Screen, is all to have added very thick safety glass on surface, but thick safety glass can produce refraction, influence display effect, while glass
The skid resistance of glass is low, especially when adhere to upper water after, be more easy to allow people to slide into, produce certain danger, availability is relatively low.
The content of the invention
The purpose of this utility model is to provide a kind of with protecting cover LED display, is provided for display screen surface higher
Security protection, it is possessed higher waterproof ability, improve the degree of protection of display screen, possess under outdoor or relatively rugged environment
Use, while can be walked with someone, trample, there is extremely strong skid resistance, be not easy to slide into after getting wet.
The purpose of this utility model is achieved through the following technical solutions：
A kind of with protecting cover LED display, including circuit board 1 and soldered circuit board 1 are in the LED 2 on circuit board 1
The array of composition, including the PC protective covers 3 for protecting LED 2 are covered on circuit board 1；
The downwardly projecting horizontal bar 31 of described PC protective covers 3 forms grid array with vertical bars 32, and a LED is set in each grid
Lamp 2.
The described lower section of PC protective covers 3 sets pressure sensor 4, the top pressure of detection PC protective covers 3.
A kind of band that the utility model embodiment provides it can be seen from above-mentioned technical scheme provided by the utility model is anti-
The LED display of shield, higher security protection is provided for display screen surface, it is possessed higher waterproof ability, improved aobvious
The degree of protection of display screen, possess and used under outdoor or relatively rugged environment, while can be walked with someone, trampled, had extremely strong
Skid resistance, it is not easy to slide into after getting wet.

Obtain other accompanying drawings.
Fig. 1 is the cross-sectional view for the with protecting cover LED display that the utility model embodiment provides；
Fig. 2 is the planar structure schematic diagram for the with protecting cover LED display that the utility model embodiment provides；
Fig. 3 is the close-up schematic view of drawing.
Embodiment
With reference to the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu, it is fully described by, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole realities
Apply example.Based on embodiment of the present utility model, those of ordinary skill in the art are obtained under the premise of creative work is not made
The every other embodiment obtained, belongs to the scope of protection of the utility model.
The utility model embodiment is described in further detail below in conjunction with accompanying drawing.
Embodiment one
As shown in Fig. 1 to Fig. 3, a kind of with protecting cover LED display, including circuit board 1 and soldered circuit board 1 are in electricity
The array of the lamp of LED 2 composition on road plate 1, it is characterised in that LED 2 is protected on circuit board 1 including covering in
PC protective covers 3；The downwardly projecting horizontal bar 31 of described PC protective covers 3 forms grid array with vertical bars 32, and one is set in each grid
LED 2.Horizontal bar 31 and vertical bars 32 its can be processed into the mesh shape of suitable dimension according to the size and spacing of LED 2, be buckled in
The surface of circuit board 1 under LED 2, there is a LED 2 in each grid, separately protection, while each horizontal bar of grid
31 and all equivalent to one reinforcements of vertical bars 32 be used for the transmission for bearing pressure on surface.
The described lower section of PC protective covers 3 sets pressure sensor 4, the top pressure of detection PC protective covers 3.Realize man-machine mutual
It is dynamic, it is the mode that the offer of display screen is more applied.
Protective cover printing opacity as display screen is its primary requirement, and otherwise display screen will lose its effect, currently used
Material mainly includes safety glass, PMMA and PC materials.PC materials are chosen in this example, PC materials are makrolon, are molecules
High molecular polymer containing carbonate group in chain, aliphatic, aromatic series, aliphatic-fragrance can be divided into according to the structure of ester group
The polytypes such as race.Wherein because the mechanical performance of aliphatic and aliphatic-aromatic makrolon is relatively low, so as to limit it
Application in terms of engineering plastics.Only aromatic copolycarbonate obtains industrialized production at present.Due to polycarbonate structure
On particularity, as the most fast general engineering plastic of growth rate in five large-engineering plastics.
PMMA is polymethyl methacrylate, is referred to as acrylic compounds with the polymer obtained by acrylicacidandesters Type of Collective
Resin, corresponding plastics are referred to as polyacrylic plastics, wherein most widely used with polymethyl methacrylate.Polymethyl
Sour methyl esters abbreviation code name be PMMA, is commonly called as lucite, is that to synthesize quality in transparent material so far most excellent, price ratio again
Convenient kind.
Protective cover printing opacity as display screen is its primary requirement, and otherwise display screen will lose its effect, currently used
Material mainly includes safety glass, PMMA and PC materials.
In load-bearing and impact resistance, all materials can increase its load-bearing anti-pressure ability by increasing thickness,
Increase thickness is then possible to produce refraction, influences visual angle, for material itself, PMMA is more crisp, and impact resistance is poor；Steel
It is high to change center of glass field strength, it is more more crisp toward edge, whole glass fragmentation faced is easily caused when especially corner location is thumped；
PC materials have extremely strong impact resistance in itself, non-breakable.
Display screen is mated formation on ground, is had substantial amounts of people and is walked above, therefore the protection material of display screen surface will have
There is extremely strong skid resistance, otherwise being slided into above may cause pedestrian to slide into injury, and safety glass and PMMA surface are smooth, especially
It is easier to slide into after getting wet, and the masks of PC materials has been compared with PMMA incomparable in non-skid property with safety glass
Advantage.
Protective cover is molded, PC and PMMA easy processings, can need to be processed into different models, safety glass according to user
Generally block, the difficulty for being processed into different models is big.
Three kinds of materials compare：
The shield of PC materials is easily combined with materials such as waterproof aprons, and higher security protection is provided for display screen surface, is made
It possesses higher waterproof ability, improves the degree of protection of display screen, possesses and is used under outdoor or relatively rugged environment.
Consider that safety glass and PMMA are not suitable for the use of platform ground control system from security standpoint and practical application,
PC materials are the optimal selection of system display surfacecti proteon cover.
It is described above, the only preferable embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model discloses
Change or replacement, should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should
It is defined by the protection domain of claims.
