The utility model is characterized in that a mask made of arenaceous transparent material is arranged on the outer casing of the LED lamp strip, the mask is made of arenaceous transparent material through double-sided blasting treatment, and adopts an inverse U-shaped structure, a salience is arranged at the upper part of the lamp strip, a groove matched with the salience of the lamp strip is arranged at the lower part of the mask, and the mask and the lamp strip are clipped together through the salience and the groove.
Description
Technical field
The utility model belongs to LED display structure field, and is especially a kind of by on the display screen housing face shield being set, thus make image show soft, color evenly, can produce the LED projection screen of atomizing display effect.
Background technology
LED display shows carrier as a kind of video, and range of application more and more widely.At present, the LED lamp of LED electronic display commonly used is positioned on the outside surface of display screen, because the brightness of LED lamp is very high, the LED display display image is all very dazzling usually, form many visions blind area, the aberration of display image is obvious in addition, and these have all directly influenced the LED display visual effect.Simultaneously, when television relay, when video camera was directly faced display screen, the LED lamp directly stimulated cameraman's eyes, brings very burden to television relay work.
The utility model content
The purpose of this utility model provide a kind of can make image show soft, color evenly, have spraying effect and can produce the LED projection screen of ink and wash pattern display effect.
The technical solution of the utility model is: the LED projection screen, comprise the screen body, and the screen body is provided with LED lamp bar, it is characterized in that the shell of described LED lamp bar is provided with the face shield that the frosted transparent material is made.
Described face shield is to be made by the frosted transparent material through two-sided blasting treatment.
Described face shield is " ∏ " shape structure, is provided with projection on the top of lamp bar, is provided with the groove that is complementary with lamp bar projection in the bottom of face shield, and described face shield and lamp bar are connected together by projection and groove.
The distance of the top of described face shield inwall and LED lamp upper surface is 5-15mm.
Described frosted transparent material is polycarbonate, acrylic or glass.
Effect of the present utility model is: the shell of the LED lamp bar of LED projection screen screen body is provided with the face shield that the frosted transparent material is made, transparent material does not influence the video demonstration of LED display on the one hand, on the other hand after the filtration of the video image of LED display through the frosted transparent material, can produce atomizing effect, the ink and wash that produces on rice paper with ink droplet is the same, make image show softer, color is even, when live telecast, also can not influence photographer's production work again, help television relay.
Below in conjunction with drawings and Examples the utility model is described further.
