Stereoscopic display device

Abstract

The invention discloses a stereoscopic display device. According to the stereoscopic display device, when an electric field providing device provides an electric field for a first conducting layer and a second conducting layer, the first polarization image signal light passes through a second polaroid and a light transmitting gap. Therefore, an image seen by the left eye and an image seen by the right eye are identical and a two-dimensional plane display image and the purpose that a viewer can view and admire the two-dimensional plane image is achieved. When the electric field providing device does not provide the electric field for the first conducting layer and the second conducting layer, the second polarization image signal light does not pass through the second polaroid, the second polarization image signal light passes through the light transmitting gap, and therefore the left eye sees a left image and the right eye sees a right image. The left image and the right image are different. After the left image and the right image are combined by the brain, stereoscopic perception is generated, a three-dimensional display image is obtained, and therefore the purpose that the viewer can view and admire the three-dimensional image through the naked eyes is achieved. Therefore, the display device can display not only the two-dimensional plane image but also the three-dimensional display image which can be seen by the naked eyes.

Description

technical field [0001] The invention relates to the technical field of stereoscopic display, in particular to a stereoscopic display device. Background technique [0002] With the development of display technology, people can no longer be satisfied with two-dimensional (Two Dimensions, 2D) display images, but need three-dimensional (Three Dimensions, 3D) stereoscopic display devices to provide a more comprehensive and deep information. The basic principles of 3D stereoscopic imaging, including: [0003] There is a certain distance between the left eye and the right eye, so the observation angles of the two eyes are slightly different when watching the scene. The difference in the observation angle makes the left eye see the left image, and the right eye sees the right image, and the left image and the right image are different. Similarly, after being synthesized by the brain, a three-dimensional feeling will be produced to achieve the purpose of viewing three-dimensional s...

Problems solved by technology

[0008] Existing solutions for viewing 3D stereoscopic images require the viewer to wear a special viewing tool such as polarized glasses, shutter glasses, or helmet-type glasses, which cannot achieve the purpose of viewing 3D stereoscopic images with naked eyes.
