Stereoscopic display device and control method thereof

A control method for a stereoscopic display device, wherein the stereoscopic display device comprises:

• a display substrate, comprising a base substrate and a plurality of pixel units provided on the base substrate, wherein the plurality of pixel units are arranged in an array in a first direction and a second direction intersecting with the first direction;
• and a cylindrical lens array located on a light exit side of the display substrate;
• the control method comprising:
• determining a layout period according to a relative positional relationship between a human eye, the cylindrical lens array and the display substrate and according to a refraction of the cylindrical lens array for light emitted by the plurality of pixel units;
• and
• controlling the plurality of pixel units to periodically display a left eye image and a right eye image according to a determined layout period,
• wherein the cylindrical lens array comprises a plurality of cylindrical lenses arranged in the first direction;
• wherein a design point on a cylindrical lens corresponds to a first light exit point and a second light exit point on a light exit surface of the display substrate, light emitted from the first light exit point and incident on the design point enters the human eye after being refracted by the cylindrical lens, and the second light exit point, the design point and the human eye are located on a same straight line;
• and
• wherein the controller is configured to determine the layout period such that a distance between the first light exit point and the second light exit point in the first direction is less than or equal to a specified value, so as to avoid a crosstalk between images displayed by two adjacent layout units, and the layout unit comprises at least one pixel unit configured to display the left eye image or the right eye image, and a plurality of layout units are periodically arranged in the first direction according to the layout period.
