Problems solved by technology

In detail, taking this embodiment as an example, the light source 21 sequentially generates the first-view image, the second-view image, the third-view image, and the fourth-view image on the viewing area adjacent to the panel 27. The stereoscopic image display device needs to be equipped with a rotating polygonal mirror 25, and the rotation method of the polygonal mirror 25 is mostly mechanically operated, which is prone to generate a lot of noise due to friction
And if desire to increase the viewing angle of division, at this moment, then need to correspondingly increase the rotating speed of rotating polygonal mirror 25, make aforementioned shortcoming will be more remarkable
[0007] In fact, if the three-dimensional display effect is achieved by using the spatial multiplex mode (spatial multiplex) or the time domain inter-multiplex mode (time multiplex) alone, there are shortcomings and problems that have yet to be overcome.

Abstract

The invention discloses a projecting device capable of providing images of multiple perspectives. The projecting device comprises a light source module, a polarizing and light splitting element, a first reflective-type light valve, a second reflective-type light valve and a light integrating element, a light incoming face of the polarizing and light splitting element is optically coupled with the light source module, a first light outgoing face and a second light outgoing face of the polarizing and light splitting element are optically coupled to the first reflective-type light valve and the second reflective-type light valve respectively, the light integrating element is optically coupled with the first reflective-type light valve and the second reflective-type light valve respectively, and the light source module sequentially provides first light and second light advancing along different light paths, and can transmit the first light and the second light to a viewer through the polarizing and light splitting element, the first reflective-type light valve, the second reflective-type light valve and the light integrating element to enable the viewer to see the images of at least four perspectives. By the projecting device, the images with multiple perspectives can be provided to a user.

Description

technical field [0001] The present invention is a projection device, in particular, a projection device that can provide images from multiple viewing angles. Background technique [0002] In recent years, in order to pursue realistic and close-to-real images, display technologies have been continuously updated to better meet the needs of users. Therefore, from the pursuit of resolution and color in the early stage of flat display, it has gradually evolved to three-dimensional display devices in recent years to further provide users with three-dimensional experience in addition to high-color flat images. [0003] The main working principle of stereoscopic display is to feed the images of objects viewed from different angles to the left and right eyes respectively. According to the visual characteristics of human eyes, when the two eyes watch two images with the same image content but with parallax, The user will feel that the viewed object has a sense of layering and depth, ...
