The two touch screens respectively collect the content written on the two blackboards; the blackboard 100 and the second blackboard 500 are respectively disposed at both sides of the display screen 300, in this embodiment, the display screen 300 is installed at the center on the front wall of the classroom, the blackboard 100 and the second blackboard 500 are installed at both sides, and the touch screen 200 and the second touch screen 600 are respectively stacked on the blackboard 100 and the second blackboard 500.
In this embodiment, there are also a display screen 300 and a display control host 400; the display screen 300 is disposed between the blackboard 100 and the second blackboard 500; in practice, if the host of the display screen 300 has a relatively high processing capability, the display control host 400 and the host of the display screen 300 may be integrated into one. In this embodiment, the display screen 300 is a display screen having a wide display area, such as a display screen half the width of the front wall of a classroom. The sum of the areas of the two blackboards in the whole display area is in a relatively standard configuration, and certainly, more display screens can be used, for example, the width of each display screen is 2 times that of the corresponding blackboard, and the height of each display screen is consistent with that of the corresponding blackboard or is twice that of the corresponding blackboard.
In this embodiment, the display control host 400 is connected to the touch screen 200, the touch screen 200 and the second touch screen 600, respectively, and displays the contents acquired by the two touch screens on the display screen 300. During display, the display area can be divided into two parts, and the contents collected by the two touch screens are respectively displayed, that is, the contents written, drawn and scratched by a teacher on the two blackboards.

In fact, the shortcut function area 110 can be set with different numbers as required, the functions of the shortcut keys are flexible and customizable, and some functions commonly used at present include preview, screen clearing, new page creation, page turning up and down, pen color adjustment (red, yellow and white), voting, code scanning and sharing, and the like. The position of the shortcut key is flexible, and the shortcut key can be close to the middle host, the left side and the right side, and the lower side.
The blackboard 100 and the second blackboard 500 can be common planar blackboards, such as blackboards with a friction-increasing layer of paint on a acryl board to facilitate chalk writing, or other blackboards, or anti-glare black perspective glass with a surface roughness of 0.3-0.4 μm or other specifications. At present, such an anti-glare black glass is widely used for manufacturing blackboards. The production method of the anti-dazzle black perspective glass is high-temperature spraying or chemical dissolution, wherein: the high-temperature spraying comprises the following steps: spraying glass powder with the particle size of 0.3-0.9 mu m on the surface of the anti-dazzle black perspective glass at the temperature of 300-350 ℃ to change the flatness of the surface of the anti-dazzle black perspective glass; chemical dissolution: the method comprises the steps of preparing an acid solution by using concentrated acid with the purity of 65-85% and water according to the proportion of 1: 1-1: 2, and uniformly spraying the acid solution on the surface of the anti-glare black perspective glass to destroy the flatness of the surface of the anti-glare black perspective glass. In fact, under the condition that the interconnection boards on the two sides are infrared touch, the panel can be made of a blackboard, a green board or a white board; if the touch is capacitive, the panel can only be toughened glass; if the infrared touch frame is selected, the blackboard can be matched with a liquid crystal handwriting board.
In this embodiment, the blackboard 100 may also be a light energy liquid crystal blackboard, and an infrared touch screen is used around the light energy liquid crystal blackboard, at present, the light energy liquid crystal blackboard is often used as a writing pad, and the light energy liquid crystal blackboard can be directly written on the writing pad by using fingers or a hard pen without using chalk, and the infrared touch screen is arranged around the blackboard 100, so that the content written on the blackboard by a teacher can be used on the middle display screen. Compared with the common blackboard, the blackboard has higher price, but can display and reduce the pollution of chalk dust because the blackboard can be directly written by hard objects without chalk.
In this embodiment, the display screen 300 has a wide selectable range, and may use a common display screen or a special display screen, in this embodiment, a large-screen touch display all-in-one machine is used, and sometimes, projection may be selected according to the amount of budget, at this time, a projection area is reserved in the middle of two blackboards, of course, two or more blackboards with touch screens may be combined together, the projection area is on the blackboards, which are all set as required, and the display control host 400 may also be combined with the host of the projector as required. With the development of electronic technology, the price of the current LED display screen is also decreasing, and in this embodiment, the cost of the large-screen LED display screen is also decreasing to a reasonable range.
In this embodiment, the display control host 400 is composed of software and hardware, and displays the content collected by the touch screen 300 on the display screen by using the existing technology in the field, and an appropriate display method can be selected from the existing display methods according to the need. In this embodiment, the content, such as a teacher writing and drawing on a blackboard, is directly displayed on the display screen 300, and as with a photo, the picture can be saved even by the time without processing. Of course, in other embodiments, some chinese character systems or other pattern recognition systems may be used to recognize the contents of the strokes written by the teacher to form a text, and the text is displayed on the display screen, and of course, some patterns may be inserted into the text. In a word, the display control method is many at present, and the teaching requirement is completely met. In addition, in this embodiment, when it is found that a chinese character or a digital character is written on the blackboard during debugging, and when it is found that an image of these chinese characters or digital characters is displayed on the display screen, the reduction-weight is compared, and therefore, the image is compressed a little in the height direction, and in this embodiment, the compression ratio is 1: 90-98%, and the compression module is set by the skilled person according to the needs, and the human can adjust the compression ratio in the background.
The touch screen is a medium corresponding to the blackboard and the display screen in the embodiment, and maps the track of a teacher holding chalk during demonstration on the blackboard to the display screen in real time. In this embodiment, different touch screens may be adopted according to the budget, for example, in this embodiment, an infrared touch screen is adopted, and the transmitting and receiving modules of the infrared touch screen are disposed around the blackboard 100, and at this time, there is no requirement for chalk, because the touch area is determined by blocking the infrared ray. With the development of electronic technology, the cost of the capacitive touch screen is greatly reduced, and compared with an infrared touch screen, the price advantage of the infrared touch screen is smaller and smaller, so that in other embodiments, the capacitive touch screen can also be adopted, and the total investment is increased by less than 10%. Because the capacitive touch screen needs to be scratched by a finger and other conductors in a touch area, and the finger cannot scratch the blackboard, a special chalk needs to be used, and a conductive chalk is adopted, wherein the conductive chalk is prepared by adding conductive powder into a chalk raw material.
