Abstract
Transparent display device, manufacturing method and controlling method thereof are provided. The transparent display device includes a light guide plate with a rectangular light exit, and a liquid crystal unit including multiple strip electrodes arranged in parallel and a black matrix; the black matrix includes a first and second strip-shaped light-shielding layers; an arrangement direction of the multiple strip electrodes is not parallel to any edge of the light exit; an orthographic projection of the first strip-shaped light-shielding layer on the light guide plate covers at least a center of the light exit and an extension direction of which is parallel to a first edge of the light exit, and an orthographic projection of the second strip-shaped light-shielding layer on the light guide plate covers at least the center of the light exit and an extension direction of which is parallel to another edge perpendicular to the first edge.
