Abstract
The utility model discloses a kind of high density LED ground display screen, this display screen comprises screen body, bracing frame, protective cover and heat dissipation equipment, bracing frame is installed on the ground, for supporting described screen body, screen body is arranged on the top of bracing frame, and protective cover is arranged on the upper surface of screen body, for the protection of screen body, heat dissipation equipment is arranged on the below of screen body, is the heat radiation of screen body; The ground display screen of the application not only achieves the display of high-resolution, and the serviceable life of equipment obtains significant raising, even if still can ensure to reach certain resolution when showing area and being less.
Description
Technical field
The utility model relates to ground display screen field, particularly relates to a kind of high density LED ground display screen.
Background technology
At present, LED ground display screen is a little bigger clearance display screen, and its picture element density is not high, and sharpness is not high, and display effect is bad, can not meet people to high-resolution display effect pursuit.In addition, existing ground display screen panel is plastics and approximate material makes, and hardness is low, wearing quality extreme difference, and transparency is also bad, and very easily variable color, have a strong impact on display effect.Therefore, the effect how realizing high-resolution display and the serviceable life of how to improve product become those skilled in the art's problem anxious to be resolved.
Utility model content
For Problems existing in background technology, the purpose of this utility model is to provide a kind of high density LED ground display screen, and this ground display screen not only increases the sharpness that ground screen display is shown, improves the serviceable life of equipment simultaneously.
The purpose of this utility model is achieved through the following technical solutions:
A kind of high density LED ground display screen; this display screen comprises screen body, bracing frame, protective cover and heat dissipation equipment; support frame as described above is installed on the ground; for supporting described screen body; screen body is arranged on the top of bracing frame, and described protective cover is arranged on the upper surface of screen body, for the protection of screen body; described heat dissipation equipment is arranged on the below of screen body, is the heat radiation of screen body.
Further, between described screen body and protective cover, be provided with transparent damping pad, for cushioning because protective cover is under pressure to the extruding of screen body.
Further, described screen body is that picture element density is at 20000 points/m
2above Full color LED display screen.
Further, the luminotron of described screen body is direct plug-in type light emitting pipe or SMD luminotron.
Further, described protective cover is tempered glass protective cover.
Further, the seamed edge of described tempered glass protective cover has 45 ° of chamferings, and the edge of described tempered glass protective cover and described screen body is sealed by clear glass glue.
Further, support frame as described above is supporting frame with steel structure or aluminium section bar bracing frame.
Further, described heat dissipation equipment is blower fan or air conditioner.
The utility model has following positive technique effect:
The technical scheme of the application, owing to have employed highdensity display screen, achieves the effect of ground display screen high-resolution display, and obtains significant raising serviceable life.Can ensure to reach certain resolution when showing area and being less, thus ensure that display effect.Tempered glass protective cover is directly mated formation on a display screen, reduces the distance between luminotron and glass to greatest extent, and make display more clear, color reducibility is better.Because the hardness of protecting glass is very high, wearing quality is fine, can use for a long time, only needing to change glass ground, and must need not changing together with screen body as existing ground display screen, therefore saving the expense of maintenance when wearing and tearing too serious.This kind of display frame occurs with the form of assembly, and structure, at produce in factory, ensure that the making precision of assembly and the fastness of installation, and can make it commercialization production.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As Figure 1-5; ground display screen of the present utility model comprises screen body 1, bracing frame 2, protective cover 3 and heat dissipation equipment 4; wherein; bracing frame 2 is installed on the ground, and for support screen body 1, screen body 1 is arranged on the top of bracing frame 2; protective cover 3 is arranged on the upper surface of screen body 1; for the protection of screen body 1, heat dissipation equipment 4 is arranged on the below of screen body 1, for screen body 1 dispels the heat.
Preferably, the screen body 1 in the application is that picture element density is at 20000 points/m
2above Full color LED display screen, certainly, the bracing frame 2 in the application and protective cover 3 etc. are not limited to Full color LED display screen; And the luminophor (i.e. light emitting diode) shielding body 1 used can be not only direct plug-in type light emitting pipe, also can be SMD luminotron.Screen body 1 comprises: top layer is welded with light emitting diode and backing weld has the pcb board 7, face shield 6, bracket 5, Switching Power Supply, control card, connection wire etc. of electronic devices and components, and wherein the material of face shield 6 and bracket 5 is preferably plastic material; The one side covering that pcb board 7 is welded with light emitting diode is provided with face shield 6, another side installation bracket 5; In addition, display screen display section is installed with the form of modular unit, so that maintenance, reduces the scope starting protective cover 3.
Bracing frame 2 in the application is made up of steel construction, aluminium profile structure or other materials with high strength, and bracing frame 2 for support screen body 1 and protective cover 3, and installs the equipment such as Switching Power Supply, heat dissipation equipment 4.Bracing frame 2 can be fixedly mounted on constructure ground or on stage, also can be laid on anyly to have in the plane of some strength temporarily; The height of bracing frame 2 can regulate according to actual installation environment; To meet the installation requirements of varying environment; Bracing frame 2 is directly mated formation above screen body 1, and the two is not rigidly connected, to avoid causing damage because being rigidly connected to shielding body 1.
Preferably, transparent damping pad 8 is provided with, because damping pad 8 is transparent material, so it can't affect the sharpness of display between screen body 1 and protective cover 3, be under pressure to the extruding of screen body 1 by playing buffering because of protective cover 3 simultaneously, a flexible protective is formed to screen body 1; The size of protective cover 3 adapts with the size of each block display unit of screen body 1, and the seamed edge of protective cover 3 has 45 ° of chamferings, and tempered glass protective cover 3 is sealed by clear glass glue with the edge of screen body 1, to reach dust-proof, moistureproof effect.
Preferably, the heat dissipation equipment 4 in the application is blower fan or air conditioner, certainly, also can be other heat dissipation equipment.
Described just in order to the utility model is described above, be construed as the utility model and be not limited to above embodiment, meet the various variants of the utility model thought all within protection domain of the present utility model.
