3D TOUCH LIQUID CRYSTAL LENS GRATING, MANUFACTURING METHOD THEREOF, AND 3D TOUCH DISPLAY DEVICE

摘要

Provided are a 3D touch liquid crystal lens grating (11), a manufacturing method thereof, and a 3D touch display device (1). The 3D touch liquid crystal lens grating (11) comprises: a lower substrate (12), comprising a lower transparent substrate (121) and a surface electrode (122), the surface electrode (122) being formed on the lower transparent substrate (121); an upper substrate (13), in cell alignment with the lower substrate (12), and comprising an upper transparent substrate (131) and a strip-shaped electrode (132), the strip-shaped electrode (132) being formed on the upper transparent substrate (131); and liquid crystal, filled between the surface electrode (122) and the strip-shaped electrode (132). At least one touch electrode (133) is adjacently arranged between the upper transparent substrate (131) and the strip-shaped electrode (132), and a transparent isolation cushion layer (134) is arranged between the touch electrode (133) and the strip-shaped electrode (132). The 3D touch liquid crystal lens grating (11) can reduce the double-layer electrode used for touch control in the prior art to a single-layer electrode, thereby reducing the thickness of the 3D touch display device (1), simplifying the manufacturing process, and reducing the production cost of a product.
