NAKED-EYE 3D BACKLIGHT MODULE, NAKED-EYE 3D DISPLAY DEVICE, AND NAKED-EYE 3D DISPLAY METHOD

摘要

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 backlight module 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.

1. A naked-eye 3D backlight module, comprising:
a light emitting diode (LED) sequential circuit board comprising a plurality of sets of LED backlight sources, wherein each of the sets of the LED backlight sources comprises n LED units, whereinn is an even integer greater than or equal to 4; a plurality of convex lenses provided in one-to-one correspondence with the LED units, wherein each of the convex lenses is configured to converge a light beam emitted from a corresponding LED unit of the LED units into a parallel light beam, and the parallel light beams converged by all the convex lenses are oriented in a same direction; a plurality of polygonal prisms provided in one-to-one correspondence with the sets of the LED backlight sources, wherein each of the plurality of polygonal prisms has n refracting sides and is configured to refract the parallel light beams oriented in the same direction after passing through the convex lenses into n parallel light beams respectively oriented in n directions; 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 respectively oriented in the n directions after passing through each of the polygonal prisms; 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.
