DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0058] In the following description of embodiments, reference is made to the accompanying drawings which form a part hereof, and in which it is shown by way of illustration specific embodiments of the disclosure that can be practiced. It is to be understood that other embodiments can be used and structural changes can be made without departing from the scope of the disclosed embodiments.

First Embodiment

[0059] A touch blackboard is provided. As shown in FIG. 1. The touch blackboard includes a display unit 12, a middle unmovable blackboard 11, a touch film affixed on a back of a writing side of a glass blackboard, and two side splicable blackboards 13, 14. The splicable blackboards 13, 14 and the middle unmovable blackboard 11 are on a same plane. The touch film is affixed on a back of a writing side of the middle unmovable blackboard 11, and the display unit 12 is mounted on the back of the touch film. The display unit 12 has a less area than the middle unmovable blackboard 11, and is placed at a central position of the back of the middle unmovable blackboard 11. The touch film features the capability to achieve floating touch, or touch even through a nonmetallic object. The middle unmovable blackboard is made of a glass blackboard. The glass blackboard is an organic glass selected from a group of matte glass board, ultra clear glass board and nanometer glass. The glass blackboard is a glass material with a thickness that may be controlled within 5 mm-20 mm, and light transmittance larger than 80%. When the display unit 12 is turned on, a teacher can operate on the display unit with a finger or stylus through the middle unmovable blackboard 11. The glass blackboard may be a mimesis glass that when there is no touch-based input, the display may enter the hibernate mode, and the whole blackboard may look like a common glass blackboard; and when the display is required to be operated, it only needs a finger to touch the touch area lightly that the display restores to its displaying status. When the touch blackboard 12 is turned off, the teacher can write on the surface of the glass blackboard directly with a chalk or whiteboard marker. A lower part of the middle unmovable blackboard 11 is provided with various communication interfaces for communication connection with the display unit, including a network interface, USB interface and other common communication interfaces. The host of the display unit 12 is mounted with a wireless adapter, a wireless communication interface and a USB interface. The teacher can use a mobile device in his/her hand to transmit courseware to the display unit 12 via line or wireless way through these communication interfaces, for displaying. In this way, it facilitates realization of various communication connections, and usage of electronic documents and network resources.

Second Embodiment

[0060] As shown in FIG. 2, a touch blackboard includes a glass blackboard 21, a touch film affixed to the glass blackboard on a back of a writing side of the glass blackboard 21, and a display unit 22. In this embodiment, the glass blackboard adopts an integral structure to make the whole blackboard look one integrated mass, like a common glass blackboard, but it can realize functions of electronic whiteboard, multimedia playing, and interactive exhibition etc.

[0061] This touch blackboard not only has the function of the common blackboard, but also integrates the function of multimedia teaching, so it can completely replace the multimedia teaching mode made up of a projection system, and it is easier to operate and achieve interactive exhibition with students. In addition, this touch blackboard saves resources and reduces maintenance costs.

The blackboard frame 32 is rectangular, and two metal plate racks 33 are arranged on left and right sides inside the blackboard frame 32 respectively. The intelligent display device 31 is fastened to an upper beam and a lower beam of the blackboard frame 32 through the left and right metal plate racks 33, and the metal plate rack is provided with threaded holes for securing.

[0064] FIGS. 5 and 6 are space diagram and cross-section diagram illustrating a part of the blackboard frame according to this embodiment respectively. As shown, the frame member is a concave shape alloy material, and a raised retaining strip 322 is arranged at bottom of the concave shape alloy frame for placing and retaining the glass blackboard. The raised retaining strip 322 and the glass blackboard are on a same plane. The blackboard frame may be made of an aluminum alloy material with a stable structure and low cost. Alternatively, the blackboard frame may be made of stainless steel or other alloy materials.

[0065] FIGS. 7 and 8 are front view and left view illustrating a metal plate rack according to this embodiment respectively. A bent corner is arranged on either side of the metal plate rack 33, and the corner is provided with at least one threaded hole for securing the intelligent display device.

[0066] FIG. 9 is a front view illustrating a hook for securing the blackboard. The hook 38 is L shaped, provided with a threaded hole in its long side, and a raised part on its short side. The threaded hole is used to fasten the hook to the wall. The raised part matches the groove 321 of the concave shape alloy frame. In this way, the hook is easy to install, and can be fixed on the wall firmly and securely, by means of the structure of the concave shape alloy frame. Such hook is simple in structure and convenient in installation and maintenance.

[0067] The intelligence blackboard for classroom or large meeting room is preferably made up of three blackboards. One intelligence blackboard at middle has a larger area, and the intelligent display device is arranged on the back of the middle blackboard. Two smaller blackboards are arranged on two sides. This composite structure facilitates installation, transportation and flexibility of configuration.

Fourth Embodiment
