Description

Stereoscopic display device

The present invention relates to a display device, and more particularly to a stereoscopic display device.

At present, there are mainly two methods for displaying a stereoscopic image by a stereoscopic display device. One is that the viewer must wear the specially treated glasses to view the display device so that the left eye and the right eye receive different images, or the left eye and the right eye. The images alternate to produce a stereoscopic image. This method can be used to see stereoscopic images by the viewer wearing additional glasses, which is inconvenient to use.

The other is a naked-eye display device, which is a principle in which the display device uses a grating, so that the viewer can make the stereoscopic image different from the image seen by the left eye and the right eye without wearing any additional device. Used in print, baseball cards or partially naked-eye electronic stereo displays. A conventional stereoscopic display device includes a display panel and a cylindrical lens array. The display panel includes a plurality of pixels, and the lenticular lens array is disposed opposite to the pixels. Each pixel includes three sub-pixels, wherein the light emitted by the odd pixels passes through the lenticular lens array to form an image seen by the left eye, and the light emitted by the even pixels passes through the lenticular lens array. Form the image seen by the right eye. Thus, conventional stereoscopic displays produce a right eye viewable area as well as a left eye viewable area at a particular distance.

When the viewer's left and right eyes are in the left-eye viewable area and the right-eye viewable area, the viewer can view the stereoscopic image. However, due to the conventional stereoscopic display device The left eye visible area and the right eye visible area have a small range. When the viewer moves slightly to the left or right, the viewer's left and right eyes will respectively fall in the right eye visible area and the left eye visible area, the viewer. The left eye and the right eye both fall in the visible area of the right eye or the left eye and the right eye of the viewer fall in the visible area of the left eye, so that the viewer does not see the stereoscopic image.

The present invention provides a stereoscopic display device to solve the problems of the prior art.

The second light beam is used to form a visible area of the right eye, so that the stereoscopic display device disclosed in the present invention has A wide range of left-eye visible areas and right-eye visible areas, thereby reducing the situation where the viewer does not see the stereoscopic image, solves the problems of the prior art.

Although the present invention has been disclosed above in the foregoing preferred embodiments, it is not intended to be limiting. In the present invention, the scope of the patent protection of the present invention is defined by the scope of the patent application attached to the present specification, without departing from the spirit and scope of the present invention. quasi.
