Three, summary of the invention:

The purpose of this utility model provide a kind of can not only display message, and can see the perspective LED display device of the object of LED printed board back clearly.

Concrete scheme of the present utility model is: a kind of perspective LED display device, comprise LED, LED printed board, outer installation frame, it is characterized in that: 2 or 2 above LEDs are installed in the long limit of strip LED printed board at interval, the light emission direction of LED is parallel to the LED printed board, LED printed board spaced and parallel more than 2 or 2 is installed in the outer installation frame, is connected in series by the led board circuit between the LED printed board more than 2 or 2.

This programme is by installing LED at interval on the long limit of strip LED printed board, strip LED printed board spaced and parallel is installed in the outer installation frame, between adjacent like this LED and the adjacent LED printed board slit is arranged all, just can see the object of LED luminotron back by the slit.

Adopt the beneficial effect of such scheme to be: can know the object of seeing LED printed board back, make the object of LED printed board content displayed and back corresponding, better effects if, and also easy for installation, simple in structure.

Five, embodiment:

From Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 is as can be known: the utility model is mainly by LED 1, LED printed board 2, outer installation frame 7, the led board circuit constitutes, wherein the led board circuit is by input interface 3, DCU data control unit 4, led circuit unit 5, output interface 6 constitutes, it is characterized in that: the above LED 1 of 2 or 2 is installed in the long limit of strip LED printed board 2 at interval, the light emission direction of LED 1 is parallel to LED printed board 2, LED printed board 2 spaced and parallel more than 2 or 2 are installed in the outer installation frame 7, are connected in series by the led board circuit between the LED printed board 2 more than 2 or 2.It is the optimum arrangementing mode of LED in the utility model that the arc end of LED stretches out outside the LED printed board 2.

From Fig. 4, Fig. 5 as can be known: the led board circuit is made of input interface 3, DCU data control unit 4, led circuit unit 5, output interface 6, wherein input interface 3 is sent to DCU data control unit 4 from the computing machine acknowledge(ment) signal, DCU data control unit 4 sends instructions to led circuit unit 5, and the signal that input interface 3 sends directly is transferred to the input interface of next LED printed board from output interface 6.

As can be seen from Figure 5: led circuit unit 5 is made of shift register, LED, wherein the Q1-Q7 pin of shift register is connected to the negative pole of LED respectively, the positive pole of LED is connected to power supply, and the Q7 of shift register is connected with the serial data mouth SER of adjacent shift register.Always have 8 shift registers in Fig. 5,64 LEDs are divided into two groups, and each organizes 4 shift registers, 32 LEDs.Every group of shift register is connected with serial data line, data zero clearing line, data latching line, brilliance control line respectively.

From Fig. 5 also as can be known: the serial data line the DCU data control unit 4 connects the serial data mouth SER of shift register by triode Q1; Data zero clearing line in the DCU data control unit 4 is by triode Q2 and meet the data clear terminal SRCLKL of all shift registers; Data latching line in the DCU data control unit 4 is by triode Q3 and meet the data latching end RCLK of all shift registers; Brilliance control line in the DCU data control unit 4 is by triode Q4 and meet the Enable Pin E of all shift registers.

From Fig. 3, Fig. 5 also as can be known: input interface 3 adopts interface JP1 the led board circuit, output interface 6 adopts interface JP2 in the led board circuit, interface JP1 and interface JP2 lay respectively at LED printed board 2 two ends, and LED printed board 2 is connected in series by interface JP1, interface JP2 and adjacent LED printed board respectively.

Principle of work of the present utility model is: polylith LED printed board 2 is sleeved on outer installation frame 3, the input interface of the LED printed board that the output interface 6 of the led board circuit of LED printed board 2 is adjacent is together in series, computing machine is with input interface 3 JP1s of data delivery to the led board circuit, wherein serial data line takies a mouth line, the data zero clearing takies a mouth line, data latching takies a mouth line, brilliance control takies a mouth line, when this four road signal wire is sent to led board circuit inlet, being provided with four transistor Q1-Q4 in the porch once drives signal, serial data outputs to the serial data inlet SER of Q1 through the emitter of Q1, the data of accepting when the U1 shift register surpass 8 just backward a carry to U2 shift register serial data inlet SER, the data of accepting when the U2 shift register surpass 8 just backward a carry to U3 shift register serial data inlet SER, so go down, data with U1-U16 have been linked to be together like this, after being totally lost, all data provide the data latching instruction by computing machine again, such sets of data will be on the LED luminotron with bright or do not work and show, brilliance control is divided into the brilliance control of many groups to adapt to various application places.When polylith LED printed board shows composition rectangle picture and text, the data transfer path of the led board circuit of each LED printed board is the same, and normally, the distance of transmission is unlimited, so the graph text information of this perspective LED display device should be many, display graphics also is changeable.
