Problems solved by technology

[0004] However, the above-mentioned stereoscopic technology realized by using two displays has several disadvantages: two liquid crystal displays are required, the volume is large, and the cost is high.
[0005] However, the stereoscopic display realized by the above-mentioned single display has the following disadvantages: the screen flickers seriously, and the liquid crystal shutter glasses are wired and heavy, thus producing a stereoscopic display technology without glasses
However, due to the limitations of existing display technology, this stereoscopic display method without glasses has many disadvantages, such as low resolution, low brightness, can only be viewed by a single person, and the cost is too high, etc.

Embodiment Construction

[0033] The invention will now be described in more detail with reference to the accompanying drawings of exemplary embodiments.

[0034] Figure 4 Denotes: Polarizing grating screen according to an exemplary embodiment of the present invention. refer to Figure 4 , the polarizing grating screen 41 is composed of polarizing elements 41a and 41b, such as Figure 4 As shown, the polarizing element 41a and the polarizing element 41b are placed alternately in the horizontal and vertical directions to form a polarization grating screen 41, and the transmission directions of the polarizing element 41a and the polarizing element 41b are vertical, that is, the polarizing element 41a and the polarizing element 41b are respectively transmitted through The polarized light generated by 41b is perpendicular to each other in the polarization direction.

[0035] The polarizing elements 41a and the polarizing elements 41b are placed alternately in the horizontal and vertical directions to f...

Abstract

A three-dimensional display for viewing two-dimensional image and three-dimensional image is provided, which comprises a common two-dimensional image display device (LCD panel, plasma panel and CRT display are all available), a polarized light grid screen and a polariscope, wherein, the polarized light grid screen in the shape of raster comprises two kinds of polarized elements whose polarization orientations are mutually perpendicular lines, which are the first polarized element and the second polarized element. The two polarized elements are overlapped with each other on both horizontal direction and vertical direction. Each polarized element at least corresponds to one subpixel on the display device, which is one of the red subpixel, green subpixel and blue subpixel.

Description

technical field [0001] The device and method of the present invention relate to a stereoscopic display capable of displaying two-dimensional images and three-dimensional images and a method thereof, in particular, to a stereoscopic display capable of displaying three-dimensional images or two-dimensional images using a polarization grating screen and its method. Background technique [0002] The binocular parallax produced by the two eyes separated by about 60mm is the most important factor to produce the stereoscopic effect. Therefore, using the binocular parallax principle to make the left and right eyes see different images can make people get a very real stereoscopic feeling. Therefore, in the field of stereoscopic display, various stereoscopic display technologies utilizing binocular parallax have emerged, and these stereoscopic display technologies are widely used in various fields such as medicine, education, military affairs, architecture, and games. These stereosco...
