Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below with reference to attached in the embodiment of the present invention
Figure, by specific embodiment, is fully described by technical solution of the present invention.Obviously, described embodiment is of the invention
A part of the embodiment, instead of all the embodiments, based on the embodiment of the present invention, those of ordinary skill in the art are not doing
The every other embodiment obtained under the premise of creative work out, falls within the scope of protection of the present invention.
Fig. 1 a is a kind of flow diagram of method for eliminating display figure coloured silk side provided in an embodiment of the present invention.Such as Fig. 1 a
Show, the method for eliminating display figure coloured silk side can specifically include:
Step 110 obtains multiple edge pixels corresponding with display graphic edge in display screen.
Optionally, the dot structure arrangement mode in the display screen can arrange for diamond array or Pentile.Its
In, as shown in Figure 1 b, multiple sub-pixels 110 are arranged in arrays for pentile arrangement, along 110 matrix line direction X of sub-pixel, first
Sub-pixel 111, the second sub-pixel 112 and third sub-pixel 113 circuit sequentially arrangement, wherein first the 111, second son of sub-pixel
Pixel 112 and the color of third sub-pixel 113 respectively red, green and blue are any.The sub-pixel matrix includes first
11 liang of sub-pixel column of sub-pixel column 10 and the second sub-pixel column, the first sub-pixel column 10 and the second sub-pixel column 11 are in row matrix
It is arranged alternately on the X of direction.In the first sub-pixel column 10, the first sub-pixel 111 and third sub-pixel 113 are arranged alternately；?
It only include the second sub-pixel 112 in two sub-pixel columns 11.Along picture element matrix column direction Y, the first sub-pixel 111, the second sub-pixel
112 and third sub-pixel 113 length it is identical；First sub-pixel along picture element matrix line direction X, the first sub-pixel column 10
111 and 113 length of third sub-pixel be greater than the second sub-pixel column 11 in 112 length of the second sub-pixel.In this arrangement mode,
The first sub-pixel 111, the second sub-pixel 112 positioned at picture element matrix edge is different with the size of third sub-pixel 113, therefore meeting
There is color side phenomenon.It is understood that in traditional standard pixel arrangement mode, three in the pixel at pixel array edge
The size of the sub-pixel of kind color type is identical, they can obtain white light with colour mixture, and the probability for color side phenomenon occur is relatively low,
Therefore, the method on display figure coloured silk side is eliminated in the present embodiment in the pixel array for being similar to diamond array or pentile arrangement
Middle better effect.But it should be recognized that although the probability that color side phenomenon occurs in traditional standard pixel arrangement mode is lower,
The risk for color side phenomenon occur is still remained, the method for therefore, in the present embodiment eliminating display figure coloured silk side can be used for passing
The standard pixel arrangement mode of system.
It should be noted that display figure is only the figure shown in screen display picture, image is not entirely shown.Example
Such as, one annulus of screen display is shown, the color of annulus is red, and background colour is white, then show that figure is red annulus, and
It does not include white background.
It should also be noted that, the corresponding edge pixel of display graphic edge is for showing display graphic edge information
Pixel.It is still illustrated by taking above-mentioned red annulus as an example, the pixel for being displayed in red annular edge information is display figure
The corresponding edge pixel in shape edge, i.e., for showing the periphery of the red annulus and the pixel of inner circumferential.It is understood that red
Annulus includes two edges, the two edges are concentric circles, and the corresponding edge pixel of display graphic edge includes display two same
The all pixels of heart circle information.It obtains in display screen after multiple edge pixels corresponding with display graphic edge, it can be by all pictures
The position of element is recorded to carry out subsequent step.

The corresponding edge pixel in shape edge, then B pixel 101 and C pixel 102 are respectively the first picture being disposed adjacent of going together with A pixel 100
Element and the second pixel or B pixel 101 are the second pixel, and C pixel 102 is the first pixel；D pixel 103 and E pixel 104 are distinguished
It is the 4th pixel for the third pixel and fourth pixel adjacent with A pixel same column or D pixel 103, E pixel 104 is third picture
Element.
Illustratively, the multiple edge pixel, first pixel, second pixel, the third pixel and
4th pixel can include that the first sub-pixel, the second sub-pixel and third sub-pixel state the first sub-pixel, described
Two sub-pixels and the third sub-pixel respectively red, green and blue are any.Red, green and blue are light
Three primary colors set one of above-mentioned three kinds for three sub-pixels in a pixel respectively and enable to pixel that can show
The light of various colors enriches the display color of display device.
Step 130, using first pixel, second pixel, the third pixel and the 4th pixel pair
The corresponding edge pixel compensates algorithm process, obtains grayscale value after each edge pixel processing.
Illustratively, each pixel can be made of three different sub-pixels of color type, according to first pixel,
Second pixel, third pixel and the 4th pixel respectively carry out the grayscale value of three sub-pixels in the corresponding edge pixel
Backoff algorithm obtains the grayscale value of above three sub-pixel, and as grayscale value after the corresponding edge pixel processing.
The present embodiment compensates algorithm to corresponding edge pixel using four pixels, compared with the existing technology in be used only two pictures
The mode of element, so that the effect on the color side of grayscale value elimination is more preferable after the processing obtained, treated, and display graphic edge transition is obtained
It is more soft.
The grayscale value of the multiple edge pixel is adjusted to grayscale value after the corresponding processing by step 140.
Specifically, grayscale value after the processing is added in corresponding driving signal, and driving signal is transmitted to aobvious
In display screen in corresponding edge pixel, so that each edge pixel shows the grayscale value in the driving signal received in display screen.
Optionally, the multiple edge pixel, first pixel, second pixel, the third pixel and institute
Stating the 4th pixel includes at least three sub-pixels；At least three sub-pixel has different colors.
