View angle enhancement type directional backlight automatic stereoscopic display device

The invention belongs to the field of automatic stereoscopic display, and particularly discloses a view angle enhancement type directional backlight automatic stereoscopic display device which comprises a directional backlight module, a lens array module, a scattering/transmitting controllable module, a liquid crystal display panel and a central control module. The lens array module, the scattering/transmitting controllable module and the liquid crystal display panel are positioned in a light path of the directional backlight module; the central control module is connected with the directional backlight module, the lens array module, the scattering/transmitting controllable module and the liquid crystal display panel. The view angle enhancement type directional backlight automatic stereoscopic display device has the advantages that 2D (two-dimensional) and 3D (three-dimensional) display modes can be freely switched over according to requirements of viewers, and problems of discontinuity, unevenness and the like of visual areas when 2D images are played by directional backlight 3D displays can be solved; view angles can be expanded in the 2D display modes and can reach or can be close to view angles displayed by current 2D panels.
