Abstract
The invention provides a face shield for an LED display screen, comprising a base body and an apparent surface arranged on the base body, wherein the apparent surface comprises a plurality of high shading edges and low shading edges, and light-absorbing black gaps are formed between the high shading edges and the low shading edges. The apparent surface of the face shield for the LED display screen is made of black matte TPU elastomer and absorbs large amount of luminous light or sunlight through the black light-absorbing black gaps and small light-absorbing gaps, thereby decreasing the glare production to a large extent and increasing the contrast grade.
Description
Technical field
The present invention relates to the LED display field, especially a kind of LED display face shield that has improved.
Background technology
The range of application of LED display more and more widely, it can be applicable to various occasions such as indoor outer advertisement, physical culture, traffic, performance, exhibition, lease, rally.At present, the paster LED display screen has become the main product of indoor medium and high level LED display with advantages such as its high resolving power, high brightness, visual angle are big, and is applied to gradually in the high-end product of outdoor LED screen.Because the resolution of paster LED display screen is higher, and the height of the relative PCB of paster LED lamp body is less, therefore, face shield to the paster LED display screen requires very strict, generally speaking, the LED display face shield need make the visible angle of LED display increase, and can prevent that houselights or sunshine from forming reflect and cause reducing display quality on LED display.Yet, present paster LED display screen face shield generally adopts construction materials such as PC and surface not to do extinction, counnter attack optical processing, and when illumination light or solar radiation were to the screen body of LED display, shielding honorable cover can reflect, cause glare phenomenon, reduced contrast.
Therefore, provide a kind of real necessity that belongs to of LED display face shield that can prevent dazzle and improve contrast.
Summary of the invention
The purpose of this invention is to provide a kind of LED display face shield, be intended to solve existing LED display face shield and can not effectively prevent dazzle, the defective that contrast is lower.
The present invention is achieved in that a kind of LED display face shield, and it comprises matrix and the appearance that is arranged on the matrix, and described appearance comprises some high shading edges and low shading edge, forms the black seam of extinction between described high shading edge and the low shading edge.
More specifically, described matrix is that fiberglass reinforced PC engineering plastics are made.
More specifically, described appearance is made by the mute light TPU elastomeric material of black.
More specifically, described high shading edge and low shading edge is by pinnacle of shaping, two inclined-planes.
More specifically, a high shading edge and a low shading are along forming one group of shading edge, and two groups of shadings are provided with some zigzag denticles along the centre.
More specifically, form some little extinction seams between described some zigzag denticles.
More specifically, described matrix and appearance adopt double color injection technology single injection-molded.
Compared with prior art, LED display face shield provided by the invention adopts the mute light TPU elastic body of black to make appearance, simultaneously by black seam of extinction and a large amount of illumination light or the sunlight of absorbing of little extinction seam, the minimizing of very big degree the generation of dazzle, improved contrast.
Description of drawings
Fig. 1 is the one-piece construction synoptic diagram of LED display face shield of the present invention;
Fig. 2 is along the cut-open view of A-A profile line among Fig. 1;
Fig. 3 is the structure enlarged diagram of appearance involved in the present invention.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
In conjunction with referring to shown in Fig. 1, Fig. 2, Fig. 1 is the one-piece construction synoptic diagram of the preferred embodiment of LED display face shield 1 of the present invention, Fig. 2 is the cut-open view along A-A profile line among Fig. 1, described LED display face shield 1 comprises fiberglass reinforced PC (polycarbonate) engineering plastics matrix 3 and mute light TPU (Polyurethane Thermoplastic Elastomer) the elastomeric material appearance 2 of black, in conjunction with referring to shown in Fig. 3, described appearance 2 comprise high shading along 4, low shading along 5, by high shading along 4 and low shading stitch 8 along the black seam 6 of 5 extinctions that form, some zigzag denticles 7 and little extinction.
Matrix 3 and appearance 2 adopts double color injection technology single injection-moldeds, high shading along 4, low shading is along 5 by the pinnacle that is shaped, two inclined-planes, high shading forms the black seam 6 of an extinction with low shading along 4 in the middle of 5; Zigzag denticle 7 forms a pinnacle by two wide-angle inclined-planes, forms a little extinction seam 8 between two adjacent zigzag denticles 7.LED display face shield 1 of the present invention comprises the black seam 6 of many extinctions and many little extinction seams 8 from top to bottom.
Because two-color injection-molded scheme has been adopted in the preferred embodiment of LED display face shield 1 of the present invention, the base material 1 of face shield adopts fiberglass reinforced PC engineering plastics, and appearance 2 adopts the mute light TPU elastic body of black, can effectively avoid dazzle, simultaneously, face shield appearance 2 has one group of one high and one low level shadow from top to bottom along (high shading is along 4 between each pixel, low shading is along 5), per two groups of shadings have zigzag denticle 7 along the centre, stitch 8 and form a little extinction between the adjacent zigzag denticle 7, the top on all shading edges is a wedge angle, can absorb illumination light or sunlight in a large number by black seam 6 of extinction and little extinction seam 8, also greatly the minimizing of degree the generation of dazzle, improved contrast.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention.For example, high shading along 4 and the concrete arrangement mode of low shading along 5 be not limited to shown in the figure, all any modifications of being done within the spirit and principles in the present invention, be equal to and replace and improvement etc., all should be included within the protection domain of claim of the present invention.
Claims (7)
