A 3D conversion lens and a control method therefor. The 3D conversion lens comprises: a first substrate (1) and a second substrate (2), wherein the first substrate (1) and the second substrate (2) form a box; an electronic ink, wherein the electronic ink is filled into a box cavity of the box, and the electronic ink comprises non-transparent charged particles, the non-transparent charged particles containing a non-transparent pigment; an electrode (5) formed on the first substrate (1); and electrodes (6, 7) formed on at least one side wall of the box cavity. The traditional liquid crystal layer is replaced by the electronic ink, so that the 3D display effect of the glasses is achieved by controlling the positive and negative polarities of the transparent electrodes on the substrate and the side wall of the box cavity. Compared with the prior art, no deflection of liquid crystals needs to be controlled and realised, so that a circuit structure can be simplified and a preparation process of the 3D glasses can be simplified. |
