LG TR3DJ-B CreateBoard vs. BenQ Board

LG is one of the world’s largest television brands in the world, and BenQ is one of the largest commercial TV and projector companies in the world. As schools transition from interactive whiteboards to interactive displays, IT managers are looking at alternatives to the traditional proprietary whiteboards from Smart and Promethean. The BenQ Board and the LG TR3DJ-B are the latest offerings from both companies for classroom interactive displays, so how do these latest models compare?

Here are the key elements to review:

· Lifetime, Brightness, and Contrast Comparison

· In-Person and Remote Whiteboard Functionality

· Classroom and Lesson Recording Features

· Health and Safety Features for students and teachers

· Device Management Systems

· Teacher to log in and cloud drive access

A display that is easy to read is a key feature in any classroom display. District technology professionals know that brighter displays with high contrast ratios are easier for students to read – especially from the back of the room.

The BenQ Board RP Series is over 20% brighter than the LG – and delivers higher contrast for easy-to-read text, and the display is rated for 50,000 hours of life compared to only 30,000 hours of the LG. This means the LG may need to be replaced years sooner than the BenQ Board.

Interactive displays are the ideal teaching platform for a hybrid classroom.  With the ability to run a Zoom or Team app directly from the display, as well as record and share lessons, these displays are far more functional than a projector or generic television display.  So what are the functional whiteboard features you want to look for when comparing these two displays?

Touch Sensor Technology: BenQ Fine IR vs. LG IR

To better simulate the experience of using a real marker, the best interactive displays depend on sensitive IR touch systems that are optically bonded to the glass, This delivers a smoother, more intuitive writing experience.  The BenQ Boards zero bonding system is called “FineIR,” Promethean’s system is called Vellum, while the SMART version of this is called HyprTouch.  The LG TR3DJ-B uses a traditional IR sensor system.  

Whiteboard Object Recognition & Response

 The BenQ Board RP03 can recognize up to twice as many touch points (40) as the LG TR3DJ-B CreateBoard when using Windows and has a lightning-fast 8ms response time.  Both systems have palm eraser recognition, can recognize handwriting, and write in multiple colors simultaneously.

In-Person vs Cloud Whiteboarding

Classroom and commercial environments are quite different, and many schools believe that cloud-based whiteboarding is an important innovation because it enables teachers to engage students effectively at any location without having to share the same network. 

All BenQ Boards come with integrated cloud whiteboarding software. With the teacher in the classroom, students can interact with the board in real time via their device at home, making it easy for remote tutoring or coaching.  For example, the teacher can send a link or a QR code and broadcast directly from the board to a student's Chromebook or iPad logged into their home network.  The teacher can also allow the student to interact directly on the board with the device with a single tap on the whiteboard – say to allow the student to solve the math problem on the board.   Since the system is network agnostic, it enables unprecedented flexibility for teachers and students that complement other classroom systems such as Zoom or Teams.  Powerful cloud whiteboarding features like this are why BenQ’s RP series is the world’s most-awarded education touch display.  There are no additional licensing fees for this software for the display's life.

The LG TR3DJ-B does not come with any cloud-based whiteboarding software.  The LG Air Class software will mirror the screen to a student's laptop – but it must be on the same network.  This is impractical for remote learning and can have an adverse impact on the school's bandwidth.

The ability to record, store and replay lessons to students who are not in the classroom is a key element in improving student performance in hybrid classrooms.  Why?  If a student misses a day or two of Geometry class – it could take a long time to catch up to the rest of the class and resulting in lower test scores.

How easy is it to record the lesson from the interactive display?

The best interactive displays have integrated lecture capture software that enables a teacher to record any lesson at any time using any software running on the panel and store that lesson anywhere on the school network or the cloud. 

The BenQ RP interactive display enables instant recording directly on the board from any application with a single two-finger tap.  This enables a teacher to record any lesson without opening another application.  Just tap the screen and hit record – it's that simple.  Teachers in both private and public schools around the world have used this for years to improve student performance.

The LG TR3DJ-B does not come with any lecture capture software. 

Array Microphone and Speakers

Teachers know the most effective lessons combine both visual and audio information. So how well do the BenQ RP and LG displays capture the teacher’s voice for lesson recording?

The BenQ RP & RM series display comes with a bi-directional 8-microphone array built-in capable of recording the teacher’s voice from 15 feet away. This system has advanced sound recognition software similar to a smartphone that cancels out background noise and “follows” the teacher as they move around the room.  This bi-directional technology enables a teacher to record simultaneously with other audio sources, such as commenting on a YouTube video running on the display.

The LG TR3DJ-B does not have any microphone system included in the display. 

In 2020, the COVID-19 pandemic created a new paradigm for schools and elevated the need for student and teacher safety.   BenQ has been integrating key safety features into their displays since 2017, and the latest models from BenQ RP Series and LG TR3DJ-B have a variety of safety features that school administrators are looking for.   Here is a breakdown of the important safety features on each display.

Tempered Glass with Anti-Glare coating

Both LG and BenQ displays feature heat-tempered hardened glass, that is designed to withstand a significant impact from an errant football or elbow, and will shatter into small pieces if broken to reduce the hazard of a student suffering a deep cut on exposed glass.   Both screens are treated to reduce glare. 

Anti-Microbial Coatings

Antimicrobial coatings are used to keep germs from growing on the display glass.  This feature has been available from BenQ since 2018 and is also available on other brands of interactive displays.  The BenQ RP series has been certified by Europe’s TUV against the five most common types of bacteria, including e. Coli, Salmonella, and pneumonia.  The BenQ display is also certified as classroom safe and toxin-free under Japan’s SIAA standard tests for potential risks such as long-term touch and oral toxicity.

The LG TR3DJ-B does not have any anti-microbial coatings on the glass.

Certified EyeSafe® Blue Light Protection

Doctors have recognized that blue light exposure has long-term risks to eye health and have created the EyeSafe® certification that is used by both Dell and HP to keep their customer’s eyes safe from harmful blue light when using monitors and notebooks.  Only the BenQ Board RP Series has this certification, and the BenQ Board display has sensors that dramatically reduce the amount of blue light when a teacher or student comes close to the board.  How much?  In addition to the EyeSafe certification, the BenQ board RP has also been certified by the European testing agency TUV as a low blue light display.  The LG TR3DJ-B CreateBoard does not have any third-party low blue light certifications.

LED-Flicker

Another unique safety feature of the BenQ interactive displays is the use of flicker-free screen lighting that makes long-term use of the board much easier on one’s eyes. Many optometrists are concerned that LED-powered displays can have a nearly invisible flicker that can be harmful to the eyes. This was originally a problem with LED-powered gaming monitors, and so BenQ invented a flicker-free backlight that provides great color and brightness – without the harmful flicker. The BenQ RP classroom display also has been tested and certified by TUV for flicker-free performance.

LG does not have any LED flicker-free certifications.

Classroom Air Quality

Recent studies have even demonstrated that higher levels of CO₂ in a room cause people to become drowsy and pay less attention.  Companies such as 3M have been working hard to improve the quality of the air in classrooms using advanced filters.  But can teachers and facilities managers tell if it is working?

The BenQ RP interactive display comes with a built-in CO₂ meter that alerts the teacher it’s time to open a window. BenQ even takes this approach a step further and will also alert the teacher if levels of dust and particulate matter in the room are dangerously high. 

Managing a large number of classroom interactive displays requires an effective remote management software system or Device Management Systems (DMS).  BenQ includes a license-free system that permits admins to push settings, updates, apps, and campus-wide text and video messages to any or all boards in their network.

LG does not offer a remote device management system for this model.

For Teachers: Account Management and Logging-In

Both the BenQ RP have two very different approaches to enable teachers to securely log into the display and access network and cloud files directly from the display. 

The BenQ Board RP models are on their third generation of Tap ‘N Teach technology that enables unprecedented teacher access to enable a personalized display with access to cloud-based files from any display on campus.   Here’s how it works:

The IT manager creates a teacher account in BenQ’s Account Management System software database by linking it to their Active Directory infrastructure.   Then they assign the teacher their specific rights on the panel to keep key network settings from being changed, but enabling the teacher to change their background and which apps are on the main page.

This approach enables IT managers to ensure that the settings are correct – and that there are no age-inappropriate apps loaded on the panel (such as FaceBook being on a first-grade teachers' board).  Once logged in, all of the network drive from Google, Microsoft OneNote, and school network drives are automatically connected.

The best part about Tap N’ Teach is how easy and fast it is for a teacher to use.   Using the same secure technology used for Apple Pay– a teacher tap’s the panel with their card or badge – and in a few seconds, the display is personalized for that teacher, complete with background, apps, and network connection.  When they are finished – they tap the display again, and the display returns to its generic state.  Teachers can also use a QR code that will enable them to securely type in a password on the phone to log into the display – avoiding the risk of typing directly on the board in view of the students.

The LG TR3DJ-B doesn’t have any special log-in or account management systems.  This means that anyone could change the settings on the board (such as language or network to disrupt the class).

While both models share similar features such as 4K resolution, wireless screen mirroring, and a dedicated OPS slot, understanding the key differences will help you decide which brand of interactive touch display will be right for your classroom.

It’s important to do research and consult important stakeholders before deciding which board your school district should adopt. But there are some major advantages that BenQ brings to the table that can make a difference to a school that might want more flexibility in its curriculum. When deciding on your chosen solution, consider the following differences:

·      The BenQ display is over 20% brighter than the LG, has higher contrast, and has a 50,000 hour rated life.   

·      The BenQ display includes a powerful cloud whiteboarding software ecosystem that works on any display included for free – without the cost of a premium subscription that will increase the TCO of the display.

·      The BenQ has more advanced classroom safety features, including anti-microbial glass, certified blue light filters, and a flicker-free screen that helps protect the user’s vision. BenQ uses specified hard glass, and has air quality, temperature, and humidity sensors to alert the teacher to any potential air quality risk.

·      BenQ’s Tap ‘N Teach NFC technology enables instant, wireless, secure teacher login – and even integrates with Active Directory. With a single tap, an enrolled teacher can transform any board on campus into their board in under 10 seconds.

·      BenQ Device management software allows school IT admins to manage BenQ displays, projectors, and even equipment from displays from legacy brands including Epson, NEC, Hitachi, and Casio – without requiring a subscription

·      BenQ panels are designed and tested to run a wide variety of classroom education curriculum including Smart Notebook, ActiveInspire, Google Classroom, Microsoft Whiteboard, and dozens of other curriculum software platforms (including Mimeo) to enable teachers to switch learning.
