Abstract
The utility model discloses a high-density light-emitting diode (LED) display screen which comprises a box body and a circuit board which is arranged inside the box body, wherein a plurality of LEDs are arranged on the circuit board, the LEDs are arranged in a matrix mode, a space between adjacent LEDs is 1.9mm, and a back plate of the box body is made of aluminum plates. Due to the fact that the design is adopted so that density of the LED display screen is greatly increased, and display effect is clear. The high-density LED display screen meets high demand for display effect by people, and focus on being used for indoor places such as a high-grade commercial district, a studio art hall, a conference room and an exhibition room.
Description
Technical field
The utility model belongs to the display technique field of lighting device, is specifically related to a kind of high density LED display.
Background technology
LED display has been widely applied to the every nook and cranny of life, and its sharpness is more and more higher, and this makes its usability more extensive, and let us can more clearly go to appreciate each and play details.The highdensity product of this class originally just in laboratory or exhibition just as seen, and at present along with the decline of LED cost by more and more client's acceptance, and be widely used in commercial shop, perform in a radio or TV programme the hall, the occasion such as stage lease.Because high density LED display market reaction is strong, the indoor paster screen of traditional 4mm or 3.5mm has not satisfied client's demand, and they wish to have more highdensity LED display to reach more clearly display effect.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of high density LED display is provided, the not high technical matters of density when it can solve existing display screen use.
The technical scheme that the utility model adopts is: a kind of high density LED display, the wiring board that comprises casing and this box house, be provided with a plurality of light emitting diodes on the described wiring board, described light emitting diode is matrix form and arranges, and spacing is 1.9mm between adjacent light emitting diode, and the backboard of described casing is made by aluminium sheet.
As preferably, the bonnet of described casing is made by the PC material.
As preferably, chip package adopts the QFN encapsulation on the described wiring board.
As preferably, brace adopts the hand-wring type screw to fix on the described casing.
The beneficial effects of the utility model are: because LED display of the present utility model adopts above-mentioned design, the density of LED display is increased greatly, the effect that shows is more clear, satisfy people for the higher demand of display effect, emphasis is used for high-grade commercial block, performs in a radio or TV programme the various indoor scenarios such as hall, meeting room, exhibition room.
Description of drawings
Fig. 1 is the utility model structural representation one;
Fig. 2 is the utility model structural representation two.
Among the figure: 1, casing; 11, backboard; 12, bonnet; 2, wiring board; 3, light emitting diode.
Embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of high density LED display, the wiring board 2 that comprises casing 1 and this casing 1 inside, be provided with a plurality of light emitting diodes 3 on the described wiring board 2, described light emitting diode 3 is matrix form and arranges, and 3 spacings of adjacent light emitting diode are 1.9mm, and the backboard of described casing 1 11 is made by aluminium sheet, and hardness is higher.
Because LED display of the present utility model adopts above-mentioned design, the density of LED display is increased greatly, the effect that shows is more clear, satisfies people for the higher demand of display effect, and emphasis is used for high-grade commercial block, performs in a radio or TV programme the various indoor scenarios such as hall, meeting room, exhibition room.
The bonnet 12 of described casing 1 is made by the PC material, and is not only attractive and durable, and greatly reduces the weight of casing 1.Chip package adopts the QFN encapsulation on the described wiring board 2, good heat dissipation not only, and can greatly reduce chip volume.Brace adopts the hand-wring type screw to fix on the described casing 1, is easy to adjust casing 1 flatness, is easy to installation and removal.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, the equivalence of namely doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
