  • the present invention relates to a method of displaying an operating state of glasses for stereoscopic images using an LCD lens and an apparatus therefor.
  • the three-dimensional depth and the sense of space, not the two-dimensional plane, are the biggest features of expressing stereoscopic images.
  • the glasses for stereoscopic images are directly viewed by the naked eye by making the three-dimensional image appear three-dimensionally by using chromatic aberration, filters, and the like, using the parallax of both eyes.
  • 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 image on the screen which is worn with glasses for stereoscopic images, attracts the audience by presenting a vivid stereoscopic image that is likely to come out toward the audience and reach out when reaching out.
  • the principle of glasses for stereoscopic images comes from the human sense of three-dimensionality. Humans have two eyes, and these eyes are placed at intervals of about 65mm, so when looking at an object, the left and right images are formed on the retina with wide angles, and the brain interprets the wide angles to feel a three-dimensional image. 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 the glasses for stereoscopic images uses such a wide angle, and the current technology uses the method using parallax.
  • the polarization method 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 IR synchronization signal from the projector to accurately alternate the left and right shutters.
  • 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.
  • the polarized 3D stereoscopic glasses are sold independently because they do not need to be connected to the 3D display.
  • the utilization is stagnant.
  • Shutter glass type 3D glasses for 3D images must be connected with 3D displays and software is required to connect with 3D displays, so they are often sold with other 3D display products rather than sold independently.
