1. A display method applicable to a display device, the display device comprising a liquid crystal light control panel and a liquid crystal display (LCD) panel stacked together,
the method comprising:
acquiring a first sub-image and a second sub-image of an image to be displayed on the LCD panel, a boundary of the first sub-image being in contact with a boundary of the second sub-image, a grayscale value of the first sub-image being greater than a grayscale value of the second sub-image;
determining whether the grayscale value of the second sub-image is greater than a grayscale threshold;
in response to determining that the grayscale value of the second sub-image is greater than the grayscale threshold, adjusting a grayscale value of a first region, which is in contact with a boundary of a second light control region, in a first light control region, such that an adjusted grayscale value of the first region is less than a grayscale value of the first region before adjustment, wherein the first light control region is a region of the liquid crystal light control panel corresponding to the first sub-image, and the second light control region is a region of the liquid crystal light control panel corresponding to the second sub-image;
in response to determining that the grayscale value of the second sub-image is not greater than the grayscale threshold, adjusting a grayscale value of a second region, which is in contact with a boundary of the first light control region, in the second light control region, such that an adjusted grayscale value of the second region is greater than a grayscale value of the second region before adjustment; and
controlling the LCD panel to display the image to be displayed, and controlling the liquid crystal light control panel to display a light control image, wherein a grayscale of the light control image is adjusted.
