Function and use: the value extension of lcd advertising machine display screen of nano blackboard teaching integrated machine from basic display to deep interaction.
Lcd advertising machine display screen, a nano-blackboard teaching integrated machine, is not limited to "replacing the blackboard", but realizes the value upgrade from basic information display to deep interaction and cooperation through functional integration.
In terms of teaching purposes, the core value of the lcd advertising machine display screen of the nano blackboard teaching integrated machine is reflected in three aspects:

One is "efficient lesson preparation and demonstration". Teachers can quickly import courseware through the U-disk, the lcd advertising machine display screen of the nano-blackboard teaching integrated machine, or the wireless projection screen.
With the help of the touch function, they can mark the key points and support one-click saving of the blackboard contents (generating pictures or PDF) for easy sharing with students after class.
The second is "classroom interaction upgrade". Through the built-in answering software and voting function on the lcd advertising machine display screen of the nano blackboard teaching machine, real-time classroom detection can be realized. Students can participate in the interaction by scanning the code on their mobile phones, and teachers can check the answer results immediately and adjust the teaching rhythm.
Third, "interdisciplinary adaptation", such as drawing dynamic geometric figures in mathematics teaching, playing experimental videos in physics teaching, showing texts with pictures in Chinese teaching, and lcd advertising machine display screen of nano-blackboard teaching machine meeting the teaching needs of different disciplines.

In business use, the value of lcd advertising machine display screen of nano-blackboard teaching integrated machine focuses on "improving meeting efficiency" and "optimizing collaborative experience";
On the one hand, the lcd advertising machine display screen of the nano-blackboard teaching integrated machine supports simultaneous screen projection of multiple devices (such as computers, mobile phones and tablets), which can quickly switch the presentation content and avoid the tedious operation of "plugging and unplugging U-disks" in traditional meetings.
On the other hand, participants can directly annotate and modify the scheme on the lcd advertising machine display screen of the nano-blackboard teaching integrated machine, and the modified content can be saved in real time, and can be sent to participants by scanning code or email after the meeting, thus reducing the information transmission error.
In addition, some models support teleconferencing software (such as Tencent Conference and Zoom), and the lcd advertising machine display screen of nano-blackboard teaching integrated machine can realize real-time collaboration among teams in different places and improve the efficiency of cross-regional communication.
For daily management purposes, the lcd advertising machine display screen of the nano-blackboard teaching integrated machine can also be used as an "information release terminal": in areas such as school corridors and enterprise halls, notices, activity announcements, safety tips, etc. can be played circularly.

On holidays or special nodes, the lcd advertising machine display screen of nano-blackboard teaching integrated machine can display blessing pictures or theme propaganda content, which is both practical and atmospheric.
To sum up, the lcd advertising machine display screen of nano-blackboard teaching integrated machine not only solves the pain points in traditional teaching and office, but also reconstructs the mode of information interaction through its safety and durability in appearance, high-definition and stability in performance, wide adaptation in scenes and diversified extension in use, and becomes an important tool to promote educational intelligence and office digitalization.
With the continuous upgrading of technology, the potential of lcd advertising machine display screen, a nano-blackboard teaching machine, in terms of functional integration and AI interaction will be further released, creating value for more scenes.
