Abstract
Disclosed are a naked-eye 3D backlight module, a naked-eye 3D display device, and a naked-eye 3D display method. The naked-eye 3D display device comprises: a light emitting diode (LED) sequential circuit board comprising a plurality of sets of LED backlight sources; a plurality of convex lenses provided in one-to-one correspondence with the LED units; a plurality of polygonal prisms provided in one-to-one correspondence with the LED backlight sources; a thin film transistor liquid crystal display (TFT-LCD) having a refresh frequency the same as a sequential frequency of the LED backlight sources and configured to control transmissions of the n parallel light beams; and a multiple-viewing-angle parallax barrier configured to form the n parallel light beams, which are respectively oriented in the n directions after passing through the TFT-LCD, into an n-viewpoint area display in space. A three-dimensional (3D) viewing angle for the human eyes is greatly enlarged.
