Nano Smart Blackboard

The fusion and innovation of traditional teaching and nanotechnology, reconstructing efficient interactive classroom

Core technical advantages

1. Nano touch interactive experience

Precise multi-touch: Using nano-level sensing technology, supporting 10-point synchronous touch, one or both hands can smoothly write, erase, and zoom the blackboard content, and the operation response speed is <5ms

Natural writing experience: imitating the damping design of chalk writing, the thickness of the handwriting changes intelligently with the pressure, supporting gesture erasure (palm wiping) and area zooming, restoring the traditional blackboard usage habits

2. Immersive high-definition display

4K ultra-high-definition large screen: resolution of 3840×2160, 99% sRGB wide color gamut restores true colors, anti-glare tempered glass panel reduces ambient light interference, and students in the back row can be clearly seen

Multimedia seamless display: support 4K video, 3D Courseware and dynamic charts are played in real time, images are scaled without distortion, and the derivation process of complex formulas is presented delicately.

3. Intelligent interactive teaching system

Quick gesture control: two-finger sliding to turn pages, three-finger to call up calculator/timer, long press the screen to quickly search for teaching resources, and classroom operation efficiency is improved by 40%

Software deep adaptation: built-in Android 11 system, compatible with mainstream teaching platforms such as DingTalk Classroom/Tencent Conference, support PPT/Excel/PDF to open annotations directly, and courseware does not need to be converted twice

Environmentally friendly and durable design

1. New paradigm of green teaching

Zero dust pollution: electronic blackboard replaces traditional chalk, eliminates the harm of dust to the respiratory tract of teachers and students, and cooperates with intelligent sleep mode, with an average daily energy consumption of <3 degrees, saving 60% of electricity compared with traditional equipment

Full life cycle environmental protection: no paper consumption, nano-coated panels are recyclable, comply with RoHS environmental certification, and help campus carbon neutrality construction

2. Industrial-grade durable quality

Six-proof surface treatment: dustproof, waterproof (IP5X level), wear-resistant (7H Hardness), anti-glare, anti-fingerprint, anti-impact, daily cleaning with a damp cloth, 5 years of use without scratches

Modular structure: core components support quick replacement, maintenance costs reduced by 50%, adapt to high-frequency teaching scenarios for long-term use

Full-scenario adaptability

1. Flexible deployment plan

Mobile design: optional universal wheel bracket, 3 minutes to complete the classroom movement, adapt to multiple classes shared use or temporary training scenarios

Wall-mounted installation: ultra-thin body (thickness <5cm) fits the wall, saves classroom space, compatible with standard VESA bracket for quick installation

2. Cross-platform seamless connection

Full device compatibility: supports HDMI/Type-C/USB3.0 interface, mobile phone/tablet/computer wireless screen projection (Miracast/AirPlay), reverse control of external device interface

Multi-system adaptation: compatible with Windows/macOS/Linux/Android, seamlessly connected to the existing campus IT Equipment, protect initial investment

Core value: With nano touch technology as the core, create an intelligent teaching terminal with "writing as natural as a blackboard, display as clear as a large screen, and interaction as convenient as a tablet", helping schools to achieve comprehensive upgrades in environmentally friendly classrooms, efficient classrooms, and interactive classrooms.
