2. Description of the Prior Art

The current electronic whiteboards are widely used for demonstration instead of the conventional whiteboards. The market occupation rate of the electronic whiteboards is greatly increased. However, the display panel of such electronic whiteboard is quite heavy. Therefore, structurally, it is necessary to frame the display panel with a rigid frame or fix the display panel on a wall. In general, the weight of the display panel of the conventional electronic whiteboard is about 3050 kilograms. Therefore, it is quite inconvenient to install the electronic whiteboard. Moreover, in case the electronic whiteboard is not firmly mounted or after a long period of use, the electronic whiteboard tends to loosen and fall off from the wall to hurt a user or other people.

In addition, it is impossible for a user to carry the heavy electronic whiteboard with him/her. Therefore, each application site necessitates a set of electronic whiteboard which is fixedly mounted. Consequently, the cost for the equipment and installation is very high so that the electronic whiteboards still cannot be popularly used.
