3D (three-dimensional) glasses system and signal processing method thereof

Abstract

The invention provides a 3D (three-dimensional) glasses system and a signal processing method thereof. The 3D glasses system comprises a wireless radio frequency transmission module, a wireless radio frequency receiving module, a liquid crystal driving module, a left liquid crystal lens and a right liquid crystal lens, wherein the wireless radio frequency transmission module is used for converting a synchronizing signal based on frame alternate into a radio frequency data packet and performing the broadcast transmission of the radio frequency data packet; the wireless radio frequency receiving module is used for receiving the radio frequency data packet, generating and outputting a liquid crystal lens control signal; the liquid crystal driving module is used for generating and outputting a driving signal for driving the liquid crystal lenses according to the liquid crystal lens control signal; the left liquid crystal lens and the right liquid crystal lens are alternately opened and closed according to the driving signal; the wireless radio frequency receiving module comprises a period prediction unit and a power control unit, wherein the period prediction unit is used for predicting a period the wireless radio frequency receiving module receives the radio frequency data packet; and the power control unit is used for controlling the power of the wireless radio frequency receiving module according to the predicted period so as to lower power consumption. According to the 3D glasses system and the signal processing method thereof, effective use distance can be increased while the low power consumption of the 3D glasses is ensured, and the 3D glasses system is hardly affected by blocking within an effective use range, and has stronger adaptability and antijamming capability.

Description

technical field [0001] The invention relates to the technical field of image display and wireless transmission, in particular to an active shutter type 3D glasses system with low power consumption based on wireless radio frequency transmission and a signal processing method thereof. Background technique [0002] It has always been the dream of people to experience the 3D video effect of the real world on the screen. With the continuous advancement of technology, engineers have developed a series of 3D display devices with different technology types, and 3D display can be realized by wearing active shutter glasses. The effect is one of the more common ones. [0003] The basic principle of active shutter glasses to achieve 3D effects is that the screen works at twice the original refresh rate, half of the frames display the images that the left eye should see, and the other half of the frames display the images that the right eye should see. The image frames of are displayed ...
