Abstract
The utility model discloses a high-definition LED display; wherein, the LED display screen of the display includes a LED display screen body at back of the display screen and a LED light-emitting tube in the front of the display screen. The LED display screen is provided with a layer of optical lens membrane on surface; one side of the LED display screen near the optical lens membrane is a smooth surface; while the other side of the LED display screen is covered evenly with microbead lens. The optical lens membrane can display the dispersed LED luminous points in a magnifying mode, thus forming consecutive integrated spotlight flap, and eliminating the grid effect of luminous points on the LED display screen, which is caused by larger nonluminous regions in the dispersed LED light-emitting tube; in this way, the problem of moire interfering with the picture planes shot by a vidicon is solved, and consecutive high-definition images are formed finally on the surface of the membrane. In addition, the special material of the optical lens membrane meets the requirements of illumination intensity of a studio in light transmittance and hue, and meets the requirements of the vidicon in color temperature and illumination.
Description
Technical field
The utility model relates to a kind of display technique, refers to a kind of high definition LED display device especially.
Background technology
Display area is not big between existing LED display point, brightness is strong excessively, and closely viewing effect is poor, and imaging effect is bad, the same mole line of similar water ripple can occur and reproduce.Especially when taking with video camera, serious mole line phenomenon more can appear in picture, and can glimmer, and there are technological difficulties as teletorium in therefore existing LED screen when especially news category studio scene shows, influences LED applying at teletorium.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of LED display that improves closely to watch and shooting effect, improves image definition, eliminates the high definition LED display device that the mole line disturbs and glimmers.
For reaching above-mentioned technical matters, technical solution of the present utility model is:
A kind of high definition LED display device, its LED display comprise the LED screen body at rear and the LED luminotron in the place ahead, are superimposed with one deck optical lens film on the described LED display surface.
Described optical lens film is a smooth flat near a side of LED display, and opposite side forms and covers uniform microballon lens.
Be connected tension by the titanium hook between described LED display and the optical lens film and fix.
Fixed form between described LED display and the optical lens film is last side suspension, and edged is fixed all around.
Fixed form between described LED display and the optical lens film is that glue is bonding.
After adopting such scheme, because the utility model combines the LED display technique with the radio and television application technology, one deck optical lens film that superposeed on existing LED display surface can amplify demonstration to discrete LED luminous point, finally forms continuous high-definition image on the film surface.In addition, this optical lens film comprises the back casting large screen materials such as DNP, DLP that are applied in the shadow casting technique field, the DNP, the DLP lens coating material that contain the special light absorbent of special ratios by selection, satisfy studio lamp illuminance requirement at aspects such as transmittance, tones, meet video camera and take colour temperature requirement and brightness requirement; Parasitic light is handled, filtered to the some light that described LED luminotron of while sends through the extinction of this optical lens rete, amplify through microballon lens jacket equal proportion again and form continuous whole face light, eliminate between the discrete LED luminotron grid effect of the luminous point on the LED screen that light-emitting zone not causes more greatly, thereby solved the mole line interference problem of video camera shooting picture, made it to become the high definition display device that is applicable to that teletorium uses.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Consult shown in Figure 1, what the utility model was related is a kind of LED display, this display screen 1 comprises the LED screen body 11 at rear and the LED luminotron 12 in the place ahead, key of the present utility model is: described LED display is superimposed with one deck optical lens film 2 on 1 surface, this optical lens film 2 can amplify demonstration to discrete LED luminous point, finally forms continuous high-definition image on the film surface.
And this optical lens film 2 comprises the back casting large screen materials such as DNP, DLP that are applied in the shadow casting technique field, the DNP, the DLP lens coating material that contain the special light absorbent of special ratios by selection, satisfy studio lamp illuminance requirement at aspects such as transmittance, tones, meet video camera and take colour temperature requirement and brightness requirement.On the physical arrangement, requiring the side near LED display 1 is smooth flat simultaneously, and opposite side forms through special processing and covers uniform microballon lens 21.Parasitic light is handled, filtered to the some light that described LED luminotron 12 sends through the extinction of 2 layers of this optical lens films, amplify through 21 layers of equal proportion of microballon lens again and form continuous whole face light, eliminate between the discrete LED luminotron 12 grid effect of the luminous point on the LED screen that light-emitting zone not causes more greatly, thereby solved the mole line interference problem of video camera shooting picture.
In addition, the fixed form that adopts between described LED display 1 and the optical lens film 2 is:
1, the titanium hook connects tension.As shown in Figure 1, this titanium hook 3 takes the shape of the letter U, and it can be fastened in four jiaos of display screen, also can several be fastened in four limits of display screen, thereby optical lens film 2 is fixed on the LED display 1.
2, go up side suspension, edged compresses all around.
3, glue is bonding.
Claims (5)
1, a kind of high definition LED display device, its LED display comprise the LED screen body at rear and the LED luminotron in the place ahead, it is characterized in that: be superimposed with one deck optical lens film on the described LED display surface.
2, a kind of high definition LED display device as claimed in claim 1 is characterized in that: described optical lens film is a smooth flat near a side of LED display, and opposite side forms and covers uniform microballon lens.
