Top 5 Large Touch Screen Monitors for Conference Rooms
The world of large-format, interactive displays can be overwhelming. Here’s a quick run-through.
Searching for the best and brightest large touch screen monitor for your office? Sounds like someone got an increase in their A/V budget.
We’re not surprised, seeing as employee experience and self-service tech is a hot topic these days, with a 2017 Deloitte study stating that almost 80 percent of executives believe it’s important to very important. One way to improve employee experience is with transparency and visibility. Large-format touch screen displays showing interactive office maps in your lobby, kitchen, and elevator bay, for example, accomplish just that.
There are obvious benefits that come from investing in office digital signage: improved wayfinding, increased visibility, simple conference room check-in, etc. But companies who take initiative to invest aren’t just spending to spend. They’re making a statement to the entire organization that they’re investing in improving the quality of employees day-to-day. They’re investing in workplace.

Large touch screen display features to look for:
For the best-case scenario when employees interact with a large format touch screen display in your office, we recommend looking for these qualities to make for a quick, easy and accurate experience.
• Multi-touch vs single-touch: if you’re looking to use software that has zoom capabilities (like Robin interactive maps), you want to look for multi-touch displays. These could also be good for large-format displays where multiple people may be trying to click around, or if the software has any added multi-touch functionality (similar to Apple’s trackpad two-finger scroll or page flip motions).
• 5-wire resistive or infrared touch screens: Between the two, they cover the best circumstances for touch screen technology from transmissivity, type of object able to be used (stylus vs. finger), and more.There are technically five different types of touch screen technology, which you can read more about here.

What if I already have a ton of traditional TVs for our office?
You’re in luck. A fair amount of the larger format touch screen technology we’ve seen works with a standard TV. Seems like the industry recognizes it’s worth reusing a standard TV and simply making it touch-enabled with an overlay “frame” of sorts. Here are a ton of size options for infrared, multi-touch overlays from OPTIR via Tyco Touch.
Where should these touch screens live?
An ideal office scenario would be to have a large-format touch screen monitor in your lobby and on each floor in the elevator bay or kitchen areas. These are often the highest-trafficked collision points in an office and therefore the places where employees would greatly benefit from seeing an interactive map and schedule of the workplace.
As your company grows, you’ll want to keep up the pace of strong internal communications and visibility. Large-format displays, especially touch screen ones, help you accomplish this objective really easily.
From wayfinding and conference room booking to internal communications of all types, having touch screens in high-traffic locations will make you look like the office admin superstar you really are. You could welcome new hires, tell everyone about a new product, or roll out a brand new software tool (like Robin) via these screens.
Make sure you have the right stakeholders and resources to keep the screens up-to-date, and then watch as the employee experience surveys improve.

in order and start with the technologies in question.
First of all, we will be interested in
interactive panels – touch displays with large diagonals that can
respond to pressure. Technologies have been available on the market for a long time, and price tags
gradually descended from heaven to earth. To assemble a full-fledged advertising rack

multi-touch support (detection of several touches at the same time, so
that with proper optimization of the software behind one panel they will be able to
work several people) and everything you need for an interactive rack.
Thin bezels around the displays themselves allow you to combine
multiple monitors into a matrix to create a truly large dynamic
surface. Other manufacturers have similar devices – NEC, Sharp
and so on. Using modern techniques and a creative approach, new stands
will be able to attract tremendous attention, launch viral advertising and much more
other (we will talk about specific examples a little later).
So, we have dealt with the technologies. It remains to be seen why

advertising on static media has existed for many decades, so our

What touch technologies are used on large screens? / Habr
Recently, devices with large touch screens (diagonal> 40”) are rapidly becoming cheaper and gaining popularity – interactive tables, information and advertising kiosks, interactive displays for business and education. In this article, I would like to make an overview of the sensor technologies that are used in such devices, with their advantages and disadvantages. I must say right away that the world of large displays in this regard is fundamentally different from the world of smartphones and tablets, in which the projective-capacitive (Projective-Capacitive Touch) technology has finally won. All the facts in this article are based on real experience with touch screens from various manufacturers.
First of all, it is worth mentioning the comparison criteria – otherwise how can we understand which technology is better and under what conditions? In this article, I will not talk about methods for measuring these parameters, since this is an extensive and separate topic. Just listing:
The resolution of the sensor should ideally not be lower than the graphical resolution of the display. For some technologies (for example, those using triangulation), this parameter is quite difficult to calculate, and often useless. In practice, touch resolution doesn’t affect usability as much as accuracy.
The accuracy of the sensor is determined by the difference between the actual touch point and the point where the touch appears on the display. On large displays, this error can reach several centimeters, depending on the technology. It is especially important that for some technologies this error can vary greatly in different areas of the screen. It very rarely makes sense to achieve recognition errors from the sensor of less than 2-3 mm, since this error is most often absorbed by the next parameter – optical parallax.
The problem with optical parallax is that touch displays are always covered with glass (to protect the sensor and keep the sensor working). And at >40” diagonals, it is technologically very difficult to make this glass less than 4 mm thick, so there can be a distance of 5 to 10 mm between the matrix itself and the glass surface on large displays. The figure below illustrates the problem of parallax (optical refractions are not shown, but the idea is clear).
The sensing distance is the distance to the display surface at which the sensor is triggered. In the case of optical sensors, this parameter can vary within 2-10 mm, and the larger the screen diagonal, the greater the sensing distance. For applications related to drawing, this parameter is extremely important. When you write or draw quickly, you tend to often lift the marker off the glass a very short distance. If this distance is less than the sensing distance, unwanted lines appear on the screen. Also, problems can occur with double clicks. The figure below shows how the actuation distance affects the appearance of extra lines when writing quickly. Don’t look at the handwriting, the sensor has nothing to do with it – I just have it clumsy.
The delay is the time interval between the actual touch of the object on the display and the moment when information about it will be available to the operating system. One of the most difficult parameters to measure. For modern sensors, the delay is from 10 to 30 ms, however, it should be remembered that the actual delay in the response of the application to user actions will be much greater due to delays in the OS, application and rendering. You can watch an excellent video from Microsoft Research, which was already on Habré, about how latency affects usability.
The sensor update rate characterizes the number of messages about the coordinates of recognized objects per unit of time. It should be remembered that for some technologies this parameter can significantly degrade depending on the number of simultaneously recognized objects.
All touch displays based on optical technologies are more or less afraid of stray illumination in the IR range. In practice, this means that optical sensors are unsuitable for outdoor displays. However, many modern optical sensors work more than well indoors (though not all).
Number of simultaneously recognized touches
I don’t think there is any need to comment on this. Let me just say that, in general, the more touches a touchscreen recognizes, the worse its other characteristics are.
So, we figured out the criteria for evaluating sensors for displays of large diagonals, now let’s move on to technologies. I will only describe those technologies that are actually used today in LCD displays of large (>40”) diagonals. Accordingly, resistive and SAW (SAW = Surface Acoustic Waves) technologies will be omitted. The advantages and disadvantages that I will talk about are also characteristic of large diagonals.
Projective Capacitive Touch
The principle of operation of the projective-capacitive technology is as follows. A grid of conductors is applied to the screen, the intersections of which can be considered as capacitors. The capacitance of these capacitors is affected by objects brought up (for example, a finger). A special controller alternately measures the capacitance at all intersections and calculates the coordinates of touches based on its change. Unfortunately, scaling this wonderful technology to large screens is not easy. This is due to the following issues:
- Transparency. Tablets and smartphones use transparent ITO (Indium-Tin Oxide) as conductor. On large diagonals, the length of the conductor is much longer, therefore, its resistance is also greater. To achieve an acceptable level of resistance, it is necessary to make the conductors wider – firstly, it is expensive, since the ITO consumption increases, and, secondly, starting from a certain diagonal, the conductors already become too wide. In reality, all PCT touchscreens larger than 40” now use copper conductors and can be easily seen with the naked eye. There are rumors about upcoming PCT sensors with silver nanowires, but I haven’t seen them live yet.
- Delay. Obviously, the number of conductors grows linearly with respect to the diagonal, and the number of their intersections grows quadratically. This means that a significantly higher polling rate is needed to provide an acceptable recognition latency. This requires more powerful controllers and is likely to cause problems with electrical pickup and transients in the conductors.
- Sensing distance. The greater the distance between the conductors, the more difficult it is to distinguish between an object that has been brought up to the screen and an object that has actually touched it. Since manufacturers have to increase this distance for the reasons outlined in point 2, this often creates real problems, since the sensor gives a message even before touch (although for some applications this can be considered a feature).
All this together makes modern large PCT displays a very good choice for information kiosks, including outdoor ones. But drawing on them is unlikely to work, and you shouldn’t expect them to be as responsive as a tablet. It is also important that a large PCT sensor is not cheap, since very few companies own the technology for its production.
Optical technology (Optical Touch).
This technology uses cameras with IR illumination to determine the position of an object. There is a definite problem with terminology here. Despite the fact that other technologies, which will be discussed below, also use optical effects in one way or another, among manufacturers of touch displays, it is customary to call optical (optical) technology based on cameras in the corners of the screen.
The principle of operation is quite simple – cameras with IR illumination are installed in two or four corners of the display. The backlights of the cameras are switched on in turn, and the corresponding camera captures the angular position of objects touching the display. Next, the controller triangulates the coordinates of the objects and transfers them to the computer.
The traditional problems of this technology were initially a large actuation distance, as well as poor performance in multi-touch mode. For example, a dual-camera sensor can work with a maximum of two touches, and then at a level suitable only for zoom gestures. Four-camera sensors work much better in multi-touch mode, but recognition errors are still frequent, and although the specifications of such sensors often indicate 4 or even 6 touches, the language does not dare to call this a real multi-touch.
At the same time, modern optical sensors, freed from childhood diseases, now provide the best combination of price and quality for indoor displays. They are especially distinguished by low latency and high accuracy, provided that they are well calibrated. Moreover, the delay of two-chamber sensors is lower than that of four-chamber ones, because the camera polling cycle is two times shorter.
IR Matrix Touch or simply IR Touch.
The principle of IR Touch technology is very simple – on two adjacent sides of the display frame there are lines of IR LEDs, and on the other two – lines of photocells. Objects touching the screen overlap the IR rays in the formed grid, and according to the data from the photocells, the controller determines their coordinates.
The technology, like optical, is very well applicable in practice. Relatively low price and good multi-touch (significantly clearer recognition of 4-6 objects than Optical Touch) make this technology very attractive for indoor displays. Until recently, the delay of IR sensors was quite high, but in the latest models it is already comparable to the delay of an optical sensor.
The disadvantage of the IR sensor is its low resolution – this can be easily detected in the drawing mode if you draw a line slightly deviating from the vertical or horizontal. However, manufacturers of IR matrices are constantly improving in this direction.
Technology based on FTIR effect (FTIR Touch).
This is probably the most famous multi-touch technology. It was on it that the first version of the Microsoft Surface (then still an interactive table) was based. The point is that IR LEDs are placed at the ends of the touch glass. As long as the glass is not touched by an object, the IR radiation remains inside the glass due to almost complete internal re-reflection. And as soon as the object is applied, the radiation begins to scatter at this point, and it can be seen by a camera located behind the screen.
This is the only technology that provides true multi-touch on large displays – more than 30 touches. The big drawback of the MS Surface (as with all FTIR Touch displays based on rear projection) was the large depth. In the case of LCD displays, this problem is solved by separating the LCD module and the backlight, as well as using multiple cameras with ultra-short throw lenses and an overlapping field of view.
Of course, such displays cannot be made thinner than 20-25 cm, and they are afraid of third-party illumination like fire. However, this price has to be paid if you need a real multi-touch.
Electromagnetic (EM Touch)
In this technology, behind the LCD module there is a panel with conductors – in fact, an antenna-receiver, and a transmitter is placed in a special active stylus. Based on changes in the electromagnetic field in the antenna, the controller calculates the position of the stylus. This technology is used in Wacom tablets and Galaxy Note S-Pen. In the case of large diagonal displays, the use of this technology is expensive, since for its implementation it is necessary to manufacture huge printed circuit boards. At the same time, displays that combine electromagnetic technology (for the stylus) with IR Touch (for the finger) would probably be the best choice if not for their price. By the way, these displays were produced by Perceptive Pixel, which was recently bought by Microsoft.
Another technology that I want to talk about is implemented in only one display – Samsung SUR40, aka the former Microsoft Surface 2, aka the current Microsoft PixelSense. The idea is as ingenious as it is technologically difficult to produce. The bottom line is that the photocells are built directly into the LCD matrix. Thanks to this, we get a real multi-touch, as well as a number of additional features.
Unfortunately, I did not have the opportunity to disassemble this display and subject it to a full series of tests. However, the experience of working with him at exhibitions broke all hopes for excellent technology. The display did not recognize small objects very well, showed a huge delay (although, perhaps, this can be attributed to software and a bad computer), and judging by the dimming of the light above the stands, it also has problems with backlighting. Well, the diagonal is only 40 ”, and there are no prospects for the appearance of other diagonals.
Panasonic TV Touch Pen
And the last technology in this review is the technology built into the new series of Panasonic Plasma TVs. The interesting thing about this technology is that the display itself does not have a sensor. The sensor, or rather the photocell, is located in a special electronic stylus. The idea is that each pixel on the screen is modulated in a specific way. When the stylus touches the screen (this is determined by a simple limit switch), the photocell calculates the coordinates using the modulation parameters (I don’t know exactly which ones) and transmits them via radio to the computer.
