2D-3D switching device of naked eye 3D display

摘要

The present invention provides a 2D-3D switching device of a naked eye 3D display, comprising a first substrate (1), a second substrate (2) oppositely located to the first substrate (1), a plurality of electrodes (3) located between the first substrate (1) and the second substrate (2) and on the second substrate (2), a dielectric layer (4) formed on the second substrate (1) and completely covering surfaces of the plurality of electrodes (3) and a first fluid (51) which is hydrophobic and a second fluid (52) which is hydrophilic which fill between the first substrate (1) and the second substrate (2); the first substrate (1) comprises a prism (11), and a side of the first substrate (1) having the prism (11) is opposite to the second substrate (2), and the prism (11) of the first substrate (1) comprises a plurality of curved surface zones (111) which are evenly distributed and a plurality of perimeter zones (112) located surrounding the curved surface zones (111), and each of the electrodes (3) is positioned corresponding to one curved surface zone (111). The device can commodiously achieve the switch between 2D display state and 3D display state of the naked eye 3D display.
