Abstract

The invention provides a multimode three-dimensional display device. The multimode three-dimensional display device is composed of a 2D display panel, a lens array and a transparent liquid crystal display panel. The 2D display panel is used for providing a mode image, the mode image is composed of a bright spot array, and the pitch and the position of the bright spot array are adjustable. The transparent liquid crystal display panel is used for providing a parallax image without changing the light propagation direction. The lens array is located in the middle and used for projecting images. Aplurality of visual areas are preset in a space, and the visual areas are arranged in the space to form a visual area array. Each visual area corresponds to one mode of the multimode three-dimensionaldisplay device. In each mode, the 2D display panel is provided with a mode image corresponding to the 2D display panel. For time division multiplexing, the 2D display panel provides mode images of all the visual areas in sequence, and the transparent liquid crystal display panel provides parallax images corresponding to all the visual areas in sequence. When two eyes of a viewer are located in different visual areas respectively, the corresponding parallax images can be seen respectively, and therefore three-dimensional vision is generated.

Description

technical field [0001] The present invention relates to display technology, more specifically, the present invention relates to stereoscopic display technology. Background technique [0002] Stereoscopic display technology is a display technology that can realize the true reproduction of stereoscopic scenes, and it can provide different parallax images for human eyes, so that people can have stereoscopic vision. The number of viewpoints and resolution of traditional stereoscopic display devices are limited, and it is difficult to provide highly realistic stereoscopic images. The present invention provides a multi-mode stereoscopic display device, which can provide a large number of viewpoints and high-resolution images, thereby improving the stereoscopic display effect. Contents of the invention [0003] The invention provides a multi-mode stereoscopic display device. attached figure 1 It is a structural schematic diagram of the multi-mode stereoscopic display device. ...
