The existence of above-mentioned these flaws makes screen seem coarse, influenced attractive in appearancely, particularly the slit between the two adjacent LEDs encapsulation unit exists, and can make dust be easy to enter display screen inside, be deposited on PCB and other electronic component, display screen is caused unpredictable damage.
Summary of the invention
Problem to be solved in the utility model is: a kind of seamless display screen that is applicable to silicon substrate LED is provided, this display screen two adjacent LEDs encapsulation unit can closely cooperate, make and do not have the slit between them basically, prevent that farthest dust from entering display screen inside, make whole screen look more smooth simultaneously.
In order to solve the problems of the technologies described above, the utility model proposes a kind of seamless display screen that is applicable to silicon substrate LED, comprise the LED encapsulation unit, the LED encapsulation unit comprises the led array of being made up of a plurality of LED luminescence unit encapsulation and has the square framework on four limits; Square framework comprises and is used for the lamp hole of packaged LED luminescence unit; Per two adjacent square frameworks link together by the concave-convex connection structure that is located at edge; Described concaveconvex structure is: the edge of the first square framework comprises recess, and the edge of the second square framework comprises the protruding position that can insert described recess.
Preferably: be all recess or protruding position in four limits of square framework on two two adjacent edges.
Preferably: described protruding position is a strip projected parts, and described recess is a strip groove.
Preferably: described convex cross section is a back taper, the back taper groove of described groove for matching with described projection.
Preferably: be packaged with RGB three-primary colours led chip in each LED luminescence unit.
Preferably: the used led chip of each LED luminescence unit comprises that growth substrates is the led chip of silicon substrate.
Preferably: the LED encapsulation unit comprises 8 * 8 LED array of light emitting cells.
The beneficial effects of the utility model are as follows:
Compared to existing technology, the utility model has realized that by the convex-concave syndeton that is provided with the seamless of them is stitched together between the two adjacent LEDs encapsulation unit, such connection, and no matter be up and down, or fore-and-aft direction, because protruding position and recess combination, it is all very compact that the two adjacent LEDs encapsulation unit is connected, make and do not have the slit between them basically, can prevent farthest that dust from entering display screen inside, simultaneously, make whole screen look more smooth, and then prolonged the serviceable life of screen.

Embodiment
The utility model provides a kind of seamless display screen that is applicable to silicon substrate LED, the used led chip of each LED luminescence unit comprises that growth substrates is the led chip of silicon substrate, as: be packaged with RGB three-primary colours led chip in each LED luminescence unit, blue-ray LED wherein and green light LED are that growth substrates is the led chip of silicon substrate.
Referring to Fig. 1 and Fig. 2, the structure of LED display of the present utility model adopts the connecting method among the figure.LED display is made up of a plurality of PCB unit splicings, and each PCB unit is assembled by the LED encapsulation unit 1 that several are welded on the PCB.
Each LED encapsulation unit 1 comprises into a plurality of LED luminescence units 11 of array distribution, and 11 encapsulation of LED luminescence unit are fixed in the lamp hole 1200 of the square framework 12 with four limits.
Referring to structure synoptic diagram of the present utility model shown in Figure 3.This figure has 4 * 4LED luminescence unit on the LED encapsulation unit 1.8 pins that all have a row to be connected with PCB in the upper and lower of each LED encapsulation unit 1, referring to Fig. 4, the root of pin 4 has sealing 6.
Per two adjacent square frameworks link together by the concave-convex connection structure that is located at edge.Concaveconvex structure is: the edge of the first square framework 1201 comprises recess, and the edge of the second square framework 1202 comprises the protruding position that can insert recess.As shown in Figure 3, the edge with recess is defined as cloudy limit, and the edge with protruding position is defined as positive limit.Be all recess or protruding position in four limits of square framework on two two adjacent edges, among Fig. 3, the right of a LED encapsulation unit and bottom are cloudy limit, and the top and the left side are positive limit.
As shown in Figure 4, be specially at the concaveconvex structure between two adjacent square frameworks: sun limit, the top projection (being protruding position) 7 on the top edge 12020 of the second square framework 1202 is set, the cloudy limit groove in the bottom of the strip on the bottom edge 12010 of the first square framework 1201 (being recess) 8, at the side of a LED encapsulation unit 100 the cloudy limit of side groove 800 is arranged, the cloudy limit of side groove is also arranged at the side of the 2nd LED encapsulation unit 101.
The cross section of sun limit, top projection 7 is a back taper, the back taper groove of cloudy limit, bottom groove 8 for matching with sun limit, the top projection 7 of strip.
LED display all is that having a lot is that the individuality of unit is spliced into PCB.And all can have a plurality of LED encapsulation units 1 as shown in Figure 1 to be spliced on each PCB.Going up 4 LED encapsulation units of installation with each PCB is example.Before the assembling, check the pin on each LED encapsulation unit earlier, see if there is askew pin.If have, manually tool using is corrected askew pin, makes on the whole to be consistent.Then 4 LED encapsulation units are stitched together, make in cloudy limit, insertion bottom, the angle point place groove 8 of sun limit, top projection 7 as shown in Figure 4 by framework.Observing pin again has touched crooked in operating process, if having, manually tool using is corrected askew pin again, makes on the whole to be consistent.The welding position that pin is aimed on the PCB inserts, and carries out the pointwise welding.Basically can't see the slit between the LED encapsulation unit that splices like this, and whole panel is also very smooth, can just not rise and fall.
Be illustrated in figure 5 as second kind of structure embodiment of the concave-convex connection structure between per two adjacent square frameworks of the present utility model.This structure shows that the positive limit of LED encapsulation unit is as sun limit, the top among figure projection post 9, and cloudy limit is as cloudy limit, the bottom among figure shrinkage pool 10.Side at the LED encapsulation unit has the cloudy limit of side shrinkage pool 1000.
