Embodiment
Below in conjunction with accompanying drawing, the embodiment of the driving method of the display panel that the embodiment of the present invention provides and display panel, display device is described in detail.
The arrangement that driving due to display panel overturns mode and pixel is closely bound up, first introduces a kind of display panel that the embodiment of the present invention provides for convenience of description.
Particularly, the display panel that the embodiment of the present invention provides is: be a repeating groups cycle arrangement with the sub-pix comprising all colours in display panel; In repeating groups, the color of two adjacent sub-pixs is different, and there is at least one special-shaped sub-pix and run through two standard sub-pix is capable and it is of a size of two the standard sub-pixs size sum in a column direction adjacent with its row in a column direction.
Sub-pix arrangement in the display panel that the embodiment of the present invention provides adopts special-shaped sub-pix arrangement mode, can be wherein a repeating groups cycle arrangement with the sub-pix comprising all colours, illustrate: if comprise the sub-pix of RGBXY five kinds of colors in display panel, then need the sub-pix comprising whole five kinds of colors in a repeating groups.Certainly, the sub-pix more than five kinds of colors can also be comprised in display panel, do not limit at this.All comprise RGBXY for the color of sub-pix in display panel to be in the following description described.Wherein, R is generally redness, and G is generally green, and B is generally blueness, and X is traditionally arranged to be the luminance compensation look that can regulate panel luminance, and Y is traditionally arranged to be the colour gamut complementary color that can regulate panel colour gamut.Usually, X can be set to white, and Y can be the one in yellow, magenta, cyan, because yellow, brightness is also higher usually, so yellow also can as luminance compensation look X.
Particularly, in the repeating groups of the display panel that the embodiment of the present invention provides, the color of two adjacent sub-pixs is different, the color of adjacent two sub-pixs adjacent with row is all not identical at once, can ensure the relatively uniform arrangement in display panel of the sub-pix of each color when carrying out virtual drive like this.
And the special-shaped sub-pix of the display panel that the embodiment of the present invention provides is embodied in, two kinds of sub-pixs are comprised in repeating groups, one is special-shaped sub-pix, another kind is standard sub-pix, can think that the size in a column direction of special-shaped sub-pix is the size sum of two standard sub-pixs, namely to run through two standard sub-pixs capable for special-shaped sub-pix.
And, in the specific implementation, in the above-mentioned display panel that the embodiment of the present invention provides, can be set to the capable continuous arrangement in a column direction of standard sub-pix that runs through by each special-shaped sub-pix, namely in each column criterion sub-pix is capable, all can there is at least one special-shaped sub-pix, so also can ensureing each special-shaped sub-pix relatively uniform arrangement in display panel when carrying out virtual drive further.
Further, in the above-mentioned display panel that the embodiment of the present invention provides, the standard sub-pix that the described special-shaped sub-pix that the capable needs of standard sub-pix and other that arbitrary special-shaped sub-pix runs through are arranged in different rows runs through is capable not to be overlapped, namely during each standard sub-pix in display panel is capable, exist in there will not be three adjacent column criterion sub-pixs capable simultaneously and run through the special-shaped sub-pix of the first row and the second row and run through the special-shaped sub-pix of the second row and the third line, equally also can ensure each special-shaped sub-pix relatively uniform arrangement in display panel when carrying out virtual drive further.
In the specific implementation, because in display panel, color is that the effect of the sub-pix of X and Y is respectively and compensates colour gamut and compensate for brightness, therefore its size can be set to be that the sub-pix of RGB is different from color, namely, when in the display panel that the embodiment of the present invention provides, the color of sub-pix comprises RGBXY, in repeating groups, the size of color to be sub-pix and the color of X and/or Y the be sub-pix of RGB is different.Namely in repeating groups, color is that the sub-pix of X and/or Y can for special-shaped sub-pix, and accordingly, color is the sub-pix of RGB is standard sub-pix; Or in repeating groups, color is the sub-pix of X and/or Y is standard sub-pix, color is the sub-pix of RGB is special-shaped sub-pix.
Further, for the sub-pix arrangement in the above-mentioned display panel that the embodiment of the present invention provides, a kind of display device is also provided, comprises above-mentioned display panel, this display panel has sub-pix described above arrangement, can realize uniform arrangement and good display effect.This display device can be the various device comprising display panel, as computer, mobile phone, digital camera, ATM, navigating instrument etc.
