Abstract
The utility model discloses a moire pattern eliminating device for light-emitting diode (LED) display screen. The moire pattern eliminating device for LED display screen comprises a frame used for installing the LED display screen and a moire pattern resisting film which is connected with the frame, wherein the frame comprises a back frame and side plates which are connected with the back frame in a vertical mode. The side plates at least comprise two side plates which are oppositely arranged, and at least one side plate is an upper side plate. A side face of the moire pattern resisting film is fixedly connected with the side plates of the frame, and the moire pattern resisting film is arranged before the LED display screen in a parallel mode. One face, opposite to the LED display screen, of the moire pattern resisting film is a frosted face, the other face, opposite to the frosted face of the moire pattern resisting film is a smooth face. The moire pattern eliminating device for LED display screen is capable of effectively eliminating a moire pattern, so an image is enabled to be clear and real.
Description
Technical field
The utility model relates to the LED display technical field, and specifically a kind of LED display is eliminated the moire fringes device.
Background technology
In broadcast television industry; LED display often can be applied to each live news Room or perform in a radio or TV programme in the middle of the Room; when video camera in performing in a radio or TV programme the Room is taken picture take LED display as background; the water ripples of wave-like in various degree can appear in LED display in video camera and monitor, we are referred to as moire fringes to this.Moire fringes is a kind of performance of beat principle.Two constant amplitude sinusoid stacks that frequency approaches, the amplitude of composite signal will change according to the poor of two frequencies.During beat principle is widely applied to radio and television and communicates by letter, be used for frequency conversion, modulation etc.If photo-sensitive cell CCD(CMOS) spatial frequency of striped approaches in the spatial frequency of pixel and the image, will produce moire fringes.The generation of moire fringes has had a strong impact on the clear of image.
Affect clearly problem of figure in view of above-mentioned existing LED display produces moire fringes, the design is actively studied and is innovated, and has has finally researched and developed a kind of LED display and has eliminated the moire fringes device, can effectively eliminate moire fringes, makes image more clear, true.
The utility model content
In order to solve the above-mentioned problems in the prior art, the utility model provides a kind of LED display to eliminate the moire fringes device, can effectively eliminate moire fringes, makes image more clear, true.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
LED display is eliminated the moire fringes device, comprise for framework and the anti-moire fringes film that is connected with framework that LED display is installed, described framework comprise back rack and with back rack side plate connected vertically, described side plate comprises two side plates that relatively arrange at least, and at least one side plate is epipleural, the side of described anti-moire fringes film is fixedly connected with the side plate of framework, described anti-moire fringes film is set in parallel in LED display the place ahead, the described anti-moire fringes film one side relative with LED display is frosting, and the another side relative with frosting is shiny surface.
Further, the vertical range of the end face of the epipleural of described framework and LED display is no less than 3mm.
Further, the distance of described anti-moire fringes film and LED display is 1～3mm.
Further, the side of described anti-moire fringes film is connected with framework by screw or connection snap close.
Further, be connected by the chute slide block device that is oppositely arranged between described LED display and the framework.
Further, described anti-moire fringes film is made of with the refractor and the photic zone that are divided into the substrate layer both sides the substrate layer of centre, and wherein photic zone is towards LED display one side setting.
Further, described substrate layer is that polyethylene terephthalate (PET) is made.
Compared with prior art, the beneficial effects of the utility model are:
The whole outside of LED display of the present utility model and inner structure are succinctly attractive in appearance, are easy to the I﹠ M operation.Eliminated moire fringes, the image color high conformity, undistorted.The utility model is placed a whole anti-moire fringes film in the LED display dead ahead, one side is smooth transparent surface, one side is thin frosting, thin frosting is towards display screen, outside the shiny surface punching, video camera is effectively eliminated moire fringes after monitor is taken in display screen display frame (after rough thin frosting, diffuse reflector, anti-reflective layer processing).
Description of drawings
Fig. 1 is the structural representation that LED display of the present utility model is eliminated the moire fringes device;
Fig. 2 is the layer structural representation of anti-moire fringes film of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail, but not as to restriction of the present utility model.
Fig. 1 is the structural representation that LED display of the present utility model is eliminated the moire fringes device; Fig. 2 is the layer structural representation of anti-moire fringes film of the present utility model.As depicted in figs. 1 and 2, LED display is eliminated the moire fringes device, comprises for framework 3 and the anti-moire fringes film 1 that is connected with framework 3 that LED display 2 is installed.LED display 2 is connected by the chute slide block device 5 that is oppositely arranged with framework 3, and wherein 3 one of LED display 2 and frameworks are provided with slide block, and another is provided with chute.Framework 3 comprise back rack 301 and with back rack 301 side plates connected vertically, side plate comprises two side plates that relatively arrange at least, and at least one side plate is epipleural 302, and the side of anti-moire fringes film 1 is fixedly connected with the side plate of framework, and anti-moire fringes film 1 is set in parallel in LED display 2 the place aheads.Anti-moire fringes film 1 one side relative with LED display is frosting, and the another side relative with frosting is shiny surface.On the back rack 301 relative epipleural and lower side panel can only be set.Epipleural and the left plate that is oppositely arranged also can be set and side plate is arranged.Epipleural, lower side panel, left plate also can be set simultaneously and side plate is arranged.The epipleural 302 of framework 3 is no less than 3mm with the vertical range of the end face of LED display 2.Anti-moire fringes film 1 is 2mm with the distance of LED display 2.The side of anti-moire fringes film 1 is connected with framework 3 by screw 4.Perhaps be provided with suitable slot at framework, anti-moire fringes film is plugged in the slot.Or connect such as the mode that connects snap close etc. and be fit to by other.Anti-moire fringes film 1 is made of with the refractor 101 and the photic zone 103 that are divided into the substrate layer both sides the substrate layer 102 of centre, and wherein photic zone is towards LED display one side setting.Substrate layer is that polyethylene terephthalate (PET) is made.Light see through anti-moire fringes film can with the different medium of refractive index in pass so that the phenomenon of many refractions, reflection and scattering occurs light, can revise the effect that light becomes uniform area light source to spread to reach optics.
