Specific embodiment
Technology contents, construction feature, the objects and the effects for detailed description technical solution, below in conjunction with specific reality
It applies example and attached drawing is cooperated to be explained in detail.
Referring to Fig. 1, being a kind of panel method of sampling of the invention, include the following steps, S100 is with first on panel
Centered on sub-pixel, sampling mask block is established, S102 obtains the video data of the default display in sampling mask block, hides to sampling
The area set in cover block without video signal data bits is rejected, and is sampled to the video data of remaining position, S104 to sampled result into
Row normalized obtains the display result of first sub-pixel.For on visual theory, feedback of the human eye vision to color
It is the average value for the multiple light seen, brightness is if so, color.Based on such principle, the display panel of display is shouldered
The important process that vision is presented, display panel receives content to be shown (calling video data in the following text) while, due to solution
A variety of congenital reasons such as analysis degree, picture cutting, instead showing may make edge appearance sharpening, big color lump etc. a variety of indisposed strictly according to the facts
Show result.And through the above scheme, sampling mask block is established, the area of sampling mask block is greater than the area of sub-pixel, thus
Calculating is all normalized by all video datas in the size of sampling mask block, it is final to obtain reasonable display
As a result, it is possible to effectively solve the problems, such as marginal position poor display effect.
Above-mentioned method can equally apply in certain panels that pixel is the arrangement of matrix ranks, can also obtain preferably
Effect.In some other specific embodiment, the above method can obtain more preferably effect, and panel as shown in Figure 2 shows
In intention, pixel is in the panel of Delta arrangement, and right side shows partial enlarged view in figure, is can see in being located in enlarged drawing
Second sub-pixel of the heart, second sub-pixel is adjacent with the third sub-pixel of six different colours, third of different colours
Pixel divides top, lower section, upper left side, lower left, upper right side, the lower right of the second sub-pixel of column.Hexagonal arrangement architecture, and
Two kinds of colors are also divided between third sub-pixel, and mutually non-conterminous.The panel of this Delta arrangement can obtain in the application
Clearer display and higher resolution, but can not directly be shown by one-to-one mode, new sample mode is just
It is particularly important, we are by deleting the sampled result without video data area in sampling mask block, then to remaining
The sampled result of a block is normalized, and the coefficient in sampled result is relative area.Below by way of some examples into
Row explanation.
The video data schematic diagram that Fig. 3 illustrates as input, r (i, j) indicate the i-th row in input video data, jth column
The brightness of red sub-pixel, g (i, j) indicate the brightness of the i-th row, jth column green sub-pixels in input video data, b (i, j)
Indicate the brightness of the i-th row, jth column blue subpixels in input video data.Fig. 4 is panel sub-pixel actual arrangement schematic diagram, R
(m, n) indicate m row, the n-th column panel actual displayed red sub-pixel brightness, G (m, n) indicate m row, the n-th column panel
The brightness of the green sub-pixels of actual displayed, B (m, n) indicate m row, the n-th column panel actual displayed blue subpixels it is bright
Degree.Fig. 5 is mask (sampling mask block) schematic diagram, and mask is adjustable whole, can be by adjusting mask size come after adjusting sampling
Display effect.
And in the embodiment shown in fig. 6, it is shown that the method that SPR samples formula is calculated by mask, i.e., according to mask
The r (i, j) framed /g (i, j)/b (i, j) areal calculation goes out R (m, n)/G (m, n)/B (m, n) and r (i, j)/g (i, j)/b
Relationship between (i, j).
Derivation for marginal position sampling formula as shown in Fig. 7 a, Fig. 7 b, is shown by taking the first sub-pixel R (1,1) as an example
In the case of the mask for having shown two kinds of shapes, influence of the R (1,1) to input video data r (i, j) sampling.In Fig. 7 a, mask's
Length takes 4 times of the practical sub-pixel length of panel, and the width of mask takes 2 times of panel sub-pixel width；In Fig. 7 b, mask's
Length takes 4 times of the practical sub-pixel length of panel, and the width of mask takes 3 times of panel sub-pixel width.Those skilled in the art
It should be known that practical optional mask size is not limited to two kinds of 7a, 7b.
As shown in Figure 7a, according to mask r (i, j)/g (i, j)/b (i, the j) area framed it follows that
R (1,1)=x* [1/2*r (1,0)+1/2*r (1,1)+1/2*r (1,2)+r (2,0)+r (2,1)+r (2,2)+1/
2*r(3,0)+1/2*r(3,1)+1/2*r(3,2)]；
Since video data r (1,0), r (2,0), r (3,0) are not present, therefore taking the value of these three is 0, is obtained:
R (1,1)=x* [1/2*r (1,1)+1/2*r (1,2)+r (2,1)+r (2,2)+1/2*r (3,1)+1/2*r (3,
2)]；
It can be concluded that Fig. 7 a after normalized) in the first sub-pixel R (1,1) display result are as follows:
R (1,1)=1/8*r (1,1)+1/4*r (2,1)+1/8*r (3,1)+1/8*r (1,2)+1/4*r (2,2)+1/8*r
(3,2)；
Similarly it can be concluded that the sampling formula of the first sub-pixel R (1,1) in Fig. 7 b are as follows:
R (1,1)=1/6*r (1,1)+1/6*r (2,1)+1/6*r (3,1)+1/6*r (1,2)+1/6*r (2,2)+1/6*r
(3,2)。
In some other embodiment, realize that step comprises the following processes:
Step 1: the r (i, j) framed according to mask /g (i, j)/b (i, j) area obtains R (m, n)/G (m, n)/B
Relational expression between (m, n) and r (i, j)/g (i, j)/b (i, j)；
Step 2: by sampling when mask frame to the video data being not present take zero, obtain new R (m, n)/G (m, n)/
Relational expression between B (m, n) and r (i, j)/g (i, j)/b (i, j)；
Step 3: to the relational expression between new R (m, n)/G (m, n)/B (m, n) and r (i, j)/g (i, j)/b (i, j)
In r (i, j)/g (i, j)/b (i, j) before coefficient do normalized, obtain final R (m, n)/G (m, n)/B (m, n)
Sample formula.
Further include step in other specifically embodiment, judges whether the first pixel is located at face plate edge；Work as judgement
Be it is yes, just carry out step S100, centered on the first sub-pixel on panel, establish sampling mask block.Judge whether it is edge
Method include distance, pixel number etc., such as default edge thickness is several pixel numbers or isometric distance, such as 1-4 sub-pixel, In
Sub-pixel within the scope of this, which just carries out establishing mask when carrying out display sampling and obtains normalization, shows result, Er Fei
Sub-pixel within the scope of this, the method for sampling of not applicable the present invention program.By above-mentioned optimization, this hair is further increased
The display effect of the edge pixel of bright scheme.
The present invention program also introduces a kind of panel samples storage medium, is stored with computer program, the computer program
Following steps are executed when being run, and centered on the first sub-pixel on panel, are established sampling mask block, are obtained sampling mask
The video data of default display in block is rejected in sampling mask block without the area that video signal data bits are set, to remaining position
Video data is sampled, and sampled result is normalized, and obtains the display result of first sub-pixel.
Specifically, the panel is the panel of Delta arrangement, specifically, including the second sub-pixel, second sub-pixel
It is adjacent with the third sub-pixel of six different colours, the third sub-pixel of different colours divide the top of the second sub-pixel of column, lower section,
Upper left side, lower left, upper right side, lower right.
Further, the computer program is also executed the following steps when being run, and judges whether the first pixel is located at
Face plate edge；When being judged as YES, step is just carried out, centered on the first sub-pixel on panel, establishes sampling mask block.
