The purpose of the utility model is to provide a dual-screen touch interactive electronic blackboard, which can effectively increase the capacity of displayed information, and the shape of the electronic blackboard is close to that of a common blackboard.

For achieving the above object, the technical solution of the present utility model is as follows:

A dual-screen touch interactive electronic blackboard includes an electronic writing screen and an electronic display screen; the electronic writing screen is a combination of a touch display device and a computer with a dual-screen display card; The display interface of the computer of the card is connected with the signal input interface of the electronic display screen by the display data signal line; the electronic writing screen controls the display of the electronic display screen.

The electronic writing screen is an LCD touch all-in-one computer with a dual-screen display card, or a liquid crystal touch display externally connected to a computer with a dual-screen display card, or a projection of an external computer with a dual-screen display card. Touch the display device.

The electronic display screen is an electronic flat display device with HDMI and VGA display signal input, which can be a TV set, a liquid crystal touch display, or a combination of a projection screen and a projector.

In order to make the appearance and shape of the dual-screen touch interactive electronic blackboard closer to the ordinary blackboard, and also for aesthetics, a frame can be set around the electronic blackboard, and the frame is the corner line of various materials with decorative effect or the frame frame of the mirror.

In addition, in order to solve the problem of subsequent expansion of the display information capacity of the electronic blackboard, based on the above design, an image splicing processor can be fixed on the back of the electronic writing screen, and the electronic writing screen can pass the dual-screen display card of the computer on it. The display interface is connected with the signal input port of the image splicing processor by a display data signal line, and a signal output port of the image splicing processor is connected with the signal input interface of the electronic display screen through the 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 present utility model:

The dual-screen touch interactive electronic blackboard of the utility model is composed of an electronic writing screen and an electronic display screen. The design effectively increases the capacity of the electronic blackboard to display information. The outer periphery of the electronic blackboard is more beautiful and elegant, and its appearance is closer to ordinary blackboard. If the electronic display screen is replaced by a combination of a projector and a white matt board that can be used as a screen, this design can also use the white matt board as a common writing board.
