Abstract

The present invention relates to the technical field of naked-eye 3D display, and provides a flicker-free directional backlight naked-eye 3D display device for multi-person viewing. An image control module converts image data into a 3D image, and a parallax 3D image is output to a first or Nviewer through the cooperation of a display unit, a triangular prism-shaped microstructural directional beam-splitting film, and a directional backlight module, a quantity of viewers is determined by a human eye position signal in a display area collected by a human eye tracking module. The directional backlight module provides motion parallax, and the triangular prism-shaped microstructural directional beam-splitting film provides binocular parallax, so that the resolution is lost by only half in a horizontal direction and remains unchanged in a vertical direction, so that ultra HD 3D images can be implemented for one or more persons.
