ACTIVE TYPE GLASSES WITH REMOVABLE GLASSES WITH BATTERY {3D ACTIVE TYPE GLASSES WITH THE REMOVABLE TEMPLES HAVING A BATTERY}

The present invention relates to three-dimensional glasses, and more particularly, to an active type three-dimensional glasses to which a detachable glasses legs with a built-in battery is applied.

The three-dimensional depth and the sense of space, not the two-dimensional plane, are the biggest features for representing 3D stereoscopic images. Three-dimensional glasses means that the three-dimensional image is viewed by the naked eye by making it look three-dimensional by using parallax of both eyes with chromatic aberration, filter, and the like. In other words, the chromatic aberration and the filter on both sides of the glasses are separated differently so as to feel a three-dimensional effect when viewing various images such as a screen.

The images on the screen wearing stereoscopic glasses seduce audiences by presenting a vivid 3D stereoscopic image that is likely to come out toward the audience and reach out when reaching out. The principle of stereoscopic glasses comes from the human sense of three-dimensionality. Humans have two eyes, and these eyes are arranged at about 65mm intervals, so when looking at an object, the left and right images are wide-angled and imaged on the retina. Factors that make three-dimensional senses include object position, parallax of both eyes, congestion angle of both eyes, and motion parallax of one eye.

The method of wearing stereoscopic glasses uses such a wide angle, and the current technology uses a method using parallax. In the case of the polarization method, it uses the polarization property of the light, and when the left eye image and the right eye image are taken separately and played simultaneously, and when different polarizers are inserted into the left and right images, the light vibrates only in the polarization direction of the polarizer. This is reflected on the screen, which is invisible when wearing polarized glasses at right angles to it, but seen in polarized glasses in the same direction as the polarizer of the projector. In other words, only the left eye image is continuously viewed with the left eye. This image is the way the human brain combines two images and feels as one stereoscopic image.

The shutter glass method divides the parallax and receives the infrared synchronization signal from the projector to form the shutters of both left and right eyes accurately. In other words, the eyeglasses rapidly change the image of the left eye and the image of the right eye, and the human is recognized as being superimposed by the afterimage of the image. The superimposed images are interpreted by the human brain in three dimensions by synthesizing the images, and a method of creating a 3D stereoscopic image using such parallax is a shutter glass method.

In order to use 3D glasses, polarized 3D glasses are sold independently because they do not require a connection with the 3D display, and the domestic market has been secured to some extent. However, due to the lack of contents related to polarized 3D glasses, the utilization is stagnant.

Shutter glass type 3D glasses are often sold together with other 3D display products, rather than being sold independently because they require a 3D display to be connected with a 3D display.

In the case of the shutter glass method, the width of the leg portion should be made wide because the printed circuit board (PCB), the flexible electronic circuit, and the battery device are included in the glasses.

Another problem of the shutter glasses type stereoscopic glasses is that the rechargeable battery is mounted inside the stereoscopic image glasses to charge through a wired cable, so that stereoscopic images cannot be viewed during charging.
