Embodiment Construction

[0026] The present invention is implemented like this:

[0027] exist Figure 1 to Figure 6 Among them, an infrared active shutter 3D glasses system is composed of an infrared synchronous signal encoding transmitter and 3D glasses. The functional block diagram of the infrared synchronous signal encoding transmitter is as follows: figure 1 shown. The infrared synchronous signal encoding transmitter is composed of a photoelectric coupling input circuit, an MCU microprocessor and an infrared transmitting circuit. The photoelectric coupling input circuit converts the synchronous signal output by the input stereo TV or other stereo playback equipment into a corresponding voltage signal through the photocoupler, and inputs it to the detection terminal of the MCU. The advantage of this is that the external equipment and the infrared synchronous signal code transmitter are completely isolated on the circuit, avoiding static high-voltage interference and other electromagnetic interf...

Abstract

The invention relates to the field of application of computer peripherals, stereoscopic televisions and other 3D (three-dimensional) devices, in particular to an infrared active-shutter type 3D spectacle system consisting of an infrared synchronous signal coding and transmitting unit and a pair of 3D spectacles. The infrared active-shutter type 3D spectacle system of the invention has the following beneficial effects that: 1) the 3D spectacle system solves the problem of the mutual disturbance between the infrared 3D spectacles and the remote controller of the television; 2) the 3D spectacle system solves the problem that the identical 3D devices can be utilized within the same environment without being disturbed; 3) the 3D spectacle system can achieve the real-time update of device codes; and 4) the 3D spectacle system can keep stable and synchronized with the 3D television after the transient loss of the infrared synchronous signals between the 3D television and the 3D spectacles, and improve the operating stability of the 3D spectacles.

Description

technical field [0001] The present invention relates to the field of application of 3D equipment such as computer peripherals and stereoscopic televisions, and in particular to an infrared active shutter 3D glasses system. It is a 3D glasses system that transmits to the shutter glasses worn by the viewer, so that the switch of the left and right lenses is synchronized with the frame sequence stereoscopic images of the display screen, so that people can produce stereoscopic visual effects. Background technique [0002] With the continuous development of digital video technology, three-dimensional movies and three-dimensional TV will gradually enter the market. Especially with the improvement of the response speed of liquid crystal materials, the current liquid crystal display can achieve a refresh rate of 120Hz or even higher, so that the original frame-sequential time-division stereoscopic image will completely solve the flickering feeling caused by the switching of the left...
