Embodiment Construction

[0013] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0014] The 2.4G wireless module (2.4Ghz RF transceiver / receiver module) works in the range of 2400M-2483M free of application for ISM channels in the world, and realizes the automatic frequency sweep function at startup. There are a total of 50 working channels, which can be used by 50 users at the same time to work at the same time , No need for users to manually coordinate and configure channels. At the same time, based on cost considerations, multiple types of wireless modules within 50 meters, 150 meters, and 600 meters can be selected. The receiving unit and the remote control unit have...

Abstract

The invention provides a 3D signal sending device, which comprises a 3D television and a 2.4G radio-frequency transmitting module, wherein the 3D television is connected to the 2.4G radio-frequency transmitting module through a data line; the 2.4G radio-frequency transmitting module receives a 3D synchronizing signal transmitted from the 3D television, switches the 3D synchronizing signal into a radio-frequency synchronous packet and transmits the radio-frequency synchronous packet. The invention also provides a pair of 3D glasses and a 3D signal transmission system. According to the 3D signalsending device, the pair of 3D glasses and the 3D signal transmission system, which are provided by the embodiments of the invention, through adoption of 2.4G radio-frequency transmission and reception, a user cannot be affected by an angle when the user receives the 3D signal, and a receiving distance is far.

Description

Technical field [0001] The invention relates to a 3D signal transmission device, 3D glasses and a 3D signal transmission system. Background technique [0002] 3D TVs in the prior art usually transmit 3D signals through infrared transmitters, while 3D glasses receive 3D program signals through infrared light. However, infrared transmitters are suitable for short-distance transmission and reception, and require higher angles during reception. This tends to cause the user to be excessively restricted by distance and angle when using it. Summary of the invention [0003] The purpose of the present invention is to provide a 3D signal sending device, 3D glasses and a 3D signal transmission system, so that the 3D program signal can be transmitted farther, and the reception is not affected by the angle. [0004] The present invention provides a 3D signal sending device, including a 3D TV and a 2.4G radio frequency transmitting module. The 3D TV and the 2.4G radio frequency transmitting mod...
