Abstract: A 3D image display system comprising an image display, an image polarizing processor, an image filter, an image synchronizer, and a pair of electronic liquid crystal polarizing spectacles is capable of presenting a 3D image in combination with the conventional low-frequency Field-Sequential Displaying technique. To begin with, by utilizing an optical polarizing process, the possible region where the flickering phenomenon may occur is confined on the screen of the display such that the region may become a small portion of the visual space. Next, an image filter is used to reduce to the intensity of the localized flickering region. Therefore, the flickering phenomenon can be effectively reduced even at a low scanning frequency of 60 Hz.

Abstract: One amendatory structure of 3D LCS glasses, it is further a pair of 3D glasses being designed based on human ergonomic that provides a more light-weighted and comfortable wearing condition, that is, the present invention allows users to enjoy many different types of 3D applications by wearing the present invention for a longer period of time. By means of three individual parts, including a frame, a shelf and an nose-rack, the present invention can be assembled by connecting each part, or disassembled into three separate parts. The frame of the present invention is designed to be rotary and can be flipped up and down, while the nose-rack is designed to be adjusted vertically. The best wearing condition can be achieved by adjusting position of the frame and the nose-rack.

Abstract: A shutter synchronization circuit for a stereoscopic system, which comprises a CPU, a main memory, a VGA graphic card, a monitor, a RS 232 interface circuit, an interrupt controller, a timer and an external shutter synchronizer with RS 232 interface; the circuit is to be used in personal computers; by using the RS 232 interface and the external shutter synchronizer with RS 232 interface, the switching of the LCD shutter and the vertical synchronization scanning signal of the VGA graphic card can be in synchronization. By using a hardware system of a stereoscopic image, a user can see a stereoscopic scene instead of a plane image.

Abstract: A computerized stereoscopic image system and a method of using two-dimensional images with multi-layer for providing a view having a visual depth are disclosed. The stereoscopic image system includes a computer, a main memory unit, a VGA graphic card, a monitor, an external shutter synchronizer, and a LCD shutter eye-glasses. The method of using two-dimensional images with multi-layer for providing a view having visual depth is done by using a binocular shift and sequential displays of stereoscopic images on a monitor in such a manner that, as soon as the user puts on a pair of LCD-shutter eye-glasses, he or she will see a stereoscopic image.

Abstract: It is a pair of glasses capable of producing a 3-D visual effect, mainly including a frame, two polarizing lenses set in the frame, and two additional lanminated lenses removably disposed either in front of or behind the two polarizing lenses. The laminated lenses each consists of two glass sheet layers, an LCD layer between the two glass sheet layers, and a polarizer layer attached to an outer side of one of the two glass sheet layers. When a voltage is applied to the LCD layer, molecules constituting the LCD layer rotate and change their arrangement directions to produce light blocking effect, enabling the glasses to be used as an LCD shutter glass for watching a 3-D image system. When the additional laminated lenses are removed, the glasses can be used as a normal sun glass.
