Embodiment Construction

[0030] A number of embodiments of the present invention will be disclosed in the following figures. For the sake of clarity, many practical details will be described together in the following description. It should be understood, however, that these practical details should not be used to limit the invention. That is, in some embodiments of the present invention, these practical details are unnecessary. In addition, for the sake of simplifying the drawings, some existing conventional structures and elements will be shown in a simple and schematic manner in the drawings.

[0031] The present invention provides a multi-view display device, which tilts the incident light corresponding to the image of the scanning light source and tilts the lens group, and the angle magnification screen produced accordingly can combine the technical advantages of spatial multiplexing and time multiplexing to expand the field of view .

Abstract

The invention discloses a multi-view display device, which at least includes a projector, a first lens group and a second lens group. The projector has a built-in scanning light source image, the projector tilts an incident light corresponding to the scanning light source image at a first angle, and the first lens group receives and refracts the tilted incident light. The second lens group is inclined at the first angle, receives the incident light refracted by the first lens group, and refracts it, so as to expand a viewing area of ​​the multi-view display device.

Description

technical field [0001] The invention relates to a multi-view display device. Background technique [0002] As far as the prior art is concerned, the traditional naked-view 3D display is a time-multiplexed multi-view display device. The time-multiplexed multi-view display device sequentially projects multiple images to different angles of sight, and the viewer's right eye and left eye can respectively receive the images through different parallax. Disadvantages of the time-multiplexed multi-view display device include: a spatial modulator with a high frame rate is required, and the system light concentration will limit the viewing area. Contents of the invention [0003] The present invention provides a display device using a multi-view angle, tilting the incident light corresponding to the image of the scanning light source and tilting the lens group to obtain the effect of spatial multiplexing, and lowering the resolution in exchange for a larger field of view, which can...
