A kind of image display drive method, device and equipment

Technical field

The present invention relates to a kind of image processing field more particularly to image display drive method, device and equipment.

Background technology

Currently, traditional ultra high-definition display technology includes mainly RGB (red, green, blue) ultra high-definition display technologies and RGBW (red, green, blue, white) ultra high-definition display technology.Wherein, RGBW ultra high-definitions display technology be traditional RGB three primary colours (that is, it is red, Green, blue) on the basis of increase white (White) sub-pixel (Sub-pixel), form RGBW structures, i.e. display device Each pixel is by red sub-pixel, green sub-pixels, blue subpixels (that is, three primary color sub-pixels) and white sub-pixels structure At operating voltage or electric current by adjusting for driving different subpixel (are also referred to as so as to adjust the brightness of different subpixel Grayscale value), so that each pixel is showed different colours.

In the prior art, there are RGBW structures a variety of different structures, such as linear arrangement (can also become vertical bar type to arrange Cloth), linear arrangement refers to that each pixel is respectively arranged with three primary color sub-pixels and white sub-pixels in a first direction, with first In the vertical second direction in direction, two adjacent subpixels are to show the sub-pixel of same color.

When two laterally adjacent pixels need to show different colours, need to light difference in adjacent two pixel at this time Pixel lights at most three sub-pixels in the first~four sub-pixel of the first pixel and lights the of the second pixel At most three sub-pixels in one~four sub-pixel, to enable the sub-pixel mixing composition different colours lighted；So And from hardware configuration, first sub-pixel of the first pixel (sub-pixel for being located at the leftmost side) and the second pixel 4th sub-pixel (sub-pixel for being located at the rightmost side) relatively far apart, when only first sub-pixel for emitting light in the first pixel and In second pixel when only the 4th sub-pixel for emitting light, due to being spaced 6 not light emitting sub-pixels between the two, and human eye vision is caused On stain (or black line).

For example, the prior art is illustrated by taking vertical bar type WRBG arrangement as an example, Fig. 1 show in the prior art by Yellow to the black line in the excessive picture of white schematic diagram, referring to Fig.1, when needing to show by yellow to white excessive picture When, due to for showing red sub-pixel in the pixel of yellow color and green sub-pixels and the pixel for showing white colour In white sub-pixels distance (be separated by 5 not light emitting sub-pixels between green sub-pixels and white sub-pixels) farther out, therefore, from From the point of view of in human eye vision effect, it is easy to by continuous 5 not light emitting sub-pixel be mistakenly considered a black line.

As it can be seen that in the prior art, when needing that the pixel of special color is presented, it is likely that within the pixel due to sub-pixel The phenomenon that arranging different, and generating apparent black line.
