Image processing method, device thereof, and display device

Abstract

The invention provides an image processing method, a device thereof, and a display device, and relates to the display technology field. By adopting the image processing method, the problems of the edges of the images such as jags and color cast can be improved. The image processing method is characterized in that a frame of first image data can be acquired, and a row of real pixels on an edge side of a first image is provided with corresponding virtual pixels, and every virtual pixel comprises the sub-pixel of the corresponding real pixel and at least one sub-pixel adjacent to the corresponding real pixel; the first image data can be converted into the second image data, and by aiming at the at least one row of real pixels on the edge side of the first image, the gray-scale value of every sub-pixel of each of the real pixels can be allocated to the sub-pixel of the corresponding virtual pixel, the color of which is the same as that of the sub-pixel of the above mentioned real pixel, and the gray-scale value of every other real pixel allocated to every sub-pixel is remained; and the sum total of the gray-scale values allocated to the same sub-pixel can be used as the gray-scale value of the sub-pixel of the second image data. The image processing method is suitable for the display of the display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an image processing method and its device, and a display device. Background technique [0002] AMOLED (ActiveMatrixOrganicLightEmittingDiode, Active Matrix Organic Light Emitting Diode) display devices occupy an important position in the field of display technology. [0003] refer to figure 1 As shown, the AMOLED display device includes a plurality of pixels 1 arranged in an array, and each pixel 1 includes: red sub-pixels R, green sub-pixels G and blue sub-pixels B arranged in a magenta shape. The sub-pixels in each pixel can display different brightness, and each pixel can display different gray levels after mixing. The above-mentioned display device arranged in a character shape has good mixing effect and uniform display picture, and is widely used in AMOLED display devices. but refer to figure 1 As shown, in a column of sub-pixels 100 located on the outermost sid...

Problems solved by technology

but refer to figure 1 As shown, in a column of sub-pixels 100 located on the outermost side of the edge, each sub-pixel belongs to a different pixel. In this way, when a non-solid color picture is displayed, there is a difference in the gray scale of adjacent sub-pixels, and at the same time, due to the blue sub-pixel The brightness is smaller than that of the red sub-pixel and the green sub-pixel, which further exacerbates the difference in brig
