Multi Touch & Writing

The TR3BF Series can simultaneously use up to 20 points of multitouch and 10 points of writing, as well as 2 types of stylus pens. This function offers a lifelike board writing experience and makes collaboration much easier.


Palm erasing

The TR3BF Series allows you to easily erase texts, pictures, etc, written on the screen by using your own hands. This is not only easier than erasing with the stylus, but also makes you feel more natural, like you’re erasing a real whiteboard.


Air Class

Air Class supports connecting up to 30 students and offers interactive meetings for all mobile devices on the same network, providing a variety of tools such as voting, answering, and sharing project texts.


Screen Sharing

The TR3BF Series allows you to share screens and content with laptops and other mobile devices. This makes meetings and classes as efficient and immersive as possible.


Built-in OPS kit

The TR3BF Series supports OPS slots, allowing you to easily and conveniently mount OPS desktop at the back of the digital board without the hassle of connecting to an external desktop, offering you more expanded functions.


Web browser

The TR3BF Series can use the Chrome web browser which is built into the Android OS, so you can search the web easily and quickly, without the need to connect to an external desktop.


All-in one

The TR3BF Series integrates both Android and Note Apps into a high performance SoC, without a PC.


Various size with Ultra HD

Using UHD resolution will allow you to view details at a resolution that is four times higher than FHD, even while zoomed in. Various content such as documents, images, and videos are displayed without any distortion of image quality, which is especially important in an educational and collaborating environment.


True Color, Immersive View

The TR3BF Series shows multimedia content for the attendees more vividly. The IPS panel clearly displays content at various angles, regardless of where attendees are sitting. Each pixel of the IPS panel reproduces the actual image’s color without any distortion.
