This has brought about a macroscopic problem that the touch interactive electronic blackboard is low in use rate. Therefore, the problem of small information display capacity of the touch interactive electronic blackboard is urgently solved at present.
The utility model has the following contents:
an object of the utility model is to provide a double screen touch interactive blackboard, this blackboard can effectively improve the capacity of display information, and blackboard's shape is close the shape of ordinary blackboard.
In order to achieve the above object, the technical solution of the present invention is as follows:
a double-screen touch interactive electronic blackboard comprises an electronic book writing screen and an electronic display screen; the electronic writing screen is a combination of a touch display device and a computer with a double-screen display card; the electronic book writing screen is connected with a signal input interface of the electronic display screen by a display data signal line through a display interface of a computer with a double-screen display card; the electronic writing screen controls the display of the electronic display screen.
The electronic book writing screen is a liquid crystal touch all-in-one machine of a computer with a double-screen display card, or a liquid crystal touch display of the computer externally connected with the double-screen display card, or a projection touch display device of the computer externally connected with the double-screen display card.
The electronic display screen is an electronic flat display device with HDMI and VGA display signal input, and can be a television, a liquid crystal touch display, or a combination of a projection screen and a projector.
In order to enable the appearance shape of the double-screen touch interactive electronic blackboard to be closer to that of a common blackboard and to be attractive, frames can be arranged around the electronic blackboard, and the frames are corner lines or frame frames and the like made of various materials with decorative effects.
In addition, in order to solve the problem of subsequent expansion of the display information capacity of the electronic blackboard, an image splicing processor can be fixed on the back of the electronic book writing screen on the basis of the design, the electronic book writing screen is connected with a signal input port of the image splicing processor through a display data signal line through a display interface of a double-screen display card of a computer on the electronic book writing screen, and a signal output port of the image splicing processor is connected with a signal input interface of the electronic display screen through a display data signal line.
The image stitching processor is a 2 × 2 image stitching processor with one input and four outputs.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses an interactive blackboard of double screen touch comprises electronic writing screen and electronic display screen, and this design has effectively improved the capacity that electronic blackboard shows information, and this electronic blackboard periphery is more elegant appearance behind the frame in addition, and the outward appearance shape is more close ordinary blackboard. If the electronic display screen is replaced by a projector and a white matte board combination which can be used as a curtain, the design can also use the white matte board as a common writing board.
