Embodiment Construction

[0023] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0024] A curved naked-eye 3D display device, comprising a backlight module 210, along the propagation direction of the light emitted by the backlight module 210, a lens array 220, a one-dimensional optical diffusion film 230, and a transmissive image display unit 240 are sequentially arranged, and the transmissive image The display unit 240 is used to load and refresh the parallax stereoscopic image. The light emitted by the backlight module 210 sequentially passes through the lens array 220, the one-dimensional optical diffusion film 230 and the transmissive image display unit 240 to form a viewing area. The lens array 220, the one-dimensional The optical diffusion ...

Abstract

The present invention provides a curved surface naked eye 3D display device, and relates to the field of optical technology devices. The device comprises a backlight module group (210), and a lens array (220), a one-dimensional optical diffusion barrier (230) and a transmission-type image display unit (240) which are arranged in order in a propagation direction of light emitted by the backlight module group (210). The transmission-type image display unit (240) is configured to load and refresh a new parallax three-dimensional image, and the light emitted by the backlight module group (210) passes through the lens array (220), the one-dimensional optical diffusion barrier (230) and the transmission-type image display unit (240) in order to form a watching visual area. The curved surface naked eye 3D display device is ingenious in structure, and can improve the technical defect that a current stereoscopic display device is fixed in a transverse watching freedom degree.

Description

technical field [0001] The invention relates to the field of optical technology equipment, in particular to a curved naked-eye 3D display device. Background technique [0002] 3D display (also known as stereoscopic display) is one of the future development directions of display technology, which provides stereoscopic information images for both eyes through the method of spatially multiplexing parallax images. Correspondingly, the left eye receives the left eye image in the left viewing area, and the right eye receives the right eye image in the right eye viewing area. If the image for the left eye and the image for the right eye constitute a pair of parallax stereoscopic images, the brain can fuse the two to form a 3D image, so that the viewer can feel the corresponding depth information. [0003] At present, mainstream glasses-free 3D display technologies mainly include microcylindrical lens arrays, parallax barriers, and directional backlight technologies. Among them, t...
