Description
Technical field
The utility model is related to ad decoration field, and in particular to a kind of electronics show screen.
Background technology
The LED in LED screen scene plot face and LED gap are generally all array arrangements, and it has certain periodicity.
On common LED screen, because LED light-emitting area is less than physical table area shared by pixel, cause to exist substantially between pixel
The black area that do not light, form latticed periodic structure.And the image pickup device of current photographic equipment is face battle array mostly
CCD, it is likewise supplied with periodic structure, and CCD spatial frequency is compared with the spatial frequency that LED in LED screen is distributed and connect
Closely, so when picture pick-up device shoots LED screen curtain, it may appear that obvious moire fringes phenomenon.And moire fringes phenomenon is not to be clapped
Image required information in itself is taken the photograph, therefore needs to eliminate it.In the not luminous black area of existing elimination and moire fringes phenomenon skill
It is essentially all by installing optical diffusion film or light diffusing sheet additional before LED screen, by carrying out mist to LED light image in art
Change, reduction acutance is handled, add the diffusion effect of certain proportion light spread powder using it not changing luminously the space frequency of black area
Rate cannot not eliminate luminously black area and moire fringes phenomenon.Though existing this technology can solve the problem to a certain extent, it subtracts
Small front amount of light, greatly reduces the brightness of screen, is realized by sacrificing screen-picture, it is not optimal
Solution.
According to above mentioned problem, Chinese patent CN 201511005240.1 discloses a kind of optical lens mirror of LED screens
Guiding device, it is characterised in that the guiding device has several terrace with edge lens consistent with LED quantity on LED screens
Structure and several concavees lens structures consistent with LED lamp quantity, concavees lens structure are used to cover on LED screens
Outside LED lamps, terrace with edge lens arrangement and concavees lens are located at the relative both sides of guiding device respectively.The present invention utilizes concavees lens structure
LED lamp wirings are dissipated, and dioptric imaging is carried out to the light dissipated using terrace with edge lens arrangement, with LED
Lamp both sides form numerous LED lamp shadows as clear zone, the light of LED lamps is spread evenly, can be eliminated between pixel with this
There are problems that the black area that do not light significantly.Simultaneously as foring multiple LED lamp shadows as clear zone, it just changes original
The spatial frequency of LED lamps so that the spatial frequency of LED lamp shadow pictures and CCD spatial frequency variance increase, and then can eliminate
Moire fringes phenomenon.
Above-mentioned patent is to utilize to increase mill dell lens and concavees lens structure before LED, realizes point away from it by lens
Between light filling, but the patent in actual production, it is necessary to set the lens with the number such as LED, therefore can cause production cost and
Installation cost is significantly increased, and is unfavorable for promoting, while lens on light line collects and scattering process with certain, this will also lead
Cause is located at the image that vertical direction is seen immediately ahead of LED screen and its brightness and color with being located at the non-front institute of LED screen
The difference seen.
Utility model content
Based on above mentioned problem, the utility model purpose is that providing one kind does not influence LED luminosity, fills up a little away from sky
Gap, can guarantee that the electronics show screen of acutance again while making image plentiful.
For problem above, there is provided following technical scheme：A kind of electronics show screen, including bottom plate, the bottom plate are provided with
Provided with passivation parting bead between the LED of some equidistant arrangements, the LED, the passivation parting bead is intertwined to form netted knot
Structure is layed between each LED on bottom plate, and beam-splitter, the beam-splitter are provided with the middle part of the passivation parting bead between adjacent LED lamp
Perpendicular to backplate surface.
In said structure, by setting passivation parting bead between LED, to fill the space between LED, in LED
When luminous, the light of LED sidepiece scattering imports passivation parting bead, passivation parting bead is lighted, is filled up with this between each LED not
Light-emitting zone, makes picture color more plentiful while reducing moire fringes.
The utility model is further arranged to, and the beam-splitter two sides, which is provided with, to be used to separate and reflect LED to send light
The minute surface coating of line.
In said structure, beam-splitter is used to separate the light sent between adjacent LED lamp, it is to avoid in the big feelings of contrast
Cause the color between adjacent LED lamp to be mutually affected under condition, wherein setting minute surface coating reflection light on beam-splitter, improve
It is passivated the lightness of parting bead.
The utility model is further arranged to, and the passivation parting bead is translucent material.
In said structure, it is made up in passivation parting bead of light guide agent and epoxy resin, forms it into translucent material and be easy to
Light is imported, and absorbs luminous by light guide agent.
The utility model is further arranged to, and the one side that the passivation parting bead is in contact with bottom plate is provided with reflector layer.
In said structure, reflected by the light for setting reflector layer to be directed to bottom plate, it is to avoid light is absorbed by bottom plate
Influence passivation parting bead illumination effect.
The beneficial effects of the utility model：By the way that passivation parting bead is arranged between adjacent LED lamp, LED is not influenceed
Illumination effect, so that avoid increases the brightness influence that optical diffusion film or light diffusing sheet are caused before LED, utilizes LED
Gap between the light filling adjacent LED lamp that sidepiece is distributed, reduces moire fringes and improves richness and the lightness of picture, together
When have the advantages that production cost is low.
