[background technology]
Research and development success along with twentieth century blue light and green-light source, led light source substitutes traditional visible light source gradually, utilize led light source to make large flat display screen (FDP) and become possibility, lattice module or pixel cell that it utilizes light emitting diode to constitute are formed the large tracts of land display screen, be subjected to people's favor, power consumption is low, response speed is fast, operating ambient temperature range is wide as working, full firmware equipment volume is little, anti-impact force reaches life-span length etc. well; Simultaneously itself be semiconductor element, thus can be compatible fully with the IC circuit, and control and driving circuit are easy of integration in flat-panel monitor, further reduce the volume of display, also can conveniently realize the multipath transmission of signal.
At present, no matter monochromatic LED display screen on the market is that scan mode or static mode are all many because of the device that is provided with, can't layout and be designed to double plate structure, and there is following shortcoming in single lamp LED display that double plate structure forms: two plate overlaying structures, if peg graft, easily loosening, reliability is not high; If weldering is dead, almost method is keeped in repair; Single lamp brightness is not enough, can not reach the requirement that shows under high light.Therefore, the display screen of this class formation, not only volume is big, the cost height, brightness is not enough, gives and produces, keeps in repair and all brought inconvenience.
[utility model content]
The utility model purpose is to solve the above problems, and a kind of LED display of high brightness of reasonable in design, dependable performance is provided.
The LED display of a kind of high brightness of the utility model, comprise LED display main body, LED lamp holder, be located at the control circuit board in the housing, described control circuit board is a single plate structure, its control circuit is divided into four layers, its upper and lower two-layer be the control circuit routing cell, middle two-layer power-supply wiring unit and the cloth ground wire unit of being respectively; The control circuit routing cell is provided with scan control unit, indicative control unit and central processing unit, the vision signal that described central processing unit sends exports the scan control unit to through asynchronous control circuit, the scan control unit transfers to indicative control unit, described LED lamp holder evenly is arranged on the control circuit routing cell, its lead-in wire passes circuit board, is welded on another control circuit routing cell.
Preferably, the LED lamp holder is at least a LED luminotron formation.
Described scan control unit is connected in series successively with more than one indicative control unit.
Described asynchronous control circuit is connected with the indicative control unit circuit with one group of above scan control unit.
The LED display of the utility model high brightness, described control circuit board are single plate structure, and its control circuit is divided into four layers, its upper and lower two-layer be the control circuit routing cell, middle two-layer power-supply wiring unit and the cloth ground wire unit of being respectively; The control circuit routing cell is provided with scan control unit, indicative control unit and central processing unit, the vision signal that described central processing unit sends exports the scan control unit to through asynchronous control circuit, the scan control unit transfers to indicative control unit, described LED lamp holder evenly is arranged on the control circuit routing cell, its lead-in wire passes circuit board, is welded on another control circuit routing cell.The display screen that makes like this have high brightness, wide vision, long service life, in light weight, modular construction, easy for installation, be easy to characteristics such as maintenance.

[embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Be to be understood that concrete embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Shown in ginseng Fig. 1,2 and 3, high-brightness LED display screen of the present utility model, be by comprising that LED display main body 1 and the control circuit board of being located in the housing 23 constitute, described control circuit board 3 is a single plate structure, its control circuit is divided into four layers, its upper and lower two-layer be the control circuit routing cell, middle two-layer power-supply wiring unit and the cloth ground wire unit of being respectively; On control circuit board 3, be provided with signaling interface 4 and power interface 5.LED lamp holder 6 evenly is arranged on the control circuit routing cell 7, and its lead-in wire passes circuit board, is welded on another control circuit routing cell.
In addition described LED lamp holder 6 be can two LED luminotron formation, help increasing brightness.
Further, described control circuit routing cell 7 is provided with scan control unit 10 and indicative control unit 11, the vision signal that central processing unit 8 sends exports scan control unit 10 to through asynchronous control circuit 9, and scan control unit 10 is connected in series successively with more than one indicative control unit 11.
Asynchronous control system circuit 9 can receive and store the vision signal from computing machine, control displaying contents and display mode.Driver is controlled with single chip microcomputer, the multiple font of built-in international character library.Be provided with down move, move left and right, horizontal open vertically open, waterfall shows, multiple control modes such as switching fast.Adopt large scale integrated circuit and field programmable gate array, level of integrated system is high, and control function is strengthened greatly, and reliability, dirigibility improve greatly
