Referring to FIG. 5, as mentioned in FIG. 2, when the police indicator rod 14 is moved at a predetermined speed, a predetermined pressure applied to the police indicator rod 14 is used as the first external control signal, and is shown in FIG. Since the selected color selection buttons, that is, the red, green, and blue buttons 21, 22, and 23 are selected, the input external control signal is divided into a second external control signal, and the color selector 24 is connected to the color selection button. The second external control signal input terminal (not shown) and the light emitter driver 13 are configured to output a control signal for a color selected according to the second external control signal input by the light emitter driver 13.

The operation of the present invention having the configuration as described above is as follows.

As shown in FIG. 3B, a second external control signal corresponding to a button directly selected by the user among the color selection buttons is input to the color selection unit 24. The color selector 24 is driven by the third control signal in the high state output from the start logic unit 6 to output a predetermined voltage corresponding to the input second external control signal to the light emitter driver 13 to output the corresponding light emitter. That is, it is driven to output the light signal of the color selected from the LED.

Here, the light emitter 20, that is, the LED is preferably configured using a three-color LED that outputs the light signal of different colors according to the magnitude of the predetermined voltage.

For example, as shown in FIG. 6, the anode terminal of the red LED ⓑ is connected to the first terminal ⓐ, and the anode terminal of the green LED ⓓ is connected to the second terminal ⓒ. The three-terminal ⓔ may be a three-color LED having a structure in which the cathode terminals of the red and green LEDs ⓑ and ⓓ are connected in common. At this time, when the three-color LED is operated, when a constant voltage is applied to the first terminal ⓐ and the second and third terminals ⓒ and ⓔ are grounded, the three-color LED emits red light and the first and second terminals ( When ⓐ and ⓒ are grounded and a constant voltage is applied to the third terminal ⓔ, the tricolor LED emits green light, applies a constant voltage to the first and third terminals ⓐ and ⓔ, and connects the second terminal ⓒ. When grounded, the tricolor LEDs emit yellow light that combines red and green.

In addition, as another example of the three-color LED, the first LED outputs a red light signal when a voltage of 5 volts [V] is applied, and the second LED outputs a green light signal when a voltage of 4 volts [V] is applied; When the voltage of 3 volts [V] is applied, the third LED outputting the blue light signal is integrally formed, and when the second external control signal is a control signal corresponding to red, the color selector 24 is 5 volts. The voltage of [V] may be configured to be output to the light emitting driver 13.

Meanwhile, in the present invention, the stop button 18 shown in FIG. 3B is configured to interlock with the red button 21 of the color selection buttons, and the passing button 19 is the blue button 23 of the color selection buttons. It can also be configured to work with. In this case, since the switch interlocked between the stop button 18 and the red button, and the switch interlocked between the pass button 19 and the blue button 23 is a known technique, a separate description is omitted. In addition, assuming that normal character information is displayed when the police indicator rod 14 is moved in a predetermined direction, when moving in the reverse direction, the control and memory unit 12 outputs the data of the stored character information in reverse order. Even if the indicator rod 14 is randomly moved in the forward or reverse direction, constant character information may be always displayed.

7 is a schematic block diagram showing another embodiment of the display device using the afterimage effect according to the present invention.

Referring to FIG. 7, the power supply 25 is simultaneously connected to each part of the switch and the system to supply a predetermined voltage to each part of the system when the user turns on the switch (not shown). The frequency oscillator 26 is configured to be driven by a predetermined voltage applied from the power supply unit 25 to oscillate a frequency of a predetermined size and output the oscillated predetermined frequency to the clock generator 27, and the clock generator ( 27 is driven by receiving a predetermined voltage from the power supply unit 25 and receives a predetermined frequency oscillated by the frequency oscillator 26 to generate a clock signal corresponding to the oscillation frequency to control and generate a clock signal. 28).

The control and memory unit 28 is driven by receiving a predetermined voltage from the power supply unit 25 to the outside of data such as shapes and characters of various articles already stored according to the clock signal applied from the clock generator 27. The JxK bits of data selected by the applied control signal are sequentially outputted to the light emitter driver 29 by K bits, and the drive controller 30 is controlled. The light emitter driver 29 is configured at the front of the LED to drive the LED using the J × K bits of data applied from the control and memory unit 28.

On the other hand, the drive control unit 30 is configured at the front end of the motor to be driven by a control signal applied from the control and memory unit 28 to rotate the motor in a forward or reverse direction at a predetermined speed.

A display apparatus using the afterimage effect having the above-described configuration will be described with reference to FIG. 8 as follows.

When the user turns on the main switch of the advertisement display device, the control signal generated from the switch is applied to the power supply unit 25 to drive the power supply unit 25. When the power supply unit 25 is driven, the constant voltage Vcc generated from the power supply unit 25 is supplied to each system unit to operate a component of each system unit.

The frequency oscillator 26, which receives the constant voltage Vcc from the power supply 25, is driven to oscillate and set the predetermined frequency to output the oscillated predetermined frequency to the clock generator 27. The clock generator 27 is driven by receiving a constant voltage Vcc from the power supply 25 to generate a clock signal corresponding to a predetermined frequency applied from the frequency oscillator 26 to control and generate a clock signal. 28). The control and memory unit 28 is driven by receiving a constant voltage Vcc from the power supply unit 25 to detect data corresponding to a control signal input by an external user, and generate the corresponding data in the clock generator 27. The data is temporarily stored in a built-in buffer or the like on the clock signal, and sequentially outputs the selected JxK bits of data to the light emitter driver 29 sequentially by K bits. The light emitter driver 29 selectively drives the corresponding LED using the K bits of data applied from the control and memory unit 289.

On the other hand, the control and memory unit 28 outputs a predetermined control signal to the drive control unit 30 to control the drive control unit 30, the drive control unit 30 to the control signal applied from the control and memory unit 28 Accordingly, the driving of the driving body (here, the motor is described as an example) is controlled.

Here, K is data about the number of LEDs mounted in the one-dimensional display device inserted into the display device for advertising, J is data about the number of flashes of each LED according to the distance traveled by the one-dimensional display device In other words, it can be seen that the control signal output from the control and memory unit 28 to the drive control unit 30 is data on the amount of motor rotation proportional to the number of J bits. In addition, if the letter and the article shape are displayed while the motor is rotated in the forward direction, and the motor is moved to the end in the forward direction and then moved in the reverse direction again, the control and memory unit 28 stores the stored article form as described above. Alternatively, the data of the character information is output in the reverse order, so that it is possible to always display a certain steady state article form and character information.

Finally, another embodiment of the display apparatus using the afterimage effect according to the present invention will be described with reference to FIG.

After delaying by an L period through the delay unit 34, the L light emitting unit 35 is sequentially outputted (L-1) J + 1 to LJ times by K bits.

In addition, the control and memory unit 28 outputs a control signal having the same period as the above-described first light emitting unit 31 to the first driving controller 36 to drive the motor in synchronization with the first light emitting unit 31. The control signal applied from the control and memory unit 28 through the one cycle delay unit 37 is delayed by one cycle equal to the one cycle delay unit 32 described above, and then the second drive control unit 38 is delayed. Outputs and drives the motor in synchronization with the second light emitting device driver 33, and repeats this L times, thereby delaying the L cycle delayed by the control signal applied from the control unit and the memory unit 28 through the L cycle delay unit 39. It is configured to drive the motor in synchronization with the L-light-emitting body driving unit 35 by delaying the L period by the same period as the machine 34 and outputting the L driving unit 40.

After a delay of one cycle through 32), it is outputted to the second light emitting device driver 33. The above-described process is repeated L times to delay L cycles of LJ × bit data through the L cycle delay unit 34, and then It outputs to the L light-emitting driving unit 35.

Each of the light emitter drivers 31, 33, 35 selectively drives the corresponding LED group as shown in FIG. 10 by using the K-bit data applied from the control and memory unit 28. FIG.
