The best way to create and share ideas

LG Interactive Digital Board

TR3E/TC3D Series

As the use of digital devices increases and digitalized working becomes more and more common, multiple people in

different places are working together to solve problems and make important decisions. 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.

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.

Fewer Scratch and

Shatter-proof

Intuitive Touch

No Dead Zone

• 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

*

. 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.

* The use of an LG magnetic stylus pen is highly recommended.

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.

Facilitate 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.

IDB app

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.

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.

*The IDB Duo (client app) needs to be installed for full compatibility. Please visit www.lg.com/IDB 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.

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

LG has enhanced operability for IDB users.

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*.

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.

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.

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

Maximize User Convenience

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.

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.

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.
