Abstract
A 3D display device having a lens-switching function. The device includes an LCD picture layer, a lens-array plate, an LCD shielding pattern layer, and a synchronous picture providing system. The synchronous picture providing system is connected with the LCD picture layer and the LCD shielding pattern layer such that the LCD picture layer and the LCD shielding pattern layer are synchronous to respectively display a 3D picture and a shielded pattern. Through increasing an area of black shielding pattern, an edge of each lens unit corresponding to the shielding region is shielded, the area of a single light transparent region is reduced, and a light transparent aperture of a lens unit corresponding to the shielding region is reduced in order to eliminate a cross talk generated by scattering and bluntness at the edge.
