And each component of Figure 4 is mounted on a configurable board inside the case of the embodiment has a circuit connection relationship.

It looks at the function of each component constituting the above embodiment.

First, the light emitter array 34 is used to display display information as an afterimage, and it is preferable to use a light emitting diode (LED) having a combination of a plurality of light emitters along the longitudinal direction of the main body 32 and having high brightness.

In addition, the display panel 36 displays character information including a setting state, a power state, or a number or letter that the user wants to indicate, and may use an LCD.

The memory 52 stores text information appearing on the display device 30, and the sensor 54 detects a time point at which the moving direction and the moving direction of the display device 30 change according to a user's movement, and detects the detected signal. It provides to the control part 50. In particular, as shown in FIG. 3, the vertical sensor 54a detects a moving direction of the display device 30 as it moves up and down, and the left and right sensors 54b detect movement of the display device 30 in the left and right directions.

In addition, the text editing key 40 included in the input pad 56 may directly input text information to be displayed on the display device 30 or search text information stored in the memory 52 so that the text is desired by the user. It can be used to edit information, and the input content or function selected using the text editing key 40 can be confirmed through the display panel 36.

In addition, since the range adjustment key 42 varies the range in which the display device 30 reciprocates according to the user, the section adjustment key 42 may adjust the image change so that the display information can be displayed correctly by providing the section mode corresponding to the distance difference. .

In addition, the mode conversion key 44 may selectively change the lighting of the light emitting array 34 so that the display information can be correctly displayed according to the change in the moving direction of the display device 30.

For example, when the display device 30 is shaken by selecting the left / right direction of the mode conversion key 44, the display information on the display device 30 appears in the left and right directions, and when the up and down direction is selected, the display information is displayed. Will appear in the vertical direction.

Meanwhile, a method of using the display device 30 including the above-described components will be described.

First, the display device 30 described above is operated when the user turns on the power supply 58, that is, the power switch 46 is turned on.

Thereafter, the user inputs display information stored in the memory 52 using the input pad 56 to check the character information displayed on the display panel 36. In this case, the text information displayed on the display panel 36 is displayed by using an afterimage as an example.

When the display device 30 ready for use is shaken, the sensor 54 operates to sense the moving direction of the display device 30. In this case, the sensor 54 provides a detection signal to the controller 50, and the controller 50 converts the character information into a time-series lighting signal corresponding to the moving direction and provides the light to the light emitter array 34. 34 is lit in time series by the lighting signal. Therefore, the display device 30 displays the corresponding character information as the lighting state is maintained as an afterimage.

First, the input pad 56 may use character information selection, moving section selection, and moving direction selection of display information to be displayed on the display device.

Character information selection includes a direct input method of inputting character information using the character editing key 40 and a selection editing method of editing character information stored in the memory 52.

As an example of the direct input method, when the user wants to display the display information "Please slow down" on the display device 30, the character information stored in the memory 52 is searched through the display panel 36. However, when the character information "Please slow down" is not provided in the memory 52, the user directly inputs display information to be displayed on the display device 30 through the text editor.

An example of the selective editing method is to find the character information stored in the memory 52 through the display panel 36 when the user intends to display the "slow section" on the display device 30. However, when the memory 52 is provided with only the character information "slow", the user may select the character information "slow" and then edit the "slow" through the text editor.

In addition, the user can of course store the character information input by the direct input method and the selective editing method in the memory 52 in the character selection process.

In the movement direction change of the display device 30, when the mode conversion key 44 is selected as the vertical mode and the display device 30 is shaken, the display information displayed on the display device 30 is displayed in the vertical direction Ld. When the mode conversion key 44 is selected as the left and right mode, the display information is displayed in the left and right directions Lc of the display device 30.

On the other hand, the display of the display information for the moving direction is made by the sensor 54, the sensor 54 detects the start point and the end point of the moving direction in which the display device 30 moves and provides the detection signal to the controller 50. do.

The controller 50 applies the time-series lighting signal to the light emitting array 34 to display the display information. The display information of the display information of the display device 30 according to the moving direction is correctly displayed by the above-described series of processes. Will be.

In addition, referring to the display area of the display information displayed on the display device 30 described above, FIG. 7 illustrates a waveform period of a time-series lighting signal for a section in which the display device 30 moves in the left and right directions Lc as shown in FIG. 6A. As shown in FIG. 3, when the display area of the display information displayed on the display device 30 is short, the display area may be reduced by using the section control key 42. This is to reduce the waveform period of the time series lighting signal and to display it on the display device 30.

In addition, when the display area of the display information displayed on the display device 30 is enlarged, the display area section may be enlarged and adjusted using the section control key 42. This extends the waveform period of the time-series lighting signal and displays it on the display device 30.

In addition, although FIG. 7 illustrates a time-series lighting signal according to the movement of the display device 30 in the left and right directions, the time-series lighting signal is also applied to the moving direction in the vertical direction as shown in FIGS. 5A to 5B of the display device 30. Of course, it is possible to adjust the waveform period (not shown).
