Moveable intelligent LED television can be connected with computer, smart mobile phone, panel computer and other electronic equipment, and synchronously plays arbitrary content, and play content can be stored in automatic cycle broadcasting in system, without the need to connecting external device.
Solve the irremovable problem of indoor LED television, can adjust flexibly along with the needs of user and the position of putting.
Thermal diffusivity is good, easy to maintenance.LED television is by device separates such as LED display, TV box, sound equipments, and as in maintenance process, only need break problematic part, can not impact other parts;
LED intelligent TV set realizes being interconnected by wired and wireless mode with PC, panel computer, other mobile terminals, strengthens Consumer's Experience function.
Mobile LED intelligent TV set, screen image quality is gorgeous, and brightness is high, visual angle is wide, TV screen has seamless spliced, modularization maintenance, color natural reality, show uniformity are better, the advantages such as color gamut space is wider, can substitute most of Projection Display, city's scene is very wide.

Embodiment
Below in conjunction with Figure of description, the utility model is described in detail, but it should be noted that enforcement of the present utility model is not limited to following execution mode.
See Fig. 1-Figure 17, a kind of moveable intelligent LED television, comprises body 5, sound equipment 3, TV box 9, castor 1, base 2, is provided with sound equipment 3 bottom body 5, body 5 is connected with TV box 9 by signal netting twine 8, be fixed with base 2 bottom sound equipment 3, be fixed with castor 1 bottom base 2, body 5 back side is encapsulated by three bonnets 6 arranged side by side, body 5 back is provided with interface 7, TV box 9 is connected with interface 7 by signal netting twine 8, is provided with interlayer 4, for storing articles between sound equipment 3.
Be provided with P2.5LED in body 5 and show module, data acquisition sending card, video processor, data receiver card; P2.5LED shows module and is powered by Switching Power Supply, P2.5LED is shown module and is connected with data receiver card by signal line, data acquisition sending card is connected with data receiver card, video processor, video processor is connected with video camera, TV box 9, DVD player, data acquisition sending card surpasses five class netting twines by 8 cores and is connected with computer, data acquisition sending card is by GPRS module or mobile communication, and data acquisition sending card also can be communicated by wifi with panel computer.
The current conversion of AC220V can be that P2.5LED shows module and the spendable DC5V power supply of miscellaneous part by Switching Power Supply, data acquisition sending card receives the broadcast information of the equipment such as mobile phone, network, video camera, DVD player, panel computer, TV box 9, and determine that P2.5LED shows the information such as Show Color, displaying time, not displaying time of module, then data receiver card is transferred to, data receiver card triggers P2.5LED through signal line and shows module, drives display image by constant-current drive circuit.
Wherein, P2.5LED shows module and is rearranged by module group unit, sees Fig. 4, laterally 15 row module group units, longitudinally 8 row's module group units, and long nearly 2.6 meters of common composition, the display screen of wide 1.5 meters, module group unit is driven by the constant-current drive circuit of blue, green, red chipset.
The triggering of constant-current drive circuit is completed by 74HC245,74HC245 ternary output, eight road signal transmitting and receivings, and from the data that main control end exports, clock, latch, enable signal cushions through 74HC245, and amplification gives the constant current of each road to reach driving object respectively.The row exported from main control end selects signal to cushion through 74HC245, and the reverser doing cascade to after amplifying three or eight decoders and auxiliary three or eight decodings reaches driving object.
See Figure 10, HUB7516PIN interface, input and output two groups of data and clock, latch, enable control end, three or eight decode lines select signal ABC cascade row to select signal D, E (E does oppositely).
See Figure 11, LED face matrix array, network implication is that each B* represents 32 row 1 and arranges row power supply on the encapsulation of three-in-one SMD lamp and the constant current drive IC of correspondence thereof and MOS switching tube, and H* is the row power supply of corresponding different rows.
See Figure 12, decoupling capacitor combine, decoupling capacitor effectively can reduce signal and the constant current of responsible difference in functionality and being coupled of logic IC, according to drive IC specifications shownschematically the usual value of IC level range be 0.1uF or 1uF.
See Figure 13, electrochemical capacitor combines, and primary responsibility carries out filtering effect to the ripple that power supply exports.Usual value 220uF and 470uF, the withstand voltage big current 60A small voltage 5V that should follow inputs standard.Usual specification is 16V.
See Figure 14-Figure 17, data message can be sent to the wireless Internet of Things of GPRS by GPRS module, and remote monitoring center is by IP address acquisition data message.
