Claim:
1. A method for controlling stereoscopic display, comprising: obtaining, by a collection device, a position variation between a space position of a viewer at current time and a space position of the viewer at previous time, wherein the position variation is an offset of parallel translation of the space position of the viewer relative to a display panel; and adjusting, by an adjusting device, a stereoscopic display apparatus based on the space position of the viewer at the current time and the position variation, wherein adjusting the stereoscopic display apparatus based on the space position of the viewer at the current time and the position variation further includes: calculating a total number of compensated electrodes in a slit grating period based on the position variation: calculating a total number of electrodes to be shifted based on the space position of the viewer at the current time and the number of compensated electrodes, wherein the total number of electrodes to be shifted is larger than the total number of compensated electrodes in the slit grating period: and adjusting electrode voltage to move the slit grating by the total number of electrodes to be shifted; wherein: calculating the number of compensated electrodes k in a slit grating period by: wherein Δ represents a position variation; s represents a total number of electrodes within a slit grating period; w represents the width of a viewing zone; and h represents a preset scale factor, calculating the number of electrodes to be shifted N by: wherein x represents a space position of a viewer at the current time; z represents a distance between the position of the viewer at the current time and the slit grating; f represents a distance between the slit grating and a pixel plane of the display panel; u represents the width of an electrode of the slit grating; and k represents a total number of compensated electrodes in a slit grating period.
