Abstract: 3D liquid crystal shutter glasses include a pair of LCD lenses (1), and a control circuit (100) associated with the LCD lenses. The LCD lens includes an LCD-glass layer (2), a front polarizing filter (3), and a transparent scratchproof layer (4) laminated together. The control circuit includes a sync signal receiver (5), an LCD driver (6) for controlling LCD lenses, a boost circuitry (7) associated with LCD driver for outputting a drive voltage to the LCD driver, a CPU (8) which is respectively associated with the receiver, LCD driver, and boost circuitry for controlling operation of the same, and a power supply module (11) for powering the control circuit. The lenses prevent light in environment affecting and flaring thereon. The light transmittance of the lenses is approximated to 40%. Accordingly, the 3D glasses present the user brighter and lively image in higher quality, and avoid hurting user's eyesight.

Abstract: 3D liquid crystal shutter glasses in the present invention include LCD lenses (1) and a control circuit (20, 30) which is operable to receive sync RF signal and drive the LCD lenses operation. The control circuit includes: an RF receiver for receiving sync signal (2); an LCD driver (3) for driving the LCD lenses operation; a boost circuitry (4) for supplying an operating voltage to the LCD driver; a CPU (5) for controlling the RF receiver, LCD driver and boost circuitry; a power control module (7); and a battery (6) for powering the control circuit via the power control module. The glasses can eliminate the impact from light in environment and the orientation limited, and improve the viewing effect and quality of 3D image or video. Therefore, it is more practical.
