Background
3D display technology related to LED display screens has become a new research field and direction; by utilizing the parallax principle, when a viewer watches a picture, only two groups of images with slightly staggered shooting positions are provided for the left eye and the right eye to watch respectively, so that a group of pictures with stereoscopic impression can be seen; the parallax error principle is used as the basis for the fact that the parallax error is not separated from the original image. The two sets of pictures are alternately played in a very short time, specifically, the picture entering the left eye of a viewer is played by the LED display screen during the first refreshing, the right eye of the viewer is shielded by the glasses worn by the viewer, and the left and right directions are switched during the next refreshing; continuously exchanging the two actions, namely switching two sets of shutter pictures at high speed, and finally forming continuous 3D pictures by using the persistence characteristics of human eyes and the synthetic action of brain;
at present, widely used glasses are liquid crystal shutter glasses capable of continuously shielding left and right eyes at a high speed, the method has high synchronization requirements on an LED display screen and the liquid crystal shutter glasses, special wireless transmitting equipment needs to be added to synchronize the LED display screen and the liquid crystal shutter glasses, and the cost is increased, so that an LED video processor with a 3D synchronization function is designed and produced, and the problems are solved.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a LED video processor with 3D synchronization function to solve the problem that proposes among the above-mentioned background art.

Detailed Description
In order to facilitate the use, the embodiment of the utility model provides a LED video processor with 3D synchronization function is provided. The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present embodiment provides an LED video processor with a 3D synchronization function, including aPC 1 and anLED video processor 2, a signal output port of the PC 1 is connected to a signal input port of theLED video processor 2, a signal output port of theLED video processor 2 is connected to an LEDlarge screen 5 and a glasseswireless transmitting device 3, and the glasseswireless transmitting device 3 is connected toshutter glasses 4 through a wireless signal.
The 3D input port of theLED video processor 2 is connected with a display card through a 3.5mm earphone cord;
theshutter glasses 4 comprise a Bluetooth receiving module, and theshutter glasses 4 are provided with a switch for controlling the Bluetooth receiving module to receive the synchronous signal sent by the glasseswireless transmitting equipment 3.
In this embodiment, a video image enters theLED video processor 2 through a DP connection line or an HDMI connection line, scaling processing is performed as required, and then output is performed through an HDMI connection line or a DVI connection line, a 3D synchronization signal is output, the video card accesses the synchronization signal into a 3D input port of theLED video processor 2 through a 3.5mm headphone cable, and output is performed from a 3.5mm output port through synchronization delay processing, after the video signal is transmitted to an interface circuit of theLED video processor 2 through a cable, image information of each frame is written into an input video memory to be processed, and is displayed on the LEDlarge screen 5 after being processed by the transmitting card and the receiving card, and this series of processes causes the video displayed by the LEDlarge screen 5 to be delayed by several frames compared with the video transmitted by the signal source; moreover, according to the number of the intermediate devices and the different processing speeds of the sending card and the receiving card, the video signal on thelarge LED screen 5 has delay of uncertain time; the utility model discloses can change numerous and diverse into the letter, through postponing glasses synchronizing signal, reach the purpose synchronous with video signal, promptly through developing 3D synchronous technology, through carrying out delay operation toshutter glasses 4 signal, reach the purpose synchronous with LEDlarge screen 5, that is to say no matter how many grades of video equipment of LEDlarge screen 5 image process, it is how much to delay through the card of sending, all can be synchronous with liquid crystal shutter glasses signal, operating personnel need not know the synchronization mechanism, only need takeshutter glasses 4, it is long when delaying in 2 menus through adjustment LED video processor, observe LEDlarge screen 5 while adjusting, when the screen 3D effect appears, just it is synchronous withshutter glasses 4's synchronizing signal to show LEDlarge screen 5, what sees and is obtained promptly, and is simple and practical.
The model of theLED video processor 2 is LED-W4000, the model of the glasseswireless transmitting equipment 3 is H19FR, the glasseswireless transmitting equipment 3 is a 3D active type three-dimensional radio frequency signal transmitter, the models are all H19FR, and the model of theshutter glasses 4 is H19C, and the type of the shutter glasses can be freely selected according to actual use requirements.
