Abstract

The utility model relates to a surface cover of a light emitting diode (LED) display screen. The surface cover comprises a panel, wherein a through hole is formed in each position, which is opposite to each pixel point, on the panel; the whole panel has a grid structure; one or two shading edges are arranged above each row of pixel points on the panel; sawtooth-shaped convex ridges which are transversely arranged and extend towards the front side of the panel are arranged on two edges of each pixel point; a distance between two adjacent sawtooth-shaped convex ridges is 0.7 to 1 mm; each convex ridge consists of a downwards inclined upper edge and an upwards inclined lower edge; the inclination angles of the upper edges and the lower edges are 25 to 30 degrees; and a groove depth between two adjacent convex ridges is 0.8 to 1 mm. Compared with the prior art, the surface cover of the LED display screen has the advantages that due to the design of the shading edges and the convex ridges, dust or rainwater can be effectively prevented from being accumulated on and corroding LED lamp beads; light ray refraction is assisted; the display effect is enhanced; and the service life of the display screen is prolonged.

Description

A kind of LED display face shield

Technical field

The utility model relates to the LED display technical field, is specifically related to a kind of LED display face shield.

Background technology

The LED display of large-scale indoor or outdoor use is made up of a plurality of LED lamps usually, is provided with face shield in LED lamp outside.Existing LED lamp face shield is plane or globoidal structure normally, and its contrast of display degree is poor, and reflective phenomenon often appears in the surface, causes and watches the undesirable of picture.

The utility model content

In order to address the above problem, the utility model provides a kind of LED display face shield that is used for.

The technical scheme of the utility model is following: a kind of LED display face shield; Comprise panel; Corresponding each the pixel position of said panel has through hole, and the whole network that forms of panel is characterized in that; Every capable pixel top is equipped with first and blocks the edge on the said panel, and each pixel both sides is equipped with the transversely arranged zigzag fin that stretches out to panel the place ahead.

The preferred version of such scheme is: the spacing between each bar zigzag fin is 0.7-1mm.

The preferred version of such scheme is: each bar fin is made up of downward-sloping upper edge and acclivitous lower edge, and last following pitch angle is the 25-30 degree.

The preferred version of such scheme is:, the groove depth between each bar fin is 0.8-1mm.

Another kind of preferred scheme is: above every capable pixel on the said panel, also be provided with second and block the edge, second blocks along being positioned at first and blocks along the below.

Further, said second block along extension elongation and block the edge less than first.

Compared with prior art; The beneficial effect of the utility model is following: (1) described LED display face shield blocks the edge through above LED lamp pearl, being provided with; Can effectively prevent dust or rainwater corrosion on the LED lamp pearl; Influence display effect even influence lamp pearl serviceable life, block simultaneously, improve display effect along assisting light refraction; (2) on each pixel both sides the zigzag fin is set, and parameters such as fin angle of configuration the best and spacing, improve ray refractive index, effectively improve display effect, avoid reflective phenomenon, enlarge the visual angle of display screen simultaneously.

Description of drawings

Fig. 1 forms structural representation for the utility model embodiment;

Fig. 2 is an A portion enlarged drawing among Fig. 1.

Embodiment

In order to let those skilled in the art can understand the technical scheme of the utility model better, the utility model is done further to set forth below in conjunction with accompanying drawing.

As shown in Figure 1; The LED display face shield that present embodiment disclosed comprises panel 1; Corresponding each the pixel position of this panel has through hole 10; The whole network that forms of panel, every capable pixel top is equipped with first and blocks edge 2 on the said panel 1, and each pixel both sides is equipped with the transversely arranged zigzag fin 3 that stretches out to panel the place ahead.Each bar fin is made up of downward-sloping upper edge 31 and acclivitous lower edge 32, the downward-sloping 25-30 degree in upper edge, and the lower edge 25-30 degree that is inclined upwardly, upper and lower edge one end pools together the subtriangular fin of composition.Require the spacing between each bar zigzag fin to be controlled at 0.7-1mm, the groove depth between each bar fin is controlled at 0.8-1mm.This design is in order to improve the refractive index of the light that LED lamp pearl sends as far as possible, and reduces the reflection of light rate as far as possible, improves display effect.And make the light that reflects be distributed to all directions of display screen as far as possible, enlarge the visual angle of display screen.

In the practical application; Can above every capable pixel on the panel, be provided with one again and block the edge, second blocks along being positioned at first and blocks along the below, and its extension elongation is blocked the edge less than first; Must be in the visible angle scope; Article two, the design of blocking the edge can effectively keep the sun off for large-scale outdoor LED display screen better effects if, improves viewing effect.

The above-mentioned more excellent embodiment of the utility model that is merely; Under the situation that does not deviate from the utility model spirit and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these changes and distortion all should belong to the protection domain of the appended claim of the utility model.

Claims
