Abstract

The invention relates to an LED display pattern assembly with high contrast, which comprises a box-shaped outer casing and a circuit board attached with a plurality of LED chips; the circuit board is arranged in the outer casing, a plurality of holes are arranged on the outer casing, the positions of the holes are corresponding to the positions of the LED chips on the circuit board; and semi-transparent black gum is poured between the circuit board and the outer casing. By adopting the LED display pattern assembly with high contrast of the technical proposal of the invention, the LED display pattern assembly with high contrast has blacker chroma when displaying black because the black gum can shade the reflected light of the circuit board, , thereby effectively enhancing the contrast and improving the displaying effect.

Description

A kind of high-contrast LED shows module
Technical field
The present invention relates to LED and show module, particularly a kind of high-contrast LED shows module.
Background technology
LED display technical development in the last few years is very fast, and we have seen increasing outdoor large screen LED display.LED display all is to show that by several LED module constitutes, so LED shows that the display effect of module has determined the display effect of LED display.LED shows that module generally comprises a box-like shell, a circuit board that is pasted with some led chips, and the position of the corresponding led chip of outer surface of outer cover offers the hole of some circles.Touch by the hole of high tempreture tape during assembling, then circuit board is put into shell, again encapsulating case surface.But the contrast of present LED display is all lower, this is because present LED shows module, for the light that allows led chip send appears, all be to adopt water white glue to pour into now, this has just caused, and near the white the led chip can be in sight on the circuit board, thereby the LED of this kind mode shows module when not working, and have very high surface area is white, reflective strong under the irradiation of outdoor natural light line, cause LED to show that the contrast of module reduces.Especially when LED display shows black, make blackness not enough, have a strong impact on the display effect of LED display.
Summary of the invention
The LED that technical matters to be solved by this invention provides a kind of high-contrast shows module, and it has higher contrast, to promote display effect.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of high-contrast LED shows module, comprising: box-like shell is pasted with the circuit board of some led chips; Described circuit board setting and offers several holes, the position of the position corresponding circuits onboard led chip in described hole in the enclosure on the shell; Irritate between described circuit board and the shell translucent black glue is arranged.
Adopt the high-contrast LED of technical solution of the present invention to show module, the beneficial effect that is compared with the prior art is:
Because black glue can shelter from the reflective of circuit board, make high-contrast LED show that module colourity when showing black is more black, thereby effective enhancing contrast ratio promote display effect.
Embodiment
The LED that this embodiment provides shows module, comprising: a box-like shell, and a circuit board that is pasted with some led chips, the position of the corresponding led chip of outer surface of outer cover offers some holes.Touch by the hole of high tempreture tape during assembling, then circuit board is put into shell, pour into translucent black glue again case surface.Because black glue looks like black, thereby make LED show that module colourity when showing black is more black, thus effective enhancing contrast ratio.And black glue is translucent, though black glue can absorb a part of light, causes brightness to reduce, and can not influence use so that most of ray cast that led chip sent is come out.
Further, also square hole is arranged in the hole on the shell,, is made LED show that the contrast of module is higher with increasing specific surface area.
The glue of the black preferred normal temperature cure of glue, thus do not need to carry out hot setting, thereby can not make shell and wiring board shrink inconsistent and the generation buckling deformation.
Also having another way is wall and circuit board painted black with the hole, in theory also can enhancing contrast ratio, but because present LED shows module, its each pixel comprises several led chips, carries out mixed light with this, thereby demonstrates multiple color.This just causes the position of LED modules with different colors chip and black wall different, thus the absorption coloured light that the wall of black can not equivalent, thus can cause the colour mixture of LED lamp to go wrong, thereby be further improved.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.

Claims (3)

1, a kind of high-contrast LED shows module, comprising: box-like shell is pasted with the circuit board of some led chips; Described circuit board setting and offers several holes in the enclosure on the shell, the position of the position corresponding circuits onboard led chip in described hole is characterized in that, irritating between described circuit board and the shell has translucent black glue.
2, a kind of high-contrast LED as claimed in claim 1 shows module, it is characterized in that described black glue is normal temperature cure glue.
3, a kind of high-contrast LED as claimed in claim 1 or 2 shows module, it is characterized in that the hole on the described shell is a square hole.
