As these tasks become more complex and difficult, collaborative meetings have become a key to success for businesses. The Interactive Digital Board (IDB) has been developed as a means of maximizing the effectiveness of such meetings, aiming to reduce spending time and costs unnecessarily. The use of IDB will be extended beyond general business meeting rooms to various places such as fashion design offices, hospitals, military command centers, and architectural offices.

With the most advanced built-in touch technology, LG’s TC3D/TR3E series enables precise screen touch responses and a sleek design.

Experience Intuitive Touch and Writing

Outstanding Touch Performance

  • Precise Touch and Detailed Writing
    The screen recognizes even the smallest touch points accurately and instantly shows the response to the touch point. This kind of accuracy and granularity means that users can use IDB both as a realistic handwriting tool and for detailed complex content such as drawings.
  • Pen Thickness Variation
    The thickness of the pen can be adapted to the user’s writing speed, even when using the passive pen. Lines or characters become bolder as the writing speed increases. This makes users feel as if they are writing on paper using their usual ballpoint pen.
  • Multi-touch
    It allows multi-touches from 20 points (TR3E) to 40 points (TC3D) so that multiple participants can simultaneously use touch features.
  • Smooth Surface
    As there is no need for sensors on the bezel, little or no gap space is required between the screen and bezel, allowing for more intuitive operation and a better design.
  • Fewer Scratches and Shatter-proof
    When a user touches a screen directly, this can result in scratches on the screen or even damage to the glass. LG IDB has an advanced tempered screen coating to minimize scratches (The use of an LG magnetic stylus pen is highly recommended). In addition, its anti-shatter glass is designed to minimize harm to the user, even in the event of an external shock.
  • Intuitive Touch
    Users will find the IDB easy to use because the touchscreen feels similar to their mobile phones or tablets.
  • No Dead Zone
    Unlike IR touch screens, the display detects touch points even at the corner or edge of the display accurately.

With the most advanced built-in touch technology, IDB app supports a comfortable writing experiences.

Easy Operation

The pre-stored files* are easy to open on the screen with a simple touch.

Screen Capture & Storage
The written materials can be captured and automatically saved, which is useful when discussed content need to be stored by stages.

Easy Operation

* PDF files created using IDB can only be opened.

Floating Tool Bar
While using the writing function in IDB app mode, the user can place a floating toolbar anywhere on the screen by pressing and holding a touch point. Users can also drag it around using their fingertip or open and minimize it with a single tap, enabling comfortable and intuitive writing on the screen. Its special circular design helps users easily adopt and explore all features, even when trying the function for the first time.

**The black color is changed to white when the screen becomes blackboard.

Facilitate Efficient Collaboration Without a PCFacilitate Efficient Collaboration Without a PC

IDB app makes it possible to collaborate without the need for a PC based on the webOS smart platform. Also, it is a complete way to enhance collaboration efficiency during a meeting, by combining whole processes which includes file sharing, writing, and saving on LG IDB.

No Need For a PC
LG webOS is powered by high-performance SoC and can execute several tasks at the same time without the need for a separate media player or PC. Especially when combined with the IDB app, the LG IDB offers both interactive collaboration as well as an intuitive writing application, meaning additional licenses for IDB solution are not required.

Optimized Work-flow for Efficient Collaboration
The LG IDB app provides users with a convenient and effective meeting experience beyond expectation. Incredibly, a virtual meeting space can be created in the IDB, with participation access limited to users who enter a pin number generated by the IDB. Once the participants are in, the meeting session is ready to start.

Optimized Work-flow for Efficient Collaboration

*The IDB Duo (client app) needs to be installed for full compatibility. Please visit to download the software. When pairing devices with IDB, both devices must be connect to the same network.
**Users content will be saved in a PDF format.

Drawing Overlay on top of HDMI/DP and Save
HDMI or DP cables are still preferred among users when connecting their digital devices to IDB. LG IDB enables screen sharing using these cables. Shared screens are shown on a list on the IDB, so that a presenter can select the desired material to be displayed in full screen mode. Also, the presenter can write notes on the shared screen and save the notes with the screen, which reduces unnecessary time spent wrapping-up or announcing meeting minutes.

Annotate on Mirrored Screen and Save
The whole process mentioned above is also available using wireless connection. The only difference is that screens can be shared with an IDB via wireless connection. Whether using cables or wireless connection, all mirrored screens are shown as a list on the IDB, so the presenter is able to choose from among them. LG IDB will be key to building an environment optimized for both efficient collaboration and effective meetings.

Ensure the Best Picture Quality

LG IDB provides the best picture quality regardless of content type and viewer position.

Ensure the Best Picture Quality

LG Ultra HD Technology with Ultra-high Resolution
IDB users often use the zoom-in function to view complex images such as design drawing in more detail or write on the presentation material. The UHD resolution of 86TR3E/75TC3D features 8.3 million pixels, which is 4 times that of FHD resolution, allowing users to view details without distortion, even when zooming in on the display. Moreover, the outstanding resolution of UHD vividly delivers high-quality images or video content to meeting attendees.

LG IPS Panel with Wide Viewing Angle and True Color
Attendees in the meeting room may view the display from a wide viewing angle. The LG IPS panel has a wide viewing angle that delivers clear content, no matter where attendees are in the room. Moreover, every pixel in the IPS panel truly reproduces the image colors without distorting them. The outstanding color reproduction provides excellent user experience for employees in design industries such as architecture and fashion.

Maximize User Convenience

Auto Signal / Touch Switching
While using the IDB, it is often necessary to connect participant’s laptops so that they can share their display with others. In such cases, time is often wasted during the meeting on adjusting the external input and touch USB on the display screen. The LG IDB is designed to connect signals from the side interface first, so that a display on laptops connected to the side is immediately shown on the IDB screen and support touch functions. The original IDB display and the touch function are restored without any separate action when the laptop is disconnected from the side interface*.

Auto Signal / Touch Switching

Editable Assistive Touch Menu
It was difficult to use the menu with the conventional IDB with large screen of 65” or more, since the setting menu could only be called from the side of the screen. The Touch Menu is a subsidiary menu introduced to eliminate such inconvenience and improve user-friendliness. LG IDB users can run the desired function or change the setting from anywhere by softly pressing the screen to call up the Touch Menu**. Moreover, it is possible to edit the menu to include preferred apps.

Editable Assistive Touch Menu

Touch On/Off Key
During a presentation, the touch function is not always required. In such cases, users can turn off the function just by tapping the “Assistive Menu” key. Users only need to tap this key again to turn the touch function back on. The key is on the left-hand side of the TR3E and in the lower section of the front of the TC3D series, allowing users to easily turn the touch function on/off.

Touch On/Off Key

Multi Screen with PBP/PIP
PBP (Picture-By-Picture) features multi screen in a single display with upto 2 input sources, thus maximizing usability of large display. In addition, PIP (Picture-In-Picture) supports playing both main screen and sub screen at the same time with various layouts, so users can arrange many different usage scenarios efficiently

Multi Screen with PBP/PIP

Eye Care Support
LG IDB has several eye care features to prevent participants' eyes from growing tired during prolonged meetings. Reader mode decreases blue light, a cause of eye strain, by 70%, improving the comfort of those who are viewing the screen for a long time. Also the antiglare coating on the screen reduces reflection for better visibility. And brightness is automatically adjusted according to ambient light of the surrounding to reduce eye strain.

Eye Care Support

High Compatibility
Compatibility is critical in meeting room environments that work with multiple devices. Especially LG IDB is compatible with AV control systems, with which users can easily manage, monitor and control LG displays from one location. Also it allows video conferencing to be held reliably, as it supports connections with VCS solutions.

High Compatibility

* Pre-setting is required to perform the restore process
** The menu design(GUI) is subject to change without notice
