[Example]

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing an electronic blackboard system according to an embodiment of the present invention.

Referring to FIG. 1, the electronic blackboard system 1000 is an electronic pen 100 when the electronic pen 100 is touched to show a shape, which is referred to collectively as a letter, a symbol, a picture, or a figure, on a transparent panel. After reading the coordinate value of the touch to generate the display signal by reading the operation pattern according to the touch, and the display signal to the external display through the transparent panel, the electronic pen 100, the camera sensor unit ( 200, a control unit 300, a flat panel display device 400, and a transparent panel 500.

First, the electronic pen 100 attempts to approach the shape on a transparent panel made of tempered glass or a similar transparent glass using a nib attached to a part, so that the nib of the electronic pen 100 is transparent panel. A display signal is generated by reading an operation pattern according to a touch on some surface of the upper portion.

The transparent panel of the present invention may be made of a tempered glass material or a glass material similar thereto, but may be made of any one of plastic thin film glass, plywood glass, acrylic plastic material, and polycarbon plastic material. In addition, the nib of the electronic pen 100 may be manufactured with one selected from hard plastic, metal, and ceramic materials.

The camera sensor unit 200 recognizes the coordinate values of the electronic pen 100 when the electronic pen 100 approaches the transparent panel.

The camera sensor unit 200 divides the transparent panel into pixels and sets the coordinate values on the X-axis and the Y-axis of the transparent panel in the look-up table in advance, and when the electronic pen 100 approaches, The coordinate value is recognized and transmitted to the controller 300.

If the electronic pen 100 does not read the operation pattern even when the camera sensor 200 recognizes the coordinate value of the electronic pen 100, the flat panel display device 400 prevents the shape from being externally displayed.

As shown in FIG. 2, at least one camera sensor unit 200 is installed on the front upper end of the transparent panel 500, and continuously transmits an infrared signal to a reflective plate installed at the outermost part of the transparent panel 500. When the electronic pen 100 approaches, the electronic pen 100 is detected by using an infrared signal and the coordinate value of the electronic pen 100 is recognized.

The camera sensor unit 200 detects the approach state of the electronic pen 100 in real time by using the electronic pen detection range preset by the controller 300. That is, the electronic pen detection range may be set to 15 mm or less from the bottom surface of the transparent panel 500.

If the electronic pen 100 is out of the 15 mm height, the camera sensor 200 resets the coordinates of the electronic pen 100, and when the electronic pen 100 enters within 15 mm of the electronic pen 100, Recognize the coordinates.

As shown in FIG. 3, the camera sensor unit 200 scans an infrared signal in an electronic pen detection range having a minimum of 5 mm to a maximum of 15 mm from the bottom surface of the transparent panel 500 to approach the electronic pen 100. However, the infrared signal is scanned at an appropriate height of about 10 mm will be referred to as the electronic pen detection height that is most suitable for detecting the electronic pen 100.

The reason why the electronic pen detection range having a minimum of 5 mm to a maximum of 15 mm from the bottom of the transparent panel 500 is suitable for detecting the electronic pen 100 is that the user can make a shape desired by the transparent panel 500. In the case of a letter, it is necessary to use spaces or separate consonants or vowels for letters, and if there is a symbol, picture or figure, there is a need for a space between them.

At this time, when the camera sensor unit 200 detects the electronic pen 100 with an infrared signal scanned in the electronic pen detection range set to 5 mm or less from the bottom of the transparent panel 500, the electronic pen 100 As the entry, exit, re-entry, re-entry occurs too frequently spacing of the spacing, paste pasting, there is a fear that a shape that does not match the user's intention is shown on the transparent panel 500.

On the contrary, when the camera sensor unit 200 detects the electronic pen 100 by an infrared signal scanned in the electronic pen detection range set to 15 mm or more, the camera sensor unit 200 may enter, exit, re-enter or re-enter the electronic pen 100. Reacting too insensitively, the pen, paste, reentry, and reentrant of the electronic pen 100 can be spaced and pasted only by deliberately shifting up to 15 mm in height to show a shape suitable for one's intention. It may give inconvenience to the user who wishes to use.

Subsequently, when the camera sensor unit 200 probes the electronic pen 100 approaching within an optimal height of 10 mm, the camera sensor unit 200 detects the position of the probed electronic pen 100 and then probes the electronic The position of the pen 100 is applied to a preset lookup table, and the X-axis and Y-axis coordinate values of the probe electronic pen 100 are extracted from the look-up table.

In addition, when the electronic pen 100 is intended to show a shape desired by the user without departing from the optimum height of 10 mm, the control unit 300 continues to form the shape engraved on the transparent panel 500 without interruption. It judges that it exits and generates a display signal corresponding thereto.

However, when the electronic pen 100 reenters after leaving the optimum height of 10 mm, the control unit 300 is completely different from the shape already engraved on the transparent panel 500, or It determines that it is shown in the figure and generates another display signal corresponding thereto.

Here, as the camera sensor unit 200 recognizes the coordinate values of the electronic pen 100, the electronic pen 100 newly reads the operation pattern to generate another display signal.

The controller 300 recognizes that the coordinate value of the electronic pen 100 is recognized by the camera sensor unit 200, and receives a display signal transmitted from the electronic pen 100 through a local area network to which the flat panel display device is connected. 400).

The flat panel display 400 scans a display signal and drives the display signal to be externally displayed through the transparent panel 500.

The type of flat panel display 400 includes an organic light emitting diode (OLED), a plasma display panel (PDP), a liquid crystal display (LCD), and a vacuum fluorescent display (VFD), and the flat panel display 400 is one of them. By selectively selecting and inserting the screen touch function inside and installed in contact with the lower surface of the transparent panel 500 on the upper screen, the shape that is counted according to the touch of the electronic pen 100, the transparent panel 500 To be displayed.

The reflective plate 600 is installed at the outermost side of the transparent panel 500, and the infrared signal is continuously transmitted to the reflective plate 600 containing a plurality of glass particles, and then the electronic pen 100 is approached when the electronic pen 100 approaches. After the probe, the reflection plate 600 is reached by the diffuse reflection. Finally, the diffusely reflected infrared signal is input to the camera sensor unit 200.

Only so, the camera sensor unit 200 may detect the electronic pen 100 through the diffusely reflected infrared signal to recognize the coordinate value of the electronic pen 100.

Note that the reflective plate 600 contains a plurality of glass particles.

The reason for containing a plurality of glass particles in the reflecting plate 600 is that the infrared signal transmitted to the reflecting plate 600 through the camera sensor unit 200 does not probably disappear on the transparent panel 500 and finally the camera sensor unit By returning the reflection or diffuse reflection to the (200), when the electronic pen 100 is approaching to increase the probe rate of the electronic pen 100 to this will be to improve the performance of the entire system.

4 is a flowchart illustrating a method of driving an electronic blackboard system according to an embodiment of the present invention.

Referring to FIG. 4, a method of driving an electronic blackboard system reads an operation pattern according to a touch after recognizing coordinate values of an electronic pen when a user touches a shape desired by a user on a transparent panel with an electronic pen. The driving method generates a signal and scans a display signal so that the shape is externally displayed through a transparent panel.

First, the electronic pen attempts to approach a shape desired by the user on a transparent panel made of tempered glass or similar glass using a nib attached to a portion of the electronic pen (S10).

When the electronic pen approaches the transparent panel, the camera sensor recognizes the coordinate value of the electronic pen (S20).

As the camera sensor unit continuously transmits the infrared signal to the upper part of the transparent panel, the pen detects the electronic pen and recognizes the coordinate value of the electronic pen using the infrared signal when the electronic pen approaches.

In other words, the infrared signal continues to be transmitted to the reflector, and when the electronic pen approaches, the pen is probed and reached by the diffuse reflection. Finally, the diffusely reflected infrared signal is input to the camera sensor unit.

Note that the reflecting plate contains a large number of glass particles.

The controller determines that the coordinate value of the electronic pen is recognized by the camera sensor unit (S30).

When the pen tip of the electronic pen shows a shape that collectively refers to a letter, symbol, picture or figure by touching a part of the upper surface of the transparent panel (S40, S50), the electronic pen reads the operation pattern according to the touch. A display signal is generated (S60 and S70).

The controller receives the display signal transmitted from the electronic pen through the local area network and transfers the display signal to the connected flat display device (S80 and S90).

The flat panel display scans the display signal and drives the display signal to be externally displayed through the transparent panel (S100 and S110).

If the electronic pen does not read the operation pattern even when the camera sensor unit recognizes the coordinate value of the electronic pen, the flat panel display prevents the shape from being externally displayed.

Further operations of the electronic blackboard system driving method according to an embodiment of the present invention can be carried out as described below.

That is, the electronic pen detection range adjusted by the controller is set to 15 mm or less from the bottom of the transparent panel.

When the electronic pen leaves the electronic pen detection range, the camera sensor unit resets the coordinate value of the electronic pen. When the electronic pen enters the electronic pen detection range, the camera sensor unit recognizes the coordinate value of the electronic pen.

At this time, the electronic pen reads the operation pattern newly and generates another display signal.

The flat panel display drives external shapes through the transparent panel to display different letters, different symbols, different pictures, or different shapes collectively by scanning different display signals.

Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art will be able to variously modify and change the present invention without departing from the spirit and scope of the invention as set forth in the claims below. Will understand.
