Abstract
The present application provides an image display method and an image display device. The image display method performs a gray-scale compensation on each data line, thereby preventing a problem of color crosstalk in a display panel. At the same time, an original image in the display panel is edge blurred, which can reduce an impact of the color crosstalk.
Claims17
An image display method for reducing crosstalk, which comprises following steps:
- obtaining an original image of a display image displayed on a display panel;
- performing a first filtering process on the original image to obtain a first filtered image;
- performing a difference calculation on the original image and the first filtered image to obtain an edge information image;
- determining filtering parameters of a second filtering process based on a maximum pixel value of the edge information image;
- performing the second filtering process on the original image according to the filtering parameters to obtain an edge blurred image;
- and
- displaying the edge blurred image;
- wherein the first filtering process is a mean filtering process;
- wherein the step of determining the filtering parameters of the second filtering process based on the maximum pixel value of the edge information image comprises:
- forming a filter of five rows and five columns through preprocessing, wherein a pixel value of each position point in the filter represents the filtering parameters, and the filtering parameters comprise a center parameter and edge parameters;
- and
- by following formulas, performing a conversion calculation on the maximum pixel value of the edge information image to obtain values of the center parameter and the edge parameters:
- B=I-P/255;
- A=P/255/24;
- wherein B denotes the center parameter, A denotes each of the edge parameters, and P denotes the maximum pixel value of the edge information image.
