1. A three-dimensional display device, comprising:

  • a micro LED (Light-Emitting Diode) display panel, a light control component arranged at a light-emitting side of the micro LED display panel, and a control component electrically connected with the micro LED display panel and the light control component respectively, wherein;

    the control component is configured to control the micro LED display panel to display, and to control the light control component to generate a parallax barrier matching with the micro LED display panel, in a three-dimensional display mode, wherein the parallax barrier comprises light-shielding strips, and light-transmitting strips, which are arranged alternately;

    wherein the control component is configured to control the micro LED display panel to display in a landscape mode or in a portrait mode, according to a detected relative positional relationship of a viewer to the micro LED display panel, and to control the light control component to generate a parallax barrier matching with the landscape mode or the portrait mode, in the three-dimensional display mode;

    wherein the light control component comprises;

    a first substrate and a second substrate arranged opposite to each other, an electrode structure arranged between the first substrate and the second substrate, and a light adjusting layer configured to generate the parallax barrier according to voltage variation of the electrode structure;

    wherein the electrode structure comprises;

    a plurality of transverse strip-shaped electrodes, and a plurality of longitudinal strip-shaped electrodes, which are arranged on a side of the first substrate facing the second substrate, and which intersect in different planes with, and are insulated from each other, and a planar electrode arranged on a side of the second substrate facing the first substrate;

    wherein a width of each of the light-shielding strips and a width of each of the light-transmitting strips in the parallax barrier are equal to a size Wp of a pixel, and a relationship between a distance D between the micro LED display panel and the parallax barrier generated by the light control component, and the size Wp of the pixel comprises;


    D=Wp*L/(Q+Wp)wherein D is a distance between the micro LED display panel and the parallax barrier generated by the light control component, Wp is a size of the pixel, L is a distance between a position of eyes of the viewer and the micro LED display panel, and Q is a spacing between points of view of the viewer.
