The electronic teaching display screen with the projection curtain has the advantages of novel design, convenient compatible usage of a traditional projector, convenient usage, low cost, and convenient popularization and application.
Description
Technical field
The utility model relates to a kind of electronics teaching aid, specifically refers to a kind of electronic type teaching display screen that has projection screen.
Background technology
Along with the continuous development of electronic technology and deeply, traditional blackboard is projected instrument gradually and multimedia computer substitutes, though be enhanced in display effect, but, lack the on-the-spot hand-written deduction of teaching board, on teaching efficiency, can't substitute traditional blackboard fully.
By retrieval, Chinese patent application is number for 200820075663.X discloses the sub-display screen of a kind of teaching consuming energy, and its structure employing touch-screen designs, can directly write thereon, still, in teaching, in order to make the student can obtain better visual effect, its necessity needs large-sized touch-screen, yet, at electronic applications, large-sized touch-screen cost is very expensive, therefore, the electronic type of this quasi-tradition teaching display screen price height is difficult to apply.
For this reason the inventor in first to file a kind of electronic type teaching display screen (Chinese patent application number is: 201220550378.5) solved the problems referred to above preferably.But, in the application process of reality, but have following problem: there have been projector and projection screen in traditional middle and primary schools classroom, after electronic type teaching display screen has been installed, the teacher still wishes to keep traditional projector functions, and the space in middle and primary schools classroom is fixed, and this electronic type teaching display screen is installed, cause the projection screen of projector to be installed nowhere, cause projector normally to use.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming and defect that prior art exists, and a kind of reasonable in design is provided, and can allow the normal a kind of electronic type teaching display screen that has projection screen that uses of projector in existing middle and primary schools classroom.
For achieving the above object, the technical solution of the utility model is to include electronic type teaching display screen, and this electronic type teaching display screen includes following assembly:
Electronic display;
Arm processor, this arm processor is connected with USB control module and video driving module, and described electronic display is connected with video driving module,
The crystal oscillator module is connected on the ARM process chip, is used for providing clock signal;
USB interface is connected on the USB control module of arm processor, is used for connecting the USB peripheral hardware;
Be connected with the HDMI control module on the described arm processor, this HDMI control module is provided with the HDMI interface, and this HDMI interface is used for connecting panel computer;
Be connected with the SDRAM storer on the described arm processor, be used for the temporary and buffer memory of data;
Be connected with the FLASH storer on the described arm processor, the steering order that is used for arm processor stores;
The upper end of described electronic display is set with the projection screen reel, is provided with projection screen around volume in this projection screen reel, and the bottom of described projection screen fixedly installs the pasting board that is magnetic, and the bottom of described electronic display is provided with the ferromagnetic metal underframe.
Further arranging is that described ferromagnetic metal underframe is the stainless steel underframe.
The utility model has the advantages that: projection screen reel and projection screen are arranged to electronic display, when the needs projection, put down projection screen and can normally use projection, and when needing electronics to show, furled projection screen then, can normally use electronic display, it is flexible and convenient to use, especially is fit to tradition has been had the usefulness that projector and needs install the classroom repacking of electronic display additional.
In addition, the utility model is by being provided with the HDMI interface, just can carry out the transmission of Voice ﹠ Video data with very general panel computer (as IPAD series etc.) on the existing market by data conversion line, the teacher is when teaching, directly carry out hand-writtenly at IPAD, just hand-written process can be synchronized on the electronic display, therefore, the student can understand the hand-written deduction of teaching board intuitively, improves the quality of teaching.By the utility model, because hand-written process no longer on the electronic display, therefore need not the very high touch-screen of purchase cost, and can directly adopt LCD or LED display get final product, greatly reduced cost, help the impart knowledge to students popularization of display of electronic type.
Below in conjunction with specification drawings and specific embodiments the utility model is done further introduction.
