BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a display system, and more particularly an interactive display system.

2. Description of the Related Art

A conventional display device is used for displaying a video signal processed by a main controller of the display device. Namely, the conventional display device is just a display interface that cannot directly interact with a user. There is already a display device having a camera that cooperates with sensors to capture actions of the viewer. When the main controller of the display device receives signals from the camera and the sensors, the main controller converts the signals into an image corresponding to the user, and displays the image on a screen of the display device.

However, the display device having the camera can only display the image corresponding to the user, but the user still cannot interact with content displayed on the screen of the display device. Therefore, the conventional display device needs to be improved.

SUMMARY OF THE INVENTION

To overcome the aforementioned drawback, an interactive display system of the present invention can provide interactions between a user and a display device.

The interactive display system includes a display device and a user device.

The display device includes a memory unit, a controlling unit, and a plurality of lighting units. The memory unit stores a color signal. The controlling unit is electrically connected to the memory unit. The lighting units are electrically connected to the controlling unit, and the controlling unit transmits the color signal to the lighting units.

The user device includes an emitting unit. The emitting unit emits an active light signal. When the emitting unit emits the active light signal to at least one of the lighting units, the at least one of the lighting units that receives the active light signal lights up according to the color signal.

Since the lighting units an react with the active light signal, the user can use the user device with the emitting unit to interact with the display device. For example, when the user uses the emitting unit to emit the active light signal to the lighting units of the display device, the lighting units illuminated by the active light signal can light up. Namely, the user can use the display device as a canvas, and the user can draw a picture or write a memo on the display device. Therefore, the user can interact with the display device of the interactive display system of the present invention.
