Description

Video glasses

Technical Field

The utility model relates to the technical field of display, in particular to video glasses.

Background

Human eyes have a 3D effect when seeing objects, because the left eye and the right eye have a distance of 5-6.5 cm in the horizontal direction, certain displacement difference exists between the same point on the picture seen by the left eye and the right eye corresponding to the actual object, and the human brain can sense the distance and the depth of the objects through the difference, namely the parallax principle. According to the parallax principle, when the same scene enters into the eyes, two images with different positions can be formed due to the difference of the visual angles of the eyes, and then the two eyes can respectively see the corresponding images, so that the brain can be stimulated to generate a 3D stereoscopic effect.

The 3D technology is a 3D cinema, and is a relatively common 3D technology in life, wherein two groups of pictures are arranged on a screen during showing by combining left and right pictures with different polarization angles with polarized glasses, and if the 3D glasses are not worn, the seen pictures are blurred and have double images. The working principle of the existing 3D technology is shown in fig. 1, a screen during projection includes a first picture 11 and a second picture 12, and the two pictures are polarized pictures polarized at 90 degrees, after passing through a 3D glasses, the first picture 11 can only pass through a left window 21, the second picture 12 can only pass through a right window 22, so that the left eye can only see the first picture 11 shot by a left camera, and the right eye can only see the second picture shot by a right camera at 90 degrees, thereby simulating parallax when human eyes actually see objects, and making the brain sense the 3D effect.

However, the 3D technology requires a display device capable of providing a polarized image, and a general display device does not have a corresponding function, so that a device capable of realizing a 3D effect according to a general image is urgently needed.
