According to an aspect of the present utility model, a kind of LED display is provided, comprise: the module drain pan, be arranged on printed circuit board (PCB) on the module drain pan, cover the sunshade on the printed circuit board (PCB), sunshade comprises a plurality of grids, is coated with concordant encapsulating layer on a plurality of grids of sunshade.
Further, sunshade also comprises the prominent edge of outstanding raster plane.
Further, the material of sunshade comprises polycarbonate and optical fiber.
Further, the material of encapsulating layer is a silica gel.
Further, adopt integrated through injection molding to be shaped between module drain pan and the sunshade and carry out inferior optical processing.
Further, LED display also comprises the casing that removably connects with the module drain pan.
Further, the front surface of encapsulating layer is provided with the demounting bolt of link block drain pan and casing.
Further, in the interval between the pixel of demounting bolt on encapsulating layer front surface.
Further, LED display also comprises: black labeling lamp is arranged on the printed circuit board (PCB).
Owing to be coated with concordant encapsulating layer on a plurality of grids of sunshade, can not handling as spraying paint, the encapsulating layer do not produce reflective problem, so overcome existing LED display in outdoor reflective problem.The demounting bolt that is provided with between module drain pan and casing has solved the display screen dismounting of prior art, the problem of maintenance inconvenience.
Description of drawings
Constitute this instructions a part, be used for further understanding accompanying drawing of the present utility model and show preferred embodiment of the present utility model, and be used for illustrating principle of the present utility model with instructions.Among the figure:
Fig. 1 shows the spatial structure according to the LED display of the utility model embodiment;
Fig. 2 shows the plan structure according to the LED display of the utility model embodiment;
Fig. 3 shows the main TV structure according to the LED display of the utility model embodiment; And
Fig. 4 shows LED display among Fig. 3 along the sectional structure at E-E place.
Embodiment
Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe the utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Fig. 1 to Fig. 4 shows structure according to the LED display of the utility model embodiment with stereographic map, vertical view, front view and cut-open view respectively.As shown in Figure 1 to Figure 3, the LED display of the utility model embodiment for example is the tabular of rectangle, the size of monolithic LED display can be 240x240x23.5mm, for large-sized LED display, can splice by the LED display of a plurality of such sizes.
As shown in Figure 4, LED display comprises: module drain pan 1, be arranged on printed circuit board (PCB) 6 on the module drain pan 1, cover the sunshade 2 on the printed circuit board (PCB) 6, sunshade 2 is tabular, be provided with the grid of a plurality of rules above, a plurality of grids of sunshade 2 are coated with concordant encapsulating layer 4 on (comprising the hole that each grid surrounds).
Owing to be coated with concordant encapsulating layer 4 on a plurality of grids of sunshade 2, can not handling as spraying paint, encapsulating layer 4 do not produce reflective problem, so overcome existing LED display in outdoor reflective problem.
Further, as shown in Figure 4, sunshade 2 also comprises the prominent along 8 of outstanding raster plane.Prominent along 8 vertical grid planes for example, be shaped as the sheet of rectangle, a plurality of prominent coupling together along 8 form thin edge, and the prominent of sunshade 2 can make LED lamp optical crosstalk not up and down along 8.
Further, the material of encapsulating layer 4 is a silica gel, like this, helps solving reflective problem.
Further, adopt integrated through injection molding to be shaped between module drain pan 1 and the sunshade 2 and carry out inferior optical processing.Encapsulating layer 4 will surpass the height of the raster plane of sunshade, owing to the glue face itself is not given out light, so, solve reflective problem and also helped the flatness that improves sunshade.
Further, the material of sunshade 2 comprises polycarbonate and optical fiber, for example is 85% polycarbonate and 15% optical fiber.This material also helps sunshade 2 prominent can make LED lamp optical crosstalk not up and down along 8, helps adopting between module drain pan 1 and the sunshade 2 integrated through injection molding to be shaped.
During making, printed circuit board (PCB) 6 is fixed on the module drain pan 1, uses fixedly sunshade 2 of screw 5 then, adopt whole encapsulating at last, formed sunshade 2 and module 1 integral structure.
Further, LED display also comprises: the casing (not shown) that removably connects with module drain pan 1.Can hold relevant electrical equipment and circuit in the casing.By removably connecting, can keep in repair LED display.
Further, as shown in Figures 1 to 4, the front surface of encapsulating layer (being the front surface of LED display) is provided with the demounting bolt 7 of link block drain pan 1 and casing.The mode of dismounting has solved the problem that LED display is safeguarded before this, and the mode of back dismounting more in the past saves time, laborsaving.
Further, in the interval between the pixel of demounting bolt 7 on encapsulating layer front surface, promptly demounting bolt 7 is positioned at non-luminous zone of LED display, in order to avoid influence the luminous of LED display and demonstration.
Further, LED display also comprises: black labeling lamp (not shown) is arranged on the printed circuit board (PCB) 6.Like this, make the whole LED display screen more succinct, attractive in appearance.
