It is too small that the display device of multi-screen splicing solves single screen size, watches unclear problem.Multi-screen connected
The display device connect is spliced to form by multiple display, and each display is responsible for showing a part for original picture, such as Fig. 2
Shown in, it is shown that the display device being spliced to form by multiple display 104, it can be seen that display 104 is arranged in array, each
Display is responsible for presenting the 1/9 of original picture, after these equal simultaneous displays of display 104, is also the formation of complete original painting
Face.Generally, the display 104 of the display device of composition multi-screen splicing is exactly the display in general television set (imaging device)
Device, each television set is all made up of three parts, is display, signal processing system and signal translating system respectively.Signal
Processing system is typically directly connected with extraneous signal source, and the primary signal being used for being provided signal source carries out pretreatment, as
The amplification of signal, the optimization of picture quality, the scaling of image, the optimization of clock, de interlacing process, the conversion of color space, inverse
The parsing of journey information resolves, analyzes, judges authority etc. computing.Afterwards, the signal after pretreatment is passed by signal processing system
Giving signal translating system, signal translating system is then responsible for pretreated signal is converted to what display was directly capable of identify that
Electronic signal, and give display by the signal transmission after conversion, final display shows according to the signal after conversion.Make
For the display device of multi-screen splicing, in addition to possessing multiple aforementioned display device, in addition it is also necessary to be configured with signal distribution system, bear
Primary signal is carried out dividing processing by duty, is exactly according to the position of each display briefly by the signal of raw frames, divides
It is slit into the signal of the image that each display is responsible for presenting.It can be seen that the workload of signal processing system is bigger,
And the workload of signal translating system is specifically fixing and smaller.In correlation technique, the display device of multi-screen splicing is in work
The when of making state, each screen is to concentrate to place, when the signal processing system of each display is in duty
Time, the temperature of each display (structure such as the signal processing system of display interior, signal translating system, display screen) is all
Higher, and cut through wind environment the most relatively limited to owing to the arrangement of display is excessively concentrated, cause display device integral heat sink
Rate is relatively low, and then, the holding lasting when display works at high operating temperatures, and this can directly influence these display interior and show
The service life of display screen and imaging precision.
Therefore, in order to ensure that the display device that multi-screen splices can be properly functioning, the heat radiation of the display of overriding concern
Problem.In view of in correlation technique, the display device of multi-screen splicing in working order when, the situation that radiating efficiency is too low,
The embodiment of the present application provides the display device of a kind of novel multi-screen splicing, as it is shown in figure 1, this device includes:
Signal processor 101, signal adapter 103 and display 104；
Signal adapter 103 is positioned on the backboard 108 of display, and the input of signal adapter 103 and display 104
Electrical connection；
Signal processor 101 is separately positioned with signal adapter 103, and signal processor 101 leads to signal adapter 103
Cross cable or optical cable connects.
Wherein, signal processor 101 is the device carrying signal processing system, and signal adapter 103 is carrying
There is the device of signal translating system.The hardware of display 104 is only tied by the display device of multi-screen splicing provided herein
Structure is adjusted, and is not required to the internal circuit to signal processing system and carries out substantial adjustment.
Signal adapter 103 and signal processor 101 are separated and (is primarily referred to as being arranged far from signal processor 101
On the position of display screen) after, signal adapter 103 remains on the backboard 108 being set directly at display, now, and signal
Transmission range between transducer 103 and display 104 is the shortest, the problem that will not bring display signal attenuation.Meanwhile, signal
After processor 101 separates with signal adapter 103, signal processor 101 can be arranged in the cabinet on ground.Correlation technique
In, signal adapter 103 and signal processor 101 are all mounted on the backboard 108 of display, due to the backboard of display
The narrow space of 108 positions, thus i.e. substantially increase big heat sink and be also helpless to the raising of heat dissipation capacity, radiating efficiency.But, will
After signal processor 101 separates with signal adapter 103, signal processor 101 can be arranged on distance signal transducer 103
Remote position, when being arranged far from signal adapter 103 ground such as signal processor 101, signal processor 101
Residing space is no longer influenced by limiting, and the heat that these are carried out from display screen behind small space, it is placed into mark
In quasi-industrial chassises, by reasonably heat radiation and Duct design, it is very easy to realize high density, high efficiency heat radiation environment.And,
Owing to signal adapter 103 caloric value operationally is the least, therefore, the temperature of display screen surrounding space can't be made
Become excessive impact.
As can be seen here, by signal processor 101 and signal adapter 103 are separated, it is ensured that there are enough spaces
Can dispel the heat the signal processor 101 producing high heat, display 104 close to each other and signal adapter 103 are not
Too high heat can be produced so that the temperature of three's location is in relatively low limit value, it is ensured that signal processor
101, signal adapter 103 and display 104 can work long hours under good ambient temperature, especially ensure that imaging
Device, i.e. display 104 can work long hours under good ambient temperature.And then improve the display dress of multi-screen splicing
Put service life and the imaging precision of entirety.
Wherein, signal processor 101 is preferably connected by fiber optic cables with signal adapter 103.It practice, signal processing
The connection cable 102 of device 101 and signal adapter 103 can have multiple, as netting twine (concrete such as category-5 cable, surpass five classes
Line, six class lines etc.), BNC cable etc..But consider use scene, it should use fiber optic cables to connect at signal
Reason device 101 and signal adapter 103.The mainly display device of multi-screen splicing is usually located at higher position (floor in full
High position), and display device provided herein is signal processor 101 and signal adapter 103 is separated sets
Put mode, therefore, each display 104 (signal adapter 103 being primarily referred to as on display 104) and signal processor 101
Apart from each other.Owing to each display 104 all has the signal source of its correspondence, and, these signal sources all pass through signal transmssion line
Carrying out the transmission of signal, therefore the data volume of the required transmission of signal transmssion line is the biggest, and category-5 cable and CAT5E UTP cable are difficult to
Reaching high speed, high-quality signal transmission requirement, in order to reach request signal transmission, then need to increase multiple cable, this can cause
System realizes difficulty to be increased, and then causes overall security to reduce.Although six class lines ensure that volume of transmitted data, but cost mistake
High.Under this kind of environment (distance between signal processor 101 and signal adapter 103 is bigger), effective transmission of BNC cable
Distance is subject matter, and it ensure that the transmission range of 70 meters, but for the display device of multi-screen splicing, 70 meters
Distance is to be difficult to ensure that signal processor 101 can be connected with farthest signal adapter 103.Therefore considered and made
By scene, it should select glass fiber cables to connect signal adapter 103 and signal processor 101.
The display device of multi-screen splicing is (to be included signal processor 101, signal adapter by multiple presentation device simultaneously
103 and display 104) constituted, the signal processor 101 in these multiple presentation device can unify to be arranged on a cabinet
In, so it is easy to management.(such as the machine at host computer when these multiple signal processors 101 are positioned in same cabinet when
Case has from top to bottom set gradually multiple signal processor 101), fan+heat radiation patch can be set in cabinet inside increase
Radiator structure, it is also possible to use the radiator structure of semiconductor heat-dissipating patch+water cooler to dispel the heat enclosure interior, to ensure
The temperature of cabinet inside is in rational limit value.
Wherein, signal adapter 103 includes: signaling conversion circuit and the protection shell 114 of parcel signaling conversion circuit；
The input of signaling conversion circuit is connected by cable 102 with signal processor 101, the output of signaling conversion circuit
End electrically connects with the input of display 104.
Protection shell 114 is usually metal material, it is possible to increase the rate of heat dissipation of signaling conversion circuit on its interior.And
And the signaling conversion circuit of its inside can be played a protective role by arranging protection shell 114.Protect on shell 114 permissible
It is provided with interface, is used for the input connecting signaling conversion circuit and signal processor 101.Can also is that at protection shell 114
On offer a notch, allow the cable connecting the outfan of signaling conversion circuit and the input of display screen pass through.Outside protection
Shell 114 can be arranged on the backboard 108 of display, it is also possible to is the backboard 108 pressing close to display, but is not secured to display
On the backboard 108 of device.The outer surface of protection shell 114 can arrange cushion pad, to prevent when shell 114 is protected in handling
Waiting, protection shell 114 comes off and makes the signaling conversion circuit inside it suffer damage.
Concrete, protect the shell 114 hollow cavity in one end open, and protect opening and the display of shell 114
Backboard 108 fit so that the backboard 108 of protection shell 114 and display forms closed space, signaling conversion circuit is positioned at and closes
Close the inside in space.
Such as Fig. 3, as shown in 4 and 5, protection shell 114 can be arranged to the shape such as the cube of hollow, prism-shaped body.Protection
Shell 114 is to be directly anchored on the backboard 108 of display.When signal adapter 103 goes wrong when, can be direct
Protection shell 114 is disassembled, then signal adapter 103 is carried out maintenance.
Display screen can normally work, and except needing to get the signal of display, is also carried out it by outside power supply
Power supply.Accordingly, it would be desirable to protection shell 114 to be divided into two parts, it is electric energy distribution district 109 and signal switch region 113 respectively.Tool
Body, protection shell 114 includes electric energy distribution district 109 and signal switch region 113；
The lower surface in electric energy distribution district 109 is provided with two power interfaces 111, and two power interfaces 111 are by being positioned at guarantor
Protect the adapter electrical connection within shell 114.Now, such as Fig. 3, as shown in 4 and 5, electric energy distribution district 109 is positioned at left part, signal
Switch region 113 is positioned at right part, and certainly, signaling conversion circuit is in signal switch region 113.
The display device of multi-screen splicing provided herein, carrying out electric energy supply when, is not to use by one
The mode that individual main power is powered to each display 104 respectively, but use the mode transmitting electric energy successively.Concrete and
Speech, main power connects first power interface of first display by cable, and first power supply of first display connects
Mouth will be powered, owing to two power interfaces of first display pass through to parts such as the display screens of first display
Being positioned at the adapter electrical connection of protection enclosure, therefore, first power interface of first display is showing to first
While showing that the display screen of device is powered, being transferred out by electric energy also by second power supply interface, this second power supply connects
Mouth is connected with first power interface of next display, and then is powered to next display.And then use this
The mode that electric energy transmits successively is that each display is powered, and optimizes the distribution of circuit.
Although signaling conversion circuit operationally produced heat is relatively low, but the part of electric energy supply also needs to display screen
Light source part is powered and current value is compared with big (more much larger than the current value of signal transmission), and therefore, in actual use, electric energy distributes
The caloric value in district 109 is bigger than the caloric value of signal switch region 113, in order to ensure that the temperature in electric energy distribution district 109 will not surpass
The temperature crossing signal switch region 113 is too many, and fin 110 is the most preferably arranged on the outer surface in electric energy distribution district 109, and
Two interregional increase perforates, to intercept the too much conduction of the heat in power distribution district to signal switch region 113.On the other hand,
The heat generating spot that radiator plays power distribution district excessively concentrates scatter, to guarantee that human body can not caused by casing outer surface
The high temperature of injury.

District 113 heat generation rate operationally can calculate, and the unit rate of heat dissipation of the fin of certain material, model is also
It is available, therefore, by comparative unit rate of heat dissipation and heat generation rate, just can calculate and should use that how many units are (face
Long-pending) fin 110.Concrete, fin 110 can use copper and aluminum alloy material.As shown in Figure 2, fin
The surface of 110 could be arranged to rough form, and then increases the contact area of fin 110 and air, improves heat radiation
Rate.
In order to improve the fixing intensity of protection shell 114, fixing structure can be increased in the surrounding of protection shell 114.
It is respectively arranged with the first fixed lobe 105 and the second fixed lobe on the upper side wall of protection shell 114 and lower wall
106, the first fixed lobe 105 and the first fixed lobe 105 backboard 108 with display respectively is connected by screw；
First fixed lobe 105 and the second fixed lobe 106 are respectively in different gravity verticaies.
First explaining gravity vertical, gravity vertical is the center of gravity line with the earth's core of object, it is possible to use plumb line is surveyed
?.Front view under use state shown in Fig. 3, the gravity vertical in figure is vertical with the upper edge of protection shell 114.
First fixed lobe 105 and the second fixed lobe 106 can be respectively by fixing screw and protection shell
114 are attached, and the two mainly plays the effect of fixed position, play the effect supporting protection shell 114, when the two is solid
Determine projection be positioned at same gravity vertical (dotted line in Fig. 3 is just a gravity vertical) upper when, protection shell 114 may phase
Backboard 108 for display shakes, and that namely fixes is the most firm.And when the dislocation of the two fixed lobe (is not total to
Gravity vertical) when, just improve fixing stability, the backboard 108 making protection shell 114 be difficult to display produces relative
Displacement.
Except arranging fixed lobe to play fixation in the both sides up and down of protection shell 114, it is also possible to outside protection
The left and right sides of shell 114 arranges spacing fixed structure, to ensure that protection shell 114 will not shake.Concrete, protecting
The left and right sides protecting shell 114 is also respectively provided with the 3rd fixed lobe of the backboard 108 connecting protection shell 114 and display
With the 4th fixed lobe；
3rd fixed lobe and the 4th fixed lobe are positioned on same horizontal plane.
4 convex roles: one, 2 two projection slip-off preventing, tool-free screws realize, can not when safeguarding at the scene
Need the most detachable lower protection shell 114 of use instrument and internal circuit unit；Three and four use pin designs, effect be
When in-site installation containment vessel and internal circuit unit, as auxiliary positioning pin, make the adapter on containment vessel with aobvious easily
The correct para-position of adapter in display screen patches.This designs at two, in addition in view of link fixation, is more in order at existing
The design that field is easy to maintenance and is formed.
Except arranging fin 110, it is also possible to by the way of arranging louvre, improve radiating efficiency further, specifically
, the protection shell 114 side away from display 104 is provided with the first louvre 107.
Can also is that and the fit system of fin 110 and louvre is adjusted, i.e. fin 110 is multiple and many
Being arranged on the containment vessel side away from display 104 of individual fin 110 interval；
First louvre 107 is multiple, and is arranged in array-like at the interval between adjacent two fin 110.
Further, the seam of electronic device easily produces bigger heat, therefore, it should dispel the heat these positions
Process, i.e. the lower surface of signal switch region 113 is provided with signal input 112, and the perimembranous of signal input 112 is surrounded with many
Individual second louvre.
The environment that louvre is suitable for air flow rate is higher uses；Compared to louvre, fin 110 is more suitable at sky
The environment that the air-flow general character is poor uses.Owing to the use environment of the display device of multi-screen splicing is difficult to predict in advance, therefore,
Radiating efficiency can be ensured in the way of using fin 110 and louvre combination appearance.
Can also is that after being provided with a large amount of louvre on protection shell 114, arrange in the edge of protection shell 114
Draw-in groove, and the card-tight part 120 that matches with draw-in groove is set at the edge placement of fin 110 so that card-tight part 120 can be with card

Preferably, as shown in Fig. 7 (Fig. 7 is the partial enlarged drawing of bottom left section structure in Fig. 6), cable clamping interface 116 is for arranging
Opening on the side frame 118 of fixed mount 115, and opening part is provided with the first baffle plate, so that this opening forms semi-closed state.
After cable arranges and snaps in opening, the first baffle plate can block cable, so that cable will not remove from opening.
Concrete, as shown in FIG. 8 and 9, wire lead slot 117 can arrange multiple card-tight part 120, multiple card-tight part 120 edges
The length direction of wire lead slot 117, is arranged on the inside of wire lead slot 117.The cross section of wire lead slot 117 (is perpendicular to wire lead slot 117 long
The cross section in degree direction) U-shaped, card-tight part 120 is just provided on the inwall of U-shaped wire lead slot 117.More specifically, clamping
Portion 120 can be in vertical rod-like structure, and card-tight part 120 is vertical with the sidewall of U-shaped wire lead slot 117.And clamping
Portion 120 can be arranged to bascule, i.e. card-tight part 120 and can move to vertical direction with the sidewall of wire lead slot 117 along it, with
Make card-tight part 120 move into wire lead slot 117 internal, and (Fig. 8 and Fig. 9 is shown respectively to make card-tight part 120 remove wire lead slot 117 inside
The card-tight part 120 two kinds of location status before and after movement).In order to enable the position of card-tight part 120 to fix, mainly at it
After moving into U-shaped wire lead slot 117 inside, position will not arbitrarily change and (if its position changes, then be difficult to play card
Live the effect of cable), therefore, stop interface also should be set or reply structure, to ensure the phase of the position of card-tight part 120
To stable.Wherein, barrier structure can be provided in multiple levers of shaft-like card-tight part 120 perimembranous, and multiple levers are along clamping
The length direction in portion 120 sets gradually, and can be blocked lever by the sidewall of wire lead slot 117, and then be seized card-tight part during use
120, make the position of card-tight part 120 be relatively fixed.Replying structure can be such as spring 121, as shown in Figure 10, now, and card-tight part 120
Being positioned at the one end within wire lead slot 117 and should be provided with second baffle 119, spring 121 is positioned at second baffle 119 and wire lead slot
Between the sidewall of 117, during use, being acted on by spring 121 elastic force, second baffle 119 can be only by spring 121 elastic force effect
Under (be primarily referred to as user do not pull card-tight part 120 when), the major part of card-tight part 120 can be moved to wire lead slot
The inside of 117, is that card-tight part 120 plays the effect blocking cable.
