Embodiment

As shown in Figure 1, put single display device except casing is arranged from environment-friendly electronic of the present utility model, its circuit part comprises: circuit board section II, the LCDs I that links to each other with circuit board section II, and the wire communication socket III of connecting circuit plate portion and external host.The formation of described circuit board section II and other parts is: microprocessor 1 links together with memory circuit 2, the key groups 3 that is installed on the casing respectively, microprocessor 1 is according to the input condition of key groups 3, handle, corresponding the single content of point delivered to memory circuit 2 and LCDs I.In conjunction with shown in Figure 9, from its housing face-plate front elevation as can be seen, this is put single board and adopts the portable super-thin design, its main part is a LCDs I, be provided with key groups 3 below the LCDs I, include three button K1, K2, K3, execution " making progress ", " downwards " reach " calling " function respectively, for consumer's usefulness.Wireless transmitter module IV is a selectable unit.

In conjunction with as Fig. 2-Fig. 7, further the utility model electronics is put the circuit theory diagrams of single display device various piece.The circuit theory diagrams of forming microprocessor (CPU) unit 1 by EM78P447 shown in Figure 2, wherein, the P6 mouth of microprocessor U1 meets LCDs I (LCM) (as shown in Figure 6), P71-P73 in the P7 mouth meets storer U2 (as shown in Figure 3), P50-P52 in the P5 mouth meets key groups K1, K2, K3 (as shown in Figure 4) respectively, in addition, also (chip U3's P5 mouth as shown in Figure 7) links to each other with wired communication interface III (as shown in Figure 5) and wireless transmitter module IV.

Below in conjunction with Fig. 9, introduce the principle of work and the course of work that the utility model is put single board in detail.

After energized, microprocessor U1 electrification reset, carry out initialization (frame 100) and begin to enter duty, and judge whether to communicate (frame 101) with main frame, then carrying out frame 102 as needs communicates by letter with main frame foundation, carry out data transmission, as not needing communication then to enter the key scan state, three button input ports of P50-P52 are scanned, judged whether that button presses (frame 103), supposed not have button then to call delay procedure (frame 104), do not pressed if in continuous 30 seconds, all have button by microprocessor U1, then close LCDs I, enter power down mode.

Suppose to have button to press, then be determined further, the identification button.At first, judge whether to be " making progress " key (frame 105), the key that " makes progress " in this way, the consumer's that rolls some list content shows that a some single-character given name claims or numbers, if arrived first, then stops menu rolling (frame 106); Then enter next step if not " making progress " key and judge whether to be " downwards " key (frame 107), if " downwards " key, then roll consumer's some list content, the next point of demonstration single-character given name claims or numbers, if arrived last, then stop menu rolling (frame 108), then judge whether to be " calling " key (frame 109) entering next step button if not " downwards " key, if, then send enabling signal to wireless transmit chip U3 by microprocessor U1, start radiating circuit, launch the call service instruction, and limit the time interval of calling out next time, promptly will could launch this call instruction, to reach the purpose of saving battery every certain hour.

In sum, the consumer if the wire communication socket III that the utility model is put single display device at a Dan Ze is inserted on the corresponding interface, carries out data transmission with main frame in the process of consumption, consult menu and carry out a single operation; After point singly finished, microcontroller circuit 1 in memory circuit 2, simultaneously, also showed with these content delivery the content stores of institute's menu to LCDs I; Can also select to consult in institute's menu perhaps call service by the button in the key groups 3.
