When school procurement teams and enterprise buyers compare different interactive smart board brands, many only focus on price and screen size. However, ignoring core functions will lead to poor user experience after purchase. ELON lists five essential features you should check before ordering interactive flat panels. First: Multi-point infrared touch performance. Confirm whether the panel supports at least 20-point simultaneous touch. High-quality ELON smart boards support multiple users writing together. Avoid low-cost products that only support 2 or 4 touch points, which will restrict interactive teaching and group discussion. Second: Anti-glare tempered glass. Rooms with windows usually have strong natural light. If the screen does not have anti-glare treatment, reflection will make content hard to watch. All ELON interactive boards adopt anti-glare, anti-scratch tempered glass to adapt to bright classroom and office environments. Third: Built-in complete whiteboard & casting software. Many cheap panels only provide basic hardware without mature supporting software. ELON pre-installs original whiteboard software, wireless screen share, split screen function. Users do not need to buy extra paid software for daily teaching and meetings. Fourth: Dual system switching (Android + Windows OPS). Flexible dual system is very practical. Teachers can use the built-in Android system for quick classes; plug in OPS computer to switch Windows for complex software, courseware and offline files. ELON supports customizable OPS modules for all panel sizes. Fifth: Stable after-sales and firmware update service. Interactive boards are long-term equipment that works for 5–8 years. Regular firmware updates fix compatibility bugs. ELON offers continuous software updates and global technical support for all our partners and project clients.
