Introduction to Smart Interactive Flat Panel Products

Integrated design reconstructs efficient interactive experience

I. Immersive display system

(I) 4K ultra-high-definition picture quality

Equipped with a 4K resolution display (3840×2160), it adopts a zero-degree bonding process to integrate a high color gamut panel (1.07 billion color display), and the color reproduction reaches 99% sRGB. Whether it is courseware presentation, video playback or whiteboard writing, the picture details are clear and transparent. The front anti-glare coating effectively reduces ambient light interference and supports normal use in direct sunlight, meeting the needs of multi-light source scenes such as classrooms and conference rooms.

(II) Convenient interface configuration

The front dual USB 3.0 interface supports plug-and-play and is compatible with peripherals such as USB flash drives, digital tablets, and cameras. With the intelligent switching technology, the device type can be identified without manual settings, greatly improving the efficiency of device connection. The HDMI interface supports 4K 60Hz ultra-high-definition input and output, and is compatible with mainstream computers, set-top boxes and other devices to achieve high-speed audio and video transmission.

II. Intelligent core and system architecture

(I) Flexible dual-system adaptation

Built-in Android 11.0 intelligent operating system, equipped with 4K UI interface and exclusive whiteboard software, supports native 4K resolution writing, and the handwriting edges are smooth and without jagged edges. Optional pluggable OPS PC module (needs to be purchased separately), supports Windows 10/11 system, and switches between Android/computer dual systems with one physical button to meet software compatibility requirements in different scenarios.

(II) Integrated core design

Adopting an integrated architecture of display, touch, and intelligent core, integrating a high-definition image processing engine and a dedicated display chip, optimizing video decoding and picture rendering efficiency, supporting simultaneous running of whiteboard writing, video conferencing, courseware presentations and other multi-tasks without lag, and increasing system response speed by 30%.

III. Precision touch interaction technology

(I) Anti-interference touch experience

Equipped with industrial-grade touch sensors, it supports 10-point synchronous touch. The touch algorithm has been optimized for 200+ scenes, with a writing delay of <8ms and strong handwriting tracking. Whether it is fast blackboard writing or fine drawing, it can be presented smoothly. The unique anti-light interference technology can filter more than 90% of the ambient light, and the touch positioning accuracy remains unchanged under direct sunlight, ensuring stable use in outdoor or bright classroom scenes.

(II) Full-channel annotation function

Supports real-time annotation in any signal channel (HDMI/USB/wireless projection). You can circle key points and add text descriptions with gestures or pen strokes without switching interfaces. The annotation content is automatically superimposed on the current screen, and supports one-click saving or sharing to the cloud, meeting the needs of instant classroom annotation and real-time recording of meetings.

IV. Intelligent and convenient function design

(I) Intelligent wake-up and energy saving

It has the function of intelligent wake-up of HDMI signal. When the external device input is detected in standby mode, the screen will be automatically lit. The response time is less than 5 seconds, avoiding the tedious operation of manual power on and off. It supports the "one-button breathing board" mode, which can quickly enter the low-power standby mode through the physical button, reducing energy consumption by 70%, while extending the service life of the screen, and the average daily power consumption is less than 2.5 degrees.

(II) Humanized operation experience

It adopts a double-button one-button power on and off design. Long press for 3 seconds to start the Android system and the optional PC module at the same time. The user-defined homepage is entered by default when the machine is turned on. It supports the channel memory function (such as the HDMI channel used last time, it will jump directly to the next time it is turned on). The channel name can be customized and edited to facilitate the distinction between different scene configurations such as "teaching mode" and "conference mode".

V. Summary of core advantages

Integrated integration: deep integration of display, touch, and intelligent system, no external host or converter is required, saving space and reducing failure points.

Cross-platform compatibility: Android system meets the needs of lightweight interaction, and the optional PC module supports professional software operation, which is suitable for all scenarios of education and conferences.

Ultimate durability: anti-light interference touch, low power design, channel memory function, taking into account both performance and equipment life, suitable for high-frequency use environments.

Applicable scenarios: smart classrooms in primary and secondary schools, medium-sized corporate conference rooms, and training centers, providing a full-process digital solution from content display to real-time interaction, helping to improve teaching efficiency and conference quality.
