What do you mean by flashing the red light and the green light after the switch on the SHARP 3D TV?
Each lens of the shutter type 3D glasses contains a liquid crystal layer which can be black at a certain voltage (low transmittance). On the contrary, it is similar to ordinary lenses without additional voltage. Because the 3D image of each frame contains two images of different angles of left and right images, only when the left face painting through the left lens (lens not loaded fixed voltage), corresponding to the right screen through the right lens, the audience can see the image 3D.Therefore, a synchronous signal is needed to control the alternation of the left and right lenses and the alternation of left and right frames. Typically, infrared signals are used to transmit this synchronization signal. But because of the disadvantages such as easy to be disturbed by daylight lamp and limited communication range, 3D shutter glasses with Bluetooth and high frequency wireless signal communication have been developed. Under the control of synchronous signals, the voltage alternating between the left and right lenses changes alternately, and then the two images are integrated by the brain to achieve the visual effects of 3D.
Because of the principle of essentially shutter 3D technology is implemented according to the refresh time of the human eye image frequency, so the fast refresh rate to improve picture (to achieve 120Hz) to the left and right image fast refresh the 60Hz people on the image will not produce shake movement, and maintain the same with 2D video frames.It is mainly rely on the LCD glasses to achieve, it is the essence of glasses can control the on / off of the two liquid crystal screen, a liquid crystal layer in the eyes with black and white two, usually displayed as white or transparent state, electricity will become black. By means of a signal transmitter, precise synchronization between the 3D eyes and the screen is achieved. The display screen will be alternately left and right eye screen playback, when playing the left screen, the left glasses open, the right glasses off, the audience left eye to see the need to let the left eye to see the picture, the right eye can not see anything. In the right eye screen is the right eye to see the right picture, the left eye can not see the picture, so that the left and right eyes to see their respective images, so as to achieve the three-dimensional effect of 3D. The process of alternating at least 120 times per second, the human eye can enjoy a coherent but not blinking 3D screen, so the active 3D display technology requires the refresh rate of the screen at least 120Hz.Recommend smart TV & Android set-top box download and install, when the beta application market, rich applications, download speed, can maximize the playability of tv!
You should use a shutter type 3D glasses, the 3D technology will flicker in principle. Shutter 3D eye is to change the power to change the effect of 3D through the lens with liquid crystal glasses. The principle is a bit complicated. I still use Baidu encyclopedia to explain it.3D glasses shutter 3D technology design mainly through improving the picture fast refresh rate (usually 120Hz) to achieve the 3D effect, which belongs to the active 3D technology, also called time-sharing shading technology or LCD time-sharing. When the 3D signal input to the display device (such as a display, projector etc.) after the implementation of about the frame to produce alternating sequence images with frame format, through the infrared transmitter, Bluetooth wireless signal transmission of these frames will go out, is responsible for receiving 3D refresh synchronization eye glasses in the corresponding image and keep watch, and 2D like the same frames, the audience eyes see a different picture of fast switching, and the illusion in the brain (the camera does not come out, they see stereo effect) image.
