Fig. 1 is the diagrammatic cross-section of a kind of LED display module according to an exemplary embodiment.This LED shows module and comprises:
Substrate 110 can be the metal base plate with heat-sinking capability.
Be positioned at the LED array on substrate 110, it is positive integer that LED array comprises n LED 130, n.Each LED 130 can be LED identical mutually, also can be mutually different LED.
Be positioned at the optical waveguide layer 150 on substrate upper strata, optical waveguide layer 150 have and n each self-corresponding n through hole 152 of LED 130.Optical waveguide layer 150 adopts light-proof material.
Be positioned at the semi-transparent film 170 on optical waveguide layer 150 upper strata.
Be positioned at the photic zone 190 on semi-transparent film 170 upper strata.
In sum, the LED that the present embodiment provides shows module, by arranging optical waveguide layer and semi-transparent film, making when LED array is not luminous, only can see the entirety that photic zone and semi-transparent film are formed, and cannot see LED from external environment condition; Meanwhile, when LED array light-emitting, due to the optically focused effect of through hole and the diffuse reflection effect of semi-transparent film, can make again photic zone to be formed clear, bright luminous point.
Incorporated by reference to reference to figure 2A and Fig. 2 B, which respectively show the exploded perspective view and the blast sectional view that show module according to a kind of LED shown in another exemplary embodiment.This LED shows module and comprises:
Substrate 110 can be the metal base plate with heat-sinking capability.
Be installed on the LED array on substrate 110, it is positive integer that LED array comprises n LED 130, n.Each LED 130 can be LED identical mutually, also can be mutually different LED, and such as, wherein a part of LED is red LED lamp, and another part LED is yellow light LED lamp.
Alternatively, LED 130 is n the LED of evenly arranging according to the even row and column of row and column.Alternatively, LED array 130 comprises n the LED according to character trace or the arrangement of display track spacing.The present embodiment does not make the arrangement mode of LED array 130 and changes.
Be positioned at the optical waveguide layer 150 on substrate upper strata, optical waveguide layer 150 have and n each self-corresponding n through hole 152 of LED 130.Also namely, each LED 130 is to there being 1 through hole 152.The aperture of through hole 152 is more than or equal to the external diameter of LED 132.Optical waveguide layer 150 adopts light-proof material usually.In order to prevent, between optical waveguide layer 150 and semi-transparent film 170, light leak occurs, alternatively, optical waveguide layer 150 has flexible contact face.Alternatively, optical waveguide layer 150 is layer of silica gel.
As a kind of possible embodiment, the degree of depth of through hole 152 is deeper than preset value, to provide good heat radiation for LED 130.As the embodiment that another kind is possible, the inside surface of through hole 152 forms reflective surface, to reduce the loss of the light that LED 132 sends as much as possible.Meanwhile, the size and shape of the present embodiment to through hole 152 does not limit, and can be circle, strip, ellipse, square and other polygon.
Be positioned at the semi-transparent film 170 on optical waveguide layer 150 upper strata, and be positioned at the photic zone 190 on semi-transparent film 170 upper strata.
Photic zone 190 normally glassy layer, such as ultra-clear glasses.Photic zone 190 can also be clarity plastic layer.Semi-transparent film 170 can be plastic foil, or semi-transparent film 170 is by screen printing mode, the ink layer of silk-screen in the one side of glassy layer 190 towards optical waveguide layer 150.
This ink layer can for not having the ink layer of any pattern uniformly.Alternatively, region not corresponding with through hole 152 on this ink layer is formed with pattern, and the concrete form of pattern is not limit.
Alternatively, this LED display module also includes LED drive circuit and control circuit (not shown).LED drive circuit and control circuit can control separately in the on off state of each LED 132 in LED array, the duty such as luminance state and color state one or more.
Can be fixedly connected with by glue between above-mentioned each layer, also can by the component crimping such as bolt, housing together.The present embodiment is not limit the connected mode between above-mentioned each layer.
When the whole LED 130 in LED array are not luminous, due to the existence of semi-transparent film 170, when user observes photic zone 190, only can observe inherent color and the pattern of semi-transparent film 170.Also namely, user cannot observe the LED 130 be positioned at below semi-transparent film 170.
When the whole LED 130 in LED array or part LED 130 are in luminescence, due to the diffuse reflection effect of semi-transparent film 170, the light that LED 130 sends can form sharp-edged luminous point on semi-transparent film 170, and the shape of this luminous point is consistent with the shape of through hole 152.If through hole 152 is circular, then luminous point is circular light spot; If through hole 152 is hexagon, then luminous point is hexagon luminous point.When user observes photic zone 190, the luminous point that each luminous LED is formed on semi-transparent film 170 can be observed.It should be noted that, if do not have semi-transparent film 170, when part LED is luminous, photic zone 190 entirety can be luminous, and can not form luminous point.
These luminous points can be only decoration function, or, the shape that these luminous points can be combined into character, digital equivalent-load has information.Such as, with reference to figure 2C, from left to right respectively illustrate: all not luminous, a part of LED of LED is luminous, another part LED is luminous, all LED is all luminous schematic diagram.
In sum, the LED that the present embodiment provides shows module, by arranging optical waveguide layer and semi-transparent film, making when LED array is not luminous, only can see the entirety that photic zone and semi-transparent film are formed, and cannot see LED from external environment condition; Meanwhile, when LED array light-emitting, due to the optically focused effect of through hole and the diffuse reflection effect of semi-transparent film, can make again photic zone to be formed clear, bright luminous point.
Above-mentioned LED shows module and can realize becoming the display section in various electronic equipment, or above-mentioned LED shows module and can realize separately becoming LED matrix display.Disclosure embodiment does not limit this.
Those skilled in the art, at consideration instructions and after putting into practice invention disclosed herein, will easily expect other embodiment of the present disclosure.The application is intended to contain any modification of the present disclosure, purposes or adaptations, and these modification, purposes or adaptations are followed general principle of the present disclosure and comprised the undocumented common practise in the art of the disclosure or conventional techniques means.Instructions and embodiment are only regarded as exemplary, and true scope of the present disclosure and spirit are pointed out by claim below.
