Core Product Features

1. Intelligent System Core

(1) Android 11.0 Professional Education System

Equipped with native Android 11.0 intelligent system, customized 4K ultra-high-definition UI interface - from the main menu to the application icon, it uses 3840×2160 resolution rendering to present a delicate visual experience like real blackboard writing, adapting to the high-precision display requirements of educational scenarios.

(2) Powerful 64-bit processor architecture

Adopting a quad-core ARM Cortex-A55 high-performance chip, the main frequency has a dynamic adjustment range of 1.5GHz-1.92GHz, and supports multi-task parallel processing: when running courseware demonstrations, video playback and multi-person touch annotations at the same time, it still maintains smooth response to meet the high-density interaction needs of the classroom.

2. Industrial design and touch interaction

[Minimalist aesthetics × precision craftsmanship]

14mm ultra-narrow optical frame: Made of black matte metal, the screen-to-body ratio is increased to 92%, suitable for multiple classroom installation scenarios, visually weakening the presence of the device and focusing on the teaching content itself.

Front detachable infrared touch frame: Touch accuracy reaches ±1mm, sensing height ≤1mm, supports 20 points of simultaneous touch - teachers and students can write, drag, zoom and other operations simultaneously, and with the low-friction glass panel, a smooth writing experience like paper and pen is achieved.

[Extended functions and security design]

(1) Dual system expansion interface: Built-in standard OPS interface, supports seamless access to Windows system modules, builds an Android + Windows dual system collaborative environment, and is compatible with different educational software ecosystems.

(2) Cross-system USB sharing: The front USB interface supports two-way data communication between computers and Android systems. Peripherals such as USB flash drives and styluses can be shared without switching devices, improving classroom operation efficiency.

(3) Network cable aggregation (optional): A single network cable is used to achieve synchronous networking of the Android system and the OPS host, simplifying classroom wiring and adapting to the network requirements of multimedia teaching environments.

(4) Multi-theme interface switching: Supports scenario-based theme switching such as teaching mode and conference mode, and the interface layout is intelligently adjusted according to the usage scenario; when an external USB device is connected, permission authentication is automatically triggered, and access is required with a password unlock to ensure the security of teaching files.

Jiangsu Qilong Electronic Technology Co.,LTD.is a factory located in China. Specialized in producing Education Interactive Board, such as Interactive conference board, Memory blackboard, Smart blackboard,Training Interactive Board，etc.
