In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Be to be understood that concrete embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, present embodiment provides a kind of LED display device, comprises to led module 101, and described led module 101 is made up of some LED unit, and each LED unit comprises a pcb board 102 and at least one LED light emitting diode 103 and control module thereof; And each LED unit is arranged, so that the present embodiment LED display, the display requirement of the LED display of satisfied most of routine.
The shape of described led module 101 can be set to triangle or its combination or custom-shaped according to the actual requirements, and leg-of-mutton combination can be rectangle, pentagon, hexagon etc., and custom-shaped can be circle, ellipse etc.
Each LED light emitting diode 103 comprises a led chip 105 and an encapsulating structure 104.
As shown in Figure 2,, can adopt the surface coarsening technology, at least one protuberance or recess 202 that the surface coarsening of described led chip 105 is formed for the luminous extraction efficiency that makes described led chip 105 reaches the highest; The perhaps led chip that includes at least one protuberance and at least one recess that the surface coarsening of described led chip 105 is formed.For example, can adopt conventional semiconductors light shield and engraving method or Wet-type etching modes such as (Wet Etching) to come described led chip 105 is carried out surface coarsening.Adopt the surface coarsening technology that alligatoring is carried out on the surface of led chip, not only can carry out alligatoring, can also carry out alligatoring, make led chip 105 have better luminous taking-up efficient the substrate of crystal grain epitaxial layer to the side of the crystal grain epitaxial layer of led chip 105.
In each led chip 105, being shaped as of described protuberance or recess 202 can be taper, circle, ellipse or custom-shaped; Described custom-shaped can be the combination of various regular shapes, for example is circular and the combined shaped of taper or be circle and oval-shaped combination etc.
Described encapsulating structure 104 can be the epoxy resin of using always, and also can adopt is that the silicones of black encapsulates.Silicones is to have highly cross-linked cancellated polysiloxane, has organic tree moon purport and the dual nature of inorganic material concurrently, has unique physical and chemical performance.Because silicones has extraordinary light transmission, thermotolerance, corrosion-resistant and insulativity etc., so silicones can be used for the encapsulating material of LED light emitting diode.And the silicones of black, especially adopt zero luminance or approach zero black silicon resin, not only has good light transmittance, and silicones exerts an influence hardly to the light that the LED light emitting diode sends, therefore, adopt the silicone encapsulation of black, the light that each LED light emitting diode sends is the purest, the transmissivity height, thus make this example LED display display effect best.
In addition; because encapsulating structure 104 not only plays a protective role to led chip; for example; play protective effects such as protection against electric shock, waterproof and dustproof; the light that the material of encapsulating structure 104 itself also can send led chip 104 plays passive influence, for example; light in reflecting extraneous process by total reflection, thereby the light emission rate of LED light emitting diode is reduced.
In order to improve the light extraction efficiency of LED light emitting diode 103, can also form at least one protuberance or recess 201 on the surface of described encapsulating structure 104, so the shape of protuberance or recess 201 can be polygons circular, oval or more than three limits, by changing the surface configuration of encapsulating structure, light is directly reflected outside the encapsulating structure, destroy the total reflection that LED light emitting diode 103 emits beam; And, also can reduce the order of reflection of light in encapsulating structure, reduce absorbed possibility, thereby improve the light emission rate of LED light emitting diode light.
As shown in Figure 3, a positive source line 301, a power-polar curve 303 and at least one signal wire 302 are set on pcb board 102.Positive source line 301 and power-polar curve 303 can provide voltage for each LED unit in the present embodiment, and LED light emitting diode 103 is used for the display light source of LED display as light source.
Described LED light emitting diode 103 can be red LED light emitting diode or blue led light emitting diode or green LED light emitting diode.Described LED light emitting diode can adopt pinned encapsulation, surface-mount type encapsulation or other forms of encapsulation, as, other form encapsulation can encapsulate for Piranha.
