Operation principle is：According to the principle of luminosity of LED light pearl 8, LED display is in the complete white picture of display, and brightness can be with
A very high numerical value is reached, but intrinsic brilliance can not be entirely zero when showing completely black picture, along with LED lamp bead 8 is exposed at
Outside, itself can reflect a part of ambient light, and the contrast of picture is relatively low when making actual use, it is impossible to provide high-quality display
Picture, by the effect of translucent cover and diffusion layer 11, diffusion layer 11 can will directly carry diffusible fine particulate material
Translucent cover upper surface is coated in, for example, light grey or other color blending agents can be used directly to be coated after mixing appropriate glass dust
In translucent cover upper surface, make the brightness deterioration of light-emitting zone center, effectively reduce dazzling sense, picture is become soft, and LED
Lamp bead 8 is not exposed directly, effectively the reflections affect of reduction ambient light, improves the contrast of picture, the side of LED lamp bead 8 is set
Unidirectional transparent film 13 is posted in the upper surface of glass plate 12 put, and the principle of Unidirectional transparent film 13 is the region where Unidirectional transparent film 13
Light intensity be more than the another side of Unidirectional transparent film 13 where region light intensity when, the light of the region of Unidirectional transparent film 13 is difficult
By and be reflected back, the light of the opposite side region of Unidirectional transparent film 13 is easily by the side-emitted of LED lamp bead 8
Light is launched to a, b, c, d, e region respectively, and the light intensity in a regions is less than the light intensity in b regions, the light launched by LED lamp bead 8
C regions are reflexed to by Unidirectional transparent film 13, the light intensity in c regions is consistent with the light intensity in b regions before reflection does not occur, but due to b
The light in region passes through the reflection of Unidirectional transparent film 13, the light intensity in c regions is more than the light intensity in b regions, is launched by LED lamp bead 8
Light d regions are reflexed to by Unidirectional transparent film 13, by that analogy, the light of the side-emitted of LED lamp bead 8 passes through Unidirectional transparent film
Project at interval of 13 reflection between adjacent LED lamp bead 8 so that originally dark space position forms a mixed light region, LED lamp bead
The brightness being spaced between 8 is enhanced, and when needing splicing LED display, can will be connected with the sliding block 2 of block rubber 3
It is embedded in slide block slot 5, now the gap width between LED display is the width of block rubber 3, continues to extrude, the stress of block rubber 3
Deformation is arranged in rubber groove 6, and the magnetic sheet 4 in rubber groove 6 and magnetic sheet 4 on block rubber 3 are attracting, by the position of LED display
Fixed, the heat emission hole 14 on drain pan 1 is conducive to radiating, increases the service life.
