Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.
Fig. 1A illustrates a pixel arrangement method for original RGB display, in which each pixel unit 100 includes RGB three primary color sub-pixels, and the three primary color sub-pixels are sequentially arranged, and an AMOLED with PPI above 300 cannot be realized due to large occupied space of the original RGB display. FIG. 1B shows a conventional method for merging the same sub-pixels in adjacent pixel units, such as pixel units 101 and 102 share adjacent sub-pixel R, but the visual effect is not very good because the G sub-pixel is too close due to the conventional method for merging the adjacent sub-pixels.
Based on this, the present embodiment provides a display method of pixel arrangement for calculating the luminance value of each sub-pixel. It should be noted that the pixel arrangement of the present embodiment is based on a Diamond pentale pixel arrangement, as shown in fig. 2, the Diamond pentale pixel arrangement is to form a target pixel unit by sharing a first sub-pixel 200 (e.g., a B sub-pixel in fig. 2) or a second sub-pixel 300 (e.g., an R sub-pixel in fig. 2) with two laterally adjacent pixel units. Several target pixel units (including the shared first sub-pixel 200 or second sub-pixel 300 and third sub-pixel 400) are arranged in rows and columns to form a pixel arrangement of Diamond pentale. Wherein the third sub-pixel 400 (e.g., the G sub-pixel in fig. 2) has a center coinciding with the center of the virtual square VS; a first subpixel 200 spaced apart from the third subpixel 400 and having a center P1 at a first vertex of the virtual square; and a second subpixel 300 spaced apart from the first subpixel 200 and the third subpixel 400 and having a center P2 at a second vertex adjacent to the first vertex P1 of the virtual square.
In the embodiment, each target pixel unit comprises two three-primary-color sub-pixel units which are adjacent in the horizontal direction and are composed of one R sub-pixel, one B sub-pixel and two G sub-pixels which are arranged at four vertexes of a parallelogram, wherein the R sub-pixel and the B sub-pixel are arranged at intervals in the horizontal direction and the vertical direction. Therefore, the display method of the present embodiment may be used to calculate the target luminance values of the respective sub-pixels (the R sub-pixel, the B sub-pixel, and the two G sub-pixels) in the target pixel unit of the pixel arrangement, as shown in fig. 3, and may include the steps of:
step S302, obtaining the original luminance values of the three primary color sub-pixels of each three primary color sub-pixel unit in the target pixel unit.
In the present embodiment, the three primary color sub-pixels include an R sub-pixel, a B sub-pixel, and a G sub-pixel. The three primary color sub-pixels constitute an original RGB pixel unit, and the original luminance values of the three primary color sub-pixels refer to the luminance values of the RGB three primary color sub-pixels in fig. 1A, which can be obtained by the gray scale of each sub-pixel. After the original RGB three primary color sub-pixels in fig. 1A are converted into the Diamond pentale pixel arrangement in fig. 2, the target luminance values of the sub-pixels (R sub-pixel, B sub-pixel, and two G sub-pixels) in the target pixel unit corresponding to the Diamond pentale pixel arrangement should be correspondingly adjusted to achieve uniform display and achieve better visual effect. In this embodiment, the target luminance values of the sub-pixels (R sub-pixel, B sub-pixel, and two G sub-pixels) in the target pixel unit can be specifically calculated according to the original luminance values of the three primary color sub-pixels in the original RGB pixel unit, and therefore, the original luminance values of the three primary color sub-pixels in the original RGB pixel unit in the Diamond Pentile pixel arrangement need to be obtained first.
In step S304, half of the original luminance value of the G sub-pixel is used as the target luminance value corresponding to the G sub-pixel.
In the present embodiment, since the R and B sub-pixels can be shared in the manner of the Diamond Pentile pixel arrangement, the total number of the R and B sub-pixels is equal to the total number of the G sub-pixels. Therefore, the PPI thereof finally depends on the G sub-pixels having a large arrangement density and uniform distribution. Since two pixel units adjacent in the transverse direction can share the R sub-pixel and the B sub-pixel, in order to achieve uniform display, the luminance value of the G sub-pixel can be reduced to half as the target luminance value, that is, the target luminance value of the G sub-pixel is half of the original luminance value, so as to achieve a better visual effect.
In step S306, it is determined whether the R or B sub-pixel is located in the first row of the pixel arrangement. If yes, go to step S308, otherwise go to step S310.
In this embodiment, since the target luminance value of the G sub-pixel has been determined through the above steps, it is necessary to further determine the target luminance values of the R sub-pixel and the B sub-pixel in the manner of the Diamond Pentile pixel arrangement. In addition, in this pixel arrangement, since the R sub-pixel and the B sub-pixel arranged in the first column are not shared, and the R sub-pixel and the B sub-pixel arranged in other positions are shared, in order to achieve uniform display, different processing is required for the target luminance of the shared and unshared R sub-pixel or B sub-pixel, and therefore, it is necessary to further determine the position of the R sub-pixel or B sub-pixel in the pixel arrangement, that is, to determine whether the R sub-pixel or B sub-pixel is in the first column of the pixel arrangement.
In step S308, half of the original luminance value of the R or B sub-pixel is taken as the corresponding target luminance value.
In the present embodiment, if it is determined that the R sub-pixel or the B sub-pixel is located at the head column position of the pixel arrangement, it can be considered that the R sub-pixel or the B sub-pixel is not shared. Therefore, in order to achieve uniform display, the target brightness of the R or B sub-pixel located at the first column of the pixel arrangement may be half-brightened, that is, half of the original brightness value of the R or B sub-pixel located at the first column of the pixel arrangement is used as the target brightness value of the corresponding R or B sub-pixel, so as to avoid over-brightness of the edge and achieve a better visual effect.
Step S310, determining a target luminance value corresponding to the R sub-pixel or the B sub-pixel according to an original luminance value of a target pixel unit where the R sub-pixel or the B sub-pixel is currently located and three primary color sub-pixel units which are laterally adjacent and share the R sub-pixel or the B sub-pixel.
In this embodiment, if it is determined that the R sub-pixel or the B sub-pixel is not located in the head column of the pixel arrangement, it may be considered that the R sub-pixel and the B sub-pixel are to be shared, and therefore, it is necessary to further determine the target luminance value thereof according to the sharing condition of the R sub-pixel and the B sub-pixel. Specifically, in the present embodiment, the target luminance value thereof may be determined by the original luminance values of the R sub-pixel or the B sub-pixel in all the three primary color sub-pixel units sharing the R sub-pixel or the B sub-pixel. Namely, the target brightness value corresponding to the R sub-pixel or the B sub-pixel is calculated according to the original brightness value of the target pixel unit where the R sub-pixel or the B sub-pixel is located currently and the original brightness values of the three primary color sub-pixel units which are adjacent in the transverse direction and share the R sub-pixel or the B sub-pixel, so that the visual effect is improved, and uniform display is realized.
In an embodiment, the target luminance value corresponding to the R sub-pixel or the B sub-pixel is determined according to the original luminance values of the target pixel unit where the R sub-pixel or the B sub-pixel is currently located and three primary color sub-pixel units which are laterally adjacent and share the R sub-pixel or the B sub-pixel, and the following method may be specifically adopted for calculation:
specifically, if it is determined that the R sub-pixel or the B sub-pixel is not located at the first column position of the pixel arrangement, it may be further determined whether the target pixel unit where the R sub-pixel or the B sub-pixel is currently located is located in the first target pixel unit arranged laterally; if it is determined that the pixel unit where the R sub-pixel or the B sub-pixel is currently located is located in the first target pixel unit arranged laterally, the target brightness value of the corresponding R sub-pixel or B sub-pixel in the row may be calculated by the following formula: and LumX (j) '(LumX (j × 2-1) + LumX (j × 2))/2, where LumX ()' represents a target luminance value corresponding to a subpixel in the target pixel unit, LumX () represents an original luminance value of a corresponding subpixel in the three primary color subpixel units, X is R or B, j is a column index of the target pixel unit to which the subpixel belongs, j ═ 1 or k, and k is the total column number of the target pixel unit.
For example, assume that the pixel arrangement based on Diamond Pentile is as shown in fig. 4, wherein the first row of corresponding three-primary-color sub-pixel units includes four columns of a1, a2, a3 and a4, and assume that the three-primary-color sub-pixels in a4 include R4, B4 and G4, which correspond to R4, B4 and G4 in fig. 4, and the three-primary-color sub-pixels in a4 include R4, B4 and G4, which correspond to R4, B4, G4 and G4 in fig. 4.
Therefore, a shared sub-pixel B11 exists between a1 and a2, a shared sub-pixel R12 exists between a2 and a3, and a shared sub-pixel B12 exists between a3 and a 4. For the pixel cell composed of a1 and a2, it actually includes only R11, G11, B11 and G12. Therefore, a1 and a2 jointly constitute the target pixel unit 400, and thus, in the present embodiment, the pixel arrangement shown in fig. 4 includes three rows and three columns of matrix-shaped target pixel units, that is, the pixel arrangement shown in fig. 4 includes three primary color sub-pixel units in a matrix of three rows and four columns. Wherein the sub-pixel in each target pixel unit 400 can pass through XijWhere X is the corresponding subpixel R, B or G, i is the subscript of the line where the target pixel unit to which the subpixel R, B or G belongs is located, i is 1 or n, and n is the total number of lines of the target pixel unit. j is a column index of a target pixel unit to which the subpixel R, B or G belongs, j is 1 or k, and k is the total column number of the target pixel unit.
From the above method, it can be seen that for all the G sub-pixels (i.e. all the G sub-pixels) in the pixel arrangement of the present embodimentij) Half-bright processing is performed (therefore, only G is shown in the figure, and subscripts thereof are omitted) for all R and B sub-pixels arranged at the top column positions in the pixel arrangement(i.e., R in FIG. 4)11、B21And R31) And carrying out half-bright processing.
Also explained in the above embodiment, for B11, since it is shared by two three primary color sub-pixel units a1 and a2, the target luminance value of B11', i.e., B11, can be determined by the original luminance value of B1 in the three primary color sub-pixel unit a1 and the original luminance value of B2 in the three primary color sub-pixel unit a 2. Specifically, as can be seen from the determination method of the present embodiment, the target luminance value of the corresponding sub-pixel can be determined according to the position of the sub-pixel B11 specifically in the pixel arrangement.
In this embodiment, it may be determined whether the pixel unit where other R sub-pixels or B sub-pixels are currently located in the pixel arrangement is located in the first target pixel unit arranged laterally, that is, whether the column subscript of the other R sub-pixels or B sub-pixels is 1.
Also illustrated in fig. 4, for example, for B11, which belongs to the sub-pixel in the first column of the target pixel unit in the first row and has a column index of 1, the target brightness value corresponding to the B11 sub-pixel is calculated by substituting the above formula, that is:
LumB(1,1)’＝(LumB(1,(1*2-1))+LumB(1,1*2))/2
＝(LumB(1,1)+LumB(1,2))/2
(LumB1+ LumB2)/2 (the row number subscript is omitted here, and since there is only a horizontal sharing relationship in this embodiment, the target luminance values of the corresponding R or B sub-pixels in the same row are calculated, and thus the row subscripts are the same in the calculation process, and thus they may be omitted). Where, LumB (1, 1)' represents a target brightness value corresponding to the subpixel B11 in the target pixel unit, LumB1 represents an original brightness value corresponding to the subpixel B1 in the three-primary subpixel unit, and LumB2 represents an original brightness value corresponding to the subpixel B2 in the three-primary subpixel unit. Also, the target luminance value of other B sub-pixels in the row, for example, the target luminance value of B12, can also be calculated by the formula:
LumB(1,2)’＝(LumB(1,(2*2-1))+LumB(1,2*2))/2
＝(LumB(1,3)+LumB(1,4))/2
where, lumib (1, 2)' represents a target luminance value corresponding to subpixel B12 in the target pixel unit, lumib 3 represents an original luminance value corresponding to subpixel B3 in the three-primary-color subpixel unit, and lumib 4 represents an original luminance value corresponding to subpixel B4 in the three-primary-color subpixel unit.
In one embodiment, if it is determined that the R sub-pixel or the B sub-pixel is not located at the top column position of the pixel arrangement and it is determined that the R sub-pixel or the B sub-pixel corresponds to the sub-pixel at the top column position of its lateral arrangement, the target luminance value of the corresponding R sub-pixel or B sub-pixel in the row is calculated by the following formula: and LumX (j) '(LumX ((j-1) × 2) + LumX ((j-1) × 2+1))/2, wherein LumX ()' represents a target luminance value corresponding to a subpixel in the target pixel unit, LumX () represents an original luminance value of a corresponding subpixel in the three primary color subpixel unit, X is an R or B subpixel, j is a column index of the target pixel unit to which the subpixel belongs, j ═ 2 or k, and k is the total column number of the target pixel unit.
Also illustrated in FIG. 4 is an example, such as for subpixel R12It belongs to the sub-pixel in the first row which is not in the first column position of the pixel arrangement, as can be seen from fig. 4, the sub-pixel R in the first column position of the row11And the R is12Belonging to the R sub-pixel, so that the sub-pixel R can be determined12Corresponding to the sub-pixels in the first row arranged laterally, and substituting the above formula to calculate R12The target luminance value corresponding to the sub-pixel is:
LumR(1,2)’＝(LumR(1,(j-1)*2)+LumR(1,(j-1)*2+1))/2
＝(LumR(1,2)+LumR(1,3))/2
(LumR 2+ LumR 3)/2. Where LumR (1, 2)' denotes a subpixel R in a target pixel unit12And the corresponding target brightness value, LumR (1,2), represents the original brightness value corresponding to the subpixel R2 in the three-primary-color subpixel unit, and LumR3 represents the original brightness value corresponding to the subpixel R3 in the three-primary-color subpixel unit.
