of display zones to non-display zones may become more uniform in columns of a grid and there may be a periodically uniform brightness in the vertical direction (i.e., in the column direction) to alleviate the existing Moire fringes without any transverse displacement of each row of sub-pixel units 201 relative to a previous row of sub-pixel units 201. Of course, beyond the above embodiment, a transverse shift which is an irrational multiple of the width of one sub-pixel unit may exist for each row of sub-pixel units 201 relative to a previous row of sub-pixel units 201, without having any influence on the effect of the invention.The embodiments of the invention provide the following advantageous effects: the same rows of sub-pixel units are inclined in the same direction, and the projection of the top of each sub-pixel unit in the vertical direction is overlapping on the bottom of an adjacent sub-pixel unit, and the projection of the bottom of the sub-pixel unit in the vertical direction is overlapping on the top of another adjacent sub-pixel unit, resulting in periodic uniform brightness in the vertical direction (i.e., in the column direction), mitigating Moire fringes, and improving 3D display effect.An embodiment of the invention provides a 3D display panel comprising two paired box substrates and liquid crystals arranged between the two paired box substrates, wherein one of the two paired box substrates is the array substrate according to the aforementioned embodiment of the invention.The embodiment of the invention provides the following advantageous effects: the same rows of sub-pixel units are inclined in the same direction, and the projection of the top of each sub-pixel unit in the vertical direction is overlapped on the bottom of an adjacent sub-pixel unit, and the projection of the bottom of the sub-pixel unit in the vertical direction is overlapped on the top of another adjacent sub-pixel unit, resulting in periodic uniform brightness in the vertical direction (i.e., in the column direction), mitigating moire fringes, and improving a 3D display effect.An embodiment of the invention provides a 3D display device including a grid configured to project different images into the left eye and the right eye, respectively, and further including the 3D display panel according to the aforementioned embodiment of the invention.The embodiment of the invention has the following advantageous effects: resulting in periodically uniform brightness in the vertical direction (i.e., in the column direction), mitigation of Moire fringes, and improvement of 3D display effect.Obviously, various modifications and changes may be made to the invention by those skilled in the art without departing from the scope of the invention.
