Three-dimensional display control method and 3D display control device

A 3D display control method, comprising:

• sequentially acquiring left-eye image data or right-eye image data corresponding to each column of subpixels on a display panel for displaying a current frame image;
• and
• sequentially updating images displayed by each column of subpixels according to the left-eye image data or the right-eye image data for displaying the current frame image, and meanwhile updating light shielding regions and light transmitting regions of a grating device corresponding to a previous frame image, so as to achieve a naked-eye 3D image displaying;
• wherein the sequentially updating images displayed by each column of subpixels according to the left-eye image data or the right-eye image data for displaying the current frame image, and meanwhile updating light shielding regions and light transmitting regions of a grating device corresponding to a previous frame image comprises:
• shading all the light transmitting regions of the grating device corresponding to any one column of subpixels, when the any one column of subpixels are being updated to display the current frame image;
• and
• after the any one column of subpixels are completely updated, if a region of the grating device corresponding to the any one column of subpixels also corresponds to a next adjacent column of subpixels adjacent to the any one column of subpixels, when the next adjacent column of subpixels are not completely updated, still shading a light transmitting region of the grating device corresponding to both the any one column of subpixels and the next adjacent column of subpixels, and when the next adjacent column of subpixels are completely updated, immediately converting a state of the region of the grating device corresponding to both the any one column of subpixels and the next adjacent column of subpixels between a light shielding state and a light transmitting state;
• if the region of the grating device corresponding to the any one column of subpixels does not correspond to other columns of subpixels, when the any one column of subpixels are completely updated, immediately converting the state of the region of the grating device corresponding to the any one column of subpixels between the light shielding state and the light transmitting state.
