True Interactivity Bringing People Together
Up to 20 multitouch points can be used at once with the TR3DJ series. With this feature, you will experience a lifelike board touch experience that makes collaboration much easier.
Because the TR3DJ series has a 1mm gap between the screen and tempered glass, which allows for low parallax, the TR3DJ series offers precise touch and an improved writing experience.
With two different tip sizes of 3mm and 8mm, the stylus pen is available in two colors. Both pens can be used simultaneously for writing or drawing.
With the LG Interactive Display 75TR3DJ series, you can write and annotate on sources, making the writing process easy and enjoyable.
Up to 30 students can connect using Air Class, with interactive meetings for mobile devices over the same network, where they can vote, answer, and share project texts. TR3DJ's main toolbar easily displays the Air Class section.
TR3DJ series boards include OPS* slots so you can connect an OPS device without using an external desktop, providing you with more functions and convenience.
* OPS : Open Pluggable Specification
ScreenShare Pro allows you to share up to six screens or a file in real-time on a single screen, and it allows you to share Chromecast and Apple device mirroring on the same network without requiring any additional software.
A variety of Bluetooth wireless devices, such as speakers, mice, keyboards, etc., can be used with TR3DJ. This approach is ideal for building a hybrid environment that makes it easy to conduct online and offline meetings.
You can use the TR3DJ series to search the web without having to connect to an external tablet or computer thanks to an embedded Android web browser.
Access the tool you need with ease thanks to the Toolbar. Annotations work on nearly all file types, and the Spotlight function allows you to highlight the section you want to emphasize. You can manage class time more effectively with the countdown and stopwatch features.
Speakers are integrated into both sides of the bezel of the TR3DJ series, providing a clear audio experience.
With USB Block Mode, you can prevent unauthorized devices from accessing your data. This is essential when used in sensitive environments.
