Description
Technical field
This utility model relates to a kind of electric ink plate display screen.
Background technology
In Ge great universities and colleges, middle and primary schools, blackboard is the most one of part and parcel in classroom, teaches a medium of knowledge as teacher.But the dust pollution of blackboard is also the biggest to the injury of student and teacher.Respiratory tract disease can be caused for a long time in the environment of dust is intensive.Many teachers are because winter occurs the phenomenon that hands is dry and cracked in long-time use chalk.If the LED screen power consumption using popular is the biggest, it is not suitable as the succedaneum of blackboard.
Summary of the invention
In order to solve, the pollution of present blackboard dust is big and inconvenient problem with use, the purpose of this utility model there are provided a kind of electric ink blackboard display screen, use electric ink panel type display to greatly reduce the impact on people of the blackboard dust, improve the service efficiency of blackboard.
In order to achieve the above object, the technical solution of the utility model is:
A kind of electric ink blackboard display screen, engages the engineering plastics cabinet back cover installed including engineering plastics cabinet fore shell with engineering plastics cabinet fore shell；On wherein said engineering plastics cabinet fore shell, backlight is installed, described backlight is provided with electric ink display screen；On described engineering plastics cabinet fore shell, CPU, mainboard, USB interface, key control panel, hard disk, power device, the first LED display and the second LED display are installed.
On described engineering plastics cabinet back cover, alloy suspension holdfast is installed.
During use, turn on the power key, only need as using blackboard, and the size of notes can be regulated, allow the classmate of heel row also can see notes clearly.Can preserve the writing on the blackboard write on blackboard in time, classmate can copy back with the notes that teacher is attended class by USB after class simultaneously, convenient review.
The beneficial effects of the utility model are: a kind of electric ink blackboard display screen of the present utility model can facilitate teacher to write writing on the blackboard on blackboard, facilitates student to record and copies writing on the blackboard, improves the efficiency that blackboard of attending class uses.Reduce the harm that Faculty and Students' respiratory tract is caused by blackboard dust, and use electronic ink screen, energy consumption can be greatly reduced.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the partial enlarged drawing of engineering plastics cabinet fore shell in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described further.
As shown in Figure 1, 2, a kind of electric ink blackboard display screen of the present embodiment, engage the engineering plastics cabinet back cover 4 installed with engineering plastics cabinet fore shell 3 including engineering plastics cabinet fore shell 3；Backlight 2 is installed on wherein said engineering plastics cabinet fore shell 3, described backlight 2 is provided with electric ink display screen 1；CPU9, mainboard 13, USB interface 6, key control panel 11, hard disk 10, power device the 12, first LED display 7 and the second LED display 8 are installed on described engineering plastics cabinet fore shell 3.On described engineering plastics cabinet back cover 4, alloy suspension holdfast 5 is installed.Alloy suspension holdfast 5 is for being fixed on classroom wall by electric ink blackboard.
During use, open the power key on key control panel 11, only need as using blackboard, and conventional pen can be utilized to alter on the first LED display 7 and the second LED display 8, write, all can show on electric ink display screen 1；And key control panel 11 regulates the size of notes, allow the classmate of heel row also can see notes clearly.Can preserve the writing on the blackboard write on blackboard in time, classmate can copy back with the notes that teacher is attended class by USB interface 6 after class simultaneously, convenient review.
